Many to Many set up

Hey guys long time no hear :)
I have a conceptual problem (Using Jdeveloper 11g, with ADF Business Components) that I was hoping you could advise me with. I have 3 tables. Tech_Equipment, Terminal_Type, and Equipment_Terminal. As you may have already guessed they are in a many to many relationship with Equipment_Terminal serving as the intersection table. I have now just started doing the CRUD forms for all my tables and have left this for last.
What I wanted to do was create an af form to somehow do this but I am not sure how. I want the user to be able to add a Tech_Equipment, and Terminal_Type and for the Equipment_Terminal to automatically take from those 2 tables.
I was thinking of creating a 2 forms one for adding Tech_Equipment, one for Adding_Terminals, and a third for the Equipment_Terminal table, where the primary key would be auto generated and read only from a sequence, and 2 LOVs (choice lists) which would be based on primary keys from the other 2 tables (therefore enabling to user to only choose already existing Tech_Equipment, and Type_Terminal).
The problem I see is that Tech_Equipment has a foreign key Terminal_Type_ID which I made an LOV based on Terminal_Type name. So whenever you want to insert a Tech_Equipment you have to choose the Terminal_Type. This creates a problem when you have more than one Type_of_Terminal, and I want to show it to the user, as the choice list will only let me choose the one.
Any help and advice are appreciated

Epson R1800 prints v. dark despite many attempted fixes

i have an epson r1800 printer which i used successfully with early versions of PS and windows XP. now the prints are very dark with a greenish cast using both a macbook pro snow leaopard, and windows 7 both with ps5.
i import the pics first into LR3.
i have been on the fone for hours with epson high-level tech support and the best they/we can figure out is that the printer cannot handle the photpro color setting that LR assigns automatically. it only like prints that began as Adobe RGB 1998 and havent been re-assigned. those occassionally seem to work fine. but some do not. i have shots in jpg tif and digitized slides [tif] going back decades, so lots of issues included. nor is that is an all-round solution, but is there some way i can instruct lr NOT to use the photopro profile, but adobe rgb 98 instead.
if i go that route, my options then are importing into ps using smart object and opening in raw one foto at a time, a pretty cumbersome [and somewhat confusing to me] process. i do this in lr by choosing 'edit in' > 'open as smart object' and then in ps clicking on the thumbnail in the layers palette to open in raw. ot i can use bridge, thereby involving 3 programs. arghhh.
per epson tech instructions--and this was the first thing that gave me some good prints--i have set the workflow option at the bottom of the raw image in ps at:
adobe rgb 1998; 16 bit; highest mp available( 20 or 25mp even tho i am shooting at 18mp); 320 ppi. but it only works sometime.
or am i on the wrong track completely in trying to solve the printer problem. i have been thru many setting adjustments and nothing seemed to work until opened with the current workflow setting. i have tried, as both adobe and epstill darkson recommeded, having ps control the color and setting icm and management off. still dark.
if agsinst all recommendations i use printer controls color, epson vivid, i can get prttey good prints, but only if i print from LR. PS hates this setting.
i am awating a call from a high-level adobe techie.
my little head is reeling--and of course this all is after epson tried to blame OS, PS, LR, my monitor, and me. and adobe did the same casting about. but since the same dark image is happening with the mac laptop and windows desktop, none of these seemed likely. epson also suggested i buy another, newer printer, but then admitted that if the photpro profile was the problem, no joy.
any suggestions, help. i have gone thru much ink paper and hair tearing and dozens of on-line fora.

As remarked by other responders, this is not a problem unique to you, to Lightroom or to your printer; I have struggled many times, most recently with Aperture3 and an Epson1290 (my Epson 220 didn't show the problem at the same time, with the same images). Changes in driver, profile usage to names but 2 factors, all can screw things up.
My suggestions:
1. Make sure you have the latest drivers downloaded from the Apple Software Update window below the Apple icon at the lefthand end of your Finder menu bar.
2. use an appropriate profile for your printer/ink/paper combination; the only real solution is to produce your own, with something like SpyderPrine - I have one for each combination I use.
3. Select these in the Lightroom Print Menu at the right hand side of the window under "Print Job". Don't use "Draft Mode.", which doesn't allow the following choices. Underr "Color Management", put in your chosen profile and Rendering Intent (I use Perceptual, but, in my experience, they don't change things much).
When you click on "Print", an Apple print window opens, which shows the printer is not in control of printing; all the options are greyed out.
As an alternative, in the Apple Print Window, select "PDF". This will save the image as a .pdf, which you can print from Preview. In the Previerw print menu, select Color Matching/ColorSyc/Profile: and put in your chosen profile; when you get down to the Clor Management" option, coilor controls will be "off", showing that your choices will be used.
If things are working correctly, two prints, one from each route, should be identical; if they are not yoy have another proble, the basis of which I cannot imagine.

How Many Headphones on One Nano?

My daughter loves to take her Nano 4G to school and share music with her friends. She uses a "Y" adapter so two people can listen at the same time. She wants to extend that to three headphones but I am concerned the reduced impedence will destroy the Nano. Is my concern valid, or am I lost in 70's thinking?
How many sets of heaphones can you string in parallel on a Nano without destroying it?

I doubt you could destroy it, but people are going to have to listen awfully closely to hear anything. And the battery is going to have a much shorter charge time.

OS X losses many settings after every reboot

I have a macbook pro running 10.4.11 recently I have noticed that when I reboot many setting which were previously remembered are reset. Examples include the default applications (I use the program default apps), Endnote and iphoto think they have never been opened before and have lost all their recently opened files etc. Does anybody know where these settings are stored or why I'm losing them?
Thanks

Hi scobbie, and a warm welcome to the forums!
Endnote and iphoto think they have never been opened before and have lost all their recently opened files etc...
That part is really confusing, how could they possibly lose what they never had???
Let's start with Applejack...
http://www.versiontracker.com/dyn/moreinfo/macosx/19596
http://www.macupdate.com/info.php/id/15667
After installing, Reboot holding down CMD+s, (+s), then when the DOS like prompt shows, type in...
applejack AUTO
Then let it do all 5 of it's things.
The 5 things it does are...
Correct any Disk problems.
Repair Permissions.
Clear out Cache Files.
Repair/check several plist files.
Dump the VM files for a fresh start.
At least if it doesn't fix it, it'll eliminate a few questions.
Report outcome please.

Want to use FiOS TV via CableCARD - CSR insists I must lease at least one set-top box

Started looking into subscribing to Verizon using a CableCARD-based tuner, since I don't actually own a TV.
I did some research at verizon.com and ran across this page (important parts in bold):
CableCARDS
A CableCARD is a device that provides access to certain encrypted High Definition (HD) and Standard Definition (SD) digital programs without the need for a Set-Top Box.
CableCARD Features and Services
What digital programs can I watch with my CableCARD?
You can view all FiOS TV Standard Definition and High Definition digital channels to which you subscribe. You can also order certain Pay-Per-View events by calling 1-800-VERIZON (1-800-837-4966). Without a Set-Top Box, you do not have access to On Demand programming, the FiOS TV Interactive Media Guide, or other advanced features of the FiOS TV service.
So far, so good. I logged into my account, selected a package, and started the checkout process - and then encountered an odd question: "How many set-top boxes do you need?", where the options were a drop-down list starting with 1 and scaling up. There's an extra $12/month charge (plus taxes, of course) for just one box, and more for other boxes. No way to skip that step.
So apparently, according to Verizon's service rep... I need to pay $12/mo+tax for a set-top box that I don't need, and that will sit on a shelf while I watch Verizon TV through my fully-supported CableCARD adapter.

You don't need an STB or DVR, but here's the easiest thing to do - and I just did it, so I know it works.
Get the STB or DVR along with the Cable Cards. Get everything activated and working - including the cable cards - then return your STB or DVR, either to a FiOS store or via UPS. Voila, you're done and using only Cable Cards. I only have two Cable Cards on my account. Good luck.
INTERESTING.
I was considering doing this too. I originally had just a cablecard, then ordered a STB for another room. We don't use it so I wanted to return it. I can't!
Brb going to UPS store.

How to use Set type datasources ?

Hi,
Our team has recently implemented CRM for one of our clients and now are integrating BW with CRM. Thus are developing corresponding objects in BW.
In CRM, the team has created many set types and made those BW relevant as a result system created datasources for each attribute of the set type.
Has anybody used set types to extract data into BW?
Regards,
Vikrant.

