在Oracle中,可以通過以下步驟來實(shí)現(xiàn)連接池和連接重用:
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');
-- 使用連接
...
DBMS_CONNECTION_POOL.RELEASE_CONNECTION(conn);
END;
通過以上步驟,可以在Oracle中實(shí)現(xiàn)連接池和連接重用,從而提高應(yīng)用程序的性能和可伸縮性。
