For example, if the value is set to 30, then the connection pool trusts the validity of the connection for 30 seconds. With this feature, JDBC drivers support a BigSCN of 8 bytes. Online redefinition can restart from most points of failure, eliminating the need to redo the entire operation. With this feature, you can now adjust to changing workloads and comply with Service Level Agreement (SLA) requirements in near real time. If, by virtue of the history of successive edition-based redefinition exercises, and the dropping of the covered objects that these exercises cause, the root edition ends up with no objects at all, then the background process removes it completely from the database. A shard topology cache is used to route the connection directly to the shard where the data resides. These releases are issued quarterly; some of these releases have updates issued prior to the next quarterly release. The purpose of PL/SQL is to issue SQL statements. The source PDB is subsequently dropped. Materializing the values of user-defined virtual columns into the In-Memory Column Store can greatly improve query performance by enabling the virtual column values to be scanned and filtered using In-Memory techniques such as SIMD (single instruction, multiple data) vector processing, just like a non-virtual column.

Supports either asynchronous or synchronous replication for near-zero or zero data loss protection. The federation of PDBs improves operational efficiency to maintain multiple application tenants from a single master. This feature supports Oracle Multitenant and custom consolidated databases, as well as reduces session overhead for all database usage. Since the In-Memory Column Store is allocated from the System Global Area (SGA), it uses main memory which is a limited and expensive resource. Long Term Release: any means. Oracle Corporation suggests that the application always dequeue from sharded queues using the generic type AQ$_JMS_MESSAGE. In the polling model, the application polls for file content changes and Oracle ACFS returns summary messages that identify which files have changed and the location of the changes within each file. ODP.NET then stops allocating new connections and close connections returned to the pool from that particular instance. SQL statements commonly include expressions such as "+" or "-". However, this is limited to the tablespaces and not the entire database. In the Database market, Microsoft SQL Server has a 32.84% market share in comparison to Oracle Database 19c's 0.10%.Since it has a better market share coverage, Microsoft SQL Server holds the 1st spot in Slintel's Market Share Ranking Index for the >Database</b> category, while Oracle Database 19c holds the 53rd . This feature also provides enhancements to NFSv4 support. The PL/SQL-only data types can now be bound using the DBMS_SQL API and by invoking a C external procedure. The concept of pluggable databases (PDBs) was introduced in Oracle Database 12c Release 1 (multiple databases sharing a single database instance). This is especially useful when comparing Big Data results with structured information in operational systems and data warehouses. There is also a new ROLLBACK procedure for the DBMS_REDEFINITION package that initiates the swapping of the redefined table with the original table, therefore effectively rolling back the redefinition changes and returning the table to its original state. Support is provided for both XStream outbound and inbound servers. This feature streamlines the application of additional controls such as encryption and auditing to sensitive data stored inside applications. In addition, a generic Oracle ACFS library is created in Oracle Database that effectively serves as a wrapper for the platform-specific Oracle ACFS C library. This feature enables the rolling upgrade of a CDB with PDBs that use different character sets. Loop unrolling is performed on small, frequently executed loops. Guidance in creating a new resource manager plan through the following: Quick setup when the most common type of resource manager plan must be created, Full setup and how to use the charts to set directives for the plan, Monitoring effectiveness of the currently active plan (Resource Manager Dashboard page and plan home page of EM Express), Full support for multitenant environment using multitenant container database (CDB) level plans (directives are on pluggable databases (PDB)) as well as PDB level plans (directives are on consumer groups). 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. This feature facilitates Oracle Flex Cluster architecture in such a way that it allocates a set of read/write instances running OLTP workloads and a set of read-only database instances across the Hub Nodes and Leaf Nodes in the cluster. 