Last Query Monitor

We have a windows application that uses 3rd party tools to access the database. The 3rd party tool is created by DevExpress.
We need something that will let us know what the queries are that are being executed against the database.
We are having trouble with the query being to slow against a certain setup:
- I have a table that is partitioned by month.
- Each month has about 8 - 10 million records in it.
Initially to do the query against the data, it was taking about 10 seconds with the application. But if I used SQL Tools or SQL Developer, the same query would take about 0.002 seconds.
I decided to take all the data from one partition and create its own temporary table. After doing this, I also created the same indexes on it, that the other table had as well. Testing the application and the SQL tools both returned in a timely manner.
One thing that I did do to the large partitioned database was run the following on it:
ANALYZE table "cust_positions" compute statistics;
After doing that, the query time for the application went from 10 seconds to about 4-6 seconds.
One thing that I have found is that SQL Developer will give hints on what indexes the database should use to get the data. The 3rd party tools don’t do this, and if it does, i have not figured out how to do it.
What I would like to be able to see is, what are the 3rd party tools actually querying on, is the Oracle optimizer actually doing anything? (Not really sure on a lot for how the optimizer works, I looked at the oracle documentation for it, and there is just too much to read)
I would like to make sure that the query being run by my 3rd party tools is using the indexes.
Thanks
Chad

Chad, what is the full Oracle version?
You should be able to use the sql trace option to trace a session and get the raw trace of the session activity. You can feed the trace file to tkprof to format it for you if you do not have experience working with trace files.
Also you can look in the v$open_cursor to see some of the SQL executed by a session. You can then run explain plan on the SQL and look for the SQL in v$sql_plan view to see what Oracle actually did with the SQL.
See your Performance and Tuning manual for information on Statspack/AWR which can be used to look at the db as a whole and which also capture heavy hitter SQL.

Hi,
Check for the consistency of the info object in RSRV.
Check the info object status in cube like any data is available or not for that info object.
Also check any parralel load is taking place in that particular cube.
Please let me know if u face probelm

For example:
i made this update :

where trial_id = cobject_id
and status = 0; /* Initial */
if NUMBERS_OF_ROWS = 0 then
end if;
how can i do this?

Get the last query from the current user

Is there a way to get the last query of the current user, so every query could be log with a database trigger?
Let's just say I execute:
DELETE xxxx;
I tried :
SELECT T.SQL_TEXT FROM V$SQLAREA T where ADDRESS=(SELECT prev_sql_addr FROM v$session where audsid=userenv('sessionid'));
But the result of this query is :
'SELECT T.SQL_TEXT FROM V$SQLAREA T where ADDRESS=(SELECT prev_sql_addr FROM v$session where audsid=userenv('sessionid'))'
Is there a way to execute a query that would return :
'DELETE xxxx'
Thanks

You could join SQL_ADDR in v$session with ADDRESS in v$sqlarea to determine the SID that executed that SQL statement last. Note that PREV_SQL_ADDR in v$session will indicate the previous SQL he executed. Though you would have to look at these tables very often to get all SQL statements issued. One note here, I think if a different user ran the SAME SQL with just bind var differences the SQL_AREA will only show the last userâs information that executed it.
BTW - it will show deletes also...

Last query(urgent)

Hi,
Can anybody help me step by step how to use last query
I have like this
I have a form .So user can search records based on query
i have like this
EMPNO EMPNAME LAST_YEAR
10 a 1991
10 B 1991
20 C 1994
If user queries on EMPNO = 10
EMPNO EMPNAME LAST_YEAR
10 a 1991
10 B 1991
I have a button name UPDATE LAST YEAR
when user press the button
EMPNO --10
from 1991 TO--1994
OK CANCEL
When user press the OK button i need to update the lastyear from 1991 to 1994
i can do this its working fine
My cocern here is when user press the OK button
It should bring up the records with 10 and update year
I mean to use the last query
Any help step by step

Please post DDL, so that people do not have to guess what the keys, constraints, Declarative Referential Integrity, data types, etc. in your schema are. Learn how to follow ISO-11179 data element naming conventions and formatting rules (you have no idea).
Temporal data should use ISO-8601 formats. Code should be in Standard SQL as much as possible and not local dialect.
What you did post is bad SQL.
The prefix “tbl-” is a design flaw called tibbling and we do not do it. We seldom use temp tables in RDBMS; it is how magnetic tape file programmers fake scratch tapes.
If the schema is correct, then SELECT DISTINCT is almost never used.
Your “bill_parent” looks like a assembly language bit flag; we never use those flags in SQL.
“Funding_Type_Status” is an absurd name for a table. A status is a state of being, not an entity. A type is an attribute property. So this table ought to be column that is either a “funding_type” or “funding_status” (with the time period for the state of being
shown in other columns). But this hybrid is not possible in a valid data model.

