Using the Duplicate Token Utility

There is no panel interface to this utility. The key data set must be specified as either a CKDS or a PKDS.

Invoke the program as a batch job.
You must have UPDATE authority to the profile in the DATASET class covering the KDS.
To generate a report for a CKDS with the fully qualified data set name of ICSF.HCR7751.CKDS, use this JCL example:
```
//DUTIL     EXEC PGM=CSFDUTIL
//SYSOUT    DD SYSOUT=*   
//SYSIN     DD *
  CKDSN(ICSF.HCR7751.CKDS)
/*
//
```

The supported option is either:

CKDSN(fully-qualified-CKDS-name)

      or

PKDSN(fully-qualified-PKDS-name)

When you invoke the program as a batch job, you receive the return and reason code in a message when the job completes. The return codes are explained in Return and reason codes for the CSFDUTIL program.

The data set name is assumed to be fully-qualified.

Note: Prior to analyzing the current CKDS or PKDS, consider temporarily disallowing dynamic CKDS and PKDS update services. If the analysis is to be performed on a CKDS or PKDS which is shared by members of a sysplex, dynamic updates of the CKDS and PKDS should be disabled on all sysplex systems until the analysis job is complete.
