video is a quick look at online datafile moves in container databases (CDBs) and pluggable databases (PDBs). VIDEO
If you’ve used this functionality in a non-CDB database, it’s going to look familiar, with a PDB-specific gotcha.
These articles discus moving and renaming files.
I’ve added this to my
Multitenant YouTube playlist.
The star of today’s video is
Todd Trichler, but he’s having the share the limelight with the top of Roel Hartman‘s head, and brief clips of John King and Debra Lilley on the video screen behind him.
A couple of articles have crept out over the last few days that relate to online operations on Oracle Database 12c Release 2 (12.2). Both of them are pretty small in terms of what you have to do, but are pretty awesome in terms of impact, so I’m giving them the official thumbs-up! 🙂
The first one is about moving tables online.
I wonder if this was a 12.1 feature that got pulled? In 12.1 we got to
move partitions and sub-partitions online, but being able to move a table as an online operation is great. Saves you having to mess around with DBMS_REDEFINITION for a bunch of tasks.
The second one is about converting non-partitioned tables to partitioned tables.
This is pretty cool too. For one, you can use a single command to do it now, rather than having to use
EXCHANGE PARTITION or DBMS_REDEFINITION to do it. What’s more, it can be done online!
As I’ve said many times before, it’s these convenience new features that usually have a bigger impact on my day-to-day life than the big sexy features.
