Manage plug-in tag usage

Plug-in tags are used to reference rendering plug-ins in Web content. Use the run-wcm-admin-task-tag-usage task to find or update plug-in tags in the Web content.


Finding plug-in tags

To create a report of plug-in tags that are referenced in Web Content Manager items, cd wp_profile_root/ConfigEngine:

Note: The library specified in the command is the library to be scanned by the task. If the query parameter "library" is omitted, the default library configured with the defaultLibrary property in the WCM WCMConfigService service is used.

Note: An administrator user name and password is not required if we specify the portal administrator user name and password using the PortalAdminId and PortalAdminPwd settings in the wkplc.properties file.

Note: Before you progress to the next step and run the task in fix mode, ensure that the report mode indicates that the updates will happen as you require. A summary of the updates are shown by the command.

A detailed report of the updates that are made for each item is shown in the SystemOut.log file in wp_profile_root\logs\HCL WebSphere Portal and HCL Web Content Manager.

A detailed report of the updates that are made for each item is shown in the job log for the portal application server. If the report indicates that the update will not happen as required, change the task parameters and run the report mode again. Repeat this process until we are satisfied that the fixes are applied correctly. This is important because the fixes made by the task when run in fix mode might not be easy to undo if incorrect fixes are applied.


Replacing plug-in tags

To replace one plug-in tag type with another when referenced in web content items, cd wp_profile_root/ConfigEngine:

Note: The library specified in the command is the library to be scanned by the task. If the query parameter "library" is omitted, the default library that has been configured with the defaultLibrary property in the WCM WCMConfigService service is used.

Note: An administrator user name and password is not required if we specify the portal administrator user name and password using the PortalAdminId and PortalAdminPwd settings in the wkplc.properties file.


Extra parameter values

Use these additional task parameters to update the parameters in a plug-in tag:

Parameter Description
-DaddParam=ParameterName The name of a tag parameter to add to the 'find' tag when in fix mode.
-DaddParamValue=ParameterValue The value of the tag parameter to add to the 'find' tag when in fix mode.
-DupdateParam=ParameterName The name of the tag parameter to update on the 'find' tag when in fix mode.
-DupdateParamNewName=NewParameterName The new name of the tag parameter to update on the 'find' tag when in fix mode.
-DupdateParamValue=OldParameterValue The old value of the 'updateParam' parameter to update on the 'find' tag when in fix mode.
-DupdateParamNewValue=NewParameterValue The new value that replaces the old value in the 'updateParam' parameter on the 'find' tag when in fix mode.
-DremoveParam=ParameterName The name of a tag parameter to remove from the 'find' tag when in fix mode.
-DremoveParamValue=ParameterValue The values of the updateParam to remove from the 'find' tag when in fix mode.
-DfixBehavior=Behavior Parameter Used to determine how a fix is implemented. Valid behavior parameters are:

    allowMultipleValues

    If specified, parameters are allowed to have multiple values when you add parameter values in fix mode.

    ifParamValue:ParameterValue

    The fix is applied only to tags that have a parameter that has this value

    ifParamNotExist:ParameterName

    The fix is applied only to tags where this parameter does not exist.


Preserving dates

We can preserve the last modified date of items that are updated by the task by adding -DpreserveDates=true to the command. Otherwise, the last modified date is updated when the task is run.


Run the task for all libraries

We can run this task for all libraries by replacing the option -Dlibrary=libraryName with the option -DallLibraries=true in the command. If neither option is specified, this task processes the default library configured in the WCM WCMConfigService service using the WebSphere Integrated Solutions Console.


Run the task on a virtual portal

When this task is run on a virtual portal, add either -DVirtualPortalHostName=name or-DVirtualPortalContext=context to the command.


Parameters to set for large repositories

To prevent your session timing out before the task has finished, we can append the option -DsessionTimeOut=timeOut to the command. This sets the number of seconds in which the task must complete before its session will timeout. The default session timeout is 14,440 seconds, which is 4 hours. For large repositories, you should increase this setting. For example: -DsessionTimeOut=36000, which is 10 hours.


Examples

In this example, the plug-in tag ifEqual has been deprecated and replaced with the plug-in tag Equals. To up date all instances of the ifEqual tag in the site, run the following commands:

These commands replace the 'value1' and 'value2' parameters with 'text1' and 'text2' parameters, and then change the tag name to Equals.
