SQL 2012 :: Configuring Memory Per Query Option And Index Create Memory Option

Feb 10, 2015

So I started a new job recently and have noticed a few strange configurations. Typically I would never mess with min memory per query option and index create memory option configuration because i just haven't seen any need to. My typical thought is that if it isn't broke... They have been modified on every single server in my environment.

From Books Online:
• This option is an advanced option and should be changed only by an experienced database administrator or certified SQL Server technician.
• The index create memory option is self-configuring and usually works without requiring adjustment. However, if you experience difficulties creating indexes, consider increasing the value of this option from its run value.

Configure Max Memory Option

May 23, 2002

Hello all,
I have a Production server which has 2gb of memory. SQL server memory is set to configure dynamically.
The Server also has a third party application on it. The third party application was running poorly, and the software vendors recommended running the following sql on a job every hour:-

exec sp_configue 'max server memory(MB)',500
reconfigure

exec sp_configure 'max server memory(MB)'1400
reconfigure


The hourly job has the effect of flushing out sql server memory every hour and setting the max amount down to 500mb and back up to 1400mb. SQL server still manages memory dynamically, so within the hour before the next time the job runs, sql server could use more than 1400mb.

I' feel that this job will degrade sql server performance because it will empty the buffer cache and procedure cache. My approach would be to select the 'use a fixed memory' option and set it to 1400mb, and not use their recommendation.
Does anybody have experience of this, and perhaps explain the consequence of running the recommended job every hour.
Any advice would be great.

Questions About Memory Based Bulk Copy Operation(InsertRow Count,array Insert Directly,set Memory Based Bulk Copy Option)

Feb 15, 2007

Hi~, I have 3 questions about memory based bulk copy.

1. What is the limitation count of IRowsetFastLoad::InsertRow() method before IRowsetFastLoad::Commit(true)?
For example, how much insert row at below sample?(the max value of nCount)
for(i=0 ; i<nCount ; i++)
{
pIFastLoad->InsertRow(hAccessor, (void*)(&BulkData));
}

2. In above code sample, isn't there method of inserting prepared array at once directly(BulkData array, not for loop)

3. In OLE DB memory based bulk copy, what is the equivalent of below's T-SQL bulk copy option ?
BULK INSERT database_name.schema_name.table_name FROM 'data_file' WITH (ROWS_PER_BATCH = rows_per_batch, TABLOCK);

-------------------------------------------------------
My solution is like this. Is it correct?

// CoCreateInstance(...);
// Data source
// Create session

m_TableID.uName.pwszName = m_wszTableName;
m_TableID.eKind = DBKIND_NAME;

DBPROP rgProps[1];
DBPROPSET PropSet[1];

rgProps[0].dwOptions = DBPROPOPTIONS_REQUIRED;
rgProps[0].colid = DB_NULLID;
rgProps[0].vValue.vt = VT_BSTR;
rgProps[0].dwPropertyID = SSPROP_FASTLOADOPTIONS;
rgProps[0].vValue.bstrVal = L"ROWS_PER_BATCH = 10000,TABLOCK";

PropSet[0].rgProperties = rgProps;
PropSet[0].cProperties = 1;
PropSet[0].guidPropertySet = DBPROPSET_SQLSERVERROWSET;

if(m_pIOpenRowset)
{
if(FAILED(m_pIOpenRowset->OpenRowset(NULL,&m_TableID,NULL,IID_IRowsetFastLoad,1,PropSet,(LPUNKNOWN*)&m_pIRowsetFastLoad)))
{
return FALSE;
}
}
else
{
return FALSE;

Lock Pages In Memory Option On SQL 2005 STD 64-bit With W2K3 R2 Standard 64-bit - Does It Work?

Nov 9, 2007

Hey Folks -

I'm setting up a new production SQL 2005 64-bit server running on a dedicated Windows 2003 R2 Standard system w/8GB of RAM.

I've enabled the "Lock Pages in Memory" option (http://msdn2.microsoft.com/en-us/library/ms190730.aspx) but when I run dbcc memorystatus all of my AWE counters show 0.

According to http://blogs.msdn.com/sqlprogrammability/:

"On 64 bit machines, execute 'dbcc memorystatus'. If the AWE Allocated memory is 0 then lock pages in memory privilege has not been granted to the service account or it has not taken effect. "

Does the "Lock Pages in Memory" option work on W2K3 R2 Standard? Just searching across the web I find different answers. In some places it clearly says that Lock Pages in Memory only works on W2K3 Enterprise systems. In other places it says that it should work on any Windows 2003 64-bit OS.

Does anyone have any ideas? Assuming we cannot "lock pages in memory" due to the Windows 2003 Standard OS, are there any other memory management recommendations out there?

thanks!

Changing Index Option

May 30, 2007

We have a database at work that holds URL's to documents that people must read and sign off on. The problem is when a duplicate URL is entered because the document has been updated the system will not add it to the database because it is a duplicate key. I can tell from looking through the sql files that it is not a primary key so from what I've read I need to turn on IGNORE_DUP_KEY for the index's options. Is there a way I can just open a window and turn this on or do I have to somehow run a script to set it up? If so, could someone explain how to run the script? Thanks

Using The ONLINE Option The Alter Index Rebuild

Jul 9, 2007



I do a lot of index maintenance and started testing rebuilding my indexes with the ONLINE option, but noticed an increase in record size by 14 bytes. The issue I have is that for each index you build the ONLINE option, you add 14 bytes for row. After the index rebuild is done, normal transaction updates drop the additional 14 bytes.

