For product longevity and patching, Oracle strongly recommends upgrading to 19c which is the Long Term Release with a support end date of April 30, 2027 (or April 30, 2025 if you choose not to pay Extended Support fees or purchase a ULA). Corporation. ODP.NET then stops allocating new connections and close connections returned to the pool from that particular instance. This capability is built on top of Oracle Direct NFS Client using the NFSv4 and NFSv4.1 protocols. you shall be responsible to take all appropriate fail-safe, backup, redundancy, and Generate the PL/SQL wrapper and grant the proper permissions. Improved manageability of Active Data Guard databases through support of application tuning. Even if a user opens the wallet by starting an auxiliary instance, the DUPLICATE command restarts the auxiliary instance many times during the command execution. By supporting higher numbers of PDBs for each CDB, you have fewer CDBs to manage and thus benefit from further reductions in operating expenses. These releases have 5 years of Premier Support followed by 3 years of Extended Support. These improvements include: This feature makes it easier to work with JSON documents stored in an Oracle database and to generate JSON documents from relational data. Recovery Manager, Partitioning. LISTAGG aggregates the values of a column by concatenating them into a single string. Oracle customers have access to electronic support through My Oracle Support. Only the delta storage file (changes happened using the sparse database) is backed up. This enhancement provides an up front check on the available disk space for the auxiliary instance, before RMAN executes table recovery. The column-level collation allows you to declare the sort ordering on a column level, using syntax and semantics compatible with the ISO, IEC and ANSI SQL standard. Oracle Database 12c Release 1 (12.1.0.1) supported up to 252 PDBs for each CDB. The protocol ensures that user transactions are executed no more than once. This feature provides support for an additional metric type, Metric2, for Oracle ACFS plug-ins. This feature also enables routing for queries that do not specify a shard key. Stores data in a compression unit, which is a special on-disk format. By enabling easier and more efficient methods to enhance the DUPLICATE command to create far sync standby support and by allowing creation of a regular database, this feature increases the benefits for deploying Oracle Data Guard by offloading processes to the standby database. Map visualization is a Java EE (Java Platform, Enterprise Edition) application that can be deployed to supported Java EE containers, such as WebLogic Server (WLS), Apache Tomcat, and JBoss. The existing CAST function is enhanced to return a user-specified value in the case of a conversion error instead of raising an error. Oracle Database Vault policy authorization delegation is also allowed. This reduces the time to import the table data. The existing NET_TIMEOUT redo transport attribute allows you to specify how long the primary database should wait for a response from each synchronous standby database. Java and PL/SQL network feature editing APIs are added to Oracle Spatial and Graph Network Data Model that allows you to edit features, define and enforce rules regarding what editing can be performed, and create both in-memory and in-database networks. In prior releases, it was necessary to change the application to include calls to start and stop debugging. This feature provides advanced security Transparent Data Encryption (TDE) support for these encryption algorithms: This feature includes support for both encryption and hashing algorithms and is available for use with data-at-rest encryption. With this enhancement, Oracle Database conforms to the latest version of the Unicode Standard. The result can be stored on a central server and is trimmed to reduce data upload size. For this release, IPv6 networks are not supported for Oracle Real Application Clusters (Oracle RAC) private interconnects on Microsoft Windows platform. Share-based Instance Caging is supported only on Oracle Solaris and Oracle Linux. The partition maintenance operations SPLIT PARTITION and SPLIT SUBPARTITION can now be executed as online operations for heap organized tables, allowing the concurrent DML operations with the ongoing partition maintenance operation. You can also change PL/SQL programs to reflect changed requirements by making changes at far fewer sites. Starting with Oracle Database 12c Release 2 (12.2), DBAs can execute the SQL Performance Analyzer (SPA) and SPA Quick Check from Oracle Enterprise Manager Database Express (EM Express). This also provides the ability to protect data that belongs to one PDB from being accessed by users connected to another PDB. This feature allows more users of Hadoop to combine map-reduce processing with the essential database qualities that many applications require. OLTP applications designed for Oracle sharding can elastically scale (data, transactions and users) to any level, on any platform, simply by deploying new shards on additional stand-alone servers. Native support for these formats simplifies application development and the creation of REST data services. STS capture now includes additional statistics that are specific to Exadata, SQL Monitoring, and In-Memory Database. Oracle 12c (version 12.2.0.1) was released in March 2017 and is widely used across businesses in both Standard and Enterprise Edition versions. Constraints defined as declarative and non-enforced on both internal and external tables are used more comprehensively for query processing optimizations. Loop unrolling is performed on small, frequently executed loops. registered trademarks of SPARC International, Inc. AMD, Opteron, the AMD logo, and the Using Transaction Guard, a transaction manager can now return reliable outcome for XA transactions to the user. This issue is tracked with Oracle bug 20918120. When enabled, this feature provides the database and replication administrators with more detail about the logical change records being processed. PL/SQL