Verifying TCP/IP parameter settings on Windows servers

Verify that the TCP/IP settings on all Windows servers in the FileNet® Image Services and Content Platform Engine systems are configured for optimal system performance.

About this task

The following TCP/IP settings affect the performance of content federation. Unless these parameters are set differently for other system reasons, adjust these parameter settings for optimal performance of the content federation system.
  • The MaxUserPort parameter determines the number of temporary ports that can be assigned on the server. These temporary ports are assigned by the server IP stack from a designated range of ports for this purpose. When network traffic is busy, it is possible to run out of temporary ports unless you increase the MaxUserPort setting.
  • The TcpTimedWaitDelay parameter determines the length of time the server waits before it reuses a closed ID socket. Although the default value is typically around 240 seconds (4 minutes), this parameter can safely be reduced to as little as 30 seconds on high-speed networks.
  • The TcpNumConnections parameter limits the maximum number of connections that TCP can have open simultaneously. If this parameter is not defined, the default value of 6,777,214 (0xFFFFFE) TCP connections is used.

Procedure

To verify the TCP/IP parameter settings:

  1. At the command prompt, enter the REGEDIT command to open the Windows registry editor.
  2. Click HKEY_Local_Machine > SYSTEM > CurrentControlSet > Services > Tcpip > Parameters .
  3. If the MaxUserPort parameter does not exist or is set to a value other than 65534 (decimal) or FFFE (hex), complete the following steps:
    1. If the parameter does not exist, create a new DWORD value with the name MaxUserPort.
    2. Set the value to 65534 (decimal) or FFFE (hex).
  4. If the TcpTimedWaitDelay parameter does not exist or is set to a value other than 30 seconds (decimal) or 1E (hex), complete the following steps:
    1. If the parameter does not exist, create a new DWORD value with the name TcpTimedWaitDelay .
    2. Set the value to 30 seconds (decimal) or 1E (hex).
  5. If the TcpNumConnections parameter exists, delete the parameter to set it to the default value.
  6. Close the Registry Editor window. Restart the server to put the new settings into effect.
