oci_set_client_info
(PHP 5.3.2, PHP 7, PECL OCI8 >= 1.4.0)
oci_set_client_info — Sets the client information
설명
$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.

예제
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;
주의
Note: 오라클 버전 요구사항
이 함수는 PHP가 오라클 데이터베이스 라이브러리 버전 10g 이상과 연결되었을 때만 사용할 수 있습니다.
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.
