    I am investigating setting up queue managers using the MQ 9.2 Operator on cloud environments. According to the manual, only LDAP based authentication is supported because of issues with privilege escalation which are not allowed in OpenShift. Fair Enough.

    However, what if I don't want to authenticate the users with a password (which would need the escalation) and just want to attach some OAM rules to an account for an MCAUSER, and I'll authenticate with mutual TLS.

    I've built a version of the MQ container image (as a PoC) with a bunch of local groups and users. The accounts are locked, have an invalid shell (/bin/false) and basically can't do anything. They have no rights within the OS image. I create them in the container build phase with AS ROOT, RUN and then groupadd and useradd. I don't care what id numbers they have because MQ doesn't care either.

    I can run the container via the operator and create channels which use TLS. The channels assert these userids, and I have granted permissions against them. Things work as they would on any other normal queue manager.

    The use case is for a queue manager which doesn't require password based authentication for client channels, and is using TLS authentication. Password based authentication of local connections doesn't really make sense in a container environment, so I'm not worried about that either. Setting up an LDAP just for hanging MQ permissions on isn't something I really want to do.

    Can I ask why this configuration is not supported?

    I may not be on the call (for timezone reasons) but I'll catch up with it after the fact if it is available for replay.

    Hi Neil,

    As you've seen, to be compatible with OpenShift's restricted SCC we're not supporting local OS users within the supported MQ container image. However, you're spot on with your reasoning for having a "user" simply to hang authority records from but unfortunately MQ currently requires either an OS user or one from LDAP.

    You'll actually find that the latest MQ developer image (https://github.com/ibm-messaging/mq-container - since 9.1.5 I think) has been tweaked to provide a couple of simple users that are neither in the OS or LDAP. Providing that type of capability in the fully supported product is something we're investigating.

    David.

    Thanks David,

    would not adjusting the support statement such that "CONNAUTH using IDPWOS is only supported/permitted when CHCKCLNT and CHCKLOCL are both set to NONE" solve the issue, without needing to modify MQ to support a local user store?

    Regards,

    Neil

    Hi Neil,
    That's a possible route forward to avoid stepping outside the limits of restricted SCC, we'll have a think about that. I think moving to a world where no local OS users are actually required would be an even better solution, but obviously that would be something for the future.

    Are you aware of problems with RDQM on LTS versions ? I've been running into several problems trying to run RDQM queue managers using RHEL 7.6 and 8.2 with MQ 9.1.XX LTS versions as well as 9.2.0.0. I could not create a PMR yet as we are not ready with the systems on my employers site. The tests I've done so far are on my test lab with MQ Developer versions. I did not have any problems with CD versions like 9.1.4.0 and 9.1.5.0. I've posted a thread on the subject on the mqseries.net site: http://www.mqseries.net/phpBB2/viewtopic.php?t=77417

    Hi Gerhard,

    I also had problems with installing RQDM, but with the help of @Morag Hughson  I have solved it. What I did was stick to the basics and don't install pacemaker yourself. IBM has a script for that.
    I can send you my install manuals if you want.​ They are in Dutch but I don't hink its a problem. I managed to ge the system working even on AWS on a couple of EC2 instances.
    Kind regards

    Hello Bernard,
    I would love to read your install manual. It might help (I do understand some basic Dutch :) ). For what it's worth, I've tried many different approaches already, with the installRDQMsupport script and also manually. It might also be worth noting that this script does not exist anymore in 9.2.0.0. What the script does is basically to determine your kernel version and install the matching kmod version. This can also be resolved manually with the matrix of this page : https://www.ibm.com/support/pages/ibm-mq-replicated-data-queue-manager-kernel-modules.

    Can you send me your document as private reply ? or do you need an email address ?

    Hello,

    There are a couple of ways of configuring HA which are documented here: https://www.ibm.com/support/knowledgecenter/SSFKSJ_9.2.0/com.ibm.mq.con.doc/q017820_.htm. A quick note on RDQM is that it relies on a kernel module to replicate data. You can see supported versions here: https://www.ibm.com/support/pages/ibm-mq-replicated-data-queue-manager-kernel-modules which includes RHEL 7.6.

