IBM System SSL Environment Variables on z/OS
There are some System SSL environment variables related to tracing and debug messages which must be specified before the EMS library is loaded.
Note:
Tracing is supported only on z/OS systems.
These environment variables are discussed in the IBM System Secure Sockets Layer programming guide, but a short summary is provided here:
- Set the file name (USS only) for raw trace records:
GSK_TRACE_FILE <trace file name>
GSK_TRACE <mask>
— specify255
to trace everythingThese two values enable detailed tracing of all GSK calls to a file. The file may subsequently be formatted for viewing using the
gsktrace
command.
GSK_HW_CRYPTO <crypto mask>
—65535
to enable all,0
to disable all hardware cryptographic functions.GSK_SSL_HW_DETECT_MESSAGE
— if set, causes brief messages regarding the state of the installed hardware to be written tostdout
when the application is started.
