Increase Data Set Space Allocations

System administrators can add space to the TSF database if CA Chorus is purging TSF data more often than you would like. Adding more space enables continuous use of the database when the data area is full.

Note: For more information about the TSF database purging process, see TSF Database Purging.

Follow these steps:

1. Edit the following environment variables in the TSFZGROW job in chorus_runtime_hlq.CETJJCL. These environment variables are located under STDENV in the ZGROW step.
   1. Set the following environment variable to expand the zFS that contains the TSF database:

      GROW_SIZE_KB

      Specifies the number of kilobytes (KB) to expand the zFS by. The zFS expands to the nearest rounded-up number of cylinders. For example, with a cylinder size of 720 KB, any GROW_SIZE_KB between 1-719 KB expands the zFS by 720 KB, or one cylinder.

      Limits: A non-zero number.

   2. Set the following environment variable to verify the NTSF data set:

      NTSF_DATASET

      Specifies the pointer to the NTSF data set that was defined during the CA Chorus installation and that is currently mounted.

2. Submit the member TSFZGROW.

   Note: To run this job, you must have the required permissions to access and modify the zFS. These permissions are defined in the Site Preparation Guide.

You have successfully increased space in the zFS that contains the TSF database and helped to ensure continuous operation of the database.