11.2.0.4/12.1.0.2) for the DB Release you are running and then continue the upgrade process by upgrading to the 19c. These profiles are defined in increasing order of restriction. This new view enables DBAs the ability to monitor the progress of their redefinition session and take corrective action if needed. A new Oracle ACFS make file system switch enables you to format an Oracle ACFS file system with 4096-byte metadata structures composed of multiple 512-byte logical sectors on Oracle Automatic Storage Management Dynamic Volume Manager (Oracle ADVM) volumes. Oracle reserves the right to change this plan with changing business requirements. This offering does not include standard Security Patch Updates (SPUs). Page Designer is a modern, intuitive, and exceedingly powerful browser-based Integrated Development Environment (IDE). On-Premises Server Releases (includes client), Lifetime Support Policy - Oracle Technology Products, Database, FMW, EM Grid Control, and OCS Software Error Correction Support Policy (Doc ID 209768.1), Oracle Software Technical Support Policies, https://www.oracle.com/technetwork/database/enterprise-edition/downloads/oracle19c-windows-5539283.html, For details on the Database Suite Lifetime Support Policy (incl. It includes: The map visualization feature supports two-dimensional vector geometries stored in Oracle Spatial and Graph, as well as GeoRaster data and data in the Oracle Spatial and Graph topology and network data models. capability can be put into a file and executed on the DGMGRL command line. Enhancing Direct NFS client to support Parallel NFS extends those benefits to Oracle Database workload when using Direct NFS client with NFS servers that support Parallel NFS. If there are resource limitations, then you can define a resource and set its properties. You can now configure fast-start failover when Oracle Data Guard is running in maximum protection mode. In Oracle Database 12c Release 2 (12.2), multitenant container databases (CDBs) allow pluggable databases (PDBs) to have different character sets as long as the root container has a character set that is the superset of all of the PDB character sets. The protocol ensures that user transactions are executed no more than once. This combination not only makes the partition maintenance operation more flexible and powerful, but also makes it more performant and less resource intensive compared to the two separate data management operations. 18c is now in Sustaining Support. In the latest Oracle Database release, I/O changes take advantage of ReFS scalability features. This extends the usability of DBFS to include applications that use file locks to coordinate application behavior across multiple connections or users. This library supports generic programmatic access to Oracle ACFS, avoiding platform-specific details and dynamic library issues. Nonpartitioned tables can be moved as an online operation without blocking any concurrent DML operations. Provisioning of single-instance Oracle databases on various versions of client clusters. These data are referred to as geospatial coverages. Why-If command evaluations help applications, cluster, and system administrators involved in capacity planning and configuration management to set up and test resource management policies. These are server releases unless otherwise specified. Note, not all releases are eligible for Extended Support (i.e. This new clause parallelizes the creation of a pluggable database (PDB) when creating it from the seed PDB. Additionally, Transparent Application Failover (TAF) is extended with Transaction Guard to fail over more OCI-based applications transparently. By default, TFA considers Oracle Database alert logs, Oracle ASM alert logs, and Oracle Clusterware alert logs for this feature. This restriction is removed with this feature. This feature increases the flexibility of the Oracle Data Guard broker when Oracle Data Guard transport services are used in a heterogeneous configuration where the primary and a Recovery Appliance are of different endianess. Parallel NFS provides significant performance improvements for NFS workloads. If one or both fail to respond within the required 2 seconds, they are marked as failed. I am unable to even launch the tuturial so it's not helpful at all. Prior to the release of Oracle8i Database, no suffixes featured in Oracle Database naming conventions. Caching intermediate, partial results in memory increases the performance of complex, mission-critical operations and optimizes I/O resource consumption. 6.9 years ago. 12.2.0.1, 18c). This feature also enables exchange partition operations to be performed using transportable tablespaces without requiring that the XML being moved be recoded. Support for active duplicate scripts with cross-platform transport. A PDB lockdown profile is a security mechanism to restrict operations that are available to local users connected to a specified PDB. 