EAServer Manager enhancements
In EAServer 5.2, EAServer Manager includes new configuration wizards for
these entity types:
• Log Profile
• Log Category
• Log Handler
• Log Formatter
EAServer Manager launches the wizard when you create an entity of the
associated type, instead of displaying a properties dialog box with default or
empty values. You can also reconfigure existing entities using the wizard. To
launch the wizard on an existing entity, highlight the entity’s icon and choose
File | Configuration Wizard. EAServer Manager continues to provide
properties dialogs for all these entities. For more information on the wizard
steps, see the EAServer Manager online help.
In-memory mirror caching
EAServer 5.2 provides in-memory mirror caching for objects saved in the
EAServer object cache. This allows objects to be accessed by any server in a
cluster, and offers better performance than persistent database caching. For a
new server that joins a mirror group or cluster, this feature provides in-memory
synchronization. You can use in-memory mirror caching for stateful session
components and HTTP sessions.
Mirror caching guarantees that:
• If a remote server in the current mirror group is not available, any object
can still be retrieved.
• Any object in the cache is in sync with the latest copy of the object in the
current mirror group, except when the originating server fails before
completing a
PUT operation on all servers in the group.
• A copy of an object being saved in the local cache is updated immediately
on all available servers in the current mirror group, except when the
originating server fails before completing a
PUT operation on all servers
in the group.
