This example shows how to install a dual stack with enqueue replication on a two-node cluster consisting of the nodes pbono1 and pbono2.
In this example, the primary application instance is installed in a failover resource group. Two additional dialog instances are deployed on the physical hosts, pbono1 and pbono2, in a multiple-master resource group.
Pick a database that can be made highly available. Depending on your choice, you might need a different resource group layout for the database.
The enqueue server to be configured is of type enqueue server version one.
The logical hosts are as follows:
bono1 — Central services
bono2 — Database
bono3 — Replicated enqueue server
bono4 — Primary application instance
The following instance numbers will be installed.
00 — Central services for ABAP
01 — Central services for Java
10 — Replicated enqueue server ABAP
11 — Replicated enqueue server Java
02 — Primary application instance
03 — Additional dialogue instance on pbono1
04 — Additional dialogue instance on pbono2
You need the following resource groups:
Database — db-rg (failover)
Central services — scs-rg (failover/positive affinity for rep-rg)
Replicated enqueue services — rep-rg (failover)
Primary application instance — pas-rg (failover)
Additional application instance — dia-rg (multiple masters)
