How do you know if a site has implemented the NLM.

Is the LH…TSR.EXE having to be run, the indicator, or is that just a Novell thing.

Barry,

Try running NLM_STATS (usually in Sysobj)

If the NLM is running you'll get lots of pretty statistics

The LHIPXTSR is a "keep alive" message to let the NLM know that the station is there. Your question can be answered in many ways - an easy way to check that the NLM is working is to open the VOC file and check for FFFFFF in the file handle but you probably know this.

What exactly do you want to check for?

I have a new client (Old Arev user, new for me) and I noticed they did not have the NPP installed. In the NPP docs it says not required if NLM loaded.

re FFFFFF, no, I did not know that.

Thanks!

What other thing can you do in Arev that are NLM specific.

Barry

Barry ..

The NLM does not use the NPP driver. It uses the IPX - NLM driver. A non-programatic way to test to see if the driver is loaded is to type WHO at the TCL and check the driver. Programatically, the way to do it is to open the VOC for the account and to check the file handle for the FFFFFFF string:

OPEN VOC TO HANDLE then

.. check the handle by looking in variable HANDLE. This will tell you whether the TSR is loaded and communicating with the NLM driver. If the HANDLE doesn't end in the FFFFFFF string then the workstation's VOC (and therefor the app) is not under control of the NLM.

Quick way to do this is from TCL Type

:EVAL OPEN "VOC" TO HANDLE THEN PRINT HANDLE

Here's a snippet of code that I have used frequently in AREV:

CALL GETCONFIGURE(ERROR)

* CHECK THE LAN DRIVER

LAN.DRV=ERROR

IF LAN.DRV1,3=IPX' THEN

  DECLARE FUNCTION IsTSR

• ROUTINE TO CHECK TO SEE IF THE NOVELL NETWARE NLM IS LOADED

• DON'T DO I/O IF NOT

  IF IsTSR() THEN    /* IF TSR IS LOADED, NO ACTION IS REQUIRED */

      NULL

  END ELSE

      RESP='

      MSG.TXT=You don't have LHIPXTSR loaded!  Logging off!!!"

      ECHO OFF

      MSG(MSG.TXT,'RI',RESP,'')

      ECHO ON

• THE CODE BELOW ALLOWS FOR EMERGENCY ACCESS IN THE EVENT OF CATASTROPHIC

• FAILURE

      IF RESP NE 'PRIV' THEN EXECUTE "OFF"

  END

• CHECK TO SEE IF NULL @STATION - THIS WILL CAUSE BIG PROBLEMS

  IF @STATION=' THEN

      MSG.TXT=Unable to obtain Workstation ID!  Logging off!!!"

      RESP='

      ECHO OFF

      MSG(MSG.TXT,'RI',RESP,'')

      IF RESP NE 'PRIV' THEN EXECUTE "OFF"

  END

• CHECK TO SEE IF THE VOC FILE IS UNDER CONTROL OF THE NLM

• THE FILE HANDLE WITH BE "FFFFFF" IF SO OTHERWISE IT WILL BE A DOS

• FILE HANDLE

  OPEN "VOC" TO VOC THEN

      IF INDEX(VOC,"FFFFFF",1) ELSE

           MSG.TXT=The VOC file is NOT under the NLM'S Control!|"

           MSG.TXT:=|Please contact the system administrator     '

           MSG.TXT:=|You will now be logged off!!                '

           RESP='

           ECHO OFF

           MSG(MSG.TXT,'RI',RESP,'')

           ECHO ON

• THE CODE BELOW ALLOWS FOR EMERGENCY ACCESS IN THE EVENT OF CATASTROPHIC

• FAILURE

           IF RESP NE 'PRIV' THEN EXECUTE "OFF"

      END

  END

END

Hope this is useful..
