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.

Oracle Tidbits: November 2021 #OraTidbit

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

#OraTidbit #OracleCloud #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 #OracleCloud #AutonomousDB You can make your Java application connect to Oracle Autonomous Database using TLS instead of mTLS for secure, encrypted communications without a wallet.
#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 #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 #OracleCloud Starting November 3, 2021, Oracle defined backup policies will no longer include full volume backups. All volume backups generated from Oracle-defined policies will be incremental backups. This change applies to existing volume backup policy assignments and new volume backup policy assignments.
#OraTidbit #OracleCloud #AutonomousDB can import JSON data from Cloud Object Store into a table. This import method supports all the Cloud Object Stores supported by Autonomous Database.
#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 #AutonomousDB now supports Blockchain tables. Blockchain tables are insert-only tables that organize rows into a number of chains.
#OraTidbit #OracleCloud Shielded instances harden the firmware security on bare metal hosts and virtual machines (VMs) to defend against malicious boot-level software. Shielded instances use the combination of Secure Boot, Measured Boot, and the Trusted Platform Module (TPM) to harden the firmware security on your instances.
#OraTidbit #OracleCloud #AutonomousDB supports immutable tables. Immutable tables are read-only tables that prevent unauthorized data modifications by insiders and accidental data modifications resulting from human errors.
#OraTidbit #OracleCloud A cluster network is a pool of high-performance computing (HPC), GPU, or Optimized instances that are connected with a high-bandwidth, ultra-low-latency network. Each node in the cluster is a bare metal machine located in close physical proximity to the other nodes.
#OraTidbit #OracleCloud schedule-based autoscaling of the instance pool is ideal where demand behaves predictably based on a schedule, such as a month, date, or time of day. A schedule-based autoscaling configuration can have multiple autoscaling policies, each with a different schedule and target pool size or lifecycle action.
#OraTidbit #AutonomousDB When you initiate certain operations that take some time to complete, including scaling the system (Scale Up/Down) or performing a manual backup, these operations do not prevent you from performing other operations.
#OraTidbit #OracleCloud Verrazzano is an end-to-end enterprise container platform for deploying cloud-native and traditional applications in multicloud and hybrid environments.
#OraTidbit #OracleCloud Data Labeling is the process of identifying properties of documents, text, and images and annotating them with those properties.
#OraTidbit #OracleCloud #OCI Certificates provides organizations with certificate issuance, storage, and management capabilities, including revocation and automatic renewal. If you have a third-party certificate authority (CA) that you already use, you can import certificates issued by that CA for use in an Oracle Cloud Infrastructure tenancy.
#OraTidbit #OracleCloud #AutonomousDB DBMS_LDAP and UTL_TCP packages are now available with restrictions. UTL_TCP restrictions include only 443 (HTTP) 25 and 587 (SMTP) are the allowed ports. For DBMS_LDAP the only allowed port is 636.
#OraTidbit #OracleCloud These PL/SQL packages are not available on
#AutonomousDB DBMS_DEBUG, DBMS_DEBUG_JDWP, DBMS_DEBUG_JDWP_CUSTOM, DBMS_PIPE, UTL_INADDR.
#OraTidbit #OracleCloud #AutonomousDB You can set up Database Actions for database users of Autonomous Database. Database users are not service administrators who do not have access to the Autonomous Database service console. Database Actions provides development tools, data tools, administration, and monitoring features for Autonomous databases.
#OraTidbit #OracleAPEX The Oracle APEX Application Development service provides a preconfigured, fully managed, and secured environment in Oracle Cloud to build and deploy world-class applications. After signing up for your Free Tier account, you can easily create an APEX Service that is free for an unlimited time.
