Any Experiences with OODBMS and WLS (also Javlin or VEJB)

Hi guys,
we are evaluating WLS in combination with OODBMS and RDBMS. Has anybody
done this before and want to give us some hints on it. We take a look at
Versant and Object Store versus Oracle 8i. We have to build a high
traffic site with approx. 1000 hits/sec. We intend to modell the
business logic in the EJB Modell. We have to present product-infos, news
etc from a database. There are to pretty new containers out there :
Javlin and VEJB(Versant). Has anybody experience with these products ?
As I learn from this newsgroup there seem to be some performance
problems regarding Entity Beans. I would like to know if this problems
occur with OODBMS or RDBMS or both. Is the Container the bottlenack or
the database ? It seems that from the performance point of view
stateless Session Beans with pooled jdbc-Connections are the best
solution. Is this right. Has anybody put in Java-Instances right in an
OODBMS without involving a container ? What experiences have you made ?
Thanks for your help
regards Oliver

Oliver,
I suggest contacting the ODI or Versant folks. They can provide a wealth of
benchmarks that explain why they're up there in performance with RDBMSes.

Does anybody have any experience with keyloggers and a good program to detect one on your mac? I think I may have one.

So yesterday I found out that my email address password had been changed. I don't remember doing this, but it is possible I changed it a while back and considering I keep my email constantly logged in. But at the same time, two of my apps were trying to access their "store". I play a game called League of Legends, which has an online store, and it randomly came up with the message "Could not connect to Maestro" (credit card). Then, Itunes (which I rarely use) came up with "sorry, we could not continue with your purchase". I think it's very strange that all of this happened at the same time, but hopefully it's a case of a forgotten password and two games bugging/crashing. I scanned my entire computer with iantivirus and it hasn't found anything, but I've heard keyloggers can be a bit hard to detect. Does anybody have any experience with keyloggers and if so, what program did you use to detect and destroy it?

If you think that a keylogger has been installed the only safe thing you can do is erase your drive and reinstall.
I don't think that is the case however.

Any experience with Paralles and Windows XP Pro? Advise?

I am new in Mac world. I understand Parallels software will let you install windows on a HD partition.
Any suggestions to make this process as expedite as possible?
How big is the partition required?
Is it possible install windows based aplications on that partition? software?

I have a core 2 Duo (3.33) iMac with 8GB and run Parallels 7 with a Windows 7 operating system. I use it for surfing the web and Microsoft business applications. I find no problem with heat and speed. For everything else, I use OSX.
I was using the same product/operating system on a MacBook Pro (2005) Core 2 Duo with 8GB of RAM and had no difficuties either.
THe problem with Bootcamp is you have to reboot your machine to switch between OSX and Windows. That was a killer for me. In addtion, with Parallels, you can drag files accross platforms if necessary.
I haven't tried Fusion. You can download a trail of Parallels and see how you like it before you commit to a purchase. There are online sales from time to time and you can buy the product for less than $40.00.

Has anyone had any experience with iDVD and latest release of iMovie?

Trying to get latest version of iMovie (version 10.0) burned to iDVD. Any help is greatly appreciated!

Go to File>Share>File, choose the size (probably should choose either SD or Large) then click Next, give it a name, then click Save.
Go to iDVD. Go to File>Import>Video and select the file you just created. It will bring the video into your iDVD project.

Do I need to run and anti virus program with MAC OSX Lion? Have heard different opinions!
You will continue to hear different opinions here, where thoughts range everywhere between "anti-virus software is the evil spawn of Satan" to "anyone not running anti-virus software is a fool."
Truth is, this is still a very personal decision on a Mac. Depending on circumstances, it is still very easily possible to stay safe without using anti-virus software, but circumstances and personal preferences vary widely. Besides which, anti-virus software cannot even remotely provide you a guarantee of protection!
To learn how to stay safe (with or without anti-virus software), and how to decide whether to use anti-virus software, see my Mac Malware Guide.

I have paid and downloaded LION and want to update my IMAC, can i just run install and it keep photos settings etc from Snow Leopard or is a full reinstall with wiped hard drive, anyone have any experience of this and do i need to run a backup beforehand?

