I’ve been using Oracle VirtualBox for last many years and ever since I moved to Windows 10, experienced some unexplainable stuttering and lags with Windows 10, 11 virtual machines. I think finally I made a breakthrough for myself. I am not sure whether this approach is helpful for everyone as virtual machines behave differently on different hardware setups. I’ve gone through many VirtualBox forum posts discussing issues with same nature, particularly with NVidia graphic chips/cards & all my boxes have NVidia graphic chips or cards.
My work laptop configuration.
and has one NVMe ssd for the OS and 2TB SSD for data on which I have all my virtual machines. Regardless, with the amount of hardware resources, my Windows 10 virtual machine stuttered, and the experience was horrible, compared to the Windows XP VM that I had. I never had issues with Linux VMs either. I tried almost every trick in the book and always ended with gaining very little.
Couple of weeks back, for one of the Oracle labs exercises I started the Windows 10 VM and for some unknown reasons found the virtual machine was not automatically resizing display. I managed to fix this problem earlier by changing the graphics controller from VBoxSVGA to VBoxVGA, force auto resize & switching graphics controller back to VBoxSVGA. For that exercise I disabled the 3D acceleration, basically landing on a solution unknowingly. I repeated the same exercise and found my Windows 10 virtual machine snappier than ever! To confirm, I switched back to 3D acceleration & managed to reproduce the same choppy, stuttering experience with the same virtual machine once again.
Let us see what happens with we enable 3D acceleration for the graphics controller.
VirtuaBox allows a maximum of 256MB memory for Video & check the below image to see what happens when we enable 3D acceleration.
half of the video memory is consumed by the 3D acceleration! OS like Windows 10, 11 have pretty heavy graphic elements and obviously the limited video memory makes the OS stuttering and lagging whole the way (or this is what I assume from my experiments).
As I mentioned in the beginning, disabling the 3D acceleration works for me on three different machines & different Windows OS virtual machines. Hope this helps few others out there.
I have one Windows 10 guest from last many years, upgraded through VirtualBox versions 5, 6. Recently I upgraded VirtualBox to 7. While Windows XP & Oracle Linux guests automatically resized the display on host, Windows 10 guest was adamant. Uninstalling and installing the guest addons didn’t help.
After scavenging through few posts over VirtualBox forums, came across one of them discussing about fixing the resizing issue by choosing “VBoxVGA”, though it was not supported. I decided to give it a try and Windows 10 guest resized the display when I toggled the “Auto-Resize Guest Display” from the view menu.
Then I shutdown the guest, changed the Display back to “VBoxSVGA” & the guest allowed me to resize the display using View menu & subsequent restarts were resizing the guest display as expected. However, there were times when I had to manually adjust the display size. Hope Oracle fixes this issue in coming releases.
Last couple of years, I stopped evaluating new Windows OS, as they were shipped with so many bugs and updates breaking them further. I felt reporting the bugs didn’t make anything better & few of the folks from Microsoft on Twitter are just lame like their OS. Always finding excuses for a broken OS.
Well, regardless, I always applied the updates, always fixed the issues and continued working on my projects, which are Oracle development (mostly). Like usual, I’ve downloaded the Windows11 22H2 the very first day it was released and upgraded my work laptop. Basically the OS is once again filled with many bugs, one of the notorious being the large file copying lag issues, that is openly acknowledged by Microsoft.
Well I was stuck by an undocumented issue ;) Whenever I tried to open File Explorer, it took many minutes before it was ready to interact with. None of the searches landed me on a proper solution & I just wasted hours tweaking the OS following tips to parameterize the OS for better performance. Then I was expected to copy a large SQL output for our sales manager and I had a shortcut for a folder in his computer on my desktop. I couldn’t open this folder this time & I couldn’t find his laptop’s hostname in the DNS. As the folder was mapped using the hostname, every time I tried to access the folder, gave me the same network path not found error. It took the same amount of time file explorer tried to open & I could make a guess towards what was going wrong with the file explorer.
