Jtds driver and NT

Hi,
I have been doing some testing of the jtds driver on XP and NT and it seems that the driver runs great on XP but is very slow on an NT 4.0 machine.
Does anybody know of any know problems with this driver and OS?
Is there a better driver I could try out for windows NT 4.0?
Regards.
Alan

I'd guess some would say there is no "better" driver for most definitions of the word...
Perhaps not better but different: http://www.microsoft.com/sql/downloads/2005/jdbc.mspx
Or googling should find several commercial drivers, some come with no-cost trial versions. E.g. http://www.datadirect.com/downloads/registration/connect_jdbc/index.ssp
My first guess is that it isn't a driver issue. I'd start by checking network configuration, seeing how much packet loss "ping" reports, how fast "ftp" can move data from db server to client, ... And checking if the NT machine is low on memory and simply swapping itself to death.
How slow is "very slow"? A simple select takes 10ms, 1sec, 1min, 1h, ...? Compared to what on the faster machine?

Jtds driver creating deadlocks

hi
I have a strange problem i am using jtds driver and have SPs in database i am using SQL server.
i.e.
storeprocedureOne[ select the rows from database]
storeprocedureTne[ delete the rows from database]
both SPs are called using different connection object and different statement object i mean to say both are called by different function but sometimes they are creating deadlocks and i don't understand why.
if anyone have an idea plz let me know
thanks in advance

Here's the problem I'm having. Every time I try to use DriverManager.getConnection, I get the message "No suitable driver". This is some basic code I wrote just to check the driver...
Class.forName("com.internetcds.jdbc.tds.Driver");
String url = "jdbc:freetds:sqlserver://scartin:1433";
Connection conn = DriverManager.getConnection(url,"admin","admin"); I have the .jar file in my classpath, and i'm pretty sure the URL is right, but like i said previously, I can't find any documentation on it at all.
Thanks

'other driver and xa connection properties

A connection pool is configured through the admin server with a third party driver (specify other for database type). The driver is only on the classpath

This submitted without me finishing...
We have configured a connection pool with 'other' type and the jtds driver for sql server 6.5 (net.sourceforge.jtds.jdbcx.JtdsDataSource). The driver is only on the classpath of the managed servers, not the admin server.
In this case, we do not see the XA properties in the advanced options (eg Enable XA Transaction Timeout). I am assuming this is because the admin server does not know if the driver is XA or not.
Is there a way to have weblogic show the XA properties, without placing the driver on the admin server classpath?

NoSuitableDriver exception running against a jtds driver.

I developed my BC using SQL Flavour and now I try to run against SqlServer using Jtds Driver.
I created my connection and tested it : it works fine.
I create a configuration using that connection but when I try to run the tester against the DB I get a NoSuitableDriver error. (No suitable driver found for jdbc:jtds:sqlserver://faac/MSSQLSERVER;domain=faac;)
Shoud register the driver somewhere in my classes ?
What I Missed ?

I'm guessing that the embedded WLS server can't find the JDBC library you are using - you can try adding it to the lib directory of the embedded WLS
Somewhere like: C:\Users\youruser\AppData\Roaming\JDeveloper\system11.1.1.5.37.60.13\DefaultDomain\lib
or directly to the classpath in the startup script:
C:\Users\sshmeltz\AppData\Roaming\JDeveloper\system11.1.1.5.37.60.13\DefaultDomain\bin
or try and mark the library with the JDBC jar to be deployed by default in JDeveloper.

Anybody use jtds driver with creator?

Hello,
I have a creator app that talks to our SQLServer via the jtds driver.
I cannot update any records, I get a "result set is read only" message.
I tried changing the concurrency to CONCUR_UPDATABLE and TYPE_SCROLL_SENSITIVE.
Is there a better Driver to use?
Thanks
Frank

