Parallel installation

If you installed one cluster and want to install a second cluster in parallel with the first as a means of transitioning from the old cluster to the new cluster, you must make some changes after installing but before starting the second cluster.

Before you begin

You must have installed a second cluster to run in parallel with an original cluster, but you must not have started the second cluster yet.

Procedure

  1. Change the service start type from automatic to manual in the named.xml file, located in $EGO_CONFDIR/../../eservice/esc/conf/services.

    <sc:StartType>Manual</sc:StartType>

  2. Comment out the dependency on service director in the wsg.xml file, located in $EGO_CONFDIR/../../eservice/esc/conf/services.

    <!-- <sc:Dependency type="OnStart">ServiceDirector</sc:Dependency>

  3. Start the second cluster.
  4. When the first cluster is decommissioned, stop the WebServiceGateway service.
  5. Change the start type back to automatic in named.xml and uncomment the service director dependency in wsg.xml.
  6. Start the WebServiceGateway service.
