In one of the previous articles I superficially mentioned a relevant limitation in the combination of Multitenant + Dataguard in 19c: It simply cannot execute a synchronized hot cloning (primary cloning cascading to the standby). Today we are going to address that issue in detail, and we will discover an important improvement that we find…

One of the fundamental milestones achieved by the Oracle Multitenant architecture (CDBs and PDBs) is the ability to online rebalance resources between databases; CPU, memory, and even IO (throughput or IOPS). For example, with multitenant, we can immediately rebalance free memory from one PDB to another; something that is currently impossible to do between two…
