WARNING: Subscription for node down event still pending

做dataguard时出现的错误提示

1) Rename the Oracle10g ons.config file so the listener does not find or use it.

cd $ORACLE_HOME/opmn/conf

mv ons.config ons.config.orig

(then restart the listener)

2) Explicitly disable the 10g TNS Listener from subscribing to the ONS.

Edit the active 10g listener.ora file and add the parameter below:

SUBSCRIBE_FOR_NODE_DOWN_EVENT_<listener_name>=OFF

where <listener_name> would be replaced with the actual listener name configured in the listener.ora file.

For example, if the listener name is LISTENER (default), the parameter would be:

SUBSCRIBE_FOR_NODE_DOWN_EVENT_LISTENER=OFF

(then restart the listener)