I remembered this particular folder always listed under the quick access area of the File explorer & I removed it from the quick access area once after the File Explorer was ready next time. File Explorer started opening as snappier as possible then onwards.
Now, this looks like another problem from Microsoft’s latest release that attempts to connect to all the items listed under quick access, ie, like connecting the network folders & failing to establish a connection, throws the exception “File explorer not responding” and taking minutes until the attempts are aborted.
I’ve many folders pinned to quick access area, as a developer I work with multiple projects and this saves loads of time for me. Windows 10, 11 keep tabs on regularly accessed items and pin them to quick access area, a default behavior of the OS. This might create certain unexpected situations like the one I described above. I will not say this feature is useless, but sometimes a user who is not that tech savvy may never realize what is going on here. If I were the File explorer designer/developer I will definitely make sure to code the piece in a way that Explorer would try to connect to network folders only when the user tries to open the folder.
Said, if you are having the same issues with File Explorer taking too much time to open, please check whether any network folders are listed under Quick Access area. If yes, remove them. Unless you are a die hard of fan of automatically pinning items in the Quick Access area, disable the automatic pinning.
This could OS automatically pinning items to your Quick access area & avoid the issue I were discussing.
If your hardware is eligible, might have noticed a banner like below
whenever you visited Windows update settings area. It’s free, it’s ready & there are a million possibilities stop your computer from upgrading to Windows 11. The only one thing Windows upgrade manages to show is a popup telling you “Windows 11 installation has failed” after a failure.
Please note, as I already mentioned, there could be a million reasons failing the upgrade, especially when you are upgrading from Windows 10 that was upgraded from different versions of Windows 7,8 and 10 itself. I’ve lost of the count of upgrades I’ve made to my semi-server type desktop machine and didn’t expect Windows 11 upgrade all smooth at the first place. I knew I was in for a long game. My machine has different database software installed for testing, my Kids have heavy games like Doom & other and a clean installation was not at all my first choice.
So my first task was to find out where exactly the installation process writes the errors. To be quite frank, I haven’t had many installation/upgrade issues in near future and I totally forgot where to look for the logs! A quick search landed me on this post Log files that are created when you upgrade to a new version of Windows (microsoft.com) & as my upgrade failed, I was able to locate the “setuperr.log” file at this location “C:\$Windows.~BT\Sources\panther”
Based on the errors, the log file could have hundreds of lines. Mine had the below listed.

Among of a list of issues, I recognized the duplicate profile error(s) without much sweat as this issue has been persistent from the Windows 7 times.
Now the fix that is discussed here is not for a normal computer user. If you have landed here, searching for a solution for your home computer and haven’t dealt with Windows registry in the past, manually managing it, please stop & seek the help of someone who is familiar with these kind of activities.
Make a backup for complete Windows Registry. This is very important to rollback incase if something goes wrong.
Go to “Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList” node. From the setuperr.log file you already have a profile id that is reported as “duplicate”. Browse through the profile ids and locate the profile that doesn’t exist. For example, my user account for the system is “rajesh” and I had two profile ids, one having the Profile Image Path “C:\Users\rajesh” and the other profile id having profile image path “C:\Users\Rajesh”
I deleted that non-existing profile id from the registry (ie, C:\Users\Rajesh) and restarted upgrade. Everything went ahead smooth and within next 10-15 minutes, Windows 11 booted without issues.
A list of other measures that you could try in case if your upgrade fails are:
Remove all connected external devices other than keyboard & mouse
Uninstall SSD/NVMe managers (software that help you to monitor the SSD drives)
Uninstall 3rd party antivirus software. One of the major reasons for failures
Check for adequate free storage space on your system drive, normally C: drive
Use Windows built-in troubleshoot to fix Windows update errors
During installation, let the installer check for updates and download the necessary
We’ve our Oracle EBS instance hosted from Linux environment. However I post much for the Windows OS as I see there are not many articles targeting Oracle on Windows. I think for better view counts, I should consider posting the articles for both OS.
In my last post about restoring 1g RMAN online backup to 19c non CDB database, I said my ultimate goal was to convert the upgraded database from non CDB to PDB, that is plugged on to an existing CDB. Let us see how to achieve this goal this time.
