Size Of Log Life
Dec 3, 2007
I am using SQL 2005. I have one very big database. The size of the DB is 1500986.88 MB and space available is 149359.48 MB. There are log files in this DB. The size of my log files are growing so big. The currently allocated space of one log file is 799874.50 MB and available free space is 38281.67 MB (4%). And the currently allocated space of another log file is 1500 MB and available free space for this log file is -760092.83 MB (-50672%)
I am not sure how come available free space for the 2nd log file becomes –ve. What does it mean? If I shrink log file, will I get any extra space? If not, what is the solution?

My one VB Exe used to connect SQL 2000 using windows SQL Server Driver. But same exe is giving problem of SQL Connection Timed out error in SQL 2005 - SP1.
As this exe refers 5 tables from database and insert as well as update the data. Also client pc and server pc's ping test is around 30 to 40 ms.
Is there any way where we can increase timed out level at SQL 2005.
One more thing which i noticed in 2005. its really very heavy software. even my IBM Xeon_346 server 3GB Dual CPU, 3 GB RAM also not able to handle.
Thanks in Advance

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?

Hi. I have a table called "Maxes" with three fields: Exercise_ID, weight, and date. This is for journaling my weightlifting progress. What I want my query to do is this:
Return just one record for each Exercise_ID, and only the one with the most recent date.
I tried this:
Code:
SELECT DISTINCT Maxes.Exercise_ID, Maxes.Date_Maxed, Maxes.[Max Weight]
FROM Maxes ORDER BY Maxes.Date_Maxed DESC;
but it doesn't quite work. Can someone show me how to do this?

I started receiving these alert messages, and after doing some re-search still can't figure out how to totally resolve it. From what I gather the value Microsoft stipulates 300 for PLE is not accurate if you running a 64 bit OS and dependent of the amount of RAM you allocate to SQL.
If I allocate 20 Gig of RAM to SQL, The PLE should not drop below 1500 - (PLE should be 300 for every 4 GB of RAM) (20/4)*300
During the course of the day it sometimes drops below 1500, so my question is how can I further see why and what query is causing this to happen???
I setup a monitoring job as mentioned by Steve Hood to capture results for me every 20 min.

STUCK! I have a consistent PLE value of 0. The server has 8GB RAM, I/O-CPU counters under 30%, various DMV's results show the buffer and memory cache do not calculate up to it's AWE (32-bit) allocation 7.5GB, waits don't show any problems, no locks, no blocks.
There are improvements to indexes that have to be made but where can I identify the root cause to the low PLE? The same process runs x6 quicker on 2 other much lower spec SQL servers exact copies from a data prospective, however there PLE is very high and not production.
Any ideas?

Page Life Expectancy (PLE) is pretty bad on my server. PLE is hovering around 3 minutes "sometimes" but is usally around 20-30 seconds.
Total memory allocated to SQL ( a fixed amount ) is set at 3GB.
Of the total memory allocated, SQL Server is using 2.52GB ... so there is room if needed.
The Buffer Cache is sitting at 2.09GB with a hit rate around 99.8%.
The Procedure Cache is sitting at 378MB with a hit rate around 90.5%.
CPU is hovering around 10-20%
Free System Page Table Entries is LOW ... at 22343
Disc Queue Lengths spike quite often to above 5 and sometimes as high as 36. Usually sitting at .05 to 1.0 (and there are times when the DQLs are great and not measureable.
What I need to find out is how to get PLE above the recommended 5 minute mark???
Please let me know if there are any other items I need to note.
Thanks!

I am trying to create a query that will show how much revenue that we have recieved from a customer After the first invoice and I'm having a difficult time creating a query to do it.. I have a customer table and a sales table joined by custno.
SELECT Customer.LastName, Sales.InvDate, Sales.AmtChargeFROM Customer INNER JOIN Sales ON Customer.CustNo = Sales.CustNo
The output I'd like is
CustNo, LastName, FirstInvoiceAmount, LifeCycleAmount
Getting the first inv date seems straight forward
SELECT Customer.CustNo, MIN(Sales.InvDate) AS FirstInv FROM Customer INNER JOIN Sales ON Customer.CustNo = Sales.CustNo GROUP BY Customer.CustNo
However getting the amount of that first inv and then getting the sum of all invoices not including the first invoice has me scratching my head.
Can anyone point me in the right direction?

