Installation and Configuration Best Practices › Security Considerations › Background Users

Background Users

In a multisystem environment, reduce the number of background user IDs you add to security by specifying the same value for NMSUP in all regions.

Business Value:

Particularly in large complexes, this practice assists in simplifying the administration of internal background user IDs and reduces the possibility of outages associated with nonexistent, or incorrectly defined user IDs.

Additional Considerations:

CA NetMaster NM for TCP/IP uses background users to perform various tasks. By default, the NMSAF solution checks the background user IDs in advanced program-to-program communications (APPC). You must add them to your installed security product.

Note: The following NMSAF SXCTL parameters set the user ID checking: APPCCHECK and SYSCHECK.

The following list identifies the background user IDs:

• xxxxAOMP
• xxxxBLOG
• xxxxBMON
• xxxxBSVR
• xxxxBSYS
• xxxxLOGP

xxxx

Is the prefix specified by the NMSUP region job control language (JCL) parameter.

By specifying the same value for NMSUP in all regions, you only have to add one background user to security. For example, if you set NMSUP to MFNM in all regions, then the user ID for the xxxxBSYS background users in those regions is MFNMBSYS.

To use NMSUP, add the following statement to the TESTEXEC(RUNSYSIN) members for the regions, using the same xxxx value:

PPREF='NMSUP=xxxx'