APIs can now perform enqueue and dequeue operations for ADT and RAW payload in sharded queues. There are two types of Oracle Database releases: Long Term Release and Innovation Release. Now the concept of g ( grid) in 10g and 11g has been replaced by c ( cloud ). A fine-grained information about which indexes are used and how frequently they are used allows you to eliminate infrequently used indexes. Support for end-to-end tuning and testing of workflows when used with SQL Performance Analyzer, or otherwise. Using the correct setup, no errors are reported for either new, incoming work, or for existing work while maintenance is in progress. Prior to this release, the only form of advanced index compression was low compression. Oracle Database Resource Manager (the Resource Manager) can now manage memory usage between pluggable databases (PDBs) within a multitenant container database (CDB). Indexes consume a large amount of storage within many databases. This includes the ability to retrieve SDO_GEOMETRY data as a JSON object, to get the results of a spatial query as a JSON document, and to store, index and query GeoJSON documents. Broker support also adds substantial simplification to the rolling upgrade process by transparently handling redo transport destination settings and other tasks. The Microsoft handle utility is required for proper operation of Oracle ACFS High Availability resources managed by Oracle Clusterware. This is not always the case, however, in an Oracle Active Data Guard environment where only a subset of PDBs are required to support read-only operations (a production offload feature versus an HA service level). Using materialized view logs for delta computation together with the stale materialized view, the database can compute the query and return correct results in real time. Analytic views provide a business intelligence layer over a star schema, making it easy to extend the data set with hierarchies, levels, aggregate data, and calculated measures. For example, if there are three nodes A, B, C, and A is down at some point in time, then connections are allocated from nodes B and C, first, and then finally to node A. Oracle Clusterware application clusters provides an alternative solution to other light-weight clustering solutions to ease the adoption and configuration of Oracle Clusterware for the purpose of managing and deploying an Oracle Clusterware-based cluster by requesting user input only for those components that are essential for managing non-database applications. Administrators now have the flexibility to use their preferred NFS path format. However, there are plenty of manual steps that are prone to errors. Oracle Database 10g and Oracle9i Database) have used suffixes of "g" and "i" which stand for "Grid" and "Internet" respectively. Users connected through a physical standby only role continue to be disconnected. Nonpartitioned tables can be converted to partitioned tables online. You can configure cluster nodes to use either IPv4 or IPv6 based IP addresses on a private network, and more than one private network can be used for a cluster. In Oracle Database 12c Release 1 (12.1), this was enhanced to use one preferred destination, and the second as an alternate destination, with automatic reconfiguration and simple failback when the initial redo destination was once again available. With this new functionality, these temporary tables can reside completely in cache without the need to write them to disk. The process consists of loading your JavaScript code as Java resource in a user schema using the loadjava utility and then invoke it through a SQL wrapper. A one command orchestration focuses on the best possible application experience, as opposed to the maintenance applied, as quickly as possible, with no consideration for the applications. In Windows 7 and Windows Server 2008 R2, Microsoft introduced virtual accounts, which are managed local accounts that use computer credentials to access network resources. Oracle and Java are registered trademarks of Oracle and/or its Oracle Data Guard now supports multiple failover targets in a fast-start failover configuration. With the pluggable database (PDB) lockdown profile, you can specify a simple lockdown level for a given multitenant container database (CDB). We decided to not promote our Database 20c Preview version to General Availability. The AWR_PDB_AUTOFLUSH_ENABLED initialization parameter enables you to specify whether to enable or disable Automatic Workload Repository (AWR) snapshots for all of the pluggable databases (PDBs) in a multitenant container database (CDB) or for individual PDBs in a CDB. 12.1.0.2 is in Sustaining Support with Market Driven Support available beginning January 1, 2023 for some platforms. As a completely new IDE that is designed to greatly improve developer productivity, Page Designer enables you to very quickly develop and maintain your Application Express applications. The collection of shards is presented to an application as a single logical Oracle database. It enables developers to optimally address applications where only some of the data needs language or region-specific sorting rules. New syntax is added to let users specify new file names, or file name transforms, for the data files in a transportable tablespace job. Similarly, the PL/SQL Array APIs are exposed to sharded queue JMS users. This enables you to limit the file system expansions and to prevent runaway storage consumption. This feature leads to improved user experience, higher application availability, and improved ODP.NET developer productivity. This issue is tracked with Oracle bug 21888659. Except as expressly permitted in your license agreement or These models are still bundled as a single model to simplify management and deployment as well as to improve performance. The Oracle Trace File Analyzer (TFA) Collector is a diagnostic collection utility to simplify diagnostic data collection for Oracle Clusterware, Oracle Grid Infrastructure, and Oracle Real Application Clusters (Oracle RAC) systems. an applicable agreement between you and