Storing large graph in
relational form doesn't allow us to perform graph operations such as
shortest path quite efficiently. I'm wondering if storing the graph as
objects would be better? How should I design the schema? Thanks!
I'm hoping to create a graph with durations as bar graphs and % met as a line graph. Is this possible in BIDS?
View 1 Replies View RelatedI'm using SQL Server 2012 Analysis services in Tabular mode and connected to Oracle Database and while importing, I'm getting below error after importing some rows.
OLE DB or ODBC error: Accessor is not a parameter accessor.. The current operation was cancelled because another operation in the transaction failed.
I'm investigating my production server because there appears a deadlock every day. So, in SQL Profiler, I use the the Deadlock graph to capture the trace in a file.
When I click on the textdata to see the graph an error appears:
- Failed to initialize deadlock control.
Cannot find process victim in process list.
I also get the following error from another deadlock:
- Failed to initialize deadlock control.
Object reference not set to an instance of an object.
I stopped my trace, so this can not be the problem.
Does anybody knows why I can't see the graph?
I also captured the trace in a table and then used the following query to see it in xml:
select convert(xml,textdata)
from TableName
This works fine.
I'm trying to figure out how to determine why the same database is fast on my desktop but slow on a robust multiprocessor win2003 server.
I have a complex proc that takes about 27 seconds on my desktop sql server but takes almost 5 minutes on the server. The server processors are running at about 1% utilization while the proc is running.
Any ideas on how to troubleshoot this extremely poor performance?
On my development machine (XP Pro), when I run several reports in a loop, my connection count (in performance monitor) climb up to around 25 then immediately drop back to 1 when the reports are done being generated.
On our production server (WinServer 2003, IIS6) the SQL connection count climbs up to around the same number, then holds there for a few minutes. I know I am closing the connections properly in my code because they clean up fine on the development machine.
I'm sure this is a timeout setting or an IIS 6 option I need to tweak. How can I make my production machine remove those connections faster?
I have a very unusual situation - we converted a client from DB2 7.2 to MS SQL Server 2000, SP3. There is one report that runs very quickly when ran on the Database Server, but it takes a long time to complete when it is ran from a client system. This query is ran from within the application and not from within Query Analyzer.
Has anyone else here ever encountered this issue? What did it turn out to be? I am leaning away from it being a network issue.
Thanks in advance.
I've been using full-text for quite some time, but I switched to another product for quite some time. The reason is that microsoft full-text doesn't offer the feature where one can get a resultset of page x out of y pages, i.e: give me top 100 matches of page 125 out of 5000 pages. I disappointedly waited for SQL Server 2005 and now it doesn't seem to support in sql server 2008 full-text search either. I had to get all 5000 pages of data, then jumped to page 125 to get just 100 records of that page--had to go get a coffee and came back for a 2+ millions rows table. Customers want the result in a split of a second.
Anyone knows if the final version of sql server 2008 will have better support for paging and getting top x rows? I scanned through 2008 BOL and didn't see any change from sql server 2005 or even sql server 2000 full-text search. (one improvement in sql server 2005 over sql server 2000 was the speed of populating large catalog and multiple languages support)
Thanks,

On the same server DatabaseA the query runs in less than 5 seconds. On DatabaseB the query times out. I can not see the execution plan for the query that times out. I am executing the query using SQL Server MGMT Studio. I have rebuilt all of the indexes, stats updated usage. Still no luck. I have checked all of the database setting and they are the same. If I comment out theste 2 lines "AND ((PostTitle LIKE '%flood%') OR (PostText LIKE '%flood%')) " the query run like it should and uses an execution plan all most the same as when using DatabaseA. Any pointers in the the right direction would be greatly apprecited!!!

My database server memory utilisation is growing faster from past 1 week. it remained same for 1 week around 55% and now it is going to 70% and increasing.
Total OS memory is 32GB and I kept cap for sql server memory upto 29GB. Dont know what to do..
In an ASP, I have a dynamically created SQL statement that amounts to "SELECT * FROM Server1.myDB.dbo.myTable WHERE Col1 = 1" (Col1 is the table's primary key). It returns the data immediately when executed.
However, when the same record is updated with "UPDATE Server1.myDB.dbo.myTable SET Comments = 'blah blah blah' WHERE Col1 = 1", the page times out before the query can complete.
I watched the program in Profiler, and I saw on the update that sp_cursorfetch was being executed as an RPC once per each row in the table. In a table of 78000 records, the timeout occurs well before the last record is fetched, and the update bombs.
I can run the same statements in Query Analyzer from a linked server and have the same results. The execution plan shows that a Remote Query is occurring on the select that returns 1 row, and a Remote Scan is taking place on the update scanning 78000 rows (I guess this is where all the sp_cursorfetch calls are happening...?).
How can I prevent the Remote Scan? How can I prevent the execution of the RPC sp_cursorfetch for each row in the remote table?
Thank you!
I’m looking for clearity on partition switching. The idea is to use many BULK INSERT statements into table dbo.X_n in parallel and when BULK INSERT for table dbo.X_n is completed, switch dbo.X_n into dbo.bigdaddy. I think this is the fastest way to upload a couple hundred GB of data.
In learning about partition switching (in part) from The Data Loading Performance Guide under Partition SWITCH, I hear the instructions to say copy the main table exactly to become a target. But in that same step (#1), I read that we need to change the default file group of the target (dbo.X_n) from the default file group. Then it says I need to match indexes and lists the filegroup as something we need to match with the main table.
As an overview of the partition switching strategy, I think the whole point of BULK INSERT with partitioning is to have seperate files (in same group) to enable concurrent uploading where each table has its own file. Once the upload is completed to a table (dbo.X_n) then we do the partition switch into the main table (dbo.bigdaddy). The data we just uploaded doesn’t actually move, just the metadata for it.
“Don’t have the same filegroup on your target as the main table. You must have the same filegroup on your target as the main table.”
hi all ,
I created the trigger by the statement
CREATE TRIGGER trigname ON tablename FOR
INSERT , DELETE AS .... END GO
1) Can I enable and disable a trigger in Microsoft SQL Server as in Oracle ?
Through SQL Query Analyser , I tried this sql statement ...
--ALTER TRIGGER trigname ENABLE ---
and get the error ------- Incorrect syntax near 'ENABLE'.
2) Can I invoke a .bat file in a trigger event ?
OR
Can I load and invoke a java class in Microsoft SQL Server .

