Parallelism Redistribution documentation

Hello everybody,
I have 2 different question,
first one is about, intra and inter parallelism. I've read a lot of these two and wanted to clarify what I've learned.
intra parallelism is creating parallel processes and doing the job (like full table scan) by using these processes. Intra parallelism is used when there is not enough resource to make inter parallelism OR when there is just one operation which can be parallelised.
inter parallelism is, in my operation which I parallelised, there are 2 or more different operation that can be parallelised like a "full table scan" and an "order by". in this case whatever my DOP is, if there are enough resources oracle multiplies DOP by twice and first group does "full table scan" (producer) and second group does "order by" (consumer).
are these correct ? this is for clarification.
secondly, now I am trying to understand "redistribution methods". as I read, "redistribution methods" means communication type of between Consumer and Producer sets, how they will communicate and send rows to each other. (please warn me if something is wrong about that)
there are methods like, BROADCAST, RANDOM, ORDER, HASH, PARTITION, ROUND ROBIN, RANGE etc... I want to understand basic differences between them and I looked for but couldn't find correct oracle documentation about these methods, which document explain these methods ? there some info on that link:
http://download.oracle.com/docs/cd/E14072_01/server.112/e10837/parallel.htm#VLDBG1531,
but that document doesn't cover all distribution methods and their differences.
thanks a lot.

http://download.oracle.com/docs/cd/E11882_01/server.112/e16541/parallel002.htm#i1010979
at this link, looking as the "figure" and some more links that I googled, I concluded this meanings about inter and intra parallelism.
and the things about distribution methods I've wrote, is from Oracle university 11g Datawarehouse administrator documentation, parallelism chapter (chapter 4).
and I dont understand how these info will lead you about helping me about my questions ?

Installation Help - From 1.3 Beta to 2.0 to 2.1

MacBook Pro under Leopard (10.5.2)
I had installed BootCamp beta while running Leopard and am currently at 1.3 Beta.
I am unable to install the 2.1 update (and have read the long thread also on this board).
I have been running Parallels as well which I installed after I had installed Bootcamp allowing me either to boot into Boot Camp or run Parallels.
Documentation indicates that I could insert my Leopard disk to update to Boot Camp 2.0 but after booting in XP SP2, the Boot Camp driver installation does not start automatically nor can Windows find the setup.exe file on the Leopard disk.
I obviously cannot update to Boot Camp 2.1 without 2.0 and just am stymied at this point. Would rather not have to delete the partition and start all over again with the installation of my Windows apps and data.
Any help would be appreciated.

Thanks. MacDrive was the issue. All updated first to 2.0 and then to 2.1
I'm embarrassed because as a columnist I don't usually miss these things. That one went totally by me.

Impdp is very slow

Hi Experts
i need ur help..actualy i daily use to impdp to resotr schema backup from one DB to another.. but today impdp process is writing very very slow..my DB version is 10gr2 (10.2.0.4) and charecter set is same of both source and target db.... what is the possible reason for this attitue of impdp

You are sure your environment can handle this degree of parallelism? Too high degree of parallelism could be worse than no parallelism, form documentation:
Controlling Resource Consumption
The Data Pump Export and Import utilities enable you to dynamically increase and decrease resource consumption for each job. This is done using the PARALLEL parameter to specify a degree of parallelism for the job. (The PARALLEL parameter is the only tuning parameter that is specific to Data Pump.) For maximum throughput, do not set PARALLEL to much more than twice the number of CPUs (two workers for each CPU).
As you increase the degree of parallelism, CPU usage, memory consumption, and I/O bandwidth usage also increase. You must ensure that adequate amounts of these resources are available. If necessary, you can distribute files across different disk devices or channels to get the needed I/O bandwidth.
To maximize parallelism, you must supply at least one file for each degree of parallelism. The simplest way of doing this is to use wild cards in your file names (for example, file%u.dmp). However, depending upon your disk set up (for example, simple, non-striped disks), you might not want to put all dump files on one device. In this case, it is best to specify multiple wildcarded file names, with each in a separate directory resolving to a separate disk. Even with fast CPUs and fast disks, the path between the CPU and the disk may be the constraining factor in the amount of parallelism that can be sustained.

