Any idea why the session does not get persisted to the database
immediately (when setting maxIdleSwap='0'). Or is there any other
possible way to "Always Load" and "Always Save Sessions" from the
database in Tomcat 6

Thanks Mark for the quick response.
I just tried what you mentioned setting maxIdleSwap='0'. But for some
reason the session does not get persisted to the database immediately.
It takes around 30 sec for it to happen . Any other setting I need to
add inorder that it saves immediately so that i can safely use it in a
non-sticky session environment.
Ive added a snippet of the server.xml for your reference :
<Manager className="org.apache.catalina.session.PersistentManager"
maxIdleSwap='0'>
<Store className="org.apache.catalina.session.JDBCStore"
connectionURL="jdbc:mysql://172.16.142.163:3306/session2?user=user&password=password"
driverName="com.mysql.jdbc.Driver"
sessionAppCol="app_name"
sessionDataCol="session_data"
sessionIdCol="session_id"
sessionLastAccessedCol="last_access"
sessionMaxInactiveCol="max_inactive"
sessionTable="tomcat_sessions"
sessionValidCol="valid_session" />
</Manager>
Thanks

Hey,
Im am migrating my webapp from Resin to Tomcat 6. In Resin there is an
option to "always save sessions" and "always load sessions" from the
persistent store (mysql db). Ive configured my tomcat instance to use
the JDBC for the persistence of sessions.
(http://tomcat.apache.org/tomcat-6.0-doc/config/manager.html ). But the
sessions are stored only when Tomcat shutsdown/restarts or if the idle
time has exceeded. There is no mention of how to "always save" and
"always load sessions" from the db.
My requirement is such that I want to run two standalone instances of
Tomcat (not using clustering) and for every request it loads the
session
from the database and saves it back.
Can you please tell me if this is possible in Tomcat . If yes, how.
