Create table query taking too long..

Hello experts...
I am taking the backup of table A which consist of 135 million records...
for this am using below query..
create table tableA_bkup as select * from tableA;
it is taking more than hour..still running....
is there any other way to query fast....
thanks in advance....

CTAS is one of the fastest ways to do such a thing.
Remember you duplicate data. THis means if your table holds 50GB of data then it will have to copy those 50GB of data.
A different way could be to use EXPDP to create a backup dump file from this table data. However I'm not sure if there is a big performance difference.
Both versions could profit from parallel execution.

Query taking too long

I am running a fairly complex query with several table joins
and it is taking too long. What can I do to improve performance?
Thanks.
Frank

Dan's first suggestion is key - if you are doing multiple
table joins, you want to make sure your indexes are set up on your
tables correctly. If you have access to the database, this should
be your first step. Rationalize's stored procedure suggestion is
also a great idea (again, if you have access to create and manage
stored procedures on your DB).
Other than than, most databases usually have some sort of SQL
efficiency analysis tool. SQL server has one built into their Query
Analyzer tool. I would recommend using something like that to
streamline your SQL. Like Dan said, something as simple as the
order of elements in your where clause might make a big
difference.

Query taking too long a time

Query taking too long, yet cost is low

hi guys,
I am running a query on two databases that were created the same way and have the same data.
On one the cost is nearly a million, and it runs in a matter of a few seconds
On the other, the cost is 40000, and it doesn't finish executing
I have looked at the explain plan, and there is no cartesian merge join on the second query, yet it is taking so long. What can I do to investigate this?
thanks

Could you please post an properly formatted explain plan output using DBMS_XPLAN.DISPLAY including the "Predicate Information" section below the plan to provide more details regarding your statement. Please use the \[code\] and \[code\] tags to enhance readability of the output provided:
In SQL*Plus:
SET LINESIZE 130
EXPLAIN PLAN FOR <your statement>;
SELECT * FROM TABLE(DBMS_XPLAN.DISPLAY);Note that the package DBMS_XPLAN.DISPLAY is only available from 9i on.
In previous versions you could run the following in SQL*Plus (on the server) instead:
@?/rdbms/admin/utlxplsA different approach in SQL*Plus:
SET AUTOTRACE ON EXPLAIN
<run your statement>;will also show the execution plan.
In order to get a better understanding where your statement spends the time you might want to turn on SQL trace as described here:
[When your query takes too long|http://forums.oracle.com/forums/thread.jspa?threadID=501834]
and post the "tkprof" output here, too.

Query taking too long on Oracle9i

Hi All
I am running a query on our prod database (Oracle8i 8.1.7.4) and again running the same query on Test db (Oracle9i version 4). The query is taking too long(more then 10 min) in test db. Both the database are installed on the same machine IBM AIX V4 and table schema and data are same.
Any help would be appreciated.

To help us better understand the problem,
1) Could you post your execution plan on the two different databases?
2) Could you list indexes (if any, on these tables)?
3) Are any of the objects in the 'from list' a view?
If so, are you using a user defined function to create the view?
4) Why are you using the table 'cal_instance_relationship' twice in the 'from ' clause'?
5) Can't your query be the following?
SELECT f.person_id, f.course_cd, cv.responsible_org_unit_cd cowner, f.fee_cal_type Sem, f.fee_ci_sequence_number seq_no,