Location of Parameter File (pfile)

Hello,
I like to know, does Oracle stores the location of Parameter file (pfile) in any of the object?
Thanks
Sameer

Yes if you use the Oracle Parallel server option.
By default an instance will start a database in exclusive mode and no other instance will be able to attach to the database.
To start multiple instances on the same db you need to start them in parallel:
startup pfile=$ORACLE_BASE/admin/sid1/initsid1.ora PARALLEL
then after changing your ORACLE_SID:
startup pfile=$ORACLE_BASE/admin/sid2/initsid2.ora PARALLEL
Note: There is actually alot more involved then this. See the Oracle Parallel Server documentation for your version at http://tahiti.oracle.com

Help needed connecting iPhone 5c to Windows 8.1 using Parallels 10 on Mac

I cannot for the life of me figure out how to get my iPhone to be recognized on my virtual machine- Windows 8.1 via Parallels 10. I have read this documentation and keep getting dead ends iPhone, iPad, or iPod touch not recognized in iTunes for Windows - Apple Support .
IPhone is recognized perfectly by iTunes in OS X, so I know my cable is good at least.
Any help in resolving this matter would be much appreciated.

According to the information I found on this HP support forum, it appears that the wireless card is 2.4GHZ only. I'll let you read on it. http://h30434.www3.hp.com/t5/Wireless-Internet-Home-Networking/hp-15-e050sa-5-GH z-Wireless-enabled/td-p/3448679

QT Pro -- Did I miss something in the documentation?

Someone please check me on this, because I think I must be getting senile. After many years of thinking about it, I finally popped the whopping $30 for Quicktime Pro (for QTP7 on my 27" iMac Core 2 Duo, OS X 10.6.7). It installed without problem -- though it's rather disconcerting that it still looks, smells, and largely acts like QT Player 7. I had a no-fun-at-all-time trying to open video clips that wouldn't open with the In and Out selection markers, so I couldn't trim, or cut and paste, or do anything at all to edit them in a time-linear sense. I DL'd the QuickTime 7 User Guide PDF with the "Getting Started With QuickTime Pro" PDF and read it and re-read it several times, tried QT Pro help, but I couldn't find a single bit of information on why some video formats would open with the In and Out selection markers, and thus be editable, and others would not.
After 2 solid days of knocking my thick skull against the wall, I finally had my Archimedean Eureka Moment, and realized that ALL the files that WOULD open with the In and Out selection markers were .mov files, while files I was trying to open unsuccessfully were .mpg, .mpeg, m2v, .mp2, mp3, .mp4s, and suchlike. I went back through the QuickTime 7 User Guide PDF AND QuickTime Pro Help, as well as searching here on Apple's support forum, and on other Apple/QT discussion groups, and NOWHERE could I find anything that said files had to be in .mov format to be editable with the In and Out selection markers. Can someone please point out to me the pertinent section of the documentation I must have missed, where that MOST important information is presented.
In a Hail Mary guess, I thought that perhaps the "QuickTime MPEG-2 Playback Component for Mac OS X" might help solve my problems, though it's description didn't sound that promising: "This add-on to QuickTime or QuickTime Pro provides the ability to import and play back MPEG-2 content, including both multiplexed (also known as muxed, where the audio and video tracks are interleaved together into one track) and non-multiplexed (also known as elementary) streams." Yeah, I got that, but does it do anything ELSE in QT Pro, like give the user the ability to edit.mpeg video with the In and Out selection markers in QuickTime Pro? I could not find THAT information either, and I'm really not keen on plunking down another 20 bucks for a function as simple as playing back .mpeg files, when I have several utilities that already allow me to do that.
What I'm using QT Pro for right now is chopping up free, non-commercial,non-copyrighted or copy-protected, legally-belonging-to-me, guitar lessons so I can break them down into small sections at a time that I can loop and learn before going on to the next section of the lesson -- very handy. So, I'm sorry, but I don't really think I'm a candidate for the thousand-dollar Final Cut Studio, or even the two-hundred dollar Final Cut Express. I'm retired, and on a fixed income, and I can only afford what I can afford.
So PLEASE, someone tell me if I'm stuck with no choice but to convert my videos to .mov format before I can edit them in QT Pro, or have I, in my dotage, overlooked another, cost-free way, of actually using QT Pro for what I want to do, without all the monkey-motion of converting everything.
Thanks for your time,
Bart Brown

