Broken Oracle job

Hi,

We have two Oracle jobs on our db (7.3.4 on AIX). One is broken. I have tried to unbreak it by:

execute dbms_job.broken(,FALSE,SYSDATE)

I get a message back saying procedure executed successfully but then get the following in the alert log:

ORA-12012: Message 12012 not found; No message file for product=RDBMS, facility=ORA; arguments: [144806]
ORA-01502: Message 1502 not found; No message file for product=RDBMS, facility=ORA; arguments: [OSARCBG] [PK_CPD_FCDB_COMM]
ORA-06512: Message 6512 not found; No message file for product=RDBMS, facility=ORA; arguments: ["SYS.DBMS_UTILITY", ] [232]
ORA-06512: Message 6512 not found; No message file for product=RDBMS, facility=ORA; arguments: [] [1]

Any ideas?

Thanks in advance
