OBIEE iBots: status and exit codes in the S_NQ_INSTANCE table

Filed under: Uncategorized — Tags: — oracleaide @ 11:05 pm

The S_NQ_JOB contains jobs definitions. 

The S_NQ_INSTANCE table contains one row for each job run.

Two columns in S_NQ_INSTANCE shed light on what happens with an iBot.
1. EXIT_CODE: number of e-mails sent by an iBot job, after the job is completed (probably after a commit)/
2. STATUS :
0 – Completed
1 – Running
2 – Failed
3 – Cancelled
4  – Timed Out
