XPLink on z/OS

XPLink is a z/OS technology used by the C and C++ compilers to reduce the cost of function calling for programs written in these languages.

Many products, including WebSphere Message Broker for z/OS, use XPLink technology to improve their performance. To ensure the highest possible performance gains, WebSphere Message Broker requires as many as possible of the software components it uses to be XPLink-compliant. These include the broker, Java runtime, ODBC, and z/OS Language Environment.

The WebSphere Message Broker broker has been compiled by IBM to use XPLink technology and has been link-edited within the SMP/E environment to call the appropriate XPLink routines of the software components it uses. Normally, these XPLink-enabled components are configured during their customization, and the broker needs only to locate the appropriate libraries to become XPLink-enabled.
