Oracle Management Server is Down in OEM 12c
I have some problems need your help .
I had installed OEM 12c for 64bit on Oracle Linux 5.7 , my DB is 11gR2 , both of the DB and Application in one cmputer . The cumputer`s Memory is 20GB , Hard disk is 300GB , CPU cors is 3 .
Once a time , the server is power off . After that , when I restart the OEM in OMS_HOME>bin , it said "Oracle Management Server is Down"
The following is my step to restart the OEM :
- su - oracle
- lsnrctl start
- sqlplus /nolog
- conn / as sysdba
- startup
- cd OMS_HOME>bin
- ./emctl start oms
and now the problem has come across , it said "Oracle Management Server is Down" ,
