Oracle
IMPORTANT NOTE: The pages on this site assume that all steps documented are performed (unless specifically marked as optional). Other pages assume that the configuration from predecessor pages is in place. E.g. the page on the Oracle Listener assumes that the LISTENER_NAME environment variable is set in the .profile as documented on the Oracle Install page and the Data Guard documentation assumes that LOCAL_LISTENER has been set as recommended.
