I need to run periodical task, how can I do so?

I have an application running in BEA Weblogic Server, it's a portal application in fact.
I log every login try to my portal.
My next task is too make summary of the data I've collected (every 24 hours).
So I would like to run some task every 24 hours.
What can I do in Weblogic?

You could use JMX timers, for example or EJB 2.0 Timers.
Check out -
http://e-docs.bea.com/wls/docs90/jmxinst/timer.html
and
http://java.sun.com/j2ee/1.4/docs/api/javax/ejb/Timer.html (you probably want to look this one up elsewhere as well)
cheers,
Deepak

I am running out of memory on my hard drive and need to delete files. How can I see all the files/applications on my hard drive so I can see what is taking up a lot of room?

Either of these should help.

Or search 'disk size' in the App Store.
Be carefull with what you delete & have a backup BEFORE you start, you may also want to reboot to try to free any memory that may have been written to disk.

My MacBook Pro is running really slow - how can I fix it?

my MacBook Pro is running really slow - how can I fix it?

Things You Can Do To Resolve Slow Downs
If your computer seems to be running slower here are some things you can do:
Start with a visit to: OS X Maintenance - MacAttorney.
Boot into Safe Mode then repair your hard drive and permissions:
Repair the Hard Drive and Permissions Pre-Lion/Mountain Lion
Boot from your OS X Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
Repair the Hard Drive - Lion/Mountain Lion
Boot from your Lion Recovery HD. When the recovery menu appears select Disk Utility. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported, then click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the main menu. Select Restart from the Apple menu.
Boot to the Recovery HD:
Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
Restart your computer normally and see if this has helped any. Next do some maintenance:
Suggestions for OS X Maintenance
For situations Disk Utility cannot handle the best third-party utility is Disk Warrior; DW only fixes problems with the disk directory, but most disk problems are caused by directory corruption; Disk Warrior 4.x is now Intel Mac compatible.
OS X performs certain maintenance functions that are scheduled to occur on a daily, weekly, or monthly period. The maintenance scripts run in the early AM only if the computer is turned on 24/7 (no sleep.) If this isn't the case, then an excellent solution is to download and install a shareware utility such as Macaroni, JAW PseudoAnacron, or Anacron that will automate the maintenance activity regardless of whether the computer is turned off or asleep. Dependence upon third-party utilities to run the periodic maintenance scripts was significantly reduced since Tiger. These utilities have limited or no functionality with Snow Leopard or Lion and should not be installed.
OS X automatically defragments files less than 20 MBs in size, so unless you have a disk full of very large files there's little need for defragmenting the hard drive. As for virus protection there are few if any such animals affecting OS X. You can protect the computer easily using the freeware Open Source virus protection software ClamXAV. Personally I would avoid most commercial anti-virus software because of their potential for causing problems. For more about malware see Macintosh Virus Guide.
I would also recommend downloading a utility such as TinkerTool System, OnyX 2.4.3, or Cocktail 5.1.1 that you can use for periodic maintenance such as removing old log files and archives, clearing caches, etc.
For emergency repairs install the freeware utility Applejack. If you cannot start up in OS X, you may be able to start in single-user mode from which you can run Applejack to do a whole set of repair and maintenance routines from the command line. Note that AppleJack 1.5 is required for Leopard. AppleJack 1.6 is compatible with Snow Leopard. There is no confirmation that this version also works with Lion.
When you install any new system software or updates be sure to repair the hard drive and permissions beforehand.
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. Carbon Copy Cloner
2. Data Backup
3. Deja Vu
4. SuperDuper!
5. SyncTwoFolders
6. Synk Pro
7. Synk Standard
8. Tri-Backup
Visit The XLab FAQs and read the FAQs on maintenance, optimization, virus protection, and backup and restore.
Additional suggestions will be found in Mac maintenance Quick Assist.
Referenced software can be found at CNet Downloads or MacUpdate.
Additional Hints
Be sure you have an adequate amount of RAM installed for the number of applications you run concurrently. Be sure you leave a minimum of 10% of the hard drive's capacity as free space.
Add more RAM. If your computer has less than 2 GBs of RAM and you are using OS X Leopard or later, then you can do with more RAM. Snow Leopard and Lion work much better with 4 GBs of RAM than their system minimums. The more concurrent applications you tend to use the more RAM you should have.
Always maintain at least 15 GBs or 10% of your hard drive's capacity as free space, whichever is greater. OS X is frequently accessing your hard drive, so providing adequate free space will keep things from slowing down.
Check for applications that may be hogging the CPU:
Open Activity Monitor in the Utilities folder. Select All Processes from the Processes dropdown menu. Click twice on the CPU% column header to display in descending order. If you find a process using a large amount of CPU time, then select the process and click on the Quit icon in the toolbar. Click on the Force Quit button to kill the process. See if that helps. Be sure to note the name of the runaway process so you can track down the cause of the problem.
Often this problem occurs because of a corrupted cache or preferences file or an attempt to write to a corrupted log file.