I may or may not need QT Pro (a moot point, as I already have it)
As previously indicated, hang onto it if you plan to do any layering, masking, and/or picture-in-picture video composites. It is handy for quick clip modifications not requiring use of a full video editor.
I DO need the $20 MPEG-2 component (nickel & dime, nickel & dime, nickel & dime, nickel & dime)
I HAVE FFMPEG X
I HAVE MPEG Streamclip
The Apple MPEG-2 Playback component is only needed if you plan to use MPEG-2/M2V content in QT based applications. That is, applications like QT and MPEG Streamclip which access codecs for which your system is configured. Utilities like FFmpegX, VLC, and HandBrake have their own codecs embedded within their respective applications.
In regards to MPEG Streamclip (and AC3)...
Rather than try to cover each individual point as you brought them up, let me summarize the situation by enumerating your options.
1) The Apple QT MPEG-2 Playback component does not support any audio compression formats. It is a video codec only just as H.264 is a video codec. Either the audio is QT compatible or it is not. If it is not, then your best option is to convert non-compatible audio to a QT compatible compression format.
2) If you really want to play AC3 DD5.1 audio on a Mac, the best way is to use the VLC media player and send the AC3 audio data to an external DD5.1 decoder via the VLC "passthrough" option. (I use the Logitech Z-680 for external decoding and amplification of optical digital or 6-channel analog data.)
3) No matter what AC3 codec you install on your Mac, for it to work on the Mac, the audio will either have to be mixed down to two channels for core audio processing on the system or you will have to install an auxiliary audio card capable of outputting the AC3 decoded audio as 6 separate channels of audio which can also be handled by the core audio system software. (I use a 6-channel M-Audio card here for audio usually transcoded to either 4, 5, or 6 channels of AAC or AIFF compressed audio data.)
4) While MPEG Streamclip only supports 2 of the 6 DD5.1 channels at a time as QT compatible audio channels at a time, the user can select which two channels are output. Most users opt for the "stereo mix" option but could just as easily select the "Front Mix", "Surround", "L/R Ch.", "Center Ch.", "LS/RS Ch.", or "LFE Ch." option. You can even make multiple passes to decode/export all 6 channels of audio and attempt to re-assemble them as separate audio tracks, 3 paired stereo tracks, or a single "surround" audio track if you have the required hardware support for playback.
Anyway, I've DL'd my AC3, I'm buying my MPEG-2 component (which I still think is a ripoff: why leave out ONE critical component -- when you've included dozens of others for free -- and make your customers pay, AGAIN, to make the $30 software you just paid for from the same company into a $50 software package so it will do what you want it to do? To me, that dog don't hunt).
As has been stated many times, QT is based on the idea that multiple parallel tracks of data (up to 99) can all be played back synchronously using a single external clock. Multiplexed MPEG-1/2 content, on the other hand, employs spatial synchronization—two different technological approaches. By interspersing blocks of audio data between blocks of video data in a single data stream, one form of data is prevented from "overrunning" the other. AVI works in a similar manner using parallel tracks of data. Only in this case, frames of audio data are interleaved with frames video data to maintain synchronization. The main difference here, however, is that, as far as QT is concerned, the frames are only a half frame "out of sync" while the MPEG-1/2 data is "out of sync" by an undetermined degree. Since QT cannot equate a specific time reference to corresponding frames of audio and video content, it cannot properly convert or edit this content. In short, the MPEG-2 Playback component is not a "critical" component since QT was never designed to use it and only added it in response to user requests. As to pricing, If you wish to perform transcoding of WMV content, the Flip4Mac codecs alone run from $29 to $179 depending on what level of capabilities you require. (And you still need the QT 7 Pro key.) Your main problem here is that you are editing in an QT non-compatible compression format designed for content delivery rather using a QT compatible, edit specific compression format. I assume this was a result of have the Tape-DVD recording device on hand and decided this approach was easier than going the more conventional route of converting to DV using a DAC device. As a result, your data is probably compressed to about 1/5 the data rate/size of a DV file. Unfortunately, you will likely have to pay a price in terms of quality and work flow problems. Still, I suspect you would be less than willing to go back to square one with your tapes and re-digitize the content a second time.
What MORE am I going to need to accomplish that, do you know?
Whether you are editing a "muxed" MPEG-2/AC3 file or a DVD title consisting of one or more VOB files (also containing "muxed" MPEG-2/AC3 content), the work flow is essentially the same. Simply drop all of the non-zero VOB files in the title set to the MPEG Streamclip work window, fix the timecode breaks, and start your editing as if you were working with a single MPEG file.
NOTE: unless it has changed, FFmpegX may still be limited to 2 GB MPEG file sizes for processing while I believe MPEG Streamclip has a 4 GB MPEG file size limit. I assume this may not be a problem for you if you are working with "snippets" but could be a problem if edits are merged to overly long files. In either case, the VOBs are encoded to files of 1 GB or less and should not present a problem even if you are working with a multi-VOB title set.
why do I have to go through the kludge of recording tape to DVD, then sneaker-netting the DVD to my iMac to get the digitized video on my computer?
You don't. You could have used any analog-to-digital converter device. For instance, many old Hi-8/Digital-8 camcorders and most recent DV camcorders have the ability to convert your VHS output directly to DV content which can be captured in any video editing (e.g., iMovie), dedicated capture (e.g., the free Vidi app) or even QT X/QT 7 Pro applications. The content is digitized in real time to your computer. Files would probably be 4-5 times larger than your DVD or MPEG files, but the resulting quality (depending on the original tape quality) might be better and the content is fully compatible will all QT apps (assuming you don't somehow corrupt the files).
On the other hand, if I already had all of those DVDs on hand, I might consider using HandBrake to convert them to H.264/AAC files and then simply trim and merge the resulting files for distribution. I.e., Handbrake includes its own embedded codecs and is capable of batch processing files while you sleep or are busily engaged in other activities. And, the resulting files are editable at the frame level in the QT 7 Pro which you already have.
Why is it that Mini Port on the new iMacs is unable to take direct HDMI INPUT from a digital video source at 1080p natively? It's pretty depressing A) having, once again, to buy some $130 adapter to even GET digital input into the 27" iMac, and B) even if you CAN get digital input, being limited to 720p (Belkin AV360™ Mini DisplayPort Converter for 27" iMac. Belkin's description: Accepts full 1080p signal, provides 720p to iMac) on a 2560 x 1440 display.
You would have to ask Apple. My guess is that they don't want to get involved in HDCP support issues and besides, previously this port has been limited to output only and is still described as such on the Apple Store Tech Specs web page.
As I'm nearly 63 years old, I'm absolutely gobsmacked at the progress in computer technology from my first Sinclair Z80 to my Amiga 1000 to my first Mac -- a IIci ($5000!), to now, but I thought the whole idea was to make things easier.
Still have a few years on you. (Let's just say I'm on the high side of 65 and leave it at that.) I started with the Polymorphic 88, System 16 (S-100, 8080 processor with all of 16 K of memory) and worked my way through an Apple //, Mac 128K, Mac IIci, 8500AV, two G4s, a PPC G5, and am now on my first Intel Core Duo laptop. (The last five are still "in service" and the Poly-88 is somewhere in the storage shed.) They say that a program expands to occupy the memory available to contain it. In a similar manner, as things become "easier," we tend to expand our horizons into more difficult fields of endeavor.
Do you know of a good place to start to try to learn about this stuff?
Normally in a case like this, I would recommend you contact your local Mac/Apple User Group and see if they have an active Video SIG. By discussing your goals and available hardware/software, they may be able to find a work flow that meets your needs, minimizes your investment in time and effort, and avoids the need to purchase anything additional. For instance, is it your intention to post media on the internet, archive it for future editing purposes, distribute it to immediate friends and/or relatives, what is more important—time or quality of your content, what do you mean by "clean up," etc? These are likely the questions that will determine which work flows best suits your needs and in which order they should be applied.

