For version A.01.02, new features include the following:
Example configuration files
Ability to grant a certain amount of CPU per metric
Integration with Oracle databases
Integration with iCOD (instant Capacity On Demand)
Integration with SCM (Servicecontrol Manager)
Besides resource shares, the bundling of HP-UX WLM version A.01.00.02 with PRM provides:
An SNMP agent for accessing PRM data
Display of resource percentages to two decimal places (was formerly integer precision)
Expanded field length for PRM group names in PRM's monitoring utilities (30-character field was formerly 14-character field)
In-kernel memory management
This version of HP-UX WLM does not take advantage of PRM's
hierarchical groups.
HP-UX WLM can be used with any 11.x version of GlancePlus. However, GlancePlus should be used only for monitoring, and not for changing, PRM entitlements.

For more information on HP-UX Workload Manager, see the following web site:
As described earlier (“HP-UX Workload Manager”), HP-UX WLM provides goal-based workload management. This management enables automatic resource allocation and application performance management through the use of prioritized service-level objectives (SLOs). It provides this functionality by building on HP Process Resource Manager (PRM) functionality.
WLM Oracle Database Toolkit (ODBTK) A.01.00, product number T1302AA, provides an easy mechanism for feeding Oracle database metrics into HP-UX WLM.
ODBTK offers the following features:
Keeps response times for your transactions below a given level by setting response-time SLOs
Increases an instance's available CPU when a particular user connects to the instance
Increases an instance's available CPU when more than n users are connected
Increases an instance's available CPU when a particular job is active
Gives an instance n percent of the CPU for each process in the instance (This feature is available only with HP-UX WLM version A.01.02 and later.)
Gives an instance n percent of the CPU for each user connection to the instance (This feature is available only with HP-UX WLM version A.01.02 and later.)
These features are provided by ODBTK's:
Ability to gather and send Oracle database metrics (elapsed walltime and SQL values) to HP-UX WLM for use in service-level objectives
Ability to average extreme values in database metrics before sending them to HP-UX WLM (This feature maintains a more smooth and predictable stream of metrics.)
HP-UX WLM version A.01.02 on HP-UX 11.0 and HP-UX 11i
HP-UX WLM version A.01.01 on HP-UX 11.0
Oracle 8.0.x, Oracle 8.1.5, Oracle 8.1.6, and Oracle 8.1.7
Documentation includes:

| NOTE: When you purchase the Mission Critical OE, it is assumed that you want MC/ServiceGuard, NOT ServiceGuard OPS Edition. MC/ServiceGuard and ServiceGuard OPS Edition cannot coexist on the same system. Users of ServiceGuard OPS Edition are encouraged to purchase and install the Enterprise OE and then install ServiceGuard OPS Edition. For detailed installation information, see the ServiceGuard OPS Edition version A.11.13 Release Notes (B5161-90042). |

ServiceGuard Distributed Components CD. The ServiceGuard Manager version A.02.00 is being shipped on the ServiceGuard Distributed Components CD, which can automatically install ServiceGuard Manager in either English or Japanese. ServiceGuard Manager installs on three Operating System platforms: HP-UX, Linux, and Windows.
The latest upgrades of the ServiceGuard Manager GUI are also available at no charge from http://software.hp.com in the “high availability” area.
ServiceGuard Release Notes can be viewed or printed from http://docs.hp.com in the “high availability” area.
Version A.11.13 of MC/ServiceGuard includes all the features found in earlier versions in addition to new features, defect repairs, and support for new hardware configurations.
New features include the following:
Support for VxVM and CVM disk groups created with VERITAS 3.1 Volume Manager (available only on HP-UX 11i or later)
Support for up to 60 packages per cluster
Support for ServiceGuard Manager on HP-UX 11i
Support for Auto-Port Aggregation Auto Mode on Gigabit ethernet cards
Version A.11.09 of MC/ServiceGuard is for use with HP-UX 11.0 and HP-UX 11i, and has all the features found in earlier versions in addition to new functionality, defect repairs, and support for new hardware configurations.
Auto-port aggregation is fully supported with 100BaseT network interface cards. The contents of MC/ServiceGuard releases A.11.01 through A.11.08 have been incorporated, including all A.11.08 patches.
New diagnostic error messages are written to the syslog file (/var/adm/syslog/syslog.log) when an attempt to obtain the cluster lock fails. Internal error codes are returned to facilitate troubleshooting.
MC/ServiceGuard supports the online replacement of network and I/O interface cards, which is allowed by the HP-UX 11i Operating Environments.
Disk space required for MC/ServiceGuard is 47MB. The memory required is 6MB, plus 70KB per package in the cluster, plus 300KB per Event Monitoring Service (EMS) resource in the cluster. This total amount is required on all cluster nodes, regardless of whether a given package or resource is on that node or not.
The EMS-CORE file set is no longer included as part of the MC/ServiceGuard product, even though EMS (B7609BA) is still a dependency and must be installed with MC/ServiceGuard.

Multi-Computer/ServiceGuard Network File Server (MC/ServiceGuard NFS) Toolkit version A.11.11 uses MC/ServiceGuard to set up highly available NFS servers. NFS servers are hosts that "export" their local directories and make them available for client hosts for mounting. On the NFS client, these mounted directories look like part of the client's local file system. MC/ServiceGuard NFS Toolkit is a set of configuration files and control scripts which can be customized to user-specific needs.
MC/ServiceGuard is used to create high-availability clusters of HP servers. Computer systems with high-availability clusters allow applications to continue in spite of a hardware or software failure. Such systems protect users from software failures as well as from failure of a system processing unit (SPU) or local area network (LAN) component. In the event that one component fails, the redundant component takes over and MC/ServiceGuard coordinates the transfer between components.
MC/ServiceGuard NFS Toolkit versions A.11.00.05 and A.11.11.02 are major releases. Both of these versions have dependencies on MC/SG A.11.13 that provide the integrated solution for multiple MC/ServiceGuard partner software working together under the new MC/SG framework. MC/SG NFS Toolkit has been re-architected to fit under the new framework.
NFS-related control functions and variables have been extracted from MC/ServiceGuard package control script to a separate NFS specific control script, hanfs.sh. When the MC/ServiceGuard package is started, it will check for this script under the package directory, and if it exists, will invoke NFS control script.
An easy troubleshooting mechanism has been provided. Customers can easily identify if a problem resides in MC/SG NFS Toolkit from the MC/SG package log file.
MC/ServiceGuard NFS Toolkit A.11.11.02 supports VxVM as an alternative disk storage management technology.
MC/ServiceGuard NFS Toolkit can now monitor TCP services, when NFS over TCP is enabled.
MC/ServiceGuard NFS Toolkit versions A.11.00.04 and A.11.11.02 can use the same NFS package control script, configuration file, and monitor script.
Installing MC/ServiceGuard NFS Toolkit requires only about 55KB of disk space. There are no other disk space and memory requirements.
Version A.11.00.04 and A.11.00.05 is supported only on HP-UX 11.0
Version A.11.11.02 is supported only on HP-UX 11i
