High Availability Installation
Before installing CA Identity Manager, consider what your goals are. For example, you may want a resilient implementation that consistently provides good performance. You may also want to make the implementation scalable, so you can easily add users and systems over many different network operating systems, security systems, databases, and groupware products.
A high-availability implementation provides the following features:
- Failover—Switches to another system automatically if the primary system fails or is temporarily offline for any reason
- Load balancing—Distributes processing and communications activity evenly across a computer network so that performance remains good and no single device is overwhelmed
- Various deployment tiers that provide the flexibility to serve dynamic business requirements
A high-availability implementation addresses the following requirements:
- The Identity Manager Server can be installed on an application server to allow failover to any of the nodes in the cluster, providing uninterrupted access to users.
- The Provisioning Directory uses a CA Directory router to route Provisioning Server directory traffic using the X.500 protocol.
- CA Identity Manager includes the connector servers that can be configured per-directory or per-managed systems. Installing multiple connector servers increases resilience. Each connector server is also an LDAP server, similar to the Provisioning Server.