Always backup your important data before upgrading to a new Mac OS X.
Lion doesn't erase the drive but better to be safe than sorry.
And run Disk Utility (Applications/Utilities). Verify and if necessary repair the startup disk before upgrading.
Using Disk Utility to verify or repair disks
Before upgrading read here > Lion upgrade questions and answers: Apple Support Communities

Anyone got experience with Filemaker and Mac OSX v10.4 on a G5

I am in the transition period from PPC to Intel, and installation of Aperture. My main box is an Apple G5 DP running OSX 10.3.9 and I have the upgrade software to go to OS 10.4+ but have not yet installed it. I also have a recent Intel MacBook Pro running 10.4.9.
Problem I'm experiencing is not unusual. If I run the current OS I cant run Aperture in the G5. If I upgrade the OS I suspect I will 'leave behind' some of the other software I rely on.
My query is about one main piece of software I use - Filemaker Pro 5.5 which runs a database I created handling my analog image collection, client info, deliveries and invoices, accounts etc. It works cleanly and quickly and allows great flexiblity in preparing material for output.
I downloaded the trial of Filemaker Pro 9 and it didn't like my old database when I tried to import it into the Intel laptop, and many functions seemed to have gone awol in the conversion to the newer software.
I cant experiment with this in the G5 as Filemaker is a key management tool in my work and any complications I need to overcome will impact seriously on my work.
So my question is - anyone got any experience with Filemaker in G5's - if I go to OSX10.4 upwards on this non-Intel machine will Filemaker V5.5 still run? And if not, are there any ways around this - eg using Classic environment?

*"I go to OSX10.4 upwards on this non-Intel machine will Filemaker V5.5 still run?"*
Yes

MY BAD EXPERIENCE WITH CHAT AND VISION

In my personal e-mail I received publicity inviting me to purchase a Skype credit gift card. I thought it was a nice offer and I happened to have a friend that had the need and could use such a gift. I procedeed to purchase a $10 dollar gift card, I did the transaction from Colombia and sent it to my friend in the US. Shortly after the purchase I received a message warning me that my order was being under security scrutiny. I found it unexpected and unjustified (Is my $10 dollar order a security risk of some sort?), but I thought that maybe it was because it was an international order, and I understand the need for security in online transactions, so I decided to not worry, trusting in the spotless service that I have had from Skype up to that point. At that moment I noticed that the one providing the service was no Skype but Chat And Vision (whose website, by the way, looks far less friendly than Skype's).
Then I received an Email telling me that the order has been rejected. No justification, no explanation. Just a politely worded but most unhelpful and uninformative e-mail. It made a point of telling me that they didn't retain the payment, yet my card was charged and no refund has been made so far. I replied the e-mail asking for a reason, and how to get a refund. I received the automated reply telling me that somebody would contact me the next day. It's been a day and no reply so far.
Searching online I found mine was only one in a long list of blunders and poor service from Chat And Vision. The complains on forums and online outnumber the claims of good service. Mine is a very small case compared to other complains I have read about. It was a small purchase for a smal amount, but it turned into an unexpectedly unpleasant experience for something that should have been a simple purchase ( Am I really such a security risk that I can't be allowed to place an order for a gift card?)
In the end I feel that I was snared into a trap with that offer. I trusted, I paid, didn't receive the goods, haven't yet received the refund, my friend really needed that gift and had to do without, which caused him inconvenience, my high regard from Skype has been tarnished, and I'll hesitate to make new purchases of Skype services in the future, if they keep being powered by Chat And Vision.

Some updates: I received two e-mails from Chat And Vision, regarding my two questions as to why my order was rejected and how to get my money back. These are the answers:
The first one (Ticket ID: PBF-650-80186), says: "Thank you for your email. Firstly, apologies for the inconvenience this may have caused to you. Unfortunately, due to security reasons I am unable to divulge this information. However, should you wish to make another purchase with us again, we will try to process your new order instead".
Polite but uninformative. Notice that beyond an unfocused general apology it does not acknowledge any problem nor does pledge any improvement, just a vague statement that they may allow me to use it's service again if I choose to try (not exactly reasuring).
A second answer to a second e-mail says: (Ticket ID: SVN-701-71147) "Thank you for your email, please be assured the money will be refunded back to you."
That's all. Again polite but no useful information, just a vague assurance of refund, somehow, someday into the indefinite future. If it happens I'll post it here but I'm not holding my breath.
Reading other answers from Chat and Vision posted online here and on other forums dealing with their service, there appears to be a pattern of politeness, vageness, refusal to acknowledge problems and absence of a pledge to improve. Their costumer care seems designed to placate the user without promising to get better, and is so devoid of helpul attitude that it makes me believe that their messages are redacted by a software program, and consumer complains never reach any administrative person. I might be wrong but the doubt has been sown which is a shame. Up until now I was very vocal on my praise for skype, recomending it to family and friends as a very useful and good service, but this experience with Chat and Vision, and my discovery of their costumer service history online, has set me thinking about looking for alternatives to Skype, and certainly has dissuaded me to recomend Skype to anyone ever again,or at least while their sales are still managed by Chat And Vision, or at least while Chat and Vision continues its customer service attitude, polite on the surface but haughty and unhelpful underneath.
If there are new updates I might post them here, but for now I will not pursue the matter further since the amount involved was small and I see no point in sending more e-mails to Chat and Vision. I just feel bitter that the great service that I felt was Skype has ben tarnished by this experience. Just some final thoughts:
I do not complain that my order was scrutinized by security reasons, I understand the risk of illegal activity on online transactions, and the need of online companies to be careful, but the process Chat and Vision used seemed overly unconcerned for the confort of the consumer. It took around a full day for my order to be scrutinized and then rejected, which did let me for a long time in the dark not knowing if my gift would reach the friend I wanted to give it to. This is 2014, does Chat and Vision not have the tecnology to do a better and faster process? Do they scrutinize online orders by hand? I have read more cases similar to mine here on this forum, which to me implies that Chat and Vision are overly and unnecessary zealous on their security procesess. ( Also it is jarring that they seem to consider their clients to be criminals, for no reason at all and with no opportunity to contest the charge.)
If they are going to reject a transaction on security reasons, why not do it before the payment is processed, not after, which can be stressful to the consumer that gave the money and didn't receive what was advertised, for no real reason. Seems to me there is a mistake in the way the system is set, or there is a clear disdain of what the client might think or feel.
I think that's all. Thank you if you went all the way thru this overly long rant. If you are a consummer beware that when you buy services from Skype, you are not buying from Skype but from somebody else and that somebody else does not have a spotless record. If you are an administrative person from Skype or Chat and vision, I hope you eventually prove me wrong about your unconcern for the welfare of the consumer. My experience so far is not encouraging but that may change.
Have a good one.

