Check out Christoper Lawson's Oracle performance tuning book - it's
very good on the basics of this subject.

When asking database related questions, please give other posters
some clues, like OS (with version), version of Oracle being used and DDL.
Other trivia such as CPU, RAM + Disk configuration might also be useful.
The exact text and/or number of error messages is useful (!= "it didn't work!"). Thanks.
Furthermore, as a courtesy to those who spend time analysing and attempting to help,
please do not top post and do try to trim your replies!

Query to Find what SQL Server services running, what status and with what service account

I need to check what SQL Server services are running(engine,agent,IS,AS,RS,browser and Full text) and what is the present status and what service accounts are been used by them on several servers in a single shot.
Could any one help me in finding a good script for the same.

I have been looking for the same thing, the issue I am running into is finding the Actual Service Name. I know this question is old, and I personally do not understand the reply.

Hi Vaibhav,
Manu's has copied as a part of the below code.
create table MyTable
PKey int identity(1,1),
CustID int,
FirstName varchar(10),
LastName varchar(10),
Main varchar(10),
Department varchar(10)
Insert into MyTable--(CustID,FirstName,LastName,Main,Department)
select 101, 'aaa','bbb','VM','Marketing' union

select 102, '', 'yyy', 'Main', 'Marketing' union
select 102, 'xxx','','','' union
select 103, 'ppp', 'qqq', '', 'HR' union
select 103, '', '', 'MF', '' union
select 104, 'mmm', 'nnn', 'f', 'dept'
SELECT * FROM MyTable;
;WITH cte AS
SELECT DISTINCT
MAX(PKey) PKey,
CustID,
MAX(FirstName) AS FirstName,
MAX(LastName)AS LastName,
MAX(Main) AS Main,
MAX(Department) AS Department
FROM mytable
GROUP BY CustID
MERGE mytable AS Tar
USING cte AS Src
ON Tar.PKey = Src.PKey
WHEN MATCHED THEN
UPDATE SET Tar.CustID = Src.CustID, Tar.FirstName = Src.FirstName,Tar.LastName = Src.LastName, Tar.Main = Src.Main,Tar.Department = Src.Department
WHEN NOT MATCHED BY SOURCE THEN
DELETE
SELECT * FROM MyTable
DROP TABLE MyTable;
If you do care about the Identity Pkey, as per the expected output, my understanding on your logic is like below.
;WITH cte AS
SELECT PKey, CustID,V1,V2,V3,V4,ROW_NUMBER() OVER(PARTITION BY CustID ORDER BY v1+v2+v3+v4 DESC) AS RN
FROM MyTable

Query to find duplicate referance numbers

Dear,
We have somehow managed to create the same sales order twice or more. In the field "Customer Ref. No." we always type in BP's ref. no. So what I need is a query which will show me all open sales orders which have more than one identical "Customer Ref. No." (ORDR.NumAtCard)
So what I got so far is:
SELECT T0.[DocNum], T0.[NumAtCard] FROM ORDR T0 WHERE T0.[DocStatus] <> 'C' AND ????
Hope anyone can help. Thanks.

Hi Kjetil Sandvik,
If you want to block Sales Order with duplicare Customer Ref. No then
Try this SP.....
if (@object_type = '17')
and (@transaction_type= 'A' or @transaction_type= 'U')
begin
declare @Refno as varchar(100), @Cust as varchar(100)
if @object_type = '17'
begin
select @Refno = NumAtCard,
@Cust=CardCode
from ordr
where DocEntry =@list_of_cols_val_tab_del
if 1 != (select count(DocEntry) from ordr with(nolock) where NumAtCard = @Refno and CardCode=@Cust)
begin
select @error = 1
select @error_message = 'Customer Ref. No Should Not Be Repeated. ! '
end
end
end

Finding duplicate values in a column with different values in a different c

I'm finding duplicate values in a column of my table:
select ba.CLAIM_NUMBER from bsi_auto_vw ba
group by ba.CLAIM_NUMBER
having count(*) > 1;
How can I modify this query to find duplicate values in that column where I DON'T have duplicate values in a different specific column in that table (the column CLMT_NO in my case can't have duplicates.)?

Well, you can use analytics assuming you don't mind full scanning the table.....
select
count(owner) over (partition by object_type),
count(object_type) over (partition by owner)
from all_objects;You just need to intelligently (i didn't here) find your "window" (partition clause) to sort the data over, then make use of that (the analytics would be in a nested SQL and you'd then evaluate it in outside).
Should be applicable if i understand what you're after.
If you post some sample data we can mock up a SQL statement for you (if what i tried to convey wasn't understandable).

Query to find the Views and synonyms that are accessing through db_link

HI all,

Edited by: Deepak_DBA on Dec 10, 2010 5:38 PM

On the second database (B) use this query to find the SQL which used by the schema A (DB LINK USER). Check the SQL_FULLTEXT column.
select sql_fulltext,sql_id,module,parsing_schema_name,parsing_user_id,first_load_time,loads,users_executing,rows_processed,plsql_exec_time,sorts,fetches,invalidations,parse_calls,cpu_time,elapsed_time,disk_reads,buffer_gets
from V$sqlarea
where parsing_schema_name = 'A' --and to_char(first_load_time,'dd/mm/yyyy') like '%11/08/2007'
order by first_load_time desc;

I am using ORACLE 11gR2 If you're licensed for Diangnostics pack then you might want to look at the AWR tables, e.g. DBA_HIST_SQLSTAT and cross-reference with DBA_HIST_SNAPSHOT.
By this will i get the top 5 consumed queries of DEV user in the whole session or its just the top 5 queries at that particular time. The "executions" columns in this query, does it mean that the no. of. times the query has executed... This will get you a random 5 queries that were first parsed by DEV. Depending on your application code/structure, it may well be that all code (except for system-recursive sql) executed by DEV is parsed by DEV, and all code parsed by DEV is executed by DEV but this isn't true for all.
In terms of top N queries, you need to ORDER BY and then restrict by ROWNUM at an outer level to the ROWNUM otherwise the ROWNUM filter is applied before the ORDER BY.
i.e.
SELECT *
FROM
(SELECT ...
FROM ...
WHERE
ORDER BY...)
WHERE ROWNUM <= ....
The "executions" columns in this query, does it mean that the no. of. times the query has executedYes.

How to find out all SQLs executed by a procedure

I need to find out all SQLs executed by a procedure. I can trace and check but in my case the issue happened 4 hours back and i know what procedure was causing it. There are multiple dynamic queries fired from this procedure. I need to track down all SQLs fired by this procedure constructed dynamically during the time issue was happening.
I have the sql_id of the statement which was executing the procedure. How do I track down all "child" SQLs using this sql_id?
Will appreciate any pointers.

Thanks for your suggestion and looking into this.
We already have that functionality built in. Version is 10.2.0.3...But the issue is the proc is called thousands of time in a day and we can not keep the tracking of sqls and parameters passed on all the time. When the issue happened we were not tracking. The bind variables are not captured as the SQL is constructed within the proc by looking up the values dynamically from secondary tables dynamically based on the parameters passed to the procedure. Now the SQLs which are generated from the proc will have the bind variables captured as they will come as predicates and will have no clob types (condition for the binds to be captured).
I need a query to track down all "child" SQLs by using the sql_id of the parent process which is the procedure's sql_id.
