I am working on on decommissioning project and for that I need to indentify which transaction id are in use and which are obsoleted.

Any way to find this or when did one particular tran id use last time in system?

Look at the region shutdown stats and check for usage of target transactions, programs, files, etc....

If you have access to SMF data, and your site keeps the SMF records long enough, you could do such an analysis. However, any use-based analysis is most likely going to be wrong since there may be transactions that are used once a month (or once a quarter or once a year) and these could be misidentified as obsolete when they are not.

Your absolute first reference should be the application documentation. Applications are usually obsoleted, NOT transactions -- find out which transactions belong to the application and there's your answer.

I had to do precisely this with our CICS environment. The way I approached this was to dump out all installed transaction names found in the group list (Use DFHCSDUP).

I then wrote a quick and dirty assembler routine that read in this list, and compared with a years worth of SMF data to see which of these transactions were used. If it got a hit, it was deleted from the list of transactions.

When it was finally complete, the only transactions in the list are those that have not been used in a year.
