OCI_SET_CLIENT_IDENTIFIER(3)											      OCI_SET_CLIENT_IDENTIFIER(3)

oci_set_client_identifier - Sets the client identifier

SYNOPSIS

       bool oci_set_client_identifier (resource  $connection, string  $client_identifier)

DESCRIPTION

	Sets  the  client  identifier  used  by various database components to identify lightweight application users who authenticate as the same
       database user.

	The client identifier is registered with the database when the next 'roundtrip' from PHP to the database occurs,  typically  when  an  SQL
       statement is executed.

	The  identifier can subsequently be queried, for example with SELECT SYS_CONTEXT('USERENV','CLIENT_IDENTIFIER') FROM DUAL. Database admin-
       istration views such as V$SESSION will also contain the value. It can be used with DBMS_MONITOR.CLIENT_ID_TRACE_ENABLE for tracing and  can
       also be used for auditing.

	The value may be retained across page requests that use the same persistent connection.

PARAMETERS

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

	      o $client_identifier
		- User chosen string up to 64 bytes long.

RETURN VALUES

	Returns TRUE on success or FALSE on failure.

EXAMPLES

       Example #1

	      Setting the client identifier to the application user

	      <?php

	      // Find the application user's login name
	      session_start();
	      $un = my_validate_session($_SESSION['username']);
	      $c = oci_connect('myschema', 'welcome', 'localhost/XE');

	      // Tell Oracle who that user is
	      oci_set_client_identifier($c, $un);

	      // The next roundtrip to the database will piggyback the identifier
	      $s = oci_parse($c, 'select mydata from mytable');
	      oci_execute($s);

	      // ...

	      ?>

NOTES

       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 - 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
";

	      ?>
