<para>
Sets the DBOP for Oracle tracing.

<para>
The database operation name is registered with the database when the next
'round-trip' from PHP to the database occurs, typically when a SQL
statement is executed.
</para>
<para>
The database operation can subsequently be queried from database administration
views such as <literal>V$SQL_MONITOR</literal>.
</para>
<para>
The <function>oci_set_db_operation</function> function is available
when OCI8 uses Oracle 12 (or later) Client libraries and Oracle Database 12 (or later).
