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:

Component	Effect
Portal	Object editors are either not available at all or have limited functionality. 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, error messages appear when you attempt to call functions that are not available.
Collaboration	You cannot create new rooms, or edit or delete existing rooms.
User Management Engine	You cannot create portal roles, but you can create and change UME roles 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.

You do not set write-protect mode from the PCD configuration file PCDStartup.Properties; rather, you set it from 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 set to false.

                            b.      Pcd.Pl.WriteProtectCause describes the reason that write-protect mode is activated. This information appears in the log files.

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

       4.      Click Update and then click Save.

A confirmation dialog box opens.

       5.      To apply the changes to all cluster elements, click Yes.

       6.      To reset the default values, click the Reset Default Global Properties icon.

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

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