Article ID: KB31228 KB Last Updated: 27 Aug 2020Version: 4.0
Summary:

This article explains how to properly restart JBOSS services.

Solution:

First, identify which node has the vip (eth0:0).  Check each node with the following:

# ifconfig eth0:0
 
Recommended restart process (only if JBOSS restart is needed):
  1. Stop processes on all JBOSS nodes
    Note: For Multiple Jboss nodes, it does not matter the order each node is stopped in. Though stopping the VIP node last may slightly speed up stop time.

    # service jmp-watchdog stop
    # service jboss stop
    # service jboss-dc stop

    Note: jboss-dc is only active on VIP node, but the command won't do any harm

  2. Confirm if JBOSS has been turned off  (all jboss nodes)

    # service jboss status
  3. Start services on the VIP node ONLY

    # service jmp-watchdog start

    Note: watchdog starts other processes

  4. After you can login to the Space WebUI, and after Schema has finished loading, Administration, Fabric node status. Start services on all of the other nodes

    # service jmp-watchdog start
Note: While you can start additional nodes prior to being able to login to Space webUI, JTAC recommends waiting for the first node to be 100% ready to work prior to starting other nodes.
