Question about 6 Way Firewire Port and Ex. HD's

I recently bought the Belkin 6-Port Firewire adapter. Right now I have two external HD's ( 200 GB and 300 GB ),and my iSight connected. I was wondering if it was safe to have my two HD's always connected? I've been having issues with my screen turning dim and not coming back to normal until I restart. I reset the PRAM and still after using my iMac for awhile the screen turns dim, like as if were about to go to sleep, but when I try to brighten it, it stays the same brightness?

Assuming the harddrives have their own power supply the issue us unlikely to be related. Its unlikely to be related either way.
Are you sure you are not losing connection to the keyboard so when you try to brighten it takes a while for the keyboard to reactivate, plenty of people have had issues with the keyboard.
Also you can switch off the totally pointless slight dimming thing in the energy saver part of system prefs

Why would the Firewire Port and/or External DVD-RW suddenly not work?

Hi, it's me again. I swear, I must be destined to just use Windows machines...
Anyways, I have a used/refurbished iBook G3 500MHz 320MB RAM Dual USB (1 Firewire)laptop running OS 10.2.8 that I bought a few months ago. I went and purchased an external Firewire/USB 2.0 DVD-RW drive as I only had a CD-ROM drive on my machine and I wanted the option to burn CD's or watch/read data from DVD's (I know that with my slow processor writing DVD's -other than data- would be a stretch and have other machines to do that with anyways so it wasn't a concern really). I received it and installed it, also installed the free version of Toast that came with it, and the drive worked fine. I have not needed to use the drive since then and have not used the laptop much at all since then really, but I do need to say that I did end up adding a new user account, though I can't remember if I changed the original Admin account and then still have the one I created myself when I first started the laptop after I bought it (had a fresh install of Jaguar on it, but I have no disk to re-install with if needed) or if I created a separate (new) account and ended up deleting the Original Admin accout (I know in Windows, you cannot delete the original Admin account but I do not know if that is the same for OSX or not). I did this as I wanted a master Admin account that I just wouldn't really use and then wanted the other as my main account (and use it to connect to my home windows network) and for some reason it would not let me put a check in the box to allow that account to do so (from either Apple or my user accounts) and so I know that my main user account now is set up to allow it (was it the old Apple user account or a new one, I can't remember- sorry).
Ok, so that is the back story to my problem, which happens to be this:
I just bought a new chip of RAM (512MB to make it a machine with 576MB RAM total) and as I had been looking at getting OSX Tiger (but didn't want to do it without the extra ram and had been considering Panther instead as well), I thought it was necessary if I wanted to not bog down my machine. I bought the Install Disks on DVD for Panther, as well as an upgrade disk (DVD again) for Tiger, therefore letting me use the External Firewire DVD-RW to install Panther, and if I liked I could go ahead and upgrade to Tiger (and if I didn't like it too much, or it slowed things down too much etc, then I could always go back to panther and have both available for future options). The extra RAM coming in handy here definitely.
So I was going to install the RAM today, and decided to go ahead and test out the External DVD to make sure it could boot from it (before making any changes to my system) and then go and install the RAM, and after that, install Panther to start... But I plugged all the cords and cables in, used my laptop with AC power even, and I could not get the External to show up at all... (kinda like the very current post right below mine but for the G4- it worked before, but now the firewire External just does not show up).
I only have USB 1.1 on this laptop obviously, and I don't even know if you could do a boot from an external with USB 2.0 if my laptop had it (the DVD player does). I was recommended to boot with an external firewire DVD or firewire to another machine with DVD capabilities to do the install. So my problem right now is getting slightly bigger, as of course, I can't seem to momentarily find the stuff that came with the External (spare USB cable to check and see if the laptop will recognize it at least with that and to show it is the firewire that is not working properly, or the disk that I used to install it -might have been only used to install Toast free version if it didn't need any drivers, but I don't know where that or the instructions for installation sheet currently is -- I am looking for it, but I have switched bedrooms just last week and I also seem to be missing a few other Windows laptop disks as well so there is a good chance that they are all together, I just need to figure out where, heh.)
I am waiting currently before installing the memory, though if I don't get the External working tonight, I may go ahead and do it first as at least I will have more memory on my laptop then, until I can get other stuff functioning and be able to do the Panther install.
But my main question is, is there something that would cause an installed external to suddenly not show up in OSX? Since I hadn't used it since that one day, and it was unplugged from the laptop itself, would that end up doing it, or more likely, the changing of the user accounts (though I have been trying to test it with different types of media and through both of my user account (which are both "admin" ones), though I do still have one of those being an account that was on there when the External DVD was first installed, so it really shouldn't have done this at all (one would think). So how big of a chance is it that the firewire has somehow gone dead and this is the main culprit to my wasting the past 4 hours on this???
I am currently scavenging around for an extra USB cable to try and test the External that way and will post the results when I can... I love the look and idea of macs, now I have a mac and want to upgrade it even, but why is it that whenever I attempt to use it after having not used it for a bit (and try to make the iBook feel better by using it more as I am sure it feels sad and alone sitting on the shelf while my Windows Laptop gets more attention), or try to fix it when it can be made better (and therefore used more often), the mac (all macs really), just seem to get all pissy and cause problems and make me spend hours upon hours trying to get things to work again??? You have to admit it, I am "mac cursed"... sigh I can program in 4 or 5 computer languages and am very advanced at many tech things (the ones I am not as good at I am still usually Average or Medium skilled) so it makes me wonder why I have so many tech problems with Macs when they are supposed to be the "easy" OS to use...

