New Auto Upgrade Tool
• Oracle Database Auto Upgrade allows DBAs to upgrade one
or many databases without human intervention
• Allows the DBA to upgrade one or many databases without
human intervention
• The Auto Upgrade utility identifies issues before upgrades,
deploys upgrades, performs post upgrade actions, and
brings up the upgraded Oracle Database
• Currently supports 11.2 and 18c

SQL STATEMENT
SQL Quarantine
• SQL execution plans consuming excessive
resources are quarantined
• It’s prevented from executing again
• Improves overall responsiveness of the
system by stopping “rogue” SQL
statements being continually resubmitted
• DBA can monitor quarantined statements
in V$SQL
• Controlled by DBMS_SQLQ or
DBMS_RESOUCE_MANAGER

Active Data Guard : DML Redirection
• Allows DML to be executed against the standby database
• On execution the DML operation is passed to the primary database
• The primary database performs the operations and generates the redo
• The redo is then applied to the standby and control returned to the
application
• The transaction is fully ACID compliant
• Allows for incidental updates to be run against the standby increasing the
overall flexibility of the disaster recovery architecture

• Support multiple PDB-shards in the same CDB
– Allows consolidation of apps that require separate
databases, but share the same system
• Multiple Table Families
– Support multiple table families where data from
different families reside in the same chunk
• For system-managed sharding method
– Different apps accessing different table families
can now be hosted on one sharded DB
• Propagate parameter setting across shards
– Centrally manage and propagate "ALTER
SYSTEM" parameter setting from shard catalog to
all shards

UPDATE purchaseorder_tab
SET po_document =
json_mergepatch(
po_document,
'{"Special Instructions":null}’
);
24
Partial JSON Update Support
• New SQL function
JSON_MERGEPATCH enables
you to update specific portions of a
JSON document without have to
replace the entire document
• Imagine we need to updates all of
the JSON documents in the
po_document column of the
purchaseorder_tab table to
remove the field "Special
Instructions"

Real-Time Statistics
• Gather statistics as part of conventional DML
(Insert/update/merge)
• Statistics gathered during DML needs to be fast
with negligible overhead
• Only most essential stats are gathered to avoid
catastrophic SQL execution plan performance
regressions (e.g. avoiding out-of-range conditions)
– Min, Max, num_rows, etc.
• Gathering of remaining statistics is deferred
– Automatic statistics gathering job still kicks in as needed
