After taking over Network Administration in our organization, I developed the following instructions to assist new administrators in trouble-shooting SLPDA services.

Service Location Protocol Directory Agent Instructions

1. STOP SLPDA.

You must unload SLPDA from the "SLPDA Server". To do this, type "Unload SLPDA" at the server console screen and press enter.

2. START SLPDA.

  1. Start SLPDA Service

    From the System Console screen of the SLPDA server, type SLPDA (Figure 2) and press enter.


    Figure 2

  2. Force SLPDA Services

    From all other servers in the SLPDA setup, you will need to force the server's services to reconnect to the SLPDA service (Figure 3). At the server console,type the command "set slp reset=on" and press return.

3. CHECKING SLPDA SERVICES.

To check the health of the SLPDA service, complete the following steps.

  1. SLPDA Service Count

    From a System Console screen, type the Display SLPDA Services command as displayed (Figures 4) and press enter.


    Figure 4

    This will begin the display of the listed services (Figure 5). Continue pressing enter to cycle through the services until you get to the SLPDA Service count


    Figure 5

    After cycling through the services, the SLPDA Service count will be displayed (Figure 5). Compare this count to the count on all servers running SLPDA. If this count differs on any of the servers you will have to correct the problem.

  2. Display SLP DA

    Use the "Display SLPDA" command (Figure 6) to list all discovered DA in the network.

4. CLEAR SCOPEUNIT ITEMS

There may be a time when you need to clear the "Scope Unit" listings. To do this, first unload SLPDA. Then,

  • Open NW Admin or ConsoleOne and display the scope unit items (Figure 1).


Figure 1

  • Select and delete all the items listed.
  • Close NWAdmin or ConsoleOne.
  • Reload SLPDA.
  • Issue the following command on all servers: "set SLP reset=on".

Then use step 3 above to check the SLP services.

BE CAREFUL!!! DON'T DELETE OTHER OBJECTS!!!!!
