The following major features are new in this release: In-Memory Column Store (IM column store) dynamic resizing. The IMEU stores these columns in the OSON (binary JSON) format. Still both parameters will be autotunes. 21c |
You can allocate MEMORY_TARGET parameter and oracle will handle both SGA + PGA. The value can be set to "0" or reset if you no longer want to control this parameter. This way you are protecting the PDBs from noisy neighbours by reserving the CPU, but if the system is quiet the PDB is not so restricted, so idle cores/threads don't go to waste. I added links to the parameter but at the time Im writing this, only 2 of the 5 new parameters are documented in the 19c manuials. A join group is a user-created object that lists two columns that can be meaningfully joined. See "Forcing Initial Population of an In-Memory Object".
