SQL Server 2008 :: Virtual Server Disk Configuration?
Mar 14, 2011
I have been tasked with moving our SQL server estate onto new 64bit SQL 2008 Virtual servers on a VM base. Each Virtual server will be attached to our SAN that i will have no control over. Do i ask for multiple LUNs pretending that there is a COS), Etemp), FData) and Glog) disk structure or do I just present a very big space as a single C: drive and let it go.We are consolidating lots of old physical servers onto fewer (more powerful) virtual servers (according to the VM and SAN administrators)
Hello - does anyone have experience w/SQL Server 2005 in a virtual environment? I'm considering this for a production environment but not sure if performance will suffer. Our databases will have a lot of writing but not too much reading. A SSRS solution is currently the only app. connecting to the SQL db. Max users to server at any given time will be very low (~10 users max). But the databases are pulling in data from other, outside multiple data sources on a daily basis.
I have a question concerning where to put certain database files for the followinig RAID configurations. The server has 2 RAID configs: 2 hds in a RAID 1 and 4 hds in a RAID 10. The server will host 4 database instances: A replicated db, a Reporting Services db (which technically constitutes 2 db instances) and an application db. In order to get the best performance, should I put the OS, SQL binary and log files on the RAID 1 config with the data and tempdb on the RAID 10? If not, please explain the best solution. Thank you!
Any good starting point to understand for a specific db, how many max VLFs are good to have so that it does not cause long startup or backup times?
Also, I need some calculation so that I can identify a best growth parameter I will setup for each database ?
I'm seeing the below msg in errorlog and curious to know the changes (right sizing/growth) to be done? As of now 100 MB of log file growth value is set (refer: [URL] ....)
Database BizTalkMsgBoxDb has more than 1000 virtual log files which is excessive. Too many virtual log files can cause long startup and backup times. Consider shrinking the log and using a different growth increment to reduce the number of virtual log files.
I have got problems with installation of a default instance on SQL Server 2008 on Vista Home Premium. During the step of Server Configuration you should enter UserName and password for each service. I do not know what user name to type. I tried every possible combination but the outcome is always the same - after typing usernames and passwords, installation suddenly fails without casting any exception. I'm not sure if I do something wrong (wrong User Name or Password) or is it a problem with installation application or with OS. Please, help.
This is SQL Server 2008R2. On the SQL Server Configuration I'm unable to see SQL Server Browser. But when I check the services I can see the SQL Browser running.
Under SQL Server Configuration Manager > SQL Server Services
1. Full text 2. SQL Server (Default) 3. SQL Agent (Default)
But I'm unable to see the SQL Browser services here. What is the remedy?
I'm having trouble in configuring Yahoo's SMTP for Database Mail. Here is my current settings:
Email Address: xxx@yahoo.com Server Name: smtp.mail.yahoo.com Port Number: 465 This server requires a secure connection (SSL) - check Basic Authentication Username: xxx@yahoo.com Password: xxx
When I tried sending a test email, it didn't work. But when I changed my SMTP to use Gmail, it worked!
Hi, I have a problem with SQL Server 2005 Reporting Service. I installed Reporting Service in my machine. When I was trying to configure the Reporting Service, Report Manager Virtual Directory got disabled. I need to enable this Report Manager Virtual directory. I can see the disabled link for Report Manager Virtual Directory and it shows the error: Report Manager Virtual Directory is not configurable for the current mode. Kindly help me out of this problem. Thanks Subhendu

Hi, I hope someone can help me! I changed the TCP port that the default instance of SQL 2005 x64 SP1 is listening on and now SQL server won't start as the port is being used - no problem I say to myself, I'll just change it again, however I can't!
