oracle database 12c release 2

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. The remote database should be in archivelog mode. That meant that after a database restart, the In-Memory Column Store would have to be populated from scratch using a multiple step process that converts traditional row formatted data into the compressed columnar format and placed in-memory. With these administrative privileges in place, customers have a choice to implement separation of duty in their environment in a manner that fits their business needs. Description:-This is the article which will guide you step-by-step Duplicating a Database Using RMAN in Oracle Database 12c Release 2. This feature provides a cost-effective way to significantly reduce the disk storage required in a variety of customer environments which use Oracle ACFS files. The problem with the current file format is that the first two blocks of the file have to be updated after the rest of the file is written. The collection of shards is presented to an application as a single logical Oracle database. The accelerator feature significantly improves file access performance for Oracle ACFS files that are stored on the Oracle ACFS primary file system or an Oracle ACFS snapshot. A SQL boolean is of type NUMBER where as PL/SQL boolean is a true BOOLEAN much like in Java. You can now filter statistics on Oracle ZFS Storage Appliance (ZFSSA) based on database IDs (DBID) and pluggable database IDs (PDBID). Data Pump normally moves table data in a network import by using the INSERT AS SELECT SQL statement. Additional performance enhancements were made for SELECT statements using RAS. Approximate query aggregation can be used to speed up existing processing. 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. Online redefinition can restart from most points of failure, eliminating the need to redo the entire operation. LogMiner supports such a primary database. Only a physical standby database can be created when connected to a physical standby database as the target database. The new RESTORE+RECOVER command for data file, tablespace and database performs restore and recovery in one step versus having to issue offline, restore, recover, and online operations. The CDB administrator can then create CDB plan directives for all gold, silver or bronze PDBs using the PL/SQL procedure DBMS_RESOURCE_MANAGER.CREATE_CDB_PROFILE_DIRECTIVE(). The collection of shards is presented to an application as a single logical Oracle database. The multimedia data can be consolidated with other types of data in the database for easy display in reports and web UIs. 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. Without this feature, data scientists would need to build and manage hundreds or thousands of models to achieve this functionality, resulting in significant usability and performance issues. While similar to the diagnostic collection feature, the Oracle Trace File Analyzer (TFA) Collector allows centralization and automatic collection of diagnostic information. The user in the local database must have the CREATE PLUGGABLE DATABASEprivilege in the root container. It is also an Open Geospatial Consortium (OGC) compliant Web Map Service (WMS) and Web Map Tile Service (WMTS) server. Read-only workloads may be load-balanced across all copies of shards used for HA for additional scalability when using Oracle Active Data Guard. 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 feature introduces new SQL*Plus commands SET PREFETCH, SET LOBPREFETCH, and SET STATEMENTCACHE. 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. Techniques such as greedy search, pruning of unpromising intermediate paths, and bi-directional searches are implemented to optimize performance. For instance, business applications such as Field Service, Transportation and Logistics, Asset Lifecycle Management, Human Resources, and Real Estate can now render and visualize the massive amount of data they control if there is a geographic component such as an address tied to the data. To enhance planned outage functionality for an Oracle Data Guard switchover and Oracle Real Application Clusters One Node, new connection requests are paused until the transition to the new instance occurs. There is a way to enforce common realms and command rules protections across all PDBs by turning on Oracle Database Vault strict mode. This property gets the value, in seconds, of the SecondsToTrustIdleConnection()property. The information contained herein is subject to change without notice Following very simple configuration and operational practices, you can completely hide the adverse effects of scheduled maintenance from all application types. A shard topology cache is used to route the connection directly to the shard where the data resides. 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. A join group allows the user to specify which columns are used for joins across tables so those columns can always be compressed using the same encoding techniques. Physical database replication provides the strongest data protection using real time Oracle data validation. The Oracle Database 12c is a high-performance, enterprise-class database. Without this you must open the remote PDB or non-CDB in read-only mode. You can now specify when one or more jobs cannot execute at the same time. The new file format enables OLH to run faster since it no longer needs to write file data multiple times to avoid updating the first two header blocks in the file. In a high availability (HA) configuration, the database tier can tolerate a planned outage by offering services on a different instance or a standby replica. Administrators now have the flexibility to use their preferred NFS path format. In Oracle Database 12c Release 1 (12.1), Oracle Recovery Manager introduced cross-platform transport capability. This