Removing a Patch History of Changes

Use the Patch menu Remove Patch History command from the JADE Installation Preferences dialog to remove a history of patch number changes (summarizing the JADE development environment status line information) that meets one of the following criteria.

This command enables you to remove specific patch history information without having to extract individual patch numbers and select the Remove History After Extract option. (For details, see "Extracting a Patch Version", earlier in this chapter.) For example, if one of your JADE developers were to accidentally turn on patch versioning and it was left on while some major development work was being done on your system, the _userscm.dat file could increase to several hundred M bytes, of which approximately a third may be patch number information.

You can therefore use the Remove Patch History command to quickly strip out the patch number information that covers the period during which it was mistakenly enabled, and subsequently reclaim the database space.

To reclaim any database space, however, you must first compact your JADE database. (For details, see "Compacting Files" and "Using the Compact Files Command", in the JADE Database Administration Guide.)

You cannot remove a history of patch changes unless global patch versioning is enabled for your JADE development environment. (For details, see "Enabling or Disabling Patch Versioning", earlier in this chapter.)

You can recreate a patch version history that you have removed, if you later want to see a summary of changes made in that patch version. For details, see "Recreating a History of Patch Version Changes", earlier in this section.
