SQL Server 2014 32 位在 Windows Server 2012 R2 中升级 64 位

Question

I am running SQL Server 2014 standard on Windows Server 2012 R2 machine.

I installed sql server by Install link

But i problem is the sql server is running 32 bit on my machine (14 core Xeon and 64 gb RAM) and consumes a lot cpu is very high (some times 100%) but ram 16 gb only It is also an issue for IIS 8.5. I suspect that 32 bit installation may cause the problem. WHY it takes so much CPU for Sql server and IIS? and how to convert it to 64 bit of Sql server and IIS 8.5?

Answer 1

Offcourse you need to install a 64 bit instance of SQL Server. I think you made a mistake by downloading the 32 bit version of SQL Server?

I think the biggest problem with SQL Server 32 bit is that SQL Server can only allocate 2GB of memory. So the rest of the 14GB isn't used at all by SQL Server. In many cases this will cause a lot more disk reads because the database buffer cache can't hold a lot of pages in memory.

My first suggestion is to install a new instance of SQL Server (64 bit) and migrate these databases. It's not certain you're CPU "problem" (50/60 avg isn't really a problem) is gone after this upgrade. But this will be a big step.
