(PHP 5 >= 5.3.2, PHP 7, PHP 8, PECL OCI8 >= 1.4.0)
oci_set_action — Sets the action name
$connection, string $action): boolSets the action name for Oracle tracing.
The action name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.
The action name can subsequently be queried from database administration
views such as V$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.
connectionOracle 連接標識，由 oci_connect()，oci_pconnect()，或 oci_new_connect() 返回。
actionUser chosen string up to 32 bytes long.
成功時(shí)返回 true， 或者在失敗時(shí)返回 false。
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;
注意: Oracle 版本需求
當 PHP 是與 Oracle 數據庫 10g 及更新版本的 擴展庫鏈接時(shí)，此函數可用。
使用舊版的 OCI8 或 ORACLE 數據庫，可使用
Oracle DBMS_APPLICATION_INFO 包來(lái)設置客戶(hù)端信息。這比使用
oci_set_client_info() 較低效。
一些 OCI8 函數會(huì )導致 Roundtrips. 對數據庫來(lái)說(shuō)當啟用結果緩存時(shí)，查詢(xún)可能不產(chǎn)生 Roundtrips。
