- ERP System: All
- MarkView Version: All
- One or several Process Managers are not processing events.
- Events are taking a long time to process.
- Both behaviors may lead to notifications being sent at incorrect times (i.e. late)
- The number of Pending Events reported in MarkView's System Status is increasing
- As seen in MarkView Home -> Support -> MarkView System Status.
- A DBMS Jobs that are normally running is not broken
- On MarkView Home -> Support -> Database Job Administration the last run is different from expected
- The ‘Broken’ column is set to ‘No’
- The number of DBMS jobs running on the database has increased
- The new DBMS jobs may not be MarkView-related
- The job_queue_processes parameter in v$parameter is too small
- The database will process as many jobs as indicated in the job_queue_processes; the rest of the DBMS jobs (MarkView or not) will be queued.
- Support Tools >DBMS Jobs will highlight in red when the number of job queue processes is too small and needs to be increased by your DBA.
- The job_queue_processes parameter needs to be large enough to cater for the Database DBMS jobs – some of which will be MarkView.
- Check the value of the job_queue_processes parameter in Support Tools >DBMS Jobs (or v$parameter).
- On MarkView Home -> Support -> Database Jobs see the current value listed towards the top of the screen
- It should also say how many MarkView DBMS job you have
- It does not indicate how many other non-MarkView DBMS jobs you have - your DBA has to confirm that so the number to which you increase is correctly high enough.
Note: If the value is not listed then please use script to find the value:
- select * from v$parameter where name = 'job_queue_processes';
- If the value is too low then please request the DBA team to increase the value.
- We typically recommend 25 or higher.
- Please confirm the value against other working environment to confirm the expected value.
- The DBA Team will be familiar with the process to change the value.
- Example to set the parameter to 25 jobs:
- alter system set job_queue_processes= 25;
- Increasing the parameter will not automatically resolve the issue. It will allow more jobs to run simultaneously which in time should allow more DBMS jobs to process events.
