Oracle Realtime Scheduler Slot Booking is Not Working and Postbox Table Populated With Millions of Records (Doc ID 1089805.1)

Last updated on MARCH 08, 2019

Applies to:

Oracle Real-Time Scheduler - Version 10.1.0 to 1.13.0 [Release 10.1 to 1.13]
Information in this document applies to any platform.


Users are unable to book orders through slot requests. Millions of records are in the POSTBOX table and an extra process is in the PROCESS_STATUS table where the PROC_NAME =  "rts_ws.exe".  The POSTBOX table cleared and began to process normally when the Oracle Realtime Scheduler (ORS) Resource Manager Web Service process (rts_ws.exe) was deleted from the PROCESS_STATUS table.

Information to Gather for Issue Clarification:

1. If a process sent the Web Service a SYNC_PLAN request it can be seen in the Web Service logs. The following UNIX command will search  the logs for such an event.

gzip -dc **/*-rsrcmgr-ws*.gz | grep SYNC_PLAN | grep recv

2. The following SQL will help identifying the problem by returning the oldest message in the POSTBOX table and show time the problem occurred.

select * from POSTBOX where msg_no=(select MIN(msg_no) from POSTBOX);

3. A dump of the PROCESS_STATUS table is required to identify the offending process.

select * from PROCESS_STATUS;

4.  The scale of the problem can be seen by the number of records in the POSTBOX table.

select count(*) from POSTBOX;

5.  Obtain a dump of the POSTBOX table before clearing any records.
