IA64 support for ia32 applications on windows enviornment

[sreeramam]

We want to install 46b / mssql 7.0 on IA64 MS-Window for IA64.

We want to know weather ia32 bit applications are supported on ia64 bit CPU with IA64 - bit processor.

I don't think this will work at all...

There is NO way that SQL 7.0 will even know how to use a 64-bit architecture since it was designed purely for 32-bit.

Also keep in mind that SQL 7.0 is old and now in "Extended support" period.

Go for a supported version like SQL 2005 64-bit for Itanium

Remember that IA64 focuses on security/fault tolerance/uptime compared to x64 that focuses on performance.
64-bit apps for IA64 are NOT compatible with 64-bit apps for x64 - remember that if you read just "64 bit" as that basically is not specific enough.

Further 64-bit vs 32-bit the main advantages of 64-bit comes with applications that need and use large amounts of RAM. If your SQL 7.0 is a small db with little RAM use it will actually run better on 32-bit servers.

Technically any 32-bit application will only be able to run on IA64 Windows via a 32-bit software emulation layer that has serious performance disadvantages. So, the recommendation is to use only native IA64 applications on the IA64 platform.

In the above string you mentioned abt
32-bit software emulation layer. Kindly suggest how do we procure this 32-bit software emmulation layer for IA64.

Our whole problem is we do not have ia64 compatiable version of SAP 46b mssql.

kindly suggest further.
