I have a QMgr created on an HP-UX machine.
I have a java application that tries to connect to the QMgr to get messages from the Q. Since the application is running on the same box, I am not specifying the hostname/port anywhere in the code.
I don't think that this also requires any configuration at the MQServer side.
Correct me if I am wrong.
When I try to run the code, it fails while trying to connect to the QMgr.
Fails with a reason code of 2059. i.e (QMGR NOT AVAILABLE)
But the QMgr is up and running. (verified with the dspmq command)
The id from which I am trying to run belongs to 'mqm' group. I have not given any explicit permissions on the QMgr and the other mq objects. Its just that I am part of mqm group as well as another group. So I think I have full access to my QMgr. Correct me if I am wrong.
I debugged the FDC and the ERR log created and here are the contents for the same -
/var/mqm/errors>vi AMQERR01.LOG

Surprisingly when I try to use the amsput and amqsget sample programs on the same QMgr and the Q, I am able to work fine with them.
This is what I am trying to do -
| Code: |
if(qMgr!=null && qMgr.isConnected()) qMgr.disconnect();
qMgr = new MQQueueManager(in_managername);
|
Also I am trying to run the program like -
| Code: |
nohup jreMQM -ms32m -mx128m -Djava.net.debug=all -Dorg.omg.CORBA.ORBClass=com.inprise.vbroker.orb.ORB -D
org.omg.CORBA.ORBSingletonClass=com.inprise.vbroker.orb.ORBSingleton -DConfigFile=${GITD_RootDir}/resource/MQConfig.cfg -Dexceptionconfig=${GITD_RootDir}/resource/MQConfig.cfg cititru.interdict.mq.MQMessageHandler >>&! ${GITD_Dir}/logs/MQ.log &
|
Where jreMQM --> java
and cititru.interdict.mq.MQMessageHandler --> My Program
Pls help me in resolving this.
Thanks in advance.

Looks to me like it is a permission error.
When connecting in bindings mode in java you are not allowed to use any user that may be different from the user you logged on to the machine. If you do you will not be authenticated and a permission error will be thrown.
Enjoy  |

I have logged on to the machine with the id which is a part of the mqm group. I have also created the QMgr and the other MQ objects like Q's and Channels with the same id.
| Code: |
/home/ftnoper>id
uid=44017(ftnoper) gid=205(support) groups=214(ftnapp),3040(mqm)
/home/ftnoper> dspmqaut -m SSPLATFLEXCU_QM.DV -t qmgr -p ftnoper
Entity ftnoper has the following authorizations for object SSPLATFLEXCU_QM.DV:
inq
set
connect
altusr
crt
dlt
chg
dsp
setid
setall
|
If it allows me to create/start/stop/dlt/ that QMgr with this id..still is there a chance of being a permission issue..? |

Roger,
I think the permissions that you are mentioning are for Q's and not a QMgr.
In any case is it possible that not having a permission for put/get on a Q throws you with 2059..??
I will anyway check the permissions on the Q and let you know.

Mitul |

Your permission problem may not necessarily be an mq permission problem. What is shmat ? This is part of the authentication process ?
is the user declared to the OS and in the right group ?

I have no clue about shmat.
Its just that when i dug the FDC is found this.
Also I assume that the user is declared to the OS and in the rt group.
Otherwise I won't be able to login with that id and create the QMgrs..!!
Correct me if I am wrong.

shmat - shared memory attach operation
I'm not fit with HP-UX, but it looks like an problem attaching shared memory.
On unix, mqm uses the setuid-bit to set the effective uid and gid, maybe one of your file-permission isn't set right or there is a mq-component(listener, commandserver, ... ) started by a wrong user( root ? ).

Have you tried the Java IVP?
I hadn't done bindings mode in a long time and the script that I have set up uses a client channel. To use bindings I ended up having to add a export SHLIB_PATH=/opt/mqm/java/lib
but try running the ivp in: /opt/mqm/samp/java/base/MQIVP.class
I ran mine today without being in the mqm group.
Good Luck

Thanks Leo,
I will forward this link to my administrator
I have also confirmed that the error occurs only for Bindings mode.
Probably either the shared memory error.
Also our admin is researching the ownerships of some of the directories. Looks like some are with 'root'
Thanks everybody. I will get back to you if required or hopefully once this issue is resolved.

Yes, the shmat alerts are related to your shared memory resources.
