"Microsoft Active Directory Adapter" - best way to handle loads of requests

Hi

We have a solution where we via a File Adapter publish a large amount of "AD Update" messages (>500) within seconds and they are subscribed to by the "Microsoft Active Directory Adapter"

Our Active Directory is not happy with so many requests sent in a few seconds and many requests time out.

We are thinking of ways to handle this and were hoping for some good thinking from fellow Neuron developers:

1. We could add all requests ton a table and then read them at a reasonable speed, and then send to AD Adapter. 

2. We could work with "Retry Count" and "Retry Interval" on Adapter Policies, so requests that timeout are sent again eg. 1 minute later.

3. We could try using MQ for the solution.

4. Something else?

Any ideas are very welcome ;-)

Regards André

Hi André

I would also look into throttling. As I read it this is what it basically is about and what is causing the timeouts.

Under the Networking Tab for the Topic you can specify Publish Throttling and specify Messages per second, Messages per Minute, KB per time etc. Sounds like 10 messages per second could be a way to go, but this is usually a case of experimenting a bit and seeing if the server can handle the load.

I bellieve that the throttling setting should solve it for you.

Otherwise, you can also set more detailed restrictions on the topic in the Properties Pane such as:

- Allow Output Batching (set this to False)
- Max Concurrent Calls
- Max Concurrent Sessions
- Max Concurrent Instances
- Max Connections (could also be set to 10)

Best regards,

Christian

Excellent Christian

Throttling was just what we were looking for.

And can see that it works very well after a small test.

Thx

André

Hi,We are using the Marketo adapter to push account updates to Marketo. It works well for some time then starts failing with Invalid Token unless restarted. Is there a configuration that can be done so it can auto refresh the token when required?Thanks!See More

ODBC stored proc polling with temporary tables

We have set up an ODBC adapter to poll a stored proc.We found that if the stored proc has a temporary table defined the rows returned are always 0.Any idea why this would be and what we can do to get around it?See More
