(PHP 5.3.2, PECL OCI8 >= 1.4.0)
oci_set_module_name — Sets the module name
說明
bool oci_set_module_name ( resource$connection
, string $module_name
)
Sets the module name for Oracle tracing.
The module name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed.
The name can subsequently be queried from database administration views such as V$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 連接標識,由 oci_connect(),oci_pconnect(),或 oci_new_connect() 返回。
module_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
。
注釋
Note: Oracle 版本需求
當 PHP 是與 Oracle 數據庫 10g 及更新版本的 擴展庫鏈接時,此函數可用。
Tip性能使用舊版的 OCI8 或 ORACLE 數據庫 ,可使用 Oracle DBMS_APPLICATION_INFO 包來設置客戶端信息。這比使用 oci_set_client_info() 較低效。
CautionRoundtrip Gotcha一些 OCI8 函數會導致 Roundtrips. 對數據庫來說當啟用結果緩存時,查詢可能不產生Roundtrips。
范例
Example #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 roundtrip, 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;
