This section explains how to set up NDS partitions
and replicas on your servers. About Partitions and Replicas | |
A partition is a part of the
total Directory tree and contains at least one container and its
associated leaf objects. When a partition is subordinate to another in the Directory
tree, it is referred to as a child partition. The partition above
it is referred to as the parent partition. You
can make copies of a partition, called replicas, and store them
on different servers in your network. Distributing replicas reduces
network traffic by making information accessible locally and enabling
users to log in to the network even when a server is down. Replicas also provide fault
tolerance by ensuring that more than one copy of the partition information
is available. If the partition becomes corrupted, you can use a
replica to re-create it. | | | |  | NOTE: Partitions contain only NDS database information, not
file and directory data or information. | | | | |
There are four types of replicas, which are explained in the
following table: Planning and Creating
Partitions and
Replicas | |
You can create additional partitions and replicas using NetWare
Administrator or PARTMGR in DOS or Windows. Instructions for using
these utilities are included in this section. What Happens during InstallationBy default, the installation utility adds a replica of the
partition that contains the server's context only if the
total of existing replicas is fewer than three. However, if the server is not a NetWare 4™ server
and contains bindery files (SYS:SYSTEM\NET$*.SYS) a replica
is added, regardless of the number of replicas. These default settings ensure that bindery services will work
correctly for networks running both NetWare 3™
and NetWare 4 software. Additional Information Guidelines for Managing Partitions and ReplicasUse these guidelines for managing partitions and replicas: Make sure all the servers that contain
replicas are up and running before you attempt any partition operation. If you attempt a partition operation while a server (that
contains a replica) is down, NDS will not be able to synchronize,
since it will not be able to communicate with the replica on the
downed server. You can create partitions only at the container
level of the Directory tree. NDS does not require you to have a replica of the
complete database in any location; the database is designed to be
divided into usable pieces. Operations to manage partitions or replicas take
place in the background and take time to complete, since the replicas
need to be synchronized with new information. You cannot store more than one replica of the same
partition on a server. It is not necessary for all servers in your
Directory tree to store partitions or replicas unless you want to
be able to log in to every server in your tree using bindery services. You can create as many replicas of a partition as
you need; however, we recommend that you create between three and
six replicas of each partition in your Directory tree. Having too many replicas may slow down your network because
it will be busy synchronizing. You can have only one master replica.
Because partition and replica management is such a vital part
of managing your network, you should read Chapter 9 , "Managing
NetWare Directory Services," of Introduction to NetWare
Directory Services before you use the Partition Manager utilities. Additional Information Considerations Before Creating Partitions and Replicas | |
This section provides a list of items for you to consider.
We strongly recommend that you fill out the checklist in Appendix
A of Installation Handbook so that you or another network administrator
will know what partitions and replicas are stored on your servers
in case you should ever need to restore NDS. Before you create your partitions and replicas, or immediately
after they are all set up, ask yourself How many servers are on the network? What are the names of those servers? If you are creating partitions and replicas on more
than one server, how are they installed? Which server is Single Reference, which is Primary,
and which servers are Secondary? How are the replicas set up? How many are there?
On which servers do they exist? Which replicas are master? Read/write?
Read-only? Subordinate? How are your partitions set up? Which partitions
are the parents? Which partitions are the children?
After all of your partitions and replicas are set up, you
can view your data and make a note of it. To do this, see "Viewing
a List of Partitions Stored on a NetWare Server" in this
chapter or "Viewing a List of Replicas in a Partition"
or "Viewing a List of Partitions in a Directory Tree"
in this chapter. Make a note every time changes are made to the servers, partitions,
or replicas. That way, if disaster occurs to your NDS tree, you
or another system administrator can easily check the server configurations. For information on how to restore NDS in case of failure,
see "Backing Up and Restoring NetWare Directory Services™"
in Chapter 7. Restricting Access to Partition Manager | |
As administrator, you may want to limit which users in your
network can access the Partition Manager that can be launched from
NetWare Administrator. There are two ways you can limit access to Partition Manager: Restrict rights to NWPAR.DLL (found
in SYS:PUBLIC) by giving Read and File Scan rights only to those
who you want to have access to Partition Manager.