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. This improves the security profile of each application. This feature enables the use of spatial analysis in applications that currently use or require hash and list partitioned indexes. In addition, CDBs need a way to require certain PDB-level directives (like program global area (PGA) memory limits) to be enforced across all PDBs. Oracle Application Express release 5.0 includes features such as Theme Subscriptions, Template Options, and Theme Styles. Oracle and IBM tend to battle for the mid-range database market on Unix and Linux platforms, while Microsoft dominates the mid-range database market on Microsoft Windows platforms. Start Database Configuration Assistant from the Oracle_home\bin directory. Rapid Home Provisioning provides the following new features: Rapid Home Provisioning facilitates automatic remote provisioning, patching, and upgrade of Oracle Database and Oracle Grid Infrastructure using gold images. The read/write instances are regular Oracle Database instances and can process updates to the data (for example, DML statements UPDATE, DELETE, INSERT, and MERGE), partition maintenance operations, and so on. Now each column can be redacted according to different runtime conditions. By enhancing key client drivers, Oracle Database delivers a solution to: ODP.NET already supports planned outage, which allows a database being brought offline to automatically alert ODP.NET applications of the impending downtime. This feature provides a consistent and transparent implementation of session state fix up. pursuant to the applicable Federal Acquisition Regulation and agency-specific 11.2.0.4 Terminal Release for 11.2. 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). Long Term Releases offer the highest level of stability and the longest length of error correction support. Corporation. Results can be compared to see if there are any differences in privilege usage. The column collation, if not specified explicitly, is inherited from a table default collation, which in turn is inherited from a schema default collation. This enhancement decreases the number of manual steps required by administrators to provision Kerberos authentication for Oracle databases, reducing setup time and decreasing the risk for errors. The new ON STATEMENT refresh capability provides more flexibility to the application developers to take advantage of the materialized view rewrite, especially for complex transactions involving multiple DML statements. Exposing the power of Oracle Database partitioning for external HDFS-based data stores enables orders of magnitude faster query performance and enhanced data maintenance. A much finer degree of data management is possible through this new feature in addition to the SELECT performance enhancements. 12.1.0.2 is in Sustaining Support with Market Driven Support available beginning January 1, 2023 for some platforms. Oracle sharding supports automated deployment, high performance routing, and complete life-cycle management. Oracle Application Express Universal Theme provides a number of new capabilities including Theme Roller, Template Options, responsive design, and accessibility. In this release, formats supported by Oracle Outside-In Technology can be indexed using AUTO_FILTER. This feature set provides a simple to use and fool-proof way for most applications to continue operation during scheduled maintenance. In both use cases, you accept a reduced level of performance compared to OLTP transactions that specify the sharding key. This alleviates the stringent requirement of always having to have fresh materialized views for the best performance. The location of the XML file is specified either in the oracle.ucp.jdbc.oracle.xmlConfigFile system property or in the setXMLConfigFile() API. This scale enables analysis of mobile assets such as cell phones, GPS devices on fleets, automobiles, and individuals, at a massive scale. All ODP.NET specific settings no longer require any operating system level configuration. This issue is tracked with Oracle bug 23630511. This feature adds a new file format that can be written and read by the ORACLE_DATAPUMP access driver in the Hadoop file system. This issue is tracked with Oracle bug 22571230. Any release date ? More complicated examples include PL/SQL functions or SQL functions like LTRIM and TO_NUMBER. Oracle Database now supports Kerberos implementation with Direct NFS communication. If you use Oracle ASM Dynamic Volume Manager (Oracle ADVM) volumes on cluster nodes which is configured with highly available Oracle Automatic Storage Management (Oracle ASM), a deadlock may occur between Oracle ASM or Oracle ADVM and Windows Fast FAT file system. This feature enables better control over which Oracle RAC load balancing nodes the ODP.NET connections are dispensed from to ensure better reliability or performance. Users are relieved of a noticeable burden of comprehension and programming. These APIs allow PL/SQL, Java- and HTML5-based applications to edit network features, simplifying network-based operations and application development. For information about Oracle's commitment to accessibility, visit the Oracle Accessibility Program website at http://www.oracle.com/pls/topic/lookup?ctx=acc&id=docacc. Administrative users can connect to Oracle Database using SSL and Kerberos schemes, even when an instance is not yet started. Oracle ACFS provides a file defragging tool in this release. Enterprise quality. SPM is also enhanced to provide a more selective plan capturing and easier verification for customers. High compression provides even more space savings than low compression. The high level of advanced index compression provides significant space savings while also improving performance for queries that are executed using indexes. AMD Opteron logo are trademarks or registered trademarks of Advanced Micro Devices. Panels are now incorporated into mobile applications and are used to display navigation menus. In-memory jobs have better performance and scalability. Therefore, it can run into application errors with PL/SQL complaining about type mismatch. 