Clearing version history

You use the clear versions tool to clear the version history of an item.

Before you begin

You must first enable the clear versions tool by adding the following parameters to the WCM WCMConfigService service using the WebSphere® Integrated Solutions Console:
  • connect.businesslogic.module.clearversions.class=com.aptrix.versioncontrol.ClearVersionsModule
  • connect.businesslogic.module.clearversions.remoteaccess=true
  • connect.businesslogic.module.clearversions.autoload=false

Procedure

  1. Log in to the portal as an administrator.
  2. Open the following URL in the browser and specify details of what history details to clear: 
    http://[HOST]:[PORT]/wps/wcm/myconnect?MOD=ClearVersions&day=date&month=month&year=year&keep=number_of_entries&restrictOn=item_type&library=library_name&fix=true&preserve_dates=true
    day, month and year
    The version history will be cleared prior to the date specified in the day, month and year parameters. If no date is specified, then the date will default to one year before the current date.
    keep
    Specify the minimum number of history versions to keep. For example, if a version has not been created for over a year, and you specify to clear all versions more than a year old, but choose to keep the last five versions, all versions will be cleared except for the last five versions even though they are over a year old. If a number is not specified, then the minimum number of versions to keep will default to 10.
    restrictOn
    Select the item types to run the clear versions tool against. If no item types are specified, all item types will be processed. Use the following parameters for each item-type:
    • content
    • style for presentation templates
    • template for authoring templates
    • taxonomy
    • category
    • SiteArea
    • Workflow
    • WorkflowStage
    • WorkflowAction
    • Cmpnt for components
    library
    Enter a library name. If the library parameter is omitted, the default library that has been configured in the WCM WCMConfigService service using the WebSphere Integrated Solutions Console.

    To run this tool against all libraries you instead use &alllibraries=true. If you have a large number of libraries, this may take a long time to run, so it may be better to run this tool against individual libraries instead of all libraries.

    fix
    If omitted or set to false, a report listing which versions will be cleared is displayed. If set to true, versions will be cleared as specified.
    preserve_dates
    If set to true, the last modified date of items updated by the module is preserved. If omitted or set to false, the last modified date is not preserved.

Results

Note: You cannot completely clear all versions. One version of an item will always remain no matter what parameters you select when clearing the version history.

Running the tool on a virtual portal

There are two methods available when running the tool on a virtual portal:
Using the URL context of a virtual portal:
If your virtual portal has a URL context, you can add this to the URL 
http://[HOST]:[PORT]/wps/wcm/myconnect/[url_context]?MOD=ClearVersions
Using the hostname of a virtual portal:
If your virtual portal has a hostname you can add this to the URL 
http://[Virtual_HOST]:[PORT]/wps/wcm/myconnect?MOD=ClearVersions
