IDz Debugger IMS Isolation to prevent 'DIS TRAN *' command

Debugger IMS Transation Isolation facility in ISPF pannel currently permits issuing both an IMS display command 'DIS TRAN *' to display all the existing trasactions, or issue 'DIS TRAN pattern*' with a filtering pattern, or even with the full transaction name. This option with the pattern permits getting a quicker and filtered display.

In our shop with have around 30k IMS transactions, and an IMS 'DIS TRAN *' command takes around 20 seconds to execute in a low activity time on the system, so we do not allow 'DIS TRAN *' command (i.e. users do not have authority to execute it) as it causes a noticeable performance impact, we only allow the DIS TRAN command with a pattern name, which is immediate and has no overhead.

Unfortunately, as per our discussions with IBM Debugger development, the IDz interface of IMS Isolation (upto v16) forces a 'DIS TRAN *' and does not allow using a filtering pattern. This prevents the usage of IMS Isolation in IDz to scale (having many developers causing Debugger to issue many 'DIS TRAN *' at the same time would cause a tremendous performance impact on the sytsems, and also, the developers would think the process did not work, so they would click the button once and again, causing more and more impact).

We would need the IDz interface of Debugger IMS Isolation to have the same ability than the ISP interface to permit a  'DIS TRAN pattern*' command with a filtering pattern, or even with the full transaction name. We would need it urgently, to be included in current IDz v16 version.
