Installation of IBM MQ classes for Java on z/OS
On z/OS, the STEPLIB used at runtime must contain the IBM MQ SCSQAUTH and SCSQANLE libraries.
From UNIX and Linux System Services, we can add these libraries by using a line in your .profile as shown in the following example, replacing thlqual with the high level data set qualifier that you chose when installing IBM MQ:export STEPLIB=thlqual.SCSQAUTH:thlqual.SCSQANLE:$STEPLIBIn other environments, you typically need to edit the startup JCL to include SCSQAUTH on the STEPLIB concatenation:
STEPLIB DD DSN=thlqual.SCSQAUTH,DISP=SHR DD DSN=thlqual.SCSQANLE,DISP=SHRParent topic: What is installed for IBM MQ classes for Java
