OWB 10.2.0.4 really bad set-based delete performance

Hi, we recently upgraded to OWB 10.2.0.4, with one of the reasons being the ability to do set-based deletes instead of row-based. However, upon testing this, we're seeing maps that in row based deletes go from 30 - 40 seconds, now taking literally 1.5 to 2 HOURS to run.
I expected the SQL from the set based to take the form of:
delete from my_table
where (col_a, col_b, col_c) in (select a, b, c from ....)
but instead the format is different:
delete from my_table
where exists (select 1 from ....)
I don't quite understand what the SQL is trying to accomplish - and truthfully, it performs horribly compared to the hand-written version (explain plan shows estimated cost of 14,000 for my query, and over 5 million for the OWB query).
Has anyone else seen this - and is there a solution? Part of me wants to say I'm doing something wrong, but the other part says "sure, but it works fine in row-based mode(target only)" - exact same map.
Any ideas?
Thanks!

Hi everyone, we'll I've figured out what is causing the problem and how to fix it...but still don't understand why it causes the problem.
Here's a high level overview of the ETL - we find deleted record by selecting business key columns from our existing dimension table and doing a MINUS on the matching columns from the source table. If any records come out of this, it means the record was deleted on the source, and we go ahead and do a matching delete on the dimension table.
Here's where the odd thing happens though - there's a column called "source system name" that is part of the dimension business key. This column does NOT exist on the source system - it's just a hard coded constant (put in just in case we ever add an additional system in the future).
Basically, if we do the minus logic on all the columns EXCEPT for this one, and then connect a constant to the delete operator that has this hard coded value in - the delete takes FOREVER... On the other hand, if we actually put this field into the minus operator by simply repointing the existing constant there instead of directly to the delete table...the deletes magically start taking 30 seconds instead of 10 minutes to run.
No idea (at all) why this makes a diff, but it seems to - and it's a day and night different.
Hopefully this can help someone else out who runs into the same issue.
Thanks!

Mail handles .Mac really badly-what's up?

Since I put my .Mac email account into my Mail application, it has worked really badly and I am considering just deleting off the .Mac account and not using it anymore as it is so annoying. Essentially, having the .Mac account in Mail slows everything else (my other email accounts) down to a ridiculous level. When I check "All", and sometimes when I send even one email, the Activity Viewer shows me that Mail is struggling to open .Mac mailboxes and stuff like that, and while it is struggling to do various things with .Mac, including synchronizing, the other email accounts are held up in the queue (ho hum... very boring). To prevent this, I went into the .Mac account and unchecked the "Include when automatically checking for new mail", but this has no effect whatsoever, probably because I usually check for new mail manually anyway.
I have two Macs at present, an older G4 flat panel iMac (1.25 Ghz), and a brand new dual core intel MacBook (2Ghz) and the problem is exactly the same on both Macs. Anyone having similar problems or knows a fix to this? Would love to hear!

There is a setting under the Advanced tab for the
account preferences to not keep all messages and
their attachments available for offline viewing but I
don't use this setting and don't experience the same
problems.
To clarify, do you mean that you "do not" keep all messages (etc.) available for offline viewing, or that you "do" keep all messages (etc.) available? At present, I have this option to "keep all messages and attachments available for off-line viewing" checked positive, by default I presume.
After first creating the account if there
are a number of server stored mailboxes and messages
available on the server, the mailbox and message
synchronization process takes longer than normal and
the time it takes for subsequent synchronization
should not be a real long process unless a number of
changes have been make with server stored mailboxes.
Odd thing is that I only have one saved message in the .Mac account, and that is a tiny weeny one (about 10K) with no attachments or anything! By the way, since I have just been going through everything all over again, I notice that what really seems to be holding things up (I've now changed synchronization to "manual" on both computers) is when I "Get Mail" and Mail is trying to open the .Mac mailbox - this goes on interminably (as I can see in Activity Viewer).
Try using the Rebuild Mailbox function on all server
stored mailboxes. All messages will disappear
temporarily and the mailbox will be resynchronized
with the server.
Sorry for being dense, but I've been all over my Mail application and all over my .Mac settings and I can't find this "Rebuild Mailbox" function. Could you please tell me exactly where I can find this Rebuild Mailbox function?