Open VI Reference prevents execution of other parallel threads

I am using splash screen to start an application. I use dynamic loading of the Main.vi and an animation during the loading, both in parallel threads (see image below). However, when the Open VI reference VI is called everything else stops executing (the animation stops running) until the Open VI reference is done. I must call the Main.vi dynamically, because it takes some time to load and I want to notify a user that the application is loading (using animation). Is there an option to prevent the Open VI reference to block the execution of other threads? Or should I use some other approach?

andrej wrote:
But the problem is not in the Run.VI method because the Open VI Reference blocks the execution of the top loop and I need the Open VI Reference to call the Get VI Dependencies method. Other approach could be to create a static array of dependencies and then to use this array to load VIs from bottom up.
The only question now is if the Get VI Dependencies method returns dependencies in top to bottom order? If it does then I can just load VIs in reverse order from the array.
Well the problem is the Open VI Reference! This executes in the UI thread, as several people have explained already (and really can't be made to do otherwise without causing a number of possible and nasty race conditions, some of them even related to the underlaying OS and not just LabVIEW itself), just as your two Property Nodes in the upper loop have to use the UI thread too.
Once Open VI starts it only returns if it has loaded the required VI fully into memory (and that includes any dependencies that aren't already in memory) and linked them all properly together or runs into an error during loading. For this duration, NO UI Property Node can execute, which is what stalls your upper loop. If you would use local variables or terminals instead the upper loop would happily run along while Run VI loads the entire VI hierarchy but it would still not show on the UI, because in order to draw the new data from the diagram passed to locals and terminals LabVIEW has to catch the UI thread to do the UI drawing.
So first fix is to kick out any property nodes from the upper loop and the second part of the solution is to load your VI hierarchy in chunks instead of simply loading only the top level VI directly. It would be nice if Open VI had an option to allow UI thread release between loading of chunks of VIs, but the implications are not that nice. It would be quite easy for an uncareful LabVIEW programmer to create a lockout situtation then, where two functions are in fact waiting on each other to release some locks so that the program gets hang up. And a simple warning in the documentation to watchout as this option can allow to create such lockout situations is not very useful as nobody reads them anyhow.