Hi,
View 4 Replies View RelatedHello,
I am setting up a new server with Windows Server 2003 x64 bits and SQL Server 2005 x64 bits. Under 32 bits of Windows we normally use /3GB and enable AWE under SQL Server (both SQL 2000 and SQL 2005) and allocate 6 GB of fixed memory to SQL Server.
Does any one know whether I should do the same thing under the x64 bits platform. I read some articles on the web that it is no longer required to use AWE under SQL 2005 x64 bits??
Please advise.
Thanks.
Q1: Can I just open these protocols I need (see web links below) and then close them down again after SQLCacheDependency has been enabled? Note: The website (asp.net 2.0/SQL server Express) operates OK right now with asp.net - but it does not have SQLCacheDependency enabled.
Problem: When I try to do this I keep on getting this error message:
"An error has occurred when 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."
None of these 3 commands have worked (all give the same message above):
aspnet_regsql.exe -U user1 -P pwd1 -S server1/SQLEXPRESS -d myDBName -ed aspnet_regsql.exe -E -S server1/SQLEXPRESS -d myDBName -ed aspnet_regsql.exe -E -S .SqlExpress -d myDBName -ed
I am trying to run these commands via a MSTSC connection. Q2: Is that (terminal server) the problem (the "remote connection") complained of above ?
This is the command that worked on my local dev machine:
aspnet_regsql.exe -E -S .SqlExpress -d myDBName -ed
Q3: Must I really go through the procedure "How to: Configure Express to accept remote connections" at:
http://support.microsoft.com/default.aspx?scid=kb;EN-US;914277http://blogs.msdn.com/sqlexpress/archive/2005/05/05/415084.aspx
I don't really want to have SQL server accepting any connections as the last time it was listening on these ports we had so many attacks being made that it was filling up the logs!
What I can't understand is that every night the database is backed up with the following command line code (operating as a Scheduled Task):
sqlcmd -s server1/SQLEXPRESS -i MW4BAK.SQL -E
Q4: So if the server is happy receiving commands from 'sqlcmd.exe' why does it have such problems with 'aspnet_regsql.exe'
Q5: If I grouped those statements I need to setup SQLCacheDependency under a Scheduled Task would they work (as there would presumably be no remote connection then) or is it something in the nature of the connection established which allows sqlcmd.exe to work but stops aspnet_regsql.exe?
Hi guys
Apologies if this is the wrong place to be posting this but I have posted on a few forums and have not had any usable answers to this question, so I am hoping you guys will be able to help me.
I have 2 servers that are on the same domain. My ASP.NET application is running off the first which has .NET 2.0 installed, and I have an SQL Server 2000 db on the other. Whenever I try to connect I get the following error: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. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)
The connection works when I run the project in VS Development Server on my work computer, but as soon as I upload to the server I get this error.
I have scoured Google but all of the sites I come across are for SQL Server 2005 and are just not suitable for solving the issue on 2000.
Any help would be greatly appreciated as I cannot continue my current project until this issue is resolved.

The following is from an accidental dba perspective.To enable RCSI on a database, referencing these two parameters:
is_read_committed_snapshot_on (value 0 or 1)
and
snapshot_isolation_state (value of 0,1,2 or 3) - based on specific needs. At a minimum, it should be a 1..Both parameters are required.
the disable trigger will be enable again.Because I already disable the trigger on last month, but when I check through the database, it enable again.I understand that, when we restore the database, all the trigger will be enable.How about SQL Cluster? will it enable the trigger??

