Check that the system is property configured ‘in particular the ‘Data loop file’ and ‘Base Devise Size’ parameters.
docker info
Connected with oracle,download the docker build images on /u01, unzip the file, then download the 12.2 standard edition installation media into the 12.2 directory
cd /u01 wget https://github.com/oracle/docker-images/archive/master.zip unzip master.zip cd /u01/docker-images-master/OracleDatabase/dockerfiles/12.2.0.1 wget http://download.oracle.com/otn/linux/oracle12c/122010/linuxx64_12201_database.zip
Create the Oracle database docker image for 12.2
Build the docker image for the standard edition (this is the -s)
cd /u01/docker-images-master/OracleDatabase/dockerfiles sudo ./buildDockerImage.sh -v 12.2.0.1 -s . . . Oracle Database Docker Image for 'se2' version 12.2.0.1 is ready to be extended: --> oracle/database:12.2.0.1-se2 Build completed in 2186 seconds.
Create the containers
Create the first database container. Note that the password get generated automatically. Take a note of the displayed passwords:
sudo docker run -p 1531:1521 --name db01 -e oracle_pdb=pdb01 oracle/database:12.2.0.1-se2 ORACLE AUTO GENERATED PASSWORD FOR SYS, SYSTEM AND PDBAMIN: /N1H6CgQZV70=1 ... ...
Create a second database container for process validation purpose:
sudo docker run -p 1532:1521 --name db01 -e oracle_pdb=pdb02 oracle/database:12.2.0.1-se2 ORACLE AUTO GENERATED PASSWORD FOR SYS, SYSTEM AND PDBAMIN: /N1H6CgQZV70=1 ... ...
Change the password to respectively welcome1 and welcome2
sudo docker exec db01 ./setPassword.sh welcome1
sudo docker exec db02 ./setPassword.sh welcome2
