CU3 for SQL2012 SP1 – Couple of interesting hotfixes.


Here comes CU 3 (Build 11.0.3349.0.) for SQLServer 2012 SP1. You can download the same from http://support.microsoft.com/kb/2812412

Similar to CU2 there are some interesting hotfixes which are included in this CU release, and its worth testing it out.

The ones which attracted my attention are –

2800013

(http://support.microsoft.com/kb/2800013/  )

FIX:   Access violation when you put a FILESTREAM-enabled database offline in SQL   Server 2008 R2 or in SQL Server 2012

 

2803529

(http://support.microsoft.com/kb/2803529/  )

FIX:   Poor performance in SQL Server 2012 when you run a SQL Server trace

 

2807974

(http://support.microsoft.com/kb/2807974/  )

FIX:   Error 3456 after you add new file groups to the principal database in a SQL   Server 2012 asynchronous database mirroring environment

 

2813214

(http://support.microsoft.com/kb/2813214/ )

FIX:   CPU spike when there is no load on a server after you install SQL Server 2012   on the server

 

2819662

(http://support.microsoft.com/kb/2819662/  )

SQL   Server 2012 experiences performance issues in NUMA environments

The last 2 fixes attracted me a lot, however these are type of issues might not occur for all the environments. The CPU spike fix has a situation like a server with 64 or 128 cores +NUMA and 256GB – 1TB of Memory.These specifications are beyond imagination for small environments and majority of the enterprise(As of now !),so these might not even be a concern for the admin’s.

Conclusion

The decision to test or deploy CU3 for SQL2012SP1 varies from environment – environment and your approach towards CUs.

Thanks for reading and keep watching this space for more.
