Estimating Database Size
Apr 22, 2008I 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

View 4 Replies View RelatedEstimating Memory Size/Config Requirements
Jun 4, 1999Is 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.
DB Size Not The Actual Physical Size
Feb 15, 2000Hi,
An MSSQL DB running SAP indicates a smaller DB size (MMC & SAP) than the actual physical size. The difference is about 8 GB.
A lot of records were deleted before this. Did they remain in the DB as NULL values or something ?
Does anyone know what the reason for this could be ? And how to clean this up ?
Thanks in advance,
Paul
Looking For Physical Design Suggestions...
Jul 20, 2005I got a server that has a RAID-5 array partitioned into C: and D:drives (OS Win2K Adv. Server installed on C:). The server also has amapping to a NAS device using the latest protocols that trick thesystem into thinking the map is actually a local SCSII drive. That'sdrive X:.This server is used only for SQL, and contains an OLTP database thatsees a lot of use and is pretty heavily indexed.I am toying with the idea of centralizing my data storage on the NAS(data center network segment is 1-gigabit ethernet). So I wasthinking about putting my primary data file on the NAS (drive X:) andkeeping all tables there, creating a secondary data file on localRAID-5 (drive D:) and putting all non-clustered indexes there, as wellas keeping the tempdb there and specifying the sort in tempdb option.Log files would also remain on D:.If anyone can suggest a better scenario given the above setup - I'dlove to hear it. Much appreciated.Alexey Aksyonenko

View 1 Replies View RelatedActual Physical File Size
Jun 21, 2004Hi Everybody,
I like to compute the actual physical database file size using queries.
From the EM database properties, the file size shown is not matching with the master..sysaltfiles.size
Ex. Actual file size is 12MB and 1MB for MDF & LDF respectively.
'sysaltfiles' shows 1464 & 96 resp. Since they are shoing it as 8K Pages,
96*8 = 768KB is not matching with 1024KB for the LDF file.
Is there any overheads (additional space from the physical file for file headers) allocated?
Thanks

SPROC Problem - String[1]: The Size Property Has An Invalid Size Of 0.
Mar 16, 2007Hi folks,Can anyone enlighten me here? I'm trying to use a SPROC which, when supplied with an int, looks up the table and returns certain columns from it. I'm using a SqlCommand, here's my codebehind: ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ SqlCommand dataSource = new SqlCommand("retrieveData", new SqlConnection(dbConnString)); dataSource .CommandType = CommandType.StoredProcedure; dataSource .Parameters.AddWithValue("id", poid); dataSource .Parameters.AddWithValue("title", title).Direction = ParameterDirection.Output; dataSource .Parameters.AddWithValue("creator", creator).Direction = ParameterDirection.Output; dataSource .Parameters.AddWithValue("assignee", assignee).Direction = ParameterDirection.Output; etc, etc...

Error - Output Param - SP - Size Property Has An Invalid Size Of 0
Nov 14, 2007Using C#, SQL Server 2005, ASP.NET 2, in a web app, I've tried removing the size from parameters of type NCHAR, NVARCHAR, and VARCHAR. I'd rather just send a string and let the size of the parameter in the SP truncate any extra chars if need be. I began getting the error below, and eventually realized it happened only with output parameters, as in the code snippet below.String[3]: the Size property has an invalid size of 0. par = new SqlParameter("@BusinessEntity", SqlDbType.NVarChar); par.Direction = ParameterDirection.Output; cmd.Parameters.Add(par); cmd.ExecuteNonQuery();What's the logic behind this? Is there any way around it other than either finding out what the size should be, or assigning a size larger than would ever be needed? ThanksMike Thomas

Combining Physical Files
Feb 28, 2001Can anyone inform me how I would go about merging or combining 2 or more physical database files into 1. For example, suppose you have the following files out on your server:
c:mssql7datapubs_data1.mdf
c:mssql7datapubs_data2.ndf
c:mssql7datapubs_data3.ndf
but you only want
c:mssql7datapubs_data1.mdf
Is there any way to combine pubs_data2.ndf and pubs_data3.ndf into pubs_data1.mdf so you are only left with 1 database file called pubs_data1.mdf?
Thank you,
PJ

Bit Datatypes Physical Storage
Feb 15, 2005Can anyone explain to me how a column defined with a "bit null" datatype is physically stored in MSSQL? Is it stored like a "tinyint null" physically? In other words, how many bytes on the row on the page does a "bit null" datatype consume (assuming a non-null value 0, or 1 is the current value).
Is there any good documentation about the physical storage layout for a data page?

Physical RAM Stress Test
Nov 20, 2006Hi,
I have a new server where 32GB of RAM is installed and I have user databases on this server.I am using SQL server 2000 Enterprise edition and Platform is Windows 2003 adv server, which supports upto 128GB of memory.
sp_configure 'awe enabled' is set to 1 and at OS level, AWE is enabled as well.
max server memory (MB) is 2147483647
I was doing some stress test on this server but memory usage doesn't go beyond 180MB....can someone suggest a test for physical RAM ?
How can I make sure that application will make full use of available physical memory?

and we will install new (2) two server for High Availability with VMware vSphere (ESXi) 6.0
and we will have (2) two Virtual Machine :
1st VM :
OS : Windows Server 2012 R2

Migration To Another Physical Location
Apr 4, 2008I may be put on a project involving the migration of a SQL Server 2000 database from one physical location to another. I've never done something like this so any guidance would be appreciated.
My plan is to:
1. Backup the live database.
2. Do a restoration at the new location.
3. Set up transactional replication between the two databases.
4. Update records to point to the new db.
Are there any problems with doing it this way? Is there a better solution? I am trying to do this without any downtime, or as little as possible.
Thanks for any help.
