Db_writer_processes and the location of the redo logfile
Is any beneficiary relationship between the number of the DBWR and the location of the redo logfiles? i.e if I spread out the redo logfile to several disks, will that benefit system with multiple DBWR? My system is 10g r2 on AIX 5.3 L with 4 CPU and 4 HDs (73.6 G each).

will that benefit system with multiple DBWR? NO. DBWR writes modified db buffers from the buffer cache to disk (datafiles). So multiple DBWn helps speed up the process (not for Redo Logs)
One of the benefits you get from spreading out the redo logfile to several disks is easier recoverability against damage(with different log members on different disks). This is because LGWR (not DBWR) writes the same redo information to the multiple logfiles you greate.

I have problem with Itunes losing where podcasts and some purchased music is located. Don't know how Itunes losing the locations of the files and I can't find the files on my hard drive. What can I do to stop Itunes losing location and restore my files?
Try assigning Queen as the Album Artist on the compilations in iTunes on your computer.

I have moved my library to an external hard drive and changed the location of the iTunes media folder in Preferences, but every time I close and re-open iTunes, I have to do it all over again. How can I make the iTunes media folder change permanent? I have an older machine with Windows XP.
I don't believe mounting the hard drive should be necessary, unless you have several external drives and want your computer to recognise them as folders, rather than drives. I've never had to mount a hard drive, ever. If you don't know how to do it, then it shouldn't be necessary now.
Try this:
Prepare iTunes so that it can see the external drive.
Make a note of which drive-letter the external drive has been allocated. (Look in Windows Exploer)
Look at the file location for a song. Make sure it plays (and therefore that iTunes has found it). Highlight it and select File/Get Info/Summary>Where: and make a note of the drive letter for that song.
Close and shut down the computer.
The next time you turn the computer on again, connect the external drive
Before you start iTunes - check the external drive in Windows Explorer. Is it ready, does it have the same drive-letter that it had last time? Can you go into the drive and see the files on it?
Once you can, start iTunes. (If the drive lettter has changed, you need to work out why before going any further.)
If iTunes fails to find your external drive, you need to check where iTunes is looking for your Library.
Select the same song you checked before (presumably iTunes can no longer find it). Follow the procedure for locating it. You should be able to see where iTunes thinks the file is. It's the drive that counts. Which drive letter is iTunes looking at? Is it the same one that it was previously (which should also be the same one that the drive has now).
What happens, which step do you have problems with?

How do I change the location of the coldfusion-out.log and coldfusion-error.log files in CF10
When I change the log location in ColdFusion Administrator it changes the location of most but not all the log files. I have a requirement from my customer to place all log files on a separate partition on the server. For ColdFusion 9 I was able to modify the registry settings to change StandardOut and StandardErr for the ColdFusion Jrun service. This does not appear to the case for ColdFusion 10 which now uses Tomcat 7.
I tried modifying log4j.properties file and was able to relocate the hibernatesql.log, axis2.log, and esapiconfig.log but not the coldfusion-out.log.
I am running ColdFusion 10 Enterprise Edition on a 64-bit Windows 2008 Server.The location of the rest of the ColdFusion logs can be changed in the ColdFusion Administrator. Go to the Debugging and Logging section, Logging Settings. There is a form at the top of the page where you can change the log storage location.

