I have a database that is the publisher in transactional replication and also part of an availability group. I have put the pertinent certificates on all of the involved servers, and it is encrypted on all servers and operated as expected. However, we are adding additional security for personal data and we have targeted columns in multiple tables for column encryption. I have a master key and certificates that are stored in the master database. Following an example where I am to create the database master key:
-- Create database Key USE encrypt_test; GO CREATE MASTER KEY ENCRYPTION BY PASSWORD = 'Password123'; GO
But when I try to create a certificate on the database:
-- Create self signed certificate USE encrypt_test; GO CREATE CERTIFICATE Certificate1 WITH SUBJECT = 'Protect Data'; GO
It get the following: Msg 15151, Level 16, State 1, Line 1 Cannot find the certificate 'Certificate1', because it does not exist or you do not have permission.
Can I add a database certificate to an already TDE enabled database and if not to I create the symmetric key through the certificate located on the master database? And how will that effect decrypting the column values in stored procedures and function on the user database?
Some file names listed could not be created. Check related errors.

I did not have remote connections enabled yet, so the resolutions I have found that include sqlcmd or starting in single user configuration are not working. Any way that might allow me to restore the usual tempdb settings, which I think would allow SQL to start again?
If one is regularly taking backups of system databases, when does it become necessary to rebuild the master database. I am looking for a situation where rebuilding the master is preferred to restoring it from backup.
Is it possible to put master database to single mode, if yes then whats the procedure. The reason behind the scenario is to restore master database from backup for which its strictly recommended to put the database in single mode. But I m not able to do so.
Sometime during the night last night some user account permissions were "lost". Am I right to think that restoring the master database would be the way to go? We have a 2 node 2012 cluster and I stop the cluster resource and start the db in single user mode from the active node. Somehow the sharepoint farm is still trying to connect so I can't get logged in single user. What method could I use to stop users from connecting when I don't have access to the sharepoint farm.
I am working on a Login migration issue. I have the Master database from the original database, that I have attached as a User Database, call it OriginalMaster. I also renamed the mdf and ldf files, before attaching, just in case.
I want to select the logins from the OriginalMaster, and using sp_help_revlogin script all the Logins out. I know there were many logins in that database. But what I am seeing, are all the Logins from the Current Master database. Which are only 7 Logins.
How can I select the logins, or script out the Logins from the OriginalMaster database?
encrypting a column in a sql server database. I have userid and password columns that I think should have protection on them. My thought was to encrypt these 2 columns. What happens if someone needs to know the actual values of a userid and password? Is encryption the right way to secure this data?
I have a install of SQL 2005 that is about 5 months old. The tempdb.mdf and master.mdf files have ballooned to a huge size almost filling my hard drive. How do I reset them to a reasonable size?
I used the selfssl.exe tool to generate a certificate on my db server, successfully added to Personal Certificates in MMC, added R/W permissions for the service account to the cert, selected the new certificate in the protocols for mssql and restarted the service. So far so good, however when trying to connect from SSMS with encryption check box checked I get the following error:
A connection was successfully established with the server, but then an error occurred during the login process. (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server, Error: -2146893019)
The certificate chain was issued by an authority that is not trusted.
When I look in MMC, the only intended purpose for the certificate is "Server authentication" and I'm not able to add "Client authentication". Does selfssl.exe not support client authentication?
When SQLserver2K was installed it placed master, model, msdb, tempdb data files in the installation location (i.e. C:Program Files....). This puts pressure on the C: drive, which also holds the page/swapfile. I want to move at least the tempdb location to the new 'Default data directory' and log directory we set after installation (i.e. E:MSSQLData).
How do I get tempdb to relocate to E: given that it gets recreated each time SQLserver starts?