The act of adding and dropping 14 bytes would cause fragmentation and uncompressed data. Is this correct or do I have something wrong?

FILENAME Option In CREATE DATABASE Statement

Nov 9, 2004

Hi,

I have a problem with CREATE DATABASE statement, since it needs to specify the absolut path for a file in the FILENAME= option. I would need instead a relative path, i.e. only the name of the file because the script that launch this SQL command is dependant on the installation path decided by the user, during the installation.
Is there a way to pass to the FILENAME only the name of the file?
Hope to have been clear :-)

Thanks in advance

SQL 2012 :: AlwaysOn - Readable Secondary Option

Aug 21, 2014

In always on under availability group server name properties can see the option Readable Secondary. In that for secondary server the Readable Secondary Option is YES and for Primary it is Read-Intent. I believe Read-Intent allows only read only connections and YES allows all user connections.

SQL In-Memory :: Table Memory Optimization Advisor Validation Passed But Cannot Migrate

Jul 13, 2015

I am looking to test this feature - and the "Transaction Performance Collector" has recommended me a table to port to In-Memory OLTP. 

I have now tried the "Table Memory Optimization Advisor" tool.

After a couple of tweaks to the table design - the tool is now passing validation but the tool is not allowing to progress to the next step:

Could it be down to not having enough memory? But would this not show in the advisor?

Using OPTION Clause Within CREATE FUNCTION Statement For Inline Table Functions

May 13, 2008

Hi!

I need to expand resursion level for resursive CTE expression within CREATE FUNCTION statement for inline table function to a value greater than default. It turns out that OPTION clause for MAXRECURSION hint perfectly works if I use it outside CREATE FUNCTION (as well as CREATE VIEW for non-parametrized queries), but it does not within CREATE FUNCTION statement - I'm getting error:

Msg 156, Level 15, State 1, Procedure ExpandedCTE, Line 34

Incorrect syntax near the keyword 'option'.

Here is the function:


create FUNCTION [dbo].[ExpandedCTE]

(

@p_id int

)

RETURNS TABLE

AS

RETURN

(

with tbl_cte (id, tbl_id, lvl)

as

(

select


id, tbl_id, 0 lvl

from


tbl

where


id = @p_id

union all

select


t.id, t.tbl_id, lvl + 1
from

tbl_cte
inner join tbl t


on rnr.tbl_id = tbl_cte.id

)

select


id, tbl_id, lvl

from


tbl_cte

option (maxrecursion 0)

)


Please help!

P.S.
I'm really sorry if it is about syntax, but I could not find it in the documentation.

AWE/Lock Page In Memory Drawbacks? Min/Max Settings, Memory Issues

Oct 11, 2007

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.

SQL 2012 :: Enabling SSL Encrypted Connections Without Using Force Encryption Option

Apr 1, 2015

I have a customer who is looking to encrypt their applications connection to the back-end SQL server. I've gotten a valid certificate for the server from a trusted CA, and it's installed on the server (shows up in Personal certificates in the Certificate MMC when selecting the computer) and I can choose it in the drop down on the certificates tab of the SQL Network protocols properties in Configuration Manager.

Now, my question: If I select the certificate but do NOT enable the "Force Encryption" option, the client will be able to request encryption on their end, and the connection will then be encrypted. If the client (other applications) do NOT request encryption, they will still be able to connect, but their connection will be un-encrypted. URL....

Lastly, I could've swore I had found some information indicating that some methods of establishing a connection to SQL can fail when Force Encryption is enabled, as the method doesn't support SSL encryption.

SQL Server 2012 :: Running Sum With Reset Option And BULK Update

Jul 22, 2015

I have come up with an issue where I want to update data in a table using bulk/SET update to get the result shown in below code with output in column titled "Arrear Amt".

Please use this test data.

CREATE TABLE ##vOD_Calc
(
Seq_No INT ,
Contract_id INT ,
Rental_id INT ,
Actual_OD INT ,
Logic_OD INT ,
Due_dte DATETIME ,

[Code] .....

Logic required is that once the sum of column [ArrearAmt] of current row and all previous rows becomes greater than $100 then column [ChArrrearAmt] should show that summed up value and in else case the column [ChArrrearAmt] should show the same value as that of column [ArrearAmt].

Once the column [ChArrrearAmt] reaches the threshold of $100 then the same cycle should start again i.e. in above example rental#1 had $37.17 < $100 then rental#1 + rental#2 is also < $100 and at rental#3 sum of rental#1, rental#2 and rental#3 becomes $111.51 which is greater than $100 so its updated in column [CHArrrearAmt]. The same cycle start overs from rental#4 onwards however the summation of [ArrearAmt] will now begin after rental#4 onwards and not from the starting.

Below is the loop based SQL script which handles the above situation, however in BULK its a total deterioration of performance if thousands of rows are to be processed i.e. with a contract having multiple rentals.

The case here is that I have to use the result of previously updated column value of [ChArrrearAmt] to take decision for the next row, however with BULK update since the row is not yet updated with latest amount therefore the decision on next row is also giving wrong result.

This is the code with which I have achieved to update the column 'chArrear Amount', however its a loop based solution and performance killer.

INSERT INTO ##vOD_Calc_loop
( Rows_count ,
contract_id
)
SELECT COUNT(*) ,
T.Contract_id
FROM ##vOD_Calc T
GROUP BY T.Contract_id

[Code] ....
