Other code
All the WebSphere MQ supplied load modules in the following libraries are reentrant and can be placed in the LPA:
- SCSQAUTH
- SCSQANLx, where x is your language letter
- SCSQMVR1
However, if you place the libraries in the LPA, whenever you apply maintenance, you will have to copy any changed modules manually into the LPA. Therefore, it is preferable to put the WebSphere MQ load libraries in the link list, which can be updated after maintenance by issuing the z/OS command REFRESH LLA.
This is particularly recommended for SCSQAUTH so that you do not have to include it in several STEPLIBs. Only one language library, SCSQANLx should be placed in the LPA or link list. The link list libraries are specified in an LNKLSTkk member of SYS1.PARMLIB.
The distributed queuing facility and CICS bridge (but not the queue manager itself) need access to the Language Environment (LE) runtime library SCEERUN. If you use either of these facilities, we need to include SCEERUN in the link list.
