OS 64 Bit, SQL 32 Bit

  • Hi All,

    i have a scenario where in the Operating System is Windows 2003 R2 Datacenter X64 bit edition service pack 2 and SQL is of 32 bit Standard Edition (In Database Server). Application side we have Operating System is Windows64 Bit Edition with Service Pack 2. I would like to know will there be any issue in handling the requests from SQL Server side.

    With Regards

  • No issues, but you're going to have all the 32-bit memory limitations. Why not install 64-bit SQL?

  • Thanks for the quick response.

    Sure we will install 64 Bit SQL, but wanted to know will there be any major impact in serving the requests from the application side. Because its a production environment where we have 32 Bit SQL with 64 BIT OS.

    We are planning the migrate to 64 BIT SQL, wanted to know if any major impacts in serving the requests.

  • Shouldn't be any issues unless you're using linked servers with 32-bit drivers.

  • In addition to Linked Servers (including adhoc uses via OPENQUERY, OPENDATASOURCE and OPENROWSET) calling an external app using xp_cmdshell can be affected if the called apps cannot run in a 64-bit shell. If you're using SSIS on the server any data access drivers can become an issue as well of which upgrading to use a 64-bit Excel driver is a common need.

    From the client-side though, in terms of remote clients connecting to the instance, the change to 64-bit should not be detectable.

    edit: should not be
