Well, if you've ever looked at the source for DBA_TAB_STATISTICS you will understand why it's not a great candidate to query frequently, like in an exists look up :)
This takes up a little more code, but i'd wager it finishes a bit sooner.

Query takes 14 hours to complete - kindly help
I'm using Oracle9207 32bit on windows server 2003.
I executed the following query and it takes 14 hours to complete. I don't understand why it takes too long, the database is in archivelog mode and it is not running any other queries. I even specified nologging and the parallel option. And before performing the operation I even "alter table move..." the incmsg table.
The incmsg table contains around 70Million rows.
create table "ECI"."outactions_temp" tablespace USERS nologging parallel as select * FROM "ECI"."outactions" WHERE "ECI"."outactions"."incmsgserno" IN (select "ECI"."incmsg"."serno" from "ECI"."incmsg" where "ECI"."incmsg"."applicationserno" = 2 and "ECI"."incmsg"."timestamp" between to_date('01-MAY-2007', 'DD Mon YYYY') and to_date('21-SEP-2007', 'DD Mon YYYY'));
The execution plan is as follows:

Domain index query takes 12 hours to execute
Hi Friends,
My query which uses domain index takes 12 hours to execute. Can you please help me tuning this query?
select /*+ NO_UNNEST ORDERED index_ffs(Term idx_recanon_term_ysm1) parallel_index(Term, idx_recanon_term_ysm1, 8) */ term.rowid
from cmpgn.recanon_search_terms,cmpgn.recanon_term_ysm Term
where cmpgn.recanon_search_terms.search_type=3 and
contains(Term.RAW_TERM_TEXT,cmpgn.recanon_search_terms.search_text) > 0 and
Term.pod_id=11
Thanks in advance.
Regards
BalaFirst your driving table is recanon_search_terms to get the required search terms, then use them to query Oracle Text. What you are trying to do is to get a subset of table term first and than run every individual row of table term against the search terms. This approach will take a very long time.
Not sure what you want to do, but it looks something I have been working on previously. As far I can see there is a table with controlled terms which are matched against other raw terms in a text document using Oracle Text. The issue is that you do a join in the contains clause without knowing the number of query expressions formed. It can be that 7 thousand individual queries run at once, than use indexes of the other predicates, do some sorting, etc. which would explain the long time needed. It will probably run out of memory causing all sorts of issues.
As a quick fix try first following statement without hints.
Tell us how many rows you get, the distinct counts for pod_id and search_type and how long it takes.
CREATE TABLE test_table AS
select term.pod_id pod_id, cmpgn.recanon_search_terms.search_type search_type, term_primary_key, ....
from cmpgn.recanon_search_terms,cmpgn.recanon_term_ysm Term
where contains(Term.RAW_TERM_TEXT,cmpgn.recanon_search_terms.search_text) > 0
Create index test_idx on test_table(pod_id, search_type) and use test_table instead to get the results, just by providing pod_id and search_type without the join in the contains clause.
SELECT ..
FROM test_table
WHERE pod_id = X
AND search_type = Y
Maybe this approach is sufficient for your purpose. For sure, it will give you instant results. In that case a materialized view instead of the table could work for maintenance reasons; I had some issues with materialized views for above scenario.
However check very carefully the results. I would have some doubts that all rows in search_text form a valid query expression for Oracle Text. If search_text has just single tokens or phrases wrapping curly brackets around will probably resolve the issue.
Think about to form one query expression through a function call instead of a table join inside the contains clause. Sometimes to run a set of individual queries are faster than one big query.
select term.rowid --, form_query_exrpession(3) query_exrpession
from cmpgn.recanon_term_ysm Term
where contains(Term.RAW_TERM_TEXT, form_query_exrpession(3)) > 0
The above function will form one valid Oracle Text query expression by using the table recanon_search_terms inside the function. This approach normally helps, at least in debugging and fine-tuning. Avoid using bind variables first in order to identify highly skewed distribution of search_type.
The other performance issue is the additional predicate of pod_id = X, here the suggestion from radord works very well. If you want to get your hands dirty have a look at user_datastore in the Oracle Text documentation, this will give you all the freedom you want. -
SQL Query takes 7 hours after upgrade to 10g
the following query executes in under a minute in 9i, however once upgraded to 10g it takes 7 hours. The query is designed to select the data row with the max date value for the selected criteria (there are multiple rows that match the below criteria with different dates)
I have tested in a lower environment the setting of "_optimizer_cost_based_transformation"=off and this corrects the problem. I do not feel comfortable setting this parameter session or system wide to provide a solution

I do not feel comfortable setting this parameter session or system wide to provide a solutionIf you're sure that the "lower" environment reproduces the same issue, and not due to some other differences (different statistics, parameters etc.), then you could share the two different execution plans generated via DBMS_XPLAN.DISPLAY having the cost based transformations turned on and off. Make sure you use the \ tags before and after the plan output to format it in fixed font. You can use the "Quote" button in the message editor to see how to use the tag.
Furthermore a optimizer trace (10053) might reveal why the cost based transformations lead to such an result.

