Hello!
I'm not really sure what's going on here so hopefully this makes sense to someone. I have a CCDT file provided to me which specifies, in part:
| Code: |
"clientConnection": {
"queueManager": "QMGR",
"connection": [
{
"port": 1414,
"host": "[ip address]"
}
]
},
|
And I'm trying to connect with pymqi. I have the MQCHLLIB, MQCHLTAB, MQSSLKEYR, and MQCERTLABL environment variables set.
If I just run this (which has worked with a purely local server), I get an "MQRC_Q_MGR_NAME_ERROR" response:
| Code: |
qmgr = pymqi.QueueManager(None)
qmgr.connect_with_options("QMGR")
|
*However*, if I create a `pymqi.CD()` structure and then pass it in, with a *blank* name, it does connect:
| Code: |
cd = pymqi.CD()
cd.ChannelType = pymqi.CMQC.MQCHT_CLNTCONN
cd.TransportType = pymqi.CMQC.MQXPT_TCP
cd.ConnectionName = b"[ip address](1414)"
cd.SSLCipherSpec = b"ANY_TLS13_OR_HIGHER"
cd.ChannelName = b'the channel name'
qmgr.connect_with_options("", cd=cd)
|
That works fine. Trying just plain old `qmgr.connect_with_options("")` also doesn't work. So ? it seems as if the CCDT file is being somewhat ignored? That is, I have to pass in the data that the CCDT file contains, in the CD structure. Am I missing something obvious here? It seems as if this shouldn't be necessary when the CCDT file exists, and is being read, and from what I can tell this is the way to connect in a way that uses the CCDT data. |

Your CCDT JSON file doesn't look right. If you are trying to connect using SSL/TLS then where are those parameters?
Your CCDT JSON file should look more like:
| Code: |
{
"channel":
[
{
"name": "the_channel",
"clientConnection":
{
"connection":
[
{
"host": "localhost",
"port": 1414
}
],
"queueManager": "QM1"
},
"transmissionSecurity":
{
"cipherSpecification": "",
"certificateLabel": "",
"certificatePeerName": ""
},
"type": "clientConnection"
}
]
}
|
later
