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...
