Suggestions needed for NAS

I'm looking at upgrading my home kit. I want to ditch the MDD and get a laptop instead (it's a space issue). As this is going to remove 1TB of available storage, I'm after a NAS to replace it. Can anyone recommend one based on the following criteria, in order of importance:
1. It must be quiet. This is non-negotiable. I have a small flat and there's nowhere discreet to put a noisy box.
2. There must be some data safety. Ideally, I'd like to use this as the backup device for the laptop as well as bulk data storage and I'd like to RAID it if possible. So a single disk is out.
3. Future-proof. Ideally, it'll be upgradeable. I may need more space in the future.
I've been looking at QNAP, Netgear's ReadyNAS and D-Link's DNS323, but there's very little info on noise specs. And I don't take marketing speak at face value, so personal recommendations please.

Basic Backup
Get an external Firewire drive at least equal in size to the internal hard drive and make (and maintain) a bootable clone/backup. You can make a bootable clone using the Restore option of Disk Utility. You can also make and maintain clones with good backup software. My personal recommendations are (order is not significant):
1. Retrospect Desktop (Commercial - not yet universal binary)
2. Synchronize! Pro X (Commercial)
3. Synk (Backup, Standard, or Pro)
4. Deja Vu (Shareware)
5. PsynchX 2.1.1 and RsyncX 2.1 (Freeware)
6. Carbon Copy Cloner (Freeware - 3.0 is a Universal Binary)
7. SuperDuper! (Commercial)
The following utilities can also be used for backup, but cannot create bootable clones:
1. Backup (requires a .Mac account with Apple both to get the software and to use it.)
2. Toast
3. Impression
4. arRSync
Apple's Backup is a full backup tool capable of also backing up across multiple media such as CD/DVD. However, it cannot create bootable backups. It is primarily an "archiving" utility as are the other two.
Impression and Toast are disk image based backups, only. Particularly useful if you need to backup to CD/DVD across multiple media.

Although a USB drive will also work they are much slower than Firewire drives.

Urgent Suggestions needed for best way to solve the problm

Hi Everybody,
I am working on an application which has to graphically show the data in the database. We are using JSP for the front end (the view for the time being will be simple, with text boxes and frames and DHTML) and tomcat as the Server. The data is huge and there ain't much business logic involvd (the user when he clicks on a URL I get the data pertaining to that particular table or column). Now my question is can Tomcat handle such huge data. What do u guys suggest, should I cache data at my server and server to the clients (instead of connecting to the DB for each and every request) If yes, can you guys please suggest a good way to cache data, I mean hat TableModel or HashMap will store data from different tables. Also the DB isn't updated for a while everyday. Also let me know if any of u guys still think a 3 -tier approach is advisable instead of the 2-tir approach
Thanks guys who made it this far

Well, of course a 3-tier approach is advisable. Also, yes, Tomcat can handle what you are doing. As far as caching data on the server, that is going to depend on your database and other requirements. Now about the graphical nature, you aren't going to be able to use JSP to draw graphics. The only way you can do it is to draw the graphics on the server-side, write out JPG files, but then the JSP won't know anything about where the image is, unless you always write the same number of images, in the same place, every time. Otherwise, you need an Applet. Hope that helps.

........ Expert suggestion needed for Loading Data in DB

Hi all
The current requirement we have is to Load data from Excel File to oracle Databases.
The Excel file has around 30 Sheets , each corresponds to a table, ( means 30 tables in the database) .
Currently we are using sqlldr commands to load data from CSV files to the Oracle Database. The only problem is that sometime the DBA has to go out or is busy workign on somthing else, so May i kindy get some expert suggestions on how to automate this DataLoading Task.
Somebody has suggested to My Manager ( who is not aware of oracle and IT at all) that data can be loaded via ODBC. It is suggested to him that all we need to do is to place the CSV files on the Server at a particular folder and Oracle will do the rest.
I am not that proficient in Data loading methods.. so may i know any technique which will simplify/automate the Task.
I mean how can we automate so that every time , the the sql loader scripts run at command promt. I think data base ( Oracle ) as nothing to do with command promt i feel. isnt it ..
Kindly have ur expert./experienced suggestions.
I would be highly grateful to all
Regards

To automate sqlldr scripts, you would usually write a OS script file that will periodically looks for files in a given directory and run the sqlldr commands:
- on Windows: .bat or .wsh files to be scheduled with "at" command or windows scheduled tasks tool
- on Unix: a script shell in the crontab.
Much more complicate but without any OS script:
- write a PL/SQL code to read, parse the file to be loaded using UTL_FILE
package
- this PL/SQL code must also generate INSERT statements and process errors ...
- this PL/SQL code can be scheduled with DBMS_JOB package to run a periodic intervals.

