Is It Common To Have CPU Usage At 50% Constantly.
Jul 19, 2007
The comapny i work for has a server running the following.
Opteron 246x2
2 Gig memory
320 Gig Sata 2 drives
Windows 2003 Standard Edition
SQL Server 2005 Express Edition. The Free one.
There are approx 10 users that connect to the server.
There are two programs which seem to use sql server. Act 7.0 and service ceo.
When the computer is rebooted its at 0% for sqlserver.exe
Than when all connect it maxes it 50% and its steady there. Seems Service ceo affects it the most.
Told by comapny need to buy full blown sql server to resolve problem. But i dont think this is the problem.
Questions: Is it common for server to be at 50% all the time with sql server running?
And if its not is there a way to reduce the sql cpu usage.
I am new to sql server and have done alot of research and fixes. Ive unsitalled and reinstalled all sql instances and done the tweaks suggested. Any fresh ideas would be great thanks.

The TEMPDB transaction log file keeps growing.The database server is new and the transaction log was presized to 1 GB on installation. After installing a number of databases, the log file grew over a day to 38GB. Issuing a manual checkpoint was the only way to free some space to allow it to be shrunk back to a usable size. The usage of the file is still going up.
I am struggling to find what process is causing the log to be used so heavily. Looking at the log reuse wait desc for tempdb returns "Nothing" and tempdb itself isn't being used very much or growing in size.

Hello, When I am seeing SQL Server 2005 Management studio Server Dashboard> I am seeing my(USERS) databases and msdb database usage is very small % of in CPU Usage(%), Logical IO Performed (%) Usage pie chart.
90% of Total cpu usage is showing for Adhoc Queries. what excatly this means in Dashboard? if application uses more than it would have shown in Database level or not?
sicerely this dashboard is good, if any one is watching daily, please advice their experiences here.
Thanks in advance. Hail SQL Server!

I've got a little console app that basically pulls back a recordset from our SQL Server 2005, goes through each row in the dataset and may/may not insert a record into a different table in the database. We use sproc's for every transaction and I close every connection in the application. However, when the application ends, I still show connection pools open in the performance monitor. Same with websites that I know have no traffic or that have been stopped by me in IIS.Last night I showed a total of 6000+ "Current # pooled and nonpooled connections". Should I be worried about what seems to be unending growth in the connection pools? If so, how can I look to manage this better?

Hi, I've been trying to figure out this error message I'm getting.

Hello:
In my production environment, ALL OF THE SUDDEN, my backups via EM schedule tasks, fail, yet when i examine the error, it says that the DUMP/LOAD was successful. I receive the following error:

I have a database with a table called RAW, this table receives msgs via XML, sms and various other formats. The data is written into this table at a rate of approximately 50-100 rows per minute.
I have a SP which takes the data written into the raw table and performs various actions looks for account information, writes to a log table, writes to incident table’s gets GPS information and so on.
The records written into the raw table need to be processed at almost instantly with a maximum of under a minute from when they arrive into the table.
At present there is a sql agent job which executes the SP, this consist of a step to execute the SP which on completion moves to the next step which is a loop waitfor delay and then back to step 1.
The trouble is it never actually finishes and runs 24/7 there is no break point for error handling and occasionally the records that arrive in the raw table do not get processed and the job has to be restarted for it to pick them up again.
I am looking for best way to handle this process, I thought about a trigger but the performance impact on using a trigger was too heavy to consider.

Hello,
when is seemd that everything works some weird behaviours comes out.
I try to summarize the problem without to post the complete code.
Service Broker is set to have a dialog between two databases on the same SQL Server instance.
The Initiator queue has retention=on and there is an activation SP to handle errors and Target's end dialog message.
The Target queue has retention=off, MAX_READER =1 and there is an activation SP to receive the message (WAIT FOR (RECEIVE (1) ...), TIMEOUT 30000 and do something with this message (sample insert into a DB).
The conversation has a Timeout Dialog to end the dialog after a while.
The problem that the message is constantly processed. The Process doens't stop is I end the dialof after the processing either.
n.b.the Receive is within a Transation that I commit at the end.
some other informations that in the meanwhile I found out :
This was my complete WAIT FOR(RECEIVE :
WAITFOR ( RECEIVE top(1) -- just handle one message at a time
@message_type=message_type_id, --the type of message received
@messagetypename=message_type_name,
@message_body=message_body, -- the message contents
@dialog = conversation_handle -- the identifier of the dialog this message was received on
FROM [TargetQueue]
), timeout 1000;
if (@@ROWCOUNT = 0)
BEGIN
COMMIT;
BREAK;
END
IF I delet TIMEOUT 1000, everything works as expected ...
Inside if (@@ROWCOUNT = 0)BEGIN..END I wrote also an Insert into a table to see wheter the end of the queue was reached but this insert never occurs (neither with not without timeout)
I'm happy that it works what if this is the solution, it make no sense to me!
Any ideas?
Thank you!
M.B.
Thank you very much