Loop with WMI Query taking too long, need to break out if time exceeds 5 min

I've written a script that will loop through a list of computers and run a WMI query using the Win32_Product class. I am pinging the host first to ensure its online which eliminates wasting time but the issue I'm facing is that some of the machines
are online but the WMI Query takes too long and holds up the script. I wanted to add a timeout to the WMI query so if a particular host will not respond to the query or gets stuck the loop will break out an go to the next computer object. I've added my code
below:
$Computers = @()
$computers += "BES10-BH"
$computers += "AUTSUP-VSUS"
$computers += "AppClus06-BH"
$computers += "Aut01-BH"
$computers += "AutLH-VSUS"
$computers += "AW-MGMT01-VSUS"
$computers += "BAMBOOAGT-VSUS"
## Loop through all computer objects found in $Computes Array
$JavaInfo = @()
FOREACH($Client in $Computers)
## Gather WMI installed Software info from each client queried
Clear-Host
Write-Host "Querying: $Client" -foregroundcolor "yellow"
$HostCount++
$Online = (test-connection -ComputerName ADRAP-VSUS -Count 1 -Quiet)
IF($Online -eq "True")
$ColItem = Get-WmiObject -Class Win32_Product -ComputerName $Client -ErrorAction SilentlyContinue | `
Where {(($_.name -match "Java") -and (!($_.name -match "Auto|Visual")))} | `
Select-Object Name,Version
FOREACH($Item in $ColItem)
## Write Host Name as variable
$HostNm = ($Client).ToUpper()
## Query Named Version of Java, if Java is not installed fill variable as "No Java Installed
$JavaVerName = $Item.name
IF([string]::IsNullOrEmpty($JavaVerName))
{$JavaVerName = "No Installed"}
## Query Version of Java, if Java is not installed fill variable as "No Java Installed
$JavaVer = $Item.Version
IF([string]::IsNullOrEmpty($JavaVer))
{$JavaVer = "Not Installed"}
## Create new object to organize Host,JavaName & Version
$JavaProp = New-Object -TypeName PSObject -Property @{
"HostName" = $HostNm
"JavaVerName" = $JavaVerName
"JavaVer" = $JavaVer
## Add new object data "JavaProp" from loop into array "JavaInfo"
$JavaInfo += $JavaProp
Else
{Write-Host "$Client didn't respond, Skipping..." -foregroundcolor "Red"}

Let me give you a bigger picture of the script. I've included the emailed table the script produces and the actual script. While running the script certain hosts get hung up when running the WMI query which causes the script to never complete. From one of
the posts I was able to use the Get-WmiCustom function to add a timeout 0f 15 seconds and then the script will continue if it is stuck. The problem is when a host is skipped I am not aware of it because my script is not reporting the server that timed out.
If you look at ZLBH02-VSUS highlighted in the report you can see that its reporting not installed when it should say something to the effect query hung.
How can I add a variable in the function that will be available outside the function that I can key off of to differentiate between a host that does not have the software installed and one that failed to query?

Oracle - Query taking too long (Materialized view)

Hi,
I am extracting billing informaiton and storing in 3 different tables... in order to show total billing (80 to 90 columns, 1 million rows per month), I've used a materialized view... I do not have indexes on 3 billing tables - do have 3 indexes on Materialized view...
at the moment it's taking too long to query the data (running a query via toad fails and shows "Out of Memory" error message; runing a query via APEX though is providing results but taking way too long)...
Please advice how to make the query efficient...

tparvaiz,
Is it possible when building your materialized view to summarize and consolidate the data?
Out of a million rows, what would your typical user do with that amount data if they could retrieve it readily? The answer to this question may indicate if and how to summarize the data within the materialized view.

Query taking too long to finish

Hi,
I'm running a query which is
Delete from msg where ID IN (select ID from deletedtrans );
It's taking too long to complete, it has been running for 24 hours already and not completed executing the query, I cancelled the query. I don't understand why it's taking too long, does anyone have any idea? I feel that this query should not take too long to complete

That seems to be too small piece of information to comment anything.
1. How many records are there in "deletedtrans" table ?
2. How many records from "msg" table are expected to be deleted ?
3. Are statistics up-to-date on "msg" and "deletedtrans" tables ?
4. Is "ID" column defined as NULL or NOT NULL in both "msg" and "deletedtrans" tables ? (Not sure whether this will cause any problem, but...)
5. Is this statement being executed when other users/applications are accessing/updating "msg" table ?

Query taking too long to execute

Hi All,
I have just moved a cube from DEV to Q and loaded the data(using INIT). I have created a query to test the data. When I execute the query, the initial result is showing up quickly but when I drill down using one char, say CHAR ABC, it is taking a lot time(I am waiting from last 25 min to see the result but it is still running). The same query is not taking any time when run in T. What could be the problem. This query is my first query in Q.
Any suggestions would be highly appreciated.
Best Rgds,
James.

GO to RSRV and you will see a an option " All combined tests.
IN that, you will see " Check data for master data". Double click that and enter your CHAR* and run the test.
Next under transaction data " run each of the tests" for the ODS / Cube that you run the report from.
These tests usually will point to inconsistency. You may also want to look the design of cube / ODS. In ODS, you may have to check the key fields.

Partition Table Query taking Too Much Time

I have created partition table and Created local partition index on a column whose datatype is DATE.
Now when I Query table and use index column in the where clause It is scaning all the table (Full scan) . The quey is :
Select * From mytable
where to_char(transaction_date, 'DD-MON-YY') = '01-Aug-07';
I have to use to_char function not to_date due to Front end application problem.

