Element Description Key Considerations
secondary_server The name of the HDR secondary server to connect to. The name must be defined in the DBSERVERNAME or DBSERVERALIASES configuration parameter, or as an Enterprise Replication group name.

Usage

Run this function on a standard server to convert it to an HDR primary server and connect to the specified HDR secondary server. If the connection is successful, replication begins.

This function is equivalent to the onmode -d primary command.

Example

The following example converts a standard server named ids_stores to an HDR primary server:
EXECUTE FUNCTION task("ha set primary","ids_stores");