Last query refresh failde due to internal errors ?

Hi gurus
we are working on SRM 7.0 with PPS,
when Bidder tries to open his login page and wants to see the Rfx raised against him, He is getting error message,
" Last query refresh failed due to internal error" , some time this is due to another session witht he same query is open , but
I am getting the same error in the following situation,
suppose bidder has submittted his response and after submission he is trying to change the response and couldn't submit before the submission dead line then the version of the response will be c1, and which is not interpreted by the system, and so the error is .
Any help or advice on the issue is highly appreciated.

Query monitor

Hi,
I am new to sap bi. I know we can check the performance of the query through query monitor through rsrt. But by looking at which field we will come to know that query performance is slow in the query monitor
Thanks in advance
krish

Hi,
Goto RSRT transaction --> Give query name --> Query Disply as "HTML" > Execte + Debug> --> Continue. Qury will be executed.
Follow below steps to find out the query execution time:
Now goto SE11 > Give table name as RSDDSTAT_DM or RSDDSTAT_OLAP in BI7.0 or RSDDSTAT in BW3.x.> Display -> Contents-> Give from date and to date values as today, user name as your user ID, and give the query name in the Object name field--> execute.
Now u'll get a list with fields like Object anme(Report anme), Time read, Infoprovider name(Multiprovider), Partprovider name (Cube), Aggregate name... etc.
The time read represents the time taken to execute the query.
If the time read is less than 100,000,000 (100 sec) is acceptable. If the time read is more than 100 sec then we take decision to create Aggregates for that query to increase performance.
Hope it helps you...

Query cache,query monitor

Hi
wt is the purpose of Query monitor and query cache.. can u plz.. explain
ponts assured*
Regards
Rekha

As the verbeage indicates, query monitor is to monitor the runtime performance of BW queries. Query monitor is one of the tools in BW to monitor the query performance. The transaction to run query monitor is RSRT.
In RSRT, you can exceute queries in various modes and you can to some extent enforece a query to be executed in a certain path; For example, you can simulate the execution of q query without using a aggregate, without using cache, etc.
In monitor you can also view how the query is getting executed and diagnose the possible causes as to why a query is running slow.
Caching is to store the query results in the memory of the BW system's application server. If you cache a query, the run time performance will improve considerably, because the result ste is stored in the meonry and every time when the query is run, the OLAP engine will not have to read the data base to fetch the records.
The query caching has some limitations; if the query result changes, the cache will not help, because the new result set has to be again read from database and presented.

Displaying the Last Query Refresh date/time

Hello,
on a Webi report, is there a way to display the date/time that the underlying info provider was refreshed?

1.- Create Formula in Query (columns - Create Formula)
2.- Create Formula Variable for this Formula (Type Customer EXIT) as individual and optional.
3.- Define the code for customer exits for variables.

Get Recordcount of last Query

Hi,is it possible to get the number of records of the last SQL-Query inside a Stored Procedure.
I´m trying to get my Stored Procedure faster and the problem is, that there are many code snippets like the following:
--check if there are any records
Select count(*) INTO v_cnt FROM XXX WHERE XXXX=XXXX;
--if there are records
IF v_cnt > 0 THEN
--get the data of this records
SELECT a,b,c INTO v_a,v_b,v_c FROM XXX WHERE XXXX=XXXX;
END IF;
Now i want to solve this with one SQL-Statement.
BEGIN
SELECT a,b,c INTO v_a,v_b,v_c FROM XXX WHERE XXXX=XXXX;
--Catch the "No data found"-Exception
EXCEPTION WHEN OTHERS THEN
NULL;
END;
IF (??theglobalvariablethatisearch??) > 0 THEN
END IF;
Is there such a "global Variable" in Oracle SQL??
Thanks

Why not eliminate the IF altogether? If NO_DATA_FOUND isn't raised, the number of rows must be > 0
BEGIN
SELECT a,b,c
    INTO v_a,v_b,v_c
    FROM XXX
   WHERE XXXX=XXXX;
<<contents of the THEN clause of your IF statement>>
--Catch the "No data found"-Exception
EXCEPTION
WHEN OTHERS
THEN
    NULL;

Script to query / monitor logins to Servers

Not sure if I'm in the right forum, apologies if I'm not. Not sure where this should go ... anyway, is it possible to query username logins to Windows Server 2008?
Information needed:
1) Username
2) date / time login
3) date / time logoff
Preferably, a way to query multiple servers at one go into an Excel file or something. And not using some freeware or additional installs.
Thanks

You'll need to turn on some auditing. This one may help.