1 Oracle Database 12c Release 2 (12.2) New Features Application Development Availability Big Data and Data Warehousing Compression and Archiving Database Lifecycle Management Database Overall Diagnosability Exadata Manageability Miscellaneous Performance Public Cloud RAC and Grid Security Spatial and Graph Windows The ability to use longer schema object identifier names increases database development flexibility and makes database migration to Oracle Database easier. The following optimizations were implemented: Improved performance for Java andJavaScript stored procedures as well as Oracle Databasecomponents that use For some network errors, SRVM may fail on Microsoft Windows Server 2016. Oracle 12c Free Download Latest Version setup for Windows. adaptation of the programs, including any operating system, integrated software, any Now you have the option of specifying MDATA sections as read-only, which means they can only be changed when the document is updated and the index is synchronized. This feature eliminates the need to create application outages for the purpose of cloning. This feature enables you to specify file system size quotas and have the file system automatically increase in size, if required. Using multiple columns to define the partitioning criteria for list partitioned tables enables new classes of applications to benefit from partitioning. This feature provides significant performance improvements involving parallelism and optimization enabling all algorithms to scale to data volumes found in big data and cloud use cases. This new functionality provides more robust and simplified code development. (Previously known as: Database Cloud Service), Exadata Database Service on Dedicated Infrastructure1, (Previously known as:Exadata Cloud Service), (Previously known as:Exadata Cloud at Customer). The multimedia data can be consolidated with other types of data in the database for easy display in reports and web UIs. This option tells the Data Pump to load partition data in parallel into existing tables. Processing more information about expressions and their usage is useful for establishing better query execution plans. The ability to easily define duration-based events and restyle the calendars, makes the new calendar very popular with both developers and end-users. personal injury. Certain countries require the use of their specific national and government standards for encryption. The ACCESSIBLE BY clause specifies a list of PL/SQL units that are considered safe to invoke the subprogram, and blocks all others. Within a user profile, the INACTIVE_ACCOUNT_TIME parameter controls the maximum time that an account can remain unused. In a multitenant environment, a pluggable database (PDB) lockdown profile is a mechanism used to restrict operations that can be performed by connections to a given PDB for both cloud and non-cloud environments. A database administrator (DBA) can create resource manager plans with the appropriate level of detail for the environment. In Oracle Database 12c Release 2 (12.2), installing Oracle Grid Infrastructure includes the option of deploying Application Cluster, which is a generic form of Oracle Grid Infrastructure that makes applications, including non-Oracle applications, highly available. Developers that want to use the latest Entity Framework Code First features to develop Entity Framework applications can now do so with ODP.NET. This feature helps in the seamless migrations of Oracle Database 12c to Oracle Exadata, thus expanding the Oracle Exadata adoption. Parallel PDB creation speeds up the provisioning of PDBs. Oracle Database 21c is an Innovation release for customers to innovate faster with new and enhanced functionality on workload use cases and applications that could benefit accordingly. Use this tool to find disk errors (such as lost write) that cannot be detected by other tools like the DBVERIFY utility. These common Oracle Database Vault controls protect common objects in all pluggable databases (PDB) where Oracle Database Vault is enabled. This feature provides greater flexibility for Oracle Data Redaction customers. There is a way to enforce common realms and command rules protections across all PDBs by turning on Oracle Database Vault strict mode. The information in the view can be used to determine whether indexes are used and the frequency of usage, and this information can be used to evaluate indexing strategies in the database. This feature enables routing and processing of queries and transactions that access data that isstored on multiple shards. 