#OraTidbit #AutonomousDB #NewFeature When you provision or clone an Autonomous Database instance you can select a patch level to apply upcoming patches. There are two patch-level options: Regular and Early.
#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 Database In-Memory “Base Level” feature allows the use of Database In-Memory with up to a 16GB column store without having to license the option. This #db21c feature is available from 19.8.
#OraTidbit #NewFeature #db19c #db21c Gradual Database Password Rollover for Applications feature allows an application can change its database passwords without an administrator having to schedule downtime. Use the PASSWORD_ROLLOVER_TIME password profile parameter. This #db21c feature is available from 19.12.
#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 #AutonomousDB #New When you provision or clone an Autonomous Database instance you can select a patch level to apply upcoming patches. There are two patch-level options: Regular and Early. The Early patch level allows you to use and to test upcoming patches before they are applied to all systems.
#OraTidbit #AutonomousDB #New When you enable Autonomous Data Guard, the system creates a standby database that is continuously updated with the changes from the primary database. You can enable Autonomous Data Guard with standby in the current region, a local standby, or with standby in a different region, a cross-region standby. You can also enable Autonomous Data Guard with both a local standby and a cross-region standby.

Oracle Tidbits: June 2021 #OraTidbit

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

#OraTidbit #OracleCloud Exadata Cloud Service has a non-rolling infrastructure patching option. This option allows you to reduce the total time your system is undergoing quarterly maintenance but does involve system downtime.
#OraTidbit #OracleCloud AWR Viewer in Database Management integrates performance and data visualization tools, displaying the historical performance data from AWR snapshots in easy-to-interpret charts. You can use the #OCI Database Management service to monitor and manage your on-premises Oracle Databases.
#OraTidbit #OracleCloud Data Flow is a fully managed service for running Apache Spark applications. It allows developers to focus on their applications and provides an easy runtime environment to execute them. There is no need to spend any time on the underlying infrastructure, cluster provisioning, or software install.
#OraTidbit #OracleCloud The Data Science service enables data science teams to build, train, and manage machine learning and artificial intelligence models on Oracle Cloud. Notebook Sessions provide a JupyterLab interface where data scientists can write and execute Python code to build, train, evaluate, and explain models using a wide variety of pre-installed open-source and Oracle machine learning libraries.
#OraTidbit #AutonomousDB You can use Autonomous Database as a Recovery Manager (RMAN) recovery catalog. Recovery Manager (RMAN) recovery catalog is preinstalled in Autonomous Database in schema RMAN$CATALOG. The preinstalled catalog version is based on the latest version of Oracle Database and is compatible with all supported Oracle database versions.
#OraTidbit #OracleCloud Oracle Integration is a secure, unified platform that lets you connect cloud and on-premises applications, automate business processes, gain insight into your business through business metrics analysis, and develop web and mobile applications.
#OraTidbit #OracleCloud Oracle Integration includes a portfolio of recipes for integrating different applications. Think of a recipe as a template or pre-assembled solution that gives you a head start in building your integrations. You can start with a recipe, and then customize it to fit your needs and requirements.
#OraTidbit Application Continuity Protection Check (ACCHK) (#db21c feature backported to 19.11) provides guidance on the level of protection for each application that uses Application Continuity and assists you to increase protection if required.
#OraTidbit Oracle database has two core mechanisms to work with data in OCI object stores – DBMS_CLOUD package or manually defining external tables. The DBMS_CLOUD package is available in Oracle Database 19c, starting with version 19.10.
#OraTidbit #AutonomousDB Automatic partitioning analyzes and automates partition creation for tables and indexes of a specified schema to improve performance and manageability in Autonomous Database. Automatic partitioning, when applied, is transparent and does not require any user interaction or maintenance.
#OraTidbit #AutonomousDB Automatic partitioning uses a single-column partition key combined with single-level partitioning. Partition methods: AUTOMATIC INTERVAL, LIST AUTOMATIC, HASH. Automatic partitioning analyzes application workload and finds the optimal partitioning strategy.
#OraTidbit #AutonomousDB Graph Studio provides graph data support in Oracle Autonomous Database to model, create, query, and analyze graph data. Graph Studio includes notebooks, developer APIs for executing graph queries using PGQL, nearly 60 built-in graph algorithms, and offers dozens of visualizations including native graph visualization.
#OraTidbit #AutonomousDB Database Actions is a web-based interface that uses Oracle REST Data Services to provide development, data tools, administration, and monitoring features for Oracle Autonomous Database. The main features include executing your SQL statements and scripts, creating Data Modeler diagrams, developing RESTful web services, managing JSON collections, and using the Data Load, Catalog, Data Insights, Business Models, and Data Transforms tools to load data from local and remote sources, view data in your tables and views, view objects in your data dictionary, and organize, analyze, and transform your data.
#OraTidbit #db21c Database Nest is an infrastructure that provides operating system resource isolation and management, file system isolation, and secure computing for CDBs and PDBs. This infrastructure enables a database instance to run in a protected, virtualized environment.
