HP Operations Manager for UNIX Administrator’s Reference

Installing and Updating the HPOM Configuration on the Managed Nodes
Distributing Scripts and Programs to the Managed Nodes
To avoid performance problems, do the following:
• Do Not Configure All Managed Nodes at One Time
Minimize the number of managed nodes getting new
configuration data at the same time:
— Distribute configuration to only a few nodes at a time by
using the opcragt command.
— Set a low number for maximum distribution requests by
using the ovconfchg command. For example:
/opt/OV/bin/ovconfchg -ovrg server -ns opc -set\
OPC_MAX_DIST_REQS 3
• Reduce the Process Priority of the Distribution Manager
Use the renice(1) command to reduce the process priority of the
distribution manager (opcdistm) on the management server.
• Use Selective Distribution Feature of the Distribution Manager
Prevent distribution of the particular configuration files which
are not needed on a specific node by using the Selective
Distribution feature of the Distribution Manager (opcdistm).
For details on Selective Distribution Feature, see “Selective
Distribution of User-selected Files to Managed Nodes” on
page 176.
❏ Identical Files
Use the customer file if identical files for actions|cmds|monitor
are found in the customer and vendor directories:
/var/opt/OV/share/databases/OpC/mgd_node/customer/\
/var/opt/OV/share/databases/OpC/mgd_node/vendor/\
//
• Customized Binaries
HPOM compresses the monitor|actions|cmds binaries. If a file
with a .Z extension already exists, do not put a file into the following
directory:
/var/opt/OV/share/databases/OpC/mgd_node/customer/\
/{monitor|actions|cmds}
