We are upgrading our OPS/MVS to v13.5. We intend to replace our old NSM and forward messages using new UIM interface. Below is part of delivered USSENV of v13.5 that is related to tng:
As we are going to use new UIM interface, can I comment out the above lines?
Release : 13.5
Component : OPS/MVS
The lines in question pertain to the USSENV00 member of the CCLXCNTL dataset distributed with OPS/MVS. If you are not using NSM, or tng framework, you can comment out the variables pertaining to that section of the USSENV00 member. They are only required if you plan to use the Event Management component of this framework.
For testing purposes, it is recommended to leave them in the USSENV00. During the transition to UIM, set both USSUIM and USSCCSEM to 'YES'. WTO, WTOR, and DOM commands will then be sent to both CCS/EM and to UIM. The new UIMEVENT command will of course always be sent only to UIM.
Once satisfied that the UIM interface is working properly, set USSCCSEM to 'NO', and remove/comment the CCSEM/NSM-related statements.
For more information, after reviewing the comments in the USSENV00 member, consult the section "Install the Unix System Services" of the Installing Guide:
