Declare the database schema
The DB Sync client application must declare the database schema by registering a JSON
schema file using the dbsync_app.register_local_dbschema()
function.
The DB Sync client application code must declare the DB Sync schema by providing the schema file:
CALL dbsync_app.register_local_dbschema(schema_filename)
In this call, the schema_filename must be the JSON file containing the database schema definition. To create the schema file, see Set up the database schema file or Set up DB Sync in direct mode. The schema file must be deployed with application program files.
