Hotfix C installation on 16.2 / serialization policy file

Hello,
we faced the same problem as kaushikr735 on 19.7.2016.
Tempo was not available after the Hotfix installation.
We copied the file "/tempo/D68677DEE20974ADA7AA9FDE366ECD52.gwt.rpc" from our backup folder to our new appian instance and restarted JBOSS afterwards to fix the problem.
But why we had an issue in the first place? Is there something wrong with the hotfix or with our installation ? 4 Weeks ago we made an upgrade from the version 7.8 to 16.2 without any updated in between.

Thanks
Yusuf

Actually that's not the right solution and can put your system in an inconsistent state.

The right solution is described here forum.appian.com/.../kb-1058.html

Question @eduardo, the KB suggests to copy over the full contents of the war dir, which is essentially what I've always done. However the IIS and Apache docs say to only copy certain file extensions over to the web server. forum.appian.com/.../Configuring_IIS_with_JBoss.html Any real reason why it would say that over copying the full war?

You can configure the extensions that should be served by IIS/Apache in "uriworkermap.properties". The KB suggests copying all to ensure that everything, regardless of the configured extensions (which may differ between environments) is available. If disk space is a concern, as long as you copy over all the files with the extensions listed in your "uriworkermap.properties" you shall be fine.

Hi Eduardo, we're facing the same issue after applying Hotfix H to a perfectly working 17.1 environment. The solution you gave in your post is no longer accessible due to forum migration to the new community platform.
Can you help me out with the issue?

This is the error:

[org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/suite]] (ajp-/0.0.0.0:8009-1) tempoSvcServlet: ERROR: The serialization policy file '/tempo/4054428C5DBBCAA1F3B77E9C975766CB.gwt.rpc' was not found; did you forget to include it in this deployment?
13:20:28,654 INFO [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/suite]] (ajp-/0.0.0.0:8009-1) tempoSvcServlet: WARNING: Failed to get the SerializationPolicy '4054428C5DBBCAA1F3B77E9C975766CB' for module 'http://*****/suite/tempo/'; a legacy, 1.3.3 compatible, serialization policy will be used. You may experience SerializationExceptions as a result.

After this the Tempo interface is no longer accessible.

Sites are working fine.

Thank you Carlos, but I did copy the content twice, event after applying the hot fix a second time. Also cleared Jboss cache to no avail.
Still stuck with the same error...
