This subsection describes the information that the standby node inherits and the information that the standby node does not inherit during node switching.
- Information that the standby node inherits
- Inheriting the OTS transaction information (in a global transaction)
After you switch from the executing node to the standby node, the standby node inherits the OTS transaction information and performs the transaction recovery process.
- Information that the standby node does not inherit
Note that when node switching occurs, the post-switching node does not inherit the following information:
- HTTP session information of the application that the Web container manages
- Attribute information set in ServletContext of the Web container
- Session information of the Bean of the home interface and component interface
- Information about the operation status of applications, and the status of JNDI cache, connection pool and CTM queue
