Repair Utility of ONDV file on CICS Transaction history

OMEGAMON CICS is able to store CICS Transaction History in file. 
For example,
<ONLINE_VIEWER>                             
          DATA_STORE_TYPE=FILEOCMP 
          DATA_STORE_FILE_NAME=OMEGA.V551.*.RKC2HIST

It is working fine while it is running on Product Data center.

But, when Disaster Recovery situation happens, and CICS region/OM CICS Classic interface are abnomally terminated,
this History VSAM file is closed abnormally.

Concequently, when OM CICS Classic is brought up in DR datacenter,
OM CICS noticed that VSAM file is not right status, so it is initializing all existing record, and then collect new record.
 

Hence, if OM CICS is able to provide an utililty to fix VSAM file status, then we can use this file in DR continusly while seeing old records.

So, the utility should fix the file status, and remove the recent broken record.

    Hello, thank you for submitting this Idea, however the research into solutions has shown that the extra CPU overhead of constantly saving transaction data means that the cost is much higher than the benefit. In a DR situation when OMEGAMON is cancelled it does not get a chance to update the data for recovery. There is no data file recovery option as the data that is needed for the repair is kept in memory as such the only available solution is to initialize the file and start collecting new data. Please reach out if you have any questions or disagree with our decision. Regards IBM OMEGAMON Product Management