Creating a New Partition | |
A partition consists of
one or more container objects and their associated leaf objects.
It cannot contain only leaf objects. The container that is the first
object in the partition is called the "root" of
the partition. To create a new partition, you split the parent partition
to result in two partitions. The new partition becomes a child partition. For example, if you select an Organizational Unit and choose
to create it as a new partition, you are choosing to split the Organizational
Unit from its parent partition (Root, for example, which is always
a partition). The following things happen: The Organizational Unit you selected
becomes the root of a new partition. The replicas of the parent partition remain on the
same servers. Information for the new partition migrates from
the parent partition's replicas to the new partition's
replicas. The master replica of the new partition is stored
on the same server as the master replica of the parent partition.
Creating a partition may take some time, since all the replicas
need to be synchronized with the new partition information. When you create a new partition, the utility you use will
inform you that the partition is created successfully, but the actual
creating is still completing on the servers. You will need to wait
a while before performing another partition operation. Partitions can be created using PARTMGR or NetWare Administrator
in DOS or Windows. Both procedures are described in this section. Creating a Partition Using NetWare AdministratorPrerequisites A 386 or later workstation and NetWare
Administrator A minimum of 6 MB of memory available on
the workstation The Supervisor object right to the container object
you are partitioning
Procedure From the Windows Program Manager, click on the "NetWare
Administrator" icon. From the "Tools" menu, select
"Partition Manager." Partition Manager launches from the container you selected
in NetWare Administrator. To locate the container object that you want to
create as a partition, browse the "Partition Manager"
screen. If the container object does not appear in the window, browse
the Directory tree either by choosing an object to see its subordinates
or by choosing the arrow to move toward the Root. Your current context
appears in the upper left corner of the screen. For information about moving around in the "Partition
Manager" screen and selecting objects, choose the "Help"
button. Select the container object. Choose "Create as New Partition." To confirm the creation of a new partition, choose
"Yes." The new partition is created when the process is completed
on the servers. To see the partition icon that signifies that a
container is a partition, you need to refresh the screen by choosing
the up-arrow and then expanding the parent container again. A master replica is stored on the server where the parent
partition's master replica resides. An icon appears next
to the Organization (O) or Organizational Unit (OU) to show that
the container is the root of a partition. To see where the master replica is stored, select the Organization
(O) or Organizational Unit (OU) that you just partitioned, and then
choose "Replicas." The server name appears in
the "Servers" column and "Master"
appears next to it in the "Type" column. If you want to make additional replicas of this partition,
see "Creating a Replica" in this chapter.
Additional Information Creating a Partition Using PARTMGRPrerequisites A workstation running DOS 3.30
or later and PARTMGR A minimum of 512 KB of memory available
on the workstation The Supervisor object right to the container object
you are partitioning
Procedure At the DOS prompt, type From the "Partition Administration"
menu, select "Manage Partitions." Your current context appears in the upper left corner of the
screen. Select the container object to partition. If the container you want to partition
appears in the list, select it and press <F10>. If the container is not in the list, browse the
directory by selecting containers and pressing <Enter>
until you see the container you want. Select it and press <F10>.
Choose "Yes" to create the new
partition. The new partition is created when the process is completed
on the servers. To see the partition icon that signifies that a
container is a partition, you need to refresh the screen by choosing
the up-arrow and then expanding the parent container again. A master replica is stored on the server where the parent
partition's master replica resides. An icon appears next
to the Organization (O) or Organizational Unit (OU) to show that
the container is the root of a partition. To see where the master replica is stored, select the Organization
(O) or Organizational Unit (OU) that you just partitioned, and then
choose "View/Edit Replicas." The server name appears
in the "Replicas Stored on Server" column, and
"Master" appears next to it in the "Type"
column. If you want to make additional replicas of this partition,
see "Creating a Replica" in this chapter.