11g Parallel Execution on AIX 6 - SMT Enabled or Disabled?

Greetings,
I've had no luck searching for an answer to this question and I'm hoping someone can answer it:
Can Oracle 11g Parallel Execution spread the "granules" of paralllism across the threads (logical cpus) in an AIX SMT enabled environment, or should SMT be disabled and the "granules" be spread scross the processors (virtual cpus)? The application is a data warehouse in a non-RAC configuration using a p570 server. From what I've read, the server must be SMP for Oracle parallel execution capabilities to be maximized, but I think all AIX servers are SMP (not sure if the server needs to be ordered as an SMP server). I'm mostly concerned with the data load processing at this point, and not so concerned for the query right now. I believe AIX 6.1 can enable/disable SMT dynamically. So would it make sense to disable during data loads, and enable for DSS query?
Hope the question makes sense. Thanks for any help in advance!

SMT will determine Oracle's cpu_count parameter.
However this is a static parameter.
So it won't work, and it might be even dangerous to change it on the fly.

Just coming from Win and need Help with bootcamp/parallels+general osx stuf

Well I absolutely love my Mac. I'm just having some problems affording it financially, but when I compare this new MacBook Pro to other like computers, there's a very very small difference in the hardware, and Im usually building laptops that are similiar to this for around 2k anyways. So I'm not 100% sure if I'll keep this or not, and maybe settle for cheaper PC that's under 1.5k (because Apple charges you a 10% open box fee) and buy a mac when I'm in a better position, or just keep this and see what I can do.
But a few of the things that are making me miss a PC might push me toward a cheaper PC. And so maybe someone here can help me out before I make a decision.
First off, is there anything that's the equivalent to a disk defragmentor for OSX?
Second, is the graphics card really powerful in this Macbook 15 inch 2.4 ghz (the newest one)
Im also having a problem with this keyboard and my favorite game. Basically I need to hold down certain keys (control, alt, shift and space) in order to use skills. But for some reason when I hold down any of these buttons, it only reads it once. So I have to push it every time I'd say, want to heal myself or hit a monster... and that might not seem like a lot but if you play a game for 1 hour + (I'd usually play around 4 hours) it's going to absolutely kill my fingers and make playing the game take a lot longer.
Now I'm using parallels (the only way to play my game) and whenever I try to install a new KB, because I've found out that the way a KB is wired will determine whether or not you can spam a key or not (Like a cheap USB one wont work, but a more expensive logitech one allows you to) but it either
1) Crashes Parallels and my Win VM
or
2) It sets up whatever kb I use to be used with Mac OSX's drivers which means no matter what the KB is, ctrl alt space and shift cant be spammed.
I'm also unable to use FRAPS, a PC video capturing program used for games while running parallels. My FPS constantly dips to 0 which lags me in the game, and I can't find a good recording program thats OSX side and that works while Parallels is running (I emailed parallels about what vid they used in their demo but no response)
Now if use bootcamp, will I have nothing to worry about? Will all of the hardware act like it should act natively on a PC? As in will my nVidia graphics card act like it normally would on a PC instead of it being some kind of virtualized hardware or something like on parallels?
Thanks for the help guys... 2 weeks to decide on whether or not I keep th is laptop....

