Is there a way to see how much memory your current SQL Server install is using? I recently had to do some reconfiguring, and although it went fine, I'd like to build a spreadsheet model so I could see what different parameter values do to memory usage. I'm kinda surprised there isn't one already.
And yes, I realize that 99% of the configuration options go away in 7.0. We're going to have 6.5 here for a while yet.
Is there any good online documentation describing rules of thumb for estimating and planning a SQL Server 2005 deployment in support of a Windows rich client/WCF services architecture?
TIA,
Ian
I have a virtual server (VMware ESX) with 64GB RAM running a single instance of SQL 2012 SP1. The max memory config is set to 59392 (58GB).
The Page Life Expectancy for this server has been averaging well under 10 mins for the last few days, according to our monitoring.
I have been checking the amount of data in the buffer cache periodically during the day with the below query, which seems to show that there is never more than about 10GB of data at any one time, frequently dropping below 5GB:
SELECT COUNT(*) AS BufferPages,
CONVERT(decimal(10, 2), COUNT(*) / 128.0) AS BufferMB
FROM sys.dm_os_buffer_descriptorsWhy would the amount of cached data be so low (and cause so much churn)?
I am aware that other things will require some of that memory (plan cache etc.) but with Max Mem of 58GB, I would expect there to be a much higher amount of actual cached data at any one time. I did the same checks on another VM with the same amount of RAM/Max Mem setting, and there was 50GB of data in the cache, with PLE measured in hours.
I would like to know how to estimate the size of a database before filling it with records. I need a sample calculation. I am new to this concept.
Pls help.
I have created a table called EMP with three columns such as Empname varchar(50), Salary int, maritalstatus bit, bloodgroup char(10). Initially the table does not contain any rows. But i have been told that the table will contain 1 lac rows. So i have been asked to estimate the database size. I don't know how to estimate the database size without inserting the records. Pls help me how to do it?
Thanx

I'm developing a website that will be suported by a SQL Server database. The estimated number of records for that database will be around one million. I'm concerned with the possibility of my machine being unable to respond to the needs of such a database so i decided to acquire a new one. How do i calculate the hard disk and RAM i'm going to need for this database to function properly ? I know that i can make a HD prediction by adding the sizes of each field of my database and multiplying by one million but i don't know how much KBs each field occupy (some of them -few- will even be free text fields). And the RAM ?
Help... Anybody ?
Thanks,
Carlos.
We have a new server (4 dual-core CPUs and 8GB ram) with Windows 2003 x64 installed. We need to put SQL 2000 on the system and want to maximize it for sql performance (will be dedicate to SQL). Do we enable awe in SQL? Are there any 3GB switches we need to put in the boot.ini for the 32-bit subsystem? Should we use the 32bit version of Windows and just use awe and pae?
Thanks

Does anyone know if there is a rough guide in terms of how much memory SQL server will normally use relative to the size of the actual databases that it is hosting?
For example, I'm working on a server that hosts only about 250-300 MB worth of data (including all of the full text indexes, etc.) but the sqlservr.exe process is using 1.25 GB of ram. Also Page Reads/sec is around 1200 -- despite there being over 5 GB of RAM available and not being used (the PF is about 3.25 GB, total memory in the machine is 8GB). Below that w3wp.exe uses only 290 MB and lsass.exe uses only about 225 MB. The machine is a web/database server that is hosting ASP.NET 2, ASP.NET & Classic ASP pages (and the associated databases). For the amount of hardware, the server seems to be responding to requests on the slow side. While some of this is probably due to the legacy code-base, there seems to be a noticeable difference in speed after SQL Server is restarted.
Thanks,
Jeremy

Hi,
Anyone knows what the size should the Paging File be for a 8 P 16 Core Opteron server with 128GB memory installed? The server will be running SQL 05 Ent and IIS, on top of Win2k3 R2 x64 Ent.
Please also give the reason for that size.

In SQL Server 2014, how big for the block size is better for performance? 64 KB? 4 KB?
For normal database files, best practise is 64 KB disk block size. Not sure if it is same for memory-optimized filegroup.
Hi All
Is there anyway you can estimate the execution time/cost of a query prior to actually executing it?

