# oci_set_module_name

(PHP 5 >= 5.3.2, PHP 7, PECL OCI8 >= 1.4.0)

oci_set_module_name — Sets the module name

### Description

oci_set_module_name ( resource `$connection` , string `$module_name` ) : bool

Sets the module name for Oracle tracing.

The module 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 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

`connection`

  An Oracle connection identifier, returned by oci_connect(), oci_pconnect(), or oci_new_connect().

`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 10g onwards.

Tip

# 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().

Caution

# Round-trip Gotcha

Some but not all OCI8 functions cause round-trips. Round-trips 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 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
    // modules in use:

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