Any experience with coolbook?

Does anyone have any experience with coolbook on the Macbook unibody? I am constantly running mine with one proc full out for hours on end and noticed that the CPU is at 80 C and the fans are at about 2.5k, so I figure if I could under volt a little I could get the CPU temp down a little. Pushing the fans up seems like a bad idea to me because that ages them faster.
Also, the idea of being able to keep the processor's speed down when I am not plugged in sounds good to be because I am almost never doing anything that I care to do quickly.
Also, does anyone have an experience with coolbook and apple care? i.e. getting heck from Apple b/c it was installed?

Hi Paul Bailey,
I just bought Coolbook for my 15' Macbook Pro Unibody (2.4ghz) yesterday. I recently asked your very question about Coolbook and warranty / AppleCare and the response I received from iVmichael was that it would be fine (thread visible here: http://discussions.apple.com/thread.jspa?messageID=10132068&#10132068 ). I read the Coolbook instructions yesterday and it said that Coolbook couldn't damage your processor. I did some experimenting with it and even putting the highest speed at the lowest voltage it would let me use on Coolbook only resulted in a kernel panic which just told me to turn the computer off, which I did. When I turned it back on, there were no problems at all so I don't think you'll run into problems with Coolbook or at the very least, that's been my experience.
I played around with the voltages a bit however I found that for most things I do, it didn't make a noticeable difference. I mostly just use my Macbook Pro for web browsing and email, which are already very well handled at cool temperatures by Apple.
I think the one thing to keep in mind is that even if by lowering the processor speed you're able to use less power through undervolting, you'll then end up with the processor working more time (eg. 2.4ghz processor will finish an encoding job much faster than a 1.8ghz processor) and that higher speed processor might actually end up being a better fit because once it finishes the demanding tasks, it'll underclock itself while the slower Coolbook-enabled processor is still working at most likely a higher frequency + voltage.
From what I've read, everyone's Macbook Pro will have different results with Coolbook, as some of the Intel chips are willing to run (and be stable) at lower voltages than others, so some people will get more (or less) benefit than I experienced. I was able to get mine to run at 2.4ghz while using 1.0625 volts instead of the default of 1.1375 volts, so my CPU is running about 7% more power efficiently now. I had similar power efficiency improvements experimenting with different speed/voltage combinations. One thing to watch when lowering voltages is that some people have experienced a Core getting disabled (because not enough power is flowing to keep both enabled). If lowering the voltage causes this, you might find your Macbook Pro getting hotter instead of cooler, especially if doing anything that on one CPU causes it to constantly work at it's maximum performance.
I'm not sure how much of a difference +7% CPU power efficiency would make in battery life, however mine seems to run about 2-3 degrees Celsius cooler which is nice, although it wasn't bothering me at the higher temperature. What I've heard mentioned in other threads on the Apple Discussion forums is that a cooler running Macbook Pro's battery should be able to go through more charging cycles than a warmer running one because of the effect heat has on the duration of a battery's life, so that's another definite plus.
For battery life, you should get a pretty good extension (better than Coolbook) by lowering the Macbook Pro's LCD/LED brightness to the minimum or as low as you can tolerate if you aren't doing that already. I've heard that even not having the keys backlit when on battery power can add about 45 minutes to battery life as well. For the $10 Coolbook costs, it's worth it in my opinion.
As for experimenting with fan speed, I definitely think it's a bad idea to have the fan running at max speed or ramping it up substantially over the default Apple settings. Like you said, it'll make the fan age faster and I've heard replacement fans aren't all that cheap (especially when you factor in labor). I really wouldn't know the answer to this, so I'm just speculating, however I personally would see fan failure resultant from smcfancontrol (or another fan speed program) as the Macbook Pro owner's fault and clearly not the fault of Apple if the fan were to fail because it's being used for extended periods of time at substantially higher speeds than it was intended to run at. I've seen some people say it wouldn't affect the warranty, however I think it's best that you contact AppleCare directly and ask just to be safe if this is something you're considering doing -- I haven't managed to come across an official answer from Apple.
What I think is a good idea would be to increase the minimum fan speed a bit. My Macbook Pro fans usually run at around 2000rpm, so by increasing the fan speed to 2200rpm, I make it run a bit cooler while presumably not doing much to shorten fan lifespan. I may perhaps even be increasing fan lifespan as it now takes longer before the fans need to run at a higher rpm because they're doing a better job at keeping the Macbook Pro running within it's designed thermal envelope.

