SQL Server 2012 HA on Server 2008 R2 vs. Server 2012

Posted: 16 May 2013 03:10 AM PDT

I am planning for the update from SQL Server 2008 R2 to SQL Server 2012. I've read some accounts of differences between running Always On and WSFC on the older version of the OS vs. the newer. NB: I *am* trying to get a comment on this directly from Microsoft, but they're not being responsive so far. I am alo taking a Microsoft training course that purports to cover HA, but the references are superficial re this question.The concerns revolve around updates to the database(s) on the servers in an Always On Availability Group. Are there substantial differences between the steps to patch SQL Server 2012 running on multiple machines supporting multiple DB's when it's running on Server 2008 vs. Server 2012? Our primary enterprise application, which would *definitely* be in an Availability Group, gets 4 business critical updates a year. Two of those are often taken under operating season pressures such that I don't want to add complexity that could be avoided. Are there substantial differences between the steps required to install and promulgate a new DB version under different versions of the server OS? Note that, in all cases, the Availability Group will host at least two databases, but that only one of them will require major updates.Does anyone have enough hands on experience with AlWays On and WSFC to venture ideas? Any suggestions on where (official Microsoft?) sites/blogs/????) I might try for an authoritative answer?

Audit the Audit settings changes

I have a requirement from my customer to enable auditing, few at the server level and few at the database level.I have been successful in enabling the audit.Now, I have a question of we can audit the changes in the auditing configuration itself?For example..If someone deletes a particular setting in the audit properties, I want that to get logged too.Is it possible.

Question regarding staging tables and fact tables for a Data Warehouse in a sql server 2012 database

Posted: 15 May 2013 04:27 AM PDT

So I have a staging customer table that holds combined customer information for several different databases. All our customer information across different platforms is combined and standardized in this staging table. Based on this data - we normalize it and then either update the customer information in our Fact table if that customer already exists - or we insert a new customer record if that customer doesn't exist. Our current Fact table has 10+ million records in it. Our staging customer table has millions in it as well. I know these numbers aren't exactly big - but I am also planning for the future as well. So - my question is are there any 3rd party tools on the market that can help with the update and the inserts? Or is my only option scripting it all out in either a stored procedure or an SSIS package. I looked at Red gate's SQL compare - but it looks like it works better if you run it ad hoc. I am looking for something to create and then schedule it so it runs automatically. Any suggestions is greatly appreciated.