Oracle. Provisioning, patching, and upgrading of Oracle Grid Infrastructure releases 12.2, 12.1.0.2, and 11.2.0.4. This limit can only be applied to a PDB, not to the multitenant container database (CDB) or a non-CDB. The new pragma provides a formal way to communicate this message with a power that ordinary external documentation cannot convey. It can be used to rename entire tables or to rename table partitions. The information contained herein is subject to change without notice Dispatcher infrastructure for Direct NFS Client is added in this release. By applying such collations to SQL operations, an application can perform string comparisons and matching in a case-insensitive way, independent of the language of the data. Examples include Project Tracking, Survey Builder, Meeting Minutes, and Group Calendar. In Oracle Database 12c Release 1 (12.1), the Oracle JDBC drivers furnish complete support for the JDBC 4.2 standard through JDK 8 including the setObject() method which complements the getObject() method introduced in the last release of Oracle Database. Customers are able to identify and prioritize workloads using services without over sizing the database connections. It also automatically copes with the unplanned partition key values without the need of a DEFAULT partition. Two principle mechanisms, a system inherent automatic mechanism and a user input-based mechanism exist to provide respective guidance. Reuse data-bound JavaScript code in the database. The support for Unicode Collation Algorithm (UCA) is also updated to conform with UCA 7.0. Oracle Data Guard broker users can now use the DGMGRL command-line interface to configure and implement the enhanced ALTERNATE redo destinations capability. In-Memory Column Store allows objects (for example, tables, partitions, and subpartitions) to be populated in-memory in a compressed columnar format. A database automatically achieves the state that, no matter how many edition-based redefinition exercises are done, the total number of editioned objects is identical to what it would be if the database were flattened to just a single edition. With Data Guard configurations, you can either encrypt the physical standby first and switchover, or encrypt the primary database, one tablespace at a time. Support for distributed caches, in conjunction with improved path computation heuristics, improves the performance of network and route calculations. Customers benefit from improved query performance for statements that include expressions. In this architecture, the updates made on the read-write instances are immediately propagated to the read-only instances on the Leaf Nodes, where they can be used for online reporting or instant queries. This new feature significantly reduces downtime by leveraging the clone functionality to relocate a pluggable database (PDB) from one multitenant container database (CDB) to another CDB. Oracle Automatic Storage Management Administrator's Guide, Oracle ACFS Command-Line Tools for Replication. Through these standards-based interfaces, applications using Oracle Spatial and Graph map visualization can make map data in Oracle Database available to other applications through OGC Web Map Services and Map Tile Services. The ability to run JavaScript in the database provides the following benefits: In this release, the Java version of the Oracle XSL processor is extended to provide complete support for the W3C XSL 2.0 Standard. This page provides you with the most commonly used Oracle date functions that help you handle date and time data easily and more effectively. Oracle Database 12c Release 2 (12.2) now supports having thousands of pluggable databases (PDBs) in a single multitenant container database (CDB). Administrative users can connect to Oracle Database using SSL and Kerberos schemes, even when an instance is not yet started. It is now possible to configure multiple observers within a single Oracle Data Guard broker configuration. SPARQL Update enables a single SPARQL request to perform a number of operations: Application developers can now be more productive with a single SPARQL request to the Oracle Database RDF graph store. A shard topology cache in the connection layer is used to route the request directly to the shard where the data resides. If the database uses the In-Memory Column Store, you can set im_imcu_count to the number of In-Memory Compression Units (IMCU) in the table or partition, and set im_block_count to the number of blocks in the table or partition. Compile PL/SQL packages, procedures, and functions in addition to the current capability of capturing execution privileges. With this feature, JDBC drivers support a BigSCN of 8 bytes. The Oracle ACFS loopback device enables high performance block storage I/O between the client and the server components. Import sees the partition of data that is loaded into the entire table. Development of virtual machine (VM) management capabilities are using a dedicated VM Manager Agent for GI that interfaces with the Oracle Virtual Machine (Oracle VM) Manager, thus enabling the management of non-GI VM's as clusterware resources. Premier Support (PS) ended 31-Jan-2015 and one year of free Extended Support (ES) was in effect until Dec 31, 2018. The architecture allows for the distribution of a high number of processing engines dedicated to parallel execution of queries. However, no new optimizer or functional fixes are included. There are important high end customers who make use of PL/SQL APIs to enqueue and dequeue ADT or RAW payload in unsharded queues. Parallel load and parallel insert is now supported for domain indexes which is especially beneficial for Oracle XML DB users. Coverage also excludes any updates related to cryptography and network encryption. Users are now able to use automatic failover in the guaranteed zero data loss mode utilizing multiple fast-start failover targets when there are multiple synchronous destinations. This feature improves the user experience and facilitates improved reporting and query capabilities on an Active Data Guard standby during role transitions. The primary benefit is