Hello ,
I would like a script for MSSQL 2000 for collection of utilization data for cpu and ram. I need to have the data from several servers.
This data for all servers should be stored in a database. I am looking for 10 minute increments.
How can I go about this.
Thanks
Hi all,
I would like to create a stored procedure that will get the statistics of all the table in my database.
e.g.
Get the record count of each table in the database
Please help me.
Thanks in advance.
Does anyone know of a tried and tested method for collating stats from SQL Server databases. I have a no. of databases hosted on a single server, servicing a no. of applications. I need to find out the following:
CPU usage of each application on the server
Memory usage of each application
etc
Thanks
Is it true that Update Statistics perform record commits if a query is outstanding?

Hi pals,
Basically i am from Oracle background. I need some help.
In oracle we gather the statistics of a table as
SQL> analyze table <tname> compute statistics for all indexes;
or
SQL> EXEC DBMS_STATS.gather_schema_stats('SCOTT')
I want to gather statistics for a particular database say."pubs" for example.
How to do that?
Any suggestions are appreciated.
Thanks.

Hi all,
I have an dtsx (SSIS) for "clone" manually Sql server database to another.
How I copy all stats from one database to another ? I have problem with "auto stats".
When I try DROP statitics for auto stats I get this error:

Cannot DROP index 'dbo.ACTIVIDAD_PROVEEDOR.PK_ACTIVIDAD_PROVEEDOR'. Not statitics collection.
What can I do ??

I have a report that was designed using SQL Reporting Services that sits on a SQL reporting server. It's nothing too exciting, it is essentially a three page application with legal jumbo on pages 2 and 3 and applicant data in fields on page 1.
We use rectangles to force page breaks to page 2 and to page 3.
When running the report on the report server, it shows and prints fine.
When running the report from the QA website internally, it shows and prints just fine.
When running the report from the production website from a machine internally, it shows and prints just fine.
When running the report from outside of the company network, the report is jacked. It obliterates large chunks of text, crams text together, and creates blank pages.
I need help in determining where I even begin with trouble shooting this!
This is probably a simple question, but I am relatively new using SQL Queries.
I tried this which gives me half of what I need... SET STATISTICS IO ON
I also need my query to return the run time that it took to run my query.
Can someone help me please?
Thanks!

I'm fairly new to SQL Server and I'm just wondering if it's possible to Update Statistice for all indexes somehow? I'm looking at the Update Statistics command and it doesn't seem to be possible.
The situation we have is a reporting DB that basically has all it's tables truncated and remade every night by some DTS jobs that import from another datasource and change the data and build some denormalzed tables etc.
Some of the large Insert operations go from taking 8 mins to taking several hours sometimes and updating the stats seems to fix the problem for a while. So I'd like to make sure the optimizer has all the latest stats for all tables.
Any other advice would be appreciated.
Cheers.

Found the SQL that caused it - anSP.Ran the sp by hand, no messages come up - error 208 logged in thetrace.Couldn't work it out. Then noticed stats missing on one column.Created the stats manually - and suddenly the 208 error stops. Wtf?Is this predicted/expected behaviour?

I am in the middle of a major migraton project, moving from x86 SQL 2000 to IA64 SQL 2005. I have a business need to link to several legacy servers. I have a number of problems I am trying to solve.
1) Linking a Kerberos server to a non-Kerberos server.
2) Linking x64 or IA64 servers to x86 servers.
3) Linking SQL 2005 to SQL 2000.
Two of the errors I am encountering are:
------------------------------
TCP Provider: An existing connection was forcibly closed by the remote host.
Login failed for user '(null)'. Reason: Not associated with a trusted SQL Server connection.
OLE DB provider "SQLNCLI" for linked server "SCDC250DB" returned message "Communication link failure".
(Microsoft SQL Server, Error: 10054)
------------------------------
And
------------------------------
The OLE DB provider "SQLNCLI" for the linked server "SCDC250DB" reported an error. Authentication failed.
Cannot initialize the data source object of OLE DB provider "SQLNCLI" for linked server "SCDC250DB".
OLE DB provider "SQLCLI" for linked server "SCDC250DB" returned message "Invalid authorization specification".
(Microsoft SQL Server, Error: 7399)
If someone has worked through these problems before, I would appreciate it if you could direct me to the relevant documentation to resolve these issues.
Thanks!

