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
";

	      ?>

oci_password_change - Changes password of Oracle's user

SYNOPSIS

       bool oci_password_change (resource  $connection, string	$username, string  $old_password, string  $new_password)

DESCRIPTION

       resource oci_password_change (string  $dbname, string  $username, string  $old_password, string	$new_password)

	Changes password for user with $username.

	The  oci_password_change(3)  function  is most useful for PHP command-line scripts, or when non-persistent connections are used throughout
       the PHP application.

PARAMETERS

	      o $connection
		- An Oracle connection identifier, returned by oci_connect(3) or oci_pconnect(3).

	      o $username
		- The Oracle user name.

	      o $old_password
		- The old password.

	      o $new_password
		- The new password to be set.

	      o $dbname
		- The database name.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      oci_password_change(3) example changing the password of an already connected user

	      <?php

	      $dbase	  = 'localhost/orcl';
	      $user	  = 'cj';
	      $current_pw = 'welcome';
	      $new_pw	  = 'geelong';

	      $c = oci_pconnect($user, $current_pw, $dbase);
	      oci_password_change($c, $user, $current_pw, $new_pw);
	      echo "New password is : " . $new_pw . "
";

	      ?>

       Example #2

	      oci_password_change(3) example of connecting and changing the password in one step

	      <?php

	      $dbase	  = 'localhost/orcl';
	      $user	  = 'cj';
	      $current_pw = 'welcome';
	      $new_pw	  = 'geelong';

	      $c = oci_pconnect($user, $current_pw, $dbase);
	      if (!$c) {
		  $m = oci_error();
		  if ($m['code'] == 28001) { // "ORA-28001: the password has expired"
		      // Login and reset password at the same time
		      $c = oci_password_change($dbase, $user, $current_pw, $new_pw);
		      if ($c) {
			  echo "New password is : " . $new_pw . "
";
		      }
		  }
	      }

	      if (!$c) {  // The original error wasn't 28001, or the password change failed
		  $m = oci_error();
		  trigger_error('Could not connect to database: '. $m['message'], E_USER_ERROR);
	      }

	      // Use the connection $c

	      ?>

NOTES

       Note

	       Changing the password either with this function or directly in Oracle should be done carefully. This is	because  PHP  applications
	      may  continue  to successfully reuse persistent connections by authenticating with the old password. The best practice is to restart
	      all web servers whenever the user password is changed.

       Note

	       If upgrading the Oracle client libraries or the database from a release prior to 11.2.0.3 to version 11.2.0.3 or higher,  oci_pass-
	      word_change(3)  may  give the error "ORA-1017: invalid username/password" unless both client and server versions are upgraded at the
	      same time.

       Note

	       The second oci_password_change(3) syntax is available since OCI8 version 1.1.

       Note

	       In PHP versions before 5.0.0 you must use ocipasswordchange(3) instead. This name still can be  used,  it  was  left  as  alias	of
	      oci_password_change(3) for downwards compatability. This, however, is deprecated and not recommended.
