Queue Consumers failing when error in payload

Khonzi Houdini 11 miesięcy temu w Studio / Sources Ostatnio zmodyfikowane przez Wynand Vermaak 6 miesięcy temu 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 lat temu w Studio / Sources Ostatnio zmodyfikowane przez Elmo 6 lat temu 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. Why when I create Oracle database source the database choices are limited to HR, SCOTT, OE, PM, SH and IX

There should be user that i create as database. For example, there be include 'SPBO2' as if in normal oracle query it will be SELECT * FROM SPBO2.TABLENAME

Thank you

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'))


Thanks

VB DLLs and Objects

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

Anonim 9 lat temu w Studio / Sources Ostatnio zmodyfikowane przez Gandalf 9 lat temu 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 :)

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.
