How to minimize noise with 1127/1331 setup?

Hello,
I've correctly configured my 1127 multiplexer switch with the 1331 terminal block. I've attached BNC to 2-wire adapters through which I'm routing precisely controlled DC levels. My problem is that I'm getting emf noise with the signal and suspect that it's being coupled through the two-wire pairs at the 1331 terminal block.
Is there a terminal block that I may attach to the front of the 1127 that has coaxial (BNC or SMA) adapters so that I may minimize this source of noise? I note that the BNC2095 product is not explicitly compatable with my SCXI 1127.
Thanks if anyone knows anything or has successfully dealt with this issue.

Hi mkelley,
I've looked into this issue, and have some questions for you. What is the form factor that you need for this switch? Does the switch need to be SCXI, or do you have an available PXI slot for the switch? Are you using Switch Executive to make these routes?
It doesn't look like there is a BNC option for the 1127, however there may be other options for this cable type. The SCXI-1193 will give BNC connectivity for the matrix, using a MCX to BNC cable to connect the signal. I am confirming that this would be the correct option for you, as the SCXI-1193 matrix configuration will be a sparse matrix. I will follow up with you when I have more information.

How can we achive active/active cluster setup with Oracle

Hi Experts,
How can we achieve active/active database setup with oracle WITHOUT USING RAC.. As far as I know it's impossible (unless I'm wrong)..
We are using Oracle 11.2.0.1 64bit on Windows 2008 server. We deployed Oracle FailSafe but that's more of an active/passive solution based on a windows cluster.
The other solution we were thinking about is to use DataGuard and replication.. two servers.. the oracle instance running on one server generating logs, and the other server receive the logs and apply them to the physical standby db.. Still, this is not a real active/active setup.
So, is it possible to run 2 servers in an active/active cluster and have the oracle database in an active/active setup or have the instance running on multiple nodes (at the same time)?
Thanks

Let me give you a brief explanation of what the situation is and you can be the judge..
My client have four databases with the smallest one being 20GB and the biggest around the 35gb (SGA 750mb to 1.4gb (Tiny by DB standards) and probably on a normal day, you can run all four of them on a decent desktop).. The DBs are used to keep track of people information. Through out the year, the databases are almost sitting idle, and by idle I mean, the odd update here and there, the odd report..etc. No hard real processing of any sort. Two days of the year (end of year) we have all the operators consolidating records and what's not and they will be pounding away entering data and updating the tables - with hourly reports that goes to 3rd parties. The client expects a 99.99 up time and availability during those 2 days.
Now, tell me, How can I justify using RAC and spending hundreds of thousands of dollars in licensing and what ever extra costs introduced by the complexity of the environment for the above scenario knowing that I don't have any real use for RAC for 363 days of the year; and we MIGHT need it for 2 days of the year? This is the dilemma we're facing.
Thanks

How to minimize Final Cut pro with one click?

I know you can minimize windows (canvas, timeline, etc) by pressing Command+M 4 times but how to minimize Final Cut pro with one click?

Hold down the Option key and click the Minimize button on any window, all windows in the app will minimize.
Don't know what or if the reverse of this is - so although it's a one click minimize all windows, I believe you have to re-enlarge them one at a time.

pdf file is too big (7MB). Need a pdf file with max size 4MB. How to minimize the size of a pdf file?

The other alternative is the Save As Other>Reduce File Size. The PDF Optimizer gives you more control. You might also use the audit feature in the PDF Optimizer to see where the size problem is coming from. You might find that in the WORD file you can select and image and then go to the FORMAT (pictures) menu and select compress for all of the bitmaps in the file. That will typically use 150 dpi by default that is adequate for most needs.

JimHess~ Many thanks. In my short history with LR, it's amazing how many people I've seen ask this question. I'm nearly embarrassed at how simple the fix was, but grateful that you didn't dismiss such a basic question. You made my week. And my friend's photo album...

How do I deal with constant "error loading content" messages?

I'm constantly seeing error messages on my Apple TV (2nd gen) on content I easily watch on my other iDevices. What gives? This thing is rapidly becoming a vy expensive paper weight. Possibly the worst Apple product I've yet purchased. Am I alone in this? What can I do?

You cannot connect to TC using USB.
Plug the TC into the computer using ethernet.
Press and hold the reset button on the TC for about 10sec.. until front led rapidly flashes.. release it.
Open the airport utility and make sure you can locate the TC. Check the disk page that the disk started up without errors.

If TM still cannot find the TC disk.. reset TM and redo the setup.

Problem with Audio MIDI Setup using multiple accounts

I'm having a problem with Audio MIDI Setup recognizing all of the MIDI devices on a G4 Tower with a non-administrator account. The main administrator account has no problem seeing anything, but the non-admin account won't see anything. Does it all have to be added in manually, or is there a preferences file to copy over that will take care of this. Failing that, is it a problem with file permissions? Any help would be greatly appreciated.

Don't know whether this of any help, but there's an identifiable issue with AMS and Digital Performer 5 where DP5 simply won't load with AMS setups configured with previous versions of DP. Which is probably irrelevant to your problem, but ...
What I and other DP users have found we have to do is start with a completely new, blank AMS setup, and reconfigure our devices from scratch, and although this was kind of hit and miss and on the fly (don't really understand what the the issue was, exactly), I think the bottom line was if we used the new AMS setup with DP5 before anything else that might cause its data tables to change, we were ok.
So if you can do it, it might be worth setting AMS to a new blank template, then connecting your interfaces, see how far you get. And always make sure you've got the latest drivers of course, though I'm sure you've done that.
Never used Mbox or 410, but I've an Ozonic which I think uses the same M-Audio firewire drivers as the 410, and don't have any problem with that, FWIW.

How to minimize Client-Server Round-trip in ADF Faces application ?

Hi All,
We have just finished POC on our prototype of ADF Faces + ADF BC application. The POC Emphasizes on Bandwidth requirement.
After receing the result from the communication provider, including : TCP packets send, Bytes sent from/to server and number of Client-Server Round-Trip.
There are several part of the application that Must be tuned for the application to run on acceptable performance.
Here is some page/ function that should be tuned :
- First page, ADF Read Only Table with two images and some buttons, cause 5 round-trip
- ADF Dialog Returning Value (as LOV), cause 4 Round-trips
- On ADF Form, press Commit button, cause 3 Round-trips.
So the question is :
1) How to reduce round-trips on ADF Faces application ?
2) How to minimize the bytes send from / To server on a specific user action ?
Please give me some recommendation..
Thank you very much,
xtanto

Hi Frank and Steve,
Thank you for your reply.
Yes Frank, what I mean by Round-Trip is the traffic between Client and the Server. And Yes, we will use VSAT where the latency is 1 - 1.5 second, so that round-trip matters significantly.
What I will do is :
- use minimal skin and No image at all
- don't use Dialog for LOV because it requires AutoSubmit there.
- Use 'Apply-Changes' button to do server-side validation before Commit.
Then do the POC / testing again.
Thank you,
xtanto

Internal computer noise with firewire audio devices

Hello
I have a Power Mac G5 PPC 2.3 and Mac Os X 10.5.6, with tiger I have the same problem too, I bougnt my Mac for audio work, and from the purchase day, I have the same problem, I bought my first audio sound card, M-Audio Firewire 1814, and I installed the last drivers for my operating system, when I start Logic I must go to prefferences audio and select the device, I select coreaudio tab and M-Audio Firewire 1814, and when I click on apply changes, in the Mac start an internal noise, low level, and hign frecuency, and this sound keep while logic is open or another audio aplication with M-Audio 1814 is selected like audio device like Pro Tools M-Powered.
Aplications work fine but this noise I think is a conflict with audio device drivers, I can hear this sound too when I go Aplications/Utilities/Audio Midi Setup/ and in the audio devices tab the internal noise not is sounding but when I click on Midi devices tab, the internal noise start and is sounding while Audio Midi Setup is Open, if I quit Audio Midi Setup the noise stop.
In the Activity monitor I can read MIDI Server process is launched when I click on MIDI Tab, and if I select and close this process the noise stop.
It is only for the noise when is sounding with audio midi setup, close MIDI Server and noise stop, but when the noise is with any application (Logic or Pro Tools) in the activity monitor quit MIDI Server process but the noise keep sounding.
I have Digi 003 Rack and Pro Tools LE too, and I have the same problem when Pro Tools LE start.
If I select M-Audio 1814 in system prefferences/Audio, like audio device and open ITunes the noise is not sounding with ITunes, I can listen music whithout problems, but If I select Digi 003 Rack like Audio Device in
System Prefferences/Audio The noise is sounding with ITunes start becouse Digi Core Audio Driver is launched.
I think is a conflict between Thirty Parts Drivers and The System but I need help, what can I do to resolve this.
Thanks

Nope, someone elsewhere suggested a thing called "ground loop" occurring. Meaning, the interference from the electric current. They suggested trying it with battery power (power detached), and without. But at least for me, made no difference unfortunately.

