Обсуждение: Microsoft Cluster for Failsafe
Hello,
I am new here and have got a general clear question:
We are working only on base of microsoft OS, and am thinking of installing Postgres 9 on a 2 node microsoft cluster as a failsafe solution.
Can I do that, using a builtin feature of Postgres, or is there an extra software I can use?
Many thanks in advance

PostgreSQL 9.0 or higher is all you for a 2 node cluster. PostgreSQL 9.1 is available next week and you should start with that.

PostgreSQL has worked fine with the 2 node MS failover cluster since the first native version on Windows, which was 8.0. You need no extra software, and yo udon't need PostgreSQL 9.0 for it. I share Simons recommentation that you *should* use PostgreSQL 9.0 or 9.1 though ;) And it also gives you other ways to build the availability solution than the MS cluster one. > Good luck and welcome to Postgres. +1 :-) -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/
Thanks for the prompt response, Good to hear that, but really I cannot find a document how to configure Postgres as Failover on a 2 node MS cluster (onedata store which could be owned by one node at a time and two Postgres Instances on both nodes one is active and theother is passive, just like oracle Failsafe on ms cluster), the available documentation is only mentioning the Replicationand standby are the only choices for Postgres High availability and Clustering-Failover not.

You set it up like a "generic service" I think it's called in MSCS. In a group along with the storage resource and the IP address. And make sure you have all your postgresql data on that disk. How that's done should be in the MS documentation. This is not a PostgreSQL feature really, but one of MSCS, that's why it's not included in the PostgreSQL documentation. What we have is at http://www.postgresql.org/docs/9.0/static/different-replication-solutions.html, under "shared disk failover" - that's the MSCS solution. -- Magnus Hagander Me: http://www.hagander.net/ Work: http://www.redpill-linpro.com/
