zIIP with SSL System Trace

zIIP operates in SRB mode. SSL tracing requires I/O, but I/O is not allowed when in SRB mode. If SSL traces are run with zIIP in the CDZ address space i.e., using ENVIRON or CEEOPTS DD in startup JCL, it will result in either S0C1 or S0C4 or S0F8 ABENDs. Therefore, to take SSL traces while zIIP is enabled, use the GSKSRVR approach which moves I/O to the GSKSRVR address space. For further details, refer to the section on Capturing a z/OS System SSL Trace in the Troubleshooting chapter of Connect:Direct Secure+ Common Tasks.
