How to Register and Configure HA for JD Edwards EnterpriseOne Enterprise Server as a Multi-Master Data Service

Language:

Before You Begin

Use this procedure to configure HA for JD Edwards EnterpriseOne Enterprise Server in a multi-master configuration. The following steps assume that you are using the configuration that is described in Multi-Master Configuration and have configured the server as described in Installing and Configuring JD Edwards EnterpriseOne Enterprise Server Software. If you are planning a different configuration, you must configure the JD Edwards EnterpriseOne Enterprise Server resources accordingly.

Add the HA for JD Edwards EnterpriseOne Enterprise Server resource type.
```
# clresourcetype register ORCL.JDE_Enterprise_Server
```

Create a scalable resource group for the JD Edwards EnterpriseOne Enterprise Server.
```
# clresourcegroup create -p  Maximum_primaries=m \
-p Desired_primaries=n jde-ent-svr-rg
```
–p Maximum_primaries=m

Specifies the maximum number of active primary nodes permitted for this resource group. The default is one.

–p Desired_primaries=n

Specifies the desired number of active primary nodes permitted for this resource group. The default is one.

jde-ent-svr-rg

Specifies the resource group name.

Bring the resource group online.

# clresourcegroup online -eM jde-ent-svr-rg

Create a multi-master resource to start the JD Edwards EnterpriseOne Enterprise Server instances simultaneously.
The following example starts the JD Edwards EnterpriseOne Enterprise Server instances on node1 and node2.

Set the JDE_USER and JDE_HOME properties with the JD Edwards EnterpriseOne Enterprise Server installation username and installation directory, respectively, for each node.

Set the Resource_dependencies_offline_restart property with the name of the SUNW.ScalMountPoint or SUNW.HAStoragePlus storage resource you are using.
```
# clresource create -t ORCL.JDE_Enterprise_Server -g jde-ent-svr-rg \
-p JDE_USER{node1}=jde-user \
-p JDE_USER{node2}=jde-user2 \
-p JDE_HOME{node1}=jde-home-directory \
-p JDE_HOME{node2}=jde-home-directory \
-p Resource_dependencies=logicalhost-n1-rs@node1,logicalhost-n2-rs@node2,db-instance-resource \
-p Resource_dependencies_offline_restart=jde-ent-hasp-rs \
jde-ent-svr-rs
```
Tip - You can create the resource in the global cluster or in a zone cluster. To create a resource in the specific zone cluster from the global cluster, use the –Z option to specify the name of the zone cluster.

Example 3 Configuring HA for JD Edwards EnterpriseOne Enterprise Server as a Multi-Master Service

This example uses the following sample component names:

Node names: node1, node2
Logical hostnames: logicalhost-n1, logicalhost-n2
Resource groups:
- logicalhost-n1-rg (for the logicalhost-n1-rs resource)
- logicalhost-n2-rg (for the logicalhost-n2-rs resource)
- jde-ent-hasp-rg (for the scalable HAStoragePlus resource)
- jde-ent-svr-rg (for the JD Edwards EnterpriseOne Enterprise Server resource)
Resources:
- logicalhost-n1-rslogicalhost-n2-rs (logical hostname resources)
- jde-ent-hasp-rs (scalable HAStoragePlus resource)
- jde-ent-svr-rs (multi-master JD Edwards EnterpriseOne Enterprise Server resource)
JD Edwards EnterpriseOne Enterprise Server instance 1 installation directory: /global/jde/u01 Username: jde910
JD Edwards EnterpriseOne Enterprise Server instance 2 installation directory: /global/jde/u02 Username: jde2910

Create failover resource groups to contain logical hostnames for
JD Edwards EnterpriseOne Enterprise Server instances
# clresourcegroup create -p Nodelist=node1,node2 logicalhost-n1-rg
# clresourcegroup create -p Nodelist=node2,node1 logicalhost-n2-rg

Add the logical hostname resources to the failover 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

Bring the logical hostname resource groups online
# clresourcegroup online -eM logicalhost-n1-rg
# clresourcegroup online -eM logicalhost-n2-rg

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

Add a scalable resource group for HAStoragePlus resource
# clresourcegroup create -p Maximum_primaries=2 \
-p Desired_primaries=2 \
jde-ent-hasp-rg

Register the resource type for HAStoragePlus resource
# clresourcetype register SUNW.HAStoragePlus

Add an HAStoragePlus resource to the jde-ent-hasp-rg resource group
# clresource create -g jde-ent-hasp-rg -t SUNW.HAStoragePlus \
-p FileSystemMountPoints=/global/jde affinityon=false jde-ent-hasp-rs

Bring the HAStoragePlus resource group online
# clresourcegroup online -eM jde-ent-hasp-rg

Create a scalable resource group for JD Edwards EnterpriseOne Enterprise Server resource
# clresourcegroup creare -p Maximum_primaries=2 -p Desired_primaries=2 jde-ent-svr-rg

Add a multi-master resource for JD Edwards EnterpriseOne Enterprise Server instances
# clresource create -t ORCL.JDE_Enterprise_Server -g jde-ent-svr-rg \
-p JDE_USER{node1}=jde910 \
-p JDE_USER{node2}=jde2910 \
-p JDE_HOME{node1}=/global/jde/u01/jdedwardsppack \
-p JDE_HOME{node2}=/global/jde/u02/jdedwardsppack \
-p Resource_dependencies=logicalhost-n1-rs@node1,logicalhost-n2-rs@node2,db-instance-resource \
-p Resource_dependencies_offline_restart=jde-ent-hasp-rs jde-ent-svr-rs

Bring the resource group online
# clresourcegroup online -eM jde-ent-svr-rg
