Ensure DISCOVER is set to DISABLE

低等級 2自動化db2

說明

DISCOVER=SEARCH lets the instance answer network discovery requests, advertising instances and databases to anyone on the network. Run as the instance owner (or with sqllib/db2profile sourced) so 'db2 get dbm cfg' reads the instance configuration.

預期輸出: compliant
