6.9 Precautions to be taken when using database session failover functionality

This section describes the points to be considered when using the database session failover functionality.

• If you operate the contents of tables used in the database session failover functionality, you cannot correctly keep the system information and hence you cannot continue the normal operation.

  You can execute only the following operations as the operations that accompany changes made in the tables in a database, which are to be used in the database session failover functionality. Even when executing the following operations, follow the procedures described in reference locations.

  • Changing settings of the database session failover functionality (see 6.7)

  • Initializing a table (see 6.7.2)

  • Destroying an HTTP session (see 6.7.3)

  Do not execute any other operations.

• If the size of HTTP session attribute information exceeds maximum size, the information of the HTTP session is not replicated in the database.