Video quality in scope is really bad and dark

When I send my sequence from Final Cut Pro to Color, why does the video in the scope area come out so bad where I can barely see anything? Basically the video is nothing like the quality in final cut pro and the picture is very very dark.
When I see the tutorials online of the videos being sent to color from final cut, the quality is exactly the same and they don't do any adjustment.
Can someone please help me fix this? I work with AVCHD. Thanks!

Thanks George.
Now the quality is not "really" bad anymore, it is bad. ;-)
The quality got better, but still there is a difference between drawing shapes and cell borders. And the difference is causing problems with customers, who are demanding professional quality.
Here is a .jpg of the original Excel table. The drawing shape is the outer one, the cell borders are the lines beneath the data. Both line types are very delicat. This is how it should be.
And this is how it looks after a pdf-print with setting "high quality print" (2400 dpi).
The outer drawing shape is ok. The thin horizontal lines are twice as thick than before.
I know, it is about details. But those details make the difference between a professional and an amateur performance.
Do you have another idea, how to improve the pdf quality?
Thanks for your help so far, I appreciate it.

Screen flickering really bad after unplugging external monitor

Hello,
Since I updated my Macbook Pro 13' Retina (inch, Early 2013) to Mavericks, almost averytime I unplug my external monitor or TV, the screen starts flickering really bad. This is the screenshot of the issue. Sometimes you can see all the apps opens, but the "flicker" effect takes over the screen, making it impossible to user the computer. The only way I found to use the compuer again is restarting it. It's really weird.

Howdy inireugg,
We've an article that provides a host of helpful information and tips for resolving issues with displays.
No video or no signal, image distortion, "snow," or flickering
Check connections
When using an external display be sure to check the following:
If you're using an Apple notebook, confirm the AC power cable or adapter is securely connected to the computer and the cable providing power to the display is also secure. It is always good to have your notebook connected to AC power when an external display is in use.
Confirm display adapters are fully seated in their respective connections and that they are supported models and for the computer and display. Refer to these articles to assist you with adapter compatibility and further configuration information:
Monitor and Display Adapter Table
About Mini DisplayPort to HDMI adapters
Apple Mini DisplayPort adapters: Frequently asked questions (FAQ)
Thunderbolt ports and displays: Frequently asked questions (FAQ)
Remove all display cable extenders, KVM switches, or other like devices and retest to determine if the issue is resolved.
Try unplugging the video adapter or cable and then plug it back in.
If more than one video adapter is in use (or "daisy-chained"), troubleshoot by using only one adapter.
Example: A mini DisplayPort to DVI adapter connected to a DVI to HDMI adapter is an unsupported configuration because there is a series of adapters in use.
If available, try using a different display and or adapter (or use a different connector by using DVI instead of VGA, for instance).
Reset the systemYou can reset the Mac's parameter RAM and SMC.Reset the resolutionStart by resetting the Mac's parameter RAM. If the display does not come up, was previously set to an unsupported resolution, and still results in no video:
Start up in Safe Mode.
From the Apple () menu, choose System Preferences.
Choose Displays from the View menu to open the preferences pane.
Select any resolution and refresh rate that your display supports.
Restart your computer.

Convertion from pdf is really bad

Hi !
First, i m pretty ignorant in making pdf form...
I need to make an interractive form from a pdf file (25 pages) given by a friend.
he gave me 2 version of the file, a 'normal' pdf and one in form version (without any calcul or interractivity).
(but it lacks 3 fonts)
I tried to make it with Acrobat :
with both version of the file,
i c'ant find all the events i need in 'Action' tab when i try to add some code on a textBox like 'change', 'docReady'...
But the way i can make the form is really good. In fact i only need to add textbox, radiobutton... i don't want to edit text.
With LiveCycle i create a new document from the pdf and i select interractive. i need to change tooltip, visibility of objects..., wich can t be done with non interractive form (if i understand correctly ?).
my problem is that the converted file is really bad, the convertion log contains a lot of errors.
and it will take me a lot of time to correct, adapt it, plus, images are pixelised ( why ??).
My questons :
Can i make interractive form without converting the document ? like with Acrobat or non interractive forms ?
Is there a way to have a source file instead of the pdf ? wich contains images, fields... so there will be no convertion.
Thanx for reading

Thanks George.