I am trying to resize a database initial log file from 500M to 2M. I€™m using€?
ALTER DATABASE <DBNAME> MODIFY FILE ( NAME = <DBLOGFILENAME, SIZE = 2 ) "
And I'm getting "MODIFY FILE failed. Specified size is less than current size." I tried going into the database properties and setting the log file to 2M, but it doesn€™t keep the changes.
Any help with this process?
Currently have a single hard coded file path to the SSRS config file which parses the file and provides the reporting services web service url. Â My question is how would i run this same query against 100s of servers that may or may not share the same file path as the one hard coded ?
Is there a way to query the registry to find the location of the config file of any server ? which could be on D, E, F, H, etc.Â
I know I can string together the address followed by "reports" and named instance if needed, but some instances may not have used the default virtual directory name (Reports).
Am I going about this the hard way ? Is there a location where the web service url exists in a table ? I could not locate anything in the Reporting service database. Basically need to inventory all of my reporting services url's.

I've been researching AWE to determine if we should enable this for our environment.
Currently we have a quad core box with 4 gb of RAM (VMware). OS: Windows 2003 std, SQL Server 2005 std. 3GB is not set but will be as soon as we can perform maintenance on the server.
I have read mixed feedback on AWE, either it works great or grinds you to a hault. I would assume that the grinding to a hault is due to not setting the min/max values correctly or not enabling the lock page in memory setting.
We only have one instance of SQL on the server and this box won't be used for anything else aside from hosting SQL services. We do plan on running SSRS off of this server as well.
1. Will running SSRS and enabling AWE cause me problems? Will I have to reduce the max setting by the SSRS memory usage or will it share and play nice?
2. How do I go about setting the Max value? Should it be less than the physical RAM in the box? Right now its set to the default of 214748364, even if I don't enable AWE should this default value be changed?
3. It seems that even at idle the SQL server holds a lot of memory and the page file grows. If I restart the process in the morning, memory usage in taskmon is at 600mb or so. By the end of the day, its up around 2gb. How can I track down whats causing this, should this even concern me?
4. The lock Page in memory setting worries me. Everything I've read on this seems to give a warning about serious OS and other program support degradation. In some cases to the point where they have to restore the settings on the server before they can bring it back up. What are your thoughts on this.
For SQL 2000, what are the licensing requirements for a clustered environment? I thought you needed datacenter for the OS, is there a clustered version of sql server, or do you need 2 copies of enterprise edition. Also, if you cluster can you license sql cals for clients, or do you have to do by processor?
View 4 Replies View RelatedI have a sql server (2k sp4), a web server and a development machine.
I need to install sql server reporting services and am confused as to the prerequisites and as to what gets installed where.
Is there a server install and a client install or do I run the same install on both (and deselect what's not required on each).
Sorry it's a bit vague but in my research various people have told me various different things.
Hey all,
I couldn't find an answer anywhere on the site, if there is one, could you please let me know where to go? Thanks.
Here goes. We receive large csv files, around a million records a month. What we need to do is:
- Of course, import these records
- Be able to run failry heavy reports on around 3 months worth of data (about 3 million records)
- Wanting to store at least a years worth of data
What I need to know:
- What server(s) spec (CPU, HDD, memory, etc) would we need to import and run reports quite fast. Don't want the reports/imports to take days to run. The reports will need to be run by about 3-5 people at the same time
- What OS and database type should I use (I was looking at Windows/Linux and MS SQL/MySQL)
- If we run these types of reports, can we use the same SQL server to run/store other applications (eg. CRM, etc) with no real impact on performance. There would be at least 20 people using the CRM database at the same time.
Thanks
Can 2005 be installed on XP Media Center Edition? I looked on the SQL site,

What are the minimum requirements for setting up replication ?
i mean, the connection requirements, bandwidth requirements, minimum hardware and software requirements ?
Is it possible to setup a replication across the internet ?
I have seen it mentioned that, unlike with the MSDE where DTS runtime was covered, the new SSIS is not covered by the SQL Server 2005 Express.
Does anybody know of an official microsoft web page detailing comprehensively what is required.
As far as I can gather the client will need a full version of SQL Server 2005, enabling the installation of the client tools, which as far as I can tell are required for the running of the SSIS.
This statement could be totally wrong but clear information seems hard to come by and seems mainly hearsay.
Thanks