Suggestion needed for processing Big Files in Oracle B2B

Hi,
We are doing a feasibility study for Using Oracle AS Integration B2B over TIBCO. We are presently using TIBCO for our B2B transactions. Now since my client company planning to Implement Fusion Middleware (Oracle ESB and Oracle BPEL), we are also looking at Oracle AS Integration B2B for B2B transactions (On other words we are planning to replace TIBCO by Oracle Integration B2B if possible).
I am really concern about one thing that is receiving and processing any "BIG FILE" (15 MB of size) from trading partner.
Present Scenario: One of our trading partner is sending Invoice documents in a single file and that file size can grow upto 15 MB of size. In our existing scenario when we receive such big files from trading partner (through TIBCO Business Connect - BC), Tibco BC works fine for 1 or 2 files but it crashes once it received multiple files of such size. What exactly happening is Whatever Memory that TIBCO BC is consuming to receive one such big file, are not getting released after processing and as a result TIBCO BC throws "OUT OF MEMORY" error after processing some files.
My questions:
     1. How robust the Oracle AS Integration B2B is, in terms of processing such big files?
     2. Is there any upper limit in terms of size that Oracle AS Integration B2B can handle for receiving and processing data?
     3. What is the average time required to receive and process such big file? (Lets say we are talking about 15MB of size).
     4. Is there any documentation availble that talks about any such big files through Oracle B2B?
Please let me know if you need more information.
Thanks in advance.

Hi Ramesh,
Thanks for your comment. We will try to do POC ASAP. I will definitely keep in touch with you during this.
Thanks bunch.

Suggestions Needed for Wireless Mu

I have not been successful installing the Wireless Music product to my network. I hope someone can offer a suggestion.
I have a Linksys Wireless Router (WRT54G) that I have used for quite some time without problems. It has the latest firmware. I have both B and G enabled, DHCP is enabled, UPnP is enabled and I entered the correct WEP-28 settings.
The latest drivers, utilities and firmware from Creative are loaded on the Wireless Music devices.
During the setup process, the device tries to acquire an IP address for quite some time before the informationless error message appears. (I assume the problem is with IP address acquirement, since it happens after the DHCP wizard screen.
Any suggestions?

Eterry,

Suggestions needed for ADF Faces & JDeveloper 10.1.3.4 af:menu

Hi all,
We are running out space on our top level menu items and was curious if anyone has alternatives for a dynamic menu structure built using JDeveloper 10.1.3.4. Here is what our screen looks like:
Any suggestions are much appreciated.
Thanks,
Wes

Hi again Wes,
If you want to keep using the ADF Faces menus... get a larger screen? :P
Seriously, though, [url http://www.simplica.com/menu.htm]Simplica has an interesting-looking menu component that perhaps you could use (it looks much like the ADF Faces Rich Client menus). I've not tried the components, but have seen them - no idea if they would work "well" with ADF Faces.
Best,

Suggestions needed for Export/Import Business Area Problem

I'm trying to export/import a Business Area from one instance to another and I get the following error during import processes.
Database Error - ORA-00001: unique constraint (EUL4_US.EUL4_EXP_PK) violated
The Business Area I'm trying to import doesn't exists in new instance. During the import wizard I've checked refresh existing object and match by identifiers.
I think my target instance has objects with same identifiers, so I went ahead and changed the identifiers in my source, but still problem persists. How can I correct this error?
Thanks

Did you happen to copy the EUL from one database to another before you were importing/exporting the BA?
Discoverer recognizes EULs using unique reference numbers. However, if you use the database export and import utilities to copy an EUL, the new EUL (including its reference number) will be identical to the original EUL. When EULs have the same reference number, EUL consistency issues can arise if you do both of the following:
* If you modify objects in both the original EUL and in the new EUL
* Having modified objects in both EULs, if you then attempt to copy objects between the two EULs using the Discoverer Export Wizard and Import Wizard (or the Discoverer /export and /import commands)
To avoid potential EUL consistency issues, run the eul5_id.sql script as the owner of the new EUL. The eul5_id.sql script gives a new refererence number to the new EUL and thereby avoids any potential EUL consistency issues.
Reference

Suggestions needed for blackberry 8330 curve

Hi
I have a Blackberry 8330 Curve and am on Verizon. Saturday night my messaging system decided on it's own to separate all my messages. Some of the saved ones I have are now dated 12/5 (were from august!). On top of that when my email is downloaded into my Outlook account the emails are no longer taken off the phone. It is very very hard to open up any of my messages-usually takes 2 or 3 clicks to get them open. Am able to send emails and messages.
Another problem is that I can not update information or comment on people's status on Facebook. This isn't a big problem but is frustrating to me.
I have occasionally been getting this error message: uncaught exception:Java.lang.ArrayIndexOutofBoundsException
I
have rebooted multiple times went to Verizon & this very unhelpful man said all he could do is wipe my phone since there was not a technician there that was proficient on Blackberry.
Any suggestions are welcomed!
Thanks
Kitty

Unfortunately no, the 8330 does not have a wi-fi adapter built into the device. The 8320 does have it however.

