Trouble booting CentOS after installing 10g XE

After tackled with XE on Window XP and 10g DS, I moved on to Linux. I installed CentOS 4.2, and everything seemed to work fine. Then I installed 10g XE with Start XE when CentOS boots up. Everything seemed to be fine, and I was able to login through the XE home page as system. Then I turned off the computer and went to sleep. Next day when I started the computer, my CentOS wouldn't boot. It stopped after:
Checking SWAP Spaces [OK]
The cursor was blinking...forever! The sad thing was I had to switched the power off to stop everything. I am a newbie to Linux. Did I miss something? Somebody help please?!

This doesn't really mean there is a problem with the swap space. When linux startup process hangs at enabling swap space means next step (database startup) is hanging. It is just about to open the graphical console, but it freezes at this point because it is not able to startup oracle.
When installing, did you perform the execution of '/etc/init.d/oracle-xe configure' as the root user to configure the database?
You can still enter into your linux environment, as by now the networking settings are already active. So open a session by means of ssh or telnet if available and verify this startup phase. Just as a workaround, look for the /etc/init.d/oracle-xe file that was created by the XE installation. Rename it and set just an empty file instead, so you are able to open your console. Once fixed, rename it back to its original name.
In case of boot problems, use your rescue disk, mount your root file system and perform the outlined steps.

I don't run CentOS (but I admire this OS as being one of the best). When your boot-screen comes up, I assume it offeres you a choice between Cent and Windows. However does it ALSO offer a choice for Cent in "safe mode" or "rescue"? If so pick that and see if you can at least get into CentOS.
One note... on a lot of Linux systems they set the 'timer' on the boot screen to like 5 seconds... meaning if you don't make a choice it boots to the default (usually the first choice.) The way to stop the clock is to use the down-arrow key immediately when you see the boot-screen pop up.
Or it may look like this:
http://www.idevelopment.info/data/Oracle/DBA_tips/VMware_Workstation_50/images/create_vm_centos_enterprise_linux_ICENTOS_1.gif
and you have to hit a F key. Select "resuce' or "safe" etc. if given a choice. Hitting any F key should stop the timer.
There must be a Red Hat guy on this board that can give more info since CentOS is RHEL without the logo and a few proprietary modules.

My Windows 2000 machine has trouble booting up after instaling PCI-6503 card

After I installed the card in my Dell Desktop has trouble booting up. I have to pull the power cable out and then reconnect for it to come up.

Hello;
The best way to go about that is to completely uninstall the NI-DAQ driver you have installed on that machine, turn the computer of and remove the board from it.
You then reintall NI-DAQ, and put the board back. If the same behavior shows, the best bet is to search for some other peace of Software/Hardware currently installed on the machine that might be conflictant with NI-DAQ.

has anyone's screen go blank and not boot up after installing the new yosemite OS

Hi Mofimac,
Thanks for visiting Apple Support Communities.
If your Mac is only starting up to a blank gray or white screen after updating OS X, you can find some useful troubleshooting steps in this article:
Mac OS X: Gray screen appears during startup
I recommend going through these first three sections first:
Disconnect, test peripheral devices and network cables
Perform a Safe Boot
Reset the NVRAM / PRAM

Anyone have trouble with IPad3 after installing OS6.1.3? keeps crashing

Anyone having trouble with iPad3 after installing OS6.1.3? Mine keeps crashing.

Mine seems to be just fine.
Try a reset,
Reset your iPad by pressing the 'Sleep' and 'Home' button at the same time for about 15 seconds or so. Your iPad will then go through a reset / reboot procedure and will be ready for use within about a minute.
Don't worry about doing this as you will not lose data or settings.
Good luck and do report back.

Cannot connect to database after installing 10g

Hello friends at www.oracle.com ,
after installing Oracle 10g, I am trying to use programs like SQL*Plus or Forms Builder. However, these programs are asking me for the host string, and:
- I cannot simply ignore this question, because I cannot connect without this information.
- But I don't know how I can configure a host string for local access.
- And I don't know if there's already a default host string for me to use after installing Oracle 10g, because I have no practice in database configuration, since I'm a developer.
Please help me.
Best regards,
Franklin Goncalves Jr.