Actually, I think I have it all working now. After going back to the Plextor Website, I found out that the switch between the USB and 1394 ports only gets activated (switched over to the other) with you turn the device off first, move the switch and then turn it back on. I was sure that I had done this with the ibook, but maybe not as when I went back and did it with first the USB and then the Firewire cables, it did work. I definitely knew that I had not done this with the Windows laptop, the reason it would not have the USB work for me on it.
but back to the iBook, I was confused as it was only showing up as a DVD-ROM (which I guess is what they do until you actually open up the burning software to then be able to burn to it), and it also had the wrong Model #, which after more research, showed that it was the Internal DVD drive model version (PX-708A) compared to the actual model version (PX-708UF) which is the USB/Firewire (External) model. The firmware was really out of date as well (from June 2004 I think, v1.06) and they had v1.12 from Spet/Oct 2006 available so I went to get that (which was a hassle). They had nice easy Windows self extractor/installer packs, and then the BIN files for use for all systems (Sun OS/ Mac OSX/ Mac OS/ Linux etc as well as usable for Windows), and those needed a special Firmware Updater Application which was OS specific. Only I had the hardest time trying to get the OSX one as it would send me to a FTP site and not give me any clues as to which file(s) I needed to get and the Mac OS version was just for older 9.2 or below versions and didn't want to install under the OS Classic mode.
I ended up using my windows computer which made it easier to view with the FTP stuff as I have FireFTP in Firefox, and downloaded the files I thought I needed (to test out), and then realized my silliness, and just downloaded (as well) the Windows Auto Extractor/Installer as the Firmware is the same for all OS's, just the way to install/update it was different... So I hooked the DVD drive to my PC and updated the firmware, checked it out on here before moving it back to the ibook, where I checked that it still worked and had the new update version showing, which it did, and now I have my fully working and newly updated drive ready for the OSX installations... I had attempted to update my Jaguar system as well while online, but it had no new updates available (I guess those were all mostly Tiger updates that were just recently released).
I am now off to install my additional RAM, and after checking that it all shows up correctly, I will go ahead and do the Panther Install (and test it out and see if I like it or not).
For anyone that currently uses Panther on any mac, are there still any major problems I should know about before hand, or know about things that they have mostly fixed (like the issues with Firewire ports and External Drives that they had around the time Panther was first released for example)???
Thanks to all that helped... I now know to attempt an "eject" of any external HD (which I do have one that I will setup to use after I get Panther on the ibook) or CD/DVD drive instead of just unplugging the USB/Firewire cable.

