docker-dataguard

Files for building an Oracle Data Guard database in Docker

Currently working for version 12.2.

Setup

Set Docker's memory limit to at least 8G

Prerequisites

This repo is built on the Oracle Docker repository: https://github.com/oracle/docker-images

Download the following files from Oracle OTN:

LINUX.X64_193000_db_home.zip

Set the environment

The ORADATA_VOLUME is for persisting data for the databases. Each database will inhabit a subdirectory of ORADATA_VOLUME based on the database unique name. DG_DIR is the base directory for this repo.

export COMPOSE_YAML=docker-compose.yml
export DB_VERSION=12.2.0
export IMAGE_NAME=oracle/database:${DB_VERSION}-ee
export ORADATA_VOLUME=~/oradata
export DG_DIR=/root/DataGuard-docker

Run the build to create the oracle/datbase:19.3.0-ee Docker image

./buildDockerImage.sh -v 12.2.0 -e

crate valume dir

make prepare_dir

Run compose (detached)

make docker_up

Tail the logs

docker-compose logs -f

Testing

The build has been tested by starting the databases under docker-compose and running DGMGRL validations and switchover through a variety of scenarios. It correctly resumes the configuration across stops/starts of docker-compose.

Please report any issues to oracle.sean@gmail.com. Thanks!

CUSTOM CONFIGURATION

Database configurations

Customize a configuration file for setting up the contaner hosts using the following format if the existing config_dataguard.lst does not meet your needs. This file is used for automated setup of the environment.

The pluggable database is ${ORACLE_SID}PDB1. The default configuration is:

cat << EOF > $DG_DIR/config_dataguard.lst
# Host | ID | Role    | DG Cfg | SID  | DB_UNQNAME | DG_TARGET | ORACLE_PWD
DG11   | 1  | PRIMARY | DG1    | DG11 | DG11       | DG21      | oracle
DG21   | 2  | STANDBY | DG1    | DG11 | DG21       | DG11      | oracle
EOF
