Problem:
An administrator installs an application on the server.
Other non-administrator users are unable to run the application.
References:
http://technet.microsoft.com/en-us/library/ee791868(v=ws.10).aspx
Problem:
Application locker is to restrictive
Solution:
Adapt the permissions of the program and probably the folder.
a. Program Permissions
windows-run : secpol.msc
Select Application Control Policies > AppLocker
Create a new rule in the Executable Rules for the program.
b. set sharing of files/folders permissions.
Some programs require access to the file folders or to specific files.
Click on the file/folder and in the context menu select "Share".
Add the correct users or groups and set the permissions to read/write according to the requirements.
Win Server 2008 r2 - iPad rdp connection to server
Problem:
When connecting via an RDP client app on iPad, you get the message "The requested session access is denied".
This connection is possible when connecting as an Administrator user but not as a 'normal' user.
Reason:
Most clients connect to the console by using the /console option, which is only possible for administrators.
Solution:
Found an iPad app that contains the option to define a connection to the server with the option not to specify /console : 2X (website www.2x.com)
Create a profile to connect via a specific user and in the profile of the server the last option is "Connect to console" which has to be set to Off.

OEL - VBox Guest Additions
On gui-less linux installations it is not always clear how the guest additions can be installed.
This article tries to show how to do this.
The steps to do this are:
The cdrom will become attached to the vm
Best is to reboot the system at this instance. (Have encountered that for some reason the cd device was no immediately available.)
Mount the cdrom by using the following command:
mount /dev/sr0 /mnt/cdrom0
So ... that is why 0 at the end ... ;-)
The output of the command will be something like this:
root@wlspfrd mnt]# mount /dev/sr0 /mnt/cdrom0
mount: block device /dev/sr0 is write-protected, mounting read-only
Go to the cdrom drive:
cd /mnt/cdrom0
[root@wlspfrd mnt]# cd /mnt/cdrom0
[root@wlspfrd cdrom0]# ls
32Bit runasroot.sh VBoxWindowsAdditions.exe
64Bit VBoxLinuxAdditions.run VBoxWindowsAdditions-x86.exe
AUTORUN.INF VBoxSolarisAdditions.pkg
autorun.sh VBoxWindowsAdditions-amd64.exe
To install the additions execute the VBoxLinuxAdditions.run command.
./VBoxLinuxAddtions.run
In a 64-bit Oracle Linux environment you will encounter a problem which is indicated by the line:
Building the main Guest Additions module [FAILED]
The reason is that the build requires the header files of the correct version of the Linux OS.
The line preceeding the FAILED error gives a clear hint:
The following command should solve the problem.
yum install kernel-uek-devel-2.6.32-200.13.1.el5uekPut the package name, in this case kernel-uek-devel-2.6.32-200.13.1.el5uek in the copy buffer
To install this package, the yum repository must be configured (context Oracle)
See the website for this: http://public-yum.oracle.com/
Follow the instructions.
cd /etc/yum.repos.d
for Oracle Linux 5:
wget http://public-yum.oracle.com/public-yum-el5.repo
for Oracle Linux 6:
wget http://public-yum.oracle.com/public-yum-el6.repo
In the obtained file enable (value = 1) the correct version (warning if you enable the latest version the update may take a long time ... ).
After installation of the yum repository, retry the installation of VBox additions.
This should now succeed.
After this any shared folder will become available in the /media directory.
When using version 6 update 3 of Oracle Linux, it seems not possible to get the correct Kernel headers for the uek. At least it should be possible to find them ... but I did not find them, or at least ... not as fast as I wanted. Just used a short-circuit to get things working fast ...
Even though the kernel was booted with the compatible version (RHEL) the openGL compilation failed. All major requirements like folder sharing and screen sizing do not work.
Found on a site the hint to do an export MAKE="/usr/bin/gmake -i " before launching the VBoxLinuxadditions.run command.
This solved immediately the problem of the shared folders not being accessible under /media/sf_*.
It did not solve the problem of the windows resizing.
After a reboot with the original UEK kernel (in OL 6.3) which caused the Shared folders not being accessible anymore.
Starting to update to really latest version of OL v6 ... see if things will be more smooth then ...
... and yes it did.
So ... changed config file in the yum.repos.d directory to retrieve the latest versions, which at this moment in time seems to be 6.5.1. Performed a simple yum update which took 40 MB to download and install. Rebooted with the new kernel.
Mounted the cdrom again and started the installation of the VBoxGuestAdditions again.
This time no errors were encountered ... with the exception of the Window System Drivers.
Will try to fix that too.
Good Luck
This article tries to show how to do this.
The steps to do this are:
- Get the additions mounted (supposing no cdrom is attached yet)
- create cdrom directories
- determine the cdrom device
- mount the device loosely
- install the guest additions
- (Install missing packages ... )
- (Retry installation)
The cdrom will become attached to the vm
Best is to reboot the system at this instance. (Have encountered that for some reason the cd device was no immediately available.)
To be able to mount the cdrom within some instances you will require a directory to mount it to.
Go to the /mnt directory as root user and create some directories with a trailing number.
For example:
mkdir cdrom0
mkdir cdrom1
...for as many as you will find cdroms required ;-)
The trailing number starts best with 0 ... why ... see later.
Determine the cdrom device.
The name of the device depends under which link the cdrom is attached.
If a cdrom is defined as a SATA device the cdrom will become available as sr0, sr1 ...
For the further documentation let 's suppose the device is /dev/sr0
Go to the /mnt directory as root user and create some directories with a trailing number.

