NOTE: This release of HP Systems Insight Manager supports upgrading from Service
Control Manager 3.0 Refer to Upgrading from HP Servicecontrol Manager to HP Systems Insight Manager for
details. The "\" at the end of each command line represents that the rest of
the command is on the next line.
Install the latest recommended HP-UX patches.
For a list of recommended patches refer to the HP Systems Insight Manager
Release Notes for details.
Tune the kernel using the Java-out-of-box (JavaOOB) fileset. For information
on this, go to http://www.hp.com/products1/unix/java/java2/outofbox/index.html. This
product may be available for you to install with HP Systems Insight Manager,
either as part of the download depot file containing HP Systems Insight Manager
4.2. or from the Application Release media. The kernel parameter values it
adjusts are listed in the following table.
NOTE: Java Out-of-Box is a stand-alone bundle that upon installation will
reboot the system.
Java Out-of-Box Settings
max_thread_proc
=3000
maxdsiz
=2063835136
maxfiles
=2048
maxfiles_lim

maxusers
=512
nfile
=4097
nkthread

nproc

tcp_conn_request_max
=2048
NOTE: The maxusers parameter is obsolete in HP-UX 11i v2 (B.11.23).
Using SAM or the HP-UX Kernel Configuration tool (kcweb), complete the
following manual parameter adjustments.
The JOOB file will only set the nfile parameter to 4097. Increase the nfile parameter to at least 12000. This value
might need to be increased to 30000 depending on your environment. If you
get an error that you cannot open a file, increase this value.
Set the dbc_max_pct kernel
parameter. This is the percentage of physical memory that can be dynamically
allocated for the Data Buffer Cache. It defaults to 50%, which is usually
too high. Set this variable to the percentage of your system physical memory
that equals approximately 200 MB. For example, a server with 1 GB of RAM should
have this value set at 20%.
Note: This value cannot be less than dbc_min_pct, which cannot be less than 1%.
For proper database operation, set the "semmni" kernel parameter to
a minimum value of 250, and the "semmns" kernel parameter to a minimum value
of 1024.
Note: For HP-UX 11i v2 (B.11.23) these
parameters are dynamic and when you modify the parameters a reboot of the
system is not necessary.
