Prerequisites

It is assumed that you have installed Oracle Coherence Cloud and created a stack comprising compute instance(s), using the Oracle Cloud Infrastructure Marketplace.

Before you begin scaling out your Coherence cluster, complete the prerequisite steps:

1. Sign in to the Oracle Cloud Infrastructure Console.
2. Click the navigation menu, select Compute, and then select Instances.
3. Click the name of your Coherence server instance(s).
4. From the Instance Details page, make a note of the following:
   • The name of the installed Virtual Cloud Network (VCN)
   • The name of the installed subnet, subnet type, and subnet span
5. Save a copy of the operational override file associated with your existing node:
   1. Using SSH, log in to the public IP address of one of the nodes as the opc user. Then, switch to the oracle user by running the sudo su - oracle command.
   2. In your current node, open the /opt/usr/local/etc/ directory and save a copy of the coh_operational_override.xml file.
