Third-Party Web Parts for SharePoint

SharePoint websites support third-party web parts. To ensure that web parts on the Master server are available to the SharePoint website on the Replica server, you must import the web parts to the Replica server after failover is complete.

CA ARCserve RHA SharePoint COM+ Service

When the CA ARCserve RHA Engine is installed in a SharePoint environment that is joined to a SharePoint farm, the installation process installs CA ARCserve RHA SharePoint COM+ and registers the corresponding service, CAARCserveRHASPSCOMApp, for all SharePoint Scenarios. When you uninstall the CA ARCserve RHA Engine, the uninstallation process uninstalls and unregisters the corresponding components.

On Windows Server 2008 systems, the Microsoft Distributed Transaction Coordinator (MSDTC) service may prevent the SharePoint COM+ application from starting properly. This may prevent SharePoint HA scenarios from performing critical operations. For example, database Auto-Discovery, Run this scenario, Assured Recovery (AR) testing, and so on. To remedy this problem, restart the server where the problem occurred (Master or Replica).

For server farms, change the logon account of the CA ARCserve RHA SharePoint COM+ service on the Master server to Domain Administrator after the service is installed to prevent some SharePoint HA operations from failing. The service logon account on the Replica is changed during auto-configuration.

During CA ARCserve RHA Engine upgrade, the COM+ service is removed with the previous version of the Engine. After the upgrade is finished and the Engine is restarted, you can automatically install and start the COM+ service, but the start-up account may be set to Local System instead of Domain Administrator, as configured before upgrade. You must manually configure the service to be Domain admin before you start a scenario.

During scenario creation, you are prompted to enter the Domain Administrator's account credentials for Replica auto-configuration. If you enter the wrong account and passphrase (SharePoint Server 2010), auto-configuration fails. Click Back in the Scenario Creation Wizard to try again.

Note: Auto-configuration changes the logon account of the SharePoint services on the Replica to the account you specify. If the logon accounts of SharePoint services on the Master are different, you must change the Replica account manually.