I'm not completely sure I understand what you are saying, especially the part with the updateable and read-only tables (ResultSets are updateable/read-only, not tables). Could you provide an example (Java code or at least the SQL) illustrating your point?
The problem with "this driver" is that in its last public release (1.0.2) it did not implement client side cursors (in fact it did, but only for Sybase). This support has now been extended to SQL Server in cases when the server isn't able to create a server side cursor, so jTDS will cache the whole result on the client and create a client side one. This behavior will be available in the next release (or you can get it from the CVS tree before that).
The problem with transparently creating client side cursors is that this introduces a huge (memory and performance) overhead of which the user is unaware. This may lead to OutOfMemoryErrors simply because the table didn't have a primary key or the SELECT didn't include it.
And now that we're here, let me point out that the DataDirect driver is not the most efficient, by far. There's even a test in their performance test suite (which they use only to point out that their driver is and will be the only one that doesn't fail that particular test), which creates a forward only ResultSet and then calls last() and beforeFirst() on it. This test only works because they cache the entire ResultSet, which may seem like a good thing, but it's totally unnecessary and if you compare the time it takes for that test to run with the time to do a simple next() through the exact same ResultSet it's orders of magnitude larger.
And one final thing: the JDBC spec rightfully states that a JDBC driver implementation does not have to implement features that the underlying DBMS does not support. Creating a scrollable and/or updateable ResultSet from God knows what falls under this category in my oppinion. The SQL Server spec clearly states what conditions must be met by a SELECT query for a server side cursor to be created on it. You can't reasonably expect not to meet those conditions and still get what you want.

I'd love some help trying to figure out why my 2008 MacBook no longer recognizes my external drive and now is not downloading photos from my iphone....?

After many years of having no problems at all on my Macbook, I recently figured I should finally upgrade my OS. I did that about three weeks ago, updating to Snow Leopard (10.6.8). I used Time Machine at least once after the OS upgrade but now Time Machine no longer recognizes the external drive I have used for all these years to back up. The MacBook does not "see" it. (Disk Utility does however.) The computer then also stopped recognizing another La Cie back-up that I have and now... my iPhone cannot download photos? Yikes.
I have, of course, shut down numerous times, used different cables (that worked for some) and the two USB drives. I even used a firewire. Nothing worked. I also tried to "Repair disk" on Disk Utility. It didn't work either, giving me an error (that I didn't save, sorry).
I read many other discussions on the file format of the external drive and of course I'd be happy to reformat the external drives--however, it is obviously a tad nerve-wracking to reformat drives before having an accessible back-up. Suggestions? I do not remember what file format they have but am pretty sure it's not the Mac file system someone mentioned. The drives are a 2009 WD "My Passport Elite" and La Cie 2007 d2 Quadra,
In terms of other hardware available, we do have another MacBook Air but it has started rejecting both drives as well (without the Snow Leopard upgrade). We have an old Dell but it wouldn't have the disk space to help out much.
Any thoughts on the process involved would be welcome. Any ideas on the iPhone rejection would be helpful as well! It is a 30gig iPhone 4 that has 20 or so gigs free (not clear as iTunes says that there are abour 18 Gigs on the phone but 24 free gigs? I may be bad at math but that's 40 gigs...).
I am checking out iCloud but apparently there are only 55 gigs available?
Will be glad to hear any thoughts. Thanks!

Good afternoon Lyssa,
Phew. First of all, thanks in advance...these blogs are always comforting help!
So, to answer your questions: For the age of the hard drive.Well, I added memory a couple of years ago (RAM and hard drive). Being a mom leads me to eat up a fair amount of gigs with photos of my kids and, in fact, I think I entirely replaced the original drive, so it is a couple years younger than 2008 since I did that in March 2010. If there is some way to verify that (whether or not I replaced the entire drive), I'm all ears. I have 311 Gigs free, so it is not a space issue. I verified the startup disk on Disk Utilityand nothing showed up.
Question 1- What formats...
The La Cie is format Windows NT Filesystem 3G ....At the time that I bought it I was still using a PC as well as a Mac and was told by afriend to use this format...
The WD is Mac OS Extended (Journaled). I again tried to repair the WD last night and this is the error message: "Error: DiskUtility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files."
Also, Time Machine tried again to back-up and gave me this error: "Files can't becopied onto the backup disk because it appears to be 'read only'. You may needto repair or reformat the disk using Disk Utility. If the disk can't berepaired, you must use a different disk for backups. Open Time Machinepreferences to select a different backup disk."
Question 2. Other cables...
I used two other cables with the WD and that didn't change anything.
Question 3... Fire Wire from the La Cie
Yes, I used the Firewire cable from the La Cie and it is indeed present, though still not visible in Finder. Since it is not Mac OSExtended I know that I can't use Time Machine with it.
So, in summary...
I can plug in the La Cie and it is functional on the MacBook, visible on Disk Utility but not visible in Finder. The WD drive is not visible and not functional. So we can think it is indeed the WD that is not working.... Also, the iphone photos did, in the end, get downloaded, so it is not something more general.
Causes...
I forgot to mention that there is a "lost+found" file on the WD which apparently points to a UNIX /OS issue?
Some kind of "insurance"?....
I'm curious about how people avoid this kind of issue. You just regularly replace back-up drives and hard drives before problems come up? Time Machine is great and saves many of us from disasters, however, knowing that your Time Machine back-ups are vulnerable makes the whole system insecure. No way to have alarms ring before the drive goes out?
As for ways ahead...
It seems that I ought to be able to copy off of the WD to the MacBook then erase it and reformat it and start over again. However, I haven’t been able to see its contents except on random occasions. If you have any ideas on how to copy the Time Machineback-ups from the WD, again, I'm all ears!

