Hi,
When the data selection is slow, you need to consider below points:
- Update the DB statistics for all tables/indexes in the sender system.
- Check the oracle database enqueue lock event. This issue could also be due to the process waiting to insert entries into table DMC_INDXCL. This needs to be checked by the DB administrator.
- You can also enable parallel data selection for some big tables.
It can be done for flat objects or for structured objects.
You need to use the view V_CNVMBTPRECALC, it maintain entries in
table CNVMBTPRECALCOBJ.
For ex., if a table has 20 million records then you can have the value of NUMREC as 1 million.
This would mean that there will be a job scheduled for every 1 million records.
Hope this helps.
