CAIENF/USS Performance Improvements

CAIENF/USS Version 14.0 performance changes improve internal control block handling for the USS applications that perform considerable DUBing and UNDUBing. These improvements reduce CPU consumption for such applications.

In addition, ENF/USS’ dataspace under Version 14.0 is now associated with the CAMASTER address space rather than the z/OS MASTER address space. This association helps to isolate operating system and nonoperating system resources.

Be aware of the following important considerations:

• Having the CAMASTER address space up and running is now a requirement to run ENF/USS. The CAMASTER address space is automatically started when the CA Common Services Version 14.0 CAW0LPA data set is added to the system LPA list through ‘SYS1.PARMLIB(LPALSTxx)’ and the CAW0LINK data set is added to the system linklist through ‘SYS1.PARMLIB(LNKLSTxx)’ or ‘SYS1.PARMLIB(PROGxx)’.
• For z/OS 1.13 and later operating systems, you are no longer required to include the CAW0LPA data set in the LPA list.
