Extend Ubuntu VM hard disk space/size

 Hi all,

Today I will explain about the process to extend and existing disk space in Ubuntu VM.

Environment

1. VMWare
2. Ubuntu

Context

Increase hard disk space more than initially configured for the Ubuntu VM.

Reason

VM hard disk might running out of space.

Procedure

• Make sure we have shutdown the Ubuntu VM
• Increase the hard disk size
• Make sure it's in the allowed range
• 
• Start the VM
• Open the Disks application in Ubuntu
• 
• In below example we are extending it by additional 3GB
• Select the Extended Partition block
• Click Settings (Gear) icon
• Choose Resize option
• 
• Use the increment (+) icon or scroll bar to increase the partition size
• Click on Resize button
• Enter credentials when prompted
• By now, the extended partition will be increased
• Time to select the file system, where exactly our data is getting stored
• We will repeat the process of resizing like earlier
• Using scrollbar increase the disk size
• 
• Click on the Resize button
• 
• The harddisk size is been reflected.

Hurray !! You have increased your hard disk size to store more data on the Ubuntu VM.

The same process can be used for normal Ubuntu OS also.

PL/SQL Developer Useful Settings

Hi friends,

I am using Pl/Sql Developer IDE to connect different databases and performing different database operations at the same time. Its been proved that Pl/Sql developer is very useful tool for sql and/or plsql statement/query execution.

What I liked in Pl/Sql Developer are

1. Select some part of the query and execute the selected part in the query. I liked it very much.
2. Export output result to excel as a table
3. Code assistant which will display all the tables in that schema when you entered your_schema_name.
4. Working in different windows like SQL window, Test window, Program window, Command window and Diagram window at the same time
5. Macros which can do certain action once recorded

What I have learn today is

i) Logon History

Are you able to remember all the username and passwords of different databases?
Fed up of typing username and password everytime when logging?


Use "Fixed Users" option in Logon History Preferences

We can create different menus to differentiate users or type of logons

Syntax:
>Menu
username/password@database

Example:
>Test
abc/abc123@xyz
def/def234@psr

Note: 

• More than one users under the same menu should be in next line

• Avoid @ usage in password because database delimeter is @ so it will treat first @ onwards as database

Example: ghi/lkj@123@qwe
Here

username: ghi

password: lkj@123

database: qwe

but
pl/sql developer will treat

username: ghi

password: lkj

database: 123@qwe

Because first @ onwards it will treat as database.
We can have many menus with many logon to connect different databases with very less effort.
Click the Logon Button Arrow and select the menu->username/password@database
It will get connected automatically without typing username and password

Very Useful .. Try it

ii) Auto Replace facility

Open Pl/Sql Developer->Click on Tools->Preferences->Select Editor Preferences

Scroll down to AutoReplace tab and use the syntax and example to use the facility

syntax: shortcutword=full(part)command

example: saf = select * from 

When you type saf and space then you can see select * from as a replacement of saf
