Change sysman Password on 12c EM

Can not Change sysman password through sqlplus when running on Enterprise Manager. Have to use emctl to change sysman because this is used by oms. Please follow below steps to change the password

1. Stop oms

$ export OMS_HOME=/u01/app/oracle/oms12cr3/oms
$ cd $OMS_HOME/bin
$ ./emctl stop oms

do not use -all as admin server need to be up for change password 2. Modify sysman password

$ cd $OMS_HOME/bin
$ emctl config oms -change_repos_pwd -use_sys_pwd -sys_pwd <'sys password'> -new_pwd <'new sysman password'>

2. Restart all oms including Admin server

$ cd $OMS_HOME/bin
$ ./emctl stop oms -all
$ ./emctl start oms
