Automatic Copying or Unloading of SMF Data from Logstreams

This product can be configured to automatically copy SMF data from logstreams that SMF uses to record data. The history files that are created are identical to those files created when SMF data is recorded to and dumped from MAN files.

Unlike MAN file dumping, where IFASMFDP is replaced, CA SMF Director uses the IBM logstream dumping utility, IFASMFDL, to access the data from the logstream for dumping. This utility is controlled by a driver program and three user exits that are provided.

Data is copied from SMF logstreams but not cleared from the logstreams by default. You can use standard logstream management techniques to have the data that is deleted from the logstreams after it has reached a certain age. We recommend using this technique for managing logstream SMF Data, as it reduces the overhead in archiving the data to the history files. If there is a need to delete the data from the logstreams, this product can be set up to issue the ARCHIVE directive to IFASMFDL. This directive tells IFASMFDL to delete the copied SMF data following a successful dump of the SMF data.