mkdir cdrom0
mkdir cdrom1

Update dd 02-feb-2014
When using version 6 update 3 of Oracle Linux, it seems not possible to get the correct Kernel headers for the uek. At least it should be possible to find them ... but I did not find them, or at least ... not as fast as I wanted. Just used a short-circuit to get things working fast ...
I followed these steps:
- boot with the non-uek kernel
This can be achieved by: - or change the kernel at boot time
- or change the default boot instance in the /boot/grub/grub.conf file
- Make sure gcc and the kernel-devel packages are installed (using yum install gcc kernel-devel kernel-headers)
- running VBoxLinuxAdditions.run -> this should not fail anymore
- you will find in the /media any shared folder
- now ... reboot in
- uek -> seems to work ... but not really guaranteed because of the difference in the compile-time and runtime-kernel versions
- run in the version as was compiled
- make the kernel version permanent in the grub.conf if not already done so
Update 4-feb-2014
Context Delta : Oracle Linux 6.3 base installation with Database Server option.Even though the kernel was booted with the compatible version (RHEL) the openGL compilation failed. All major requirements like folder sharing and screen sizing do not work.

bash - Substitution of variables
This link explains variable substitution in the Bash Shell.
For convenience a copy of some info in that post:
For convenience a copy of some info in that post:
- ${VAR-default}
If VAR is set (to any value, even null, then return $VAR, otherwise return the default value provided. VAR is unchanged. If the - is preceded by a colon (':') then the default value will also be returned in case the value of VAR is null. - ${VAR=default}
The same as '-' except that the value of VAR will be changed too. The use of the colon is the same in this case. - ${#VAR}
This returns the number of characters in VAR. (Unicode ???) - ${VAR#pattern}
Returns VAR with the shortest instance of pattern removed from the front.
Pattern is not a regular expression but a glob. If ## is used instead of # the longest matching pattern is removed from the front. - ${VAR%pattern}
Identical to # except the front will be the end of value of VAR
Installation of Forms on OEL r5 u5
This post is currently only a wrap up of links I found interesting in installing the forms environment.
Envirionment:
Two hosts: one ... a vmware environment with oracle VM Manager the other with Oracle VM Server.
Next to these I have a NAS which is used to provide the software to all guests on the VM server for sofware and other feeds (a Thecus N5500 with 10TB disk capacity) (NFS is choses over iSCSI because the fact that iSCSI has to be considered as a hardware layer and is therefor dedicated to one controlling machine. Because I want to use it on all machines ... I had it configured as a NFS share)
The VM server has an Intel i7 920 processor with 6GB of ram and 4 TB of disks installed (Acer brand)
On the VM Server the following guest systems will be installed:

The VM server has an Intel i7 920 processor with 6GB of ram and 4 TB of disks installed (Acer brand)
On the VM Server the following guest systems will be installed:
- db server: OELr5u2 with Oracle DB 11g, running with 2 cores dedicated and 1.5 GB ram.
- wls admin server: OEL r5u5
- hosts to run managed servers: OELr5u5, initially only one server, with the intention of running 4 managed servers.
- Later on the host with managed servers will be copied to try the concept of clustering ...
The network ... well very simple ... all hosts will get a fixed ip address within the same subnet.
Since the virtual NIC's are on the same physical system, they use the softnetworked network ... which provides rather high speeds.
Software
The following software is used:
Oracle VM Manager r 2.2.0
Oracle VM Server r 2.2.0
VMWare Fusion (is used to create a linux vm and install the VM manager in it) running on Mac OS X.
Oracle Enterprise Linux r5 u 5.
Weblogic server 11g r1 (10,3,3,0)
FMW - portal, forms, reports and discoverer v 11g r1patch 1 (11,1,1,2)
Patch to FMW - portal, forms, reports and discoverer r11g r1 (11,1,1,3)
For convenience a VM with DB11g.
Installation of the Virtual Machines
To be done
Installation of FMW on the server
Install the WLS server.
Install release 11,1,1,2 of FMW-PFRD
Install on top of that 11,1,1,3 (this is a pure patchset ... big but a patchset)
That's it for now ...

Android - Copy Nokia Contacts to Android Phone
In this link you can find the HowTo on how to do this.
In case the link wouldn't work anymore here's how:
In case the link wouldn't work anymore here's how:
- on the nokia go to contacts and mark all the contacts.
- Copy all contacts to the inserted microSD card
The phone will ask to replace all existing contacts on the card. Confirm yes. - Connect to the MicroSD card. This can be done by browsing the card after connecting it through cable or bluetooth to a computer or by simply inserting the MicroSD card into a expansion to SD card.
- Copy the contents of the contacts folder to a local folder. (I'm assuming you're a wise person and using a Unix based OS such as Linux or Mac OS X.
- Create a single file from all the vcf files by using the command cat *.vcf > MyContacts.VCF
- Now you need a Google account ... Android is based on Google and ... they seem to work very well together (See later)
- Go to the contacts and simply import the MyContacts.VCF file into the Google Contacts.
- Now you can modify the data as you require (merge them, clean them out and so on ... )
- Now ... in case you had already defined a Google connection on your phone ... you will be amazed but ... all your contacts will be present on you phone ... be amazed by it !!!
In the other case, simply connect from the phone to your newly created google account ... and also in this case ... be amazed by the wonder of integration!
OpenOffice - Mailmerge and blanc pages
When performing a mailmerge sometimes a blanc page gets inserted.
When searching for this problem on the internet you will surely find this solution which suggests to set the insert blanc page when printing to off.
That solution is a workaround which has to be set in a document. It controls the fact that if a previous section ends on an odd page and the next section starts on an odd page, when printing an even page gets inserted, which is used when printing in duplex/double sided. In a mail merge this section end by default generates the 'even' page and by this the blanc page ...
The problem basically comes from the fact that while doing a print mailmerge to a new single document every instance of a record will be printed to a new section which starts on the odd page. You will notice this in the line starting each printed instance which is in fact a section break.
So you should be able to control the behaviour of the 'section printing' in the document.
This link shows the wiki page on sections in OpenOffice.

Google - Hoe meer efficient zoeken
Het zou bijne common knowledge moeten zijn ... maar door de sturing van de zoekmachine van google is het soms gemakkelijker naar een meer relevant resultaat te komen.
Het is interessant om een keer door deze lijst te gaan kijken en een keer alle mogelijkheden te doorlopen.
Het is nog handiger om deze lijst bovenaan uw bookmarks te houden omdat het dikwijls zo zou zal zijn dat je meer tijd wint door een betere zoekopdracht te geven dan door een eindeloze lijst van niet-relevante zoekresultaten te lopen.