Hi ,
Few pointers which may help you , but a small caveat all instructions pertaining to way we do internally in oracle , so there could be some mismatch at customer end , but more or less logic should be same , in case you can't any step revert back :
1. When Db asks you for connect string essentially it asks for the complete description of the db to connect including :
Db server machine name / ip - that can be resolved from your system if it's a remote server .
Username , Password ,
Db Instance Name - TnsAlias mentioned in TnsNames.ora .
Now there are few Env. variables that you need to set before running / starting an oracle db instance .
1. Oracle_Home - Essentially Oralce Installation directory .
2. Oracle_sid - unique identifier for Oracle Instance .
3. For OracleDb only set T_Work and TNS_ADMIN env. variables as %Oracle_Home%\work directory and place your Listener.ora file in that folder .
4. Make your initial parameter file init<Oracle_Sid>.ora in %Oracle_Home%\database -- default location .
5. Create Oracle Instance specific services to run on a Windows machine , essentially they will be two and default nomenclature is :
Oracle Service - OracleService<Oracle_Sid>
Listener Service - Oracle<oracle_sid>TnsListener
Now in %Oracle_Home%\bin directory you have couple have tools to help you in whole process including lsnrctl.exe , tnsping.exe , sqlplus.exe .
and onec you start oracle instance like this :
SQlPlus "/as sysdba" -- OS Authentication
--- Connected to Idle instance
Sql> startup --> this will take default parameter file
Check out dump location for log and trace files generated if enabled .
Now client setting :
1. This is the place where you need appropriate connect string with all components as mentioned above .
Check out any good site for exact syntax , but you need to make sure regarding client you are using for e.g:
ODP.Net , Java Driver etc .
For Client few important settings :
Execution directory should contain tnsnames.ora
Create T_WORK and TNS_ADMIN for execution directory .
check out for listener connectivity using :
tnsping <TnsAlias>
Imp -- Include all relevant stuff in System PATH for execution from anywhere .
Once it connects tehn you can use appropriate username / password for connecting with appropriate connection string .
Normally while installing oracle you would have set the username and password to be changed later .
or otherwise onec you log in as sysdba, you can create new username/password and give it sysdba permissions .
Also imp. thing for connecting from a remote system is having Sqlnet.ora authentication file in client's T_WORK and TNS_ADMIN .
I hope it helps upto some extent .

Trouble viewing PDFs after installing Mavericks

Prior to installing Marvericks, I had no trouble viewing the PDFs on this site:
http://dhrd.hawaii.gov/state-hr-professionals/class-and-comp/
Scroll to bottom and click on Class Specifications and Minimum Qualfiication Requirements.
An excel spreadsheet is downloaded.
Open the spreadsheet and click on the link for any PDF.
It seems that after installing Mavericks, the documents open but the text is unreadable.
I tried removing the PDF viewer internet plug-ins from the library as one member had recommended for a similar issue, but that didn't work for me.
Anyone know how to resolve this issue?

deleted.
I just get the giberish when I open your PDF reference.

Slow Booting time after installing MacBook Pro EFI Firmware Update 2.0 on 13 Inches Mac 2010 model

I'm experiencing a slow boot time after my computer installed a MacBook Pro EFI Firmware Update 2.0 itself on 13 Inches 2010 model, how to downgrade or fix it?
My computer is starting 2 times slower then it should be, why Apple done this to me?
Please help who really know somthing about Macs.

I have the same problem, especially when I open my laptop from sleep. It takes at least 2 minutes for the computer Internet connection to work.
Never had that problem prior to the last firmware update 2.7.
Is there a way to revert back to 2.6?

Why does my iMac shut down before it can boot up After installing 7.3 update on my iMac?

