Hi all,
I suspect I'm having problems with socket functions within my PHP
application running on Red Hat 2.4.21-4.EL #1/PHP 4.3.2/Apache 2.0.46.
Below is a sample code listing:
================================================================
function sendRequest($strRequest) {
$parser = NULL;
$logman = new LogManager();
$resource = socket_create( AF_INET, SOCK_STREAM, SOL_TCP );
$logman->append("Connecting to OLS Server...");
$socket_conn = socket_connect( $resource, $serverIP, $serverPort );
if( $socket_conn ) {
$logman->append("Connected to {$serverIP}:{$serverPort}. Sending XML
request...");
socket_write( $resource, $strRequest );
$logman->append("XML request sent. Waiting for XML response...");
$document = "";
$data = socket_read( $resource, 1024 );
while ($data != "") {
$document .= $data;
$data = socket_read( $resource, 1024 );
}
$logman->append("XML response received.");
$parser = new OlsResponseParser;
// parse the received document using our parser
$parser->parse($document);
}
if ($parser != NULL) {
return $parser->getOlsResponse();
}
return $parser;
}
================================================================
The following listing is from the logs I have created...
================================================================

================================================================
As you can see, there is a lapse of more than one minutes between
LogId's 40 and 41, which is very slow on a production environment. The
script above acts as a client to another application server listening on
a remote port, running on Java. What the remote application reports is
that it receives the connection request, receives the request data, and
transmits the response data at the same second, while my application
receives the response one minute after the request was sent!
Other implementations in the enterprise using different architectures
and technologies/languages do not experience the same issue as my app does.
Please help. Comments, suggestions and thoughts through the group or
private mail are deeply appreciated.
Thanks!