I want to remove all of my photos out of iPhoto there are approximately 35000 some imported from an old hard drive and a SD Card from my Nikon D500 how do I do this

I want to remove all of my photos out of iPhoto there are approximately 35000 some imported from an old hard drive and a SD Card from my Nikon D500 how do I do this?
I have iPhoto version 9.1.5 (615)
Mac OS X version 10.6.8
I want to do this because when I imported from my old hard drive there was an error message stating that 12 photos were not imported as the programm did not recognise the format even though they were jpegs like the other photos in that particular album. The dates of the photo folders are wrong I have multiple copies of photos and every time I start iPhoto I get the following message 12 photos have been found in the iPhoto library that were not imported would you like to import them No or Yes
if you press Yes the same message comes back again and if you press Yes again the program flicks to last import for 2 seconds and then opens events.
if you press No the message The photos have been placed in the folder/user/judith/pictures/iphoto Library recovered photos then if you press OK the original message 12 photos have been found.............
if you press No at this point the message The photos have been placed in the folder/user /judith/pictures/iphoto Library recovered photos_11 the end number goes up by 1 every time you go through this process
Any help would be greatly appreciated

Did you import an iPhoto Library from the old Hard Drive? Do you still have that old Library?
The way to clear out a Library is to Export the photos - Apps like iPhoto2Disk or PhotoShare will help you export to a Folder tree matching your Events.
For the annoying start-up message:
Go to your Pictures Folder and find the iPhoto Library there. Right (or Control-) Click on the icon and select 'Show Package Contents'. A finder window will open with the Library exposed.
Look there for a Folder called 'Import' or 'Importing'.
Drag it to the Desktop. *Make no other changes*.
Start iPhoto. Does that help?
If it does then look inside that folder on your desktop. Does it contain anything you want? If not you can trash the folder.

I'm using Time Machine and a LaCie external drive to backup. I also have a 8 GB LaCie flash drive I want to use for small jobs. If I plug the LaCie flash drive in, is my Mac going to think it is the LaCie external drive and start trying to backup?

Help - moved itunes folders to external drive and now my itunes is totally

A few months ago, in order to free up space on my c drive, i had to purchase an external drive - everything i installed via itunes since that date has been on the hard drive and everything was fine.
Last night i needed more room on my C drive so i stupidly moved the remaining itunes folders from my C drive to my F drive - unfortunately, when i opened itunes it was blank.
i've tried a few things - including adding the folder from the F drive - and that retrieved about 80% of my music/videos and the last playlists i had - however, they were all missing songs - even if all the songs that should be included remained on my itunes
i began the tedious process of manually adding files back in but soon realized this doesn't help itunes consider this the same ipod as what's still on my actual ipod.
*What I'd like to do (if possible) is to wipe itunes clean and somehow restore everything on my ipod into itunes so that i retrieve not only the songs and videos but also the playlists that i've spent way too much time building. At this point i fear that the various components to my ipod are in too many files on my external drive to be easily restored another way (though if i'm wrong please let me know)*
sadly (as this story might suggest) I am borderline computer illiterate - I've read a few posts suggesting some sort of software online (something the apple help line also made an "off the record" remark about) - but I can't for the life of me figure out which i would use or how to do this without risking the contents of my existing ipod (which has the playlists and songs/video I want to reestablish).
*Can anyone possibly suggest how to best handle this and walk me through it in painstakingly basic and specific detail? I would be forever grateful.*
Thanks