After installing 7.3 last night, I hit restart and went to bed. My intel iMac i7 3.4ghz was powered down this morning, and only after unplugging,waiting, rep plugging,
It finally powered on, only to boot to the gray apple screen, go black and silent. (this exact issue had me lugging it back to apple a month after purchase, today is 93 days)
Recovery mode got me about one second further in bottling up before shutting off.
I was forced to upgrade from an unproblematic pc g5, after iCloud, so do not own snow leopard and was told I would never need a re install disc.
Has anyone having the powering off during boot after updating to 7.3?

omg. I would copy and paste your original post to the iMac section. You're talking about a fine piece of equipment, the Intel iMac i7 3.4ghz , and you should not be having such problems. Maybe others in the iMac i7 community might also have some ideas.
Re: the safe boot. That's good that it worked. This is fairly new and very, very helpful with a dead computer because at least you can get to Safari, get to the Internet and get ideas and seek help.
But why did it shut off after a while? That's not right. No reason it should have done that.
From something you said I would worry about your power supply problem or this PerIphrEa. I don't know what that is but Migration is built into Lion OS, no? Third party perificials (or apps) can certainly cause conflicts and not work as well as advertised.
Also, seriously, I would get some tape, like duct tape, and tape up that loose power supply.
Why do you need something extra for your migration? (Or is the reason your old PowerPC G5 needs to run Lion but it can't?).
If that is the problem, here's an idea. Continue the canibalization of your PowerPC G5, take out it's hard drive(s). Buy an 'enclosure' to put the hard drive in and allow you to connect this hard drive to your new machine, the beautiful iMac i7, using the old hard drive as an external drive.
I did exactly this with my old PowerPC G5, using this enclosure, a Macally G-S350SUA, info at: http://www.macally.com/en/product/ipod4show.asp?ArticleID=215
I now use this for my Time Machine backups.
Re:What is the proper amount of time the computer needs to be unplugged? This would worry me. I turn off my comuter NOT by unplugging it but by holding the power on button for about 3-4 seconds and then it turns off.
I then wait 5 long seconds before pressing the power on button again to turn the computer back on.
Having to plug in and unplug and plug in and having to wait ten minutes for it to work is not normal.
Is there a power supply issue in your home, perhaps?
Considering the value of this machine and the fact that it may still be under warrenty, I'd consider the weeklong diagnostic. Would the machine have the same need to wait ten minutes to turn on at the Apple place?
What if you plug it in at a friend's house, or an office or library? Would it still take ten minutes before you could turn the machine on?
It might seem horrible to have to wait a week...or to do this again and again but I'd recommend taking full advantage of your warrenty, keep sticking this problem back to Apple and insist it gets made right. It will be worth it in the long run.

Hp Pavilion HPE PC H8-1214 won't boot up after installing a Western Digital External hard drive

I just recently installed a 3TB Western Digital External hard drive to use for backing up photos and since then I am now having problems with my computer.
I will turn the computer on, but nothing happens. The power button lights up, but the small stack of CD's that would normally light up on the front, while it is powering on, does not light up. My monitor screen just stays blank and nothing happens.
If I turn off the desktop and unplug the external hard drive from the USB, let the the PC sit for 30 sec to 1 minute and then power it back on, it works properly.
PC is an HP Pavilion HPE PC h8-1214
Product #: qw701aa#aba
Running Windows 7
Any advice would be greatly appreciated.

Thank you for your reply. I'll answer one at a time:
During these times when the computer seems to turn on but doesn't load Windows, do you get any type of image or error on the screen? Nothing appears on the screen at the time of boot. I don't even see the 'HP' logo or BIOS prompt.
Have you tried switching the power cable or testing the power cable in a different wall outlet (especially if it is plugged into a power strip, try it directly plugged into the wall). Yes I've plugged it into multiple outlets with and without surge protection with multiple power cables. The power supply doesn't seem to be the issue as it engages all fans etc.
If you've tried a known good power adapter in a known good outlet, it may be an issue with the power supply or a loose connection inside the computer (RAM, power, video card). I've re-seated all components, cables etc to no avail. I'm reasonably experienced in IT support and have never experienced an intermittent problem such as this.
The PC has been plugged in since I made my original post on 02/23/13. Each day I've powered it up to see if it would boot and had been unsuccessful. This evening, I walked by and hit the power button and instantly the drive 'disk' lights lit up, keyboard and mouse lit up, and it booted successfully (after 10 days of no luck). Now I'm afraid to shut it down b/c I never know when it will boot again. There are no system errors and it's running without any issues - until I shut it down again. The IT support guru's at my place of employment feel like it may be an issue with the motherboard since I don't see a bios prompt when this issue occurs. The unfortunate part is that I bought this re-furbished and the HP 90 warranty has expired...
Any further advice or troubleshooting assistance would be greatly appreciated!!

