Error running SQL and EXEC commands in parallel

Hi,

While we applying the patch 6241631 it got failed with below error

Error:

 ATTENTION: All workers either have failed or are waiting:

          FAILED: file ademusr.sql  on worker  2.

 ATTENTION: Please fix the above failed worker(s) so the manager can continue.

We got the solution for the error from a metalink and we applied the solution as below

To implement the solution, please execute the following steps:

1. On DB node connect to sqlplus as sysdba : sqlplus "/ as sysdba"
2. GRANT select on GV_$LOGFILE to SYSTEM with grant option;
3. connect system/pwd
4. GRANT select on GV$LOGFILE to em_oam_monitor_role;
