<para>
|
|
<function>OCINLogon</function> creates a new connection to an
|
|
Oracle 8 database and logs on. The optional third parameter can
|
|
either contain the name of the local Oracle instance or the name
|
|
of the entry in tnsnames.ora to which you want to connect. If
|
|
the optional third parameter is not specified, PHP uses the
|
|
environment variables ORACLE_SID (Oracle instance) or TWO_TASK
|
|
(tnsnames.ora) to determine which database to connect to.
|
|
</para>
|
|
<para>
|
|
<function>OCINLogon</function> forces a new connection. This
|
|
should be used if you need to isolate a set of transactions. By
|
|
default, connections are shared at the page level if using
|
|
<function>OCILogon</function> or at the web server process level
|
|
if using <function>OCIPLogon</function>. If you have multiple
|
|
connections open using <function>OCINLogon</function>, all
|
|
commits and rollbacks apply to the specified connection only.
|
|
</para>

<para>
|
|
This example demonstrates how the connections are separated.
