Hi,
I am using Mq series 5.3 and doing a .NET Client connection to read messages from a Q. We have three MQ Series server running on Z/OS. I am able to do it succesfully for two of them. For the third I face the following problem.
With this code:
| Code: |
try
{
mqQMgr = new MQQueueManager(QMgr);
mqQueue = mqQMgr.AccessQueue(QName, MQC.MQOO_FAIL_IF_QUIESCING | MQC.MQOO_INPUT_SHARED | MQC.MQOO_INQUIRE);
MQMessage mqMsg; // MQMessage instance
MQGetMessageOptions mqGetMsgOpts; // MQGetMessageOptions instance
string msg;
while (true)
{
msg = "";
mqMsg = new MQMessage();
mqGetMsgOpts = new MQGetMessageOptions();
mqGetMsgOpts.WaitInterval = 10;
mqGetMsgOpts.Options = MQC.MQGMO_SYNCPOINT;
mqQueue.Get(mqMsg, mqGetMsgOpts );
msg = mqMsg.ReadString(mqMsg.MessageLength);
}
if (LogMessageToSQL(guid, msg, QMgr, 0, 1))
{
mqQMgr.Commit();
}
else
{
mqQMgr.Backout();
throw new System.ApplicationException("LogMessageToSQlDBFailed");
}
}
catch (MQException mqe)
{
if ( mqe.Reason == MQC.MQRC_NO_MSG_AVAILABLE )
{
Thread.Sleep(sTime);
}
else
{
Thread.CurrentThread.Abort();
}
}
catch (Exception e)
{
Thread.CurrentThread.Abort();
}

This gives me a 2035 Error. User access problem.. I checked the MQ logs and .NET was trying to connect using a USER(SYSTEM) id.
So I changed my user id by using the following code:
| Code: |
try
{
mqQMgr = new MQQueueManager(QMgr);
mqQueue = mqQMgr.AccessQueue(QName, MQC.MQOO_FAIL_IF_QUIESCING | MQC.MQOO_INPUT_SHARED | MQC.MQOO_SET_IDENTITY_CONTEXT);
MQMessage mqMsg; // MQMessage instance
MQGetMessageOptions mqGetMsgOpts; // MQGetMessageOptions instance
string msg;
while (true)
{
msg = "";
mqMsg = new MQMessage();
mqMsg.UserId = "NEWID"; // Fictitious ID :)
mqGetMsgOpts = new MQGetMessageOptions();
mqGetMsgOpts.WaitInterval = 10;
mqGetMsgOpts.Options = MQC.MQGMO_SYNCPOINT;
mqQueue.Get(mqMsg, mqGetMsgOpts );
msg = mqMsg.ReadString(mqMsg.MessageLength);
}
if (LogMessageToSQL(guid, msg, QMgr, 0, 1))
{
mqQMgr.Commit();
}
else
{
mqQMgr.Backout();
throw new System.ApplicationException("LogMessageToSQlDBFailed");
}
}
catch (MQException mqe)
{
if ( mqe.Reason == MQC.MQRC_NO_MSG_AVAILABLE )
{
Thread.Sleep(sTime);
}
else
{
Thread.CurrentThread.Abort();
}
}
catch (Exception e)
{
Thread.CurrentThread.Abort();
}

This gave me a 2046 Error. MQRC_OPTIONS_ERROR. I dont see anything on my MQLog for this. Does this mean that:
1. I failed because of the Options Error before I even tried to access the mainframe
2. Or that I was able to access the Q but because of invalid options I was not able to Read.
Can somebody pls help me on how to set the ID with the correct options so that I can read the messages correctly.
Thanks

The user ID that's being validated isn't set on the MQMessage.
It's set on the connection.
So by the time you get to the statement that either is wrong (and gives you a 2046) or tries to do something the user isn't authorized to (and gives you a 2035), it's too late to change the user.
Look at the documentation of the constructors for MQQueueManager, or look for .NET versions of the MQCONNX call.

| Look under the 'documentation' at the top of this page. You want the 'Library Home Page'. |

Hi,
I tried several scenarios But am failing to do a .NET Client connect to a MQ Serier Server Running on z/OS. When I am logged in as Administrator, it connects as:
| Quote: |
TC08562 IRR012I VERIFICATION FAILED. USER PROFILE NOT FOUND
TC08562 ICH408I USER(ADMINIST) GROUP( ) NAME |
I want to overide that USER(ADMINIST) with a user id I set in code. Is it possible ?
Here is a snippet of the code i tried:
| Code: |
MQEnvironment.Hostname = QMgr;
MQEnvironment.Channel = "TO." + QMgr + ".SOP.00";
MQEnvironment.Port = Qport;
MQQueueManager mqQMgr = null;
MQQueue mqQueue = null;
try
{
mqQMgr = new MQQueueManager(QMgr);
mqQMgr.AlternateUserId = "bc8ktw3";
Console.WriteLine("Connected to Qmgr:"+mqQMgr.Name.Trim());
// Works good till here
mqQueue = mqQMgr.AccessQueue(QName, MQC.MQOO_FAIL_IF_QUIESCING | MQC.MQOO_INPUT_SHARED | MQC.MQOO_ALTERNATE_USER_AUTHORITY,QMgr,null,"bc8ktw3");
// but not if MQM stopping
// THROWS a 2035 Exception here.
Console.WriteLine("Connected to Qname:"+mqQueue.Name.Trim());
}
catch (MQException mqe)
{
Console.WriteLine("QMgr/QName exception:"+mqe.Message);
Thread.CurrentThread.Abort();
}
|
Any help is appreciated. I have to do a proof of concept Tomm/Monday latest.
Thanks