5300 RAM showing up as 3200 in Quad, any experience with this problem?

Hello, just received a 2 gig kit for my G5 Quad (2 - 1 gig sticks from Crucial). System Profiler shows it's speed at 3200, lower than the original 512 RAM which is 4200. Crucial says it will only reach 4200, but why is the new RAM showing up at 3200? Tried removing original RAM and only using the new, same speed displayed - 3200.
Has anyone had any experience with this oddity? Any idea if the RAM is not performing or the Mac is not giving accurate speed data?
Thanks, Steve

Memory identified as PC2600 in MDD
Symptom
Apple Hardware Test identifies the computer's memory as "PC2600" rather than "PC2700".
Products affected
* Power Mac G4 (Mirrored Drive Doors)
* Apple Hardware Test version 1.2.6
Solution
There is nothing wrong with your computer's memory. This issue is addressed in Apple Hardware Test 1.2.7. If you have version 1.2.6 and are experiencing this issue, contact AppleCare for a replacement disc.
Apple is aware of that. It first showed up in 10.3.0 and has been there ever since. The issue with the above DDR2 is I think different and unique.
With the MDD, Apple used Micron in the system I got, and I added Crucial. Both show up as '2600.'

Hello Danno ^^¿''
Well, I just bought the RS480M2-IL with a Venice 3000+ and 1 GB DDR, I've tested the Video onboard(all the newest drivers installed) with the 3DMARK 2001, and I just can get 3052 ptos...so .. please tell if you has made some time ...and how's your score?
Oh man please tell me...maybe I made a bad choise but I was specting something better from this Mobo!!!...
thanks and enjoy the time
PD: Another thing: my modo comes with the bios ver. 3.4 ...and have "The Normals falis" son I don't really know wich ver, could be better....cya..

Any experience with logitech v400 cordless laser mouse?

I'm still looking for a good mouse, either bluetooth or USB-cordless for my iBook. I recently learnt that Logitech has a new notebook mouse: logitech v400. If anyone has experience with this mouse I would appreciate hearing their findings.
thanx, Frank
iMac G5 1800 mHz & iBook 12' (1,33 mHz, 60 GB) Mac OS X (10.4.3)

Nick it's a USB. I have the MX1000. As I told Frank I really don't have any experience with the others so I couldn't really say. I went from the Apple one button to an Microsoft Intellimouse. I realized I liked all those buttons. A lot! So when I decided on getting a wireless I wanted one that had plenty of buttons!
The MX1000 had just came out and was getting real good reviews and I checked one out and liked it so I asked Santa for it last year and I must've been a good boy because my wife.... I mean Santa brought me one.
I would imagine you could check into exactly what feature each one has and find one you like.
I really like the idea of never having to put batteries in it. It charges off the base/receiver. Mine usually lasts about 3 weeks between charges and it takes about 4 hrs to charge it. It has a batter meter on it so I know ahead of time when it's low and I usually just put it in the charger overnight.

Any experience with refurb iMacs?

Howdy all...
Wondered if anyone here has any experience with purchasing refurbished units from the apple.com store site? There seem to be a few deals there, and they do offer applecare, just wondering if maybe that's where all the lemons end up?
Any experiences at all would be great to hear, and don't need to be limited to iMacs... just really interested in the refurb experience as a whole.
Thanks,
adam

I bought a refurbished BlackBook at the end of June and it arrived in absolutely perfect condition - it even smelled new.
Refurbs are a great value. You get a discount, the full one year warrantee, and the ability to extend that to three years with AppleCare. For all intents and purposes, Apple treats it like a new unit.
I have even read here about people getting "free" upgrades with refurbs. Apple advertises the base configurations and ships out whatever they have in stock. Sometimes that means a larger HD or more RAM, but do not count on it. I would hold off on ordering RAM or a larger HD until you actually receive it to see what it comes with.
