Queue Consumers failing when error in payload

Khonzi Houdini 1 year ago in Studio / Sources updated by Wynand Vermaak 9 months ago 5

Service is launched successfully and consumers connected to queues. However, after around an hour or so we would find that the consumers on the journey.welcome.request queue would disappear however the other journey queue were reflecting the consumers fine.

What we found was the queue worker process would die (as per screenshot) the only way to get the consumers back was to restart the warewolf server service

What we tried to do was to increase the concurrency to 3 and set the prefetch to 1, and we still experienced the same issue

On deeper investigation it appeared that if the message being process was unable to reach the external api’s for any reason for instance the product api, it would kill the consumers, we tested this by correlating the timelines of when the “product” api was available to when the consumers disappear.

Once we had the “product” api stabilized consumers were stable and remained present

So appears to be a bug with the queue worker when it is unable to process the message correct caused this to crash

My understanding of this is:

  • Error was experienced during processing of the message
  • That message which is an unack message with the error did not leave RabbitMQ due to the fact that it never received an ack back from warewolf.
  • RabbitMQ did not allow additional messages to be processed due to not receiving the ack back (aka message stuck)
  • Appear to be the way that warewolf error handling works where it does not send through the ack even if an error was experienced with the message.

Connector SQL Server ERROR ExecuteXMLReader

Michael 6 years ago in Studio / Sources updated by Elmo 6 years ago 6

Hi, 


I have a problem with the stored procedure on the MSSQL server. I did it the same way as in the tutorial PDF, but with a different database. When I want to debug the flow, I only get the following error message: The command sent to ExecuteXmlReader is invalid. The command must return an XML result.


Thanks in advance.

Hi,


The databases are limited to the databases that the that you have logged in with has access to, using the following command


SELECT DISTINCT(OWNER) AS DATABASE_NAME FROM DBA_SEGMENTS WHERE OWNER IN (SELECT USERNAME FROM DBA_USERS WHERE DEFAULT_TABLESPACE NOT IN ('SYSTEM','SYSAUX'))

I am fairly new to the Microsoft experience, but was wondering if the DLLs have to be C# or can they be VB to use in Warewolf? Can I create objects in the DLL and access them from Warewolf ?

Warewolf support of DB servers

Anonymous 10 years ago in Studio / Sources updated by Gandalf 9 years ago 4
Hey guys,
I just have a random question. Does Warewolf cater for non-SQL Server DB servers like MySQL and Oracle?
If it doesn’t can you please just explain why?

Thanks :)
Answer

Hi Anonymous

Warewolf is designed to cater for any database. We haven't had the request from any clients (or any additions from the community on GITHUB) for anything other than MSSQL yet. The plan is to implement Oracle, MySQL etc. as soon as there is a demand.

Let us know if you need something prioritized.
