File Sort Utility (PFPSORT command)

BMC AMI Fast Path Online Reorg for IMS and Fast Path Reorg/EP incorporate the File Sort Utility.
This command-driven utility provides a method for invoking your installation’s sort utility to perform a sort of an input file in either root key or randomized sequence. This utility provides an efficient means to accomplish the following tasks:

  • Sort an unload file in root key sequence, which cannot be accomplished with a standard utility unload
  • Specify sort processing for any SDEPs contained in the unload file
  • Sort a file in randomized sequence in a job step that is independent of the file unload

The input to the File Sort Utility is a sequential input file for each area to be sorted. The sort function will accept any of the supported unload formats as input, and will automatically determine which format it is processing. The output will be written in HD Unload format only. The File Sort Utility can be used in offline mode only.

The File Sort Utility is executed by specifying the PFPSORT command and related keywords on the PFPSYSIN DD statement. The PFPSORT command can accept only one unload file as input and will produce only one unload file as output. If you want to sort more than one unload file in one step, you must concatenate the files on the SORTIN DD statement.

Warning

Important

In addition to the File Sort Utility, you can also use the LGBSORT feature, which offers full 64-bit storage and zIIP processor utilization.

To use LGBSORT, you must add the data set containing LGBSORT to the STEPLIB concatenation; otherwise, Fast Path/EP uses a standard sort, such as DFSORT or SYNCSORT. For more information about the STEPLIB requirements, see JCL-statements.
