Oracle Multitenant – Administer a Container Database (CDB)

dbi InSite Workshops

In Oracle 21c only the multitenant architecture (CDB) will be supported. I.e. it will no longer be possible to create non-CDBs, which have a status “deprecated” already since 12cR2. At the same time, and starting with version 19c, Oracle allows up to 3 Pluggable Databases (PDB) per CDB in Standard and Enterprise Edition, without paying license fees for the Multitenant option. It therefore becomes essential to train your multitenant skills. Thanks to practical exercises, our training allows you to acquire the essential knowledge to switch to multitenant 12c, 19c or 21c, to adapt the administration tasks and to benefit from the functionalities brought by Pluggable Databases.
