This was provided by apar APAR PM08688 on CICS TS 3.2 in 2010
Correction to previous comment. Apar PM08688 on CICS TS 3.2 provided the AIDCOUNT parameter on INQUIRE TERMINAL and INQUIRE NETNAME commands.
Regarding the remaining requested functionality we have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point. The requirement will be kept in the RFE system and might be reassessed in the future. You also have an opportunity to resubmit in twelve months time if you wish it to be reconsidered then.
Due to processing by IBM, this request was reassigned to have the following updated attributes:
Brand - Servers and Systems Software
Product family - Transaction Processing
Product - CICS Transaction Server
For recording keeping, the previous attributes were:
Brand - WebSphere
Product family - Transaction Processing
Product - CICS Transaction Server

Hi John, I think the #3 would work best for us but #2 is also workable. #1 is just nice to have.
Thanks for reviewing the request and providing the possible solutions. It's greatly appreciated.
In the spirit of exploring possible solutions, we can see two or perhaps three candidate solutions here.
1.Full SPI similar to that for TSQ. This would be a large work item and we know from past experience that AID manipulation can be complex so there would be lots of cases were we might show you things that ought not to be cancelled/deleted, or that you'd wonder about if we didn't show them. We're unlikely to go this route.
2. SPI more focused on solving the 'old AIDs' problem. Since we have AIDCOUNT on INQ TERM and PURGETYPE(CANCEL) on SET TERM, we could add something to filter the AIDs counted and which ones are cancelled (a keyword to say 'count the AIDs older than n hours' and to 'cancel AIDs older than n hours'). You'd be responsible for driving such SPIs periodically or on-demand. A reasonably sized solution.
3.A policy which allows you to tell the system that you don't want AIDs older than n hours, and CICS will periodically scan for AIDs which we'd then cancel without you needing to drive an SPI. Larger than option 2, but likely more do-able than option 1.
How do they grab you?
Ian J Mitchell, IBM Hursley.
I was not aware of the AIDCOUNT option but even with this new feature, it won't allow me to delete AIDs selectively based on how long it has been created. It would also be nice to be able to tell what trans created the AIDs.
There is an AIDCOUNT field that can be returned on CEMT or EXEC CICS INQUIRE TERMINAL to detect that there are AIDS outstanding. A CEMT/EXEC CICS SET TERM CANCEL command can be used to cancel aids queued for a specific terminal. Please explain why these commands are not sufficient.
