    Singleton Failover

    Terry Chan Newbie

      I have a jboss cluster with 2 members. The OS is Redhat Linux Advanced Server 4 and the jboss version is 3.2.5. There are 3 singletons being put in deploy-hasingleton folder in each member. I want to test the singleton failover in this cluster and 2 cases are observed:

      1) In the master node, I use the command "ps -auxwww | grep run.sh' to kill the jboss service, the 3 singletons can be launched in the 2nd node within 2 minutes and it is acceptable for us.

      2) In the master node, I quit the jboss service using normal exit, i.e."Ctrl-C". However, the 3 singletons can also be launched in the 2nd node but it almost needs 10 - 15 minutes to complete the launching process. I tried to decrease the value of the linux kernel parameters like /proc/sys/net/ipv4/tcp_rmem or /proc/sys/net/ipv4/tcp_wmem or /proc/sys/net/ipv4/tcp_retries2, but none of them help.

      Please give an advice on tackling the 2nd case timing issue.