Before start, there are few mandatory checks you must do to insure a successful migration from Non CDB to PDB. I will list few of them those came as hurdles for me.
Character Set. Make sure that your CDB and the Non CDB database have the same character set. There are few possible conversions. Please check 12c Multitenant Container Databases (CDB) and Pluggable Databases (PDB) Character set restrictions / ORA-65116/65119: incompatible database/national character set ( Character set mismatch: PDB character set CDB character set ) (Doc ID 1968706.1) for more details. My CDB was using Arabic character set and the upgraded non CDB database was using a noncompatible set. So I dropped the CDB and created a new CDB without PDB(s). Dropping a CDB will not be always possible because other PDBs are attached to it.
Available storage space. This could be a real concern incase if you are planning to create a PDB, cross verify & then delete the non CDB database. You will need approximately the same size of your non CDB datafiles size storage available to do this activity. My database was less than 5 GB in size, hence it never occurred to me. If your database has a bigger size, plan accordingly.
Let’s do it now.
From and elevated command prompt (Windows Terminal is not yet matured enough to handle such “heavy” tasks) source the non CDB. Shutdown and startup mount exclusive.
C:\Windows\system32>set ORACLE_SID=KAZEMA
C:\Windows\system32>sqlplus / as sysdba
SQL> shu immediate
SQL> startup mount exclusive
SQL> alter database open read only;
Create manifest file for the non CDB now.
SQL> exec dbms_pdb.describe (pdb_descr_file=>'D:\Oracle19c\kazema_manifest_file.xml');
SQL> shu immediate
Source the CDB now.
C:\Windows\system32>set ORACLE_SID=KAZEMACDB
C:\Windows\system32>sqlplus / as sysdba
SQL> SHOW CON_NAME
CON_NAME
------------------------------
CDB$ROOT
Now, we need to see whether non CDB meets the compatibility requirements. There could be multiple elements those you may have to fix before, the non CDB is ready for a successful migration as PDB. You will have to refer PDB_PLUG_IN_VIOLATIONS view for these details. Go ahead, execute the below code block.
SQL> SET SERVEROUTPUT ON;
SQL> DECLARE
Compatible CONSTANT VARCHAR2(3) :=CASE DBMS_PDB.CHECK_PLUG_COMPATIBILITY
(pdb_descr_file => 'D:\Oracle19c\kazema_manifest_file.xml')
WHEN TRUE THEN 'YES'
ELSE 'NO'
END;
BEGIN
DBMS_OUTPUT.PUT_LINE(compatible);
END;
/
YES
My case I didn’t have incompatibilities blocking possible migration. Your case could be different. If the output is “NO”, run the following query (use SQL Developer for better view)
select * from PDB_PLUG_IN_VIOLATIONS where name='<your non CDB name>';
Fix each and every other ERROR & you can safely ignore the “WARNINGS” for now.
Proceed with creating a new PDB from the manifest file that we have created in the 1st step.
SQL> CREATE PLUGGABLE DATABASE KAZEMA USING 'D:\Oracle19c\kazema_manifest_file.xml' COPY FILE_NAME_CONVERT=('D:\ORACLE19C\DB\ORADATA\KAZEMA\DATAFILE','D:\ORACLE19C\DB\ORADATA\KAZEMA');
Pluggable database created.
SQL> show pdbs;
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
2 PDB$SEED READ ONLY NO
3 KAZEMA MOUNTED
Once the PDB has been created, confirm the same & proceed with balance activities. Run “noncdb_to_pdb.sql”
SQL> alter session set container=KAZEMA;
Session altered.
SQL> @$ORACLE_HOME/rdbms/admin/noncdb_to_pdb.sql
Based on the resource available, this might take a while for the script to complete execution. Once completed you can try to open the PDB. Check for Errors and Warnings in the PDB_PLUG_IN_VIOLATIONS view. If there are new ERRORS & WARNINGS fix them.
