CA AppLogic is a self-healing grid operating system which improves the availability of applications and services. High-availability refers to a set of features which together provide:
One of the most important features of high-availability is the automated application/grid recovery from various types of failures. For applications, automated recovery is provided for appliances that may fail due to either appliance software failure or server failure (either physical server failure or a software bug that leads to a server failure). In addition, a grid is able to tolerate failures of its grid controller. If the grid controller fails, it is either restarted on the same server (if possible) or a different server while minimizing the impact on running applications.
CA AppLogic also proactively detects various types of issues and alerts the user before those issues can cause application or grid failures/downtime.
The following types of problems are automatically detected:
The following sections describe the high availability features in more detail. Information is also included regarding the effects of various failures on the applications/grid and what a user may experience during such failures.
This section contains the following topics:
