Is it good to have a lot of memory heap?

Hi!
I have a java applications that makes transactions. I have
configured 256 MB of heap memory. But when the
java process carries "n" transactions, it is going
very slow. However I have changed to 128 MB of heap memory and
I haven't had any problem with the java process.
Why with 128 MB it's ok and with 256 MB not?
Does anyone know anything about this?
Thanks

The version is java 1.2.2_07.
But I think that the garbage collection (gc) works in this way.
I mean if the memory heap is very high the gc java 1.2.2_07. doesn't work until the memory heap has been completed and when this happen the gc begins to free memory heap. I think that this situation can happen always and at this moment the java process will run very slow. But I am not sure.

I have Garageband version 4.1.2 (248.7) installed on my early 2008 IMAC Version 10.5.8. I have never upgraded but have a LOT of projects. If I upgrade my operating system to the next level (10.6?), will my GB version still work? Do I need to upgrade GB?

I have a LOT of projects involved and hope they will transfer. Can I (and should I) upgrade GB at the same time and how far should I go with that without causing a problem with my projects? What would I gain if I upgrade GB? Thanks!

v4 is pretty lonh in the tooth now, and GB only costs $15, so I'd think it's a good idea

the only version you can buy new is v6,a nd it should open older projects without issue ... however you could keep 4 around:

I have a lot of movies on my computer and need to free up memory. What is the best solution, if I think I may need these movies in the future?

I'm an elementary music teacher and my students perform regularly so I have a lot of their performances on my computer. Now I need to free up memory so am wondering what the best solution would be, given that I may need access to these movies again in the future.
I do have an external hard drive, but have never been able to figure out if you can store movies on it, instead of on the computer hard drive.
Thanks so much!

Good evening,
I see you have another post about deleting movies and iDVD projects. Wanting the video to be available in the future is a significant criteria because video files are very large and are very compressed to fit on a DVD. If you want the video to be available in the future for additional editing (eg, highlights of the year), ideally you'd want to save the video in a format which will easily allow this. To me, this suggests you delete the iDVD projects but keep the iMovie files for future editing. This accomplishes the easy editing objective but keeps a lot of large files on your hard drive (each iMovie/iDVD project will be about 20% smaller -- assuming a 4 to 1 compression).
If you are willing to accept some additional work in the future and are okay with some reduction in video quality, you can pull sections from an existing DVD and use iMovie to combine them. The extra work is required to decompress the DVD, and this is also the reason for loss of some sharpness. This strategy reduces the file size of your combined projects by about 80% if you save disc images (virtual DVDs), or if you save the physical DVDs, you save 100% of the space.
I'd decide about the tradeoffs before jumping into action.

When i try to download mavericks i can't . it said that i need at least 2 Go of memory but i have a lot. What to do?

Also, if you really do not know or sure of what you are doing,
Before embarking on a major OS upgrade, it would be wise, advisable and very prudent if you backup your current system to an external connected and Mac formatted Flash drive OR externally connected USB, Thunderbolt or FireWire 800, Mac formatted hard drive. Then, use either OS X Time Machine app to backup your entire system to the external drive OR purchase, download, install and use a data cloning app, like CarbonCopyCloner or SuperDuper to make an exact and bootable copy (clone) of your entire Mac's internal hard drive.
This step is really needed in case something goes wrong with the install of the new OS or you simply do not like the new OS, you have a very easy to return your Mac to its former working state.
Then, determine if your Mac meets ALL minimum system install requirements.
To install Mavericks, you need one of these Macs:
iMac (Mid-2007 or later)
MacBook (13-inch Aluminum, Late 2008), (13-inch, Early 2009 or later)
MacBook Pro (13-inch, Mid-2009 or later),
MacBook Pro (15-inch or 17-inch, Mid/Late 2007 or later)
MacBook Air (Late 2008 or later)
Mac mini (Early 2009 or later)
Mac Pro (Early 2008 or later)
Xserve (Early 2009)
Your Mac also needs:
OS X Mountain Lion, Lion, or Snow Leopard v10.6.8 already installed
2 GB or more of memory
8 GB or more of available space
Next,
If you run any older Mac software from the earlier PowerPC Macs, then none of this software will work with the newer OS X versions (10.7 and onward). OS X Snow Leopard had a magical and invisible PowerPC emulation application, called Rosetta, that worked seamlessly in the background that still allowed older PowerPC coded software to still operate in a Intel CPU Mac.
The use of Rosetta ended with OS X Snow Leopard as the Rosetta application was licensed to Apple, from a software company called Transitive, which got bought out, I believe, by IBM and Appe could no longer secure their rights to continue to use Rosetta in later versions of OS X.
So, you would need to check to see if you have software on your Mac that maybe older than, say, 2006 or older.
Also, check for app compatibilty here.

