oracle 12c release date

Caching intermediate, partial results in memory increases the performance of complex, mission-critical operations and optimizes I/O resource consumption. Managed and unmanaged ODP.NET support new Entity Framework Code First features with Oracle databases. These features give you more granular control over your templates and the HTML that the Application Express engine produces. The database is using time zone file version 26 and the target 19 release ships with time zone file version 32. This document contains the following topics: Preinstallation Requirements for Release 12.2, Installation, Configuration, and Upgrade Issues for Release 12.2. This feature improves connection times and parallel processing times by pre-creating process resources. This feature enhances privilege analysis to capture privileges for the following: New tables are introduced to help customers easily identify unused granted privileges. Real-Time Automatic Database Diagnostics Monitor (ADDM) in Oracle Database 12c Release 1 (12.1) - Get up-to-the-minute analysis from ADDM, rather than waiting for the next AWR snapshot. This feature enables the rolling upgrade of a CDB with PDBs that use different character sets. Note, not all releases are eligible for Extended Support (i.e. SQL*Plus can now use Oracle Database techniques such as pre-fetching, array fetching, and statement caching. Indexes consume a large amount of storage within many databases. Prioritized rebalancing is a feature of Oracle Flex ASM disk groups in which some file sets are rebalanced before other file sets. The Oracle XQuery Java engine is extended to provide limited support for the forthcoming XQuery 3.0 recommendation, the XSLT 2.0 completion, and the XQuery 3.0 subset.

Oracle 12c's TOP features are as follows. Normal MDATA sections can be updated without reindexing the entire document, but there is a performance cost for doing so. Starting with Oracle Database 18c, Oracle Corporation releases Release Updates (RUs) and Release Update Revisions (RURs). The automated capability of ADO depends on the Heat Map feature that tracks access at the row level (aggregated to block-level statistics) and at the segment level. Roll forward phase for the destination data state to catch up with the source data. You can now query and update LOB data using a LOB locator selected from a database link to a remote database. In prior releases, such a configuration had to be established manually and required postinstallation setup steps. This feature leverages Nashorn (the JavaScript engine on the JVM) to support the execution of JavaScript modules directly on Oracle Java Virtual Machine (OJVM) in an Oracle database session. An Oracle ACFS loopback device is an operating system pseudo-device that enables an Oracle ACFS file access as a block device. Qn CYyyyy: Date falls within the Calendar Year specified. Many XML documents are a concatenation of multiple documents of the same type. Using resource groups, Oracle Clusterware provides an intuitive model to manage and monitor an application composed of various resources as a single composite entity. This feature also enables automated deep rotation of data encryption keys used by TDE tablespace encryption in the background with zero downtime. Use a gMSA account name (including the domain name) that consists of less than 15 characters. This feature enables you to build location-transparent applications that can aggregate data from multiple sources that are in the same data center or distributed across data centers. Providing longer identifiers gives customers greater flexibility in defining their naming schemes, such as longer and more expressive table names. The Oracle Trace File Analyzer (TFA) Collector allows you to choose between automated and manual collection of diagnostic data. Applications that use ReFS experience better scalability using Oracle Database. This results in better database performance and more effective system utilization. This feature enables Oracle Cloud support for Oracle Database over SQL*Net. SDL developed the original version of the Oracle software. Logical standby databases support such a primary database. SQL profile recommendations implemented on the primary database are applied to the Active Data Guard standby using the redo apply mechanism. Additionally, we will at times make available Innovation Releases as part of the Autonomous Database Cloud Services.

The Oracle ACFS compression project improves both Oracle Database and general purpose file storage. Running this command allows RMAN to take a backup of a sparse database or data file (this can be a pluggable database (PDB)). Oracle sharding also supports data placement policies (rack and geo awareness) and all deployment models (for example, on-premises and public or hybrid clouds). Jobs cannot execute until the required resources are available. JSON and GeoJSON are among the most common data exchange formats for web and mobile applications. 12.2.0.1, 18c). Only a physical standby database can be created when connected to a physical standby database as the target database. Support for Java SE 8 provides portability of Java applications and libraries and compliance with the latest Java standards. Java containers, frameworks, and applications looking to handle FAN events can use these APIs to subscribe to Oracle Database RAC FAN events for building high availability solutions. Oracle Database audit trail now includes the predicate or WHERE clause added by Oracle Virtual Private Database (VPD) policies. Oracle Data Provider for Microsoft .NET (ODP.NET) Managed Driver adds new feature support matching the same functionality available in ODP.NET Unmanaged Driver. The most recent changes will be highlighted with a "New" or "Updated" icon to help you quickly identify the modifications. Now you can also specify high compression. In prior releases, it was necessary to change the application to include calls to start and stop debugging. No other rights are granted Oracle reserves the right to change this plan with changing business requirements. This feature enables performance tuning and troubleshooting for workloads executing on a PDB. Resilient File System, which is a new file system available on Windows 8 and Windows Server 2012, is not supported for this release. Thereafter, any update on the primary instance is replicated to the secondary instances. This feature also alleviates security concerns with public Database as a Service (DBaaS) and this feature helps in cloud adoption. This feature simplifies the distribution of data files that can be loaded from different directory paths on different machines. Additionally, Transparent Application Failover (TAF) is extended with Transaction Guard to fail over more OCI-based applications transparently. In previous releases, the Oracle Data Guard broker lacked a ConfigurationWideServiceName configuration property shared by all members. The account is automatically locked if a log in does not occur in the specified number of days. This feature extends the capabilities of Oracle Database File System (DBFS) to provide file locking support for POSIX-style applications that use dbfs_client as a front-end interface, and for applications that use the PL/SQL interfaces to DBFS. Enterprise quality. Secondary instances can be promoted to the primary role whenever an existing primary instance fails or is removed by a cluster administrator. This is especially useful when comparing Big Data results with structured information in operational systems and data warehouses. Native support for these formats simplifies application development and the creation of REST data services. New syntax is added to let users specify new file names, or file name transforms, for the data files in a transportable tablespace job. Analytic views can be queried with simple SQL queries, simplifying application development by eliminating the need for complex SQL generators. and its affiliates are not responsible for and expressly disclaim all warranties of any This feature also reduces the overhead for space consumption because there is no requirement to allocate storage for unused, empty space. Unlike an architecture based on Oracle Real Application Clusters (Oracle RAC), applications that use sharding must have a well-defined data model and data distribution strategy (consistent hash, range, list, or composite) that primarily accesses data using a sharding key. The database resident Oracle Java Virtual Machine (OJVM) now supports Java SE 8. Sentiment analysis provides identification of positive and negative trends associated with search terms. The Direct NFS client now supports Parallel NFS. These releases are issued quarterly; some of these releases have updates issued prior to the next quarterly release.
