Table 120 includes step programs for application groups that are shipped with MIMIX and identifies the procedures where they are used. The values for the Used in Procedure column indicate the following:

  • ‘R’  - The step is required and cannot be changed or disabled.

  • ‘C’  - The step is included and can be changed or disabled.

  • ‘D’ - The step is included, shipped disabled, and can be enabled.

  • ‘M’ - The step is included when the application group type is a *DB2MIRROR, and can be changed or disabled.

  • Blank - The step is not used in the procedure

    Note: In service pack 9.0.20.00 and higher, this step replaces MXECSTNCB which ran on a backup node, and MXECSTNCR which ran on a replicate node.
    Note: If you modify the SWTUNPLAN procedure to enable this step, MIMIX-disabled constraints are always enabled without checking the data in the referenced files, and without other checks, such as for the existence of open commits. It is possible that constraints will be in violation due to different apply sessions ending at different points on the journal and that DB2 for IBM i will not be aware of constraint violations. Subsequent database corruption or application failures may occur.
