After 7 weeks of constant travelling, I thought it would be good idea to backup my data.
Where to find unneeded backup copies?
JDeveloper and the embedded OC4J use a number of directories to put temporary files to.- OC4J: Your OSs temporary directory. Contents in this directory can be deleted once your applications aren't running. But be aware that some OSs put valuable information there. During deployment OC4J puts WAR and EAR files there. It is same safe to delete them after a deployment.
- JDeveloper: $JDEV_HOME/jdev/extensions and $JDEV_HOME/jdev/system. During Check for Updates JDeveloper creates a backup copy of the previous version of the JAR file containing the Addin in the extension directory. It also creates a new Addin-related directory in the system directory. Once your new and updated Addin works as expected you're free to delete the backups. Be aware that all files with the .jar suffix should remain in the extension directory.
