Interesting...I saw the option of buddy servers in the JRUN admin panel but didn't know you can just edit an XML props file to achieve the same thing for CFMX with the built-in JRUN. Can you point me in the direction of where to find that XML file? (file name, dir location)
Much appreciated!

Any version of CFMX...waiting for confirmation on whether it can be done in Pro...I think so.... -----Original Message----- From: Chris Kief [mailto:[EMAIL PROTECTED]] Sent: Thursday, July 25, 2002 3:03 PM To: CF-Talk Subject: RE: Measuring session scope impact on memory? 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?
