Any version of CFMX...waiting for confirmation on whether it can be done in Pro...I think so....

Is this with CFMX for JRUN4 (currently in Beta)?

Check this out: http://livedocs.macromedia.com/jrun4docs/JRun_Administrators_Guide/clust erin g2.jsp#1113343 (watch for url wrapping) This applies to CFMX since it runs on JRun4...and we're using it now. In short, you specify a list of "buddy" servers running in the cluster and CMFX will handle automatic session sync'ing with the other machines. Here's a snippet of what to edit in the xml properties file: <session-config> <persistence-config> <active>true</active> <persistence-type>file</persistence-type> <persistence-synchronized>true</persistence-synchronized> <class-change-option>reload</class-change-option> <session-swapping>true</session-swapping> <session-swap-interval>5</session-swap-interval> <session-max-resident>500</session-max-resident> <replication-config> <active>true</active> <buddy-list>jrunserver2</buddy-list> <buddy-list>jrunserver3</buddy-list> <buddy-list>jrunserver4</buddy-list> </replication-config> </persistence-config> .... That should do it! -----Original Message----- From: Joe Eugene [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 25, 2002 1:58 PM To: CF-Talk Subject: Re: Measuring session scope impact on memory? Stacy, This is great info.. can you please explain on... "CFMX is cool because you can easily load balance the session data across a cluster just by editing a server buddy list!" How do you go about doing this?