IMac i7 Quad-Core firewire port and video camera

Has anybody tried to detect a video camera connected to the firewire 800 port?
I have already tried with two PRO tape-based DV video cameras: SONY PD170 and PANASONIC AG-HVX200E with no results. The same models do not have any problem with iMac 27" Core Duo 2.
Apple care protection plan has been useful only to know that if my iMac firewire port can handle an external Hard Disk, as it does, the compatibility with the camera is not a problem of Apple, but simply mine.
Any suggestion? Any help to find official pages by Apple with technical specification about firewire port and protocol of the new iMac 27" i7?
Thanks, Carlo

Today my Mac has finally been fixed. I had to send it to Milano, to SATA srl, where they have replaced the logic board. Now I can import video from my video camera using the FireWire port. Thank SATA!!!

I have just upgraded from a Macbook to a Macbook Air. I have been using a iomega external hard drive for Time Machine, which use a Firewire. However, Macbook Air's do not have a Firewire port and i cannot find an adaptor anywhere. Can anyone help?? Thanks

There has never been a reliable firewire ---> USB adapter suitable for external high speed storage. This was a major issue when the MacBooks lost the firewire port a number of years ago (Apple subsequently brought it back).
The only high speed port on the Air is the ThunderBolt port. There are external ThunderBolt drive options out there, but they're somewhat more expensive than traditional USB/FireWire options.

Here's a very basic question about 2 TB external drives and Time Machine.

Here's a very basic question about 2 TB external drives and Time Machine.
Ihave a Mac Pro with a .75 TB and 1 TB drive. It also has a 1 TB 2ndinternal drive. My current external drive is too small so I'll begetting a 1.5 TB or 2 TB drive.
Obviouslythe new larger 2 TB drive will backup everything on the Mac Prointernal drive with Time Machine. But there will be 1 TB of space leftover going to waste.
ShouldI partition the external drive so that the TM portion will be 1 TB andthe use the remaining extra partition for additional file backups withCarbon Copy?
Thanks for any insights.
I tried searching around on the new Apple discussion forum, but I find it much harder to use than the old forum I used to use.

The problem with terabyte drives is that that a 3 TB is about as big as you can get without going into RAID territory. Ideally, a Time Machine drive should be 3 times as large as all the drives you are backing up. So, if you have 2.75 TB of internal storage, you should have 8 TB of Time Machine space.
Of course, that is "should". If your TB drives are mostly empty, then you can get away with something 3 times the size of your used disk space. Just remember that you are pushing it. Linc is right about Time Machine needing space to work.
It is unlikely that you have regular churn on 2.75 TB of disk. I suggest identifying which drives and folders have the most activity and excluding those drives and directories that don't change much. It would be better to archive the data that doesn't change often and keep it out of Time Machine. Then you may be able to get away with a 2 TB Time Machine drive.

John,
I'm not sure why you posted in the iMac forum so I'm going to attempt to get you to the correct spot. I would recommend reposting in the Time Machine Forum, this is part of the OS X forums (Leopard or Snow Leopard) because you are using Snow Leopard (your profile indicates you are) please click Apple Support Communities and type Snow Leopard. Then you can narrow the search down by clicking Refine this List.

3560 and 3750 - Question about 10/100/1000 ports

I am researching several Cisco products to recommend to a customer. I was wondering if the 10/100/1000 ports at a 3560 switch, will provide gigabit bandwith on each port or if the bandwidth is shared among several ports. The latter is how a 48 port 10/100/1000 line card would behave on a Cisco 4500 when, depending on the card, the gigabit bandwidth will be shared among 4 or 6 ports at a time.
What about 10/100/1000 ports on a 3750?
Thanks

The new Catalyst switches/modules such as the Catalyst 6500/6000, 4500/4000, 3550, and 2950 support 10/100/1000 Mbps negotiated Ethernet interfaces or ports. These ports work on 10Mbps, 100Mbps, or 1000 Mbps speed based on their connection to the other end. These 10/100/1000Mbps ports can be configured for speed and duplex negotiation in the same way as 10/100 Mbps ports on CatOS or Cisco IOS Software-based switches. Therefore, the configurations given in this document for 10/100Mbps port negotiation applies to 10/100/1000Mbps ports as well.

