Solace Community is getting a facelift!
On March 3rd we will be starting the process of migrating Solace Community to a new platform. As a result, Solace Community will go in to a temporary read-only state. You will still be able to come onto Solace Community and search through posts to find answers, but you won't be able to ask questions, post comments, or react in any way.
We hope to have the migration complete by Wednesday March 5th (or sooner), so please keep an eye out!
How to empty a queue with 200+ messages?
Hi all,
We are using Solace in combination with Boomi. We're looking for a solution to empty a queue quickly. No matter how many messages are in that queue.
From the Solace Cloud console, the max is 50 per page. JMS Toolbox is refusing to empty a queue when it contains 200+ messages. How to solve this? Ideally, we would like to have a button in Solace Cloud to do this. For example, today, we have been testing with 3000+ messages. It would take 60 clicks in Solace Cloud to empty the queue. Not really efficient IMO.
Thanks!

however, you can achieve this using the SEMP V1 API.
Yup, you can do with a single HTTP POST!
Otherwise, you could also just drain the queue with a standard consumer app. But that kind of blurs the line between "messaging app" and "management utility".

Hope this helps
RichardThat's an acceptable workaround. Btw: what's the priority of this feature? It's one of our top 3 admin feature requests in the Solace Cloud UI. Others are
- moving messages from a queue A to B. For example, moving messages from a DMQ to the originating queue
- view message payloads => this is the number 1

RichardHi Richard,
I have tried it from Postman using a POST {{url}}/SEMP and the following payload:<rpc> <admin> <message-spool> <vpn-name>my VPN</vpn-name> <delete-messages> <queue-name>my queue</queue-name> </delete-messages> </message-spool> </admin> </rpc>
I get an HTTP 200 OK response, but nothing happens. If I send an invalid XML payload (removing a tag), I still get an HTTP 200. The documentation says:
_An HTTP response of “200 OK” is returned if the command was accepted by the event broker (even if it was not successfully executed).
_How does the SEMP V1 operation work?

It could be an error returned from the broker, such as invalid queue name for example. Try running curl with verbose -v option. Feel free to send me the output in a private message and I can take a look.
In terms of the other requests, there is a tool for resending queue messages, such as from a DMQ, you can try here
For browsing queues and viewing message payloads, I used SDKPerf with options: -qb -md -q

Cool tool @rlawrence! I didn't know that existed. It might be worth making a separate post in the community about it with a title that folks might google search for so it's more easily findable.

I'm missing the cli for that task :-)
ena admin message-spool message-vpn my_vpn delete-messages queue my_queue home exit
(if you compare, that's the direct translation between SEMP and cli)
The bad thing: There is no easy way to reach cli on a solace-cloud instance :-(

Hi @rlawrence and @Aaron ,
Is there an update regarding this feature request for the Solace Cloud UI? Thank you.

Hey @sjaak! Welcome back. I'm not sure, I'll go ask. Actually, I'll go test...
Well, good news! This option is now available in my 10.4.0 broker:
Not sure exactly when they added it, would you like to know what the min version is?EDIT: it was added in 10.0.1. But never release noted. So it's been in the product for about half a year now.

HI @Aaron, thanks! 👍️ Btw: we are using 20+ Solace Cloud services. And Solace is, as we speak, upgrading them to 10.0.
🤔 The newest service we created last week is 10.2. I don't know when 10.4 will become available for upgrades.It works on 10.0.x Solace Cloud. Cool! 😃

Nice! For completeness, this feature was added in 10.0.1, but it's not in 10.0.0. The latter would have been a Preview release anyway, and Solace Cloud would not upgrade to that. 10.0.1 is an LTS version. All Solace Cloud production brokers should be on 10.0.1 or 10.2.1; 10.4.1 Cloud upgrades are currently scheduled for August. See: https://solace.com/support/support-dates-for-release-versions/
Glad it's working! Sorry we didn't ping this thread to let you know.