The graphics card is a higher performance GPU than the X1600 in the previous MBP models. As for "really powerful" you don't provide any basis for comparison. Visit the ATI site to find out the specifications for the model.
Well I understand that much. I just mean as far as a graphics card in general goes, is it strong enough to support a variety of games (both PC and Mac)? This is my first computer without a crappy intergrated graphics card which could barely handle games from the late 1990s.
As for keyboard shortcuts I'm not sure if you're referring a Mac or a PC game. However, this reference may help. If the game is a Mac version you'll need to contact the game's developer about any problems with how to use the game on a Mac. If you read the Parallels documentation it will explain how to generate any special keyboard characters when in Windows.
Umm it's not that. Like I first figured out this problem with all electronics in general when I was a kid playing with one of those press and speak books. What I found out was that, let's pretend there were 3 buttons. One was cow going moo, one was a cat meowing and one was a dog barking. If you held down the Cow button and pressed the Cat button, the cow would still Moo. If you held down the Cow and press the dog button, the cow would still moo. However if you pressed and held the cat button, then pressed the cow button the cat would stop meowing, and the moo would override it.
That same principle applies to keyboards from what I've seen. I know there are some keyboards where I can use the control button and the alt button at the same time, and some keyboard I can't use. I can't blame the game, because there ARE keyboards that work the way I want it to. And I'm not talking about keyboard shortcuts. Pressing Control+Alt isn't a shortcut in a game, just two different commands. Like one is jump, one is attack. In the game you can Jump and Attack with some keyboards, some keyboards only let you jump or attack.
Another example is if I put my jump key on the letter "a" and if I hold a, I jump over and over until I let go. but if I put jump to my space bar, I jump once then stop. For some reason it won't repeat keys while in a game. Same goes for other buttons, ctrl, shift, and alt.
Does that make things a little more clear?
but what I'm going to do is try my mac keyboard on a PC and see if it has the same limitations.
If Parallels is crashing either you have a faulty installation, your OS X installation is corrupted, or you have not allocated sufficient RAM for the VM. You need at least 2 GBs of installed RAM to use virtualization software and should allocate at least 384 MBs or RAM to Windows XP and 512 MBs to Vista. If you have only 1 GB of RAM installed your system won't be very stable when you try to run Parallels with Windows on 384 or 512 MBs of RAM.
I have the newest 15 inch which has gigs. And I've tried setting Parallels to both 1 and 512 (windows xp) and I worded the problem wrong. Parallels doesnt crash, parallels runs fine. What happens is Windows XP gets the blue screen of death whenever I try to install a usb device. Since I can't find a logitech keyboard that has drivers/software for a mac, I tried using a Windows one and tried installing it on my XP... and thats when I got the BSOD
Parallels uses all the native Mac hardware via the virtualization software. No special Mac drivers are required nor special Windows drivers.
If you cannot run a Windows program in Parallels it's not a problem with OS X. Complain to Parallels.
It's not that a program isn't running. It's running fine, it's just my FPS gets really low. What I'm trying to figure out is if my graphics card isn't good enough in general, or if it's not good enough to handle parallels and osx and a game with a video capture all at once.
Boot Camp runs Windows natively on the hardware just as if you were using any other dedicated Windows hardware. "Will I have nothing to worry about?" I don't know. Boot Camp provides the necessary Windows drivers for all currently produced Intel Macs. You can install Windows XP with Service Pak 2 or Vista. Read the Boot Camp documentation to find out more.
Well I meant will I have nothing to worry about as in, will my graphics card be as effective on my bootcamped win XP as it would be if it was a native XP laptop, or will it be slightly less effective since it was based for a mac intel computer... does that make sense or do I need to reword it?

Batch Test With Parallel TestSequences

Need a little assistance programming a TestStand batch sequence also containing test sequences which must run in parallel with synchronization.
I have a panel containing multiple UUT. Each UUT consist of 2 parts. The test may be divided into 4 groups:
1: Common start up test and programming
2a: Specific test and calibration on part 1
2b: Specific test and calibration on part 2
3: Common test and calibration of complete UUT
My application runs with the batch model (which I normally use and is familiar with), but must in this case also use parallel testing for each UUT. I need to be able to synchronize the parallel test sequences like they where running in normal batchmodel. I also need at some point to synchronize the to parallel sequences for all UUTs.
I’ve succeeded doing that with the enclosed sequence, but I am not sure it’s the right solution. Would like some comments.

A couple things regarding your issue:
You should be fine with just the Parallel or Batch model. Personally, if you don't need to switch out UUTs dynamically then I would go with the Batch model. Why? Because then you can use synchronized sections. Synchronized sections give you the ability to run a particular section of your sequence file (i.e. several or a single step) in Parallel, Sequentially or One Socket Only. With the parallel model you can kind of get there by using Locks and Queues. Look in the TestStand Reference Manual under Appendices A and B for more info on the Batch model and synchronized sections. To access the TestStand Reference Manual go to Start>>All Programs>>National Instruments>><TestStand>>>Documentation>>Manuals.
Regarding your VIs and how they would handle each socket. I don't think it's a good idea to make a different VI for each socket. Just have some sort of case inside the VI that if 3 comes in the set the right wires to populate your switching or COM functions. For instance: Lets say that Socket 1 is executing and comes to the step to call the com_port.vi. One of the parameters for that VI could be the socket number. Inside the VI you set the desired com port to read or write based on that parameter. You can set the parameter in TestStand by using RunState.TestSockets.MyIndex (that will return the socket you are on).
In fact you wouldn't even need the logic in your com_port.vi. I would assume that one of the parameters to that VI would be a VISA session to your COM ports. In TestStand you use the LabVIEWIOControl datatype which has property of DeviceName. If you set that parameter to be '"COM" + Str(RunState.TestSockets.MyIndex)' then you will achieve the same thing as passing COM3 if you were in TestSocket 3.
Anyhow, this is just a few ideas for you. Obviously you have to implement what makes sense.
Hope this helps,

