In 1-to-1 node switching systems, mutual node switching systems, and node switching systems for the host unit management model, Application Server related processes cannot be started in Application Server of the standby node. Therefore, note that you cannot execute the following operations:

• Deploying and undeploying applications in the J2EE server
  Includes replacing J2EE applications
  
• Management operations by the Management Server and the Administration Agent

Also, you cannot access a shared disk device from Application Server of the standby node. When J2EE servers are used and when there is a global transaction, the definition information of the transaction service is stored in the shared disk device. However, you cannot change this definition information from Application Server of the standby node.
