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.

OCI_ERROR(3)															      OCI_ERROR(3)

oci_error - Returns the last error found

SYNOPSIS

       array oci_error ([resource  $resource])

DESCRIPTION

	Returns the last error found.

	The function should be called immediately after an error occurs. Errors are cleared by a successful statement.

PARAMETERS

	      o $resource
		-  For	most  errors,  $resource  is  the resource handle that was passed to the failing function call. For connection errors with
		oci_connect(3), oci_new_connect(3) or oci_pconnect(3) do not pass $resource.

RETURN VALUES

	If no error is found, oci_error(3) returns FALSE. Otherwise, oci_error(3) returns the error information as an associative array.
