Modify Windows file Change / modified date.

There is no straightforward command in windows to change the file modify date (Commonly referred to as timestamp) . I have spent significant time searching UNIX touch -t like command equivalent in windows but could not find a command that could achieve this feat.

However there is a a way around through a VBS . This VBScript would let you modify the file timestamp (Modified date ) to the one you give in the parameter. In below example it would be 29-Oct-2015.

Sub ChangeModifiedDate(strFolder, strFile, dteNew)
    Dim oShell
    Dim objFolder
    Set oShell = CreateObject("Shell.Application")
    Set oFolder = oShell.NameSpace(strFolder)
    oFolder.Items.Item(strFile).ModifyDate = dteNew
End Sub
changemodifieddate "D:\myfolder\fmx","new_empl.fmx","29-10-2015"

So here are the things to change.
Change the last line 1 st argument is the windows folder.
2nd Argument is the file name
3rd Argument is the Date modified desired. One needs to put this code in text file (or create .vbs file) .

Rename the file extension to .vbs . Double click to execute and you are done !!

Use the Microsoft Visual Studio Code(VScode) with Java Maven project.

The VS Code is the go to editor now a days for the latest technologies and scripting options. VS Code as we all know works seamlessly with Python and JavaScripts, and offcourse the .NET family. But VS Code has many extensions which makes it big Java IDEs run for their money. Lets explore what we could do with VSCode if we are Java developer. Install VScode , no brainer. Jus type download Visual Studio code in google. Alrright once we have VSCode. Open it. Install Maven and Java extension. 2. Go to files and a small window will now appear on left side navigation bar. 3. Select New Maven project. 4. Select the archtype from dropdown. 5. As usual input the grpid, artifactid etc. 6. Done. Go through a video which has much detailed navigation flow. Till next time !!!

Cyclic blocking session removal script written by me for Oracle Database.

Plenty of times we have cyclic database blocking sessions. We have the script which runs in loop and kills them , only to see new blocking sessions have resurfaced. This is a classic scenario that happens many time due to poor application design. A was blocking B , B was blocking C. Unless you have some automated blocking session clearing script. You would run a script at point in time killing session of A. Giving the lock ownership to B. B could realize it late that he has the lock and not commit his work. So DBA again goes in and sees block kills B's session. In meantime Frustrated A logs in and start his activity again queuing him up in wait for lock retrieval . This goes on and you end up running the script 5-10 times to kill these sessions to finally clear the blocks. Note this is not a deadlock which is normally apprehended and identified by oracle. In such case we had written below plsql to clear the sessions. This basically goes in and check for locks ever...

Introduction to Oracle Analytical functions , rank , denserank.

In this video we tried to demonstrate how oracle anaytical function works. How to do Top N query with oracle's rank and dense_rank function. Also explained is how outputs and functionality of rank and dense_rank differs , what should be used when. The demonstration video is from Linux Mint OS and I have used my own Query Light application. Hope you find it enlightening. Here are some of the screen prints. Use of Oracle Rank Analytical Function. Oracle Top N Query using rank analytical functions.
