Pre-allocating a common data store file

In most cases, you can allow Application Performance Analyzer to dynamically allocate and initialize the common data store file, which Application Performance Analyzer will try to do the first time the Application Performance Analyzer started task runs.

Your installation might have special requirements such as to what volume the common data store file is allocated, or under what SMS rules to allocate the common data store file. Under these conditions, use the JCL provided in sample job CAZCDS in hlq.SCAZSAMP to pre-allocate a new common data store file before starting the Application Performance Analyzer started task for the first time. Application Performance Analyzer will detect the file and initialize it. To pre-allocate a common data store file, edit and submit member CAZCDS in hlq.SCAZSAMP. See the instructions in the sample job for more information.