makes operations such as transportable tablespace and exchange partition more efficient. This feature is required for managing CDBs that have many pluggable databases in a public cloud context. This enables you to limit the file system expansions and to prevent runaway storage consumption. The ALL_GLOBAL_DBLINKS initialization parameter specifies whether LDAP lookup for database links are allowed for the database. Go to Oracle Client 12c and select the Oracle version that corresponds to your operating system (32-bit or 64-bit). Application developers were required to deal explicitly with outages of the underlying software, hardware, and communications layers if they wanted to mask outages from users. In Oracle Database 12c Release 1 (12.1), the default tablespace was allowed when creating a pluggable database (PDB) using the seed PDB. This feature enables the consolidation of databases that have different character sets, time zone file versions, and database time zones into a CDB. This feature also enables routing for queries that do not specify a shard key. Oracle Application Express Universal Theme provides a number of new capabilities including Theme Roller, Template Options, responsive design, and accessibility. The new calendar component includes built-in support for Month, Week, Day, and Agenda views, and is much easier to customize. For multitenant container databases (CDBs) with thousands of pluggable databases (PDBs), it is cumbersome to configure memory and other Resource Manager directives. A resource can be anything specified by the user and only has two attributes, name and count. 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. If there is a problem during the upgrade, then the database can be quickly restarted by restoring the copies of the system tablespaces and opening the database in the original (old) Oracle home. 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. Database views can manage and display details about Oracle GoldenGate conflict resolution methods, including DBA_APPLY_REPERROR_HANDLERS, DBA_APPLY_HANDLECOLLISIONS, DBA_APPLY_DML_CONF_HANDLERS, and DBA_APPLY_DML_CONF_COLUMNS. Basically, when a data file is lost on a primary or standby database, RMAN generates repair scripts to fetch the file from the primary or standby database. In both cases, the primary database continues on, remaining in its zero data loss protection mode because one synchronous standby database has acknowledged receipt of the redo. Oracle Application Express release 5.0 mobile improvements enable the development of improved mobile-first applications. This functionality is similar to the shell history command available on the UNIX platform command line shells. Until now, the columnar format has only been available in-memory. It is also possible to populate a completely different set of data in the in-memory column store on the primary and standby databases, effectively doubling the size of the in-memory column store that is available to the application. ADO support has now been extended to encompass the In-Memory Column Store. Oracle sharding supports automated deployment, high performance routing, and complete life-cycle management. It provides greater flexibility to designate rules that define priority, and it provides numerous options for defining policies in a failure state. SYSRAC comes after the introduction of SYSKM, SYSDG, and SYSBACKUP in Oracle Database 12c Release 1 (12.1) to provide separation of duty for key management, Oracle Data Guard and RMAN backup, respectively. Using the correct setup, no errors are reported for either new, incoming work, or for existing work while maintenance is in progress. With this new feature, a you can choose to create a single PDB archive file, a compressed file with the .pdb extension, that contains the PDB manifest and all of the data files when unplugging a PDB. Collation (also called sort ordering) determines if a character string equals, precedes or follows another string when the two strings are compared and sorted. The location of the XML file is specified either in the system property or in the setXMLConfigFile() API. The remote CDB must use local undo mode. A much finer degree of data management is possible through this new feature in addition to the SELECT performance enhancements. Understand the new and enhanced features of Oracle Database 12c Release 2 ( amongst different areas such as the new Multitenant architecture and the Sharded database architecture. It is easier to fully control your application user interface. Oracle Database 12c Release 2 (12.2) provides two types of instances within the same database: read/write and read-only. SQL profile recommendations implemented on the primary database are applied to the Active Data Guard standby using the redo apply mechanism. A new data guide feature that facilitates understanding of the structure and content of your JSON documents. 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. 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. This made the discussion of garbage collection (the dropping of editioned objects in retired editions that were not the source of inherited representation in non-retired editions (hereinafter covered objects)) difficult. Examples of this metadata include the Oracle ACFS volume log, indirect nodes, also known as extent nodes, space management structures, and other Oracle ACFS metadata. Oracle Data Pump jobs now take less time because parallel import of metadata is added to this release. This feature provides enhanced security when interacting with the operating system from a PDB. With this feature, the processing of large volumes of data is significantly faster than the exact aggregation. 