HOW TO: Post a SQL statement tuning request - template posting -
Select count(*) where exists (takes 5 hours).
Hello Gurus,
I have two databases on two servers, I am counting how many rows are similiar on two tables that are identical, and the rows should be identical as well. I am running a select count(*) where exists query and it takes 5 hours to complete.
Each table only has two million rows.
What can I do to speed it up?5 hours to process 2M rows does sound a bit long :(
I didn't see this mentioned explicitly, but I thought the idea of comparing data on 2 servers implied a database link. Tuning distributed queries can be nasty.
Start by getting an execution plan of the query to figure out what it is doing. Compare that to the plan generated by the already suggested MINUS operator. You'll need to do MINUS twice with each query in the other's position the second time. Alternately, check the indexing on the subqueries; EXISTS tends to work best with fast indexed lookups. FTS on an EXISTS subquery is not good :(
Think about copying the data locally to one system or the other first, maybe in a materialized view or even global temporary table.
Finally, think about tuning the transfer. There are articles on Metalink on tuning the transfer packet sizes (SDU/TDU) which might help IF YOU ARE ON UNIX; I haven't had any luck changing these values on Windows. You can also look into setting tcp.nodelay which can affect when packets get sent (another Metalink article should cover this). -
RMAN backup to SAN takes 13 hours
Hi All,
I have configured my RMAN to run through Recovery Catalog, and take daily full backup (limitation of Standard Edition) to a shared location on Test Server (\\testdb), which takes around 35 minutes to complete successfully.
The same full database backup takes 13 hours to complete on shared location to SAN storage mounted on blade server (\\blade5). To investigate further I opened an SR with Oracle Support and ran a series of test to take backup of a single tablespace (using target controlfile) on following 3 locations:
1. Local Hard disk of Production Server
2. Shared location on Test Server
3. Shared location to SAN storage mounted on blade server
Following were the results of the test:
1. The backup tablespace size is 1.36 GB with one datafile.
2. The backup piece size in all 3 test cases is 1.1 GB each.
3. RMAN Backup Time at 3 location:
3a. Local Backup Duration (D:\backup): 04:55 minutes
3b. Shared Backup Duration (\\testdbl): 02:25 minutes
3c. Shared SAN Duration (\\blade5): 26:25 minutes
Based on the above finding Oracle Support concluded that Oracle RMAN is perfectly fine and It is at the SAN that the problem resides, whereas the IT Admins state the problem is at the RMAN side.
My query is, how do we determine that Oracle RMAN is underperforming due to issues with SAN or blade server or network?
Regard,

When the backup is running to the SAN, you may want to see what RMAN may be waiting for from V$SESSION/V$SESSION_WAIT. In addition, you may want to enable tracing during the backup to the SAN and see if anything stands out from the trace file:
rman target / log rman.log trace rman.trc debug
As per your suggestion, I carried out the test again with tracing enabled.
1 Tablespace [with 1 datafile] size 1.36 GB used for RMAN backup.
Backup piece size: 1.1 GB

Why does the Install-SPSolution / Uninstall-SPSolution take exactly 8 hours to complete?
I asked this question
here before and didn't get a usable answer and I see other people are getting the same issue. I did some more testing, added a timer/t to my scripts and discovered that the Install-SPSolution / Uninstall-SPSolution always takes exactly
8 hours to the minute to complete, no matter when I start it. I verified this over several refreshes of my webpart and it is always exactly 8 hours. This applies to both Central Admin and farm solutions. I hope that the duration of 8 hours
to the minute does contain a clue to solve this issue.
This is the PS1 script I use to install the CA component:
param([string]$cadmin2010 = "", [string]$cadmin2013 = "")
Write-Output "Installing MySolution.CentralAdmin.wsp webpart"
Add-PsSnapin Microsoft.SharePoint.PowerShell
Write-Output "Loaded SharePoint environment"
$cadmin = $cadmin2010
if ($cadmin2013) {$cadmin = $cadmin2013}
Write-Output $("Installing webpart on " + $cadmin)
$sln = Add-SPSolution MySolution.CentralAdmin.wsp
Write-Output "Added solution"
Install-SPSolution -Identity MySolution.CentralAdmin.wsp -GACDeployment -Force
Write-Output "Installing solution"
while($sln.JobExists)
start-sleep -s 5
Write-Output "Solution installed"
Enable-SPFeature -Identity b2ff3a66-0f9d-4b4a-9b79-842aeca34d42 -url $cadmin -Force
Write-Output "Feature enabled"
It takes 8 hours before the "Solution Installed" message is printed. Once it completes, everything works fine, but with the uninstall of an old version and the install of a new version, 16 hours is a long wait. This is the output of my script:

