Starting with Oracle database 12c unharness two (12.2), we are able to truncate the come back string of LISTAGG perform, to suit inside the utmost length supported for the come back information kind and show a truncation literal to point that the come back worth was truncated.
In Oracle12c Release2 (12.2.0), most length of symbol names for many varieties of information objects has been hyperbolic to 128 bytes/chars from thirty bytes/chars.

When we produce a tablespace, we are able to specify that each one tables and indexes, or their partitions, created during a tablespace area unit compressed by default.
During tablespace creation, we are able to specify the sort of table compression mistreatment the DEFAULT keyword, followed by the table compression clause as well as the compression kind. we are able to additionally specify the sort of index compression mistreatment the DEFAULT keyword, followed by index compression clause and also the index compression kind.
Release two incorporates important support enhancements for storing and querying JavaScript Object Notation (JSON) documents for Oracle information.
Sharding : Sharding is an application-managed scaling technique mistreatment several freelance databases. the information is split into multiple databases (called shards). every information holds a set of the information, this may be either be vary or hash. we are able to additionally split the shards into multiple shards because the information volume or access to the present information grows. Shards then is replicated for handiness and quantifiability reasons.
We will have a piece information with tablespace sets, and up to a thousand shards. DDL applied on one shared are pushed to the others. Some common information is duplicated.
Nonpartitioned tables is stirred as an internet operation while not interference any simultaneous DML operations. A table move operation currently additionally supports automatic index maintenance as a part of the move. Use the ALTER TABLE...MOVE statement to maneuver a table to a brand new phase or tablespace.
Password file is managed and transported via the Redo mechanizm.
