EWLM provides end-to-end transaction reporting and will, in the future, provide end-to-end transaction management.

Enterprise workload management on z/OS is a co-operative function of EWLM and WLM, where WLM:

• Provides new application instrumentation services adhering to the Application Response Measurement (ARM 4.0) standard from The Open Group (www.opengroup.org)
   
• Implements the EWLM extensions of WLM Enclave services to allow applications using these services to participate in EWLM

 To achieve this, a new set of EWLM services in DLL IWMAMEWL (ALIAS EWLMPLAT) residing in library 'SYS1.SIEALNKE' has been provided.
