- ERP System: All
- MarkView Version: All
- One or several managers are not processing events
- Events take a long time to process
- It may lead to notifications being sent at incorrect times (i.e. late)
- The number of Pending Events reported in MarkView System Status is increasing
- On 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 Non-Production environment has the same jobs running
- 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$parameter is too small
- The database will process as many jobs as indicated in the job_queue_processes; the rest of the DBMS jobs (MarkView or not) will be queued.
- The job_queue_processes parameter needs to be large enough to cater for the Database DBMS jobs – some of which will be MarkView.
- Check the value of the job_queue_processes parameter in v$parameter
- On MarkView Home -> Support -> Database Job 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
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 normally except a value greater than 15
- 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 20 jobs:
- alter system set job_queue_processes= 20;
- 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.
