This repository contains tutorials for OpenLogReplicator.

All tutorials are based on Docker containers and created and tested on a Debian-based Linux distribution.

Due to differences in Docker installation on different operating systems, the scripts require sudo privileges for creating folders and changing file and folder attributes.

The following folder names are used:

• oradata - Oracle database files
• fra - Oracle database files
• sql - SQL scripts used for tests
• checkpoint - OpenLogReplicator checkpoint files
• log - OpenLogReplicator log files
• scripts - OpenLogReplicator configuration scripts
• setup - SQL scripts used to setup the database
• kafka - Kafka data files
• oracle_libs - Oracle JDBC libraries
• instantclient_23_26 - Oracle Instant Client libraries

The following custom Docker images are required to run tutorials:

• oracle/database:21.3.0-xe - Oracle Database 21.3 XE
• bersler/openlogreplicator:tutorial - OpenLogReplicator

Before running the tutorials, create the necessary Docker images. Not all images are required for all tutorials. Refer to the particular tutorial for the list of required images.