Hello,
This is my first foray into SQL Server and i am coming from an Oracle background.
We are currently looking to upgrade a COTS package from a third party supplier. I would like to know is there any end of life announcement for SQL Server 2000 ? Is there an End of Support date announced for SQL Server 2000 ?
In Oracle there is a product life cycle announcement screen, I would like to know if there is a similar page in SQL SERVER and where ?
thanks

I have few servers that are VM and different version of SQL Severs (2008 Express/Standard, 2012, or 2014 Enterprise) and seems all of them have same issue that when I am querying "sys.dm_os_performance_counters" for "[object_name] LIKE '%Buffer Manager%' AND [counter_name] = 'Page life expectancy'" I am getting very big number (Ex, above 100K or some servers 1M).Is this number seems fine or acceptable?Â

I'm getting an alert which states that both my Buffer Cache Hit Ratio and PLE are low on one of my SQL Servers though I'm not sure how to correctly check this.
I ran:
SELECT object_name, counter_name, cntr_value
FROM sys.dm_os_performance_counters
WHERE [object_name] LIKE '%Buffer Manager%'
AND [counter_name] = 'Buffer cache hit ratio'
Which gives me the Buffer Cache Hit Ratio, cntr_Value of 9 though its constantly dipping between 3-3000 and is never steady and I'm unsure if this is normal.
I also ran:
SELECT object_name, counter_name, cntr_value
FROM sys.dm_os_performance_counters
WHERE [object_name] LIKE '%Buffer Manager%'
AND [counter_name] = 'Page life expectancy'
Which gives me the Page life expectancy of 209061.
If these values would cause concern and if this is a normal Buffer Cache Hit Ratio? It's constantly dropping from high or low from what I can see. These scripts were pulled from another forum and I'm assuming they're showing the correct values.

Our server administrator forwarded some messages from SCOM that indicate:
SQL DB Engine 2012 Page Life Expectancy and Buffer Cache Hit Ratio is too low
When I logged into the offending server, I could not find anything in the SQL Log File that indicates this.
I was wondering how did SCOM identify this issue - where in SQL Server would this have been reported to SCOM?

I am out of brain cells. I can not figure out how to upgrade instances of sql express to sql 2005 or even add an instance of sql 2005. I have installed/upgraded everything else (SSMS, etc.) to SQL 2005.
I am dazed and confused. I don't even know where to start in explaining what I have tried and done. I have 303 log files going back to 3/27/2007 from various attempts.
Where do I start in figuring this debacle out???

Hi 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... And the SPROC:------------------------------------------------------------------------------------------------------------------set ANSI_NULLS ONset QUOTED_IDENTIFIER ONGOALTER PROCEDURE [dbo].[retrieveData] @id int, @title varchar(50) OUTPUT, @creator varchar(50) OUTPUT, @assignee varchar(50) OUTPUT, @contact varchar(50) OUTPUT, @deliveryCost numeric(18,2) OUTPUT, @totalCost numeric(18,2) OUTPUT, @status tinyint OUTPUT, @project smallint OUTPUT, @supplier smallint OUTPUT, @creationDateTime datetime OUTPUT, @amendedDateTime datetime OUTPUT, @locked bit OUTPUT AS /**SET NOCOUNT ON; **/ SELECT [title] AS [@title], [datetime] AS [@creationDateTime], [creator] AS [@creator], [assignee] as [@assignee], [supplier] as [@supplier], [contact] AS [@contact], [delivery_cost] AS [@deliveryCost], [total_cost] AS [@totalCost], [amended_timestamp] AS [@amendedDateTime], [locked] AS [@locked] FROM purchase_orders WHERE [id] = @id; ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ The id being passed in is definately not null, and is set to a value of an item I know exists. The resulting error is:
Exception Details: System.InvalidOperationException: String[1]: the Size property has an invalid size of 0.Line 63: retrievePODetails.Connection.Open();Line 64: retrievePODetails.ExecuteNonQuery();[InvalidOperationException: String[1]: the Size property has an invalid size of 0.] System.Data.SqlClient.SqlParameter.Validate(Int32 index) +717091... ...

