► Application
Configuration at this level is applied to all Web modules within the application.
Navigate to Applications → Application Types → WebSphere enterprise
applications → → Session management → Distributed
environment settings → Memory-to-memory replication.
► Web module
Configuration at this level is applied only to that Web module. Navigate to
Applications → Application Types → WebSphere enterprise
applications → → Manage modules → →
Session management → Distributed environment settings →
Memory-to-memory replication.
The following session management properties can be set:
► Session tracking mechanism
Session tracking mechanism lets you select from cookies, URL rewriting, and SSL
ID tracking. Selecting cookies will lead you to a second configuration page
containing further configuration options.
► Maximum in-memory session count
Select Maximum in-memory session count and whether to allow this number to be
exceeded, or overflow.
► Session time-out
Session time-out specifies the amount of time to allow a session to remain idle
before invalidation.
► Security integration
Security integration specifies a user ID be associated with the HTTP session.
► Serialize session access
Serialize session access determines if concurrent session access in a given
server is allowed.
► Overwrite session management
Overwrite session management, for enterprise application and Web module level
only, determines whether these session management settings are used for the
current module, or if the settings are used from the parent object.
► Distributed environment settings
Distributed environment settings select how to persist sessions
(memory-to-memory replication or a database) and set tuning properties.
Note: Memory-to-memory persistence is only available in a Network Deployment
distributed server environment.