View 2 Replies View RelatedIs an index based on a smallint (16 bit) really faster than an index based on an int (32 bit)
If so, how much...
Four tables
Table A: ID smallint (PK)
Text varchar(50)
Table B:ForeginID smallint (indexed - non unique)
Text varchar(50)
rowID int (PK)
Table C: ID int (PK)
Text varchar(50)
Table D:ForeginID int (indexed - non unique)
Text varchar(50)
rowID int (PK)
Table A and C contain identical data
Table B and D contain identical data
(Tables A and B were filled and then copied to Tables C and D)
Tables A/C are loaded with 64,000 records (-32,000 to 32,000)
Tables B/D are loaded with 6,400,000 records ForeginID loaded randomly with values between -32,000 and 32,000
The purpose of this test is to find out if identical queries joined on a smallint are actually faster than int based.
I ran 3 queries on each set:
- Full select
- Select on ID/Foregin ID
- Select on Table2 RowID joined to table 1
Here are the queries:
#1. Full select (smallint) - grouped to limit result set
-----------------------------------------------------------
SELECT intAID, COUNT(intBID)
FROM TESTintA
INNER JOIN TESTintB ON intAID = intBID
GROUP BY intAID
ORDER BY COUNT(intBID) desc
#2. Select on ID/Foregin ID (smallint)
------------------------------------------
SELECT intAID, intBID, strATXT, strBTXT
FROM TESTintA
INNER JOIN TESTintB ON intAID = intBID
WHERE intAID = 29120
#3. Select on Table2 RowID joined to table 1 (smallint)
------------------------------------------
SELECT intAID, intBID, strATXT, strBTXT
FROM TESTintA
INNER JOIN TESTintB ON intAID = intBID
WHERE intPK = 1050
#4. Full select (int) - grouped to limit result set
------------------------------------------
SELECT lngCID, COUNT(lngDID)
FROM TESTlngC
INNER JOIN TEXTlngD ON lngCID = lngDID
GROUP BY lngCID
ORDER BY COUNT(lngDID) desc
#5. Select on ID/Foregin ID (int)
------------------------------------------
SELECT lngCID, lngDID, strTXTC, strTXTD
FROM TESTlngC
INNER JOIN TEXTlngD ON lngCID = lngDID
WHERE lngCID = 29120
#6. Select on Table2 RowID joined to table 1 (int)
------------------------------------------
SELECT lngCID, lngDID, strTXTC, strTXTD
FROM TESTlngC
INNER JOIN TEXTlngD
ON lngCID = lngDID
WHERE intPK = 1050
Here are the results: (run multiple times to verify)
#1. Full select (smallint) - grouped to limit result set
-----------------------------------------------------------
(8 seconds) - before computing statistics on table
(13 seconds) - after computing statistics on table
#2. Select on ID/Foregin ID (smallint)
------------------------------------------
(0 seconds)
#3. Select on Table2 RowID joined to table 1 (smallint)
------------------------------------------
(0 seconds)
#4. Full select (int) - grouped to limit result set
------------------------------------------
(8 seconds) - before computing statistics on table
(7 seconds) - after computing statistics on table
#5. Select on ID/Foregin ID (int)
------------------------------------------
(0 seconds)
#6. Select on Table2 RowID joined to table 1 (int)
------------------------------------------
(0 seconds)
Conclusion: Not only is there a negligible difference in select performance, generating stats on the smallint actually makes it slower.
(perhaps there is some kind of conversion going on here behind the scenes?)

Recently we moved few of our databases from SQL 2000 to SQL 2005 (SP 2) using backup and restore. After the restore I did Reindex and update stats on the databases. Since then we have observed performance issues on SQL 2005 databases but this performance problem vanishes the moment we run (sp_updatestats). Is this a problem with SQL 2005 that we have to run sp_updatestats 2 times a days or 3 times a day. In SQL 2000 we ran it only Once a week and still we never had any performance issues. Is there any config change we need to do to fix this problem in SQL 2005?
Thanks !
The auto stats not working

begin
insert into CUSTOMER (CUSTOMER_ID, CUSTOMER_NAME)
VALUES (@COUNT, '12345678901234567890')
SET @COUNT = @COUNT + 1
END
I then look at Tables then statistics the statistics are empty so i fire update statistics and see 1000 rows in here.
I run again the insert script
DECLARE @COUNT INT
SET @COUNT = 1001
WHILE @COUNT <= 2000
begin
insert into CUSTOMER (CUSTOMER_ID, CUSTOMER_NAME)
VALUES (@COUNT, '12345678901234567890')
SET @COUNT = @COUNT + 1
END
Look again at statistics it does not have 2000 rows in here.
If i do select * from CUSTOMER where CUSTOMER_ID = '2000' then go checks statictics it works.
I was under the impression that when you do insert or delete, update then the statistics are fired.
The sys.sysindexes rowmodctr shows the 1000 rows.
I checked the conditions that sql fires if the no of rows int able > 6 and < 500 then updates when 500 mods made.
Also if row > 500 auto update done when 500 = 20% are added
So both are met.
Anyone other any other suggestions about the auto stats ?
(Assuming SQL Server 2000, auto create statistics on, auto updatestatistics on.)DoesDBCC DBREINDEX(<tablename>)update statistics? If yes, are the statistics equivalent to thosethat would be produced by:UPDATE STATISTICS <tablename> WITH FULLSCAN

I have installed the reports for the performance dashboard and really like it!
However, I'd like to be able to clear the stats in order to run specific procedures etc and see the most inefficient parts in the specific procedure. The documentation says like this about it:
The lifetime of the DMV data depends on the lifetime of the plan in cache. You can determine how long the plan has been cached, and thus the time frame over which these resources have been consumed, by looking at the Plan Cached column
What Plan Cashed column? Can someone explain to me how to clear the stats?

Recently a production server suffered a critical blocking period and I wanted to know if I could solicit some input. It seems that a stored procedure was in the middle of recompiling while and auto update statistics started. This caused blocking for like an hour on the
single object (stored procedure) that was originally called. The table that the update occurred on and that the
stored procedure is reading form is quite large. It is 2 mil rows and about 140 columns wide. Some info from
sysprocesses is below. The table alone takes up almost 4GB of space, when looking at sp_spaceused. I have some
questions.
1. Can the update statistics for a '_WA%' stats cause
blocking on a table?
2. Does an update stats on an index survive a restart of
SQL server? We tried restarting, but the blocking did not
end.
3. If the stored procedure is running under a compile, can
the server automatically start an update stats and cause
the stored procedure to wait?
4. Can the server automatically start an update stats on
more than one column stats at a time, causing one to be
blocked by the other?
5. We had never seen this issue before going to SQL2K
clustering. Is this something specific to SQL2K and not
SQL7 ?
Thanks for your input.
