You will need sys password to reset sysman password.

If you don’t remember sys password you should already know how to change it from repository server… If you still thinking , ok then let’s write this step also:

  1. Connect to the database(repository) server via ssh.
  2. Describe ORACLE_SID and ORACLE_HOME variables.
  3. Connect to the database without password and with sysdba privilege:

    sqlplys / as sysdba

  4. Change sys user password:

    alter user sys identified by <sys password>;

1. Stop all OMS processes

cd <oms home>/bin
emctl stop oms

2. Change the SYSMAN password:

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

3. Stop the Admin Server on the primary OMS and restart OMS:

cd <oms home>/bin
emctl stop oms -all
emctl start oms

4. Check that oms is up and running:

cd <oms home>/bin
emctl status oms -details

That’s it.


In SQL*Plus, how do I change the prompt to show the connected user and database?

#Connect as oracle user and add the following line at the end of th glogin.sql script.

su - oracle
vi $ORACLE_HOME\sqlplus\admin\glogin.sql
set sqlprompt "_user '@' _connect_identifier > " 

#Now check

sqlplus / as sysdba
