My company successfully has been using MaxDB (asd the database backend for things other than SAP) for the last five years, and I've been consistently impressed with its performance and stability. So far, we have been running it in a non-high availability configuration, but now we are looking to improve availability to an even higher level by looking into a high availability configuration.
Specifically, I have been looking into the hot standby setup, where a master and several standby instances run in a clustered environment with automatic failover. The system requirements for this at http://maxdb.sap.com/doc/7_6/d2/08d43f2dd44821e10000000a1550b0/content.htm mention that you need cluster software and a memory management system. I have access to a storage area network (though not managed by one of the products listed on this page), which hopefully should do for memory management, However, I am wondering about the cluster software requirement. The page lists an IBM AIX product as the only tested cluster software package. Does this mean that MaxDB hot standby configurations only run on AIX, or would using UltraMonkey (www.ultramonkey.org) or some similar HA solution for Linux also work in this capacity?
Any and all insight from people running hot standby configurations would be most appreciated.
