established previously for the local user session. The connections and sessions established to remote how to use dblink in oracle procedure databases persist for the duration of the local user's session, unless the application or user explicitly terminates them. Note that when you https://asktom.oracle.com/pls/apex/f?p=100:11:0::NO::P11_QUESTION_ID:456820211101 issue a SELECT statement across a database link, a transaction lock is placed on the undo segments. To rerelease the segment, you must issue a COMMIT or ROLLBACK statement. Terminating remote connections established using database links is useful for disconnecting high cost connections that are no https://docs.oracle.com/cd/B28359_01/server.111/b28310/ds_appdev002.htm longer required by the application. You can terminate a remote connection and session using the ALTER SESSION statement with the CLOSE DATABASE LINK clause. For example, assume you issue the following transactions: SELECT * FROM emp@sales; COMMIT; The following statement terminates the session in the remote database pointed to by the sales database link: ALTER SESSION CLOSE DATABASE LINK sales; To close a database link connection in your user session, you must have the ALTER SESSION system privilege. Note: Before closing a database link, first close all cursors that use the link and then end your current transaction if it uses the link.
