Oracle Analytics Server Achitecture

Tiang

Hi,

Setup Info:
2 Node (Oracle Linux Server 7.9)

Oracle Analytics Server 7.0

Node 1 and Node 2 setup OAS and setup as High Availability

Follow Official Document setup NFS shared storage and configure SDD and other component files stored inside.

Question:
In a scenario where OAS Node 1 or Node 2 is non-operational, the remaining node continues to function and provide service continuity. However, if the NFS shared storage server experiences a failure, it will adversely affect the OAS services on both nodes. Are there any best practices or recommended configurations to mitigate this risk?
Currently, the NFS server is deployed on a Linux server, serving as a file storage solution, and is mounted on two separate nodes.

Thanks.

To add, depending upon the level of "HA" you need, you can follow the recommendations or specific architectures as described in the Enterprise Deployment Guide, including About Using Redundant Binary (Oracle Home) Directories

See Chapters 4 and 7

Hi,

The shared storage can be various kinds of solution, NFS is one example. I imagine that the idea, if using NFS, is that it does come from some kind of enterprise storage solution. One of those that just can't go down because it has redundancy everywhere (drives, host, power, network etc.).

The architecture leave it fully in your hand to find a way to make sure you can provide a shared storage on all nodes. There seems to be way to create a high-availability NFS server. There can be different shared, high-available, storage solutions that you can use to make sure your storage is available.

All in all, it's in your hands to evaluate how much you want that shared storage to be available, and design a solution that match those requirements. All that OAS needs is just a "local" folder that is in sync between all the OAS nodes. How you achieve it, that's up to you.