My problem is that I can not change the TCP Port back again using Configuration Manager - no matter what values I put in, after a restart of the instance it comes up with this in the IP Addresses tab for TCP/IP Properties and SQL Server won't start:
IP1 Active Yes Enabled No IP Address aaa.bbb.ccc.111 TCP Dynamic Ports TCP Port 0
IP2 Active Yes Enabled No IP Address aaa.bbb.ccc.222 TCP Dynamic Ports TCP Port 0
IP3 Active Yes Enabled No IP Address aaa.bbb.ccc.333 TCP Dynamic Ports TCP Port 0
IP4 Active Yes Enabled No IP Address 10.1.1.1 TCP Dynamic Ports TCP Port 0
IP5 Active Yes Enabled No IP Address 127.0.0.1 TCP Dynamic Ports TCP Port 0
IPALL TCP Dynamic Ports 2020 TCP Port 2020
Interestingly, the ip address that the server is listening on aaa.bbb.ccc.444 is not reported in the list of IP addresses in the configuration manager for this instance, yet it is when I view the available IP addresses for the other two instances - is this significant?
I have tried failing to the other node, changing it there, changing it at the console and also while logged onto the the virtual machine remote desktop, rebooting both nodes, etc, etc. There are two other instances on this cluster that are still working fine but I hvae not attempted to change the TCP ports they listen on.
I used the same method to change this default instance as I did for a named instance on a similarly configured cluster and it worked fine. How to fix this?

Please excuse the following question from a newbie to SQL.
I have been asked by our DBA to set-up a new SAN tray to cope with our company data bases.
We have an MSA1000 fibre channel that the Database Servers connect to via a Fibre link.
We have a second SAN tray attached that currently has no disks attached to it, this is the one that we are going to use for the new Database set-up.
We will be purchasing 300 GB 15k disks but the question i have is how many disks and what configuration will i need for the following scenario.
100 GB PRIMARY DATA 50 GB DATABASE LOG 100 GB SECONDARY DATA 300 GB ARCHIVE DATA 50 GB TEMP DATABASE
I have been reading as much as i can about SQL and Disk I/O and it appears on the face of it that Raid 10 would be the fastest (and most fault tolerant) for the this set-up.
If anybody has any ideas they would be gratefully received.
We are going to implement either a replicated database or use log shipping to another database to support our reporting needs. Basically we are moving reporting over data off our transactional database.
With this in mind, I have several questions: Are there any special configurations in terms of disks for a database in this situation?What are the recommended raid types? Also, we currently store our data in one filegroup and indexes in another so obviously I'll want those on 2 separate physical disks other than the C:. What about the log files? Do I care where they go (on C: or another physical drive separate from C:, data filegroup drive and index filegroup drive)?
I have a three tier system using SQL server 2000, we are currently experiencing IO bottle necks on our SCSI Raid 10 array, which holds the Data and the logs in separate partitions.
So my options as I understand it are:
Get Enterprise edition
or
Get another physical raid 10 array and separate the logs and data i.e. data on one array and logs on the other array.
I would like to try the latter but I am totally unsure how much difference this will make or whether it will make any difference at all.
Does anyone know how much performance increase I will get from using two arrays as opposed to one?
Any other advice on this scenario would be greatly appreciated.
I have just finished installing SQL 2005 Ent Edition on Win 2000 Adv Server, SQL2005 SP2, and SP2 Hotfix KB934458. After the installation, I could see and configure all services via SQL Configuration Manager and SQL Server Surface Area Configuration tools. This worked for a couple of days and now both configuration tools no longer detect SQL2005 components. SQL Server Surface Area Configuration issued an error that said "No SQL Server 2005 components were found on specified computer. Either no components are installed, or you are not an administrator on this computer. (SQLAC)". SQL Configuration Manager did not list any installed services. I don€™t know what caused this. Anyone has any idea? Please help! Below is the Installation Report which shows installed components.

The following components are installed on this server
What is a virtual server?In my new job,my boss mentioned about moving the websites from a physical server to a virtual server.Why is this done or needed? Also he insists that I buy and install SQL server 2000 enterprise edition in my laptop and use the enterprise manager to access their server.Can't I just download the client tools from their SQL package and be able to access their server?Do I need a CAL or is it just enough to have a permission in their network for my laptop?