I am interested to hear if people think it would be a good idea to movethe Master & TempDB to a different HD.Here is my DB Server's set up:1. Processor: (1) AMD XP 28002. 1st HD (IDE 0) is the system & boot drive3. (3) SCSI HD make up a hardware RAID level 0 (striped withoutparity)solution - these striped drives are just for my working DBs4. (1) SCSI HD that's not doing anything.I want to put the Master & TempDB on the SCSI HD that's not doinganything. Would that be the best place for it for maximum performance orshould I put in the striped array. I am leaning more towards putting onthe SCSI HD that's not doing anything. What do you all think?Ed*** Sent via Developersdex http://www.developersdex.com ***Don't just participate in USENET...get rewarded for it!
We had an issue last night where tempdb ran out of space on one of our servers. Upon investigation I found that SSMS was reporting only one data file assigned to tempdb. I knew this couldn't be the case and dove into the system tables to figure out what is going on. I found what appears to be data corruption. There are a number of file records that appear in the master.sys.master_database_files that do not appear in the sys.database_files table in tempdb.
I tried to add files that it showed already existed and they of course errored out. I restarted SQL Server to get tempdb rebuilt and that did not work either.
Has anyone else ever ran into this? What was the resolution?
Here are some queries to demonstrate what I am seeing. Terrible formatting I know, but I don't know of a better way.

I€™ve had a SQL 2000 server restored (using Veritas 9.1) to another server also running SQL 2000. I now have a collation problem.
When trying to add users to a database, I receive a "Error 446: Cannot resolve collation conflict for equal to operation" message.
I noted that tempdb and user tables collation don€™t match - so I was going to change the user tables. However, the master collation doesnt match tempdb, model or msdb.
Server is set to SQL_Latin1_General_CP1_CI_AS Master - SQL_Latin1_General_CP1_CI_AS tempdb, model, msdb - Latin1_General_CI_AS
I was under the impression that when tempdb was recreated it inherited the master database's collation? This doesn€™t seem to be happening.
Since,You cannot mirror the master, msdb, tempdb, or model databases.What will happen if i create new login,change existing security profile and new jobs,change of existing job on princicpal db. how these will be mirrored to other server and in case failover, how it will treat.
I have been tasked with encrypting an entire database, and I need some assistance. Everything that I have looked at leads me to believe that the only way to encrypt a whole database is to encrypt each column seperatly. I am completely stumped and could really use some help. Is it possible to encrypt a whole database? if so, how? If not, what other options do I have? Thanks in advance for the help.
How can I encrypt / decrypt whole database (data, objects ... everything) in SQL Server 2005 Express Edition? Quick solution from any champion of Databases would be highly entertained.
It is possible that Data Collection can cause massive increasing MB/sec to tempdb ? I cannot find connection with tempdb and I set cash file, but on same disk.
Or it can be something different? Last two weeks what I checked was Read/Write MB/s to tempdb increasing progressively.
One time it was about 20MB/sec
After it was reseting and again 1MB/sec..
What I checked , External company which install SQL Server made one file for tempdb, next week or during breaktime(it will be possible), I would like make 8files next weekend work.
Now I saw that TempDB mdf was still increased, but using was just 8-10%
Error:- (1 row(s) affected) DBCC execution completed. If DBCC printed error messages, contact your system administrator. Msg 5042, Level 16, State 1, Line 1
The file 'tempdev1' cannot be removed because it is not empty.
Note: =>I restarted SQLServer from SSMS and then ran same commands mentioned above ,......and getting same error... => I executed above commands and restarted services...no change...
I'm having an argument with our infrastructure architect who has just gone and bought lots of SSD drives to use for our tempdb data and log files, sounds great doesn't it? There is a catch though, his plan is to add the disks to the two available slots in each blade in a RAID0+1 configuration, effectively giving you one usable drive, and adding both data and log files on to one disk.
I then pointed out that SQL Server best practice is to host tempdb data and log files on two separate drive to reduce contention. The architect then basically said that because this isn't spinning disk the issue of drive, r/w contention isn't an issue I don't agree with this and wanted to get some opinions from the community, I'm still advising that two separate disks should be used but someone just went and spent £80k ($150k) on SSDs and doesn't want to back down...