HOW to Minimize Screen Size in Screen Painter

HI all,
I am developing one module pol program for material transfer.

and after cliking the push button on it i will see the normal screen.
how can i show screen as dialog box. or how to minimize the screen size to look like dialog box.
please do the need ful.
points will be rewarded.
thanks
vinod

hi
good
While calling you will use like this..
Calling a single screen is a special case of embedding a screen sequence. If you want to prevent the called screen from covering the current screen completely, you can use the CALL SCREEN statement with the STARTING AT and ENDING AT options:
CALL SCREEN <scrn>
STARTING AT <X1> <Y1>
ENDING AT <X2> <Y2>.
This calls the screen number <scrn> as a modal dialog box. When the screen is displayed, the screen that had called it is visible but inactive. The STARTING AT and ENDING AT additions specify the top left-hand and bottom right-hand corners of the dialog box respectively. In the screen attributes of screen <scrn>, you must set the Modal dialog box attribute. This defines how the interface elements are positioned on the screen.
thanks

Ubuntu with Snow Leopard Setup?

I am using a Mac Mini as my home server using Snow Leopard for AppleTV and printing
I Bootcamped the disk and installed Ubuntu.
I can boot either OS and run them with no problem.
I want Lion Server and Ubuntu on the same disk with the option to boot one or the other. I have Lion server on an iMac as the display for the mini. No problems.
Disk utility on the Mini will not let me change partition per Article: TS3926.
It shows the following partition structure:
DISKOS1 about 200MB
Macintosh HD at 99GB
UBUNTU at 9.02BG
DISKOS4 at 108.37 MB (funny DU shows GB on it, but it is MB)
I don't how I ended up with the above structure. It started as Sno Leopard. I ran Boot Camp to create the Windows partition and I installed Ubuntu.
What is the proper order and procedure to have a correct Lion install with Ununtu as an alternate boot?
I tried this once on the iMac and lost the Lion recovery partition in the process. I ended up reformatting and resinstalling to get it right. I want to leave the iMac a clean Lion Server install. I want to dual boot the Mini. I may then want to virtualize the mini if possible. It has 4GB RAM.
Is there a better approach?
Should I give up and keep Ubuntu on an external disk?
Thanks

Having spent some time getting a triple boot working on my MacBook Pro, I think the only option left to you is to reinstall windows. If you installed grub in the MBR for the Windows partition then you will need to reinstall windows in order to fix its MBR. As for Linux. You may be able to save that install by reinstalling grub in that partition.
Here is the link I used to setup my triple boot:

One of these links may help you with the grub reinstall. Good luck!

How to make "Utility" button in Printer Setup Utility available

There, i add a printer in the Printer Setup Utility and select it. i want to open printer utility, but the "Utility"
button in Printer Setup Utility is dimmed. In addition,
"Printer\Configure printer" in the Printer Setup Utility menu is also dimmed.
How to make "Utility" button in Printer Setup Utility available?
Thanks in advance.

Hi Jiong,
That button is to acess the printer utility for that particular printer, not all printers come with a utility. If you have the disk that came with your printer, you can see if it has a Macintosh driver, if it does then it mimght have the utility with it. It's pretty hard to run the utility on its own, its burried somewhere in the system so that's why you have that menu item. You can alternatively go on the internet and download the latest driver, which might have a utility. All the utility will do will give you options to check nozzle patterns, alighnement, ink tank levels, and cleaning options - just mimnor maintenence junk, non-essentials, etc. I think Tiger just comes with a whole heap of generic drivers for different printer lines, can't say for sure.
I wouldn't worry about it, especially if you have a relatively old printer.
Hope that helps
DKR
