9i index query problem SLOW

I have recently upgraded to the about 9i and have experienced poor performance on many queries. In 8i selecting the max(a_date) from a table took milliseconds. In 9i the same query never seems to return. The explain plan also does not seem to accurately reflect the behavior performed by the query.
An related experiences would be welcome

Not much to go on. An open door, just in case you hadn't thought of it yourself:
Perhaps you are using cost based optimization in 9i where as in 8i you were using rule based. Take a look at the init.ora and see parameter OPTIMIZER_MODE is set the same in 9i as in 8i. Typically, if you go from RULE to COST but don't ANALYZE your objects, performance problems like these could happen.
Just a thought,
L.

Bitmap index query is slow

All,
I have Dataware house environment. I have bitmap index in all the dimension id's in fact table. Here is the query. This query took 10 min... It is not affordable time.
Any help?..
SELECT count(*)

WHERE a.quote_dim_sid = b.quote_dim_sid
AND b.order_dim_sid = c.order_dim_sid
We have bit map index on quote_dim_sid & order_dim_sid .

Update query is slow with merge replication

Hello friend,
I have a database with enabling merge replication.
Then the problem is update query is taking more time.
But when I disable the merge triggers then it'll update quickly.
I really appreciate your
quick response.
Thanks.

Hi Manjula,
According to your description, the update query is slow after configuring merge replication. There are some proposals for you troubleshooting this issue as follows.
1. Perform regular index maintenance, update statistics, re-index, on the following Replication system tables.
    •MSmerge_contents
    •MSmerge_genhistory
    •MSmerge_tombstone
    •MSmerge_current_partition_mappings
    •MSmerge_past_partition_mappings
2. Make sure that your tables involved in the query have suitable indexes. Also do the re-indexing and update the statistics for these tables. Additionally, you can use
Database Engine Tuning Advisor to tune databases for better query performance.
Here are some related articles for your reference.

Query is slow on staging

Hi Friends ,
i am using 11.2.0.3.0 oracle db . We have a query which is running smoothly on Live and the same query runs slow on staging environment . The data is pulled from Live to staging using Golden Gate and not all columns are refreshed .
Can you please help me tune this query or let me know what best can be done for this query to run like Live environment .
Regards,
DBApps

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.

Query is slow

SELECT SUM(A.NO_MONTH_CONSUMPTION),SUM(A.BASE_CONSUMPTION),SUM(A.CURRENT_DOC_AMT),SUM(A.CUR_TAX),SUM(B.CURRENT_DOC_AMT)

the above view "VW_x" has around 40 million records from two tables and avg_ind column has only 0 and 2 values. I created a functional index on both table something like create index on x1 nvl(avg,0)

Indices configuration for XML document analysis (indexing time problems)

Hi all,
I'm currently developing a tool for XML Document analysis using XQuery. We have a need to analyse the content of a large CMS dump, so I am adding all documents to a berkeley DB xml to be able to run xqueries against it.
In my last run I've been running to indexing speed problems, with single documents (typically 10-20 K in size) taking around 20 sec to be added to the database after 6000 documents (I've got around 20000 in total). The time needed for adding docs to the database drops with the number of documents.
I suspect my index configuration to be the reason for this performance drop. Indeed, I've been very generous with indexes, as we have to analyse the data and don't know the structure in advance.
Currently my index configuration includes:
- 2 default indicess: edge-element-presence-none and edge-attribute-presence-none to be able to speed up every possible xquery to analyse data patterns: ex. collection()//table//p[contains(.,'help')]
- 8 edge-attribute-substring-string indices on attributes we use often (id, value, name, ...)
- 1 edge-element-substring-string index on the root element of the xml documents to be able to speed up document searches: ex. collection()//page[contains(.,'help')]
So here my questions:
- Are there any possible performance optimisations in Database config (not index config)? I only set the following:
setTransactional(false);
envConf.setCacheSize(1024*64);
envConf.setCacheMax(1024*256);
- How can I test various index configuration on the fly? Are there any db tools that allow to set/remove indexes?
- Is my index config suspect? ;-)
Greetings,
Nils

Hi Nils,
The edge-element-substring-string index on the document element is almost certainly the cause of the slow document inserts - that's really not a good idea. Substring indexes are used to optimize "=", contains(), starts-with() and ends-with() when they are applied to the named element that has the substring index, so I don't think that index will do what you want it to.

Why is the query so slow?

Hi,
I've got a query running fast (3 sec.)
If I try to execute it on test enviroment, it takes about 2 minutes (!)
I see in both enviroments the explain plan is the same and so are the indexes used. I've also tried to rebuild the indexes and the tables that looked quite fragmented in test, but the result is always the same. Could it be that our test enviroment is slower and with lower performances? What else could I check? (Oracle Vers. is 8.1.7)
Thanks!

Query very slow!

I have Oracle 9i and SUN OS 5.8
I have a Java application that have a query to the Customer table. This table has 2.000.000 of records and I have to show its in pages (20 record each page)
The user query for example the Customer that the Last Name begin with O. Then the application shows the first 20 records with this condition and order by Name.
Then I have to create 2 querys
1)
SELECT id_customer,Name
FROM Customers
WHERE Name like 'O%'
ORDER BY id_customer
But when I proved this query in TOAD it take long to do it (the time consuming was 15 minutes)
I have the index in the NAME field!!
Besides, if the user want to go to the second page the query is executed again. (The java programmers said me that)
What is your recommendation to optimize it????? I need to obtain the information in
few seconds.
2)
SELECT count(*) FROM Customers WHERE NAME like 'O%'
I have to do this query because I need to known How many pages (20 records) I need to show.
Example with 5000 records I have to have 250 pages.
But when I proved this query in TOAD it take long to do it (the time consuming was 30 seconds)
What is your recommendation to optimize it????? I need to obtain the information in
few seconds.
Thanks in advance!

This appears to be a dulpicate of a post in the Query very slow! forum.
Claudio, since the same folks tend to read both forums, it is generally preferred that you post questions in only one forum. That way, multiple people don't spend time writing generally equivalent replies.

Why index creation is slower on the new server?

Hi there,
Here is a bit of background/env info:
Existing prod server (physical): Oracle 10gR2 10.2.0.5.8 on ASM
RAM: 96GB
CPUs: 8
RHEL 5.8 64bit
Database size around 2TB
New server:
VMWare VM with Oracle 10gR2 10.2.0.5.8 on ASM
RAM 128GB
vCPUs: 16
RHEL 5.8 64bit
Copy of prod DB (from above server) - all init param are the same
I noticed that Index creation is slower on this server. I ran following query:
SELECT name c1, cnt c2, DECODE (total, 0, 0, ROUND (cnt * 100 / total)) c3
FROM (SELECT name, VALUE cnt, (SUM (VALUE) OVER ()) total
FROM v$sysstat
WHERE name LIKE 'workarea exec%')
C1
C2
C3
workarea executions - optimal
100427285
100
workarea executions - onepass
2427
0
workarea executions - multipass
0
0
Following bitmap index takes around 40mins in prod server while it takes around 2Hrs on the VM.
CREATE BITMAP INDEX MY_IDX ON
MY_HIST(PROD_YN) TABLESPACE TS_IDX PCTFREE 10
STORAGE(INITIAL 12582912 NEXT 12582912 PCTINCREASE 0 ) NOLOGGING
This index is created during a batch-process and the dev team is complaining of slowness of the batch on new server. I have found this one statement responsible for some of the grief. There may be more and I am investigating.
I know that adding "parallel" option may speedup but I want find out why is it slow on the new server.
I tried creating a simple index on a large table and it took 2min in prod and 3.5min on this VM. So I guess index creation is slower on this VM in general. DMLs (select/insert/delete/update) seem to work with better elapsed time.
Any clues what might be causing this slowness in index creation?
Best regards

I have been told that the SAN in use by the VM has capacity of 10K IOPS. Not sure of this info helps. I don't know more than this about the storage.
What else do I need to find out? Please let me know - I'll check with my Sys Admin and update the thread.
Best regards

Non - indexed query's (9I)

Hello everbody,
How do I retrieve all the NON indexed query's used in the database? I want to find out which ones I need to optimize.
thanks John

Hello
That's not as easy as it sounds. Creating indexes for every query that does not use one could very easily cause more problems than it fixes. Full table scans are not evil, they are often the fastest way to access a relatively large portion of data in a table.
If you have issues with performance in your database you need to know exactly what they are, and you can get a very good idea by using statspack.
http://download-west.oracle.com/docs/cd/B10501_01/server.920/a96533/statspac.htm#21793
Once you have the right metrics, you can make an informed decision as to what the correct course of action is to solve any performance problems you are having. Without these metrics, you are groping in the dark.

