I have just tested this high availability feature and once the mysql backend changes over, our threads in the connection pool are all gone.  These threads do not recover unless we restart JBoss which defeats the purpose of high availability. Is there a setting in a datasource file that I can add ? Our datasource file only have these two connection pool settings: |     | <min-pool-size>10</min-pool-size> | | | <max-pool-size>100</max-pool-size> | Hope this is enough info I'm quite new to java technologies. Thanks, -ck -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/733091#733091] Start a new discussion in Datasource Configuration at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
