Windows7bugs | Script Copying Instructions

Hello guys

Once in a while we receive complaints about scripts copied from our blog causing issues. We regret those issues and apologizing to everyone who suffered due to. Our blog is totally free until date and unfortunately, different browsers behave differently while parsing the code tags.

We were using

 [ code ] [ /code ]

tag for long time, found that few scripts getting totally messed up with double quotes being showsn and &quote etc. This has forced us to start using

[ sourcecode ] [ /sourcecode ] 

and realized if we have more than one block of scripts, the 2nd and consecutive scripts blocks being totally garbled.

With reference to above said, we request you to kindly make sure that the scripts those you copy from our posts are thoroughly checked for special characters prior applied. Especially registry related scripts as such attempts could completely wreck your Windows registry databases.

We hope you read us clearly and continue supporting us.

Regards,

Windows 10 |The device is being used by another application

Hello guys

Greetings! Yes, I know it was a long break. Trust me, I wanted to post many things, couldn’t as I was too busy (doing my actual job, traveling etc ;) )

Anyway, Windows 10 is never packed with less surprises. Recently I was going through a 4K video clip with multilingual audio tracks & realized that the much celebrated VLC player cannot play it, when the default Movie & TV windows app played the clip without a single break or lag. However, as soon as I tried to switch the default language from “Arabic” to “English” I started getting the error “The device is being used by another application” & the app stopped playing the video (lands on the gallery actually)

I was lucky enough to land on a page with correct solution. https://blog.pcrisk.com/windows/12516-how-to-fix-the-device-is-being-used-by-another-application & “Disable Allow Applications To Take Exclusive Control Of This Device Option” section helped me to finally get over with this major annoyance. Not just that, once done, the app remembers the audio track that you selected & plays the same when you open the same video clip next time! unlike VLC player.

If you landed on this page, looking for a solution, please go through the blog from pcrisk.com & they have multiple solutions to this issue and one of the solutions listed there should help you also.

Hope it helps few out there!

Weblogic 12c | Admin Server startup error(s)

Hello guys

Two days back I’ve seen a tweet from Michael Ferrante asking the “Forms Enthusiasts” to hold their breathe, as Oracle is going to announce something “Exciting” for Oracle forms. Are you EXCITED as much I am? Well, I am pretty sure, it is going to be a push for AuraPlayer, as he has mentioned them in the tweet.

Regardless, I’ve a local instance of Weblogic Server 12.2.1.3, installed and a classic domain created. I stopped using it as my firm decided to drop the idea to migrate our 20+ years old Developer 6i developed ERP to Weblogic due to the complexity of Oracle licensing, followed by the uncertainty of Oracle support for Oracle forms beyond 2025 (Which is just 6 years away).

Hell with it, I wanted to see how far I have configured the domain and ended up setting up the forms server, publishing the half baked legacy application. As I have made more than dozen Weblogic installations in last 2-3 years time, I had almost everything backed up from different installations like configuration files, environment and registry files. All I needed was to copy and replace them at most of the places to bring the legacy application online within couple of hours time.

However, I have noticed that while starting the Weblogic Admin Server (from the command prompt, using supplied .cmd files), I was getting a number of java errors & all of them were related to FADS (Forms Application Development Services) & some text were like below (Sorry for the wrapping issues)

weblogic.application.library.LibraryDeploymentException: [J2EE:160141]

Basically, these errors NEVER truly interrupt anything with deploying a forms based application, unless you want to do more with FADS. FADS deployment looks for some specific libraries and missing them were generating the above errors. As I mentioned, for a classic domain, addressing this error may not be truly necessary (for testing). I just love NO errors under usual scenarios, hence decided to fix it.

I referred the below documents to find a proper solution

The 1st document insists that we must delete/rename the pre-installed SQLDEVELOPER (3.x) under ORACLE_HOME (eg: D:\Weblogic\Middleware\Oracle_Home) & install a version that is minimum 4.2, however doesn’t mentioned anything about the highest version supported.

After checking the fads configuration py file, I realized that the files FADS deployment trying to locate during the startup were NOT available with SQLDEVELOPER 18.x:

‘/sqldeveloper/sqldeveloper/lib/oracle.dbtools-common.jar’
‘/sqldeveloper/sqldeveloper/lib/oracle.sqldeveloper.sqlcl.jar’

The 2nd document I referred explained about configuring FADS & the blogger used SQLDEVELOPER 17.2 for his exercise. Hence I downloaded the specific version 17.2, extracted and copied the folder “sqldeveloper” to ORACLE_HOME & followed the instructions as provided within the Oracle document.

Error while using SQLDEVELOPER 18.x

Windows 10 1903 | Oracle VirtualBox virtual machines will not start/open

Hello guys

This is a quick post towards one of the issues I faced once after enabling Windows Sandbox feature that was made available with Windows 10 1903. As Sandbox feature utilizes Hyper-V (regardless whether you have enabled it or not).

Once Sandbox feature enabled, Oracle VirtualBox 6.0.x fails to launch the Virtual Machines.