Looking to run windows on my MBPro through Bootcamp or Parallels, but would like to use a downloaded Windows 7, is it possible to install without the Windows Disc?

Looking to run windows on my MBPro through Bootcamp or Parallels, but would like to use a downloaded Windows 7, is it possible to install without the Windows Disc?
Need to set up a workstation on my MBPro that will only run on Windows. Im willing to use Bootcamp or Parallels to see what works best. Need to get this set up this week to enable working from home on my MB - rural and hoping to buy Windows 7 online - am I able to get windows working through either bootcamp or Parallels without the actual Windows disc? Bootcamp set up guide calls for a disc.

Welcome to Apple Support Communities
First, the answer to your question is yes, it IS possible to install Windows in Parallels without a disc, using an .iso image file.
Boot Camp since OS X 10.8 also installs Windows without a disc: https://discussions.apple.com/thread/4889551?tstart=0
Parallels has complete documentation, series of forums, and a knowledgebase. You can also download the current release of Parallels 9 and try it for free for a few weeks before you decide to purchase it.
The Parallels Desktop for Mac product page: http://www.parallels.com/products/desktop/
The Desktop for Mac forums: http://forum.parallels.com/forumdisplay.php?58-Parallels-Desktop-for-Mac
Documentation: http://www.parallels.com/support/desktop-virtualization/desktop/#c12970
The Knowledgebase for Desktop for Mac: http://kb.parallels.com
The primary difference between a Boot Camp installation and a Parallels installation is that in the Boot Camp installation, you're installing Windows into a separate partition on your internal mass storage device (hard drive or SSD) and then rebooting your Mac directly into Windows.
In Parallels, you're always running OS X on the Mac and Parallels is running a Windows virtual machine.
Not to get too technical here, but it is also possible for Parallels to run an installed Windows Boot Camp partition as a virtual machine. If you're evaluating system performance with a trial copy, that might be the way to go, because you only have to install Windows once on Boot Camp as a dual-boot system, then install Parallels Desktop and run the Boot Camp partition as the virtual machine.
There is a performance difference between the two, with the Boot Camp Windows installation being faster, but without the convenience of running both Mac and Windows applications simultaneously offered by Parallels. Sometimes that convenience outweighs a performance hit.
I can't give you more Mavericks and Parallels 9 specifics, because I'm currently running Windows 7 with Parallels 7 on OS X 10.8.5. Parallels 7 will not run on OS X 10.9 Mavericks.
I've been using Parallels (to run a few old rarely-used WIndows applications with features that would require a steep learning curve and major expense to purchase and learn a similar Mac app) occasionally since Parallels 3 and Windows XP. With each new release of OS X, each new release of Parallels, and each new Windows release, there are ALWAYS 'early adopter' bugs that get worked out over time.

I operate MacBook Pro w latest version of OS Maverick. Also run Parallels with VM of XP. Bought Win 8.1 Pro w DVD. The DVD does't mount and eventually says the DVD is blank.

How do I get MacBook to recognize the DVD and permit Parallels to create a new Virtual Machine using the W 8.1 Pro DVD?

Question for Parallels documentation, forum, their own FAQ and Knowledge Base.
Even Windows on Mac support for Boot Camp has instructions, Boot Camp Assistant will create a flash drive (no one is using DVDs).

