Select * query is slow on one particular table

Hi ,
I am using forms and reports of AppServer 10g,one particular form accesing one table ...The select * from statement on that table is slow.Any amendmends to be taken care of at the tablespace level??
Help needed urgent...
Regards,
Ashlee

Hi,
This is a general type of question. please be specific. Golden Thumb rule is that don't use '*", instead use the column names. Analyze the table and take a execution plan and check for index usage .
Please give the problem statement also so that we can help you.

Issue in data replication for one particular table

Hi,
We have implemented streams in out test environment and testing the business functionalities. We have an issue in data replication for only one custom table all other tables data replications are proper no issue. When we do 100 rows update data replication is not happening for that particular table.
Issue to simulate
Update one row -- Replication successful.
100 rows update -- After 3-4 hrs nothing happened.
Please let me know did any of you have come across similar issue.
Thanks,
Anand

Extreme slowness on apply site are usually due to lock, library cache locks or too big segments in streams technical tables left after a failure during heavy insert. these tables are scanned with full table scan and scanning hundreds of time empty millions of empty blocks result in a very big loss of performance, but not in the extend your are describing. In your case it sound more like a form of lock.
We need more info on this table : Lob segments? tablespace in ASSM?
If the table is partitioned and do you have a job that perform drop partitions? most interesting is what are the system waits nd above all the apply server sessions waits. given the time frame, I would more looks after a lock or an library cache lock due to a drop partitions or concurrent updates. When you are performing the update, you may query 'DBA_DDL_LOCKS', 'DBA_KGLLOCK' and 'DBA_LOCK_INTERNAL' to check that you are not taken in a library cache lock.

Select query performance improvement - Index on EDIDC table

Hi Experts,
I have a scenario where in I have to select data from the table EDIDC. The select query being used is given below.
SELECT docnum
          direct
          mestyp
          mescod
          rcvprn
          sndprn
          upddat
          updtim
INTO CORRESPONDING FIELDS OF TABLE t_edidc
FROM edidc
FOR ALL ENTRIES IN t_error_idoc
WHERE
upddat GE gv_date1 AND
upddat LE gv_date2 AND
updtim GE p_time AND
status EQ t_error_idoc-status.
As the volume of the data is very high, our client requested to put up some index or use an existing one to improve the performance of the data selection query.
Question:
4.    How do we identify the index to be used.
5.    On which fields should the indexing be done to improve the performance (if available indexes donu2019t cater to our case).
6.    What will be the impact on the table performance if we create a new index.
Regards ,
Raghav

Question:
1.    How do we identify the index to be used.
Generally the index is automatically selected by SAP (DB Optimizer ) ( You can still mention the index name in your select query by changing the syntax)
For your select Query the second Index will be called automatically by the Optimizer, ( Because the select query has u2018Updatu2019 , u2018uptimu2019 in the sequence before the u2018statusu2019 ) .
2.    On which fields should the indexing be done to improve the performance (if available indexes donu2019t cater to our case).
(Create a new Index with MANDT and the 4 fields which are in the where clause in sequence )
3.    What will be the impact on the table performance if we create a new index.
( Since the index which will be newly created is only the 4th index for the table, there shouldnu2019t be any side affects)
After creation of index , Check the change in performance of the current program and also some other programs which are having the select queries on EDIDC ( Various types of where clauses preferably ) to verify that the newly created index is not having the negative impact on the performance. Additionally, if possible , check if you can avoid into corresponding fields .

Sinlge select query in diff schemas for same table(Indentical Structure)

Scenario :
Table XYZ is created in Schema A
After an year, the old data from the previous year would be moved to different schema. However in the other schema the same table name would be used.
For eg
Schema A contains table XYZ with data of 2012 yr
Schema B contains table XYZ with data of 2011 yr
Table XYZ in both the schemas have identical structure.
So can we fire a single select query to read the data from both the tables in effective way.
Eg select * from XYZ where date range between 15-Oct-2011 to 15-Mar-2012.
However the data resides in 2 different schema altogether.
Creating an view is an option.
But my problem, there is ORM layer(either Hibernate or Eclipse Top Link) between the application and the database.
So the queries would be formed by the ORM layer and are not hand generated.
So i cannot use view.
So is there any option that would allow me to use single query on different schema's ?

