SMFDLS Control Statement Reference › Dump Processing of Logstreams › Date and Time Management for Logstream Dumps

Date and Time Management for Logstream Dumps

Parameters let you specify date and time ranges. They are not needed by default because CA SMF Director keeps track of its location in the logstream and begins dumping from that point. You can even switch to MAN file recording, then back to logstream recording; CA SMF Director can handle that possibility and ensure that all of the SMF records are processed and archived.

The default start date/time values are as follows for dump processing:

First Logstream Dump

January 1, 1900 at 00:00

Subsequent Logstream Dumps

The date/time of the last record dumped in the previous dump for that system and logstream

The default end date/time for all logstream dumps is the current date and time less one minute.

We recommend that you allow CA SMF Director to manage the start and end times of SMF logstream dumps. If the recommendation is followed, most dumps can be run with only the logstream name, obtained either via control statement or from the CAILSNM DD, plus either the UNIT or STORCLAS control statements. This ensures that all of the data in the logstream is archived.

Here are typical dump control statements for SYSB. Use STORCLAS WORKDA for dynamic allocation of SYSIN statements for IFASMFDL. The logstream name is IFASMF.LOGGER1. These statements are passed to SMFDLS via the SMFDLSIN DD:

LSNAME(IFASMF.LOGGER1)
STORCLAS(WORKDA)
SID(SYSB)

Note: If the dump is to be run on SYSB, the SID control statement can also be omitted.

If the CASFDUML procedure is used and the logstream name is passed to the procedure in the START command, SMFDLSIN DD could contain these statements:

STORCLAS(WORKDA)
JCL

The JCL statement says to use the logstream name identified by the data set name defined in the CAILSNM DD.
