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
- Analyze your environment to identify all the potential
points of failure.
- Review the documentation for the components you want to
configure.
- 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.
- Install any additional hardware components to increase
the number of nodes in your high availability topology.
- 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.
- Optional: Install System
Automation for Multiplatforms on
all nodes.
