I have received an update that DAM cluster now need at least 3 nodes (manager, member and redundant) and no more active-passive. But I can't find in the documentation.
Anyone can tell me where to check that info?
Thanks so much everyone!
Dear Long,You can still use the gateways as Active/Passive until you configure the cluster. The requirement which you are mentioning is for clustering.More details can be found at the cluster concepts.https://docs.imperva.com/bundle/v14.9-database-activity-monitoring-user-guide/page/6516.htm
https://docs.imperva.com/bundle/v14.9-database-activity-monitoring-user-guide/page/6518.htmHope this helps, For migrating normal gateways to cluster we can use below guide,
Could you please help to provide Active/passive configuration?
Just a quick details about on gateway configuration (Without cluster):
Gateway Group Setup:
For more info on agent failover, check out this article: Agent Failover Process.
Thanks for the revert,
Belong to your response, then I can still config 02 DAM Gateway Appliances as Active/active or Active/passive?
I was also told that DAM Agent HA is no longer supported. We should use cluster instead. I am wondering why DAM agent HA is not supported anymore? We have many customers with HA configuration. Many of our customer still need HA that is good enough for them. Migrating cluster will add cost as it requires cluster license.
I was also told by Imperva SE that supports our area that should be at least 2 + 1 (2 active members and 01 redundancy). Cluster with 02 member only will not work properly or stalely (1+1 cluster may not support fail over). I tried to search in Imperva document for this note (cluster must be at least 2 + 1) but didn't find this. We have tested cluster 1 + 1 in our lab and it works
My question is that, by design does Imperva DAM cluster support 1+1? if not supported, where can I find the note in Imperva document?
I read on document then we still configure active cluster, backup/ passive cluster:
