WD Java RFC metadata cache invalidation without recycle JAVA

Former Member
0 Kudos

Since we are in a high availability production system, we cannot recycle or CE instance. There are times were the RFC metdata invalidation does not work and the only things that forces it is a recycle of the CE system.

This is contrary to what SAP has publicized, so is there a process in NWA or a single process (and NOT the server0 process) that we can refresh without stopping and starting the java engine.

Much like Visual Administration is there a single service we can stop and start to ensure the engine stays up and running and available?

Thanks

Hi Weyland ,

did you check the guide ?

Metadata Cache Invalidation for Adaptive RFC Models

http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/10465350-b4f5-2910-61ba-a58282b3b...

There's a solution in this guide which explains how to proceed to avoid engine restart in case of ARFC.

(I don't know your engine release, but if it is >= 711, then you may welcome this guide as well:

Using an Adaptive RFC 2 Model in Web Dynpro Java

http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/50f7192d-2808-2d10-189b-df3fa5f71abf )

I hope this helps.

Best Regards,

Ervin

Ervin, This does not seem to work on NW 7.01 SP 05, even after upgrading JTECHS and JTECHF to the latest patch levels.

I currently have an OSS message open about the ARFC Cache Invalidation tool as it does not work on NW 7.01 SP 05. We were told to upgrade the JTECHS and JTECHF SCs to their latest levels to fix the problem, which it did not.
