DataGate/400 Service won’t start 

SYMPTOMS

Any of these symptoms may exist:

  • DataGate/400 Server won't start after entering the DG8_40/STRDG8SVR command and no errors are generated.  Sometimes you will see the error "error binding socket, 3420" in the Job Log or Spool File.
  • An upgrade to OS/400 V4R4 or higher (V4R5) has occurred
  • An IPL has occurred.

RESOLUTION

Here are some possible changes that may cause the DataGate/400 not running:

  • The TCP/IP Port (5042) assigned to DataGate is in use by IBM’s WSG (Workstation Gateway).  This problem usually occurs after upgrading to OS/400 V4R4 and higher.
  • Security or Configuration has changed on the AS/400.
  • Objects that DataGate needs to run are no longer there.
  • TCP/IP or QINTER Subsystem is not running.

MORE INFORMATION

To find more information on how to determine what AS/400 User Profile is using the Acceler8DB Port (5042) by following these steps:

  1. At Command line, type: WRKTCPSTS or NETSTAT
  2. Select Option 3
  3. Press F14 to see the numeric values on the local ports column
  4. Press F11 to see the User connected to the Port.
  5. Under the local ports column find and entry that reads 5042.

If you find that the port is being used by a different service (i.e. IBM's Workstation Gateway) other than DataGate/400 (Acceler8DB), then you will have to decide which service keeps the port and assign a different port number to the other service.  If the port in conflict is indeed 5042, then you should probably assign it to DataGate/400 since it has been official registered by ASNA with the Internet Assigned Numbers Authority, for a list of all assigned ports click here. To change a port number use the command WRKSRVTBLE.

NOTE: This is port status information example shows that the user profile associated with the port 5042 is QTMTWSG when it should be DG8SVCPRF- the DataGate/400 user profile.
