Have you talked to the dba to see if the Oracle DB will accept more than one 
thread from the apache server?

Hi,

I am hoping that someone can help diagnose this issue.

I am able to successfully connect to and query a remote Oracle 9.2
database from apache2/php5. However, when I have multiple clients
hitting my php scripts, all of which require a connection to the
database, problems begin to occur. The first script running gets a
connection to the database, start performing queries, etc. While the
first connection is running all other pages hang while trying to
connect to the database until the first page finishes.

I have tried all of the following to no avail: oci_connect,
oci_new_connect, and oci_pconnect. The results are always the same,
only one connection opens, all others end up waiting.

I have found that I can connect to the DB through other methods at the
same time (jdbc, sqlplus).

Is it possible I have configured something incorrectly or I have the
wrong expectations? I could not find anything on the web concerning
this issue and I know there must be much higher traffic installations
that would have experienced this issue if it was widespread.

Any help would be greatly appreciated.

Using PHP5 and Apache 2 sounds daring.  What platform are you on?

If you can track down more information, file a bug at http://bugs.php.net/.
