Load Management

Load Management

If you install a Data Vault Service agent on the failover server to improve query processing, you can set the priority for the Data Vault Service agents in the primary and failover servers to balance the processing load.
Set the priority level of an agent to make the most efficient use of the nodes in the cluster server. For example, you might set the agents that are hosted on a more powerful machine to a higher priority so that they perform most of the processing.
You can use the Data Vault Service Administrator tool or the command line program to set the agent priority level. To set the priority level on the command line, run the following Data Vault Service administration command:
Priority <host-name> <agent-ID> <priority-level>
To set the priority level of multiple agents in the primary and failover servers, you can create a script to run the priority command for each agent. For example, you can run the following script:
echo 'agents' | ssaadmin DBA | awk '($4 == "READY") { TAB[$1] += 1; print "priority " $1 " " $2 " " 100 - TAB[$1] }' | ssaadmin DBA
This script sets the priority for each agent that runs on the server cluster and displays the list of agents and priorities.
