Release Update 19.11 Features
Application Continuity Protection Check
Application Continuity Protection Check (ACCHK) provides guidance on the level of protection for each application that uses Application Continuity and assists you to increase protection, if required.
ACCHK identifies which application configuration is protected to help you make an informed decision about which configuration to use for maximum protection or how to increase protection level for an application configuration. ACCHK also provides diagnostics for an unsuccessful failover.
Immutable Tables
Immutable tables are insert-only tables in which existing data cannot be modified. Deleting rows is either prohibited or restricted based on the insertion time of the rows.
Immutable tables protect data against unauthorized modification by insiders. This includes database administrators or compromised users who have access to insider credentials. Immutable tables also prevent accidental data modification that may be caused by human error.

New Database Initialization Parameter for Database Resident Connection Pooling (DRCP)
A new database initialization parameter, DRCP_DEDICATED_OPT, has
been added to configure Database Resident Connection Pooling (DRCP).
With DRCP, when the number of application connections to the broker is less
than the maximum pool size, a "dedicated optimization" makes DRCP behave like dedicated
servers. With this optimization, DRCP tends towards a one-to-one correspondence between
application connections and DRCP server processes even if those processes are not
currently doing database work. Setting DRCP_DEDICATED_OPT to
NO turns off the optimization and reduces the tendency of the pool
to grow towards its maximum size until necessary. This helps keep the number of DRCP
server processes small when statement execution concurrency is low, therefore reducing
memory usage on the database host.

Oracle Fleet Patching and Provisioning Zip Copy Image Transfer
Starting with Oracle Grid Infrastructure 19c Release Update (19.11), Oracle FPP enables you to install the gold images without transferring them to the target host. You can make the gold images available as zip files, either on a shared file system (NFS) or target hosts.
The Zip copy image transfer feature avoids errors and timeout for deployments with low bandwidth or high latency networks between the Oracle FPP Server and targets. This enables deployments in different data centers.
