Enabling Availability for a Server Instance

To enable availability for a server instance, use the asadmin set command to set the configuration’s availability-service.availability-enabled property to true.

For example, if config1 is the configuration name:

asadmin set --user admin --passwordfile password.txt 
--host localhost 
--port 4849 
config1.availability-service.availability-enabled="true"

To Enable Availability for the Server Instance with Admin Console

1. In the tree component, expand the Configurations node.

2. Expand the node for the configuration you want to edit.

3. Select the Availability Service node.

4. In the Availability Service page, enable instance level availability by checking the Availability Service box.

   To disable it, uncheck the box.

   Additionally, you can change the Store Pool Name if you changed the JDBC resource used for connections to the HADB for session persistence. For details, see configure-ha-cluster(1).
