Get Oracle Version details

In this small post, I am sharing the commands to get details about the oracle version you are using. Although much detail is there in Oracle documentation, but thought of sharing this small tips :).

Steps:

Connect to Oracle DB using CLI or UI tool as you wish. Here I am connecting with Oracel SQL Developer. There are number of ways for getting the details. I sharing below ones.

  1. select * from v$version;


  1.    2. select version from v$instance;

  2.             3. select * from product_component_version;*

  3. Regarding the release number format, there is very good explanation on Oracle Doc site. Please go through it for details.
  4. Thanks!!

boot2docker Error

I have installed boot2docker and when I tried to play with docker, I have started getting below error for every docker commands that I run.

Error

FATA[0000] Get http:///var/run/docker.sock/v1.18/version: dial unix /var/run/docker.sock: An address incompatible with the requested protocol was used.. Are you trying to connect to a TLS-enabled daemon without TLS?



I have checked about the vm status and everything seems good, as below:


After some troubleshooting, I found that issue was with some system variables. Basically there are three variables, which you need to set to make this working. In windows you can use set command and in Linux you can use export command:

   set DOCKER_HOST=tcp://192.168.59.103:2376    
   set DOCKER_CERT_PATH=C:\Users\kuldeep.d.sharma\.boot2docker\certs\boot2docker-vm   
   set DOCKER_TLS_VERIFY=1

Note: When you initialize your boot2docker, it will provide you all details and ask to update variables. 
P.S.- Change above values accordingly :).

Below is the screen shot, where I tried to set each variable and saw the different result and dependencies of these variables on each other.




Thanks!!