iTunes uses the iTunes Library files - in particular the iTunes Library.itl file - to keep track of where your song files are located as well as playlist and related information.
Most likely in moving your folders around iTunes has been confused to such an extent that it created a new Library file. With a bit of luck you might still be able to find the old file which would restore your old Library.
So the first thing you want to do is look around your computer and make a note of any iTunes Library.itl files you can find. Generally speaking you'll find them in the iTunes folders on your system and depending on how you've been moving the folders - i.e. whether you "cut" them or "copied" them - you may still find at least one one on your F: drive and some on your C: drive.
Having noted where they are you know want to check each of them out as described in this article in the Apple Knowledge Base. In following those instructions you want to select the Choose Library option and use the pop-up window that appears to zero in on the various .itl files you've located.
Remember that each Library file will show a different Library in iTunes - perhaps slightly different, perhaps completely different - and if the first one isn't what you're looking for you'll have to close iTunes and repeat the procedure by selecting one of the other .itl's.
Post back for any clarification.

500GB drives and backing up

I will be buying a Mac Pro in the very near future, as I'm after a machine that has plenty of upgrade potential (and I get a pretty good Apple Store discount with my employer).
I have a lot of audio files, large aiff files for audio production and around 150GB of mp3 files. After doing some reading here, it seems my best option is to have the stock 160GB drive from Apple, remove it, and install a 3rd party 500GB from day one. Now, in terms of backing up my files, I'm a bit unsure of how to go about it. Should I get a second 500GB drive purely to back up the first drive? Would this be achieved through RAID? And how exactly would the RAID configuration work in this case? Being honest, I've never had any experience with RAID, but if it's suitable for my needs (or not), I would appreciate anyone who can steer me in the right direction.
Thank you.

Hi bos bos!
And Welcome to Apple Discussions!
No need to apologise here some are just a bit high on life
If I was you this is what I'll do (which I'm thinking of probably doing):
1. Get the stock 250GB you don't get much credit downgrading - and use it as your boot drive. If you however decide that you want another powerful or silent drive then you can upgrade in the future. Check this thread: Western Digital Raptor and Tiger concerning Boot drives and some serious great advice!
2. Get an external 250GB FW HD (FW 800 would be great but expensive) and use that to clone/back up you Boot Drive via SuperDuper weekly or when you like. You can also backup to internal 250GB Hard drive. Usually clone your drive before upgrading or installing firmware or security installs, etc.
3. If your going to run windows, buy another internal drive for it. So its seperate
4. Buy a larger drive eg. 500GB and use it for data, move your home folder to it eg. documents, itunes, movies, etc. Thus if something goes wrong with Tiger you can just reclone it back without affecting your personal data. Get another FW 800 External drive and backup that drive to it. Maybe some synching program as well that only updates the changes made daily or every 6 hours or so. And backup to DVD always and store off-site.
5. Forget RAID, if you do not know what it is you do not need it. Hey I'm still trying to understand it but I do not need it! But from what I understand it is used mostly for backup purposes by combing 2 or more drives together where people need large amounts of hard drive space. Some people will (and you will notice them here in the Mac Pro thread) use RAID as Boot Drive. But notice they are high end users and know the risks. Also note that you cannot update or install apple firmware in Tiger if your running RAID.
These days External HD are really cheap (but do get quality ones) especially FW400 and USB2. I was considering buying three drives something like 250GB and use them as a 3 day concurrent backup - eg. Monday, Tuesday, Wednesday and then rotate use Monday for Thursday and so on. Then I've got 3 days of backup so if something goes wrong I can always go back to it.
If you have a basement/garage anywhere its reasonable to store a PC and have used PCs before what you can do is buy yourself a cheap ATX Cabnet (sells around £20) get a cheap motherboard, RAM, Gigabit Network Card and stock it with 4x250GB internal HDs and share over the network. Obviously do not connect it to the internet and keep it on its own subnet. Its surprisingly easy to configure this and it'll cost you the same amount of a 3-400GB external drive maybe even less.
Instant Storage. Use PC's what they were built for - basement/garage trash that no one needs to see

Cannot format hard drive and do a clean install

I'm in a pretty big mess right now. I was using boot camp with lion and Windows 7 no problem and I wanted to edit the sizes of the partions. It didnt go so well and I ended up losing both operating systems. Now the big problem is when I boot up from the recovery partion I cannot do any sort of formating from the disk utility, it always give me some sort of error. When I try to install lion via web there is no partion that I can Install it to. I can install Windows no problem from a USB drive whcih I have done already. When managing the disk in windows I see 2 of the windows partions, the mac recovery partion, and an 80 GB partition that I can format but I cannot do anything else with. I dont have any images or recovery devices other than the recovery partition. I need some advice on how to get the drive back to mac format so I can re install lion.

