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

说明

oci_set_module_name(resource $connection, string $name): bool

Sets 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.

参数

connection

Oracle 连接标识，由 oci_connect()，oci_pconnect()，或 oci_new_connect() 返回。

name

User chosen string up to 48 bytes long.

返回值

成功时返回 true， 或者在失败时返回 false。

示例

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;

注释

注意: Oracle 版本需求

当 PHP 是与 Oracle 数据库 10g 及更新版本的 扩展库链接时，此函数可用。

小技巧

性能

使用旧版的 OCI8 或 ORACLE 数据库，可使用 Oracle DBMS_APPLICATION_INFO 包来设置客户端信息。这比使用 oci_set_client_info() 较低效。

警告

Roundtrip Gotcha

一些 OCI8 函数会导致 Roundtrips. 对数据库来说当启用结果缓存时，查询可能不产生 Roundtrips。
