Disaggregation Batches are Having Continued Performance Issue - Taking Unexpectedly Long Time to Process a Batch Run
(Doc ID 2229888.1)
Last updated on MAY 04, 2018
Applies to:Oracle Financial Services Revenue Management and Billing - Version 126.96.36.199.0 and later
Information in this document applies to any platform.
Disaggregation batches are having continued performance issue.
The fix PD provided with Patch 24578552 was giving very good results on partial disaggregation runs (partial means for few accounts). But there is not much difference in performance when it is run for full disaggregation (all accounts).
These are taking too long time to process.
No of. records attempted for Disagg = 6,357,713
Threads = 32
Chunk Size = 5000
Disaggregate Transactions From Date = 2015-08-01
Batch Business Date = 08-31-2015
Time taken for Batch Completion = 18:14:10 Hrs
No records in error in the Batch Run Tree
Transaction should be restored with UPLD status in expected time.
PD is expected of tuning batch with new design and it should give better performance for account based disaggregation runs.
Dis-aggregation is account based - so these tunings should bring performance improvement.
