The docker-compose for Oracle 12c XE

Oracle Database Express Edition

After a while got time to explore the new learning in my way. Oracle Express edition on docker container is my goal. In this post I am going to explain you how did I achieved this with different path of using docker-compose commands to bringing up the automated XE container. The regular choice is defined in GitHub and Docker hub it was mentioned to use docker pull and docker run commands to use.

Advantages of containerizing Oracle 12c XE

  • No need to download any software from OTN
  • No need to install - dockerfile will take care of it
  • No need to run dbca for Database cration - executed moment container boot time
  • No need to start LISTENER, STARTUP database because this container choosen is AUTOMATED [OK]

Lets search for the Oracle 12c XE

docker search oracle12c

The docker-compose for Oracle 12c XE Database

 image: rodrigozc/oracle12c
  - "1521:1521"
  - "8089:8080"
  - "2222:22"

docker-compose config
networks: {}
    image: rodrigozc/oracle12c
    network_mode: bridge
    - 1521:1521
    - 8089:8080
    - '2222:22'
version: '2.0'
volumes: {}

docker-compose up -d
Creating oraclexe_oracle12cxe_1

Now lets check the docker-compose wit running process list
 docker-compose ps
         Name                Command       State                                  Ports
oraclexe_oracle12cxe_1   /    Up>1521/tcp,>22/tcp,>8080/tcp

SSH Connection with port 2222

Using PuTTY terminal you can connect to the container that is running Oracle 12c XE database in it.

check logs what is happening in the container when it was just started...

vagrant@docking ~/oracle_xe $ docker-compose logs oracle12cxe
Attaching to oraclexe_oracle12cxe_1
oracle12cxe_1  | SSH server started. ;)

oracle12cxe_1  | Look at the log file "/u01/app/oracle/cfgtoollogs/dbca/xe/xe.log" for further details.
oracle12cxe_1  | Configuring Apex console

Here the log file shows that installation successful. And Now lets check the Expression Edition Enterprise manager console

Oracle Enterprise Manager database express 12c Login page
Please enter the the login credentials as: sys/oracle select the check box as sysdba option. Because we want to do a DBA task now create user.

After login successful you will get the SYSDBA access.

Create User on Oracle 12c EM Console
Create User account as demouser 

Tablespaces for demouser

Assign privileges RESOURCE, CONNECT to demouser

Create User SQL statement processed succesfully

In the PuTTY terminal connect with oracle/welcome1 ssh credentials.
export ORACLE_HOME=/u01/app/oracle/product/12.1.0/xe

To check Oracle Database running with process that have pmon word:
 ps -ef|grep pmon
You can check for the Oracle database configured and the Listener started with script.

The command completed successfully

Confirm the User creation

Using SQL*Plus you can test the connection to the demouser that created in the above section.

 sqlplus demouser/welcome1@localhost:1521/""

Output looks like this:

You can also define your own SID and use that for creating RCU and move further.

Please share your feedback on this experiment how it helps you and any suggestions to improve more posts on containerization in Oracle DevOps.

  1. I think I've found a nice informative blog after searching a long time. Thanks for your great articles and information, Its very Helpful for everyone.The contents are quiet interesting. I will be waiting for your next post.

  2. Faced the below issue.
    Table empdemo doesn't need to be dropped.
    Exception was thrown: ORA-01950: no privileges on tablespace 'USERS'

    And resolved by following steps:-
    1.Login to the Em console using sys\oracle. the security>Users>search for USER1, the USER1 in the action column.
    4.USER1> Account Summury> Contains details and select quota tab.
    5.Select USERS>TableSpace>Click on Edit> It pops up Alter Quota window.
    6.Change the value from 0 to 10M.(Make sure it should be capital letter).
    7.Click ok to Alter the tableSpace.
    8.And finally executed the java Program it executed it works.
