How do I read SMF records in mainframe?
SummaryEdit
- Read the original SMF dataset (DUMPIN DD) with the IBM IFASMFDP program (see L11 or L12 )
- Select the SMF record data you would like to process with a corresponding SYSIN DD Statement (see L11 or L12 for parameters)
- Write formatted output into a new temporary dataset (DUMPOUT DD)
How do I access my SMF records?
SMF data in the JES2 EVENTLOG data set You can use the Job Step panel of the Spool Display and Search Facility (SDSF) to view these records. To control access to this information, the EVENTLOG is protected with two SAF resources in the JESSPOOL class: nodeid . userid . jobname .
What is SMF and RMF?
RMF stores the contents of each report in an SMF record. Each SMF record contains information similar to the contents of the corresponding formatted report. For each system activity that you select, RMF collects data and formats an SMF record to hold the data.

What are SMF records mainframe?
IBM System Management Facility (SMF) is a component of IBM’s z/OS for mainframe computers, providing a standardised method for writing out records of activity to a file (or data set to use a z/OS term).
What is record type in mainframe?
You can use the record type field in the view definition to filter the data. To insert, update, or delete redefined data, client applications must use the base table name and filter the records by specifying the record type field in a WHERE clause.
What is SMF in networking?
Single Mode Fiber carries a single beam of light while Multi Mode Fiber carries multiple beams of light. SMF – a single wavelength light follows the same path along the fiber, supporting higher transmission speeds, longer distances (typical distance of 3 km) and is more expensive. Also, laser is used for transmission.
Is SMF and SAC the same airport?
Sacramento has 2 airports — 1 is the Sacramento International Airport (SMF) that manages domestic and international flights, and the other is the smaller Sacramento Executive Airport, located 3 miles south of downtown.
What is SMF message?
(1) (Standard Messaging Format) An electronic mail format for Novell’s MHS messaging system. The application puts the data into this format in order to send an email message. NGM (NetWare Global Messaging) is based on SMF-71, which supports long addresses and synchronized directories.
What is mainframe SMS?
The Storage Management Subsystem (SMS) is part of DFSMS. SMS changes the storage management approach from user-managed volumes to SMS-managed data sets residing in SMS-managed storage groups. The system, rather than the user, determines data placement and handles data backup, movement, space, and security.
What are the different types of SMF records?

Record Type 0 (00) — IPL Record Type 2 (02) — Dump Header Record Type 3 (03) — Dump Trailer Record Type 4 (04) — Step Termination Record Type 5 (05) — Job Termination Record Type 6 (06) — External Writer Record Type 6 (06) — JES2 Output Writer
What records does SMF write when a job is running?
While a job is executing, SMF writes the type 30, subtype 1, 4, and 5 records associated with each job step to the job’s EVENTLOG data set. You can use the Job Step panel of the Spool Display and Search Facility (SDSF) to view these records.
What is SMF data and how is it used?
Using SMF data describes each of these in more detail. SMF formats the information that it gathers into system-related records (or job-related records). System-related SMF records include information about the configuration, paging activity, and workload.
What is the difference between system-related and job-related SMF records?
System-related SMF records include information about the configuration, paging activity, and workload. Job-related records include information on the CPU time, SYSOUT activity, and data set activity of each job step, job, APPC/MVS transaction program, and TSO/E session. ( SMF records includes the formats of the SMF records.)