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. At execution time, Oracle Scheduler ensures that running jobs are not going to exceed the available resources. Currently, it is not possible to create a copy of a database when the target database is a physical standby database. This is done by capturing and replaying the top level PL/SQL calls. A suite of application programming interfaces (APIs) that allow programmable access to the map visualization features. This feature addresses three capabilities of Oracle Recovery Manager (RMAN) in a cross-platform migration: Transporting the data across platforms helps in migration, ease of use, and more adoption of Oracle databases. Hybrid Columnar Compression (HCC) can now be used during array inserts into tables. A shard topology cache in the connection layer is used to route the request directly to the shard where the data resides. This feature streamlines the application of additional controls such as encryption and auditing to sensitive data stored inside applications. This new parameter is global for all synchronous standby database destinations and defines the maximum amount of time (in seconds) that the primary database must wait before disconnecting subsequent destinations after at least one synchronous standby database has acknowledged receipt of the redo. This feature addresses: This feature increases customer adoption of consolidating their databases deployed with different architecture into the multitenant database architecture. They are also able to start making use of the feature set of XQuery 3.0. This feature adds more flexibility to import or recover tables across different schemas, which provides more freedom to users and may also provide a better understanding of table-related indexes, triggers, constraints, and so on, if these object names are already existing under the same schema. You specify the tag that delimits the smaller document as part of the access parameters. This feature also enables parallel loading of XML Data with partitioning and XMLIndex support for inter- and intra-partition parallelism. 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). This feature greatly expands the number of alternate destinations that you can define. Users can configure Oracle Universal Connection Pool (UCP) using XML to specify pool properties, such as minPoolSize and maxPoolSize. Enhancements to Oracle Spatial and Graph GeoRaster allow the use of an unlimited number of image layers (sets of imagery, sets of sensor readings, multi- and hyper-spectral data) when performing analysis and processing operations. However, neither FAN nor earlier Oracle Database technology reported the outcome of the last transaction to the application or recovered the in-progress request from an application perspective. Home » Articles » 12c » Here. agreement containing restrictions on use and disclosure and are protected by DBMS_STATS now supports external table scan rates and In-Memory Column Store (IM column store) statistics. This usually follows a restore operation. 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. Now you can easily define modal and non-modal pages, complete with the ability to use standard page processes. Oracle Database support multiple operating systems like Redhat, SUSE, Oracle Linux, Microsoft Windows and IBM Linux. The AL32UTF8 character set is Oracle Corporation's implementation of the industry standard UTF-8 encoding which supports all of the written languages of the world. This is achieved by writing brief information describing the representation of empty blocks on the storage device instead of the actual insertion of zeros into empty (unwritten) but allocated space on the storage device. Previous functionality allowed for only a single fast-start failover target. With ODP.NET, Managed and Unmanaged Drivers can be deployed easily to common hosted and third-party cloud environments through Web deploy. Today, Oracle is proud to announce the general availability of Oracle Database 12c Release 2, the latest version of the #1 database in the industry for on-premises customers. For tables that contain data types that cannot be moved with OCIDirPath, the Data Pump continues to use INSERT AS SELECT. The sparse file approach reduces the overhead for the time required to create an image file because there is no requirement to allocate and zero fill unused file storage. Using the operating system that is described by a credential (refer to DBMS_CREDENTIAL on how to create operating system user credentials) whose name is specified as a value of the PDB_OS_CREDENTIAL parameter, ensures that operating system interactions are performed as a less powerful user. In previous releases, the maximum length of a SQL identifier or a database schema object name was 31 characters, and all characters must be legal and convertible to the target database character set. Cloning of a pluggable database (PDB) resolves the issue of setting the source system to read-only mode before creating a full or snapshot clone of a PDB. You can choose to run the PDB plug-in compatibility test directly on the PDB archive without extracting the PDB manifest file from the archive. October 2020. PL/SQL developers can now use this standard quality metric. Logical standby databases support such a primary database. A typical use case is credit card or financial securities validation. This feature improves the efficiency of client-side encoding and decoding of binary XML by reducing the changes of the tokens that need to be reloaded during encoding and decoding operations. For repeating in-memory jobs, job metadata is written to disk but there is no run information. Stores data in a compression unit, which is a special on-disk format. Scaling apply performance in this manner means that the standby database is always up-to-date even at very high volumes on the largest Oracle RAC clusters. Oracle Application Express release 5.0 includes a broad collection of point solutions called packaged applications. In this