Why am I seeing additional address spaces for my NetMaster Region?

NetMaster Network Automation NetMaster Network Management for SNA NetMaster Network Management for TCP/IP NetMaster File Transfer Management SOLVE


I recently applied maintenance to NetMaster 12.2 and now a USS process with the same name plus a number is being spawned on startup.
Can you tell me which PTF introduced that and are there any security changes that are needed?
I do not see any error messages, just would like to know when it was introduced


Release : 12.2

Component : CA NetMaster Network Management for TCP/IP


In Netmaster 12.2, all USS calls and commands are submitted from the NetMaster region. For this purpose, some USS commands may require an additional address space spawned with OTX type, such as onetstat.

When an additional address space is spawned, the numeric suffix it receives and the time it remains active on the system are determined by OMVS. NetMaster has no further influence once the USS call has been passed to the system.
If the USS command is issued from an user environment, the additional address space may be removed after 3mn of inactivity.

The MVS command D A,nmcs* display may show something like:

D A,NMCS*

This is working s designed.

Additional Information

In Netmaster 12.1, USS calls were done through the SOLVESSI so the SOLVESSI was showing the same behavior - spawned tasks.
