OCI_SET_ACTION(3)														 OCI_SET_ACTION(3)

oci_set_action - Sets the action name

SYNOPSIS
bool oci_set_action (resource $connection, string $action_name) DESCRIPTION
Sets the action name for Oracle tracing. The action name is registered with the database when the next 'roundtrip' from PHP to the database occurs, typically when an SQL statement is executed. The action name can subsequently be queried from database administration views such as V$SESSION. It can be used for tracing and monitor- ing such as with V$SQLAREA and DBMS_MONITOR.SERV_MOD_ACT_STAT_ENABLE. The value may be retained across persistent connections. PARAMETERS
o $connection -An Oracle connection identifier, returned by oci_connect(3), oci_pconnect(3), or oci_new_connect(3). o $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 10 g onwards. Tip Performance With older versions of OCI8 or the Oracle Database, the client information can be set using the Oracle DBMS_APPLICATION_INFO pack- age. This is less efficient than using oci_set_client_info(3). 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. SEE ALSO
oci_set_module_name(3), oci_set_client_info(3), oci_set_client_identifier(3). PHP Documentation Group OCI_SET_ACTION(3)
