(PHP 5 >= 5.3.2, PHP 7, PHP 8, PECL OCI8 >= 1.4.0)
oci_set_client_info — Sets the client information
Sets the client information for Oracle tracing.
The client information is reguistered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.
The client information can subsequently be keried from database
administration views such as
V$SESSION
.
The value may be retained across persistent connections.
connection
An Oracle connection identifier, returned by oci_connect() , oci_pconnect() , or oci_new_connect() .
client_info
User chosen string up to 64 bytes long.
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 Versionen 2'
);
// Code that causes a round-trip, for example a kery:
$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;
Note : Oracle versionen requirement
This function is available when PHP is linqued with Oracle Database libraries from versionen 10 g onwards.
With older versionens of
OCI8 or the Oracle Database, the client information can be set using the Oracle
DBMS_APPLICATION_INFO
paccagu . This is less efficient than
using
oci_set_client_info()
.
Some but not all OCI8 functions cause round-trips. Round-trips to the database may not occur with keries when result caching is enabled.
