InterMedia search within report components causing Oracle to run at 100%cpu

Hi,
Running Win NT SP5
Oracle 8.1.7.1
IAS 1.0.2.2
Portal 3.0.9.8.1
I have a table with an intermedia index.
My report query has :
AND contains(i.description,:b_description) > 0
This appears to be the reason why my application components sometimes run othertime doesnt. It also seems to have caused my CPU to go to 100% .. such that Oracle process taking 100% CPU.
Take out this line.. and everything works fine!
Anyone else experienced this, any fix available ?

Oracle.exe is consuming 100% cpu o windows

Hi,
We have 6 oracle 10g database on windows box and from task manager we are able to see oracle.exe is consuming 100% cpu
Need to know this oracle.exe belongs to which database and can i get the sql for this process
Thanks

On my Vista PC, I find that the easiest way to identify which instance an oracle.exe is, is the task manager. On the Processes tab, right-click the oracle.exe and then click Go To Service(s) and that takes me to the OracleServiceORCL or whichever insance it is.
I'm sure there is a better way that a Windows person could tell us about. Then having identified the instance, it is just normal tuning from there.

Safari causes my computer to run at 100% CPU Usage!

For the past few days Safari has been causing my CPU to run at high rates. This basically causes me not to be able to much while Safari drags and loads pages. I need a solution to this. I tried resetting Safari but that didn't work. Please help. Thank You.

My PC runs at high rates too. And I too like to use iTunes at the same time I use Safari.
And there's no quick solution to this...at least not yet. But here are few tips and tricks that you can apply to get this thing half solved.
1. First of all, if you don't intended to watch images while browsing, You can turn it off...Simply by going to 'Edit> Preferences> Apperance (Tab)' and from there deselect ' Display images when the page opens'
2. Secondly, Don't open too much tabs if it's not needed.
3. Thirdly, if you're using Safari for a few hours. Just try to close the whole window time to time. And after reopening get back to the last session (View) by selecting History> Reopen all windows from last session'
This will probably help you. Btw, these tricks are exclusives from me. Happy Surfing buddy!

In Oracle 10g,nmupm.exe runs at 100% CPU usages

Hi There this is Bal Mukund Sharma from Computer Associates,HYD.I have recently installed Oracle 10g on windows 2000 server with 1 GB RAM,i have observed that nmpsupm.exe which is under the bin directory under c:\oracle\product\10.1.0\Db_1\nmupm.exe.is consuming all CPU resources.
when i set all Oracle services to manual and restarted the machine then it shows normal CPU usages. Can you please suggest something regarding this.

Oracle 11g R2 consuming 100% CPU on execution plans

Hi Friends
I just installed oracle 11.2.0.1.0 on Windows 2008 Server R2.
I got 4GB of RAM = 2536MB for SGA and 600M for PGA
I'm running a processes that is consuming 100% of CPU ant its showed on execution plan of every statement this utilization.
I have worked with disk_asynch_io parameter to FALSE and had no improvement on performance.
Reading a doc relating to a bug I set up the dbwr_io_slaves to 4 but no changes.
Now I'm stuck on asynch descriptor resize wait event for more than 4 hours.
Any ideias os tips or experience about this issue?
Tks a lot

Well, Tks for your help guys,
The problem was solved "almost" at all by disabling MEMORY_TARGET and SGA_TARGET and setting up all the memory parameters manually.
This has eliminated the event "asynch description resize" and the overall performance of the DB has increased. I was able then, to complete my operation.
I believe its a Windows bug or a poor design or configuration of mine. But at this time we are able to run the system well and fast enough.
Tks a lot

Cairo-clock causing X to run at 15% cpu

I'm running a core 2 duo 2.8GHz with openbox and added cairo-clock to my autostart.sh using
cairo-clock -x 1500 -y 0 -w 400 -h 400 -s -i -t neon &
Also when I kill cairo-clock and then x server and open up a new x session, my openbox process will run at 50% sometimes.
Very weird. Anyone else have a problem with this or have some wisdom on this issue?