Additional Information Merging Partitions | |
You might want to merge two partitions if the Directory information
in the partitions is closely related. In other words, you would
merge a partition with its parent partition when you want to delete
the partition without deleting the objects in the partition. Consider keeping partitions separate if the newly combined
partitions would be large, because large partitions slow down response
time. The partitions are merged when the process is completed on
the servers. To see that the icon of the partition you merged is
gone (which signifies that the merge is complete), you need to refresh
the screen by choosing the up-arrow and then expanding the container
again. Merging a partition with its parent partition might take some
time, since the replicas need to be deleted and the parent replicas
updated with the merging partition information. You can merge a subordinate partition with its parent partition
using either
NetWare Administrator or PARTMGR. Both procedures are documented
in this section. Merging Partitions Using NetWare AdministratorPrerequisites A 386 or later workstation and NetWare
Administrator A minimum of 6 MB of memory available on
the workstation The Supervisor object right to the object and its
parent partition
Procedure From the Windows Program Manager, click on the "NetWare
Administrator" icon. Choose "Partition Manager" from
the "Tools" menu. To locate the container object that you want to
merge with the parent partition, browse the "Partition
Manager" screen. If the partition object does not appear in the window, browse
the Directory tree by either selecting an object to see its subordinates
or by choosing the arrow key to move toward the Root. Your current
context appears in the upper left corner of the screen. For information about moving around in the "Partition
Manager" screen and selecting objects, choose the "Help"
button. Select the partition you want to merge. Choose "Merge Partition." To merge the partition with its parent, choose "Yes." The partition is merged when the process is completed on the
servers. To see that the icon of the partition you merged is gone
(which signifies that the merge is complete), you need to refresh
the screen by choosing the up arrow and then expanding the container
again. Merging a partition with its parent partition might take some
time, since the replicas need to be deleted and the parent replicas
updated with the merging partition information. The replicas of the partitions are also merged. A partition with no parent merges with the Root partition.
Additional Information Merging Partitions Using PARTMGRPrerequisites A workstation running DOS 3.30
or later and PARTMGR A minimum of 512 KB of memory available
on the workstation The Supervisor object right to the object at the
root of the parent partition
Procedure At the DOS prompt, type From the "Partition Administration"
menu, choose "Manage Partitions." Select the partition to merge. If the partition appears in the list,
select it and press <F10>. If the partition is not on the list, browse the
directory by selecting objects and pressing <Enter> until
you see the partition you want. Select it and press <F10>.
Choose "Merge with the Parent Partition." Choose "Yes" to merge the selected
partition with the parent. The partition is merged when the process is completed on the
servers. To see that the icon of the partition you merged is gone
(which signifies that the merge is complete), you need to refresh
the screen by choosing the up arrow and then expanding the container
again. Merging a partition with its parent partition might take some
time, since the replicas need to be deleted and the parent replicas
updated with the merging partition information.
Additional Information Moving a Partition | |
You can move a container object only if it is the root of
a Directory partition that has no subordinate partitions. Moving
a
container is really moving a
partition. When you move a container object, NDS changes all references
to the container. Although the object's common name remains
unchanged, the context name of the container (and of all its subordinates)
changes. When you move a partition, you should create an Alias object
that points to the partition you are moving. Doing so allows users
to continue logging in to the network and finding objects in their
original Directory tree location. You can use NetWare Administrator or NETADMIN to move partitions
in the Directory tree. Both procedures are documented in this section. Moving a Partition Using NetWare AdministratorPrerequisites A workstation running Windows 3.1
and NetWare Administrator The Supervisor right to the object you want to move The Create object right to the destination container
Procedure From the Windows Program Manager, click on the "NetWare
Administrator" icon. From the "Tools" menu, choose
"Partition Manager." From the "Partition Manager" browser,
select the partition that you want to move. You can move a container object only if it is the root of
a partition and it contains no subordinate partitions. In Partition Manager, the partition icon appears to the left
of the object icon. If the container you want to move is not a partition,
select the container and choose "Create as New Partition."
