LEARN ABOUT PHP

oci_set_module_name

OCI_SET_MODULE_NAME(3)													    OCI_SET_MODULE_NAME(3)

oci_set_module_name - Sets the module name

SYNOPSIS

       bool oci_set_module_name (resource  $connection, string	$module_name)

DESCRIPTION

	Sets the module name for Oracle tracing.

	The module name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement
       is executed.

	The 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.

PARAMETERS

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

	      o $module_name
		- User chosen string up to 48 bytes long.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

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.

EXAMPLES

       Example #1

	      Setting the module name

	      <?php

	      $c = oci_connect('hr', 'welcome', 'localhost/XE');

	      // Record the module
	      oci_set_module_name($c, 'Home Page');

	      // 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
	      // modules in use:

	      sqlplus system/welcome
	      SQL> select module from v$session;