You do not really need to defragment your drive. And, see:

Hi Amanda,
Software applications are usually installed in the Applications folder on the Macintosh HD and are accessible to all users.
I would advise you to check the Applications folder and see if your software is in there.
Next step would be to Control Click or Right Click on the application and choose "Get Info" and make sure the permissions are set to "Read & Write" for all users. The article below provides more details:

You may need to contact Adobe Support if this does not resolve your issue:

Gratuitous kernel panic on my iMac G3 running Tiger. How can I prevent this

Ok, I know I probably shouldn't have installed Tiger on my G3 iMac so you don't need to remind me. However, it runs pretty good and I hardly ever even see the beachball spinning when I ask it to do something. What I am shocked, shocked by is the ridiculous amount of frequency that I end up with a kernel panic that gives me the 'gray screen' telling me I have to restart my Mac. I have been able to keep this down to a minimum by pointedly only running programs and commands one at a time with a good sized pause in between but even with that I am diappointed with how often it happens. Call me a heretic, but I think it would have killed Apple to stick with their classic OS framework rather than go to UNIX. I would like some tips about things I could do to minimize this occurence above what I already do. It really ***** to have had to reinstall Tiger about 3 or 4 times since I upgraded and have to change up the screen position, dock, desktop, mouse, screen saver, and reinstall all my programs after my iMac has croaked and finally accepted another reload of Tiger.

I'll ignore the major portion of your post which comes across as a rant and try to stick with the title: "kernel panic on my iMac G3 running Tiger. How can I prevent this?"
Kernel panics are usually caused by bad or marginal RAM or RAM that isn't seated properly, or by buggy or damaged software or drivers. In the past, problems with marginal RAM for Macs has shown up when people upgraded to new versions of the OS -- which might fit your situation.
Although your CPU is slow, you have lots of RAM, so Tiger should run OK, if the RAM is not defective. You don't mention how much free space you have on your hard drive. Typically you're going to need at least 5 Gig free to give Tiger breathing room.
Running a system maintenance utility like Yasu would probably also be beneficial:

What does the hardware test for your Mac say about your system? This might help us determine if there is a hardware cause for the kernel panics.

Also, does reinstallation takes the back up automatically or the files will be lost. Please help.

Here are a bunch of scripts to get folder size under all circumstances. Take your pick.

I have Time Machine that I used to back up my old computer. It was running snow leopard. My MacBook died, so I got a new one which is running Lion. how can I restore the data from the time capsule to my new Mac?

In technical support, sometimes you have to make educated guesses. I'm sorry that you were offended.
iTunes does prompt when it is going to erase a device, and the message is clear.
She said in her message that she was able to successfully sync the old ipad. This indicated to me that itunes wiping the data was not an issue, because either it had been setup at the apple store (in which case it doesn't actually wipe the ipad despite saying it will*) (*based on a single case I saw), or because the itunes media folder was migrated.
Furthermore, my solution was to tell her how to backup her ipad (by either doing it manually, or as a last resort, by deleting the corrupt backup -- that she couldn't access anyway.)
I got that last part of the instructions from the "Taking Control of your iphone" book which I found samples of when I did a google search for "corrupted backup itunes".
She marked this as a solution, so it worked for her.

I have Adobe Photoshop CS5 installed in two computers. The hard drive of my home computer crashed and I had no time to deactivate the software. The hard drive needed to be formatted. How can I activate the software CS5 again ? Thank you for an answer.

I have Adobe Photoshop CS5 installed in two computers. The hard drive of my home computer crashed and I had no time to deactivate the software. The hard drive needed to be formatted. How can I activate the software CS5 again ? Thank you for an answer.

If it's the same computer, same CPU and same HD, no de-activation or re-activation should be necessary.
Install from scratch and apply all updates manually.
Please do a forum search. I and others have repeatedly answered the question about failed updates of CS5 a whole bunch of times recently.
Bottom line: the Adobe auto updater is utterly useless in CS5 and prior versions. You need to download the updates and apply them manually yourself.
I and others have even supplied the links for Mac and Win, which you haven't even bothered to specify.

There is no serial number and you don't need one. What you need for a subscription is to SIGN IN within Acrobat, so it knows the subscriptions you own.

For MS Visio (any version) only the appropriate version of Acrobat *PRO* provides PDFMaker for Visio.
For Visio 2013 specifically you must have Acrobat XI Pro (updated to at least 11.0.1).
