oci_set_action

(PHP 5 >= 5.3.2, PHP 7, PHP 8, PECL OCI8 >= 1.4.0)

oci_set_action — Sets the action name

說(shuō)明

oci_set_action(resource $connection, string $action): bool

Sets the action name for Oracle tracing.

The action 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 action 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(shù)

connection

Oracle 連接標(biāo)識(shí)，由 oci_connect()，oci_pconnect()，或 oci_new_connect() 返回。

action

User chosen string up to 32 bytes long.

返回值

成功時(shí)返回 true， 或者在失敗時(shí)返回 false。

范例

示例 #1 Setting the action

<?php

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

// Record the action
oci_set_action($c, 'Friend Lookup');

// 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 actions
// being performed:

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

注釋

注意: Oracle 版本需求

當(dāng) PHP 是與 Oracle 數(shù)據(jù)庫(kù) 10g 及更新版本的 擴(kuò)展庫(kù)鏈接時(shí)，此函數(shù)可用。

小技巧

性能

使用舊版的 OCI8 或 ORACLE 數(shù)據(jù)庫(kù)，可使用 Oracle DBMS_APPLICATION_INFO 包來(lái)設(shè)置客戶端信息。這比使用 oci_set_client_info() 較低效。

警告

Roundtrip Gotcha

一些 OCI8 函數(shù)會(huì)導(dǎo)致 Roundtrips. 對(duì)數(shù)據(jù)庫(kù)來(lái)說(shuō)當(dāng)啟用結(jié)果緩存時(shí)，查詢可能不產(chǎn)生 Roundtrips。
