Oracle ORA-28000 Account is locked

Hi All,

This was the solution for me

su - oracle

sqlplus "/ as sysdba"

sql> alter user system account unlock;

--> System was my locked user, in your case replace system with you locked account user name. 

Hope it helped,

Fedora 22 VirtualBox


I have installed the latest fedora 22 and from some reason VirtualBox gave me tons of errors.

Looked all over the place and didn't find any good solution till now. So i wanted to share this with you to save you time, hopefully that you are seeing before all the searches i already did.

This is the required things to do:
This was my error

WARNING: The vboxdrv kernel module is not loaded. Either there is no module
         available for the current kernel (4.1.6-201.fc22.x86_64) or it failed to
         load. Please recompile the kernel module and install it by

           sudo /etc/init.d/vboxdrv setup

         You will not be able to start VMs until this problem is fixed.

 First , try to run this, with or without sudo
"/etc/init.d/vboxdrv setup"

if it went ok -> you are all good, probably virtualbox will run ok for you, for me it didn't helped.

If it didn't went ok, go over here :
I got this error
Stopping VirtualBox kernel modules                         [  OK  ]
Recompiling VirtualBox kernel modules/etc/init.d/vboxdrv: line 335: /var/log/vbox-install.log: Permission denied
  (Look at /var/log/vbox-install.log to find out what went wrong)

So i did as they say : "cat /var/log/vbox-install.log"
And got this:
Makefile:185: *** Error: unable to find the sources of your current Linux kernel. Specify KERN_DIR=<directory> and run Make again.  Stop.

So i did the following:
"sudo usermod -a -G vboxusers username" (you will replace username with your name of the user)
"su -"
" KERN_DIR=/usr/src/kernels/username" (replace username with your name of the user)
"export KERN_DIR"
"dnf install open-vm-tools"
"dnf -y install kernel-devel kernel-headers"
"sudo /etc/init.d/vboxdrv setup" -> this should be running ok now
You should receive something like me
Stopping VirtualBox kernel modules                         [  OK  ]
Recompiling VirtualBox kernel modules                      [  OK  ]
Starting VirtualBox kernel modules                         [  OK  ]

Good luck and hopefully that i helped a bit,

The BPEL process deployment session is already active.

Hi All,

Happens with Oracle Service Bus and Eclipse.

I have found, that stopping coherence and osb and then starting coherence and starting osb solved for me the issue.

Hoped it helped,
