Snap dump utility

The snap dump utility displays HSM records in a snap dump format.

The AKDBATCH JCL in the SAKDJCL library is a template you can use to run the snap dump utility. Do not modify the AKDBATCH member directly because it is used in the automatic error correction process. Make a copy of the AKDBATCH template as a member in your personal PDS and edit the copy by adding these two DD statements at the end:

//SYSPRINT DD SYSOUT=*
//SYSIN DD *
   (dump commands here)

The sample input shown in the following figure produces a dump format of the A record, which is the Alias Name Record (MCA) that resides in the HSM MCDS. A single character that represents the type of record in the CDS and the key of the record are the two input requirements.

//SYSIN DD  *                                                     
 DUMP A HSM.HMIG.T034211.TEST1.DUASMI.J3211                       
 DUMP A HSM.HMIG.T392109.EDP.LAB.J3202

The following figure shows an example of the snap dump produced from that sample input.
