oci_set_module_name - Sets the module name
Code Examples

oci_set_module_name( resource$connection, string$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.



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


User chosen string up to 48 bytes long.

Return Values

Returns true on success or false on failure.


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.

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.
