Hi,

Currently I am working on a Migration project where our client had asked us to migrate IDMS database from BS2000/OSD to Z o/s environment.

We had formulated everything the strategy to be followed for this migration. During testing we have a parallel run phase.

During this parallel run phase, for batch programming side we can run the batches parallel with the same input. Batch parallel run is fine.

I got struk up in online parallel processing. As it is difficult for users to do same kind of updation in both the system. My manager is asking me to work on journal level, where I need to read the journal entries which were made during online transactions and to update the same entries in Z O/s in order to replicate the same updates before batch processing starts.

Can any one help me, whether we have any tool which we can use for this replication? Is there any other way to do same online updates in target system for this parallel run?

Your views will be of great help.

Thanks for your co-operation in advance.

Regards,
Anil

The DBA's should be able to help you out by creating copy jobs. Once the online updates are done in the old environment, run a copy job and reload this data to the new environment.

Another option could be record everything on one system and run the same script on the other system. Again, there is a risk that someone might forget to record and then you would have to depend on Journal again.
