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_SET_EDITION(3)														OCI_SET_EDITION(3)

oci_set_edition - Sets the database edition

SYNOPSIS

       bool oci_set_edition (string  $edition)

DESCRIPTION

	Sets the database "edition" of objects to be used by a subsequent connections.

	Oracle Editions allow concurrent versions of applications to run using the same schema and object names. This is useful for upgrading live
       systems.

	Call oci_set_edition(3) before calling oci_connect(3), oci_pconnect(3) or oci_new_connect(3).

	If an edition is set that is not valid in the database, connection will fail even if oci_set_edition(3) returns success.

	When using persistent connections, if a connection with the requested edition setting already exists, it is reused. Otherwise, a different
       persistent connection is created

PARAMETERS

	      o $edition
		- Oracle Database edition name previously created with the SQL " CREATE EDITION" command.

NOTES

       Note

	      Oracle version requirement

	       This function is available from Oracle 11 gR2 onwards.

       Caution

	      Persistent connections

	       To  avoid  inconsistencies  and unexpected errors, do not use ALTER SESSION SET EDITION to change the edition on persistent connec-
	      tions.

       Caution

	      DRCP Connection Pooling

	       To avoid inconsistencies and unexpected errors when using editions and DRCP with Oracle 11.2.0.1, keep a one-to-one  correspondence
	      between  the  oci8.connection_class and the edition name used by applications. Each pooled server of a given connection class should
	      only be used with one edition. This restriction has been removed with Oracle 11.2.0.2.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Two scripts can use different versions of myfunc() at the same time

	      <?php

	      // File 1

	      echo "Version 1 of application
";

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

	      $s = oci_parse($c, "begin :r := myfunc(); end;");
	      oci_bind_by_name($s, ":r", $r, 20);
	      oci_execute($s);
	      echo "The result is $r
";

	      ?>

	      <?php

	      // File 2

	      echo "Version 2 of application
";

	      oci_set_edition('E1');
	      $c = oci_connect('hr', 'welcome', 'localhost/XE');

	      $s = oci_parse($c, "begin :r := myfunc(); end;");
	      oci_bind_by_name($s, ":r", $r, 20);
	      oci_execute($s);
	      echo "The result is $r
";

	      ?>