Parallel Processing in Oracle 10g

Dear Oracle Experts,
I would like to use the Parallel Processing feature on My production database running on Unix Box.
No: of CPU in each node is 8 and its RAC database
Before going for this option i would like to certain things regarding Parallel Processing.
1. According to my server specification how much DOP i can specify.
2. Which option for Setting Parallel is good
a. Using the 'alter table A parallel 4' or passing the parallel hints in the sql statements
3. We have a batch processing jobs which are loading data into the tables from flat files (24*7) using sql loader. is it possible to parallel this operation and any negative effect if enabled parallel.
4. Query or DML - which one will be perform best with parallel option.
5. What are the negative issue if parallel option is enabled.
6. what are the things to be taken care while enabling the parallel option.
Thanks in Advance

Hi,
first of all, you should read [Using Parallel Execution|http://download.oracle.com/docs/cd/B19306_01/server.102/b14223/usingpe.htm#DWHSG024] in documentation for your version - almost all of these topics are covered there.
1. According to my server specification how much DOP i can specify.It depends not only on number of CPU. More important factors are settings of PARALLEL_MAX_SERVERS and PARALLEL_ADAPTIVE_MULTI_USER.
2. Which option for Setting Parallel is good - Using the 'alter table A parallel 4' or passing the parallel hints in the sql statementsIt depends on your application. When setting PARALLEL on a table, all SQL dealing with that table would be considered for parallel execution. So if it is normal for your app to use parallel access to that table, it's OK. If you want to use PX on a limited set of SQL, then hints or session settings are more appropriate.
3. We have a batch processing jobs which are loading data into the tables from flat files (24*7) using sql loader. is it possible to parallel this operation and any negative effect if enabled parallel.Yes, refer to documentation.
4. Query or DML - which one will be perform best with parallel option.Both may take advantages of using PX (with some restrictions to Parallel DML) and both may run slower than non-PX versions.
5. What are the negative issue if parallel option is enabled.1) Object checkpoint happens before starting parallel FTS (true for >=10gR2, before that version tablespace checkpoint was used)
2) More CPU and memory resources are used with PX - it may be both benefit and an issue, especially with concurrent PX.
6. what are the things to be taken care while enabling the parallel option.Read the documentation - it contains almost all you need to know. Since you are using RAC, you sould not forget about method of PX slaves load balancing between nodes. If you are on 10g, refer to INSTANSE_GROUPS/PARALLEL_INSTANCE_GROUPS parameters, if you are using 11g then properly configure services.

Installing Snow Leopard but also Boot Camp or Parallels

I have a 2006 MacBook (Intel, core duo) and have a 320 gb HD, 2 gb RAM, running 10.5.8.
I'd like to install Snow Leopard but also would like to partition my HD and install Boot Camp (or Parallels 4.x - I have that version, fully paid etc. but not version 5 of Parallels. Or should I move to Parallels 5 if I move to Snow Leopard?)
I have a full bootable backup (2) on FW400 LaCie External HD's. I have the SL Original DVD.
What is the best way to do this? At present I have 60 gb free space (about 20% of the 297 gb formatted total space available).
Thanks for any comments! Oh, yes - I'm anticipating a new MacBook Pro 13" any time now (Thought the new ones would be out by now!) - Well it will come with SL installed; and I will order one with a 500 gb HD (or larger if available then). Can I migrate my current MB data and files to the new MacBook using migration assistant? But what if I want a partition for BootCamp and Windows (XP likely as I have that)--? Should I partition the new MBP HD first (can I partition it without erasing everything?
Best regards,

Frankly, were you to run Parallels 5 you should have more RAM installed, but your model cannot support more than the 2 GBs you have installed now. You would be better off running Windows via Boot Camp on that machine. However, the new computer will have 4 GBs of RAM installed so it is better suited to running Windows via Parallels. And, yes, if you run Snow Leopard you need Parallels 5.x both for compatibility and performance reasons.
Open Boot Camp Assistant and click on the wide button on the left to print out the documentation. Read it carefully before using Boot Camp Assistant. Yes, you partition the drive without erasing it, but you can only have one Windows and one OS X partition on the same drive. Otherwise it makes no difference when you use Boot Camp.
Your XP must be a retail installer with SP2 and only the 32-bit version. You cannot use an OEM installer that came with another computer.

Trouble connecting LaserJet6p to Windows 7 64 bit computer using usb to parallel printer cable

The printer isn't responding at all--not even a test page. I've verified that the correct driver is installed and the computer does recognize the printer (even as the "default").
Any suggestions? The computer is working with my other printer through blue-tooth,,,,
Thanks!
Paul

The USB-parallel cable needs a driver that supports Windows 7 x64 in addition to the driver the printer needs. Additionally make sure the port settings are correct, usually the port will be something like USB001: or USB002: for the USB-parallel port. Some cables may provide a virtual LPT port such as LPT3:. Check the documentation for your unit for details.
The posts here list models of USB-parallel ports folks here have had success with in Windows 7.