From the disk utility every time I would try to format the partitions or resize anything it would say cannot unmount disk and there was another error I cant remember. I think I'm on the right track though. What I've managed to do so far is with the disk utility on the recovery partition, I formated a usb drive and then installed Lion on that drive. The drive is painfully slow but it seems to be working. Where I am at now is I have booted from the the flash drive and managed to Format the Hard drive back to mac format and I am now creating an image of the USB stick that I can hopfully copy to the hard drive. Creating the image is taking a while due to the crappy transfer rate of the USB stick.
If you have any suggestions of where to go next or what to do I would appreciate it.

I have a 500 GB hard drive and a 1TB Time Capsule running on a MacBook Pro. It was all working well until the MacBook went in for a repair a week or so ago. Since then, TC will not perform a backup; instead, it says the backup is too large for the disk

Since having my MacBook Pro repaired (for a video problem) Time Capsule returns the following message: "This backup is too large for the backup disk. The backup requires 428.08 GB but only 192.14 GB are available."
I notice that there is also a new sparse bundle.
Since TC has my ONLY backup (going back about 4 years) I am reluctant to wipe it and start over fresh as I am afraid of losing files.
Is there a way of dealing with this?
I am using Snow Leopard 10.6.8

The repair shop likely replaced a major circuit board on your MacBook Pro, so Time Machine thinks that you have a "new" computer and it wants to make a new complete backup of your Mac.
You are going to have to make a decision to either add another new Time Capsule....or USB drive to your existing Time Capsule....and in effect start over with a new backup of your Mac and then move forward again.
For "most" users, I think this is probably the best plan because you preserve all your old backups in case you need them at some point, and you start over again with a new Time Capsule so you have plenty of room for years of new backups.
Or, as you have mentioned, you have the option of erasing the Time Capsule drive and starting all over again. The upside is that you start over and have plenty of room for new backups. The downside is that you lose years of backups.
Another option....trying to manually delete old backups individually....is tricky business....and very time consuming. To get an idea of what is involved here, study this FAQ by Pondini, our resident Time Capsule and Time Machine expert on the Community Support area. In particular, study the pink box.

Once you look through this, I think you may agree that this type of surgery is not for the faint of heart. I would suggest that you consider this only if one of the other options just cannot work for you.

Backing up photos on iMac using external hard drive and time machine

How do i back up photos from my imac using an external hard drive and time machine
Thanks in advance

Apple explains how to use Time Machine in http://support.apple.com/kb/ht1427.
Setting up and using TM is very simple to do, connect any external HD (format as Mac OS Extended (Journaled) using Disk Utility ) and your computer shoudl ask if you want to use that EHD for a Time Machine backup. If you have any questions visit your local Apple Store or reseller and they can answer how to setup and use TM and also should be able to offer suggestions on EHDs. My personal preference is OWC (www.macsales.com) Mercury Elite Pro due to the build quality and OWC's level of support.

Upgrade MacBook - Hard Drive and RAM

I want to upgrade my daughter's early 2008 white MacBook - both internal drive and RAM. I know how to install both and have done so before. I have purchased the internal drive, the RAM and a large external drive for Time Machine backups now and for the future. I also want to install Lion. I'm not sure of the sequence... Here is what I propose:
1) format the new external hard drive and then back up the current internal drive using Time Machine.
2) install the new RAM.
3) install the new internal drive.
4) boot up using Snow Leopard DVD. Install OS 10.6
5) upgrade to 10.6.8
6) install Lion.
7) import all of her applications, files, etc. from the Time Machine backup.
8) done?
Is this correct - will all work?
9) back up the new internal drive using Time Machine.
Will step #9 work when I select "Back Up Now" from the Time Machine?
10) If yes, is her itunes account, etc. ready to use? Can she sync iphone as before?
Thanks.

I can make this easier for you:
1) Download and install SuperDuper.
2) Using SuperDuper, make a clone of the current internal drive to the large external.
3) Test the clone by booting to the external drive
4) If good, install the new internal drive.
5) Boot from external, and use SuperDuper in reverse (clone back to new internal).
6) When done, boot the mac normally. Upgrade to Lion, and all should be good.
