DB changes in one cluster node is not reflecting other node.

[Former Member]

In our application cluster environment has 4 storefront node and one backoffice node. Currently we are facing issue like that when we are updating any data from backoffice node , update is not reflected in storefront until we clear hybris cache manually. Cache invalidation is not being done. But update from other node is reflecting other nodes. Backoffice node is also in cluster and jgroups. Could you please advise what might be the reason behind this. This issue suddenly appeared. Earlier it used to work as expected.

Hi

Any luck in resolving this issue? we are facing a similar issue and using Jgroup UDP connection.

Maybe network issues which block the invalidation messages? Changes in firewall between the nodes could be an issue.

How to check network issue. Is it possible to enable logs and get logger for invalidation message. We are using UDP connection. How we can debug this issue.

You can verify easily if it is a network issue by testing that regular invalidation works. Open backoffice in two nodes Make sure to open the same product (for example in both systems) Update the product in one of the nodes and save Refresh the product on the other node

Expected result : product is updated

I have experienced as well that the update is not coming through. And a restart has most often been done.