Some basic questions about rmi registry context "bind" and "lookup"

We have more processing to do than can be accomplished with a single computer. To solve the problem I've implemented a distributed computing solution using RMI. (The first time I saw RMI was about 2 weeks ago, so please bear with me!)
The implementation is a proof of concept not a fully fleshed out system. I have one "Workunit Distributor" computer and any number of "Data Processor" computers all on the same lan segment. "Workunit Distributor" and "Data Processor" computers are both RMI client and server to each other. The "Data Processor" computers are given the ip address and name of the "Data Distributor" on the commandline when they start. They communicate their willingness to receive and process a workunit to the ""Workunit Distributor" via a RMI call. Work units are sent to available "DataProcessors" and results are eventually returned to the "WorkunitDistributor" (minutes or hours later). The model program works quite well, and appears to be capable of doing the processing we need to get done.
But now that it seems viable, I've been asked to make it a little more scalable, flexible and self configuring. In particular, instead of one "Workunit Distributor", any number of "Workunit Distributors" should be allowed to show up or disappear from the lan at any time and the system should continue to function. I've worked out a good scheme for how this can be done, but I have a couple of questions about the RMI registry (registries?). I'm trying to keep from implementing some functionality that may already be available as a library or subsystem.
With my current model design, each computer binds to its own registry with a unique name. For instance:
CRDataProcessorImpl crdpi = new CRDataProcessorImpl(svr);
Context crDataProcessingContext = new InitialContext();
crDataProcessingContext.bind("rmi:"+hostName, crdpi);
Currently the "Data Processors" get the info they need for a Context lookup() of the one and only "Workunit Distributor" from the commandline. And the info the "Workunit Distributor" needs to do a Context lookup() of a "DataProcessor" is passed to it from each "DataProcessor" via a RMI call.
But in the newer (yet to be implemented) scheme where any and all "Workunit Distributors" show up and disappear whenever they feel like, the naming bootstrapping scheme described above won't work.
I can imagine a few ways of solving this problem. For instance, having "Workunit Distributors" multicast their contact information on the lan and have a worker thread on each "Data Processor" keep track of the naming information that was multicast. Another alternative (more organized, but more complex) might be to have a dedicated host with a "well known" address and port that "Workunit Distributors" and "Data Processors" could all go to, to register or look up at an application level. Sort of a "domain name service" for RMI. But both these schemes look like a lot of work to implement , debug and maintain.
The BEST thing would be if there was one plain vanilla RMI registry that was usable by all RMI enabled computers instead of having each computer have its own local name registry. In volume 2 of the Core Java2 book it says that every registry must be local. I'm only hoping there's been progress since the book was published and now a central rmi registry is available.
If you have any ideas about this I'd like to hear what you know.
Thanks in advance for any advice.
Lenny Wintfeld
ps - I don't believe web services, as full featured as it is, is a useful alternative. I'm moving 100's (in the future possibly 1000's) of megabytes back an forth for processing.

The local bind/rebind/unbind restriction is still there and it will always be there.
I would look at
(a) RMI/IIOP, where you use COSNaming as a registry, which doesn't have that registriction, and which also has location-independent object identifiers
(b) Jini.

A few question about iPhone OS in CS5 and CS5 in general.