Then refresh the screen so that the partition icon appears and go
to the next step. If there are subordinate partitions in the container you want
to move, you can merge those partitions with their parent partition. From the "Object" menu, choose
"Move Partition." Select the browser button to the right of the "Destination"
box. Use the browser in the "Directory Context"
box to view the Directory tree's containers. The "Objects" box that appears in the lower
left corner shows the containers that you select in the "Directory
Context" box. From the "Objects" box, select
a container object (an Organization or Organizational Unit) as the
location to move the listed objects to; then choose "OK." Choose "Create Alias in Place of Moved
Container." The Alias object will point to the partition's new
location. If you move an object and do not create an alias, users who
are unaware of the object's new location will not easily
find objects in the Directory tree, since they will look for them
in their original Directory tree location. This might also cause client workstations to fail at login
if the NAME CONTEXT parameter in the NET.CFG file is set to the
original location in the Directory tree. Because the context of an object changes when you move it,
users whose name context in their configuration file (NET.CFG file)
references the moved object need to update their NET.CFG so that
it references the object's new name. To automatically update users' NET.CFG file with
a new name context after moving an object, use the NCUPDATE utility.
For instructions, see "NCUPDATE" in Utilities
Reference. In the "Move" dialog box, choose
"OK." If you chose to create an alias in place of the moved container,
NetWare Administrator polls for the creation of the Alias object
before it moves the selected partition. Unless you want the partition you just moved to remain a partition,
you should merge it with its parent partition to avoid having an
unnecessary partition in the Directory tree. See "Merging
Partitions" in this chapter. You need to wait for processes throughout the Directory tree
to be complete before you can perform another partition operation
with this object.
Additional Information Moving a Partition Using NETADMINPrerequisites A DOS workstation running DOS 3.30
or later and NETADMIN The Create object right to the destination container
Procedure At the DOS prompt, type For information on moving around in NETADMIN and selecting
objects, press <F1> after starting the utility. To see
which container objects in the Directory tree are partitions, exit
NETADMIN and type "PARTMGR" at the command line.
Then browse the tree. From the NETADMIN options menu, choose "Manage
Objects." Your current context appears in the upper left corner. Select the object that you want to move. If the object you want to move appears
on the list, select it and press <F10>. If the object is not on the list, browse the directory
by selecting container objects and pressing <Enter> until
you see the object you want. Select it and press <F10>.
From the "Actions" menu, choose
"Move." You can move a container object only if it is the root of
a Directory partition and it contains no subordinate partitions. In NETADMIN, when you select a container object that is a
partition, the context-sensitive help at the bottom of the screen
reads "This is a partition." Also, an asterisk
(*) is displayed in front of the object name. If the container you want to move is not a partition, you
must use a partition- management utility (PARTMGR or NetWare Administrator)
to create the container as a new partition. Use the down-arrow key and highlight the "New
Context" field. Assign a new context to the object you want to move. If you know the new context that you
want the object to be in, type the new context in the highlighted
field. If you do not know the new context that you want
the object to be in, press <Insert> twice to browse the
Directory tree for the destination container; then select the destination
container and press <F10>.
To accept the new context as the destination container,
press <Enter>. To confirm that you want to move the object listed
in the "Old Context" field to the container listed
in the "New Context" field, press the <F10>
key. To create an alias in place of the moved container,
choose "Yes." The Alias object will point to the partition's new
location, and the selected object is moved to the destination container. If you move an object and do not create an alias, users who
are unaware of the object's new location will not easily
find objects in the Directory tree, since they will look for them
in their original Directory tree location. This might also cause client workstations to fail at login
if the NAME CONTEXT parameter in the NET.CFG file is set to the
original location in the Directory tree. Because the context of an object changes when you move it,
users whose name context in their configuration file (NET.CFG file)
references the moved object need to update their NET.CFG so that
it references the object's new name. To automatically update users' NET.CFG file with
a new name context after moving an object, use the NCUPDATE utility.
