Setting Write-Protect Mode for the PCD 

Use

You can prevent data from being written to the Portal Content Directory (PCD) by activating write-protect mode. For example, you can activate write-protect mode when migrating data from an old portal system to a new one in order to prevent data from being written to the old system during this time.

The following components are affected by write-protect mode:

·        Portal

The editors are either not available at all or only have limited functionality in the portal. For example, portal administrators cannot import or export packages using the Package Transport Editor. They also cannot create new objects, delete objects, or edit objects using the object editors. Personalization of the portal themes is not available. When the portal is in write-protect mode, the corresponding error messages appear when you call functions that are currently not available in the portal.

·        Collaboration

You cannot create new rooms or edit or delete existing rooms.

·        User Management Engine

Portal roles cannot be created, but UME roles can still be created and changed since they are not stored in the PCD. You cannot assign portal roles to actions, neither in the user management administration console nor in the Role Editor.

Note that write-protect mode is not set from the PCD configuration file PCDStartup.Properties; rather, it is set within the service configuration of the Visual Administrator.

Procedure

...

       1.      Start the Visual Administrator.

       2.      Choose Global Configuration ® Server ® Services ® com.sap.portal.pcd.gl.

The properties of the service are displayed:

                            a.      Pcd.Pl.WriteProtectActivated defines whether or not write-protect mode is activated. By default it is not activated (value = false).

                            b.      Pcd.Pl.WriteProtectCause contains an explanation why write-protect mode is activated. This information appears in the log files, for example.

       3.      Activate write-protect mode by entering true as the value for Pcd.Pl.WriteProtectActivated. Then click on Update.

       4.      Click on the icon for saving. A dialog box appears. To apply the changes to all cluster elements, click on yes.
A second dialog box appears. To start the service again, click again on yes.

       5.      If you want to reset the default values, click on the icon for resetting the Default Global Properties.

Write-protect mode can only be configured for the entire cluster. You should therefore perform the configuration in the Global Configuration of the Visual Administrator. Local server configurations are ignored.

It is not necessary to switch on write-protect mode in order to create an online backup. For more information about online backup, see Note 779708.
