Hi All,

I need your help to create subscription type API in IBM MQ v9.*. As documentation says API: Subscription created through an MQSUB API request.

I am not sure how to use MQSUB API to create subscription.

Any help will be highly appreciated.

 Thanks

Hi Hosh,

You should review the code in the IBM-supplied sample amqssuba.c and run the same compiled sample amqssub. This uses MQSUB and will create a SUBTYPE(API) subscription. Here is an example invocation, where MQG1 is my queue manager name.

amqssub Test MQG1

Bear in mind that this subscsription is not given a subname and so when you display it, you will see a blank name for the SUB.

Cheers,
Morag

Hi Hosh,

To add to Morag's suggestion, if you want subname you can use amqssbxa sample.

Excerpt from amqssbxa.c sample source code:

AMQSSBXA has the following parameters                         
    required, at least one of:

This approach has been effective, and I appreciate your help. However, I've encountered an issue during the queue manager migration process. It appears that the API-type subscribers, specifically those with a subtype of "API," are not getting migrated successfully. Do you have any insights on what might be causing this issue?

Thanks

Hi Hosh, 

Could you please share the migration steps and the type of subscription (durable or non-durable) not getting migrated.