However the data resides in 2 different schema altogether.You can do a UNION, so the data from the two years appears together. The number of actual tables may make the query slower, but it won;t change the results.
Given that you have 2 tables, the fact that they are in different schemas doesn't matter. Just make sure the user running the query has SELECT privileges on both of them.
Creating an view is an option.Is it? You seem to say it is not, below.
But my problem, there is ORM layer(either Hibernate or Eclipse Top Link) between the application and the database.

So is there any option that would allow me to use single query on different schema's ?Anything that you can do with a view, you can do with sub-queries. A view is merely a convenience; it just saves a sub-query, so you don't have to re-code it every time you use it. Assuming you have privilges to query the base tables, you can always avoid using a view by repeating the query that defines the view in your own query. It will not be any slower

SELECT query very slow, need suggestion.

Dear all,
Below stmt was coded in my report program.
It was taking around 14 seconds in development system. The days in s_datum was just 1 or 2 days max.
But when the same was transferred to test system, it is taking almost 10 minutes, though it we gave just 1 day.
SELECT * FROM likp INTO TABLE i_likp
        WHERE erdat IN s_datum AND wadat_ist > '00000000'
          AND lfart <> 'EL'
          AND vstel not in s_vstel.
Some of you might suggest to make SELECT query with only s_datum, but i tried it in dev system, it was taking almost 22 secs with only s_datum. I thought it could be more worse in test system so, did not move that idea.
Can some one please suggest me why it is happening so.

Hi,
The difference, as I suppose you know, happens because LIKP probably has much more records in production than in the development system.
You must think what is selective in your WHERE clause:
- erdat in s_datum is selective if you are are only using one day
- wadat_ist GE '00000000' is not selective (all deliveries with goods issue fulfill that condition)
- lfart NE 'EL' probably is not selective
- vsten not in s_vstel probably is not selective
So in the end only erdat is selective. There is no index in LIKP by ERDAT, so if you really want to make it faster you would need an index by ERDAT.
Still, if you are only making one SELECT (not inside a loop) I wouldn't expect that to take more than 10 minutes.
I would measure the program with SE30 to make sure it is really the SELECT that is taking so much time (post here the results), and if it really is the select post here the explain plan.
By the way, if you need to know all goods issues for the last day I would use change pointers instead.
Hope this helps,
Rui Dantas

You can also check global cache statistics. Run this before and after your query :
select name, value from v$mystat s, v$statname n where s.statistic#=n.statistic# and name like '%blocks received';

Query not executing for one particular value

Hi
I have query on multi provider. and this multi provider is combination of Info objects only but not any ODS or cubes. I have one key figure in this multi provider.while executing the query i need to give input for variabl which has 7 different values. Query is executing fine for 6 values but not for one particular value.
query executed in listcube transaction and it is executed fine here for the same selection. then what might be the reason?
Please advise as soon as possible.
Thanks

Hi Kiran,
are you maintaining any filters in the query? or is there any logic in the exit for this variable.

Creating an view is an option.

So i cannot use view.
So is there any option that would allow me to use single query on different schema's ?

Dynamic Select query is failing with error "Invalid Table Name"

OPEN rc FOR 'SELECT count(*) from :s' USING tab_name;
fetch rc into rec_count;
CLOSE rc;
my requirement is to build dynamic select query to retrieve the total count of rows in each table ( variable tab_name contains the table_name )
But I am getting stuck by this errror, not sure if there is any alternative !
ORA-00903: invalid table name
ORA-06512: at line 43

OPEN rc FOR 'SELECT count(*) from '||tab_name;
fetch rc into rec_count;
CLOSE rc;
-- This will work
1. Create a sql statement.
2. Open ref cursor for that statement.

Select query for sales order for particular customer oder text and storage

Hi All,
I am trying to retriev customer order text and customer storage bin from the following select query, but it's giving huge number of records, I want to restrict the number of records.
Select customer order text, customer storage bin
                   Select STXHTDOBJECT, STXHTDID
                   Where TDOBJECT = VBBP
                          TDID = Y001
                          TDID = Y007
Please let me know how to restirct the number of records.
Thanks,
Ranjan

Try using the FM 'READ_TEXT'.
NAME will be the order number concatenated with the item number.
And you have the ID and OBJECT. You may also need to use the LANGUAGE.