I am following the instructions laid out in the MSDN article
http://msdn2.microsoft.com/en-us/library/ms190640.aspx
and am finding results that are confusing me. The primary server's database's log-shipping settings is set to copy the Transaction Log backups to a UNC share on the secondary server. The secondary server does not have an instance of the backup database yet, so I specify "Yes, generate a full backup of the primary database and restore it into...." in the Initialize Secondary Database tab.
Under the Copy Files tab, i make the secondary server additionally copy the original log file location (e.g. \secondarylogship - d:logship) to another extra location (e.g. d:logship
estore).
When the processed is kicked start, it appears to report everything is successful. However the primary database properties show that "Enable this as a primary database in a log shipping configuration" is checked off. There is no SQL Server Agent job to back up its Transaction logs. Over at the secondary server, there are the three expected Copy, Restore, and Alert SQL Server Agent jobs. The resultant database is in a perpetual Restoring... state and nothing can be done to it.
I also noticed the Restore job ran before the Copy job when i checked the Job History of those jobs. I would have thought Copy should be done before attempting a Restore.
Can anybody explain what behaviour is being observed here? Thanks.

HI all,
I would like to ONLY allow using SQL Server authentication and restrict Windows Authentication. At the moment, i set the security to "SQL server and windows authentication". Now, even though i set the password for "sa", i can ignore the SQL Server authentication and just use Windows authentication to manipulate database objects???
can anybody give some suggestions to restrict windows authentication and allow sql server authentication?.

How can I create a row wise trigger in MSSQL Server .
CREATE TRIGGER trigName ON tableName for
INSERT , UPDATE , DELETE
AS ...
For a multiple delete , I got only one trigger invocation .
But I need individual trigger calls for each row ...
How can I do this in t-sql ?
Is there any usage like FOR EACH ROW in Oracle ?
Is it possible through INSTEAD OF TRIGGER ?
Please help !!!!!!!!
Hi
I am doing a task for synchronize data between SQL server 2005 and SQL Mobile.
Created a publication in my SQL server 2005
Created a subscription in my device thru coding. The code is below.
SqlCeReplication repl = null;
try
{
repl = new SqlCeReplication();
repl.InternetUrl = @"http://localhost/TestFirst/sqlcesa30.dll";
repl.Publisher = @"zcs6";
repl.PublisherDatabase = @"TestNow72743";
repl.PublisherSecurityMode = SecurityType.DBAuthentication;
repl.PublisherLogin = @"sa";
repl.PublisherPassword = @"Test";
repl.Publication = @"TestFirst";
repl.Subscriber = @"TestNow7274310";
repl.SubscriberConnectionString = @"Data source = 'TestFirst.sdf';";
if (!File.Exists(@"TestFirst.sdf"))
repl.AddSubscription(AddOption.CreateDatabase);
repl.Synchronize();
}
catch (Exception ex)
{
MessageBox.Show(ex.Message);
}
finally
{
repl.Dispose();
}
If I run this code from my device the replication work successfully. Now I am calling synchronize from device.
My question is How can i start synchronization from server side. Is it possible to do that from server side?
I have a Windows NT group that is used to delegate certain database responsibilities to other members of staff and I am trying to grant permissions for the members of the group to be be able to establish database mirroring sessions, as in run the following:
ALTER DATABASE <database>
SET PARTNER = 'tcp://principal_server.domain.com:port';
Although the group has db_owner role membership to the user database which grants the ALTER permission on the database, the following is being generated in the error log when they get to this step on the intended Mirror instance after restoring the database correctly in preperation:
SqlDumpExceptionHandler: Process 59 generated fatal exception c0000005 EXCEPTION_ACCESS_VIOLATION. SQL Server is terminating this process.
* *******************************************************************************
*
* BEGIN STACK DUMP:

* Exception Address = 00007FF9A6AF838C Module(sqlmin+000000000003838C)
* Exception Code = c0000005 EXCEPTION_ACCESS_VIOLATION
* Access Violation occurred reading address 00000000000000D8
* Input Buffer 210 bytes -
* alter database <redacted> set partner = '<redacted>';
As you can see, the statement is denied to the user. There are no issues with the database as I am able to run the same query successfully using my own sysadmin account after the failed attempt. What other minimum permissions the group might need to successfully enable them to setup a mirroring session?

SQL profiler shows that batch was completed (but rowcount shown in process progress log is too small).
Analysis
Services profiler shows no messages at that time at all. It just shows
messages when it started, and when I restarted the processing.
The Analysis trace appears to be stopped when processing stops with "Server: the operation has been cancelled."This
is an occasional error and sometime occurs within 15-20 minutes from
starting to process. It could fail on 1st partition in the process list
, or on some partition in the middle. Some partitions might run for a
few hours and not error out, but sometimes it fails quickly.I was not sure if this is an issue with the underlying fact data, so I broke up the last partition where it failed into 5 smaller partitions, they processed OK separately.I think restarting SQL Server and SSAS helps to process a few more partitions. Some that failed with this problem process OK after restart, but some fail again.

I have an UPDATE statement that joins two table by SendId. One table, I'll call it T1, has a clustered index on SendId ASC. The other table I will call T2 also has a clustered index on SendID ASC. All the columns from T2 are used to update T1. The execution plan shows a Clustered index scan on T2 and a Clustered Index Seek on T1 going into a Nested Loops inner join. Immediately following is a Distinct Sort that is done on SendId ASC. Why the Distinct SORT if the tables are already ordered by SendID?
