Oracle Tidbits: December 2021 #OraTidbit

Oracle *daily* TidBits (#oratidbit) were published on Facebook &Twitter during weekdays in December 2021. I hope you find these helpful to learn something new or remind you of its existence and use.

#OraTidbit #NewFeature #db19c #db21c Gradual Database Password Rollover feature allows an application to change its database passwords without scheduling downtime. Use the PASSWORD_ROLLOVER_TIME password profile parameter. This #db21c feature is available from 19.12.
#OraTidbit #AutonomousDB #New When you provision or clone an Autonomous Database instance you can select a patch level to apply upcoming patches. Regular and Early. The Early patch level allows you to use and test upcoming patches before they are applied to all systems.
#OraTidbit #NewFeature #db19c #db21c 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. This #db21c feature is available from 19.11.
#OraTidbit #NewFeature #db19c #db21c 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. This #db21c feature is available from 19.11.
#OraTidbit #OrclAPEX Oracle APEX Application Development (APEX Service) is a feature-scoped service of Autonomous Database that enables developers to rapidly build and deploy low-code APEX applications. APEX Service supports Oracle REST Data Services endpoints.
#OraTidbit #OracleXE Oracle Advanced Compression, Advanced Security, Database In-Memory, Database Vault, Label Security, Multitenant and Partitioning options are included with the Oracle XE release.
#OraTidbit Restricted use licenses for Oracle Advanced Compression and Oracle Advanced Security are granted when performing a migration to OCI using Oracle Zero Downtime Migration or Oracle Cloud Infrastructure Database Migration (DMS).
#OraTidbit #OCI #AutonomousDB You can configure a custom domain name or vanity URL for your APEX apps, Oracle REST Data Services (ORDS), and developer tools by placing an Oracle Cloud Infrastructure Load Balancer directly in front of your Autonomous Database.
#OraTidbit #AutonomousDB #OCI Oracle Cloud Infrastructure Console provides information on Autonomous Database maintenance windows and patch level and provides a customer contacts area to manage the contacts to receive information on operational issues and service announcements.
#OraTidbit #OracleXE Multitenancy is included in XE and you are licensed to create up to 252 PDBs, however, the actual number of PDBs you can create might be less due to XE resource limits.
#OraTidbit #db21c A temporary tablespace can grow to a very large size due to spikes in temporary space usage by queries. Automatic temporary tablespace shrink is a feature that shrinks the temporary tablespace in the background when temporary space usage has subsided.
#OraTidbit The #db21c database incorporates workload monitoring to establish what materialized views are needed. Based on the decisions it makes, materialized views and materialized view logs are created and maintained automatically without any manual interaction.
#OraTidbit #OracleCloud #OCI Oracle Cloud Infrastructure Operations Insights is an OCI native service that provides 360-degree insight into the database and host resource utilization and capacity.
#OraTidbit #OracleCloud In metric-based autoscaling, when system usage meets a specific defined metric threshold, autoscaling dynamically resizes the instance pool in near-real-time. As load increases, the pool scales out. As load decreases, the pool scales in.
#OraTidbit #OracleCloud Shielded instances harden the firmware security on bare metal hosts and virtual machines (VMs) to defend against malicious boot-level software. They use the combination of Secure Boot, Measured Boot, and the Trusted Platform Module (TPM) to harden.
#OraTidbit #OracleCloud A cluster network is a pool of high-performance computing (HPC), GPU, or Optimized instances connected with a high-bandwidth, ultra-low-latency network. Each cluster node is a bare metal machine located in close physical proximity to the other nodes.
