No Adapters visible - no connection to Adapter Engine

Question

Hi - again i start a post.
We have problem that we have no adapters in CC-Monitor but Adapter Engine status is green.
Therefore we treid to refresh Cache which run fine, except when we Go To --> Adapter-Engine-Cache - nothing is shown.
In Integration Diretory we get error like:
Unable to contact Adapter Engine "af.px1.sapru03" that is affected by the data changes
http connection to "http://sapru03:50000/CPACache/invalidate" returns the status code "503" in response
and for Java Cache:
Unable to notify integration runtime (Java) of data changes
http connection to "http://sapru03:50000/run/value_mapping_cache/ext?method=invalidateCache&mode=Invalidate" returns the status code "503" in response
We already checked user in SU01 if locked, but is not.
When trying to access cache via http://host:port/CPACache/refresh?mode=full
we receive an 403 with PISUPER oder PIISUSER.
Can somebody help how to register Adapter Engine perfectly?!

Answer 1

Hi, ok i read this before.
1. We have no PCK installed so no need to undeploy.
2. CacheType Property is set to DIRECTORY and uses PIAFUSER as user (is this right?)
3. We get http 403 while calling <http://<host>:<J2EE-Port>/CPACache/
4. For calling /CPACache/refresh?mode=full we get following error (let me tell you that this is first time this call runs and gave back information!):
Negative confirmation:

5. While calling /CPACache/refresh?mode=full|delta we receive a http 500 Internal Server Error
