EXTDATA Record Type - R78B

The MRXT78B and MZXT78B record definitions define the EXTDATA records created by CA JARS from SMF record 78, subtype 3, I/O Queuing Activity. One R78B record is created for each logical control unit (LCU) reported in the I/O Queuing Data Section and HyperPAV Data Sections. Data in HyperPAV sections for the same LCU (from different control units) are aggregated. The fields EXT78B_TPT to EXT78B_TSBS are aggregated from the I/O Queuing Configuration Data Section for the same LCU (from different channel paths).

For a complete description of each SMF data field listed below, refer to the z/OS MVS System Management Facilities (SMF) Guide (SA22-7630). The chapter entitled "Record Type 78 (4E) RMF Virtual Storage and I/O Queuing Activity" gives a detailed description of each field.

Additional information on the contents of RMF type 78 records can be found by assembling the RMF mapping macro SYS1.MACLIB(ERBSMFR), as in this example:

RECMAP   DSECT
         ERBSMFR (78)
         END

All of the fields listed below are found in the macro ERBSMFR and its subordinate macros.
