oci_set_client_info

oci_set_client_info

(PHP 5.3.2, PECL OCI8 >= 1.4.0)

oci_set_client_infoSets the client information

说明

bool oci_set_client_info ( resource $connection , string $client_info )

Sets the client information for Oracle tracing.

The client information is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed.

The client information can subsequently be queried from database administration views such as V$SESSION.

The value may be retained across persistent connections.

参数

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

User chosen string up to 64 bytes long.

返回值

成功时返回 TRUE, 或者在失败时返回 FALSE.

范例

Example #1 Setting the client information

<?php

$c 
oci_connect('hr''welcome''localhost/XE');

// Record the client information
oci_set_client_info($c'My Application Version 2');

// 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 client
// information:

sqlplus system/welcome
SQL> select client_info from v$session;

注释

Note: 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。

Tip

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。

Caution

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。
