Installing and configuring the Manufacturing Resource Library > Populating the database

Update the class hierarchy

When you are upgrading from an earlier Teamcenter version, Teamcenter checks whether you have previously installed all or parts of the library during the Manufacturing Resource Library (MRL) installation. If you have done so, you can now choose to update older class hierarchies. Teamcenter automatically checks whether first installation (database population) or an update is required for an existing structure.

This procedure assumes you have completed the steps in Beginning the installation. The installation wizard should currently display the Choose MRL Update Work Directory dialog box.

Procedure

  1. Specify the path for the MRL update files you are creating. During the course of the update, Teamcenter creates script files for the update and stores them in this directory.

  2. Click Next.Teamcenter displays the MRL Update Type Selection dialog box, where you must take action in this sequence:

Select Export existing class hierarchy. This step exports the class hierarchies that you want to update to the update directory you specified.

Click Next. Teamcenter displays the MRL Update Class Hierarchy for Modules dialog box, which contains a list of the available hierarchies, with version information. For example:

The hierarchies that need to be updated are already selected.

Select the hierarchies you want to update and click Next.

Confirm your selections and click Next. Teamcenter exports the selected hierarchies to an EXPORT directory in the update directory that you specified at the beginning of this procedure. The installation wizard returns to the MRL Update Type Selection dialog box.

(Optional) Select Modify configuration file in a text editor to specify certain objects that are not changed during the update process. Selecting this option allows you to modify the MRL_Update_Configurationfile.xml. Although it is optional, if you choose to do it, you must do this before moving to the next step. For more information see Configuring the update. The MRL_Update_Configurationfile.xml is located here: D:\TC_Kits\TC2606\wntx64\advanced_installations\resource_management\MRL\conf"

Select Compare your hierarchy to new class hierarchy. This step compares the exported hierarchies to the corresponding hierarchy in the newest MRL kit.

Click Next. Teamcenter displays the MRL Update Class Hierarchy for Modules dialog box, which contains only the hierarchies that you exported.

Select the hierarchies that you want to update and click Next.

Confirm your selections and click Next. Teamcenter compares the selected hierarchies to the ones in the EXPORT directory and creates individual update scripts with detailed information about what has changed in the hierarchies. The scripts are stored in a new UPDATE directory in the update directory that you specified. When complete, the installation wizard returns to the MRL Update Type Selection dialog box.

Select Update to new class hierarchy. This step updates the hierarchies that you compared to the new hierarchies in the MRL kit.

Click Next. Teamcenter displays the MRL Update Class Hierarchy for Modules dialog box, which contains only the hierarchies that you compared.

Select the hierarchies that you want to update and click Next.

Confirm that all your selections are correct and then click Next. Warning The update requires an extended period of time. The length of time required depends on the performance of your hardware. Upgrading the tool classification hierarchy can take up to 20 hours.

Teamcenter does the following during the update:

Adds new classes to the hierarchy

Adds new attributes to classes in the hierarchy

Updates class images and hierarchy icons

  1. If necessary, remove obsolete classes manually.
