Tip

Ephemeral Packaging for Oracle Databases

For Oracle databases, two new backup restore methods are available that allow teams to create a temporary, or ephemeral, Ref DB for packaging changes. The functionality uses Oracle’s multi-tenant technology and requires the first database in the pipeline to be a pluggable database (PDB). A copy is created of this database during the packaging operation. Scripts eligible for packaging are applied to the copied database and the copy is destroyed at the end of the packaging operation. There are options to create the ephemeral database in the same CDB container as the first database in the pipeline using the BackupRestoreOracleEphemeralInternalPdb backup restore method or to create the copy in a second, or external CDB container using the BackupRestoreOracleEphemeralExternalPdb backup restore method.

Info

If you have manually changed the java version used by DMC, you will need to restore DMC’s default version of Java (11.0.8) before any time that you upgrade DMC. Move or copy Java 11.0.8 from the /opt/datical/old_jre directory back to the /opt/datical/jre directory prior to starting your DMC upgrade. DMC expects Java version 11.0.8 to be in the /opt/datical/jre directory for the DMC upgrade process to be successful. After your DMC upgrade is complete, you can change to a different 11.x java version again. For more information, see How to Change the Java version for DMC. This link is especially important if you are using v7.18 or later.
