IBM Language Environment (LE) runtimes

The following recommendations are for the LE runtime library access modifications, which might improve the performance of batch jobs running under the Batch Command Server:

• SCEERUN and SCEERUN2 runtime libraries into your LNKLST
• SCEELPA data set in your LPA list (LPALSTxx)
• Heavily used modules in the Link Pack Area (LPA)

  If these IBM® recommendations have not already been implemented in your system's environment, contact your systems' programming personnel to inquire about them.

  Performance Considerations - adjusting LE runtime options discusses the runtime options module shipped with the IBM Transformation Extender for z/OS® and set specifically to avoid known performance-degrading options.
