custom log provider - not recognised.

Hi All,

I have a tricky one for you...

1. I create a custom log provider on machine A.

2. I deploy the signed assembly to thehttp://DTS/90/LogProviders directory & the GAC on both machine A & machine B.

3. I create a new package on machine A & go to enable logging for this new custom provider: I find it in the drop-down list of providers, and I can add it successfully.

4. I create a new package on machine B & go to enable logging for this new custom provider: I find it in the drop-down list of providers, but I can't add it. I get the following error:

'...failed to create log provider...the log provider type "_" specified for log provider "_" is not recognized as a valid log provider type. This occurs when an attempt is made to create a log provider for an unknown log provider type. Verify the spelling in the log provider type name (package)."

Any ideas anyone?

All I can suggest is to double check the version you have in LogProviders folder and the GAC, and perhaps clean out any duplicate/old versions. Restart VS as well if you make any changes. Seems simple but I know I have confused myself when developing stuff and it has been redeployed after some changes.|||

Many thanks for responding Darren. Both your suggestions are sound, but unfortunately they aren't applicable in this case: in order to rule out any problem introduced by my own work, I tried the same with HtmlLogProviderCS - one of Microsoft's own custom log providers, included in their samples - and I recreated the problem exactly. I didn't change the version and it wouldn't have existed on my machines beforehand, so it's definately something else. In essence, there is a problem in deploying the signed assembly of a custom log provider, onto any machine on which the library was NOT built. (Depending on your level of curiosity, perhaps you might like to try the same with HtmlLogProviderCS yourself?). I might contact Microsoft directly on this one, as I fear it may be a bug.

Thanks again for your input. I'm enjoying the book (am returning to it again & again!), and will let you know if I reach a definate conclusion.

Cheers,

Tamim.

I figured it out!! Basically the error message means that it couldn't find the custom object's DLL in the GAC, and the problem was that I drageed-&-dropped the library into the GAC, across servers - i.e. from a location on server A to the GAC on server B. This looks like it has worked, but in actual fact it didn't. When I remoted onto server B & opened the GAC up locally, it wasn't there. The solution therefore was to drag-&-drop into the GAC on server B, from a location on server B. But now for a tantilising follow up...

...my custom log provider opens up a client-side channel to a remote server, and sends messages into it. When I run the package from the package store it works, but when I run it from within a job the job succeeds and throws no errors or warnings, but the remoting bit doesn't work. I had added my remoting client-side configuration information into dtexecui.exe.config, but I'm thinking that when I run it from a job, I have to add the same config info into another config file? Any ideas anyone?

Hope the partial step forward is of use to someone...

If you have configuration info, then you need some more files, as the UI host is not the same as used when scehduled.

Try dtexec.exe.config and dtshost.exe.config, also in C:\Program Files\Microsoft SQL Server\90\DTS\binn
