Always ON Availability

  • Hi

    I installed 2 node Windows 2008 cluster(32 bit) and installed sql2012 on both nodes.I tried to enable always on feature from configuration manager but I got message that you need non-wow or 64 bit EE of sql version.

    What is wow and how I can trouble shoot this issue

  • Checking the AlwaysOn pre reqs and restrictions cites this

    Ensure that each computer is running either x86 (non-WOW64) or x64 Windows Server 2008 or later versions.

    WOW64 (Windows 32-bit on Windows 64-bit) does not support AlwaysOn Availability Groups.

    Basically if you install 32 bit SQL server on 64 Windows OS (Windows on Windows) this is not supported!