Hi,
I'm an IT trainer and I am trying to introduce my students to programming for iPhone/iPod Touch. (They are Secondary 2 students. 14 years old) The school is using a windows computer and CS5 right now is the best for the class (Not a steep learning curve and a user-friendly program). I know about the problems over the iPhone OS in CS5 with Apple but I was told it is still available for use. Furthermore, we have no intention of bringing the apps created to the Apple Store. I've tried the trial version and before I make any purchase, I would actually like to ask a few questions.
Is the iPhone OS in the trial version itself complete? Is there anything left out from the trial version because when I tried it, it seems fine however I did not try publishing to an iPhone due to the certificates. Is there a reason for the certificate? Is there any way around it because if there isn't do I need to get a certificate for every single student? (I'm looking at a class of 40 students.) Is the certificate available for windows platform?
Lets say, I got myself a certificate, create a simple program and then publish it, can I immediately bring it over to iTunes and then sync? Will it work that way? I don't want it to be too tedious for the students to see the end result. I've done quite a few research and have come across people having problems bringing it into their devices. Those people mention about bringing it to Cydia and needing to jailbreak the device. The devices made available for the students are not jailbroken. Will iPhone OS with proper certification still need Cydia for use with their device? Will only jailbroken device allow a CS5 app? I hope you get what I'm trying to say. We as trainers do not support teaching students to jailbreak, so that's definitely a no-no.
Another thing about CS5. Previously I have called customer support about the CS4 the school is using now and the problem with nested animation when publishing the animation as a video file, is this problem still in CS5? Does CS5 allow nested animation to be published as a video file? If it isn't, is there any way around it?
Thank you for your time and patience in answering my questions.

Firewire as audio out - can i send my iTunes out through my firewire port and into a DAC?

I have a 5 year old (retired) MacBook with firewire 400 and 2 USB 2 ports. I want to use it as my music source for a fine stereo system. I want to know if I can use my firewire port to ship my digital music signal out to a DAC before sending it to my pre-amp in analogue format. OR, can I use the optical digital audio out in the heaphone jack to do it? What is the bandwidth of the optical out?

You do not need .Mac in order to send photos by e-mail. It sounds like you use ATT as you internet provider. Have you configured Apple Mail to be able to send e-mail yet? Can you send an e-mail text message OK?
If you haven't yet gotten Mail configured to work with your ATT account a quick call to ATT should give you all the information you need. Setting up Mail is easy.
Post back with further questions.
Regards,

Older ACD USB/Firewire ports and a Thunderbolt MBA.

I have an older Apple Cinema Display (20) and a Thunderbolt MBA. Can I use the Firewire ports on the ACD if I use a Thunderbolt to DVI adapter?
Specifically, I have an older iSight external camera (Firewire based) that I would like to use with the ACD whilst the MBA is in clamshell mode. With the Firewire ports on the ACD, I'm intrigued by how I might access them with the MBA.
Is this possible?
TIA,

Same here. Since a few weeks, my MacPro ejects USB HDD's as soon as I write or read data on it.
(no I haven't installed something new at this time and all HUB's and HDD's have their own power supply, and yes they have been exchanged, so its not a broken cable or so !!!!!!!!)
After a reset of the NVRAM and PRAM its better for an hour or so, then starts to eject again. I've seen a lot of communities with exact the same question, but never a solution for it. There is also nothing in the support tab of apple.
Hope someone here can help me out or due to the fact that this is a AplleSupportCommunity, a Apple-Employee may starts to do his job and help this huge amount (I guess there are hundrets or tousand) of mac-user with exact the same problem....
btw: don't agree with MACATTACK2010 that this is a hardware problem, cause there are a lot of people in the
net that ask the same question with brandnew Hardware. I think it's an OS or an Update Bug, or may both.

Some questions about javacard 2.1.1 and smartcardio

Hello i have some question about java card 2.1.1 and the smartcardio package.
1.) I want to sign a message with the Signature.ALG_RSA_SHA_PKCS1 algorithm. I use the following code in the applet to sign the message:
final static byte P1_CREATION_MODE = (byte) 0x01;
final static byte INS_SIGN_MODE = (byte) 0x60;
final static byte SmartCard_CLA = (byte) 0xB0;

        byte[] buffer = apdu.getBuffer();
        byte byteRead = (byte) (apdu.setIncomingAndReceive());
        signature.init(privateKey, Signature.MODE_SIGN);
        short length = signature.sign(buffer, ISO7816.OFFSET_CDATA, byteRead, buffer, (short) 0);
        apdu.setOutgoingLength((short) length);
        apdu.sendBytesLong(buffer, (short) ISO7816.OFFSET_CDATA, (short) length);
        apdu.setOutgoing();
    }On the host side I use the following code to connect to the card and to send the sign apdu:

        } catch (APDUException ex) {
            ISOException.throwIt((short) (SW_APDU_EXCEPTION + ex.getReason()));
    }The error code is 6700
4.) My last problem ist, that i am not able to use a value bigger than 0x7F as the ne field in the apducommand, because i get the following error
CommandAPDU((byte) 0xb0, (byte) 0x60, (byte) 0x01, (byte) 0x00, data, (byte) 0xff);
java.lang.IllegalArgumentException: ne must not be negative
        at javax.smartcardio.CommandAPDU.<init>(CommandAPDU.java:371)
        at javax.smartcardio.CommandAPDU.<init>(CommandAPDU.java:252)I thought that it this should be possible in order to use all the bytes of the response apdu.
If you need more code to help please let me know.
Cheers

2) What is PKCS? what is the difference between
PKCS#11 and PKCS#15??PKCS is the abbreviation of "Public-Key Cryptography Standards"
PKCS #11: Cryptographic Token Interface Standard
See http://www.rsasecurity.com/rsalabs/node.asp?id=2133
PKCS #15: Cryptographic Token Information Format Standard
http://www.rsasecurity.com/rsalabs/node.asp?id=2141
If you want to use yor smartcard as secure token it doesn't have to be a JavaCard.
BTW: I don't remember a way to access PKCS#15 tokens on a JavaCard from within an oncard JavaCard program. If you want to use keys in your oncard program, you have to transfer it onto the card or generate it oncard and export the public key by your own oncard/offcard code.

Firewire ports and power draw while sleeping

After plugging in a power meter, I noticed my iMac was puling approximately 13W while sleeping. A bit of unplugging narrowed it down to the firewire ports. Each one was pulling about 6W, even while sleeping.
Will the firewire ports still draw power if the device is turned off? I'm specifically interested in an external drive that has a hard power-off feature (as opposed to simply sleeping). I'd like to keep it plugged in (I had been unplugging the cable except when needed).
I now I can check this myself, but I'm using the power meter for another project right now and don't want to unplug it and start over, but would like an answer "now."
Thanks in advance.

An open cable connected to any port draws no power. Think of it as kind of a cable to nowhere. Now...connect it to some external object such as a printer or external hard drive and the current draw of the device determines how much power is drawn. Most devices in standby draw about 5-15W depending on their complexity.

Some questions about the integration between BIEE and EBS

Hi, dear,
I'm a new bie of BIEE. In these days, have a look about BIEE architecture and the BIEE components. In the next project, there are some work about BIEE development based on EBS application. I have some questions about the integration :
1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?
could anyone give some guide for me? I'm very appreciated if you can also give any other information.
Thanks in advance.

1) generally, is the BIEE database and application server decentralized with EBS database and application? Both BIEE 10g and 11g version can be integrated with EBS R12?You, shud consider OBI Application here which uses OBIEE as a reporting tool with different pre-built modules. Both 10g & 11g comes with different versions of BI apps which supports sources like Siebel CRM, EBS, Peoplesoft, JD Edwards etc..
2) In BIEE administrator tool, the first step is to create physical tables. if the source appliation is EBS, is it still needed to create the physical tables?Its independent of any soure. This is OBIEE modeling to create RPD with all the layers. If you build it from scratch then you will require to create all the layers else if BI Apps is used then you will get pre-built RPD along with other pre-built components.
3) if the physical tables creation is needed, how to complete the data transfer from the EBS source tables to BIEE physical tables? which ETL tool is prefer for most developers? warehouse builder or Oracle Data Integration?BI apps comes with pre-built ETL mapping to use with the tools majorly with Informatica. Only BI Apps 7.9.5.2 comes with ODI but oracle has plans to have only ODI for any further releases.
4) During data transfer phase, if there are many many large volume data needs to transfer, how to keep the completeness? for example, it needs to transfer 1 million rows from source database to BIEE physical tables, when 50%is completed, the users try to open the BIEE report, can they see the new 50% data on the reports? is there some transaction control in ETL phase?User will still see old data because its good to turn on Cache and purge it after every load.

Hope this helps
