Unloading SMF Logstreams

Versions of z/OS from 1.9 and above can also write SMF data to system logger logstreams instead of to the traditional SYSx.MANx files. This change in operation will still work with CA SMF Director, and setting up to process logstream data is similar to setting up for the SYSx.MANx files. The major difference is that the logstream must be provided to the logstream dump driver program SMFDLS in the input control statements or via the JCL.

We recommend that you modify and use the CASFDUML procedure that has been included in the CASFPROC target library if your logstream dumping needs are similar for all SMF logstreams. The procedure can be invoked with a variable that is the name of the logstream to be processed.

The CA Common Services for z/OS program CAIRIM is used by CA SMF Director to enable or disable the automatic dump feature (see the Installation Guide for more details). The intercept for IEFU29L can be used if desired, or dumps can be started on a regular basis using scheduling software such as CA 7.

Samples of control statements and JCL for SMFDLS are provided for setting up dump processes. The following members are available in the target libraries listed below:

Item Name

Target Library

Description

CASFDUML

CASFPROC

Automated dumping procedure invoked by the CA SMF Director IEFU29L intercept if installed. This procedure can also be started via a system command or within a batch job.

SMFDDUMP

CASFPARM

Standard control statements for the CA SMF Director dump process.

SMFDIN

CASFPARM

Standard control statements for the CA SMF Director logstream dump interface program.

SMFLSTBL

CASFSRC

Sample user exit that can be used to tailor the commands that are issued to the system to automatically start the dumping of logstream data by CA SMF Director.

Typically, dump time range information will not be needed for SMFDLS, which will automatically determine where to resume the dump for a given logstream and SYSID. Once the dump has completed, information will be kept to determine where to begin the next dump.
