Hi All,
I don't know if it is the correct discussion forum to post about new Messaging using the REST API in IBM MQ
we are using IBM MQ Version: 9.0.4.0 with multi-instance queue managers.
we are trying the new REST API feature provided with IBM MQ.
we are using the strmqweb command to start the web server and we are provided with URL's like this
| Code: |
https://localhost:9443/ibmmq/rest/v1/
https://localhost:9443/ibmmq/console/ |
we are using the https://localhost:9443/ibmmq/rest/v1/messaging/qmgr/QM1/queue/Q1/message with http post method to put messages into Queue and we are able to put messages into Queue without any issues
and the same way we are calling the HTTP DELETE method to get the messages from the queue.
all this setup works fine when we have only one queue manager but we have queue managers configured with Multi-instance when QM in server A goes down then QM in server B will become an active instance of the queue manager.
I'm little puzzled here about the rest API, I am able to see the web folder in both primary and standby server.
how do I work with the messaging REST API with Multi-instance queue manager?
any limitation, possible factors to consider anything please throw some lights |

| just found how to covert the mqweb as window service, but still unable to find out how to use it for the multi-instance broker. |

How did you cover running mqweb as a windows service ?
I think it might be challenging using multi-instance Queuemanagers in an active/passive setting since you cannot run two queue managers with the same name.
You would have to define the same queues on both queue managers, and do a retry on secondary queue manager if the first one running has gone *down*.
Certainly doable but not too pretty of a solution really.
I'd make sure that the first queue manager would have as much availablity as possible.
Have you checked why the first one goes down, or do you plan to take it down for servicing only and offload messaging to the secondary one ?
You can only have one primary queuemanager per server as far as i know, so multi-tenancy comes with it's challenges.

i have used WLP commands to start the mqweb.bat file as a windows service the link to that is
https://www.ibm.com/support/knowledgecenter/en/SSEQTP_liberty/com.ibm.websphere.wlp.doc/ae/twlp_setup_new_server_winserv.html
Use the following command to start the server:
server startWinService serverName [options]
in our case the command would be Use the following command to start the server:
| Code: |
server registerWinService mqweb
server startWinService mqweb
|
note that we need to run this command in admin mode and location to run this command is mqinstallationdir/ibm/mq/web/bin
you will get some errors related to log '' folder issue then open the server.bat and check this statement
| Code: |
!WLP_INSTALL_DIR!\bin\tools\win\prunsrv.exe //IS//%SERVER_NAME% --Startup=manual --DisplayName="%SERVER_NAME%" --Description="IBM WebSphere Liberty Profile" ++DependsOn=Tcpip --LogPath="%WLP_INSTALL_DIR%\usr\servers\%SERVER_NAME%\logs" --StdOutput=auto --StdError=auto --StartMode=exe --StartPath="%WLP_INSTALL_DIR%" --StartImage="%WLP_INSTALL_DIR%\bin\server.bat" ++StartParams=start#%SERVER_NAME% --StopMode=exe --StopPath="%WLP_INSTALL_DIR%" --StopImage="%WLP_INSTALL_DIR%\bin\server.bat" ++StopParams=stop#%SERVER_NAME% |
create log manually and run the commands as mentioned using above URL you can find service named mqweb in your windows services .
| Code: |
| just found how to covert the mqweb as window service, but still unable to find out how to use it for the multi-instance broker. |
i'm sorry on the above statement i was supposed to type multi instance queue managers here not broker .
i presume you already know about multi instance queue mangers but just in case for others URL to mult instance queue manger concept
https://www.ibm.com/support/knowledgecenter/en/SSFKSJ_9.0.0/com.ibm.mq.con.doc/q018140_.htm
is your question related to Multi instance queue mangers? concept if yes we use configuration as mentioned in the infocenter. |

Thanks for the help configuring mqweb as a window service.
Still having issues though, since it behaves differently depending on if i start mqweb from "services" or if i just key "strmqweb" from command line.
The "strmqweb" works fine, but running it as a windows service does not work.
Trying to pinpoint why, without success.
Log states :
[ERROR ] CWWKE0701E: [com.ibm.ws.security.registry.internal.UserRegistryServiceImpl(53)] The setUserRegistry method has thrown an exception Bundle:com.ibm.ws.security.registry(id=81) java.lang.UnsatisfiedLinkError: com/ibm/mq/rest/auth/osauth/v1/MQLocalAuthenticationV1.getRealmMethod()Ljava/lang/String;
at com.ibm.mq.rest.auth.osauth.v1.MQLocalAuthenticationV1.getRealm(MQLocalAuthenticationV1.java:400)
at [internal classes]
We are not running this in production yet, hopefully will be able to do so in the near future. Only Sandbox/Development at the moment.

Actually ended up setting the 'strmqweb' as a scheduled task, run at startup.
Not sure why the Liberty server did not work, could not find any useful pointers either to have it run as i wanted.

Hi Boloro,
It was working for me both windows service and strmqweb as batch script program for basic registry while using below
| Code: |
<featureManager>
<feature>appSecurity-2.0</feature>
<feature>basicAuthenticationMQ-1.0</feature>
</featureManager>
|
But i too faced the same issue in doing window service when using, local os authentication registry file that has below features.
| Code: |
<featureManager>
<feature>appSecurity-2.0</feature>
<feature>localOSAuthenticationMQ-1.0</feature>
<feature>basicAuthenticationMQ-1.0</feature>
</featureManager>
|
i have debugged the error is with environment variables if you can check your log files in the location web\installations\yourinstalltion\servers\mqweb\logs\messages
while running as strmqweb :
| Code: |

but the error is throwing for local os service registry as below running as windows service
| Code: |

|
if you can compare both the errors the reason is while using local os authentication features the service is not finding Native security library C:\Program Files\IBM\MQ\bin64\amqzfuf1.dll could not be loaded.
that is due to ibm mq product was not installed in the default location .
hope it helps understaing error |

Thanks for the tip!
That most likely is the issue.
Found this :http://nssm.cc/
Seems it works pretty nice setting up windows services out of pretty much anything.
Will try and see how it goes.
