Create the Generation Data Groups for TIME-Based Split Files

To use the TIME operand with the SPLIT statement, you must establish Generation Data Groups (GDGs) for the split files that are produced. The GDG that is to be used when writing split files is indicated in the required TIMEGDG parameter on the SPLIT statement.

The names of the GDGs begin with an up-to-26 character prefix that is provided by the TIMEGDG operand on the SPLIT statement followed by .SIDxxxx, where xxxx is the SMF ID of the data being dumped.

For example, if TIMEGDG(ACCT.SMFDATA.SOURCE) is coded on a SPLIT statement, data from a system with SMF ID SYSA would be written to data sets in the ACCT.SMFDATA.SOURCE.SIDSYSA GDG. If the data came from a system with the SMF ID set to SYSB, the GDG would be ACCT.SMFDATA.SOURCE.SIDSYSB. Adding on the last node allows a SPLIT statement with the TIME operand to be shared among multiple systems.
