oci_set_client_identifier
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.
Parameters
- connection
-
An Oracle connection identifier, returned by oci_connect, oci_pconnect, or oci_new_connect.
- client_id
-
User chosen string up to 64 bytes long.
Return Values
Returns true on success or false on failure.
Notes
Caution:
Round-trip GotchaSome but not all OCI8 functions cause round-trips. Round-trips to the database may not occur with queries when result caching is enabled.