11.2.0.x) For scheduled maintenance at the database server, Oracle Database 12c Release 2 (12.2) provides: This feature hides scheduled maintenance operations that are required for the underlying infrastructure (Oracle Database, Oracle Grid Infrastructure, operating system, and hardware) without placing a burden on application developers. After the gridSetup.bat -upgrade on all the nodes is complete, launch the installer to run the configuration tools using the following command: This issue is tracked with Oracle bug 22637209. Additional performance enhancements were made for SELECT statements using RAS. Oracle Data Provider for .NET now supports schema object identifier names, such as tables, columns, views, stored procedures, and functions, up to 128 characters in length. Data loading and graph operations are parallelized. The Oracle Recovery Manager (RMAN) table recovery feature offers REMAP TABLE and REMAP TABLESPACE options. 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. Both normal restore points (which are an assignment of a system change number (SCN) to an alias) and guaranteed restore points (which guarantee the database to be flashed back to a point in time) can be performed at the PDB level. This reduces the time to import the table data. In addition to ON COMMIT and ON DEMAND refresh, the materialized join views can be refreshed when a DML operation takes place, without the need to commit such a transaction. TFA encapsulates diagnostic data collection for all clusters and Oracle Database components on all servers into a single command executed on one server only. Recursive WITH type queries are also commonly used in transportation networks (for example, for flight paths, roadways, and so on). These releases have 5 years of Premier Support followed by 3 years of Extended Support. You can now dynamically increase the size of the in-memory area while the database is open, assuming that enough memory is available within the SGA. Users may also need to failover a PDB from a Data Guard Standby database to a new production container database when the production PDB has failed but the container database and all other PDBs function normally. Normal Duplicate Database From Physical Standby Database. The collective abilities of these enhancements make this feature much more robust in its ability to be configured to meet various data protection and availability goals, regardless of the configuration used. It can be used to rename entire tables or to rename table partitions. Application Continuity is an application-independent feature that attempts to recover incomplete requests from an application perspective and masks many system, communication and hardware failures, and storage outages from the user. The default directory is now $ORACLE_BASE_HOME/ctx/log. Security in a database environment is very important. This capability is built on top of Oracle Direct NFS Client using the NFSv4 and NFSv4.1 protocols. This page provides you with the most commonly used Oracle date functions that help you handle date and time data easily and more effectively. The Oracle ACFS file system alerts a waiting application API call, and the application then collects a set of records that identify which files changed and the location of the changes within each file. SQL Plan Management (SPM) leverages a larger pool of plan information (including Automatic Workload Repository (AWR)) as a source for SQL plan baselines. For example, if performance investigation reports the SQL_ID of a slow statement, its call sites in the PL/SQL programs can be found immediately. The active duplicate defaults to backup set method only when the number of auxiliary channels is equal to or greater than the target channels and there is a TNS alias for the target database. Oracle ACFS metadata is stored on the accelerator volume. Where the platform supports it, a 32-bit and 64-bit client is also part of the release. Using resource groups, Oracle Clusterware provides an intuitive model to manage and monitor an application composed of various resources as a single composite entity. 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. Oracle has a global Extended Support Uplift Fee waiver in place for E-Business customers, see details and dates of expiration see: Extended Support Fee Waiver for Oracle Database 12.1 and 11.2 for Oracle E-Business Suite (Doc ID 2522948.1) or Technical Support Policy Document. With this new feature, you can control the SQL execution plans of recursive SQL statements generated from the CONTAINERS () query. There is no reason for scheduled maintenance to be burdensome for application users. This new feature enhances the dNFS Client so that it can support all widely accepted NFS path formats, including both Windows style and UNIX style NFS paths. You cannot directly connect to read-only instances. Employs more complex compression algorithms than advanced low compression. 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. In Oracle Database 12c Release 1 (12.1.0.2), this support is added for Exadata and Exalogic environments. The Oracle ACFS compression project improves both Oracle Database and general purpose file storage. Currently, when a role change occurs and an Active Data Guard standby becomes the primary, all read-only user connections are disconnected and must reconnect, losing their state information. Spatial indexes can now be partitioned based on hash and list mechanisms in addition to the existing support for range partitioning. Support is added for printjoins and skipjoins characters in the JAPANESE_VGRAM_LEXER and WORLD_LEXER types. You no longer need to manually edit a page using JavaScript.
