How to Prepare the Nodes for a Multi-Master Configuration

Use this procedure to prepare for the installation and configuration of HA for JD Edwards EnterpriseOne Enterprise Server in a multi-master configuration.

This procedure assume two nodes in the cluster and implements the configuration shown in HA for JD Edwards EnterpriseOne Enterprise Server in a Multi-Master Configuration Using a Scalable Resource Group.

Before You Begin

Ensure that the /etc/netmasks file has IP-address subnet and netmask entries for all logical hostnames. If necessary, edit the /etc/netmasks file to add any missing entries.

1. Create failover resource groups for the logical hostname for the HA for JD Edwards EnterpriseOne Enterprise Server resources.

   # clresourcegroup create -p Nodelist=node1,node2 logicalhost-n1-rg
   # clresourcegroup create -p Nodelist=node2,node1 logicalhost-n2-rg

2. Create logical hostname resources in the resource groups.

   # clreslogicalhostname create -g logicalhost-n1-rg -h logicalhost-n1 logicalhost-n1-rs
   # clreslogicalhostname create -g logicalhost-n2-rg -h logicalhost-n2 logicalhost-n2-rs

3. Bring the logical hostname resource groups online.

   # clresourcegroup online -eM logicalhost-n1-rg
   # clresourcegroup online -eM logicalhost-n2-rg

4. Set the Failback property for each logical hostname resource group.

   # clresourcegroup set -p Failback=TRUE logicalhost-n1-rg
   # clresourcegroup set -p Failback=TRUE logicalhost-n2-rg

5. Configure a cluster file system to be managed by an HAStoragePlus resource in a scalable resource group.

   For more information, see How to Set Up the HAStoragePlus Resource Type for New Resources in Oracle Solaris Cluster 4.3 Data Services Planning and Administration Guide.

   1. Create a scalable resource group.

      The optional -n nodelist specifies where the JD Edwards EnterpriseOne Enterprise Server instances can be brought online.

      # clresourcegroup create -p Maximum_primaries=maximum-number-active-primaries \
      -p Desired_primaries=number-active-primaries \
      [-n nodelist] jde-ent-hasp-rg

      See the clresourcegroup(1CL) man page for information about clresourcegroup options and properties.

   2. Register the SUNW.HAStoragePlus resource type.

      # clresourcetype register SUNW.HAStoragePlus

   3. Create an HAStoragePlus resource.

      Specify the value of the FileSystemMountPoints property as follows:

      • If you installed the JD Edwards EnterpriseOne Enterprise Server instances on separate directories under the same mount point, specify only that one mount point.

      • If you installed each JD Edwards EnterpriseOne Enterprise Server instance on a separate mount point, specify a comma-separated list of all the mount points.

      # clresource create -g jde-ent-hasp-rg \
      -t SUNW.HAStoragePlus \
      -p FileSystemMountPoints=mount-point \
      -p AffinityOn=false jde-ent-hasp-rs

      See the SUNW.HAStoragePlus(5) man page for more information about SUNW.HAStoragePlus resource type properties.

   4. Bring online the resource group.

      clresourcegroup online -eM jde-ent-hasp-rg
