LEARN ABOUT PHP

oci_set_client_info

OCI_SET_CLIENT_INFO(3)													    OCI_SET_CLIENT_INFO(3)

oci_set_client_info - Sets the client information

SYNOPSIS

       bool oci_set_client_info (resource  $connection, string	$client_info)

DESCRIPTION

	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.

PARAMETERS

	      o $connection
		-An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3).

	      o $client_info
		- User chosen string up to 64 bytes long.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       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;

NOTES

       Note

	      Oracle version requirement

	      This function is available when PHP is linked with Oracle Database libraries from version 10 g onwards.

       Tip

	      Performance

	      With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle  DBMS_APPLICATION_INFO  pack-
	      age. This is less efficient than using oci_set_client_info(3).

       Caution

	      Roundtrip Gotcha

	      Some  but  not  all  OCI8  functions  cause roundtrips. Roundtrips to the database may not occur with queries when result caching is
	      enabled.
