Re: Urgent : Problems using the 'Shared File System Master Slave' featur

["eric.renault" <er...@gmail.com>]

Hello again
I forgot to mention that I am using the SAN between 4 boxes.
L'et's call them Server1, Server2, Server3 and Server4.
They all share the "/vol03" dir via the disk array.
BrokerA is started on Server1
BrokerAbck is started on Server2
...etc

By the way I noticed sth odd :
removing these 2 properties : 'journalLogFiles="5" useJournal="true"' make
the broker unable to start...

Please Help
