services to LAN attached clients.
MC/ServiceGuard monitors the health of various components within each node and quickly responds to
failures in a way that eliminates or minimizes application downtime. MC/ServiceGuard is able to detect
and respond to failures in:
System and application processes
LAN media and adapters
Storage sub-system and adapters
For ease of management and outstanding flexibility MC/ServiceGuard for Linux allows all of the resources
needed by an application to be organized into entities called "application packages". Application packages
consist of any resource needed to support a specific application service such as disks, network resources,
and application or system processes. Packages are the entities that are managed and moved within the
MC/ServiceGuard for Linux is an important component in creating a complete and robust environment for
highly available mission critical applications. In order to create a complete solution, the application
environment should be designed to eliminate all single points of failure and to minimize the impact of
various component failures.
The memory requirement for MC/ServiceGuard for Linux depends on the number of packages configured
in the cluster. The following equation provides a rough estimate of how much lockable memory is needed:
Total Memory = 6 MB + 80KB/package in cluster
The total amount is needed on all nodes in the cluster, regardless of whether a given package or resource is
on that node or not.
