Lo primero que trate de hacer es conectarme a la BD , pero esto no me fue posible por el mismo error

Trate de conectarme con la opción -prelim, pero no me permitio ver que estaba corriendo

Entonces, sabiendo que era la BD del repositorio, mate un proceso de cliente y entre a la Base de Datos para ver que estaba corriendo

Y lo que me di cuenta es que las 496 sesiones estaban esperando con library cache lock, así que la logica me llevo a que habia un objeto invalido, pero no fue el caso, entonces lo siguiente que hice fue tratar de averiguar que objeto era el causante de esto
SQL> SELECT sid, event, p1raw, seconds_in_wait, wait_time FROM sys.v_$session_wait WHERE event like 'library cache%' AND state = 'WAITING' 2 3 4 ; SID EVENT ---------- ---------------------------------------------------------------- P1RAW SECONDS_IN_WAIT WAIT_TIME ---------------- --------------- ---------- 21 library cache lock 00000001506B62F8 48 0 22 library cache lock 00000001506B62F8 1274 0 24 library cache lock 00000001506B62F8 348 0 ...

Como puedes ver el dueño y el objeto estaban raros, y confirmando este objeto obvio no existia, entonces lo que hice, fue tratar de subir y bajar el stack de OMS, y aquí fue donde salio todo el problema

Así que lo que hice es fue ir a los logs, y lo que vi fue que el password de sysman habia sido cambiado

Una vez que cambie el password en el repositorio correctamente, pude arrancar OMS sin ningun problema

Lo que hay que entender de esto es que cambiar el password de SYSMAN en en el repositorio es un proceso, no es nada mas en la base de datos, y espero que esto te ahorre los dolores de cabeza que me dio este pequeño problema.
