/PAE and TIME_WAIT (TNS-12542)

32bit, dando problema na quantidade de memória alocada no Oracle.
No boot.ini do servidor tem que conter o parâmetro /PAE, conforme mostra abaixo, para que o Windows reconheça mais de 3.xx gb de memória.

[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows Server 2003, Enterprise" /fastdetect /NoExecute=OptOut /PAE

Cause
Problem is caused due to the fact that the free ports in the windows client has been exhausted and it is trying to make use of a port which is in TIME_WAIT state which gives the error TNS-12542: Address already in use.

There are 2 solutions available:

1.) Increase the free port range:
======================
Start Registry Editor (Regedt32.exe).
Locate the following key in the registry:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters
On the Edit menu, click Add Value, and then add the following registry value:
Value Name: MaxUserPort Data Type: REG_DWORD Value: 65534
Valid Range: 5000-65534 (decimal) Default: 0x1388 (5000 decimal)
Description: This parameter controls the maximum port number used when an application requests any
available user port from the system. Normally, ephemeral (that is, short-lived) ports are allocated between the values of 1024 and 5000 inclusive.


2.) Decrease the value for TIME_WAIT state:
================================
TcpTimedWaitDelay (new in Windows NT versions 3.51 SP5 and later)
Key: Tcpip\Parameters
Value Type: REG_DWORD - Time in seconds
Valid Range: 30-300 (decimal)
Default: 0xF0 (240 decimal)