I tried it with a bunch of other themes and starting from the terminal and still seeing X at 10% +

Problem in using Intermedia search with Oracel 9i DB on Red hat Linux

Hi,
I am unable to search a particular text in a blob using Intermedia search feature.I am using Oracle 9i (9.0.2 version)mounted on Red Hat Linux OS.
It works well on a Windows 2k OS.
To be more precise the following query fails when I pass the INSO_FILTER as the parameter.
"CREATE INDEX WM_WORKDETAILIDX ON WM_WORKDETAIL (WM_ITEMDATA) INDEXTYPE IS CTXSYS.CONTEXT Parameter(CTXSYS.INSO_FILTER)".
Any Help towards it is highly appreciated.
thanks & regards /Ravi

How to optimise the intermedia search query when using contains?

HI there,
I have a query to search my database in two tables on eight columns. So that I have eight indexes which are in a different tablespace. Now I have written a query like
select * from table1,table2 where
contains(col1,'wordlist1', 1)>0 and
contains(col2,'wordlist2', 2)>0 and
contains(col8,'wordlist2', 8)>0 ;
When I tried to execute this query, my databae is getting very very slow. As soon as I started the database its working fine, with in five munites of continuous checking, the database going to be slow. So
How can I optimise my query? Is there any better way to search the database using intermedia?
Any help or any sites list on intermedia searching utilities, other than the Oracle documentation is thankful.
waiting...
khaleel

Thank you Thomas,
I need some more from you...
If I have 8 tables for 8 columns, then how do i proceed?
Also could u tell me some query optimization techniques while working with intermedia text.
Thanks you once again,
waiting...
Khaleel Hi Khaleel,
I think this depends on your data model (relationship between the tables) and how you like to search later.
The optimization begins also with the create index statement (memory clause and storage clause).
If you like me to help I need more information about your hardware, os, datamodel and what kind of searches you will have later.
Cheers,
Thomas

Is it possible to integrate Oracle intermedia search into apex ?(1)

Or do something similar manually yourself in oracle xe ?(2)
(1)I've been reading through part of the documentation of the intermedia search, and find it quite intresting. Better to use that if one can, then to have to do that it manually or yourself. But all I read is about JSP and PSP, and I guess PSP's are used by apex, but I was wondering if there was any way, to integrate intermedia search into apex, so that one can lookup say mp3, video files and images and display them in apex as well. Images may take some work but would I suppose be possible.
However for the other two you need also player software to play both of them. As far as I know this is not integrated into Apex, but could possibly be provided by using the player integrated with a webbrowser, and by linking it to apex. So the browser is launched and plays the video or the audio file or alternatively a player is launched that allows to do that. But correct me if I'm wrong.
(2) Alternatively I was wondering if one could do this, manually in Oracle XE, but then manually, by making tables with blobs and putting the files in there, and then finding somehow a way to get them played by a player, or to have them be put in a directory, and/or erased from that directory, and modify the player, or let it be activated and controlled by some kind of script to look for new files, and then play them off . Could this be done, by adding a parameter new_file_to_play to a message passed to the player, or the program governing the players behavior ?
I know this sound difficult, and it probably is, but it would have its benefits. I suppose a simple answer would by, why not use oracle 10g with intermedia search ? Well because although I expect this to be the preferable choice, the license is rather expensive for me, and if I could get a rudimentary version working on XE, even having to do it myself, and writing the code as well,
it would be ok.
I just wonder could one not, make a table, with a nr, a blob, and then the specific fields for the specific information of that type, and then use a extraction program that extracts that information from a file, and puts it in a xml or csv file, so that say after the images were uploaded, one can load the details in as well ?
It is more work, more complicated, and not as easy to use, but it could work I suppose.
Any comments are welcome.
Best Regards,
Floris

You should be able to add a menu option to Oracle E-Business Suite that just calls out to the URL of your ADF 11g application.
