Installing HPOM Agents on the Managed Nodes
Installation Tips
❏
If you want to move the management server to some other system,
you must first de-install the HPOM managed node software from all
managed nodes. See also “Changing Hostnames and IP Addresses”
on page 411 for more information.
Purge the Functionality of the HPOM Default Operator
If you do not need the functionality of the HPOM default operator on
your managed nodes (except for the management server), you can
purge the related information. This information will be recreated
when you re-install the HPOM agent software.
UNIX:
• Erase the home directory of the user opc_op.
• Remove the opc_op entry from /etc/passwd.
• Remove the opcgrp entry from /etc/group.
MPE/iX:
• Purge the account OVOPR.
NOTE You may not remove the HPOM default operator from Windows 2000
managed nodes because the agents run under the operator’s account.
❏
Stop All Programs and Applications Using “opcmsg” APIs
When you upgrade or re-install HPOM software on managed nodes,
make sure that all programs and applications that use the
opcmsg(3) or opcmon(3) API are stopped.
These APIs as well as other APIs are stored in the HPOM shared
library, which is overwritten during HPOM software upgrade or
reinstallation. For more information, see the HPOM Developer’s
Reference.