As per adobe agent chat representative, the following question is posted on the fórum to obtain an answe from adobe.
What is the location for the swatches file in the illustrator product part of Adobe Creative Suite 3 Design Premium for windows (date and lenght)? File that manges its funcionallity.
Thanks
<moved from downloading,installing,setting up - kglad>Illustrator is not working as it should...
I want them to compare the original size and date of creation with what I have installed on my computer... I have installed several times with my original CD and I tried once downloading the files from the adobe site (using my own license). I suspect the files has been modified or renamed on my laptop by an external unauthorized user causing the malfunction of the application.
Customer services does not support CS3 anymore and the updates / patches in the adobe site does not solve the problem... They redirect me to the forums for support...
Presently, my problem is that after creating a swatch and drag it to the swatch panel, it does not fill as it should a new form... Now, after deactivating and activating my license the swatch seems to fill the new form but when the filter that the swatch has is persistence in the next filling object created even though a different color is being used as a fill (X)... Help in the creation of a swatch over the internet just complicate the issue.
That's why I would like to know whether updates on my product are being received or files are being replaced without my knowledge...
Thanks...
PS Do you know how to contact a staff adobe employer on the forums? -
Making the frame same size and same location as the field.
In my report, some frames only contain one field. To save space, I need to make those frames same size (same width, same height), and same location as the field. It means the size and location of those frames should exactly match their fields.
But, for those frames which only consist of one field, when I use the mouse to adjust their sizes and location to match their fields, Object Navigator will show that their fields moved outside of them. Is there anyway to solve this problem?Hello 1011308
Hi in your case check out the lock object option into report builder.
After Putting filed into parent fame , if u off the lock option , then field can go outside.
just check onces.
Thanks

Is there an option to have the location of the file on each document? (ie. S:\Policies and Procedures\Work Day\Time Sheet.xlsx)
I am looking for an option that will allow this on each of our documents for an easy access. It may already have an option, I am just unaware of it. Any help would be greatly appreciated.For starters, can you tell us what software you are talking about? I can assume Adobe Reader but you use .xls in your example.
If you are talking about Adobe Reader and pdf files, then unfortunately the answer is no. If something else, please be descriptive about the issue so we can guide you to the right place. -

Is it possible to make flash detect the location of the mouse and....
Hello
I'm looking for a script in AS2 that can detect the location of the mouse and when you leave the zone it trigger an action. This script need to detect the location of the mouse without interference of any other object inside the zone ( that include button ) and without "blocking" those object because of the invisible zone that could be on top of it.
I know the trick about the invisible button where you detect the mouseover with it, when you place it under all your stuff ( so that your mouse can navigate in peace ).
The main probleme will be that tee flash will be smaller than the viewscreen so it need to detect imediatly and at any speed the mouse leaving it's location. So the button trick is a no-go because too slow. Also because the website will need to auto-adapt to your viewscreen.
I need to be able to set the X and Y position of the mouse and i don't know.. does it require to put in the script the boundary location of the zone itself ? left top bottom right side ?
Right now i have a flash of 2000 px large and it is centering itself perfectly, But however, i get a horizontal scrolling bar that i want to get rid off. I am exploring all possible solution.
Dreamweaver forum link : http://forums.adobe.com/thread/613249?tstart=0 about my probleme with more detail. I am considering resizing the flash ( and having to move everything inside it for that... ) down from 2000 to 950px large, So when the user leave the zone inside the flash in a quick move the script need to detect before it leave the flash zone. I know that AS3 so it, but i have no time nor ressource to translate to AS3 the whole flash.
Thanks !Probleme solved without having to change anything in the flash.
The solution was to add a small part in the CSS in HTML
html {
overflow-x: hidden;
overflow-y: auto;
Solve probleme. All browser. VERY usefull to know ! -

Is it possible to change the location of the Oracle logo
I need to change the location of the Oracle logo in home page from left to right side. We tried to edit in common .css and failed. Please help.
The logo is in it's own table cell - so css will not work (can't change the order of table columns using css). You could possibly replace the logo image on the server with a single white pixel (create a custom skin if you want), then add a new background image to the table (class is HeaderTopBar) aligned right and no repeat using CSS. You would need to pad out that right side somehow to make it align (the last cell has class HeaderPageStatus and contains the status image).