If you have any commercial antivirus installed and/or hard drive cleaning apps installed on your Mac, like MacKeeper, CleanMyMac, TuneUoMyMac, MacCleanse, etc. now would be a good time to completely uninstall this apps by doing a Google search to learn how to properly uninstall these types of apps.
These types of apps will only cause your Mac issues later after the install of the new OS X version and you will have to completely uninstall these types of apps later.
Once you have determined all of this, you should be able to find the latest version of Mavericks by clicking on the Mac App Store icon in the OS X Dock and then login to the Mac App Store using your Apple ID and password.
You can then begin the download and installation process of installing OS X 10.9 Mavericks from the Mac App Store.

Mac and Mac models are picky about the RAM the Mac needs to see and use.
As you have found out, the 1067 speed RAM will not work in your year and model iMac.
You need the 1333 speed RAM.
If, you can return the RAM for a refund, do it!
If not, try online Mac RAM source and seller Crucial memory. They have a table that matches your Mac to the correct and reliable RAM. You may need to contact them to see whether or not they ship to South Africa, though.
If Crucial dpesn't work out, here's the specs for your year and model iMac that you need to seek out and purchase.
Maximum Memory
32 GB (Actual) 16 GB (Apple)
Memory Slots
4 - 204-pin PC3-10600 (1333 MHz) DDR3 SO-DIMM
Good Luck!

No way around this. Your phone has to be restored using a computer running iTunes. Make an appointment at an Apple Store to have your device examined by a technician. Or contact Apple Support.

"Your email account" means to tap on the name of your email account. Whatever it is listed as in the settings.
In my mail settings, one of my email accounts is a Comcast account. I tap on the Comcast name and it brings up this window.
Then I tap on the arrow under the Outgoing mail server smtp setting to get to the next window.
In the resulting window, I then tap on the arrow next to the smtp server under the Primary Server setting.
That brings up this window in which I check to make sure that my user name and password have been entered correctly. If those items are missing, enter them in the appropriate fields and then tap done.

Is it good to have more key fields in DSO

Hey Guys ,
is it good to have more key filds in dso , and how will it impact the performance of Loading/Access.
Anurag

The objective of using key fields is to recognize each data record uniquely. So, if we can achieve this by small number of key fields we should go for that.
        Technically if we use many key fields that will create data redundancy. Besiseds that primary index will be bigger.
        Also we cannot use more than 16 key fields.

       thanx.

I have a lot of money on my Apple ID but when I try to buy something it ask for my security questions that I do not remember the answers to. I also don't have access to the email I used to set up my Apple ID but I do know the password how do I fix this ?

You need to ask Apple to reset your security questions; ways of contacting them include phoning AppleCare and asking for the Account Security team, clicking here and picking a method for your country, and filling out and submitting this form.
They wouldn't be security questions if they could be bypassed without Apple verifying your identity.

I need to configure Acrobat to display PDF files in Safari, but I have a lot of troubles to do it.I have OX S yosemite, I unistalled adobe acrobat, I closed safary and I installed the new version of adobe acrobat.

Dear everyone
I need to configure Acrobat to display PDF files in Safari, but I have a lot of troubles to do it.
I read a european commission document explaining that
http://ec.europa.eu/research/participants/data/support/sep_usermanual.pdf
If Safari does not display pdf forms in the browser window, uninstall all older versions of Adobe Reader and download the most recent one. First close Safari and then install Reader. Launch Safari and you ought to be able to open the pdf files inside the Safari window. If you install Adobe Reader 10.1.x without first closing Safari, Safari will not display the pdf file inside its browser window until it is re-launched. For further help, please see http://helpx.adobe.com/acrobat/kb/troubleshoot-safari-plug-acrobat-x.html
I have OX S yosemite, I unistalled adobe acrobat, I closed safary and I installed the new version of adobe acrobat
but when I open a web page that I need to allow me to display and modify PDF files it is not working.
I checked the following web page
Troubleshoot Safari plug-in | Acrobat X, Reader X
that is recommending the following:
The AdobePDFViewer plug-in is used to display PDF files in Safari using Acrobat and Reader.
This plug-in is installed as part of the Acrobat X or Reader X installation. The location of this plug-in is:
/Library/Internet Plug-ins/AdobePDFViewer.plugin
but after the new installation with this folder is completely empty and I am still
unable to open these pdf.
Does anybody knows anything else I can do?
Best regards
Ramon

You don't. Apps are permanently tied to the ID used to purchase them. Instead of creating a new ID, change the primary email address on your existing ID.

I have a lot of music on my ipod that was placed there from CD i own. Now, I can't transfer that music to my iphone because it wasn't purchased through itunes. Is there a way around this?

I have a lot of music on my ipod from CD's I own. I want this music on my new iphone 4s. Because music was not purchased via itunes, it will not allow me to transfer the music. Is there a way around this?

You can transfer music imported from cd's to your iphone. This has never been a restriction.
You are having a problem in your individual case.
Have you tried basics fro the manual? restart, reset, restore.
