On IBM z/OS systems, secure connections are created using IBM System SSL. To implement IBM System SSL for TIBCO Enterprise Message Service, you must set the necessary environment variables, and use the API documented in the sections below.
Additionally, the EMS client application must run within the context of a user ID which has the necessary privileges to access the IBM System SSL facility. For details about these requirements, see the section on SSL requirements in the
TIBCO EMS Client for z/OS (MVS) Installation and Reference.
There are some System SSL environment variables related to tracing and debug messages which must be specified before the EMS library is loaded. These environment variables are discussed in the IBM System Secure Sockets Layer programming guide, but a short summary is provided here:
Table 16 provides a list of the API calls used to configure IBM System SSL.