For instructions, see "NCUPDATE" in Utilities
Reference. You need to wait for processes throughout the Directory tree
to be completed before you can perform another partition operation
with this object.
Unless you want the partition you just moved to remain a partition,
you should merge it with its parent partition to avoid having an
unnecessary partition in the Directory tree. See "Merging
Partitions" in this chapter. Additional Information Aborting
a Partition Operation | |
If you have begun the process of creating, merging, or moving
a
partition, or changing a replica type, you can often abort the process,
because partition operations take time. You can abort a partition
operation only before the operation is in its final stages. You should use this feature if you begin a partition operation
and find that your database will not synchronize. If NDS cannot synchronize replica information in your database
because the database or replica information is corrupted, or because
a server in your Directory tree is down, you probably should abort
any partition operation in progress. If you choose to abort a partition operation when there is
no operation in progress, no partitions are affected. You can abort a partition operation using NetWare Administrator
or PARTMGR. Both procedures are described in this section. Aborting a Partition Operation Using NetWare AdministratorPrerequisites A 386 or later workstation and NetWare
Administrator A minimum of 6 MB of memory available on
the workstation The Supervisor object right to the object at the
root of the partition
Procedure From the Windows Program Manager, click on the "NetWare
Administrator" icon. From the "Tools" menu, choose
"Partition Manager." To locate the partition that is executing a partition
operation, browse the "Partition Manager" screen. If the container object does not appear in the window, browse
the tree by either selecting an object to see its subordinates or
by selecting the arrow key to move toward the Root. Your current
context appears in the upper left corner of the screen. For information about moving around in the "Partition
Manager" screen and selecting objects, choose the "Help"
button. Select the partition that is executing a partition
operation and choose "Abort Partition Operation." As long as at least one of the replicas has not yet completed
the operation (as shown in the "State" box), you
can abort the operation. To abort the partition operation, choose "Abort"
and then choose "Yes." The partition operation is aborted and any replicas that have
been merged, created, or moved (depending on the operation you had
begun) are returned to their original Directory tree locations.
Additional Information Aborting a Partition Operation Using PARTMGRPrerequisites A workstation running DOS 3.30
or later and PARTMGR A minimum of 512 KB of memory available
on the workstation The Supervisor object right to the object at the
root of the partition
Procedure At the DOS prompt, type From the "Partition Administration"
menu, choose "Manage Partitions." Your current context appears in the upper left corner. Select the parent partition that is involved in
a partition operation. If the partition appears in the list,
select it and press <F10>. If the partition is not on the list, browse the
directory by selecting objects and pressing <Enter> until
you see the partition you want. Select it and press <F10>.
Choose "Abort Partition Operation." A list of the replicas of the selected partition appears.
Each replica's type and state are also displayed. As long as at least one of the replicas has not yet finished
the operation you began, you can abort the operation. If the state
of the replica is "On," all operations are complete
and cannot be aborted. To abort the partition operation, press <F10>
and choose "Yes." The partition operation is aborted, and any replicas that
began to be merged or created (depending on the operation you had
begun) are returned to their previous state.
Additional Information Creating a Replica | |
When
you create a partition, a master replica is created automatically
and stored on the server where the parent partition's master
replica resides. You can create additional replicas of the partition,
within these guidelines: You can have only one master replica.
Additional replicas must be read/write or read-only. For a description
of replica types, see "Planning and Creating Partitions
and Replicas" in this chapter. You can store only one replica of a partition on
a server.
Replicas can be created using NetWare Administrator or PARTMGR.
