JES Parms Display

The z/OS operating system requires Job Entry Subsystem (JES). JES controls the scheduling and submission of jobs. It is the component in a z/OS system that processes jobs and manages system input/output (I/O) processing and spooling. JES parameters determine whether the programmer’s name and job accounting information is required to run a job. The parameters can permit a job to bypass tape label processing (BLP), compromising tape file integrity. JES options can also permit users to include console operator commands in job control language (JCL). In short, JES parameters specify how and with what restrictions jobs run on the system.

CA Auditor helps you evaluate the options and parameters in effect in a JES environment. The JES parameters are important because they specify how and with what restrictions your system runs. The JES Parms Display lets you choose optional JES parameters and analyze their effect, and shows you the logon, started task, and batch conversion parameters.

CA Auditor determines whether you are running JES2 or JES3 and displays the appropriate information about your JES system. For JES2 systems, CA Auditor reports on the JOBCLASS, STCCLASS, and TSUCLASS statements. CA Auditor reads the JES parameters that it displays on the JES Parms Display from the data set where JES reads them. Unlike other CA Auditor displays, these JES values are not obtained from z/OS storage. It is possible that the JES startup parameters could be changed, or the JES procedure could be changed to point to another parameter data set after JES was started. In this case, the display might not reflect the parameters actually used to start JES.

You can specify optional parameters and JES procedure DD statements that the operator can use when initializing JES. CA Auditor shows you the effects that different options have on JES.
