Versions of z/OS from 1.9 and higher 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 through the JCL.
If your logstream dumping needs are similar for all SMF logstreams, we recommend that you modify and use the CASFDUML procedure that has been included in the CASFPROC target library. 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 this product 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 regularly using scheduling software such as CA 7.
Samples of control statements and JCL for SMFDLS are provided for setting up dump processes. The following listed members are available in the target libraries:

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 this product. |
Typically, dump time range information is not needed for SMFDLS, which automatically determines where to resume the dump for a given logstream and SYSID. Once the dump has completed, information is kept to determine where to begin the next dump.
By default, this product is set up to copy data from the SMF logstreams with the expectation that an installation’s system logger policies remove records from the logstreams when they are no longer needed. We recommend this method of operation as it has more built-in fail-safes and uses less overhead. If you are recording SMF Data from multiple LPARs within a Sysplex to a single logstream, use this method to copy your logstream data.
This product can also be set up to delete records from the logstream once they are copied to history files and indexed. This procedure is allowed only if the SMF logstream contains SMF data from a single system.
