Starting the Broker

On GT.M, to start the broker, you need to create an OS service (Xinetd on Linux) that calls GTMLNX^XWBTCPM.

On Cache, you can start a broker listener using the start-up file ZSTU by calling this: J ZISTCP^XWBTCPM1(<port no>):"<namespace>"

On Cache, you can also fill out the RPC Broker Site Parameters file like this:

Select OPTION NAME: XWB MENU       RPC Broker Management Menu


          RPC Listener Edit
          Start All RPC Broker Listeners
          Stop All RPC Broker Listeners
          Clear XWB Log Files
          Debug Parameter Edit
          View XWB Log

Select RPC Broker Management Menu <TEST ACCOUNT> Option: RPC LISTener Edit

Select RPC BROKER SITE PARAMETERS DOMAIN NAME: ?
    Answer with RPC BROKER SITE PARAMETERS DOMAIN NAME, or STATUS:

Select RPC BROKER SITE PARAMETERS DOMAIN NAME:    VISTA.PLATINUM 
Select BOX-VOLUME PAIR: ICARUS:icarus// 
  BOX-VOLUME PAIR: ICARUS:icarus// 
  Select PORT: 9000
  Are you adding '9000' as a new PORT (the 1ST for this LISTENER)? No// Y
  (Yes)
    STATUS: STOPPED// 
    TYPE OF LISTENER: ?
     Choose from: 
       0        Original
       1        New Style
    TYPE OF LISTENER: 1  New Style
    CONTROLLED BY LISTENER STARTER: ?
     Choose from: 
       0        NO
       1        YES
    CONTROLLED BY LISTENER STARTER: 1  YES

Then ask Taskman to start this upon Taskman start-up, by creating this entry in file 19.2:

OUTPUT FROM WHAT FILE: OPTION SCHEDULING// 
Select OPTION SCHEDULING NAME:    XWB LISTENER STARTER
ANOTHER ONE: 
STANDARD CAPTIONED OUTPUT? Yes//   (Yes)
Include COMPUTED fields:  (N/Y/R/B): NO//  - No record number (IEN), no Computed
 Fields

NAME: XWB LISTENER STARTER              SPECIAL QUEUEING: STARTUP

When you start taskman from ZSTU using J ^ZTMB:"<namespace>", the broker will be started by taskman.

Troubleshooting

Environment Check and Unit Test

The broker can fail at several points. All of them are covered by an environment check that either Wally or Joel wrote: D CHECK^XWBTCPMT. Here's an example:

GTM>D CHECK^XWBTCPMT

This will check for some of the errors that can prevent the Broker
from getting started.

Debugging is set to Very Verbose
Broker activity timeout is set to 180
Checking can Write to null device
The NULL device is OK.
Checking if new JOB's can start.
New jobs are allowed.
Done with the checks.

From the above, you can glean why a broker might not start or accept connections:

  1. The VOLUME multiple in the Kernel System Parameters isn't filled out properly.
  2. The VOLUME SET file has the disable flag set to yes.
  3. There is more than one NULL device or no NULL device.
  4. Your Mumps Implementation license doesn't allow you to start a new job.
  5. $$ACTJ^%ZOSV says you ran out of licenses.

In the same routine, there is also a broker tester to test your broker system by connecting to it, only you are doing it directly from Mumps. Here's an example:

GTM>D CALL^XWBTCPMT

Interactive Broker Test
IP ADDRESS: 127.0.0.1
PORT: 9200
Success, response: accept

If this call succeeds (and you need to make sure that this is indeed the right port that hooks up to your VISTA system), then you are now certain that the new style broker works to some extent.

Broker Logging

If you have further issues, the easiest way to troubleshoot them is to turn on broker logging.

The following illustrates the use of the RPCBroker logging functionality that was initially added by Wally Fort. This can be controlled from within the menu system or at the programmer level.

Caution -- If you use 'very Verbose' logging in a production system, it will create a very large amount of logging since it includes all input from the client as well as all output from the server. This may be overwhelming, since there is currently no mechanism provided to isolate logging to one or a few individuals. The use of very Verbose logging is best used in test systems or during off hours on a production system (and then remember to set it back down or off).

The following illustrates the different levels of logging and its control from within the menu system, starting at EVE or the System Manager Menu.

  
Select Systems Manager Menu Option: OPerations Management

Select Operations Management Option: RPC Broker Management Menu

          RPC Listener Edit
          Start All RPC Broker Listeners
          Stop All RPC Broker Listeners
          Clear XWB Log Files
          Debug Parameter Edit
          View XWB Log

Some essential parts to understand: a byte that is x04 (\04) always ends a message. A byte "f" means it's the end of the argument. The item just before the argument is the argument length (006). The client creates this message. Therefore, if this message is not created properly at the client, it won't be read properly by VISTA. VISTA replies usually start with x00x00 signifying that there is no error to send to the client.

Foreground Debugging of Broker Calls

Last but not least, for desperate debuggers, you can put breakpoints in your current process and run the listener process in the foreground and then connect your client. You will hit the breakpoint:

GTM>D DEBUG^XWBTCPM

Before running this entry point set your debugger to stop at
the place you want to debug. Some spots to use:
'SERV+1^XWBTCPM', 'MAIN+1^XWBTCPM' or 'CAPI+1^XWBPRS.'

or location of your choice.