Query Designer slows down after working some time with it

Hi all,
the new BEx Query Designer slows down when working some time with it. The longer it remains open, the slower it gets. Especially formula editing slows down extremely.
Did anyone of you encounter the same problem? Do you have an idea, how to fix this. To me it seems as if the Designer allocates more and more RAM and does not free that up.
My version: BI AddOn 7.X, Support Package 13, Revision 467
Kind regards,
Philipp

I have seen a similar problem on one of my devices, the 'Samsung A-920'. Every time the system would pop up the 'Will you allow Network Access' screen , the imput from all keypresses from then on would be strangely delayed. It looked like the problem was connected with the switching from my app and the system dialog form. I tried for many many long hours / days to fix this, but just ended up hacking my phone to remove the security questions. After removing the security questions my problem went away.
I don't know if it's an option in your application, but is it possible to do everything using just one Canvas, and not switch between displayables? You may want to do an experiment using a single displayable Canvas, and just change how it draws. I know this will make user input much more complicated, but you may be able to avoid the input delays.
In my case, I think the device wasn't properly releasing / un-registering the input handling from the previous dialogs, so all keypresses still went through the non-current network-security dialog before reaching my app.

Query performance slow

Hi Experts,
Please clarify my doubts.
1. How can we know the particular query performance slow in all?
2. How can we define a cell in BEx?
3. Info cube is info provider, Info Object is not Info Provider why?
Thanks in advance

Hi,
1. How can we know the particular query performance slow in all?
   When you run the query it's take more time we know that query is taken more if where that query is taking more time you can collect the statics.
   like Selct your cube and set BI statics check box after that it will give the all statics data regarding your query.
DB time (Data based time),Frent end Time (Query), Agrreation time like etc. based on that we go for the perfomance aggreations, compresion, indexes etc.
2. How can we define a cell in BEx?
   In Your Bex query your using two structures it's enabled. If you want create the different formulate by row wise you go for this.
3. Info cube is info provider, Info Object is not Info Provider why?
    Info object also info provider,
    when your info object also you can convert into info provider using " Convert as data target".
Thanks and Regards,
Venkat.

In the above procedure if i substitute the values with hard coded values i.e. AR_orgid = 123 & pcountry = 'Austria' then it runs faster.
Please let me know why it is so ?
Thanks in advance.

Query is slow to reutn result...

The following query is slow, I have index on tzk, and the event_dtg column is date column and allow null value.
abc_zone have > 60 millions records. Statistics on table and index is current.
Any idea how to improve the query performance?
select count (*) tz6
from abc_zone
where tzk =6
and event_dtg > to_date('09/05/2009 01:00:00' , 'MM/DD/YYYY HH24:MI:SS')
and event_dtg < to_date('04/04/2010 00:00:00' , 'MM/DD/YYYY HH24:MI:SS')
Oracle 10.2.0.3 on AIX
Thanks in advance.

sorry, I do have index on event_dtg...
here is the EP:
| Id | Operation | Name | Rows | Bytes | Cost (%CPU)| Time |
| 0 | SELECT STATEMENT | | 1 | 19 | 148 (0)| 00:00:01 |
| 1 | SORT AGGREGATE | | 1 | 19 | | |
| 2 | TABLE ACCESS BY INDEX ROWID| ABC_ZONE | 16 | 304 | 148 (0)| 00:00:01 |
| 3 | INDEX RANGE SCAN | ABC_ZONE_EVENT_DTG | 3439 | | 1 (0)| 00:00:01 |
Query Block Name / Object Alias (identified by operation id):
1 - SEL$1
2 - SEL$1 / ABC_ZONE@SEL$1
3 - SEL$1 / ABC_ZONE@SEL$1
17 rows selected.
I suspect there is some kind of conversion (date to timestamp) that is costly.
Thanks.