Hello.
Let me describe first my replication setup:
- SQL Server 2005 SP1 (SP2 coming soon)
- Approximately 35 remote users (Salesrep laptop) using Pull Subscriptions
- Merge (Bi-Directional) (8 articles - tables only)
- Merge (Uni-Directional) (5 articles - tables only)
- Transactional (5 articles - tables only)
Users receive data based on their territory #, therefore they receive their customers sets of data. It happens that customer change from one territory to another but not frequently. When it happens, so far so good, the data is redirected to the new salesrep using the model we configured (Territory table with SUSER_NAME() to filter the data).
Ok, here's my problem. Since a while, I can see in the replication monitor that some users seems to log the same conflict again and again (Merge process). I mean, checking the history for many subscribers, there is always the same number in the "Conflict" colums.
As an example:
- Merge completed after processing 18 data change(s) (4 insert(s), 14 update(s), 0 delete(s), 31 conflict(s))
- Merge completed after processing 27 data change(s) (10 insert(s), 17 update(s), 0 delete(s), 31 conflict(s))
- Merge completed after processing 20 data change(s) (5 insert(s), 15 update(s), 0 delete(s), 31 conflict(s))
and so on...(Those are only 3 historical entries for a single subscriptions but there are many like that, always with the same count of conflict - vary per user). It appears to me that the same conflicts come over and over.
The thing is that if I decide to reinitialize a subscription, conflicts will disappear, therefore I know that it is not a process on the server that keeps changing the data; anyway, even if it was, changes would be applied on the subscription because the server always win in my setup.
Any idea what should I do with this? Any help would be greatly appreciated.
Thanks.

We have an issue with the Version Store growing constantly. According to sys.dm_os_performance_counters, "Version Generation rate (KB/s)" is growing, but "Version Cleanup rate (KB/s)" isn't. We use read-committed snapshot isolation
While dbcc opentran and sys.dm_exec_requests don't show any long running transactions, I wrote a query looking at sys.dm_tran_ active_snapshot_ database_transactions. This shows a number of long running transactions but, according to sys.dm_exec_sessions, they are all sleeping. The transactions that are running come and go very quickly, as I would expect.Could these sleeping transactions be responsible for preventing the version store from cleaning up?

Our report server are constantly getting the below error.
What causes this - I know how to fix it, in fact, I've automated it but why does it constantly happen on some servers? I guess I'd like to know what causes it to try and fix it at those points instead of having to fix it here. Proactively.

Trying to set up a tranform task between a mysql db using and ADO.NET connection and sql server.
My query to pull from the mysql db is something like "select x,y,z from table where last_updated" > @User::LastUpdated. This command is set up as an expression for the Data Flow Task and is the value for the [DataReader Source].[SqlCommand]
I have two questions.
Why does the package attempt a query against the mysql database all the time?
And Why is the query attempting to pull the entire table instead of having any regards for my where clause?
I've even added where last_updated > greatest('2006-08-15', '" + @User::LastUpdated to attempt to get it a where clause even when the parameter isn't set yet.
What is the trick? This is not feasible when pulling from multi-million row tables.

Hello,
I'm using SQL service Broker 2005 with ASP.NET 2.0 in order to use the sql cache dependency.
everything works fine...
I have only a doubt regarding a query that is constantly executed on mu db ( i can see it be means of the SQL Profiler)
The query is:
exec sp_executesql N'BEGIN CONVERSATION TIMER ("'') TIMEOUT = 120; WAITFOR(RECEIVE TOP (1) message_type_name, conversation_handle,
cast(message_body AS XML) as message_body from [SqlQueryNotificationService-GUID]), TIMEOUT @p2;',N'@p2 int',@p2=60000
The web application is not running from a browser ...
It this ok or I forget to clean/reset something from my web application and/or sql server?
Thank you