I am testing out server virtualization for our company and I hit a road block when I got to SQL Server. All the test consists of is installing IIS 6 on 2K3 Standard, installing SQL Server and trying to connect to the database in a SqlDataSource in Visual Web Developer 2008. I can access the Default.aspx page at http://server/Default.aspx, but I cannot access the database. TCP and Pipes are on and I shut down the Windows Firewall on both the host and guest OS's.
I can't connect to SQL through code locally or remotely. I can't connect with Server Management Studio from a remote machine (Error: 1326 - could not open a connection), I cannot connect from the host OS, but I can connect locally within the VM to Management Studio.
I really need some help. This is what I'm trying to do: first of all, i have a PC running Vista. Now on that PC, i have a virtual machine using VMWare Workstation 6, which has Win XP with SP2 installed on it. On the virtual machine, i have Visual Studio 2005 and SQL Server 2005 Express Edition with SP2; now, the thing is, i have a program in C#, which is supposed to connect to a network, but since I'm running on just one PC which is not connected to a network, i instead connect to 127.0.0.1 via port 1433. Now here's where my problems start. At first, i could not connect because i kept receiving an error which said "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provedier: TCP provider, error: 0 - No connection could be made because the target machine actively refused it.)". A friend of my mine helped, so i did the following: i went into SQL Server Surface Area Configuration (configuration for localhost) , changed the remote connections to allow for both local and remote, using both TCP/IP and named pipes, restarted the database engine, started the SQL Server Browser; then i went to administrator tools, Data Sources (ODBC), and from System DSN tried to add an SQL Server. I gave it a name, and on the server textbox i tried typing "localhost", but doing so, i could not get past the next screen, (i did specify the port as 1433) where i have to chose between win nt and sql server authentication, and neither would work (even though i know the sa password and can log on to SQL Management Studio using that password). Then i tried copying the server name from the management studio, as the server when trying to add the system DSN. That seems to have worked, and i finished ading the SQL Server to the System DSN, using the database which i wanted. But after all these steps, i still get the exact same error as before - "An error has occurred while establishing a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections. (provedier: TCP provider, error: 0 - No connection could be made because the target machine actively refused it.)".If someone can please help - i've tried everything i can think of - i can access the internet from the virtual machine, i even tried disabling the firewall, but no luck. Is it because of the virtual machine? If so, can anyone suggest a solution? I actually doubt it, because i've even tried to install it on my pc, not the virtual machine, so on vista - and also installed SP1 for VS 2005 and SP1 for Vista, but still the same thing. Sorry for making this post so long, but if anyone can help, i'd really appreciate it. Thanks!
I am looking for some first-hand experiences from fellow DBA's where they had SQL Server running on a Win2K3 VM. What sort of issues (or successes) did you find re: resource sharing, swap files, etc? Are there any experiences where using a VM negatively affected your environment?
I have two instances of SQL Server running on my Development machine.I am having some performance problems and while investigating theproblem I saw with the Process Explorer form Sysinternals that bothinstances consume each 800 Mbytes of memory!I experimented with sp_configure and by giving both instances a fixedmemory size. Both methods do not seem to have any effect.Can anybody explain me why SQL Server is using so much memory?Thanks for any information.Evert WiesenekkerPSBesides the northwind database I only have one simple extra database(70 Mb in size) installed.
I have a 2 part question about adding a new 'named' Virtual Server to an existing Clustered SQL Server 2000 install.
I have a 2 node MSCS Cluster (WIN2K advanced Server sp4) with a default SQL Server instance. This has been in production and working fine. I created a new Cluster resource and reran SQL Server 2000 ENT setup and added a second Virtual SQL Server (named instance). After many problems, finally got the second Server installed. Now I have 2 SQL Server instances in the Cluster - from what I understand, you can have up to 16, each seperate installs with seperate Cluster resources. Thus the problem:
For the Second Instance, I have specific instructions from the Applications vendor on how to install SQL Server to work with their APP. I need install SQL Server WITHOUT the Full Text Search component and WITH a specific Server Collation (Binary order for use with the 850 Multilingual character set). (I have done this same setup on standalone SQL Server installations for this APP and they have gone smooth).
When I installed the new Virtual 'named' instance in my Cluster, I Could NOT 'DESELECT' Full Text Search when I choose Custom install.. it does not appear as an option???