Both procedures are described in this section. Creating a Replica Using NetWare AdministratorPrerequisites A 386 or later workstation and NetWare
Administrator A minimum of 6 MB of memory available on
the workstation The Supervisor object right to the object at the
root of the partition
Procedure From the Windows Program Manager, click on the "NetWare
Administrator" icon. Select "Partition Manager" from
the "Tools" menu. Browse the "Partition Manager"
screen to locate the partition for which you want to create a replica. If the container object does not appear in the window, browse
the Directory tree either by selecting an object to see its subordinates
or by selecting the arrow key to move toward the Root. Your current
context appears in the upper left corner of the screen. For information about moving around in the "Partition
Manager" screen and selecting objects, choose the "Help"
button. Select the container object and choose "Replicas." Choose "Add Replica." Browse the objects in the "Server"
box to locate the server on which you want to store the replica. The partition you are creating the replica for appears at
the top of the screen. The context and server information changes
as you move through the Directory tree structure. Select the server you want the new replica to be
stored on. Choose the replica type you want to create. To create the replica, choose "OK."
Additional Information Creating a Replica Using PARTMGRPrerequisites A workstation running DOS 3.30
or later and PARTMGR A minimum of 512 KB of memory available
on the workstation The Supervisor object right to the object at the
root of the partition
Procedure At the DOS prompt, type From the "Partition Administration"
menu, select "Manage Partitions." Your current context appears in the upper left hand corner. Select the partition to replicate. If the partition appears in the list,
select it and press <F10>. If the partition is not on the list, browse the
directory by selecting objects and pressing <Enter> until
you see the partition you want. Select it and press <F10>.
Select "View/Edit Replicas." A list of the replicas stored on your current server appears.
The replica type is also displayed. To add a replica to the server, press <Insert>. Enter the replica information. At the "Replica Type" field, press <Enter>. Choose the type of replica you want to create from
the "Replica Type" menu at the top of the screen. At the "Store on Server" field,
press <Enter>. Type the name of the server to which you want to
add the replica, or press <Insert> to select a server from
the browser. To create the replica, press <Esc> or <F10>
and choose "Yes." The new replica appears on the list of replicas for the server.
Additional Information Deleting a Replica | |
When you delete replicas, keep the following guidelines in
mind: If a master replica becomes corrupted,
change a read/write or read-only replica on another server to a
master replica. This automatically changes the old master replica
to a read/write replica. For fault tolerance, you should maintain replicas
of the master partition on different servers.
Replicas
can be deleted using NetWare Administrator or PARTMGR. Both procedures
are documented in this section. Deleting a Replica Using NetWare AdministratorPrerequisites A 386 or later workstation and NetWare
Administrator A minimum of 6 MB of memory available on
the workstation The Supervisor object right to the object at the
root of the partition of the replica you want to delete
Procedure From the Windows Program Manager, click on the "NetWare
Administrator" icon. Select "Partition Manager" from
the "Tools" menu. Browse the "Partition Manager"
screen to locate the partition whose replica you want to delete. If the object where the container is stored does not appear
in the window, browse the Directory tree either by selecting an
object to see its subordinates or by choosing the arrow key to move
toward the Root. Your current context appears in the upper left
corner of the screen. For information about moving around in the "Partition
Manager" screen and selecting objects, choose the "Help"
button. Select the partition and choose "Replicas." Select the server you want to delete the replica
from and choose "Delete Replica." You cannot delete a master replica. If the replica you want
to delete is a master, go to a server with another replica of the
master and make it the new master replica. This automatically changes
the old master replica to a read/write replica, which you can delete. For instructions, see "Viewing a List of Partitions
in a Directory Tree" in this chapter. Choose "OK."
Additional Information Deleting a Replica Using PARTMGRPrerequisites A workstation running DOS 3.30
or later and PARTMGR A minimum of 512 KB of memory available
on the workstation The Supervisor object right to the object at the
root of the partition for the replica you want to delete
Procedure At the DOS prompt, type From the "Partition Administration"
menu, choose "Manage Partitions." Your current context appears in the upper left corner of the
screen. Select the partition that has a replica you want
to delete. If the partition appears on the list,
select it and press <Enter>. If the partition is not on the list, browse the
directory by selecting objects and pressing <Enter> until
you see the partition you want. Select it and press <F10>.