How can I find the location of the signature used in the Adobe Reader signature feature?
How can I find the location of the signature used in the Adobe Reader signature feature? I've been using the signature feature for a while now and it works great and I'd like to use it on another computer. However, I forgot where I stored the signature. Adobe finds it with no problems (the signature pops up when I click "Place Signature"), but I have no idea where it is.
Hello,
It's here - C:\Documents and Settings\username\Application Data\Adobe\Acrobat\10.0\Security\

Got prompt "the location of the document cannot be determined" then presentation GONE!
I'm freaking out! I hope someone can help.
I started getting the prompt "the location of the document cannot be determined" as well as asking me where the movie "VIBCPart1" was, which I thought was odd, as that was the name of the presention - not a movie file. Then Keynote froze - that is, I couldn't save anything and it making me force quit it, and I did.
When I went back to open it the entire preso was just gone - not in the folder at ALL. I did a search - nothing. I do have a duplicate for a backup but I did 12 hours of work on this project today - and I use Backblaze so Time Machine was turned off. And yep, there is some kind of problem with Backblaze! I await their response at this point.
I have a lot of videos in my Keynotes - I often split my presentations up into smaller parts because of that to avoid huge files. I suspect this one got big. In any case, if anyone has any ideas on recovery and how to avoid in the future, I'd be very grateful! Thank you in advance!Only lately this started to happen to me as well. Problem happens in all iWork applications. Fortunately the apps never locked up completely.
When I try to save a document, I get the dialog that the location could no be found and whether I want to Save As... When doing a Save As the original file is still there and the dialog prompts for overwrite permission. I could save my documents. Just the other day Keynote magically found the document location again when I cancelled the dialog and then right clicked on the document title. The path to the document is correctly listed. I clicked the enclosing folder name on the popup (which did not open, resp. the Finder did not come to front), but a subsequent Save (command-S) worked
Very strange and deeply troubling.
Another observation: after it happended some days ago I ran Disk Utiltiy Verify and it found some problems, which I repaired successfully. Just now I had the very same issue again and right away ran a disk verify. AGAIN issues with the disk (Incorrect block cound for a file, volume bitmap needs minor repair for orphaned bocks, invalid volume free block count). Could this be SSD related (MBP Retina with 750GB original Apple SSD)?
Edit: some typos corrected -
Error saving: The location of the document " DOC NAME " cannot be determined.
I am having issues saving .pages files on to our network drive after upgrading to Mavericks and Pages 5.0.
A bunch of errors and issues occur when editing old or saving new pages files on our local SMB server. Saving files on to my local machine is fine.
I cannot save to the original network location at all. It errors: The location of the document "<DOC NAME>" cannot be determined. The folder in question has permissions that have always worked before the upgrade of mavericks/pages. I can rename the files in question, and save other types of files in to that folder without issue.
When it errors, it provides the option to Save as... this also fails, no matter where I try to save it to - local or network.
The auto-save feature fails for the same reason. This creates several temp folders with blank pages documents in it.
Most disturbingly, it appears to be destroying the original file by renaming it to a temp file, that is henceforth un-usable. Luckily Ive got backups of the documents.
Help!Update:
The new version of Numbers also comes up with the same errors.
The previous version of both Pages and Numbers work absolutely fine still - have had to revert to using these for now. -
The location of the document ... cannot be determined - file save fails.
I'm a bit stuck here.
I just got a new mac pro, installed Logic 9 on it.
When I try to save my progress in the proj I keep getting the message:
The location of the document ** cannot be determined.
You can specify where to save it.
Needless to say this is quite tedious and can't really fly.
When I opened Logic 8 that was installed on another drive (previous system)
I got the same message.
HOWEVER, when I login as 'root' user (super admin)
I'm able to save my work just fine, both on Logic 8 and 9.
Surely I'm missing on some unix / system / permissions thing here.
Is there anything that can be changed ?
cheers
BilletI'm curious if you have changed your username recently? Perhaps Logic was installed by a different user? I've had a similar issue with pages and keynote which I had installed with a user in the admin group and login with a user in the staff group, which is the default user on Snow Leopard.
I have solved this by changing the permissions of the folder into which I wish to save my docs. Go to the folder above the folder you are saving to. For example, if you are saving to the /Users/you/Music/Logic folder then go to the Music folder.
From Utilities > Terminal:
sudo chmod -Rf 755 YOURFOLDERNAME
enter your admin password when prompted
For example I want to save to the desktop. I open the finder and go to my home directory then
sudo chmod -Rf 755 Desktop
That's it!