Also, I chose the "Binary order for use with the 850 Multilingual character set" during the installation, but that is not the Server Collation that is installed...
I have already installed SP3 for SQL Server against the Virtual Server on this Cluster, as well as a HotFix... and Now I'm thinking I need to rerun the SQL Server installation, uninstall the second server and reinstall to see if I can fix the 'Collation problem' .. but I'm not sure if this is the right course of action.
Does anyone know why I cannot 'deselect' Full text search component at install, and any ideas why it did not install with the SQL Server Collation that I specified at install????
Hi,We have a prod server running on SQL server 2000 64 bit. It is a4cpu server with 16GB of RAM. we have a maxmemory setting of 15.5GBfor sql server. Inspite of 15GB being available for sql server, itstill uses paging file space, a lot. When looking thru task maanger wecan see sql server using 15.5GB of Memory usage and 22GB of Virtualmemory usage. I don't understand why it should even be using closer to7GB of Paging space, when it has so much memory. How does SQl serveruse Virtual memeory vs Physical memory?HAs anyone seen this before.ThanksGG
Can I Install a default instance on Virtual SQL Server on a 2 node Cluster. If I already have a default instance on a different Virtual SQL Server on the same clustered Server.
What i am trying to do..
if i create 2 virtual sql Server (say sqlVi1 and sqlVi2).. i want o connect using sqlVi1 and sqlVi2..not Sqlvi1 and SQlvi2Namedinstance.
If yes..How can I do it?
Thanks in advance I Hope someone from Microsoft or MVPs will help me.
if this is not the corrcet forum...please point me the correct one
I have a clustered environment where I have virtual servers running and I have SQL 2005 on one of the virtual servers. Is there any way to have multiple SQL instances running on one virtual server, if so how? If this is not possible than what are some of my options? Thank you, Kern Probation
I am unable to successfully complete an install of Visual Studio 2005 with SQL Server 2005 Express on a Virtual PC 2004 image, which seems to be a pretty reasonable expectation. The installation completes successfully all of the way through in a Windows XP Pro SP2 image, but at the end the installation program informs you that SQL Server Express has failed to install, with no other explanation. No setup log files give any information as to why the installation failed. Then I see in the fine print for SQL Server Express downloads that "There is no support in this release for Virtual Server, Virtual PC". (http://download.microsoft.com/download/c/c/6/cc66b572-a402-4c6a-8233-b9c7d05840c7/RequirementsSQLEXP2005.htm)
We need to move a cluster to a new data center. There is a strong preference to retain the previous SQL Virtual Name. The existing cluster has a single default instance. We understand that when you have created a SQL Server FCI that you can change the SQL Virtual Name but not the instance name. So if the current SQL Virtual Name is SQL1 then at a high level:
Build cluster at new DCInstall SQL Server FCI with a virtual name as SQLTEMP and as a the default instanceShutdown old cluster ???Rename SQLTEMP to SQL1 Since there is an existing SQL Virtual Name my concern is that we cannot simply rename SQLTEMP to SQL1. Do we need to delete the VCO from AD for SQL1 in step
I am trying to install SQL 2005 in a 2-node virtual Windows 2003 cluster. I set the cluster up through Virtual Server 2005 with 2 virtual nodes and one virtual domain. The nodes can connect to each other as well as the physical machine. When I try to install a fresh copy of SQL 2005 on my cluster, I get an error every time. The error stops the installation while checking system configuration after installing prerequisites. The log file entry is as follows:

Local SQL 6.5 SP4 on a Windows NT SP4 workstation (Pentium 350 / 128 MB). SQL server has 32 MB of RAM. It starts well but begins continuously eating up virtual memory by 16k blocks in a second, until it takes all virtual memory.
Server's shutdown generate following error in Event log System section:
Event ID: 7011 Source: Service Control Manager Description: Timeout (120000 milliseconds) waiting for transaction response
When I start Server from command prompt with -f switch, it did not eat virtual memory, and did not generate any error in Event log at shutdown.