Although VirtualBox 6.0.x are supposed to support Hyper-V for acceleration, my attempts were futile, forcing me to disable the Sandbox feature, enter BIOS and browse through the virtualization settings.

I can’t say what has resolved the issues. I disabled Sandbox, restarted the box, was unable to launch the Virtual Machines.

Restarted the laptop, entered BIOS and insured that the virtualization was turned on & tried to launch the Virtual Machines and they opened.

So give it a try, if you are stuck with the following error while trying to open a Virtual Machine!

Call to WHvSetupPartition failed: ERROR_SUCCESS (Last=0xc000000d/87) (VERR_NEM_VM_CREATE_FAILED).

Wireless Keyboard/Mouse lags, stutter or hang when USB 3.0 external HDD connected

Hello myself

Recently I replaced my faulty Microsoft Keyboard+Mouse combo with a Logitech K270 & must say, Logitech have some quality.

However, very soon my daughter told me that she cannot use the keyboard & it prints a letter few seconds later after she taps the keyboard. I came to the desk and confirmed that she was right.

I was really upset, I couldn’t believe that a brand like Logitech could make such lousy product which started malfunctioning within couple of hours since the 1st use!

I was copying a huge tar ball from the external USB 3.0 HDD, connected to the port adjacent to wireless receiver was connected. Somehow I managed to close the copying & removed the wireless receiver to check whether it was broken/visibly faulty. Everything looked rock solid. I plugged the receiver back and the keyboard and mouse were working fine once again.

I plugged the USB 3.0 HDD back to the same port near the wireless receiver as I wanted to copy the tar ball. The moment I plugged the external drive, the keyboard and mouse almost stopped functioning!

Yes, after the long story, the solution is, don’t plug the USB 3.0 external drives to the same USB hub where you connect your wireless keyboard+mouse receiver.

That’s a worth note ;) & I hope you are not reading my personal notes!

Windows Subsystem for Linux | Backup & restore

Hello guys

WSL 2 is almost here! and if you are here, reading this post. Please consider reading about WSL 2

During one of the recent chit-chats, few of my contacts were asking me about the “real” business sense behind Linux on Windows. It is simple. Microsoft is:

Going to integrate LINUX so deep within Windows that, in the very near future, one don’t have to run a separate LINUX Server. Simple like that.

After experimenting with KALI Linux WSL, I managed to install Xfce & XRDP on Ubuntu 18.04 WSL & the only few things I couldn’t do with the WSL was starting services automatically when the subsystem starts. There are hacks, well, I don’t think they really worth a try soon as Microsoft will BE bringing it on to WSL pretty soon.

Now, let us get back to the topic. I’ve installed Ubuntu 18.04 WSL nothing less than half dozen times. Every time something goes wrong & I am forced to uninstall and re-install the WSL to continue with additional experiments. My last attempt was to install Kubuntu desktop, that screwed my Xfce & after 2 days of continuous efforts to “fix” few “unknown” things, I had to uninstall one Ubuntu WSL that had a fully functional WordPress instance :(

So, I decided to learn how to backup a functional WSL, so that if something goes wrong, I can restore & continue

I’ve ready at few places that Windows 10 version 1903 comes with WSL backup functionality out of the box. Until you decide to upgrade your box to 1903, you may use the below for backing up your dear WSL instance.

I came across a pretty decent thread here & a user Jaime’s answer is the apt ONE, missing only few details like /tmp folder.

Make a tar ball as mentioned by Jaime

# cd /
# sudo tar vzcpf /mnt/c/tmp/ubuntu_`date +%Y%m%d_%H`.tar.gz --exclude=/proc --exclude=/dev --exclude=/mnt --exclude=/media --exclude=/lost+found  --exclude=/tmp --exclude=/sys  --exclude=/run / > /mnt/c/tmp/ubuntu_`date +%Y%m%d_%H`.log 2> /mnt/c/tmp/ubuntu_`date +%Y%m%d_%H`.error

Where /mnt/c is C:\> drive of your Windows Machine. You may change /mnt/c/ to /mnt/d/ or /mnt/e/, based on how your partitions are laid. Closely watch the excluded directories. You MUST exclude them.

My tar ball was around 1.5GB in size & I moved the tar ball to another machine which didn’t have WSL activated.

First you have to enable Window Subsystem for linux from Turn Windows Features on or off (If you are not restoring the backup to same Windows Machine). This will ask you to restart your Windows Machine.

Copy the tar ball to a folder, say, D:\wsl

Download launcher.exe from https://github.com/yuk7/wsldl

Copy launcher.exe to D:\wsl

If you are going to restore a Ubuntu 18.04 WSL rename launcher.exe to Ubuntu1804.exe & rename your tar ball to rootfs.tar.gz

Open an elevated command prompt & switch to D:\wsl

and just execute, for example “Ubuntu1804.exe”

It will take a while for the installation to complete. As the superuser thread states, it installs and opens the WSL for you. From next time, all you need to do is to start Ubuntu1804.exe & your WSL instance is up and running!

