2.5.2.2 Assumptions

This section assumes the following to be true:

• A Load Balancer (software or hardware) is identified andinstalled.
• An appropriate backup strategy for OFSAA File System ($FIC_HOMEand FTPSHARE) and Oracle Database (or Databases) is (or are) already installed andconfigured.
• Installation of the OFSAA platform and applications on the primary node is completed andsetup is working.
• A secondary instance (node) for OFSAA is identified and configured withappropriate prerequisite software. No installation of OFSAA products is required at this stage.
• Hardware configurations (in terms of RAM, CPU, and CORE) do not vary between theOFSAA primary and secondary nodes.
• It is also mandatory that the file system references such as the OS mount and directories, web application server pro files, domains, deployed paths, and so on are the same between the primary and secondary nodes.

The following are the assumptions for HA configuration in OFSAA.

• The Global Load Balancer (or Balancers) is (or are) installed and any post-installation configuration (hardening) is completed before beginning with the following steps. If noload balancer is installed, you can install and configure it on any host at this time.
• The OFSAA primary node installation was not performed keeping in mind the HAarchitecture. That is, multiple HTTP Servers, Web Application Server cluster nodes, DB RAC cluster nodes, common file storage (FTPSHARE), and so on are not set up.
• The OFSAA primary node installation was performed using the local IP address orHostname.
