agent mount point ownership
This does not seem like a reasonable restriction to me. log of agent install:
INFO: Login name is : oracle & file owner is : oracle
INFO: ................
INFO: ERROR : The directory /apps is not owned by either the agent user oracle or by root.
INFO:
INFO: Change the onwership of /apps so that it is owned by either the agent user oracle or root.
INFO: Check complete. The overall result of this check is: Failed <<<<
Also, the agent that was installed on the machine hosting the OMS lives on a mount point owned by another user. The directories beneath /apps are owned and accessible by the agent software owner.
