oci_set_action
(PHP 5 >= 5.3.2, PHP 7, PHP 8, PECL OCI8 >= 1.4.0)
oci_set_action — Sets the action name
Description
$connection, string $action): boolSets the action name for Oracle tracing.
The action name is registered with the database when the next 'round-trip' from PHP to the database occurs, typically when an SQL statement is executed.
The action name can subsequently be queried from database administration
views such as V$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 -
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 round-trip, for example a query:
$s = oci_parse($c, 'select * from dual');
oci_execute($s);
oci_fetch_all($s, $res);
sleep(30);
?>
// While the script is running, the administrator can see the actions // being performed: sqlplus system/welcome SQL> select action from v$session;
Notes
Note: Oracle version requirement
This function is available when PHP is linked with Oracle Database libraries from version 10g onwards.
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().
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.
