Before you begin

Ensure that you have installed a version of SUF (also known as XBM) that is supported for SHRLEVEL CHANGE in REORG PLUS as described in the System-requirements.

Also, ensure that you have the appropriate authorizations as described in Setting-REORG-PLUS-authorizations.

To run a SHRLEVEL CHANGE reorganization

  1. Complete the following SUF (also known as XBM) steps:

    1. Create and activate a management set that contains the appropriate snapshot object definition.
    2. Create and activate a configuration that contains the appropriate cache attributes.

    For more information, see the SNAPSHOT UPGRADE FEATURE for DB2 documentation.

  2. Specify SHRLEVEL CHANGE on the REORG command statement.
  3. (optional) Use the XBMID installation or command option to specify the SUF (also known as XBM) subsystem that you want REORG PLUS to use for snapshot processing.
  4. If you are running a reorganization that might invoke DSNUTILB, supply a mapping table name or ensure that a mapping table will be created.For more information, see Enabling-REORG-PLUS-to-invoke-DSNUTILB.
  5. Specify any additional SHRLEVEL CHANGE options as needed (see descriptions in SHRLEVEL-CHANGE-options-for-REORG-PLUS).
  6. Use the information in the remainder of this chapter to ensure that you create JCL that is appropriate for your environment and job requirements.
