oci_set_action
(PHP 5.3.2, PECL OCI8 >= 1.4.0)
oci_set_action — Sets the action name
說明
$connection
, string $action_name
)Sets the action name for Oracle tracing.
The action name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed.
The action name can subsequently be queried from database administration views such as V$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
-
connection -
An Oracle connection identifier, returned by oci_connect(), oci_pconnect(), or oci_new_connect().
-
action_name -
User chosen string up to 32 bytes long.
回傳值
如果成功則回傳 TRUE，失敗則回傳 FALSE。
範例
Example #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 roundtrip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the actions // being performed: sqlplus system/welcome SQL> select action from v$session;
註釋
Note: Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10g onwards.
Performance
With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO package. This is less efficient than using oci_set_client_info().
Roundtrip Gotcha
Some but not all OCI8 functions cause roundtrips. Roundtrips to the database may not occur with queries when result caching is enabled.
