More precise Accounting and SQLACTIVITY Reports with separate SYNC operation

See this idea on ideas.ibm.com

Complex CICS/IMS transactions (involving multiple programs with an implicit Commit at the end) are incorrrectly presented on the Omegamon Accounting Report as well as on SQLActivity Report. By design the costs of the tough SYNC operation (two phase commit) are added to the last invoked Db2 package and it's SQLs. That leads to incorrect reports, forcing DBAdmins to concern about SQLs that are actually have no problems.
For example take the famous INSERT performance issue (usually executed as the last for a business transaction). Companies spend millions to improve an INSERT although there is no INSERT problem but the costs of the Two-Phase Commit.

There were two cases closed to establish that behaviour: TS002976436 and TS002533198.

    Still under review - changed status to "Future Consideration"

    From prior discussions, this Idea could be changed/sent to Db2 requesting that Db2 take out / separate the SYNC processing time from the application packages and report it in a separate dummy package. From discussions with Db2, we understand this would likely be declined. We understand that Db2 would likely support implementing the COMMIT “START/END” for DRDA trans then OMPE would have subsequently to implement his SQL Act.Trace/Report with calculating and reporting the COMMIT processing times. This would be standard ‘currency support’ for OMEGAMON

    We’ve been in discussion with the client and are considering opening a requirement to Db2