I just inherited a Java application with a fairly complex data modelthat does not yet have any indexes except those on primary keys. It isstill in development and before I get to do any performance testing Iwant to put some default indexes on it. I realize that this a veryvague request but it's better than nothing so I want to start withthose that are generally a good idea and then tune those areas thatrequire more fine grained approach. By the way, I'm mostly a Javaprogrammer so please forgive my DB ignorance and I thank you for anyhelp.Since the full schema is quite large I will use a simple example (fullycited below my questions). Here is list of indexes that I think wouldbe a good idea. If anyone can add to it or comment on my questions Iwould appreciate it.1. Index on primary keys in all three tables. My understanding thatthis indexing happens automatically just by declaring that a column isa PK.ALTER TABLE employees ADD PRIMARY KEY (emp_id);ALTER TABLE employee_addresses ADD PRIMARY KEY (address_id);ALTER TABLE departments ADD PRIMARY KEY (dept_id);Question: Does index get created automatically because this is a PK?2. Index on foreign keys in the children tables to prevent deadlocksand lock escalations.CREATE INDEX fk_index ON employee_addresses (emp_id)3. Indexes on common queries on all three tables.CREATE INDEX common_query_idx on employees(last_name, first_name,position)CREATE INDEX common_query_idx on departments(last_name, first_name,position)CREATE INDEX common_query_idx on employee_addresses(street, city)Question: Given that the searches can be on any field separately andin any combination should I also put an index on each columnindividually or will the composite index take care of individualsearches as well? For example, will the above indexes be sufficientfor the following SELECT:SELECT e.last_name, e.first_name from employees e, departments d,employee_addresses ea, dept_employees de WHERE e.emp_id = de.emp_id ANDd.dept_id = de.dept_id AND ea.emp_id = e.emp_id AND e.position ='master chief' AND d.dept_name = 'galactic affairs' AND ea.city='LosAngeles'4. Unique index on the association table. Again this is accomplishedusing PKALTER TABLE dept_employees ADD PRIMARY KEY (dept_id, emp_id)Question: Is the index on (dept_id, emp_id) automatic because of PK?5. The association table has to go both ways and PK takes care only ofthe first half. Thus add an index to go the other way.create unique index dept_employee_idx on dept_employee(emp_id,dept_id)Question: should I use INDEX ORGANIZED TABLE?Question: should I have UNIQUE qualifier on the second index given thatPK already takes care of it?Thanks,Robert===== EXAMPLE ======1) An employee can be in many departments and a department can containmany employees.2) Common searches for employees are on last_name, first_name,position, department_name, department_location separately and in anycombination.3) There are common searches for departments that contain certainemployees e.g. find all departments containing John Smith.CREATE TABLE employees(emp_id INTEGER NOT NULL,last_name VARCHAR(50) NOT NULL,first_name VARCHAR(25) NOT NULL,position VARCHAR(10) NOT NULL);CREATE TABLE employee_addresses(address_id INTEGER NOT NULL,emp_id INTEGER NOT NULL,street VARCHAR(50) NOT NULL,city VARCHAR(25) NOT NULL,);CREATE TABLE departments(dept_id INTEGER NOT NULL,dept_name VARCHAR(50) NOT NULL,dept_location VARCHAR(25) NOT NULL,);CREATE TABLE dept_employees(dept_id INTEGER NOT NULL,emp_id INTEGER NOT NULL,);ALTER TABLE employee_addresses ADD FOREIGN KEY (emp_id) REFERENCESemployees(emp_id)ALTER TABLE dept_employees ADD FOREIGN KEY (emp_id) REFERENCESemployees(emp_id)ALTER TABLE dept_employees ADD FOREIGN KEY (dept_id) REFERENCESdepartments(dept_id)

In my experience of going through plenty of interviews, I have came across a question that I am reminded of by someone's signature.
The common question in this instance is:
What is the advantage of a cursor over a stored procedure? Vice Versa?
I could only, in my so few experiences, have answered that stored procedure consumes less system resources than a cursor. The advantage a cursor has is record by record examination and looping capabilities.
Needless to say that whenever asked those questions, I haven't landed the position. So I'm wondering, what is the more appropriate answer?

Hi - I'm trying to construct a select statement from the following tables(see example)
_________________________________
|Customer | Product |Shop |
|----------|----------|---------|
|Customer1 | Milk |Dairy |
|Customer2 | Cream |Dairy |
|Customer3 | Milk |Dairy |
|Customer1 | Trainers |Sports|
|Customer2 | Football |Sports|
_________________________________
REQUIRED RESULT SET: Milk, Cream.
Basically I want to select all of the Products (no duplicates) where EVERY customer(1, 2 & 3) have bought a from a common shop type: i.e 'Trainers' and 'Football' should not be selected as Customer3 has not bought any goods from a sports store.
This is an example of a larger problem where there can be numerous products, customers and shops. Here's a DESCRIBE of the relevent columns in each of the tables:
CUSTOMER:
customerID
PRODUCT:
productID
customerID
shopID
SHOP:
shopID
This looks like it should be easy but my SQL isn't the best ;-)
I'd really appreciate any help you could give!!
Cheers!

