How to: Change PDS file count and file size

After you have been collecting and displaying historical data for a while, you might find it that you need to adjust the amount of data that you store. To change the amount of data, you adjust the number and size of files used in the persistent data store.

About this task

Important: The content in this section was created for and applies to the original persistent data store, referred to as PDS V1. A new PDS version (referred to as PDS V2) now exists. PDS V1 will eventually be deprecated.
To increase or decrease the file count and file size, edit the Kpp_PDS_FILE_COUNT and Kpp_PD_CYL parameter in the RTE configuration profile. The default value of Kpp_PDS_FILE_COUNT is 6, with a range of permissible values from 3 to 36. The default value of Kpp_PD_CYL is different for different agents.

After you make the desired adjustment to the number of files, refresh the profile and reallocate the PDS data sets.

Procedure

  1. In the RTE configuration profile, edit the Kpp_PDS_FILE_COUNT parameter to specify the desired number of files.
    For more information about the parameter, see Kpp_PDS_FILE_COUNT.
  2. Edit the value of Kpp_PD_CYL to change the size of each file.
    For more information about the parameter, see Kpp_PD_CYL.
  3. Submit the $PARSE job to refresh the profile.
    Tip: Because only RKANPARU data set is affected by this change, you can run the $PARSEPR job instead. On the $PARSE/$PARSESV: Create the RTE Members and Jobs panel, press F5, to access the library-specific jobs.
  4. Allocate the PDS data sets. Submit the KCIJPALO job to reallocate the PDS data sets.
    • For new RTEs that have not created the persistent data store files, submit the KCIJPALO job to allocate the PDS files.
    • For existing RTEs that already have allocated the persistent data store files, you must rename or delete the files, and then submit the KCIJPALO job to reallocate the PDS files. For more information about reallocating the PDS files, see How to: Reallocate PDS files.
  5. Submit the WKANSAMU(KCIJPW2R) job on the SUBMIT panel.