I can get a snapshot of tables in tempDB, but I would like to track which procs are causing the load in the tempDB.
I think I can sample and record objects in the tempdb, but I would like to record the proc creating the most tempDB usage, and disk read/writes associated with those procs.
The DMV's give usage in the individual DB's, but what's a good way to correlate procs in the DB's to tempdb usage?
In an instance with 2008R2, the value of Transactions/sec in Master DB is very bigger than an instance with 2012. Is it normal? I ask it because both instances execute the same application with the normals differences between them (the Transactions/sec's number for the application's bds is similar).
I have a server which is not running optimally and I checked the default trace. I have around 600 entries in the default trace which are all Missing Column Statistics and the database is tempdb.is_auto_create_stats_on and is_auto_update_stats_on are both 1 for tempdb.
So we have new servers that are going to be installed with SQL 2012 and I'm debating the wisdom of splitting tempdb with multiple files.
I know it's a myth that performance automatically improves if you split it into a number of files based on processors, but I'm debating the wisdom of putting a file on each of my data / log file drives.
For instance, I have a server with a C: drive (OS), D: drive (Data for system DBs and install of programs - 458 GB), an F: drive for user DB data files (767 GB), and a J: drive for log files (255 GB).
Obviously no files are going on C:. I'm debating on whether or not we should even leave system DBs on the D: drive given in our current 2k8 servers, we end up with Memory.dmp files over flowing the D: drives as well as .cabs and other install / update files that tend to collect on that drive over the years.
But if we leave the system DBs on D:, I'm wondering if adding a second tempdb file to F: and a third to J: will improve query performance or not.
I have this situation: -Two nodes cluster with two instances sql cluster 2012 and I need to move all on the new cluster 2012 with finally the same virtually name and instances.
It's possible to restore master order to preserve all security?
I have a tempdb split into 4 files (5 if you include the log).
Autogrowth is disabled on the mdf/ndf files so that they can be used round robin (1 file per logical CPU).
Is there a way to be alerted when there is x% of free space left?
I know hwo to check the free space via t-sql but want to be able to be alerted. I could run a sql job that reports the free space and send a database mail message if under x% but wondered if there was a built in (or better) method?
We are seeing very high Average Disk Queue Length numbers in one of our clusters (both nodes of the cluster are Virtual, but have their own dedicated virtual environments). Our main data drive also houses TempDB, which I would like to move.
Each node in the Active/Passive cluster are running Windows Server 2012 Standard 64bit and SQL Server 2012 Enterprise 64bit. There is a separate drive for Log files and data files.
The data files also have TempDB on them as previously mentioned. I am reading that you can set up a local disk on each node of the cluster, with the same drive letter and path and then move tempdb as you would with a stand alone SQL Server.
I am in the process of formulating recommendations with respect to the purchase of additional storage for our current SQL 2012 SharePoint (2013) instance. My recommendation is to purchase separate storage (i.e, 15k disks) for the TempDB and Tlogs respectively (two sets of raid 10 disks). Currently, this server is hosting several instances, including SP, using two arrays (one for database and the other for Tlogs).
I am attempting to find information/recommendations on how to go about projecting the amount of storage for each of these while factoring in for growth.
Additional Details:
how to best formulate a reasonable estimate. Our largest content database belongs to IT and is currently ~80GB. That said, this is currently an outlier. The remaining content databases are less than 10GB (most are less than 2-3 GB). However, SharePoint will be used for digital document imaging in addition to, eventually, replacing file shares as our primary document storage medium once we roll it out.
Our current tempDB is ~400MB, but the instance was recently started a few days ago, as we had to failover to our backup server for hardware maintenance. I do not have any historical data on TempDB growth at this time. Also, I don't know how useful this would be given we have not fully deployed yet.
