How should I try out Oracle Grid and Oracle database?

I want to try out Oracle Grid and Oracle database in a virtualized test environment. I have already downloaded the Oracle VM VirtualBox for Windows platform. The OS for the production environment is RHEL. So, do I just need to download Oracle Linux? How about the VM Manager, VM Server, and Oracle programs?

You can use the standard distribution media from http://www.oracle.com/technetwork/indexes/downloads/index.html and https://edelivery.oracle.com/linux to install Oracle Linux and Oracle 11g in Virtualbox. Virtualbox can use real disk media as well as .iso disk image files. Oracle Linux 6 is not certified for any Oracle database product yet. Your best option will be to install Oracle Linux 5.7 and then install the Oracle-Validated software package to prepare Oracle Linux for the Oracle database installation.
Virtualbox and Oracle VM are different products. Oracle VM, including OVM server and manager installs its own operating system and is designed for installations on bare metal machines. Virtualbox is an application that requires a primary host OS, e.g. Windows, MacOSX, Linux, to install one or more virtual machines with Windows or Linux guest systems.

How do you try out an application and keep $HOME clean afterwards

As a new Gnome user, naturally I turned to evolution for an email client well integrated with Gnome. As it turned out, I couldn't find any love for it, so I removed the package. But the problem was that it left behind in several places stuff I no longer wanted.
I had prepared for just that. During the try-out of evolution, I had inotify monitor the files it laid its hands on:
$ inotifywait -mr -e CREATE -e MODIFY -e DELETE ~
The list I got from this:
create ~/.pki/nssdb/{cert9.db,key4.db,pkcs11.txu}
create ~/.config/evolution/*
create ~/.local/share/evolution/*
modify ~/.config/dconf/user
modify ~/.local/share/gvfs-metadata/home*
add password to ~/.local/share/keyrings/login.keyring (gnome-keyring)
download mails etc. to ~/.cache/evolution/
Obviously the cleanup was not as easy as simply removing files/folders, I had to:
clean up dconf database:
$ dconf reset -f /org/gnome/evolution/
$ dconf read /org/gnome/desktop/notifications/application-children
['gnome-network-panel', 'nautilus', 'evolution']
$ dconf write /org/gnome/desktop/notifications/application-children "['gnome-network-panel', 'nautilus']"
$ dconf reset -f /org/gnome/desktop/notifications/application/evolution/
clean up login password stored in gnome-keyring: install and run `seahorse', delete the entry "Evolution Data Source XXXXXXXXXX.XXXX.XX@hostname".
clean up data and config:
$ rm -rf ~/.cache/evolution/ ~/.local/share/evolution/ ~/.config/evolution/
I don't know about the NSS stuff, but since no other applications seem to use it (IIRC NSS is used by Chromium, which I don't use), I simply remove it all:
$ rm -rf ~/.pki/
gvfs metadata stuff I really don't know about; ignoring.
As you can see, It takes some long hard work to simply try out an application like evolution while keeping my $HOME intact.
I imagine I could have tried it out under another user (correctly named "tester"), or maybe used some kind of filesystem snapshot (which ext4 lacks afaik), or some kind of sandbox. Too much hassle maybe?
My question to you is how do you do a throw-away trace-free test-run of an application?

lolilolicon wrote:@firecat53, I'm not sure I understand (I don't have an idea of the tools you just mentioned), but I feel that virtual machines seem to be overkill/over-complicating? For trying out they may be very suitable, but for daily use they don't seem to be very convenient.
Heh, to me having to mess with dconf databases and moving $HOME seem way more complicated!
So if you just do a quick Arch install into a virtual machine (you can expedite it by mounting a shared directory and sharing/copying your /var/cache/pacman/pkg directory to avoid re-downloading all your installed packages). Configure it as you wish. Now create a shapshot of the virtual machine as it now exists. This is almost a one-click operation in Virtualbox. Now you have a 'saved state'. Boot up the VM, install the package you want to test...change things, break things, whatever. When you're done, shutdown the VM and select the option to 'Discard current state' or some such. Now the VM reverts back exactly to how you set it up originally. Keep it updated just like your regular system (or in whatever state you need for testing) and snapshot it after an update. You can discard old snapshots when you're comfortable with your current update.
The other other tools I mentioned are just tools that can deploy and configure multiple virtual machines (for example for developers to be able work collaboratively in identical environments). Probably overkill for what you need.
I think you will spend less time getting a suitable test VM configured then you will trying to worry about filesystem snapshots and monkeying with environment variables. Just my two cents