Nested Tables select query soooooo slow

I know that varrays are supposed to be used for small arrays. But, we are comparing nested tables to varrays and two table joins. Nested table query is unimaginably ,unacceptably slow.
Is there anybody else out there who experienced the same thing. Are there ways to speed up the select queries.(besides indexes)

If you try to use nested sql statement. Please be sure to setup the index to some specific tables inside oracle
Doing this will speed up your performance about 5 ~ 9 times original.

Query running slow in one node

Hi All,
We are running 4-node Oracle 10g RAC (linux 64-bit). The query is running fast in one node, but the same query is running very slow in the other node. And sometimes, we see pin S wait on X wait event in top 5 events.
Has anyone faced this kind of situation before ?
Thanks,

Hi,
Execute your query on node where query is running very slow. Get SID and execute query above to see what is event of waiting.

Delete query is slow in one schema.

Hi All,
I have two schemas in a database PRDPUB and TOOLSERVER . In both the schemas i have a table BP_USER_PROFILE containg same amount of data , indexes and constrains. I am using one delete query to delete 26000 records from both the table , but in PRDPUB schema it is hanging but in TOOLSERVER schema it is running fine.When i tried to delete 100 records using the same query in PRDPUB schema it is taking 44 second nad 13 milisecond in TOOLSERVER.
when i generated the exution plan it is very much same .But when i see the trace file i see in PRDPUB schema it is accessing the disk and doing parsing and execution 2 times , while in TOOLSERVER schema it is deleting in memory and parsing and executing once.
For your reference i am attching the expalin plan and trace file output. Please help me out to resolve the issue.
explain plan for delete from bp_user_profile where id_user in (select id_user from (SELECT * FROM bp_user_profile WHERE
id_home_category=5005 AND DT_USER_LAST_UPDATED <'01-DEC-09' AND ID_USER_STATUS_ACTIVE ='DELETED_BY_ADMIN'

Hi,
is your delete correct?
delete from toolserver.bp_user_profile where id_user in (select id_user from (SELECT * FROM toolserver.bp_user_profile WHERE
id_home_category=:"SYS_B_0" AND DT_USER_LAST_UPDATED <:"SYS_B_1" AND ID_USER_STATUS_ACTIVE =:"SYS_B_2"
OR ID_USER_STATUS_ACTIVE =:"SYS_B_3") where rownum<=:"SYS_B_4")There is a suspected OR in the where clause, I expect you have to check both statusses with the date and home category, so I think your query should be (add parenthesisses around the two statusses):
delete from toolserver.bp_user_profile where id_user in (select id_user from (SELECT * FROM toolserver.bp_user_profile WHERE
id_home_category=:"SYS_B_0" AND DT_USER_LAST_UPDATED <:"SYS_B_1"
AND
( -- added
ID_USER_STATUS_ACTIVE =:"SYS_B_2"
OR ID_USER_STATUS_ACTIVE =:"SYS_B_3"
) -- added
) where rownum<=:"SYS_B_4")Further is the content the same, if these are different, you could also have differences in execution time.

How to use dynamic select query which queries from 3 different table.

Hi All,
I am new to Toplink, i would like to use a named query to select some of the columns from 3 different tables with dynamic where clause.
I have used the following lines. Please tell me how to get code for the dynamic where clause.
First try :
Vector objPersons = (Vector)session.executeQuery("findPersonByGlobalID",Person.class,vQueryArguments);
The above method is not returning the vector or collection.
Second Try:
ReadAllQuery query = new ReadAllQuery(Person.class);
query.useCollectionClass(LinkedList.class);
LinkedList person = (LinkedList) session.executeQuery(query);
The second try is returning the collection but, this fetches all the record from the table.
1. How to query for range of records?
2. How to query from multiple tables for some range. How to use dynamic range values ?
Please reply with your answers or some pointers would help.
Thanks and Regards,
Vijay.B

Hi,
Did you try using a SQLCall ? It might be able to satisfy you requirements .. :-
Employee employee = (Employee) session.executeSelectingCall(
new SQLCall("SELECT * FROM EMPLOYEE WHERE EMP_ID = 44")
);You can get more information here :-