A typical scenario could list you many things like this (reference image only)
After fix attempts, I am still left with one Warning about sys lock issues. This is mainly due to the password file format 12.2. I hope to find a solution soon for it. Status column states whether the Error/Warning was taken care off.
SQL> alter pluggable database open;
Pluggable database altered.
SQL> SELECT name, open_mode FROM v$pdbs;
NAME
--------------------------------------------------------------------------------
OPEN_MODE
----------
KAZEMA
READ WRITE
1 row selected.
SQL> show pdbs;
CON_ID CON_NAME OPEN MODE RESTRICTED
---------- ------------------------------ ---------- ----------
3 KAZEMA READ WRITE NO
SQL>
Now you have a non CDB and PDB with the same SID. You can proceed with dropping the non CDB database after cross verifying the concerns.
Foot Note: If you are plugging a database that was hosted in another server/computer after converting, make sure to verify the “local_listener” parameter for the PDB exist.

If the local listener is not reachable, PDB level services will fail to register with listener and the applications those depend on such services will fail to establish connections. This applies mostly to Oracle E-Business Suite environments and could be mapped to sophisticated applications that use specific service names to establish connections to the database.
KB5009543 or Cumulative update Jan 2022 for Windows 10 and Windows 11 is currently breaking IKEv2 VPN connections. If you are experiencing an unexpected connection failure with a vague error message like “General processing error”, please follow the below steps.
Go to Program and Features -> Installed Updates and uninstall KB5009543. Reboot the box and the VPN connection should start working normally. Optionally you may disable the Windows Update for a period of time so that the same update will not get installed once again. Please note, Microsoft releases updates to their products quite often to resolve issues those were identified. Few times these updates open new issues, like the one happened with this particular KB.
While there are no straight forward methods available to “stop” Windows updates, you can use multiple methods to disable Windows update completely, which we don’t recommend. One of them is using group policies on the local machine.
If you still consider disabling Windows updates temporarily/long term, please refer this excellent tutorial
We migrated to 11G R2 (11.2.0.4) for our Oracle Applications R12 few years back, yes few years back (2017) & lived with one of the worst experiences…
Connecting Oracle Developer 10g (Forms/Reports) suite to 11G database.
I have scavenged through community articles for long time before giving up. I hardly came across a single fix for the connection time that used to hang up the Developer suite at times…
Today, I decided to find a solution for the nagging SSH connection issues from Windows 11 to our LINUX application servers and realized that we didn’t update the DNS settings for them once after we decommissioned a domain controller. Once the SSH issues were rectified and addressed, my next attempt was to find a solution for “frmcmp_batch” taking long time to start compiling modules & I landed on the below post.
As we are already on 11G R2 11.2.0.4, patching was not required. All I needed was to alter the hidden parameter “_FIX_CONTROL” as mentioned in the article.
SQL> ALTER SYSTEM SET "_FIX_CONTROL"='8560951:ON';
(Use scope=spfile to make this change permanent. This will require you to restart the database.)
I opted to go without spfile for testing & as soon as applied, the “frmcmp_batch” started compiling the modules instantly, against the usual delay that ran into many minutes other times.
Out of curiosity, I tried to connect to the database from Developer 10g & the connection was instant! within a fraction of a second.
So DNS being one of the most important elements establishing successful connections, patches and fixes also play crucial role in providing stable connections. Were you stuck with the same issue? give the solution a try and let us know whether it helped you also.
Today I re-installed Windows 11 on my computer. Actually I had upgraded from Windows 10 to Windows 11 on October 5th, 2021 the same day Microsoft released the half baked OS to public & all of a sudden I realized that, it was a blunder. So, after regretting over a month, I decided to re-install the OS and started installing all my development tools & you know what, I had to refer my Windows 7 post for installing Oracle Developer Suite 10g on my Windows 11!
