Brief preview of my lab environment how entire domain is setup.

  • Two manage servers “server1” and “server2” configure in a distributed manner.
  • server1 is configure on first machine host01 and server2 is configure on 2nd machine host02.   Both machines are configure to start mange server JVM’s using nodemanager  feature.

domain1

  • node manager is reachable on the first machine.

machine1

  • Node manager is configure on 2nd machine and it is reachable.

machine2

ENABLEING CRASH RECOVERY FEATURE

  • GO TO $DOMAIN_HOME/nodemanager  directory and look for a file with the name of nodemanager.properties
  • vi into this file and change to crashRecoveryEnabled=false to   crashRecoveryEnabled=true.
