Clustering: No ContentData value exists

targa2000

I have an Alfresco cluster set up with 2 servers. I create a document on one and I can see it on the other. I can access the newly created document on the server it was created on, but when I try to access it on the 2nd server I get the following error:

org.alfresco.error.AlfrescoRuntimeException: 08080084 Error during download content servlet processing: No ContentData value exists for ID 8441
caused by:
org.springframework.dao.DataIntegrityViolationException: No ContentData value exists for ID 8441

try rebuilding your indexes. This error comes from corrupt index information.

afaust

We have just experienced a similar error in the production system of one of our customers and according to the investigations into the source code, this almost always is a consequence of invalid data in the 2nd level cache (ehCache) due to improper cluster setup / non-clustered operation with 2 servers accessing the same database. Corrupt indices on the database, as the previous poster suggested, are the 2nd most, but generally significantly less likely cause (provided you use a stable, production-grade RDBMS version and do not fiddle with the data manually). Make sure you have your cluster set up properly if the error persists after you tried rebuilding the indices.

Thank you for your post!

Make sure you have your cluster set up properly . . .

I suppose this is the real question. How do you set up the cluster properly? Can you or anyone point me to proper configuration information?

afaust

The definitive guides / documentation should be these two wiki pages (in that progression from "simple to understand" to "more extensive"):

Configuring_JGroups_and_Alfresco_Clusters
Cluster_Configuration_V2.1.3_and_Later

I just ran into similar issue, if it's not too late. Take a look at these two reported issues:
https://issues.alfresco.com/jira/browse/ALF-2719
and
https://issues.alfresco.com/jira/browse/ALF-726

I hope it helps and I hope the workarounds work for me.

I just got this error on a 5-machines Alfresco Enterprise 3.3 cluster that was working correctly.
Maybe because all machines were restarted while a bulk import was running?

I guess it is not a cluster architecture misconfiguration, as the cluster had been working before the restart.
The error still appears when doing a full rebuild of indexes: "Reindexer 1 failed with error: No contentData value exists for ID 668254".