Hi
go to this guide

SPOOLing in sql developer does not take into consideration SET ECHO OFF

I'm running SQL Developer 3.1.07.42 on Windows 7 64 bit with java 1.7
I have the following very simple script just to show the problem:
SET ECHO OFF;
SET FEEDBACK OFF;
SET SERVEROUTPUT ON;
SET VERIFY OFF;
SET PAGES 0;
SET HEAD OFF;
SPOOL c:\test.sql
SELECT 1, 2, 3 FROM DUAL;
SPOOL OFF;
/if I run it in TOAD 10.6.0.42 it creates the file with
1 2 3This is as expected (by me)
if I run the exact same query in SQL Developer 3.1.07.42 , it creates the file with:
< SELECT 1, 2, 3 FROM DUAL
1 2 3(the < above is actually ">" but the CODE formatting software is screwing ">")
but I don't want the ECHOed command to be spooled. For the life of me, I cannot find a way to disable the ECHO from spooling in sql developer.
Tried the same in 3.0.4 and 2.1.1 with the same (bad) result (plus some warning on some of the unsupported SET commands).
Am I missing something obvious? Cause like this, the spool command cannot be used in sql developer to generate a CSV file for example, because of the echoed command. And windows doesn't come with SED by default so that is out. (plus that my original script is integrated into a much larger and complex set of scripts and the main script using them is executed from SQL Developer as a company policy (so that everybody uses the same tool and the code runs the same for everybody))
Any ideas/suggestions are welcome
Thanks.

Hi Gary, you seem to have some extensive knowledge. I'd like to follow-up on this thread and try to understand why SQL Developer won't hide the code even though I'm already running the code as a Worksheet (I assume you mean Run Script F5 button in SQL Developer).
I generally develop in SQL Developer that does a lot of dbms_output to echo data using a Spool command. When I'm in SQL Developer I can't get the code NOT to spool, it typically is echoed directly in the spool file at the top followed by the dbms_output data. If I save the sql file and run in in sqlplus it only outputs the data (good). If I use @C:\xyz_script.sql and hit F5 in SQL Developer it only outputs the data (per your previous answer) -- good.
So why can't I hit F5 in SQL Developer in the script file and have it only output the data? It just doesn't work no matter how many "SETs" you turn-off.
Looks like Echo, Term, Feed are supported in SQL Developer, maybe supported means something other than work.

How do I fix the format of plot lines for an arbitrary number of sets of data plotted on the same x-y graph?

I have written a VI to control an LCR meter and perform sweep functions. I have two x-y graphs on my front panel (one for each of 2 measured parameters). The VI is designed with a button to take a measurement, plot the data, and then wait for another event (like write data, clear plot, or measure again). The user can take simultaneous measurements and these are plotted on top of the data already there in the same x-y graphs (using an array of clusters with shift registers). There is no limit on how many sets of data can be on the x-y graph.
Now, my issue is in formatting the plot lines (color, thickness, marker type). I can fix the first plot line by adjusting the parameters of the x-y graph. However, I also want to control the format of all consecutive plot lines. How can I do this for an arbitrary number of lines? The main thing I want to do is to have all of them show the square marker type (the default is no marker type, just a line).
Thanks!

Hi maximum23,
You can use properties of plot to format the plot lines. You just have to select Active plot using property and then select color and line width etc..
You can define color and width etc parameter by asking user or you can just make them default.

Advice of best export setting for HD

Hello. I am editing with CS4 and did my first HD project. Project setup was fine, used Sony XDcam EX native MP4 footage that was shot HQ 1440x1080i. Didn't show red render line in PRemiere so I believe the new sequence settings are correct (XDcam HD, 1080i (60i), 1440x1080, HD anamorphic 1.333, 29.97). In Premiere the footage looks supberb, I just had to interpret footage as HD 1080 anamorphic in the Premiere bin so it displayed to the right aspect ratio.
When I export with Media Encoder I find it looks compressed (softer) and on pans is blurs a bit with what looks like scan lines. Motion stabilizer was shot off when I shot, so thats not the issue. How do I get my HD project to encode to mpg2 and still retain the HD qualities. I've tried so many setting combinations in Encoder. Here's an example:
HDTV 1080p 29.97
NTSC
quality 5
1440x1080
29.97fps
none (progressive)
wide 16:9 (1.333)
profile: main
level: high
bitrate: min. 8.33, target 15, max 18.5
160 MB file size (sample 1 min 30 second clip)
What is the recommended bit rate that most people can play back on their computers / DVD player? Is it just not possible to get the quality unless you go BlueRay? What am I doing wrong? Is encoder improved in CS5?
Or should I be recommending a different playback format to clients?
I'm lost and can't find the answers. Thanks,
Christine Z

Christine,
You are getting very mixed up here or at least the language of your post is confusing.
Regardless of what flavour of HD you shoot and edit in, compressing for SD DVD involves resizing and effectively 'downrezzing' your footage so it will never look as good as HD. In PAL land where I live SD DVD is 720*576, NTSC is I believe 720*480. So to compress something to watch on a DVD player you want to be using those dimensions to begin with - there is probably a DVD preset that does that.
If, instead, you are talking about delivering to the client as some other file such as H.264, Flash or WMV then I would still down rez just to make it playback better - a 1440*1080 WMV wont play nicely on most PCs.
The settings you state below, by the way, look more like those you'd use for HD DVD or Blu-Ray.
In terms of using the Media Encoder in CS4, if it's any consolation, I've never got a decent HD to SD conversion out of it.
Finally the quality of DVD or other file playback can vary enormously depending on the monitor so check it on a couple of others and if it's a DVD, try it on a TV.
Maybe post exactly what you're trying to achieve and I'm sure others will chip in.

