Last updated on AUGUST 19, 2015
Applies to:Enterprise Manager Base Platform - Version 126.96.36.199.0 and later
Information in this document applies to any platform.
OMS version: 188.8.131.52.0
Agent Version: 184.108.40.206.0
The EM Agent is deployed and running as Linux user gridagent while the database Oracle Home is owned by oracle:
[root@<hostname> ~]# id gridagent
uid=1041(gridagent) gid=1102(oinstall) groups=1102(oinstall),1000(sshusers),1101(dba)
[root@<hostname> ~]# id oracle
uid=1002(oracle) gid=1102(oinstall) groups=1102(oinstall),1000(sshusers)
The EM job is using oracle for named credentials.
Job executes properly using user gridagent, hence, authentication should be successful. Since the jobs are failing as user oracle, it is a problem with privileges or resources.
