Re: slow in data selection

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.

 

Regards,

Rupam