Filling of set up tables for Full and Delta updates

Dear Gurus,
How do I go about filling the set up tables if I want to load historical data to BW using LO **** pit when set up table is running on delta ?
I want to know how many set up tables will be there for each data source, Because if set up table is running on delta and using the same table I want to load historical data also then will I have to delete and fill set up tables or there will be a separate set up table for full upload and delta ?
If we have multiple set up tables for one data source then in the T-code OLI*Bw, where * -> App logistics num, so to fill I just say OLI6BW, then which set up table it is going to refer.
Clarify my doubt and get rewarded with plenty of points.
Regards
Mohan

Hi,
Filling up the set up tables depends on the datasource.
there are different T-codes for the respective extract structures
OLIIBW transaction PM data
OLI1BW INVCO Stat. Setup: Material Movemts
OLI2BW INVCO Stat. Setup: Stor. Loc. Stocks
OLI3BW Reorg.PURCHIS BW Extract Structures
OLI4BW Reorg. PPIS Extract Structures
OLI7BW Reorg. of VIS Extr. Struct.: Order
OLI8BW Reorg. VIS Extr. Str.: Delivery
OLI9BW Reorg. VIS Extr. Str.: Invoices
OLIABW Setup: BW agency business
OLIFBW Reorg. Rep. Manuf. Extr. Structs
OLIIBW Reorg. of PM Info System for BW
OLIQBW QM Infosystem Reorganization for BW
OLISBW Reorg. of CS Info System for BW
OLIZBW INVCO Setup: Invoice Verification
OLI7BW is the tcode for Sales Order.
Hope this solves Ur issue....

Why won't Apple provide a list of COMPATIBLE SET TOP DVD PLAYERS?

Why won't Apple provide its users a comprehensive list of COMPATIBLE DVD SET TOP PLAYERS? If they have, can someone direct me (us) to it? Although most set top DVD players will read Apple burned DVD discs, many set top DVD players will NOT read DVD's burned with the combination of iDVD and or DVD Studio Pro software and the built-in burners that ship with Mac computers. Obviously this is a third-party related issue, but it might be nice to provide at least the know set-top DVD players that DO WORK with DVD's burned on Apple computers using Apple software.

Although most set top DVD players will read Apple burned DVD discs, many set top DVD players will NOT read DVD's burned with the combination of iDVD and or DVD Studio Pro software and the built-in burners that ship with Mac computers
Blatantly untrue ... pure BULL. I've been burning DVDs for years with my Mac and DVD-SP. After thousands of DVDs delivered to clients, I've only had two (yes, 2) complaints of playback issues.
The two major factors to playback compatibility are the quality of the media and the bit rate used. Keep bit rates reasonable; don't use AIFF audio; use only good quality media like Verbatim or Taiyo Yuden and stay away from low quality media such as Memorex.

Sets of Radio buttons all grouped together

I am creating a form with many sets of radio buttons. Each set contains 3 buttons. When I add the 4th button, Designer groups it with the first three. When I add a 5th button, it is automatically grouped with the first 4. I need to separate the buttons into groups of 3. How do I manually choose which radio buttons to group together?
Eric

Doing this is little tricky... Add all your radio buttons and then choose all the ones you want to group in a different set holding Ctrl key. And then click your mouse button (right). Then choose 'Wrap in New Radio Button Group'.
Good luck,

N97 internet setting

can anyone please tell me what the internet setting are for my N97 im on at&t...tried automatic setup and it still doesnt work....please help

I actually read throught all the problems encountered on N97, but i am a little surprise that so many problems have pop up.
I did encounter a few resets myself, that was mostly on the first 3 days, while i was busy fiddling with the functions, including the internet call functions. i think on the fourth day, the phone wanted to do an update, and afterthat, its working without problems since.
I assume, after 4th day, i fiddle less, less load and changes, therefore the phone didnt give problem.But still, some of the problems listed in the fourm do exit, like after u have connected to the PC, the settings for the messages change back to C:.
i cannot be bother, and left it that way, after reading so much problems, i decided not to change too many setting.lol.
Meanwhile, its a good phone,except the need to get use to it again. NOKIA has changed so many folder names or removed them altogether, like the gallery is missing. now i have to re-learn what i know abt nokia for the last 10 years. Sad.
