Installing ITO Agents on the Managed Nodes

General Installation Tips for Managed Nodes

• Use a symbolic link. For example, for HP-UX 10.x:

ln -s /mt1/OV /opt/OV

• Mount a dedicated volume. For example, for AIX:

mount /dev/hd4 /usr/lpp/OV

Note that for HP-UX systems (versions below 10.00),

/etc/update(1M)

does not support installation on NFS-mounted

file systems. You can also set the following

swinstall

option:

write_remote_files=true

❏ If you wish to move the management server to some other system,

you must first de-install the ITO managed node software from all
managed nodes, or change the management server entry in the
related ITO information file. For the location of this file, see
Table 10-3 on page 399.

❏ If you do not need the functionality of the ITO default operator on

your managed nodes (except on the management server), you can
purge the related information:

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

The ITO default operator may not be removed from Windows NT
managed nodes because the agents run under the operator’s account.

❏ When you upgrade or reinstall ITO software on managed nodes, make

sure that all programs and applications which use the

opcmsg(3)

opcmon(3)

API are stopped.

This is important because these and other APIs are stored in the ITO
shared library, which is over-written during ITO software upgrade or
reinstallation. For more information, see the HP OpenView
IT/Operations Developer’s Reference.