Why do the photos in my first InDesign project look really bad?

Why do the photos in my first InDesign project look really bad? Noticed as I "placed" them, some PDFs or JPEGs (not photos, but PDFs converted to JPEG) looked pretty distorted. Went ahead with the 60+ page project, converted to PDF, sent to client. He converted to a flipbook to proof and really didn't like the photos. Here's the irony. Upgraded to InDesign for this client. Was using Publisher as a standby until I could afford InDesign. Signed up with the Creative Cloud because job was overwhelming Publisher.
I started the job without a whole lot of knowledge (or patience for the tutorials) and figured I just wing it (and get InDesign for Dummies). Am thinking somethingw as screwed up in the initial setting up of the job. So how do I figure out if this is the issue and can I fix it without redoing all 60+ pages. If anybody has an answer, please let me know.

Ok, first image on your indesign page or any other program for that matter are still images, they are no longer pdf's, jpg's, psd's, etc. Once they load into a program, the file format is no longer relevant until you save again. Onl;y on your drive is the format relavent.
Second, if you can help it, never use jpg's until you are completely done and will be sharing a jpg. Jpg's are a lossy format are are not the best for preserving quality on your drive. Each time you open a jpg, and save a jpg more data is lost, as that is how that format compresses the data, by throwing it way for ever.
Third, the problem may not even be with you, it could happen when that person created a flipbook. That is an unknown varible, one which could make you look bad when it had nothing to do with you.
Fourth, Pay attention to the pixel dimentions of your images, the higher those values are the better the quality. Scaling can and probably will reduce that quality. If you can, it is better to hide parts of the image by cropping with a frame than it is to scale the image. you can scale, but pay attention to it.
I will stop there for now, as some of what I wrote is based on assumtions. That normally does not work out too well.

Why would apple not automatically show the side bar in iTunes. Wasted 20 min trying to find out why my ipod was not showing up. Really really bad idea, Apple.

Why does the side bar not automatically show up when you first download apple iTunes? Really really bad design. It took 20 min to fine the setting that enable the side bar. ***? I could not access my iPod for 20 freakin min! Just show the **** side bar always! Maybe apple is too big and is starting to lose common sense.

Because Apple update iTunes to do it that way. Apple has not said why.

My iPads Internet is really bad

My iPads Internet is really bad everything else in the house is fine and its not that everything else is is hogging the wifi because it has been fine for ages but all of a sudden it's being really bad, does anyone know why?

What is really bad - slow, drops connection, won't connect, short range? You need to provide specifics if you want an answer.
Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Photoshop CC really bad lagging on new rMBP

I resently bought a new Retina MacBook Pro 13" with a nice fast 2,8 i7 proccesor and a big chunk of 16 Gb ram. After using it on my older iMac I was exited to use it on my new MacBook. But its lagging really bad. It makes it unusable for me. I don't work with large files and we mostly use it for small UI design. I use a Bamboo Wacom and use OpenGL is on. when turned of its a lot faster but this results in masive graphic bugs.
Anyone know how to fix this? Because I'm really thinking of switching to Sketch 3 (http://bohemiancoding.com/sketch)

Well, something is up with your system to make it slow.
Do you have any third party plugins? Have you tried disabling them?
Do you have any utilities that would interfere with other applications (antivirus, firewall, etc.)?
And the "graphics bugs" mean that you have a driver problem which will have to be addressed by Apple.

Firefox behaves REALLY badly at random times and I'm worried about it?

