DQP_ENABLED Option
Temporary database option DQP_ENABLED allows you to enable or disable distributed query processing at the connection level.
ON, OFF
ON
Option can be set at the database (PUBLIC) or user level. At the database level, the value becomes the default for any new user, but has no impact on existing users. At the user level, overrides the PUBLIC value for that user only. No system privilege is required to set option for self. System privilege is required to set at database level or at user level for any user other than self.
Requires the SET ANY PUBLIC OPTION system privilege to set this option. Can be set temporary for an individual connection or for the PUBLIC role. Takes effect immediately.
You can set the temporary database option DQP_ENABLED to OFF to disable DQP for the current connection. You can set the option to ON (the default value) to enable DQP for the current connection, but only when DQP is enabled for the user by that user's login policy for the logical server of the current connection.
Setting DQP_ENABLED to ON results in an error if DQP is disabled based upon the user's login policy:
Invalid setting for option 'DQP_ENABLED'
Any changes you make to a user's login policy options affect new connections only. Login policy option settings for existing connections are based upon the time the connection was initially established.