I try to find the best design for a SQL Server 2005 database structure.
I have the following 'objects':
Facilities
Departments - 'dependents' of a Facility
Users
Addresses - each of the above can have none or more Addresses.
The basic tables design would be:
CREATE TABLE [dbo].[Facility](
[cFacilityID] [nvarchar](5) NOT NULL PRIMARY KEY CLUSTERED ,
[cFacilityName] [nvarchar](50) NOT NULL
)
GO
CREATE TABLE [dbo].[Department](
[cFacilityID] [nvarchar](5) NOT NULL FOREIGN KEY REFERENCES [dbo].[Facility] ([cFacilityID]) ON UPDATE CASCADE ON DELETE CASCADE,
[cDepartmentID] [nvarchar](3) NOT NULL,
[cDepartmentName] [nvarchar](50) NOT NULL,
PRIMARY KEY CLUSTERED ( [cFacilityID], [cDepartmentID])
)
GO
CREATE TABLE [dbo].[User](
[cUserID] [nvarchar](5) NOT NULL PRIMARY KEY CLUSTERED,
[cUserName] [nvarchar](50) NOT NULL
)
GO
CREATE TABLE [dbo].[Addresses](
[pkAddress] [int] IDENTITY(1,1) NOT NULL PRIMARY KEY CLUSTERED,
[cAddress] [nvarchar](255) NULL,
[cZip] [nvarchar](5) NULL,
[cEmail] [nvarchar](255) NULL
)
GO
The question regards the Addresses table:
How can I design the Addresses table(s) so I can enforce relational integrity and cascade update and delete for each Facility, Department and User tables?
I figured out the following options, but none achives my requirements:
1. An Address table for each 'object': FacilityAddress, DepartmentAddress, UserAddress with the corresponding foreign key in each Address table. This solution duplicates all the addresses fields (which are more than I showed in the example).
2. A common Addresses table with a discriminator field (1=Facility, 2=Department, 3=User). This doesn't allow me to enforce referential integrity with constraint, maybe only with triggers.
3. A common Addresses table with a foreign key for each 'object (fkFacility, fkDepartment, fkUser) allowing nulls. In this case, the 'dependence' between Facility and Department stops me to enforce cascade deletes/updates on both Facility and Department foreign key (circular...).
4. An intermediate (link) table between each 'object' and Addresses table with the foreign keys (Facility, Addresses). Again, no referential integrity.
So, is there a method to design such structure?
PS. Please keep in mind that this is just a simplified example (reduced at the key information) of my real structure.
Thanks,
Ioan

At the risk of asking a stupid question -Is anyone familiar with either a query against the systables or maybean outside tool that will provide a list of the most common joins thathave been made in user created views? I'm not talking about tablerelationships that are established at the database level, but rather,I'm referring to the ability to find which joins have been utilized inpoorly constructed databases where no relationships were establishedin the first place.Thanks in advance -Cindy T.

Hi there!
I'm working on an application designed like this:
There's a table "DailyTransations" (DT) containing daily transactions...
Then there's an archive table "TransationsArchive" (TA) with the exact same structure.
When a record is inserted in DT, it is also in TA (via a trigger) and the reporting is done against TA.
Now for performance issues, we delete from DT the records older than 2 days since they are not needed for processing.
First, what do you think of that implementation?
We thought about using partitions based on the transaction date and completely eliminate TA, but it seems once a record is assigned to a partition, it is not moved automatically...
What is the common solution for this need?
Thanks

I need to get the 5 most common occurences from a table. Not really sure of the SQL statement I would use to do that. Would someone be kind enough to throw out a select statement that would do this? psuedo code would be fine, I just need to know the jest of how to do it. I originally thought Select Top 5 would work, but then I actually started thinking and realized it wasnt it. So now im stuck. Any help would be appreciated.

I need to display the company logo on 100 odd reports that run from different folders on the report manager. Since the company logo has changed before and we had to change every report, I want the image stored on a server (with SSL on) and want the reports to point to the server. The server is going to be different in development and production environments.
When I try to add the image using "Image Wizard" I get the error "Invalid image.". The wizard wouldn't let me use a function to build the path based on the environment and select the image from the correct server. It doesn't accept anything that doesn't start with "http:" when I select "web" as the image source.
Please Help!!!
