Using the VCS Engine Process
When the VCS engine process "had" becomes active on a system, it automatically starts the appropriate agent processes, based on the contents of the configuration files. A single VCS agent process monitors all resources of the same type on a system.
After the VCS engine process is active, type the following command at the system prompt to verify that the agent has been started and is running:
haagent -display resource_type
For example, to test the Oracle agent, type:
haagent -display Oracle
If the Oracle agent is running, the output resembles:
#Agent Attribute Value
Oracle AgentFile
Oracle Faults 0
Oracle Running Yes
Oracle Started Yes
Test Commands
The following examples show how VCS commands can be used to test the agent:
- To activate agent debug messages for C++ agents, type:
hatype -modify resource_type LogDbg -add DBG-AGINFO
- To check the status of a resource, type:
hares -display resource_name
- To bring a resource online, type:
hares -online resource_name -sys system
This causes the online entry point of the corresponding agent to be called.
- To take a resource offline, type:
hares -offline resource_name -sys system
This causes the offline entry point of the corresponding agent to be called.
- To deactivate agent debug messages for C++ agents, type:
hatype -modify resource_type LogDbg -delete DBG-AGINFO
