What is SMF dump?

The SMF data set dump program dumps the contents of multiple VSAM or QSAM data sets to sequential data sets on either tape or direct access devices. The SMF data set dump program allows the installation to route different records to separate files and produce a summary activity report.

Which dump program is used for collecting SMF dump?

Using the SMF dump programs describes the dump program for SMF data sets and log streams.

What does SMF stand for in mainframe?

SMF stands for System Management Facility, which is a component of z/OS from IBM. The purpose of SMF is to produce records of activity on a mainframe computer that are then recorded to a file. Types of activities which can be recorded by SMF include errors, software usage, network activity, and much more.

What is Jes mainframe?

The Job Entry Subsystem (JES) is a component of IBM’s MVS mainframe operating systems that is responsible for managing batch workloads. In modern times, there are two distinct implementations of the Job Entry System called JES2 and JES3. They are designed to provide efficient execution of batch jobs.

What is SMF record?

What are the difference between JCL and JES?

JCL JES stands for JOB Entry Subsystem. We use JES to accept jobs to the MVS operating system like Z/OS in Mainframe. JES acts as a Job manager.

How do I find a spooling job?

for seeing spool,

1. go to ispf main panel.
2. there u will find the sdsf option.
3. otherwise u can find spool as by giving =s.st in command line.
4. or, give as “tso sdsf st” in command line. Back to top.

What is the SMF data set dump program?

The SMF data set dump program dumps the contents of multiple VSAM or QSAM data sets to sequential data sets on either tape or direct access devices. The SMF data set dump program allows the installation to route different records to separate files and produce a summary activity report.

How does the SMF writer routine work?

When the current recording data set cannot accommodate any more records, the SMF writer routine automatically switches recording from the active SMF data set to an empty SMF data set, and then passes control to the IEFU29 SMF dump exit. The operator is then informed that the data set needs to be dumped.

Why is my SMF data set not opening?

If the SMF data set dump program is unable to open either the input or output data sets, it writes an error message indicating which data set was not successfully opened. If all SMF data sets and the SMF buffers become full, SMF will be in a data lost condition (unable to record) until dumping takes place.

Can SMF data sets be shared across systems?

SMF data sets cannot be shared across systems. IBM® does not recommend that the SMF data set dump program be run from one system in an attempt to clear a SMF data set used by another system.