Advice needed for 4TB Time Machine Backups

I run a recording studio based around Logic Pro.
I typically have about 7-8 drives online at any given time with around 5TB, but would like to be able to keep more of it active longer. Most of these drives are backed up by Time Machine. But even with 4TB drives I find I quickly run out of space, and have to either delete old TM backups or buy new drives to keep a running TM archive.
While I periodically archive my stuff to optical, and have Backblaze and Dropbox for server space and insurance purposes, neither of those really address the immediacy and convenience of Time Machine for archival retrieval over the course of months or years. And it doesn't help really with boot drive history that doesn't make it to optical archives and isn't kept on backblaze anyway.
So, I have been considering some kind of Raid device, not necessarily for speed or NAS capability (although those might be nice), but mainly to break the 4TB limit and be able to keep my Time Machine growing as a resource for recalling older projects, etc.
It is likely that this will only be used for TM, although I could see potentially partitioning a bit for something else, depending on how big it is. Not sure.
Things which are important:
•Ease of use. Hook up a FW, USB, ethernet, etc. cable, format some drives, and go. I'm not an IT tech.
•$500 or less is preferred
•4 bays would give me room to expand to greater storage, which I think is the only thing that makes sense. might not be enough additional space to justify bothering with a 2-bay, since reliability is at a premium, I'll probably use the most data redundant RAID settings.
•Reliable -- goes without saying
•Hot Swap and Ability to use mixed types of drives - It's not a big deal to keep a spare 3-4TB WD Red on hand, but it would be nice to be able to use whatever I might have handy lying around in case of a failure.
I have heard mixed reviews of Drobo, and better reviews of Synology products, but again, I'm not sure that I really need a NAS--just something simple and reliable--or as simple as something like this can be.
I welcome any advice on what products and brands people prefer for an application like this. Thank you.

Thanks everyone.
These are some good directions to follow.
The issue I think is defining where in the spectum of backup to archival my needs fit.
The thing is, as soon as you go to an array of drives, both the risk and the cost goes up. To my mind, Time Machine is kind of a middle ground between archival and backup. I can make a manual backup quite easily, but TM automates this process elegantly, and gives you date-specific archival up to the point where storage has to recycle. I can also create fixed archives like optical backups of projects and boot clones, which I do every few months. I see those as true archives. But as a result I've accumulated some 3 dozen cheap green HDDs. Many of them archived TM drives. This is a nice safety feature, but it also gets expensive. Being able to go out to double-digit TB in theory with data redundant raids out to 10TB or more by my estimate would give me 2-3 years of instantaneous TM backup. And I've never been able to get more than about 3-4 months of erffective TM for a while now. Meaning I'm buying a new 4TB drive every few weeks to keep up with this.
Maybe I'm just lazy, but having all of my main drives fed into one TM backup is awfully convenient. I don't have to think too much about backups in the heat of my crazy deadlines, libraries and project data constantly changing and being updated, etc.
A Jbod device and a virtual raid as Grant suggested would fill the bill to solve the problem but it makes me nervous, because the possibility of drive failure will be multiplied by the number of drives in use.
What doesn't appeal to me about any multi-drive scenario is that it's putting all the eggs in one basket and making the TM vulnuerable to corruption or being fried because if it gets hosed, I won't have any archived versions other than the array and my sporadic manual archives. I won't be able to go find the single TM archive on the shelf and pop it in anymore to go backwards. Once I become dependent on multiple drive arrays, there is no easy way to rotate backups, and I will have to do other forms of archival more frequently. It's all a risk-benefit equation and there is no such thing as a free lunch, as we know.
The Drobo 5D is beginning to appeal to me because it at least has dual drive failure redundancy and can rebuild even with the loss of 2 drives. I just wish it had more universal approval in the reviews department. Some people love is, some hate it. I would have to really commit to this thing, and fill it to capacity to amortize its cost over a long period of time.
Thanks again for the responses.

good method to link with same table but if 4 subjects only(and must) comes
detail table is not neccessary )
now i am achieving the result by program-coding in C# after getting the rows from oracle
i am using oracle 9i (also ODP.NET)
i want to know how can i get the result in the stored procedure itsef.
2)how it could be designed in any other way.
any help/suggestion is welcome
thanks for your time --Pradeesh

Well I forgot the table-alias, here now with:
SELECT C.COMB_ID
, C.COMB_NAME
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID1) AS SUBJECT_NAME1
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID2) AS SUBJECT_NAME2
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID3) AS SUBJECT_NAME3
, (SELECT SUB_NAME
FROM SUBJECTS
WHERE SUB_ID = C.SUB_ID4) AS SUBJECT_NAME4
FROM COMBINATION C;
As you need exactly 4 subjects, the columns-solution is just fine I would say.

