There's an article "PHP Web Auditing, Authorization and Monitoring with Oracle Database" at www.oracle.com/technetwork/articles/dsl/php-web-auditing-171451.html which is all about using oci_set_client_identifier()
oci_set_client_identifier
(PHP 5 >= 5.3.2, PHP 7, PHP 8, PECL OCI8 >= 1.4.0)
oci_set_client_identifier — Sets the client identifier
Descrição
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 'round-trip' 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 administration 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.
Parâmetros
-
connection -
Um identificador de conexão Oracle, retornado por oci_connect(), oci_pconnect() ou oci_new_connect().
-
client_id -
User chosen string up to 64 bytes long.
Valor Retornado
Retorna true em caso de sucesso ou false em caso de falha.
Exemplos
Exemplo #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 round-trip to the database will piggyback the identifier
$s = oci_parse($c, 'select mydata from mytable');
oci_execute($s);
// ...
?>Notas
Cuidado
Pegadinha da Viagem de Ida e Volta
Algumas, mas não todas as funções do OCI8, causam viagens de ida e volta. Viagens de ida e volta ao banco de dados podem não ocorrer com consultas quando o cache de resultados estiver habilitado.
