在Oracle中,可以通过以下步骤来实现连接池和连接重用:
EXEC DBMS_CONNECTION_POOL.CREATE_POOL(pool_name => 'MY_CONNECTION_POOL', maxsize => 10, minsize => 2, incrsize => 1, session_state => 'ACTIVATED');
DECLARE
conn UTL_TCP.connection;
BEGIN
conn := DBMS_CONNECTION_POOL.ACQUIRE_CONNECTION(pool_name => 'MY_CONNECTION_POOL');
END;
DECLARE
conn UTL_TCP.connection;
BEGIN
conn := DBMS_CONNECTION_POOL.ACQUIRE_CONNECTION(pool_name => 'MY_CONNECTION_POOL');
-- 使用连接
...
DBMS_CONNECTION_POOL.RELEASE_CONNECTION(conn);
END;
通过以上步骤,可以在Oracle中实现连接池和连接重用,从而提高应用程序的性能和可伸缩性。
