Client and Target Applications
This section describes some of the client and target application options
and processes. Target applications can be written using the EMS API.
EMS with ServiceGuard
ServiceGuard can be configured with EMS to monitor the health of
selected resources, such as disks. Based on the status of the resources,
ServiceGuard can decide to fail packages over. When working with EMS,
ServiceGuard acts as both the client and target application. EMS works
with MC/ServiceGuard and ServiceGuard Extension for RAC.
Configure EMS requests for use with ServiceGuard packages by editing
the package configuration ASCII file.
In addition, it is recommended that you also create requests through
EMS to:
• Enable a redundant notification system
• Monitor events that affect high availability
• Enable alerts due to a package failover
ServiceGuard may already be configured to monitor the health of nodes,
services, and subnets, and to make failover decisions based on the status
of these resources. Using EMS with ServiceGuard adds to the set of
failures or events that trigger failover and affect availability.
EMS GUI Client Application
The EMS GUI client application available in the Resource Management
area of HP SMH (HP System Management Homepage, earlier SAM) is used
to create monitoring requests for resources and targets. The EMS GUI
starts from the graphical version of HP SMH. Click through and select
from the various screens to define your monitoring request. The options
include the following:
1. Select the resources to be monitored.