OSX cannot boot-up after installing Security Update 2008-008

Hi Everyone.
I'm using a MacPro 2 x 2.66Ghz Dual Core Intel Xeon with 3GB RAM with Tiger 10.4.11.
After installing Security Update 2008-008, my OSX was not able to boot-up. The screen shows the Apple Logo and the spinning grey gear wheel. It stayed that way for several hours.
I finally switched it off and re-installed OSX 10.4.8 using the Start-up disk that came with my MacPro.
Now I've updated the OSX, all the software & updates EXCEPT Security Update 2008-08. My MacPro works fine now.
Was Security Update 2008-008 the cause of this problem ?
Sincerely,
Azman

Was Security Update 2008-008 the cause of this problem ?
Probably not directly. Very likely something was not quite right on your computer before the update and the update happened to exacerbate that. A number of people feel that optimizing the maintenance of your computer before doing the update and doing the update under controlled conditions minimizes problems.
There's been recent discussions as to what steps are truly necessary in doing a minimal problem update.
I think #1 to which all agree is to make sure you have a backup of your computer in case you do need to back out of it again.
Some like to boot from their installer discs or an external backup and verify (and if necessary repair) their internal drives as well as drive permissions. This is done with Disk Utility.
You can also go to the step of booting into safe mode to do the install.
I like to download the update onto my computer and install it from there rather than let Software Update do it. I know a few people who had problems with doing the update via software updater found a manual install to work.
Repair permissions again afterward.
It also helps to only install one update at a time and to run the computer for a while to make sure it is behaving well.
Almost all of the above steps (except backup) have been questioned as to necessity because probably many people have done successful updates without doing them. I say they can't hurt, they can very likely do good (especially if your computer isn't regularly maintained), so why not do them to be safe.

How many of you trashed Boot Camp after installing it?

The challenge is over. After installing and playing with windows on a Mac, I'm going to get rid of it. I feel like I'm at work when using it. Good god windows is ugly and uninviting. And that sound, that familiar windows is booting sound is enough to make me barf. The main problem is dual booting, maybe I'll try Parallels desktop when it becomes available. BTW, anybody know how to properly uninstall Boot Camp?

Actually it's working fine for me. Since I'm in a long transition process of going from Windows to Mac this is the perfect solution for me - one computer instead of two. Half the cost the way I see it. The only problem I ever had was with the Mac keyboard uninstalling itself on the Windows side intermittently - sometimes once an hour and sometimes every couple of minutes. Turns out it is a Mac issue either with the USB ports on the iMac or the keyboard itself not having enough power. Two solutions: 1) use a Windows keyboard, or 2) use an AC powered USB hub and plug the Mac keyboard into it.
Cheers!

Unable to launch oracle applications after installing 10g Express

I installed 10g express to be able to access the database using a client (TOAD). Now I am unable to launch the oracle applications. I am able to login but once I select a responsibilty and function java never launches. Any suggestions?

Hi,
could you please let us know more about where you installed express database and why your applicatin is not working?
But lets say if you have installed express database on your laptop and on your application is not launching, then problem could be with your application and browser. There is no connection between client and oracle application client.

Troubles with Ipod after installing new software

After installing the new software on my Ipod Mini 4GB, it won't charge, or at least, it sais it won't.
I have a USB power adapter, and I charged my Ipod all night. This morning, I STILL got this
http://www.sharksdiest.com/stephane/ipod.jpg ...
I already tried to reset the Ipod several times...I tried to connect it to my PC (Windows XP), but also that didn't work, so I can't install other software.
Does anybody thinks he/she has a solution? Should I go to the store (I already send them an e-mail several minutes ago). Or is my Ipod dead, and should I buy a new one?
Thx for your help

Usually this is because the activation server is temporarily unavailable. Try again in 20 minutes or so.