Much of the post below is from the earliest post that I had for Windows 7, explaining hacks to install Oracle Database 10g and the Suite. Oracle Database 10g is not anymore significant, hence I removed the database part and posting the rest for few unfortunate Oracle developers out there. Well, 10g is used by many business application as on date & if you are looking for a method to install Oracle Database 10g on Windows 11, Please search the blog for Database 10g and you will land on multiple posts explaining to how (Refer Windows 10 articles)
Step 1 Setup Virtual Memory
If your computer has 8GB or more physical memory, all you need is to setup the Virtual Memory for the name sake. Limit the virtual memory to 2048 (2G) or max 4096 (4G). Please use the below images only for reference purposes. After changing the Virtual Memory, You will be asked to restart the computer and please restart.
Step 2 Setting up the Developer Suite
Depending upon the media that you are using for the installation, Oracle Developer 10g has 2 discs & I have copied the content from both disks inside a folder on my computer. (As you could see in the image above)
Open the Disk 1 folder and locate “Setup.exe’, right click and change the compatibility to Windows XP Service Pack 2 or 3 (doesn’t make any difference)
That’s all. Right click and run “setup.exe” as Administrator. If you have a JAVA installation already on the computer, you might receive a warning message for missing entry point, that you can safely ignore.
Follow the same compatibility setting for patch sets, if you have any. Let me know about your experience through comments.
There are situations, especially while using Windows 10 gen OS (Windows 2016+ Servers included) a user might not able to type inside
Windows Search Textbox
WIFI Password Textbox
For some strange reasons, typing inside these text boxes are supported by “CTF Loader”(C:\Windows\System32\ctfmon.exe)” & that is loaded into computer’s memory normally after a restart/reboot.
This is facilitated by one of the Windows Tasks & certain attempts like using KMSPICO tool to activate Microsoft software, which is ILLEGAL and many times breaks this Task.
So, how do we fix it? There are two different approaches
Rebuild the Task
Using Registry
We’ll see both methods in detail now.
1# Rebuild the Task
If the KMSpico tool or other reason corrupts the Task, you will not find any entries in the folder “TextServicesFramework”
Edited image for demo.
when an intact task should look like below
So how do we recreate this task, that is a custom handler?
Browse to “C:\WINDOWS\System32\Tasks\Microsoft\Windows\TextServicesFramework” & check whether you can find a file “MsCtfMonitor” inside the folder. If you cannot find the file in this folder, copy the file from another Windows machine that has the same version.
Copy the file to desktop and add the extension “.xml” to it.
Opening the file with notepad or another text editor should look like the following:
Go back to Task Scheduler and right click on “TextServiceFramework” and select “Import Task”
Point to the xml file that you have created in the desktop & apply. This should create a new task under the folder “TextServiceFramework”
Restart and confirm you can type in the search box and WIFI password text boxes. Alternatively you can use the Task Manager to check whether “CTF Loader” has been loaded.
2# Registry
Remember, registry entries might get removed through updates/new versions. However, as a temporary measure you can use the following hack to address the keyboard issues.
Make a full backup for the Registry. You must know, tampering registry could force you to a fresh installation of the OS!
Once a full backup for the Registry is made, browse to “Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run”
Create a new string key and call it anything that you want. Example
I have called the string key as “CTFLoader” and for the Value make sure to enter “ctfmon”=”CTFMON.EXE”
Reboot the computer and check whether the typing issues resolved. Alternatively use Task Manager to check whether CTF Loader has been loaded.
Although both fix the typing issues, the right way is to recreate the missing Task. Choose wisely & don’t pirate! We know many interesting software are pricely and many of us cannot afford them. There are free alternatives for maximum pirated software like
And many more software that you need for Office/School/Home works! Piracy not only breaks the businesses that develop them, helps cyber criminals to unleash attacks like Ransomware through serial number generators and patches.
There are times when you come across the error “Windows cannot connect to the printer” (error 0x000003e3) while trying to connect to a “shared“ printer that is connected to another Windows 10 computer.
Quite possible that the drivers installed on the source machine is either not compatible with the client/target machine or not getting copied to the target machine. Now, install the correct version of printer driver to the target machine and try to connect again. There could be few other items you must check and insure for a successful connection.
Make sure both the computers network property shows the connection as either domain or private.
Make sure you have File & Printer sharing enabled for the network
