We noticed a directory "utils" under "WA_AGENT", which has only two files (below). We did not find them in R11.x versions.
Are they essential for the agent-client functionality. Can we exclude them?
-rwxr-xr-x 1 root root 1380538 Oct 2 09:23 agentUtils.jar
-rwxr-xr-x 1 root root 2101 Nov 14 14:09 rollback
Release: 12.0 and 12.1
Component: CA System Agent
agentUtils.jar and rollback are not required for agent functionality. They are used to to take backup (for upgrading agent) and roll back an upgrade.
