Connection time out from Database

Hi,

Hi we have application running on Unix Server(solaris10), which establishes connection(sessions) with DATABASE(oracle 10g) which is on another server and firewal is there in between. After some time i am usually getting connection time out(oarcle error 3114/3113) in some of my processes which were idle for sometime.

we have set idle time UNLIMITED in our database.Is there any rules in firewal??
Also i am using cluster Ip for both application and for database. I mean there is a clustering for Application as well as database.

thnks and regards

sqlsrv_connect

SQLSRV_CONNECT(3)														 SQLSRV_CONNECT(3)

sqlsrv_connect - Opens a connection to a Microsoft SQL Server database

SYNOPSIS

       resource sqlsrv_connect (string	$serverName, [array  $connectionInfo])

DESCRIPTION

	Opens  a  connection  to a Microsoft SQL Server database. By default, the connection is attempted using Windows Authentication. To connect
       using SQL Server Authentication, include "UID" and "PWD" in the connection options array.

PARAMETERS

	      o $serverName
		- The name of the server to which a connection is established. To connect to a specific instance, follow the server  name  with  a
		forward slash and the instance name (e.g. serverNamesqlexpress).

	      o $connectionInfo
		-  An associative array that specifies options for connecting to the server. If values for the UID and PWD keys are not specified,
		the connection will be attempted using Windows Authentication. For a complete  list  of  supported  keys,  see	SQLSRV	Connection
		Options.

RETURN VALUES

	A connection resource. If a connection cannot be successfully opened, FALSE is returned.

EXAMPLES

       Example #1

	      Connect using Windows Authentication.

	      <?php
	      $serverName = "serverNamesqlexpress"; //serverNameinstanceName

	      // Since UID and PWD are not specified in the $connectionInfo array,
	      // The connection will be attempted using Windows Authentication.
	      $connectionInfo = array( "Database"=>"dbName");
	      $conn = sqlsrv_connect( $serverName, $connectionInfo);

	      if( $conn ) {
		   echo "Connection established.<br />";
	      }else{
		   echo "Connection could not be established.<br />";
		   die( print_r( sqlsrv_errors(), true));
	      }
	      ?>

       Example #2

	      Connect by specifying a user name and password.

	      <?php
	      $serverName = "serverNamesqlexpress"; //serverNameinstanceName
	      $connectionInfo = array( "Database"=>"dbName", "UID"=>"userName", "PWD"=>"password");
	      $conn = sqlsrv_connect( $serverName, $connectionInfo);

	      if( $conn ) {
		   echo "Connection established.<br />";
	      }else{
		   echo "Connection could not be established.<br />";
		   die( print_r( sqlsrv_errors(), true));
	      }
	      ?>

       Example #3

	      Connect on a specifed port.

	      <?php
	      $serverName = "serverNamesqlexpress, 1542"; //serverNameinstanceName, portNumber (default is 1433)
	      $connectionInfo = array( "Database"=>"dbName", "UID"=>"userName", "PWD"=>"password");
	      $conn = sqlsrv_connect( $serverName, $connectionInfo);

	      if( $conn ) {
		   echo "Connection established.<br />";
	      }else{
		   echo "Connection could not be established.<br />";
		   die( print_r( sqlsrv_errors(), true));
	      }
	      ?>

NOTES

	By  default, the sqlsrv_connect(3) uses connection pooling to improve connection performance. To turn off connection pooling (i.e. force a
       new connection on each call), set the "ConnectionPooling" option in the $connectionOptions array to 0 (or FALSE). For more information, see
       SQLSRV Connection Pooling.

	The  SQLSRV  extension does not have a dedicated function for changing which database is connected to. The target database is specified in
       the $connectionOptions array that is passed to sqlsrv_connect. To change the database on an open connection, execute  the  following  query
       "USE dbName" (e.g. sqlsrv_query($conn, "USE dbName")).
