screen command in ubuntu

-
Sometimes you find yourself in a situation where your Network connection is not consistent or you have to execute a time consuming task but do not have all the time to be available in front of your desk, like your shift is going to be over. In situation of these kinds you can use the screen command. With screen, you can reconnect to that server and pick up where you left off with your last command. Screen is a full-screen window manager that multiplexes a physical terminal between several processes. When you call the screen command, it creates a single window where you can work as normal. You can open as many screens as you need, switch between them, detach them, list them, and reconnect to them.

Introduction

Screen is a console application that allows you to use multiple terminal sessions within one window. The program operates within a shell session and acts as a container and manager for other terminal sessions, similar to how a window manager manages windows.

Check version

screen --version

Installation

sudo apt-get update
sudo apt-get install screen

Start screen session

screen -S <session_name>

List available screen sessions

screen -lsr

Detaching screen session

Press ctrl + ad (Press control key and then a and d key [initials] in succession.)

Re-attach screen session

  1. List available screens with screen -lsr
  2. screen -xr <put_session_name_here>

Terminate screen session

  1. List available screens with screen -lsr  [To Reattach screen]
  2. screen -xr <put_session_name_here>[Reattach screen]
  3. Type exit and press enter.

error 18 at 0 depth lookup: self signed certificate

-
I was trying to test SSL connection between MySQL client and server. For that I created SSL certificate and keys by following the MySQL documentation at: Creating SSL Certificates and Keys Using openssl After finishing up all the commands when I verify the certificates by using: openssl verify -CAfile ca.pem server-cert.pem client-cert.pem I got the following output: error 18 at 0 depth lookup : self signed certificate error server-cert.pem: verification failed client-cert.pem: OK  Reason : The Common Name value used for the server and client certificates/keys must each differ from the Common Name value used for the CA certificate. Otherwise, the certificate and key files will not work for servers compiled using OpenSSL. Solution : When OpenSSL prompts you for the Common Name for each certificate, use different names. Common Name (e.g. server FQDN or YOUR name) []: I used values as follows: CA Cert:  ssl-ca-cert Server Cert: ssl-ca-server-cert Client Cert:  ssl-c

How to check fragmentation in MySQL tables

-
MySQL tables, including MyISAM and InnoDB, two of the most common types, experience fragmentation as data is inserted, updated and deleted randomly. Fragmentation can leave large holes in your table, blocks which must be read when scanning the table. Optimizing your table can therefore make full table scans and range scans more efficient. We will mention how to check fragmentation in MySQL tables using SQL queries. USE < put_your_dbname_here > SELECT TABLE_NAME, CONCAT(ROUND(( data_length + index_length ) / ( 1024 * 1024 ), 2), 'M') TOTAL_SIZE, CONCAT(ROUND(( DATA_FREE ) / ( 1024 * 1024 ), 2), 'M') DATA_FREE FROM information_schema.TABLES where table_schema = database() and ROUND(( DATA_FREE ) / ( 1024 * 1024 ), 2) > 0.00 ORDER BY DATA_FREE DESC; SELECT TABLE_NAME, ROUND(((Data_length - (TABLE_ROWS * Avg_row_length))/Data_length) * 100, 2) FRAG_Percent FROM information_schema.TABLES where table_schema = database() and TABLE_ROWS > 0

How to Drop or Remove or Decommission a Database in Oracle

How to Drop or Remove or Decommission a Database in Oracle Database Decommission steps for Oracle 10G and 11g databases Note: ~~~~~~~~ Every organization has its own documented way of removing or decommissioning the active/running database that is supporting an Enterprise’s Application. Here I am presenting some general steps which may coincide with your organization’s standard operation procedure (SOP). 1)   Please get the required approval from Business/Customer to proceed for database decommissioning. 2)   Send the Notification to Business/Customer that we are going to decommission the database. (if required) 3)   Raise a Request for Storage and Backup team to take the required backup (provide all the details in the raised request) and to keep the Backup for a specified period of time, say for next 2 years, (That is called the backup retention period). Retention Period may be varied based on your business needs and SLA. The backup can be on disk or