Query monitoring using AUDIT

Hi all,
DB version : 11.2.0
OS version : RHEL 5.5
I have enabled auditing at the database level. Can anyone let me know how could i find out which query was executed by the user 2 hours before. I am not sure how could i find the query using AUDIT. Just able to see all the trace files generated in AUDIT file destination.
Thanks in advance....
Regards,
Imran Khan

if AUDIT_TRAIL is DB ,use below query
COLUMN username FORMAT A10
COLUMN owner    FORMAT A10
COLUMN obj_name FORMAT A10
COLUMN extended_timestamp FORMAT A35
SELECT username,
       extended_timestamp,
       owner,
       obj_name,
       action_name
FROM   dba_audit_trail
WHERE owner = '&ENTER_USERNAME'
ORDER BY timestamp;if audit trail is XML,trybelow
COLUMN db_user       FORMAT A10
COLUMN object_schema FORMAT A10
COLUMN object_name   FORMAT A10
COLUMN extended_timestamp FORMAT A35
SELECT db_user,
       extended_timestamp,

Growing query size while appending last query.

Hi!
I've got few blocks on my ORACLE FORMS form. Blocks A and B are connected by the master-detail relation. I've got table of records from B and above the table I've got buttons which sort this table. It's done by setting order by clause and then calling EXECUTE_QUERY.
Before I call execute_query I want to rewrite last_query not to lose previously set filters. I know that last_query contains default_where so not to have it repeated many times in a query I replace default_query with last_query before execute_query and revert after it.
My case is like this:
     Block SPRAWY with item ID is master for block SPAWY_TYT with item ID_WNIOSKI.
     On block SPRAWY_TYT I've got 'default where' set to ID_WNIOSKI = :SPRAWY.ID.
     When I call my sort procedure (click button) I'm getting last_query's (from block SPRAWY_TYT) where clause like: "ID_WNIOSKI='9' AND (ID_WNIOSKI='9')".
     After next click last_query looks like: "ID_WNIOSKI='9' AND (ID_WNIOSKI='9') AND (ID_WNIOSKI='9')" and it's growing with each click.
Final question:
     Where this part "(ID_WNIOSKI='9')" comes from and how can I remove it from last_query (I mean universal solution not depending on particular item or relatioin name)?
Regards,
Artur

Hi, Amrit,
Do you just want 9 copies of the selected rows from mth_dim_hierarchy, each with all the columns the same except for level_num?
If so, cross-join mth_dim_hierarchy with a Counter Table , that is, any table (or, as in this case, result set) with 9 rows. For example:
WITH     cntr     AS
     SELECT     LEVEL     AS n
     FROM     dual
     CONNECT BY     LEVEL     <= 9
SELECT      c.n                         AS LEVEL_NUM
,     To_Date ('01-JAN-1900','DD-MON-YYYY')      AS EFFECTIVE_DATE
,     -99999                          AS LEVEL_KEY
,     'Unassigned'                     AS LEVEL_NAME
,     -99999                          AS PARENT_KEY
,     'Unassigned'                     AS PARENT_NAME
,     MDH.HIERARCHY_ID
FROM           MTH_DIM_HIERARCHY      MDH
CROSS JOIN     cntr               c
WHERE      MDH.CREATION_DATE      >= v_log_from_date
AND     MDH.DIMENSION_NAME      = 'EQUIPMENT'
I hope this answers your question.
If not, post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) for all the tables involved, and the results you want from that data.
In the case of a DML operation (such as MERGE) the sample data should show what the tables are like before the DML, and the results will be the contents of the changed table(s) after the DML.
Explain, using specific examples, how you get those results from that data.
Simplify the prole, if possible. If you can show what you need to do with 3 distinct values of level_num, don't post a problem with 9 distinct values.
Always say what version of Oracle you're using.