Before we go too far with this, if you manually query with TO_DATE on the variable instead of TO_CHAR on the column, does the query actually use the index?
The TO_CHAR on the column will definitely stop Oracle from using any index on the column. If the query will use the index if you TO_DATE the variable, as I see it, you have three options. First, fix the application problem that won't let you use TO_DATE from the application. Second, change the application to call a function returning a ref cursor, get the date string as a parameter to the function, and do the TO_DATE in the function.
Third, you could consider creating a function-based index on TO_CHAR(transaction_date, 'dd-Mon-yy'). This would be the least desirable option, particularly if you would also be selecting records based on a range of transaction_dates, since it loses a lot of information that the optimizer could use in devising an efficient query plan. It could also change your results for a range scan.

Sql query taking too long to run

I am not sure what to do. My app takes two long to run and the reason is right in front of me, but again, I don't know what to do or where to go. (VB.Net VS 2005)
The main part of my query takes about 15 to 20 seconds to run. When I tack on this other part it slows the response to over 2 minutes.
Even running this other part alone takes 2+ minutes. The query as two sum functions. Is it possible, some how, that this query can run building it's results into another table and then I use this new table with the results all ready to go and join into the first part of the main query?
I am using oracle 9i with a Sql Developer. Which I am new to. Below is the culprit: Thanks

SQL Query taking too long

Hello there,
Can someone please help me:
I have this SQL query that is taking days to complete, and they say when it runs on the former DB version 8 it used to run for 1 hour but now we're using 10g ... it's taking days ... any help with that please?

A few comments:
1. Please re-edit your post and add the "Predicate Information" section below the plan, so that the filter and access predicates can be seen. They're quite helpful to understand the execution plan better.
2. You're using bind variables, therefore the EXPLAIN PLAN output is only of limited use, since EXPLAIN PLAN doesn't perform "bind variable peeking". With "bind variable peeking" the optimizer peeks at the actual values passed when determining the execution plan. If you have a histogram generated on PS_JRNL_LN.JOURNAL_ID (check DBA/ALL/USER_TAB_COLUMNS.HISTOGRAM) or the values used are "out-of-range" (less or greater than recorded min and max value of column) then you might get different execution plans depending on the actual values passed.
3. You can get the actual execution plan(s) from the shared pool by obtaining the SQL_ID of the statement (e.g. check V$SESSION) and use the DBMS_XPLAN.DISPLAY_CURSOR function for this SQL_ID
4. The optimizer estimates that out of the 11 million rows of PS_JRNL_LN more or less no rows corresponds to this predicate:
A.JOURNAL_ID = :1
AND A.JRNL_LINE_STATUS = '1'
Since for the unknown bind variable a hard coded default selectivity of 5% is used which corresponds to a cardinality approx. 550,000 rows, the JRNL_LINE_STATUS = '1' predicate seems to be quite selective.
Is this estimate in the right ballpark or way off?
Due to this estimate the optimizer uses a cartesian join which could generate a very large intermediate set if the estimate is way off, e.g. if 1,000 rows are returned instead of 0 the cartesian join will already generate 1,000 * 116,000 => 116,000,000 rows.
This row source will then be used as driving source of a nested loop which means that many times the index and table lookup to PS_BI_ACCT_ENTRY will be performed.

SQL query taking too long to process

dear guys. i have this one problem, where the sql statements really took very long time to be processed. It took more than 1 minute, depending on the total data in the table. I guest this have to do with the 'count' statements. here is the code:
$sql = "SELECT company,theID,abbs,A as Active,N as Nonactive,(A+N) as Total
FROM(
select distinct D.nama As company, C.domID As theID, D.abbrew As abbs,
count(distinct case when B.ids is NOT NULL THEN A.dauserid END) As A,
count(distinct case when B.ids is NULL THEN A.dauserid END) As N
FROM
tableuser A LEFT OUTER JOIN tabletranscript B on (A.dauserid=B.dauserid)
INNER JOIN thedommember C ON(C.entitybuktiID=1 AND C.mypriority=1 AND
C.entitybuktiID=A.dauserid)
INNER JOIN mydomain D ON (C.domID=".$getID.")
GROUP BY D.nama, C.domID, D.abbrew
ORDER BY company
Hope any of you can simplify this statements into a query that doesnt take ages to be processed.

What yours oracle version?
Did you gather stats?
stats are used by the optimizer for a better assessment query plan,if yours stats is stale then query plan behave inadvertly
Can you paste yours this specific query tracer file by using tkprof here with wait events?
Can you avoid DISTINCT clause from urs sequel,cause DISTINCT will always require a sort and sorting slows performance?
More or less unless if you cant go through from above statment its hard to find whats the real issue with this sequel.