Using 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

I want to know encrypted data's size for designing database field size.
For example, cardnumber varchar(20) Encrypted by Triple_DES and PassPhrase, How match size does need to encrypted data store field.
I think the size does not depend to PassPhrase char length.

Just wanted to know what is a general rule of thumb when determining log file space against a database's data file.We allow our data file for our database to grow 10%, unlimited. We do not allow our log file to autogrow due to a specific and poorly written process (which we are in a three month process of remove) that can balloon the log file size.Should it be 10% of the Data file, i.e. if the Date file size is 800MB the log file should be 8MB?I realize there are a myraid of factors that go against file size but a general starting point would be nice.ThanksJeff--Message posted via http://www.sqlmonster.com

Hi,
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

Hi,
i use this script that show me the size of each table and do the sum of all the table size.
SELECT
X.[name],
REPLACE(CONVERT(varchar, CONVERT(money, X.[rows]), 1), '.00', '') AS [rows],
REPLACE(CONVERT(varchar, CONVERT(money, X.[reserved]), 1), '.00', '') AS [reserved],
REPLACE(CONVERT(varchar, CONVERT(money, X.[data]), 1), '.00', '') AS [data],
REPLACE(CONVERT(varchar, CONVERT(money, X.[index_size]), 1), '.00', '') AS [index_size],
REPLACE(CONVERT(varchar, CONVERT(money, X.[unused]), 1), '.00', '') AS [unused]
FROM
(SELECT
CAST(object_name(id) AS varchar(50)) AS [name],
SUM(CASE WHEN indid < 2 THEN CONVERT(bigint, [rows]) END) AS [rows],
SUM(CONVERT(bigint, reserved)) * 8 AS reserved,
SUM(CONVERT(bigint, dpages)) * 8 AS data,
SUM(CONVERT(bigint, used) - CONVERT(bigint, dpages)) * 8 AS index_size,
SUM(CONVERT(bigint, reserved) - CONVERT(bigint, used)) * 8 AS unused
FROM sysindexes WITH (NOLOCK)
WHERE sysindexes.indid IN (0, 1, 255)
AND sysindexes.id > 100
AND object_name(sysindexes.id) <> 'dtproperties'
GROUP BY sysindexes.id WITH ROLLUP) AS X
ORDER BY X.[name]
the problem is that the sum of all tables is not the same size when i make a full database backup.
example of this is when i run this query against my database i see a sum of 111,899 KB that they are 111MB,but when
i do full backup to that database the size of this full backup is 1.5GB,why is that and where this size come from?

Here are my scenarios:
We have an application with replicated environment setup on sql server 2012 . Users will have a replica on their machines and they will replicate to the master database. It has 3 subscriptions subscribed to the publications on the master db.
1) We set up a replica(which uses sql server 2012) on a machine with no sql server on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 33gigs and ldf has grown to 41 gigs. I went to sql server management studion . Right click and checked the properties of the local database. over all size is around 84 gb with little empty free space available.
2) We set up a replica(which uses sql server 2012) on a machine with sql server 2008 on it. After the initial synchronization(used replmerge tool) the mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
3) We set up a replica(which uses sql server 2012) on a machine with sql server 2012 on it. We have dropped the local database and recreated the local db and did the initial synchronization using replmerge tool. The mdf file has grown to 49 gigs and ldf has grown to 41 gigs. I went to sql server management studio , Right click and checked the properties of the local database. over all size is around 90 gb with 16 gb free space available.
Why it is allocating the space differently? This is effecting our initial replica set up times.
