Oracle has recently announced the release of Oracle E-Business Suite 19c Database. With the Oracle Database 19c certification, Oracle EBS 12.2 On-Premises databases are now certified with the CDB architecture (multitenant architecture).
Background
With the launch of database 12c in 2013, Oracle introduced a new architectural concept, called “Multitenant Databases”, where you have one super database (=container; CDB) and one or more sub-databases (= pluggable; PDB).
Note: Read our blog to know more about Multi-Tenant Architecture.
EBS (R12.2) Architecture Overview
This Architecture mainly consists of:
- Application Tier
- Database Tier
- Client Tier

What’s New For EBS With Oracle Database 19c
There are several mandatory architecture updates when you upgrade your Oracle EBS database to Oracle Database 19c. The following is a summary of the key required architectural changes:
- Container Database (CDB) Architecture: With the Database 19c certification, EBS 12.2 on-premises databases are now certified with the CDB architecture (multitenant architecture). As part of the upgrade to Database 19c, you will convert your EBS database to the CDB architecture with a single pluggable database (PDB).
- PL/SQL File Input/Output Directories: With Database 19c, the UTL_FILE_DIR database initialization parameter has been desupported. As part of the upgrade to Database 19c, you must migrate all UTL_FILE_DIR database initialization parameters to database directory objects. EBS development has created a utility to migrate and manage your defined PL/SQL file input/output directories.
- ADG DML Redirection: Previously, you could only update the Global Temp Tables on Active Data Guard standby database. From Oracle 19c, you can also update regular tables.
ADG_REDIRECT_DML enables DML redirection from Oracle Active Data Guard.