to extend the ease of advanced analytics development from the R domain to Oracle Database. SYSRAC is a new role for Oracle Real Application Clusters (Oracle RAC) management. The SimpleFAN library (simplefan.jar) is enhanced with a new capability to identify UP events. Fees will be required beginning May 01, 2025 through April 30, 2027, Error Correction / Patching is available through April 30, 2027 with paid ES. External tables are used by both SQL*Loader and Oracle Data Pump, and thus also by the ORACLE_LOADER and ORACLE_DATAPUMP access drivers. With this new feature, you can control the SQL execution plans of recursive SQL statements generated from the CONTAINERS () query. When the database detects a band join, the database evaluates the costs of band joins more efficiently, avoiding unnecessary scans of rows that fall outside the defined bands. Server releases always include the native word size client (e.g. These enhancements simplify and improve ease-of-use for the SET NEWNAME, MOVE and RESTORE+RECOVER commands. Developers of location-based services, data publishers in state and local government, and architects of web services and more traditional applications can all easily integrate these mapping features into their web-based solutions. However, a specific focus of this project for Oracle Database 12c Release 2 (12.2) is to deliver data compression that is optimized for data files, archive logs, data pump files, and Oracle Recovery Manager (RMAN). TFA encapsulates diagnostic data collection for all clusters and Oracle Database components on all servers into a single command executed on one server only. While similar to the diagnostic collection feature, the Oracle Trace File Analyzer (TFA) Collector allows centralization and automatic collection of diagnostic information. This feature leverages the new switch service functionality to reuse pooled connections across multitenant (pluggable) databases. Through the implementation of this standard, raster data stored in Oracle Spatial and Graph can be made accessible to a wide range of applications on the web. Alternatively, you may add ORA_DBA group manually and then retry DBCA. This enables you to capture the performance data to the Automatic Workload Repository (AWR) for an Active Data Guard standby database and to run Automatic Database Diagnostic Monitor (ADDM) analysis on the AWR data. All rights reserved. SQL profile recommendations implemented on the primary database are applied to the Active Data Guard standby using the redo apply mechanism. Some JDK 8 features, including JavaFX, command line tools, Java tools, GUI interfaces, HotSpot, Mission Control, and so on are not supported in OJVM. The federation of PDBs improves operational efficiency to maintain multiple application tenants from a single master. This improved management capability of common objects not only saves time, but also lowers the risk of having different security profiles on similar PDBs. Redo Apply can now run on all or some standby instances as configured by the user. Multiple failover targets increase high availability by making an automatic failover more likely to occur if there is a primary outage. The concept of an alternate destination for redo transport was first introduced in Oracle Database release 9.2 and was designed to work as a single pair of destinations with simple failover when the initial destination was no longer available. The tool can do the following: The Web services callout supports basic and advanced Web services authentication (for example, SSL). Data-dependent caching leads to consistent response times when accessing data across Oracle RAC database instances running in the cluster. This document contains the following topics: Preinstallation Requirements for Release 12.2, Installation, Configuration, and Upgrade Issues for Release 12.2. For this feature, you do not need to specify the shards on which the query runs. The map visualization feature in Oracle Spatial and Graph enhances the spatial data management capabilities by providing a generic web-based means of delivering and viewing any spatial and geographic data in the database. The high level of advanced index compression provides significant space savings while also improving performance for queries that are executed using indexes. In Oracle Database 12c Release 2 (12.2), Oracle Data Guard broker can publish a service on each member in a configuration with a unified service name. The non-intrusive configuration of Oracle Universal Connection Pool (UCP) simplifies manageability for custom and packaged Java applications for which source codes are not available. Improved application performance of Active Data Guard and primary database workloads. This feature also enables parallel loading of XML Data with partitioning and XMLIndex support for inter- and intra-partition parallelism. This feature enables performance tuning and troubleshooting for workloads executing on a PDB. This feature enables the consolidation of databases that have different character sets, time zone file versions, and database time zones into a CDB. Other benefits include: Application Continuity recovers incomplete requests from an ODP.NET, unmanaged driver perspective and masks many system failures, communication failures, hardware failures, and storage outages from the user. The Oracle Universal Connection Pool (UCP) for JDBC client is also able to recognize shard keys specified in the connection URL. The concept of pluggable databases (PDBs) was introduced with Oracle Database 12c (multiple databases sharing a single database instance). to the U.S. Government. Obtain the Web Services Description Language (WSDL) of a published Web service server furnished as a parameter. My Oracle Support provides customers with access to over a million knowledge articles and a vibrant support community of peers and Oracle experts. A new privilege INHERIT REMOTE PRIVILEGES enables you to use a connected user database link from within a definer's rights procedure. To support RMAN backup with sparse files, this feature introduces a new command BACKUP AS SPARSE BACKUPSET