However, I had an issue with the restored instance. It was related to missing /tmp folder. I found a solution for it with nixcraft article.

https://www.cyberciti.biz/faq/mysqld-innodb-error-unable-to-create-temporary-file/

Prior trying to start any sevices, those you were using with your backed up instance, make sure you create the /tmp folder like below

$sudo chown root:root /tmp
$sudo chmod 1777 /tmp

Now, try to start your services, start xrdp & enjoy!

Windows Subsystem for Linux | WSL | Ubuntu 18.04 with Xfce & Xrdp

Hello guys

As many of us know, starting from Windows 10 1803, Microsoft has made Windows subsystem for Linux running in the background even after the console windows are closed.

Definitely this is a gain for those developers who want to have a Linux environment available always, regardless whether the console windows open or not. My requirements towards the same is pretty limited, as I have live Linux systems for almost all my experiments. However, was never less motivated to explore the WSL environments.

Last time I posted a thread about installing and configuring Ubuntu 18.04 WSL and setting up apache, MySQL.

This time we will see how you could enhance your Ubuntu 18.04 WSL with a proper GUI (Desktop environment). I am sure, majority of the Windows users will appreciate a GUI to interact with Linux against the Linux geeks who prefer command line interactions. In addition, few editors like geany or gedit ONLY could be used in a GUI environment.

We will be using Xfce (light weight desktop manager) & XRDP to achieve the GUI requirements on Ubuntu 18.04 WSL

Fire up your Ubuntu 18.04, and update the instance to the latest

sudo apt update && sudo apt upgrade

This could take a while to complete depending upon your internet connection speed

Once the update & upgrade finished, we will install both Xfce & Xrdp in a single session

sudo apt install xfce4 xrdp

The installation should be pretty smooth and within few minutes everything should complete. Not a single attempt from my end failed to install both Xfce or Xrdp

Once the installation is over, we MUST make sure that the XRDP doesn’t use port 3389 which is used by Microsoft RDP (in case if your Windows 10 is already configured for RDP). Hence we will edit the XRDP configuration file with a different port, in our case 3390

sudo vi /etc/xrdp/xrdp.ini

Change the port from 3389 to 3390 & save the file.

Now we will try start the XRDP service

rajesh@rt04:~$ sudo service xrdp start
* Starting Remote Desktop Protocol server [20190509-12:13:49] [DEBUG] Testing if xrdp can listen on 0.0.0.0 port 3390.
[20190509-12:13:49] [DEBUG] Closed socket 6 (AF_INET6 :: port 3390)
[ OK ]
rajesh@rt04:~$

That’s it

Open Remote Desktop Connection from your Windows Machine & log on!

Supply your WSL username and password. You can use ONE of the existing WSL usernames, in case if your WSL have more than one user.

One of the main issues I found using Xfce4 was few goodies like print screen should be installed by the user prior screenshot capturing could be made (I took screenshots from the remote session & copied them to Windows for this post). This will include adding new keyboard shortcut keys.

We’ll quickly see how to resolve the above said

First install missing “xfce4-screenshooter”

sudo apt install xfce4-screenshooter -y

Once the package installation finished, we will define a new keyboard shortcut that binds “Print Screen” physical button on the keyboard to Xfce4 screenshot shooter package.

Launch Applications -> Settings -> Keyboard

and using the “Add” button, Create a new shortcut. Xfce4 supports different switches to be used with screenshooter package. I’m using the “-f”, for full screen captures.

Be careful when you define the keyboard shortcuts. There is a space between the command and switches, for example

xfce4-screenshooter -f

There is a space between xfce4-screenshooter & the switch “-f”. Once after entering the command and pressing OK will ask you to tap the physical keyboard button that you want to bind with the command. Tap “PrtScr” or other button of your choice & that’s all. Your screen capture should work now.

So why one would even need a GUI over WSL. Well, my answer is short. I always dealt with systems those came with GUI. Many business applications could only be installed over a GUI equipped system. Plus, I am not a geek & after hundreds of attempts I cannot deal with a console based editor like VIM. I feel comfortable with geany/gedit than feeling geeky at mind.

Cheers guys, now your WSL have a GUI. Start think about what YOU can’t do with WSL!

Happy developing!

Oracle Application R12 | The Function Is Not Available Under The Responsibility

Hello guys

It looks like I am getting something new everyday to blog…the latest is from Oracle Application R12 once after I added a new responsibilities to few users.

The Functions those are listed under new responsibility from the HTML page will not launch, instead a popup window appears with the statement “The Xyz Function Is Not Available Under The abcd Responsibility”

I recently had a nightmare with a custom form, that was revamped almost after 6 years of usage. Although the compiling on Production instance doesn’t have any issues, only portions of the form would load & the only few elements displayed were totally misaligned and the cells looked like just a plain straight line…

After many failed attempts, I tried to clear the cache, which we didn’t from a long time. The culprit was the cache. After releasing the cache, I recompiled the form & everything was fine.

With the above issue also, our issue was with the cache. After releasing the cache, the users were able to launch the form from the HTML page itself. If, this didn’t resolve your issues, have a look here
