oci_set_action

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

oci_set_actionSets the action name


说明

oci_set_action ( resource $connection , string $action_name ) : 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.


参数

connection
Oracle 连接标识,由 oci_connect()oci_pconnect(),或 oci_new_connect() 返回。
action_name
User chosen string up to 32 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 action

<?php$c = oci_connect('hr', 'welcome', 'localhost/XE');// Record the actionoci_set_action($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 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 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。
