Failing to restore SQL 2008R2 SP2 Enterprise Edition with CDC enabled to SQL 2012 SP2 Standard Edition
We currently restore a CDC Enabled SQL2008R2 Enterprise Edition backup to a SQL2008R2 Standard Edition server for our OAT, but when I try to restore the same to SQL2012 Standard Edition using the same scripting I receive the error:
Database 'xx' cannot be opened. It has been marked SUSPECT by recovery.See the SQL Server errorlog for more information.
Msg 934, Level 21, State 1, Line 3
SQL Server cannot load database 'xx' because Change Data Capture is enabled.
The currently installed edition of SQL Server does not support Change Data Capture.
Either disable Change Data Capture in the database by using a supported edition of SQL Server,
or upgrade the instance to one that supports Change Data Capture.
My question is, have the restrictions been tightened up for SQL2012?
Thanks

SQL server taking all the CPU and RAM
Dear All,
I have a SQL Server 2008 standard edition with 20 GB RAM and have allocated 17 GB of RAM memory to SQL Server and 4 CPU.
But Since last 1 week i am facing issue in SQL server, The issue is SQL Server reaches 100% CPU usage constantly , have checked there is no single query is running in sql by using below dm views
SELECT Text from sys.dm_exec_request cross apply sys.dm_exec_sql_text(sql_handle)
I have also checked in task manager but only sqlserver.exe taking 100% CPU and Physical Memory Both
Then i have restarted the sql server, during restart process, the utilization gets decreases but Once the service gets started, Again the CPU and Physical Memory reaches to 100 % and it doesn't release the memory.The Only solution which i have used is rebooted
the server, but it would not be the solution because the server is in Production.
I thought there might b issue with the antivirus have disabled it but nothing happend good, also checked in counter and found the total sql server memory(KB) is taking all 20GB and all the counter thresh hold values are normal.
I don't know where is the issue, I would thankful to you guys if someone help me.
Thank you

fragmentation myth
Hi guys,
I wanted to test a couple of things regarding frag/defrag... For that purpose I need a fragmented database... Do you know where can I get a heavily fragmented .bak?
I know I can somehow create fragmentation on purpose, but it would be quicker to have a fragmented .bak that I can quickly restore...
Thanks in advance!
ps: basically I wanted to test http://www.brentozar.com/archive/2012/08/sql-server-index-fragmentation/
I do have shared storage, and I believe I should carefully monitor fragmentation!

Identify poor performance on production environment
Hi Team,
I am not able to understand the root of a performance problem before I can fully address it.
I am working on SQL SERVER 2008 R2 DB. We have transactional DB, wherein multiple user can login and perform operations concurrently.
We have used 'N' number of stored procedures and functions. As DEVELOPER, I want to identify SQL objects which are taking time on production.
I am facing problems like,
1. I don't have access to production DB.
2. On lower environment (ALPHA, BTAT, CERT), we have less data and poor performance is not observed. So I can not use my lower environment.
3. I can not use SQL SERVER trace on production, as it will put load on production DB. (lower region trace is not giving me enough information.)
Can I ask production team to install some free DB performance monitoring tools to install?
What type of information, I should ask from production DB people (as after putting request, they can provide me that details after few days, and asking same type of information again may not be feasible)?
Performance counter use?

SQL 2014 R2 / Recursion Issue
We have several stored procedures that use CTE expressions and are used quite often in our applications. These procedures have worked perfectly for over 5 years on SQL Server 2008 R2. We migrated to 2014 R2 about 5 months ago. During this time we experienced the MAXRECURSION error twice. About a couple months apart.
The errors would generate for all query results regardless of the depth of the hierarchy. We tried troubleshooting by looking at a simple example of one parent record that had one child record. There was nothing special about it and it would generate the same MAXRECURSION error as the others. We spent about 2 hours looking at data. We even edited our CTE queries, setting the OPTION (maxrecursion) value to a very high value with no luck. Then for no reason at all it started to work.
Does SQL 2014 process CTE queries differently than SQL 2008 R2? Could it be a temp table issue? Why would these work for a few months then go down for a couple of hours only to start working again? The SQL Logs show no errors to point us in the right direction.
Any suggestions on what might be causing this would be greatly appreciated.
Thanks...

Release unused disk space
OS: Windows Server 2008 R2 Standard
SQL Server: 2008 SP1 Standard
Hello,
We have a database with about 500 GB of free disk space on data file and the database is being set to read only mode for the fore-see-able future. We would like to release this unused disk space. We know that we could shrink the data file and then work on re-indexing to remove fragmentation. However, we wanted to check if some other method like backup and restore of the database could free up unused disk space in the data file. We do not have an environment to test this process out quickly and hence the question if someone was able to release unused disk space on data file by implementing a backup and restore.
-Jeelani
