How do I scan a JCL?

To do this scanning, code:

  1. For a job in a JES2 or JES3 system: //jobname JOB acct,progname,TYPRUN=SCAN.
  2. For a job in a JES2 system, where x is a class defined during JES2 initialization to force job control statement scanning: //jobname JOB acct,progname,CLASS=x.

What is Msgclass JCL?

MSGCLASS parameters used to describe where the JCL messages routed. In other words, it is used to assign an output class for output listing (SYSOUT). MSGCLASS parameter is an optional parameter. MSGCLASS specifies the output class for the job log.

What is given to print only the job statement?

Use value ‘0’ to print job-related statements. If we have code the value of 1 in JESJCL, then it prints all the JCL statements along with the procedures. If there are no procedures in a JCL, then it will only print all the JCL statements.

How do I find JCL errors?

Complete the following actions:

  1. Verify that file cimserver. env (or a link to it) is present in the /etc/wbem directory.
  2. If the user does not have permission to read the FTP.
  3. Ensure that z/OSMF is configured properly.
  4. For additional information, check the z/OSMF logs and operator messages, and correct any errors.

What is disp JCL?

DISP. The DISP parameter is used to describe the status of the dataset, disposition at the end of the job step on normal and abnormal completion. DISP is not required in a DD statement only when the dataset gets created and deleted in the same job step (like the temporary datasets).

What is the significance of Typrun parameter in JCL?

Use the TYPRUN parameter to request special job processing. The TYPRUN parameter can tell the system to: In a JES2 system, copy the input job stream directly to a sysout data set and schedule it for output processing. In a JES2 or JES3 system, place a job on hold until a special event occurs.

What is JOBLIB and Steplib in JCL?

JOBLIB and STEPLIB in JCL both are used to specify the load libraries so that that the programs that are being used in that JCL/JOB are searched in these libraries. Generally z/OS searches for the programs load module in the default system libraries where actually the IBM supplied programs are stored.
