Prerequisites to configuring high availability

Before you can configure your system for high availability, you must complete a number of prerequisite tasks and determine the best approach for installing your product.

Procedure

  1. Analyze your environment to identify all the potential points of failure.
  2. Review the documentation for the components you want to configure.
  3. Contact your sales representative to find out the additional costs of your implementation. For example, your costs can be affected by adding additional nodes and purchasing licenses for products such as System Automation for Multiplatforms.
  4. Install any additional hardware components to increase the number of nodes in your high availability topology.
  5. Install the product:
    • If you are installing the product for the first time, you can elect to install and configure the middleware components before you install the product. However, for best results, install the product before configuring the components for high availability.
    • If you choose to implement high availability after the product is already installed, you must configure your environment to use the Service IPs that are associated with the highly available environment. For example, you update the database URL to point to the highly available database Service IP, and you update the application server security to point to the directory server Service IP.
    For detailed information about the installation procedure, see the Knowledge Center for your product.
  6. Optional: Install System Automation for Multiplatforms on all nodes.
