500 Internal Server error for WD applications

[Former Member]

Dear All

I have a very strange situation and I don´t have any idea of what to do.

Basis took the backend R/3 system down for some reasons and made it up again after some time. But now they have locked all users in our backend R/3 system as Basis is performing some task on the server.

This has resulted in all web dynpro applications that are using RFC's throwing 500 Internal server error.

All other web dynpro applications that are not dependent on R3 system are working fine.

We also have restarted the EP server as we deployed one WD application.

I'm not sure how the situation was before the restart of EP server.

In NWA i can see many error for ACCESS.ERROR: Authorization check for caller assignment to J2EE security role referencing J2EE security role .

Also

application Processing HTTP request to servlet finished with error. The error is: com.sap.tc.webdynpro.services.exceptions.TypeNotFoundException: type is.eimskip.keywordsearchmodel.types.Zotkey could not be loaded: com.sap.dictionary.runtime.DdException: failed to create provider: User is locked.

I believe that error will get resolved once the users are unlocked in R/3 system.

But the stituation is, we will get the system back on monday morning and I'll have no time to do anything as the business will be back in 1 hr when we get the system back.

Can you please help me to identify the tasks that I can perform and be sure that all will be normal on Monday (and I'll still be in job.)

Request your help and support.

Thanks

Vineet

Looks you have problem in JCo destionations.

could you test JCo connections in

http://<server>:<port>; -> WebDynpro -> Content Advisor -> Maintain JCo Destinations

under the project you get your JCos

Hi

Thanks for your reply. But this is not the solution to my actual problem.

R/3 server is down and is not accessible.

I can not check anything via logging in to the R/3.

Hi

Our R/3 test and R/3 production system both are down.

But our EP test server opens the WD iView successfully whereas our EP production system shows 500 Internal server error.

Can you help me with it.

[nikhil_bose]

are you sure that the DataBase is running ?

if not, run DB service first and start J2EE engine.

Hi vineet,

Check the following things:

(1) Specify the user names in Capital letters and try. This will help you. (this could be the problem)

(2) Test the RFC destination using the tCode SM59 and try to remote login from there.

(3) If the user is locked, you can unlock using the tCode SU01.

Regards

Vinod V
