Detailed Description and Symptoms

Schedules are no longer working and the following error is reported in the latest RmiServer<timestamp>.log in the Master's $AW_HOME/log directory:


ORA-20999: Scheduling has encountered an exception


Investigation

There is the following message:

 

ErrorMsg: AwE-5001 Database Query Error (10/10/10 1:19 AM)

Details: ORA-20999: Scheduling has encountered an exception - Scheduling will not continue until issue is resolved - [ORA-20001: Submit_chains so_sch_seq=17370--ORA-00001: unique constraint (APWXPROD.SO_JOB_QUEUE_IDX2) violated]

ORA-06512: at "APWXPROD.AW5", line 1984

ORA-06512: at line 1

 

aw5.submit_chains


Solution

Log into sqlplus as the Oracle Applications Manager user and run the following sql:

 

select jt.so_module, sch.aw_sch_name from aw_module_sched sch, so_job_table jt where sch.aw_job_seq = jt.so_job_seq and sch.aw_sch_seq = <seq num>;

 

Replace <seq num> with the so_sch_seq from the error message.

 

This should return a chain name. 


Next, edit the schedule associated with that chain and make a change, apply it, reverse the change and re-Apply. 


This should correct the issue by re-ordering the chain and allow scheduling to continue.
