Root Cause

Data in the log file indicated that the database PARENT and CHILD Save operations failed. This occurred because the MERGE INTO statement (batch processing) did not consider WHICH case was inserted or updated first. That is, the order of CASE persistence to the database (using the MERGE INTO statement) was non-deterministic.


Perform the following local-change:

Disable the MERGE INTO statement using the following updates to the Process Commander prconfig.xml settings:

<env name="classmap/usemergestatement" value ="false" />
<env name="database/batchupdates" value="-1" />
