oci_set_module_name
(PHP 5 >= 5.3.2, PHP 7, PHP 8, PECL OCI8 >= 1.4.0)
oci_set_module_name — Sets the module name
說明
$connection, string $name): boolSets the module name for Oracle tracing.
The module name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.
The name can subsequently be queried from database administration
views such as V$SESSION. It can be used for
tracing and monitoring such as with V$SQLAREA
and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE.
The value may be retained across persistent connections.
參數
-
connection -
Oracle 連線標識，由 oci_connect()，oci_pconnect()，或 oci_new_connect() 返回。
-
name -
User chosen string up to 48 bytes long.
返回值
成功時返回 true， 或者在失敗時返回 false。
範例
示例 #1 Setting the module name
<?php
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the module
oci_set_module_name($c, 'Home Page');
// Code that causes a round-trip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the // modules in use: sqlplus system/welcome SQL> select module from v$session;
註釋
注意: Oracle 版本需求
當 PHP 是與 Oracle 數據庫 10g 及更新版本的 擴充套件庫鏈接時，此函式可用。
效能
使用舊版的 OCI8 或 ORACLE 數據庫，可使用
Oracle DBMS_APPLICATION_INFO 包來設定客戶端資訊。這比使用
oci_set_client_info() 較低效。
Roundtrip Gotcha
一些 OCI8 函式會導致 Roundtrips. 對數據庫來說當啟用結果快取時，查詢可能不產生 Roundtrips。