Select "View/Edit Replicas." A list of the replicas stored on your selected partition appears.
Each replica's type is also displayed. Select the replica to delete and press <Delete>. You cannot delete a master replica. If the replica you want
to delete is a master, go to a server with another replica of the
master and make it the new master replica. This automatically changes
the old master replica to a read/write replica, which you can delete. For instructions, see "Viewing a List of Partitions
in a Directory Tree" in this chapter. To delete a replica, choose "Yes."
Additional Information Sending Updates to Other Replicas | |
Although NDS automatically synchronizes the directory data
of replicas (so that each replica contains the most recent data),
you can manually start the process to synchronize (update) the directory
data of
replicas, if necessary. You should use the Directory Services Repair utility to discover
whether the data in some replicas is out of sync with the master
replica. If the data is out of sync, you would want to send updates
to those replicas manually. The data in the other replicas would
be updated and the directory data of each replica would be synchronized. You can send updates to other replicas using NetWare Administrator
or PARTMGR. Both procedures are documented in this section. Sending Updates Using NetWare AdministratorPrerequisites A 386 or later workstation and NetWare
Administrator A minimum of 6 MB of memory available on
the workstation The Supervisor object right to the object at the
root of the partition for the replicas to which you want to send
updates
Procedure From the Windows Program Manager, click on the "NetWare
Administrator" icon. From the "Tools" menu, choose
"Partition Manager." Browse the "Partition Manager"
screen to locate the partition whose replicas you want to update. If the container object does not appear in the window, browse
the Directory tree either by selecting an object to see its subordinates
or by selecting the arrow key to move toward the Root. Your current
context appears in the upper left corner of the screen. For information about moving around in the "Partition
Manager" screen and selecting objects, choose the "Help"
button. Select the partition and choose "Replicas." From the "Replicas" screen, select
which replica you want to send updates from (the one that contains
updated data) and choose "Send Updates to Other Replicas." The updated data is sent to all existing replicas of the same
partition.
Additional Information Sending Updates Using PARTMGRPrerequisites A workstation running DOS 3.30
or later and PARTMGR A minimum of 512 KB of memory available
on the workstation The Supervisor object right to the object at the
root of the partition for the replicas to which you want to send
updates
Procedure At the DOS prompt, type From the "Partition Administration"
menu, choose "Manage Partitions." Your current context appears in the upper left corner. Select the partition whose replicas you want to
update. If the partition appears on the list,
select it and press <F10>. If the partition is not on the list, browse the
Directory tree by selecting objects and pressing <Enter>
until you see the partition you want. Select it and press <F10>.
Choose "View/Edit Replicas." A list of the replicas of the selected partition appears.
Each replica's type is also displayed. Select the replica you want to send updates from
and press <F10>. Choose "Send Updates to Other Replicas." To send updates to all the other replicas, choose
"Yes." The replica information is sent to all other replicas of the
partition (including the master replica).
Additional Information Receiving Updates from Other Replicas | |
Although NDS automatically synchronizes the directory data
of replicas, (so that each replica contains the most recent data)
you can manually synchronize (update) the directory data of replicas
if they get out of sync. You should use the Directory Services Repair utility to discover
if the data in some replicas is out of sync
with the master replica. If the data is out of sync, you would want
those replicas to receive updates from the master replica manually. You cannot choose "Receive Updates From Other Replicas"
from a master replica. The master is assumed to be the most current
and accurate copy of the partition. If it is not, you should assign
one of the other replicas to be the master using the PARTMGR utility. If you choose "Receive Updates From Other Replica"
from any replica, that replica receives NDS information from the
master. You can receive updates from other replicas using NetWare
Administrator or PARTMGR. Both procedures are documented in this
section. Receiving Updates Using NetWare AdministratorPrerequisites A 386 or later workstation and NetWare
Administrator A minimum of 6 MB of memory available on
the workstation The Supervisor object right to the object at the
root of the partition for the replicas to which you want to send
updates
Procedure From the Windows Program Manager, click on the "NetWare
