Activating dynamic allocation of the repository by using DFSMDA member

To dynamically allocate the repository data set by using the dynamic allocation (DFSMDA) member for PFPEPR, use the DFSMDA member that is created during product installation.

For more information, see the Installation System documentation and the Database Products for IMS Customization documentation , or use the sample JCL that is provided in the Fast Path/EP sample library, member #PFPMDA. Then, place the dynamic allocation member in one of your STEPLIB data sets.

An example of including the DFSMDA member in the STEPLIB DD statement is shown in following figure.

 //PFP EXEC PGM=PFPMAIN,REGION=0M
//STEPLIB  DD  DISP=SHR,DSN=BMC.PFP.LOAD  --includes DFSMDA member 
//         DD  DISP=SHR,DSN=IMS.RESLIB
//
areaname DD DSN=area.dataset,DISP=SHR
//PFPSYSIN DD *
  ANALYZE DBD=dbdname,IAREA=areaname
/*

The following items need to be considered when using the DFSMDA member to dynamically allocate the repository:

Fast Path Analyzer/EP statistics will be added to the repository for each job that runs Fast Path Analyzer/EP. This includes jobs that are run for the reorganization, reload, and change functions.
Additional repository maintenance should be scheduled, such as deleting entries, to manage the size of the repository catalog.
