Hi,

In a CICSPLEX environment with more than 15 CICS regions,a CICS maintained data table is refreshed by closing and opening the VSAM file by a batch job.Some of the transactions are abending when the VSAM file is closed.So to avoid the abends we are looking at options to not route the particluar transaction to the region in which the CDT close/open is occuring.Can this be accomplished by using CICSPLEX API to change some parameters in the CICS dynamic transaction routing or CICSPLEX WLM.We are looking at an automated batch job using CICSPLEX APIs or something similiar to do this.The idea is that this will run before batch job which close/open the file to refresh.

This one VSAM file can be updated only in one CICS region and it is defined as CDT in all 15 CICS regions.So when it gets updated that needs to be propagated to other regions with out any abends.
Can you please let me know whether there is any particular CICSPLEX API and Parameters which can be utilized to resolve the abends.Please suggest any other options or pointers so that i can explore it further?.
Thank you.

manu,

You can stop/purge the transaction in batch as shown below. In the Batch JCL that closes the vsam files, add a step to stop/kill the transactions that use that vsam file. And after you are done, then re-enable the transactions as the last step.

Hi Kolusu,
Thanks for the reply. Do you have any idea on whether the transaction would be routed to this particular region if the transaction is disabled or tranclass max set to zero in a CICS region. Our environment has one TOR and multiple AORs. The transactions are dynamically routed by CICSPLEX WLM in the TOR.I will try to check with my system folks. Please let me know if you have any thoughts on this.

Thank you,
