Software Maintenance on Managed Nodes
Managing ITO Agent Software
Managing ITO Agent Software
Frequently, managed nodes (even of the same architecture) do not run
the same OS versions. This is because different systems are used for
different purposes, for example:
❏
production systems running approved OS versions where all required
applications are available
❏
development systems running approved or latest OS versions
❏
test systems running approved or latest OS versions
Consequently, ITO has to support a growing list of OS versions. Due to
technical limitations and new technologies, future ITO versions might
not always be able to support the entire spectrum of OS versions.
Nonetheless, ITO does provide a way to control this problem by providing
internal management of the ITO agent software version.
If you install a new ITO agent version (having the same fileset name) on
a management server supporting the same (or a super) set of OS versions
as the previously installed ITO agent version, the previous ITO agent
version is erased. However, if you install a new ITO agent version on a
management server supporting only some of the previously supported
OS versions, then both ITO agent versions are kept on the management
server.
Running the script below on the management server will display a
summary of all installed ITO agent packages and the supported OS
versions.
/opt/OV/bin/OpC/agtinstall/opcversion -a
The latest possible ITO agent version supporting the OS version of the
managed node is always installed on that node. The related ITO software
for each supported architecture is available in:
/var/opt/OV/share/databases/OpC/mgd_node/vendor/ \
<platform_selector>/<ito_version>/<package_type>
If an older ITO agent package is no longer required and is not installed
on any managed node, you can remove it by running:
/opt/OV/bin/OpC/install/rm_opc.sh <platform_selector> \
<ito_version>