W530 SSD and Memory help needed for high performance systems.

Hi Guys,
After dealing with lots of laptops that got destroyed by daily use, our organizations is considering ordering 25 Thinkpad W530 laptops from Lenovo and we hope that they last a little longer.
Our main usage is video editing and design so we have chosen the best that Lenovo has to offer as far as hardware.
Since Lenovo charges arm and a leg for SSD and 16GB memories, we have decided to purchase these separately and upgrade ourselves.
Knowing the high need for performance, what would you recommend for 128GB SSD and 16GB memory?
The laptops are all coming with 7200 RPM drives for storage so the SSD is mainly for programs and the OS.
For the drive bay, does this part sound right to you? http://shop.lenovo.com/us/itemdetails/0A65623/460/89555ADB1CE946DA80E0E5D6FE77B164
This would be used for the HDD and the SSD would be moved to main HDD location.
Is there anything else we should know about these laptops?
Thank you in advanced for your time and all suggestions are welcomed.
Cheers,
Chris

Help needed for THE decision

Hi everyone ☺
I’m finally planning to start recording what I play, and after some hours of wandering on the web I found some interesting possibilities. Now what I need is to decide which one is more suitable for my needs, and here comes the moment for apple discussions
Basically, I will record my own music one track/instrument at a time (I’m still not able to play more than one…and I dont’ want to spend 2.000$ to buy a 24-ins device just to record drum tracks), I’d like to have a software with built-in effects for guitar/bass/voice, integrated soundtrack possibilities (to play with video recordings), mixing options for both stereo and surround mixing, and I don’t want any card to be placed into my mac. Well, and obviously the sound quality must be pro-like…as anyone probably wants.
So, here’s what I came up with:
a) getting logic pro studio 8 and apogee duet
b) getting pro tools m-powered and mbox 2
c) getting one of the two softwares and a Monster iStudioLink Instrument cable and plug instruments directly into the mac
Now, the questions are:
if I can plug an instrument directly into my mac and control all parameters via one of the two softwares, what do tools like duet and mbox2 serve for?
In the case this tools are useful [ ☺ ], why ☺ … and which is the couple software/hardware that can best suit my needs?
I assume that every software has a proprietary file extension in which audio tracks are saved, so that it should be impossible to record an audio track with one software and edit it with another that has different functions/plugins (ex. from logic to pro tools, from pro tools to cakewalk sonar which I have on a pc etc.). Am I right, or is there any “standard”, non compressed high quality file type in which track can be saved and exported to be edited with different softwares?
I know that from this post it may easily seem that I’m a hopeless digital idiot, but I swear the situation is not really that bad so no need for the kind of explanations with drawings like the ones you find in the “for dummies” guides lol so every experts’ advice will be greatly appreciated
Neptune

Thank you Bee Jay and Pancenter for the lighting-fast and useful answers
now I am aware that an interface IS NEEDED lol (that means they are not produced without a reasons, are they?). I know Pro Tools is the industry standard but I don't like anyone/anything to tie me to their choices/interests (so that's why I was asking about Pro Tools, knowing that there's some sort of "hardware threat"). What I look for is just quality and if I understood what you both mean, as far as this aspect is concerned, Logic and Pro Tools are substantially comparable...isn't it? On the interfaces side, I already checked the Saffire ones (they seem quite good, and cross-platform use is definitely a plus), I will check the others mentioned and will let you know In fact, I didn't consider the "platform problem" but, as I wrote, I also own a PC with an Audigy 2 soundcard (midi/analog/optical/digital inputs/outputs and firewire port...not Madonna's private studio, but not as sad as Mac's little hole) and Sonar 6 Producer Edition, so that has been a really good point to ponder. And now, in the middle of this software/hardware battle...any personal suggestions based on tests/personal experience?

I can't download the apps with big size like need for spees, but in apps with normal size(less than 100KB)there is no problem,is there any body who can help me?

I can't download the apps with big size like need for spees

Have a little patience. 4 minutes is only a short time for someone to find your post and reply to it. Also clicking on "This Solved My Problem" marks your problem as solved so many folks that may otherwise help will pass the question by since it is "solved."
I suggest you start a new question that gives a good title to a specific problem. Then in the body of the thread describe the problem in detail, tell us what steps you have tried so far to correct the problem, what happened, and what error messages you received.
