Oracle Management Server (OMS) startup in 12C


As 12C OEM Cloud control uses weblogic so the following has to be started whenever you want OMS to be up and running, sometimes we get error that AdminServer Could Not Be Started, so in that case we have to make sure EMGC_ADMINSERVER is up and running, this error comes when the lock files are not cleared properly, so we have to shutdown oms and clean up the files and then restart them all over again and then we will get to see the following up and running. The lock files to be cleared are in the following location

[oracle@node4 ~]$ cd /u01/app/oracle/product/gc_inst/user_projects/domains/GCDomain/servers
[oracle@node4 servers]$ ls -ltr