How to clone 11gr2 grid and oracle homes

Hi,
By mistake I have installed the software and the database under the same disk /u01. I should had installed the software under /u02 and the database + grid infrastructure for standalone server + Oracle restart under /u01.
My database is 11gR2 on Linux Redhat server.
I have installed Grid Infrastructure for standalone server and the database in /u01.
How can I clean clone all these components from /u01 to /u02? I mean the components are:
- Grid Infrastructure for standalone server under grid user.
- Oracle Restart under grid user.
- Oracle software and Oracle database.
Thank you

What about desinstalling everything : grid infrastructure, Oracle restart , Oracle homes, databases.
I have seen some users of this forum complaining of the errors from the de installer.
can I simply use the Deinstallation Tool downloaded from the OTN and then in ORDER:
1- Remove the Oracle database home under Oracle User:
./deinstall -home /u01/app/oracle/product/11.2.0/db_1
2- Remove the grid install under the grid user:
./deinstall -home /u01/app/11.2.0/grid
Any idea please?
Thank you

How do I find out the version of Oracle Time Zone files?

Hello there,

How do you edit out the date and time stamp from a photo

How do you edit out the date and time stamp from a photo

You can blur it out with retouch
The built-in "Retouch" brush in "Edit" mode should suffice, if the background is mostly uniform, and if you set the size of the brush to slightly wider than the bar width of the letters. For example, in this picture I removed the year from the date (in the lower right corner) by using the "retouch" brush and following the contours of the letters. (the screen shot is from iPhoto '11, but iPhoto 9 should give similar results).

How can i find out the resolution and accuracy of PXI-6602 module?

I have a 32 bit 8 channel PXI-6602 counter module. PXI card is interfaced to PC with MXI-4 link. How can i find out the resolution and accuracy of this system.What is the maximum accuracy and resolution i will get from this system. Because optical signal to cmos conversion signal is given as a input to the counter.

Hi chandhu,
Were you referring to the accuracy of the count register or the timing clock?
PXI-6602 specifications can be found in the NI 660x Specifications. The resolution of the count register is, as you’ve noted, 32 bits. This corresponds to a maximum count value of 4,294,967,295. As long as all of the edges are in accordance with TTL specifications, the accuracy of the count register is 100%.
On the other hand, the PXI-6602 baseclock accuracy takes on the baseclock accuracy of the PXI CLK 10 signal. Again, this is all found in the specifications.
You may also want to check out the NI 660x User Manual – it contains a lot of details on the operation of these counter/timer devices.
I hope this helps. Please post back if you have further questions.

How should we be going about creating and saving and/ or exporting our ODC files using Excel 2013 for use in Project Server 2013 Online?

Hi I need your guidance on how I should go about setting up my Excel 2013 reports so that others in our Project Online 2013 environment can access and updates these reports of mine.
My questions are as follows:
I presume I need to create and save my ODC files in a PWA > Data Connections folder. I have English and French users in our environment. Do I need save them twice? Once in the French and again in the English Data Connections folder?
Likewise for the Excel file?
How should I go about creating my ODC files within Excel? By default, the ODC files are being created on my PC's > My Documents > My Data Sources folder. I presume I need to get them saved or exported to the PWA > Data Connections

Thanks in advance,

Thank you Guilaume. May I ask you to help clarify a bit more for me? If I have to do it for both languages (the reports and ODC files), do I simply copy the same ODC files from e.g., the English to French folder in PWA (Odc files)? Or does
that defeat the purpose? Or, do I need to create a new set of oData Feed Connection files with a French version of Excel 2013 and save them to the French Data Connections folder in PWA? Do I need to have a French version of Excel 2013 to create
French ODC files and ultimately French based reports and/ or vice versa?
I did notice that the following oData metadata command from within a browser produces different results (ie., English versus French metadata returned) depending on who runs it (i.e., French or English user, etc). As you can see I am a bit confused.
Any help you can provide would be greatly appreciated.
