Discovering and hiding server instances and databases

You might have multiple instances, and multiple databases within these instances, on a server system. You might want to hide some of these from the Discovery process.

Procedure

  • To allow clients to discover server instances on a system, set the discover_inst database manager configuration parameter in each server instance on the system to ENABLE (this is the default value).

    Set this parameter to DISABLE to hide this instance and its databases from Discovery.

  • To allow a database to be discovered from a client, set the discover_db database configuration parameter to ENABLE (this is the default value).

    Set this parameter to DISABLE to hide the database from Discovery.

    Note: If you want an instance to be discovered, discover must also be set to KNOWN or SEARCH in the DAS configuration file.
    Note: If you want a database to be discovered, the discover_inst parameter must also be enabled in the server instance.
