Often times it may be necessary to confirm that a CA provided fix is implemented in the running system. It may not be enough to know if the fix was installed in an SMP/E environment, although that is a good starting point. Best practices dictate that you do not run executable programs directly from the SMP/E target libraries. The SMP/E target libraries are usually copied to system runtime libraries which may also be defined to be included in the system LPA list concatenation or the system link list concatenation.
The TSO ISRDDN command is a useful tool that lets you browse/view your active TSO session libraries. It also has the capability to add the system LINKLIST libraries and LPA libraries to the list of libraries that you can view. This is useful to confirm if a CA provided fix is implemented in the system run time environment.
To begin, you will need to have (security) authorization to browse/view system libraries. You will need to know the load module name and module/CSECT. This may be given to you by CA Support to have you confirm a fix, or this can be obtained by using the SMP/E Dialog (ISPF Panels).
This technique can be used to verify a fix for most current CA Mainframe products.
If the product is not current, or if there is no #MID or RMID value, you can still check/verify a module with Date and Time stamp information seen in the eye catcher area. CA Support can match this up with a specific fix to verify that a particular fix is on.