    Thanks - Amy

    Hello experts. 

    I am new to MQ. I need to pull messages out of IBM MQ (in IBM cloud) into Kinesis Data Streams (in AWS). I have found source connectors for Kafka that can read messages from MQ, but I've no such connectors that can do the same for Kinesis Data Streams. The data out of Kinesis will be further processed down the line within AWS.

    Any guidance towards what I'm trying to do would be of great help.

    Thanks a lot.

    Well, IBM might disagree. MQ itself does not do much. You need applications for sending and reading messages.
    If you are interested in Amazon Kinesis Data Streams why not solve your business case without MQ?
    If you wanted to read messages from MQ and put them into KDS you could work with IBM App Connect.
    KDS provides an API.
    With App Connect you can build interfaces between MQ and Web Services (the API from KDS)
    With some luck there is already a built-in connector available that one could use.
    If not one can write it yourself.
    https://docs.aws.amazon.com/kinesis/latest/APIReference/API_PutRecords.html
    Especially if you are working with IBM App Connect on IBM Cloud the number of built-in connectors is going up quarter by quarter (perhaps month by month).
    At the communities from App Connect or Cloud Pak you might get more suitable replies.

    Thank you very much Matthias for your reply to my query. An application in IBM Cloud is already publishing messages to MQ that I need to bring into AWS Kinesis where other application within AWS will consume the messages. I will study the options you have mentioned.

    Thank you.

    Perhaps it is an option to use ibm mq inside the AWS Cloud
    https://aws.amazon.com/quickstart/architecture/ibm-mq/
    https://aws-quickstart.github.io/quickstart-ibm-mq/
    App1 -> IBM Cloud QMGR -> AWS IBM QMGR -> App2 -> AWS Kinesis
    I would also ask IBM/AWS for advice what the best way is to exchange messages between both clouds.
    Kinesis is not considered to be a messaging system:
    https://aws.amazon.com/messaging/

    Thanks Matthias. This is what the data pipeline would look like.
    App1 -> IBM Cloud QMGR -> Bridge (on AWS) -> AWS Kinesis

    I'm exploring two option for the Bridge - 1.Apache Camel, and 2. PyMQI

    Would you have any preference or recommendation?

    Hi Ashish,

    Welcome to the MQ community :) Matthias is right that you can use MQ inside the AWS Cloud. There are options including running a QM on AWS IaaS yourself (traditional s/w or container deployment) or making use of our MQ managed service on AWS. Either way this enables you to use MQ as a transport all the way into AWS. From there you'll need to make the bridge to Kinesis. The Kinesis connector API is Java so I imagine an MQ application could be written to take the messages and invoke that API.

    Cheers, Matt

    Ashish Naidu,

    You have to use Kafka MQ connectors:

    Take a look on this: 


    Obs.: event Streams is based on Kafka so you can extrapolate to all Kafka products.

    There are  key differences between MQ and Streams products like Kafka.
    MQ is a enterprise messaging middleware. It is intent to enterprise point-to-point messages and publish-subscribe integration models. It enables desired features in pub/sub and point-to-point that doesn't exist or are difficult to implement in Kafka.
    Some competitors of MQ are: AMQ (Apache, RedHat), Rabbit MQ, etc. Not Kafka directly. Which doesn't mean you can't choose between both depending on what challenge you have to integrate apps.
    Streams computing is different, and Kafka is better suite to it. Kafka is a log system utilized to compute on the fly data (streams). IBM has an implementation of Kafka called IBM Event Streams. There are other services implementations of Kafka in the cloud, as well implementations of MQ and other message systems. But Kafka has a extremely difficult implementation to address pub/sub management which is very common in the Enterprise pub/sub area.
    So it is not a matter of one is better than the other.Correct is to say they are focused in different areas: Enterprise middleware messaging versus Stream Computing.

    Hope this can elucidate a bit.
