Description

bool oci_set_action ( resource $connection , string $action_name )

Sets the action name for Oracle tracing.

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

The action 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().
action_name: User chosen string up to 32 bytes long.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

Example #1 Setting the action


<?php

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

// Record the action
oci_set_action($c, 'Friend Lookup');

// 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 actions
// being performed:

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

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

Roundtrip Gotcha

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