Failover Mechanisms

As part of your implementation, you can perform the following tasks to provide failover mechanisms:

Deploy CA Service Catalog in a cluster.
If you use CA Workflow, Deploy CA Workflow in a cluster.
If you use CA Process Automation, deploy clustering in CA Process Automation.
Use database clusters. CA Service Catalog components are also compatible with database clusters which are recommended for environments experiencing heavy load.
Note: For information about database clustering, see your DBMS documentation.
Use a load balancer. Clustering requires a load balancer. To maximize the uptime of CA Service Catalog, include the load balancer and cluster computers in your failover plan.
Implement clustering on the load balancer computer.
Move user-generated files from the local file system to a filestore (a central location) on a high-availability network shared file system. Catalog maintains several user-generated files on the local file system. These files include forms and XSL and XML customizations.
If you are using CA EEM for authentication, cluster CA EEM, using operating system level clustering.
Note: For information about clustering and implementing failover with CA EEM, see your CA EEM documentation.
Improve the robustness of the hardware used in your environment, by using all applicable means, including RAID hard disks, redundant power supply, and network cards.
Note: For information about using these means, see your hardware documentation.