Why did it say "Backup could not be completed"? Was it because it estimated the backup would take 3 hours and it timed out?
Welcome to the Apple Community.
First check that your device is correctly connected to the wifi/internet (settings > wifi)
If your back up continually fails, you might try turning off back up on your mobile device (settings > iCloud > storage & backup) and then deleting the backup file from iCloud by swiping the backup file on the mobile device (settings > iCloud > storage & backup > manage…) and then turning back up on again.
If this doesn't help, try turning off some items for back up in a pattern to try to establish if your problem is being caused by specific data on your device.
Being able to back up to the cloud can be very useful, especially if you don't have access to a computer or have infrequent access to one, however unless you specifically need to use iCloud for back up, you will find backing up to iTunes significantly more convenient and possibly more reliable.

Although it keeps actively finding problems with the disk, the progress bar hasn't changed for more than a half an hour, and it still says it's going to take an hour and 35 minutes. I'm starting to worry it will never be done! My laptop, a Macbook Pro, is pretty old - about five years, and I don't know if the fact that I've never run a verify disk permissions before has anything to do with it.
The only non-greyed out option is to currently 'stop permission verify'.Just let it run, it probably won't take that long. Also you may benefit from reading Disk Utility's Repair Disk Permissions messages that you can safely ignore.

Apple TV (Gen 2&3) takes several hours to load a movie from the iTunes Library
I know this had been discussed before, but a went through all posts that I could find and never found a solution. I will list below everything I have tried and if anyone else has ANY ideas I would be extremely greatful to hear them! To reiterate the issue any time I try to play a movie from MY iTunes library it takes several hours before it will even start playing. Now, to what I have already tried...
1. I cycled my router first and after that didn't work I completely took it back to default settings. My router is an Apple Airport Extreme
2. I completely uninstalled iTunes and then reinstalled it with full library, and then I also tried with just one movie in my library that I know used to work. My home computer is a Windows 7 PC.
3. I restarted my Apple TV, and also bought a Gen. 3 Apple TV and tried it new out of the box.
4. I have tried to stream on both WiFi and hooked up to an Ethernet Cable.
5. I have tried with all firewalls turned off on the PC and router.
6. I have ended home sharing on all devices and restarted home sharing on just the Apple TV and PC.
7. I have turned off all devices using WiFi in the home.
That is all I can think of off hand so if you have any other ideas please do not hesitate to chime in so I can try something else. Do know that my Apple TV used to not have any issues and worked great since I irst purchased the Gen. 1 Apple TV.
PLEASE HELP!!!!!!!I have the same problem. I just purchased the Apple TV software 5.0. Apple TV is working other than downloading movies. I have been trying to download one movie for the past two days. I have a wireless network, using AT&T DSL. I have tested the connection using the test option in the Settings area of the Apple TV, which passes.
I have also tried rebooting my Apple Tv and turned off all other wireless options. I am able to download Netflix movies using the PS3 without a problem, why not on my Apple TV. I hope I didn't just purchase this device to stream music and photos.
I hope someone has a solution to this problem.
By the way I just upgraded my modem and router (Airport Extreme).
Thanks for the help!!!! -
Hi,
I've just rented a movie, which claims its going to take 14 hours to download. Its still at it after 1 hour. To make matters worse, the 48 hours it gives you to watch it has already started and charged me an hour. There was a message to say I could start watching it now but it dosen't work. Please can you help?You'll have to wait till it downloads much further than. If your download says it will take 14 hours to download, you have a very slow connection. You would never be able to watch the movie until it downloads completly.

I have over 300 photos and 87 videos. When I recharge the battery I am geting the message to buy more storage to because not enough icloud space. So I did yesterday. That went ok, but the new message tells me it will take 83 hours. Perplexed I went thru the settings and turned off apps and their data that I didn't realize where on. Now I'm not sure if I needed to purchase more storage but it is still taking forever to complete the task. Am I on the right track with this, meaning will take forever to store all my photos or what ? The only other item I have on to store is contacts. Can you assist me ? Thanks - emoslim
Welcome to the Apple Community.
The first back up to iCloud may take some considerable time. Just how long isn't really possible to say without knowing how much is in your back up and your connection speed.
What many people don't realise is that upload speeds are often significantly less than download speeds, so for example a user may have a download speed of 40 Mbps, but only 1 Mbps for uploading. As a rough guide it will take around 2 ¼ hours to upload 1 GB of data at 1 Mbps.
