oci_set_module_name — Sets the module name
$module_name) : bool
Sets the module name for Oracle tracing.
The module name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.
The name can subsequently be queried from database administration views such as V$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.
TRUE on success or
FALSE on failure.
Note: Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10g onwards.
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().
Some but not all OCI8 functions cause round-trips. Round-trips to the database may not occur with queries when result caching is enabled.
Example #1 Setting the module name
$c = oci_connect('hr', 'welcome', 'localhost/XE');
// Record the module
oci_set_module_name($c, 'Home Page');
// Code that causes a round-trip, for example a query:
$s = oci_parse($c, 'select * from dual');
// While the script is running, the administrator can see the // modules in use: sqlplus system/welcome SQL> select module from v$session;
