How the UNIX System Services Feature Works

The UNIX System Services (USS) feature uses OPS/REXX programs and AOF rules to perform various functions.

The USS feature lets you perform the following tasks:

• Issue UNIX shell commands
• Receive command responses in REXX variables
• Monitor the creation and termination of USS processes

If the CCS for z/OS Event Management (EM) component is installed, you can also do the following:

• Access all messages appearing on the z/OS EM console in OPSLOG, including z/OS USS syslogd messages
• Take action on the z/OS EM messages using the AOF USS rule type
• Let commands and messages be sent from OPS/MVS to z/OS EM or any other CA EM platform that is connected

The combination of these facilities lets CA OPS/MVS expand its scope of automation to the z/OS UNIX domain and the CA NSM enterprise management network.

Note: NOOUTPUT mode is implied from AOF rule types that cannot wait, such as MSG, CMD, and so on. Command responses cannot be retrieved from the nowait rules.