So here's what happens. This happens at random times, unexpectedly. I click on a new link, any link, and suddenly, Firefox blares up, automatically turns to private browsing, and goes to a bunch of random websites.
Then, it lands on ''www.xnxx.com'',(<sub>'''edit''', un-linked -J99</sub> ) which I have identified to be a pornography website. After that, it suddenly picks on a random porn video and crashes before the video plays.
This really worries me, because just before this first happened, I had done a quick scan with both Microsoft Security Essentials and Malwarebytes Anti-Malware Pro, and there was absolutely NO problem.
Not only that, I had gone only to trusted websites.
I'm a high school sophomore, so this could turn out REALLY badly for me if someone sees this happening and thinks that I'm TRYING to watch that stuff.
I have already sent a crash report to Firefox and included the website that I crashed in, which is the porn website. I haven't sent any other details, though.
Could I be getting hacked? I don't think so, because this only happens with Firefox; Chrome, Opera, Maxthon, and IE don't have this problem.
I'm running Firefox 15.0.1 in Windows 7 x64 (why the crash report said Windows NT x86, I have no idea).
PLEASE help me fix this!

On looking at your System Details aside I note that you include a Crash ID.
That particular crash is probably related to use of Norton software. You may find that you can use the Norton security software without crashes if you disable the '''Norton Security Safe '''feature (Please confirm - or otherwise - that you are using that ). Note I am not suggesting you turn of the security software, just the utility/toolbar.

App for Windows 8 are really bad

The apps Microsoft made for Skype are really bad.
Any chance for a update so you have some chance of getting to things like call and chat and make it more clear who are online.
Out of a lot of bad apps for windows 8 this take the cake!!

Is there a reason "Elaine" (http://community.skype.com/t5/user/viewprofilepage/user-id/88058) had to edit/moderate EVERY one of the posts here?
This thread started some time ago, so please correct me if I'm wrong, but it looks like the word "sucks" was replaced with "are really bad" in the last 12 hours.
The only reason I bring this up is because this is censorship and let me tell you Elaine that it is NOT helping Microsoft/Skype's case here!
If something SUCKS it means it IS REALLY BAD. The word "sucks" is VERY well known throughout the english speaking world to mean this. Any moderation on the grounds that the moderation was done "In deference to international sensibilities" is ridiculous! This stinks of corporate censorship!
Rather than censor everyone's comments, how about you (the company) just fix the issues and let us know they are fixed OR if fixing them isn't going to happen in the near future at least let us know that you're working on it!
I have not seen even one official comment by Skype or Microsoft staff regarding this issue! NOT ONE! That implies to me that there is something seriously wrong and its almost definitley not going to be fixed any time soon!
Perhaps after all these years of being a happy customer it is time to start looking at moving away from Skype to another service...

ITunes 11 sounds really bad any fix?

I noticed that the new iTunes sounds really bad compared to other players like VLC or Quicktime any idea how to fix this.
I tried to adjust the equalizer and the sound enhancer and no luck, it is definitely not the speakers because the same song sound great with VLC or Quicktime, all I try to download is high bitrate songs like 320 kbps.
Appreciate any help!

Hi Doug,
Not at the moment unfortunately. Apple did use the glass effect shelf dock on the side in the development versions of Leopard, but took it out and only used it on the bottom in the final release because of a few problems with the reflection and stack effects. I'd bet that within a few months they'll be rolling an update out which will give you this option if you really want.

IPod lags really bad...

My iPod is lagging really bad, it takes about 15 seconds to load a song and sometimes just totaly freezes up. It was working fine yesterday but just all of a sudden today it started freezing up. I tried to restore it but now today my computer doesn't see it in iTunes. I went through all of the steps apple recomends but it didn't help.
Thanks

it sounds like a hard drive issue to me.. you might be stuck sending it in.

Lock button not locking phone and sound thru earpiece really bad

Hi, have an iPhone 5, within a few months the lock button failed to lock my phone and during a phone call the sound thru my earpiece is really bad distorted and sometimes intermittent. ( not due to signal tho)
Are these common problems and will apple fix them or give replacement??
Many thanks

Well, if only a few months old then you are under the 1 Yr warranty that comes with the device, either contact AppleCare or visit an Apple Retail Store
