You know when you are waiting for the 39 bus for ages, and then two of them turn up at the same time. It’s a bit like this with Oracle 21c XE Database Docker image being released a few days after the 18XE Docker image!
Again we have Gerald Venzi to thank for putting these together and making them available.
If you want to install Oracle 21c XE yourself then go to the download page and within a few minutes you are ready to go. Remember 21c XE is a fully featured version of their main Enterprise Database, with a few limitations, basically on size of deployment. You’d be surprised how many organisations who’s data would easily fit within these limitations/restrictions. The resource limits of Oracle Database 21 XE include:
- 2 CPU threads
- 2 GB of RAM
- 12GB of user data (Compression is included so you can store way way more than 12G)
- 3 pluggable Databases
Remember the 39 bus scenario I mentioned above. A couple of weeks ago the Oracle 18c XE Docker image was released. This is a full installation of the database and all you need to do is to download it and run it. Nothing else is required. Check out my previous post on this.
To download, install and run Oracle 21c XE Docker image, just run the following commands.
docker pull gvenzl/oracle-xe:21-full docker run -d -p 1521:1521 -e ORACLE_PASSWORD=SysPassword1 -v oracle-volume:/opt/oracle/XE21CFULL/oradata gvenzl/oracle-xe:21-full docker rename da37a77bb436 21cFull sqlplus system/SysPassword1@//localhost/XEPDB1
Then to stop the image from running and to restart it, just run the following
docker stop 21cFull docker start 21cFull