release, support for operations over database links for LOB-based data types, such as CLOB, BLOB and XMLType, is available. Creating a table that qualifies for a partition or subpartition exchange can be a tedious task for older tables that have had various structural changes and reorganizations. For cases where it is possible, the Data Pump uses OCIDirPathUnload to unload the data from the remote database and then uses OCIDirPathLoad to load the table data into the target database. Users with more than one synchronous standby database destination can reduce the impact of transient network failures by allowing the primary database to continue as long as one synchronous standby database has all the redo. This extends the usability of DBFS to include applications that use file locks to coordinate application behavior across multiple connections or users. Oracle Loader for Hadoop (OLH) uses files that are written and read by the ORACLE_DATAPUMP access driver. 2. If this is software or related documentation that is delivered to the Sharding with Oracle Database 12c Release 2 (12.2) provides a number of benefits: Java Database Connectivity (JDBC), Oracle Call Interface (OCI), and Oracle Data Provider for .NET (ODP.NET) clients are able to recognize shard keys specified in a connection string. These advantages enable the rapid development and deployment of In-Memory databases and other applications that include multimedia data. With this feature, you can now adjust to changing workloads and comply with Service Level Agreement (SLA) requirements in near real time. It also eliminates an obstacle to consolidating to a few databases due to too many connection pools and connections serving these tenants. Oracle Enterprise Manager Database Express (EM Express) is enhanced for multitenant container database (CDB) to support a single port or URL that is used to access any of the pluggable databases (PDBs) within the CDB. The Oracle Data Guard broker DGMGRL command-line interface allows you to configure and manage on which instances in an Oracle RAC standby the apply processes should be executed to use the new Oracle Active Data Guard multiple instance Redo Apply feature. This feature enables command scripts to be executed through the Oracle Data Guard broker DGMGRL command-line interface; much like in SQL*Plus. Combining RAS implicit data realms with the Oracle Label Security explicit data labeled security provides strong security capabilities to allow formerly separate databases to consolidate into a single database and yet retain the separation of data that was available before the consolidation. The In-Memory Column Store allows objects (tables, partitions, and subpartitions) to be populated in memory in a compressed columnar format. This means that the SQL INSERT SELECT statement without the APPEND hint can use HCC, and array inserts from programmatic interfaces such as PL/SQL and the Oracle Call Interface (OCI) can use HCC. Using this feature requires downtime, because you must take the tablespace temporarily offline. Creating Pluggable Database (PDB) in DBCA Method: The DBCA includes a new option on the opening “Database Operation” screen that allows you to manage the pluggable databases of an existing container database. Database-specific drill down capability is added to ZFS analytics. 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. If the results of a redefinition are not acceptable (for example, a performance slow down accessing a newly redefined table), then the redefinition changes can be easily rolled back, therefore saving the DBA time in performing another redefinition to undo the table changes. 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. New syntax is added to let users specify new file names, or file name transforms, for the data files in a transportable tablespace job. The new database parameter, DB_PERFORMANCE_PROFILE, can be used to specify a class of database or pluggable database (for example, gold, silver, or bronze). Oracle Flex ASM disk groups enable a greater level of consolidation, which enhances the need for prioritization of certain database operations. , 2-Day DBA, Oracle Database 12cR2 , This feature provides a PL/SQL callback facility to enable applications to fix up the state in the Database Resident Connection Pooling (DRCP) pooled servers to the desired state. Since Oracle Database 11g Release 2 (, Oracle Database has supported installations on ReFS. This creates enormous potential for understanding and capturing the geographic components of any business, by unlocking the enterprise information in many corporate warehouses and making it available to basic mapping applications. The new V$ONLINE_REDEF view displays runtime information related to the current redefinition procedure being executed based on a redefinition session identifier. Real-time database operations (DBOP) monitoring functionality has been significantly enhanced as follows: These DBOP enhancements increase DBA efficiency by aligning business operations monitoring with end-user needs, resulting in better quality of service for business applications. Oracle Trace File Analyzer (TFA) collects diagnostic data that can either be analyzed directly or serve as a data stream to auxiliary systems, such as Oracle Support Services, to be visualized or analyzed in a certain context. and is not warranted to be error-free. This feature addresses support for encrypted tablespaces which are also to be migrated using cross-platform transport. A fine-grained information about which indexes are used and how frequently they are used allows you to eliminate infrequently used indexes. You can specify the limit as either I/O requests per second or as Mbps (megabytes of I/O per second). Compile PL/SQL packages, procedures, and functions in addition to the current capability of capturing execution privileges. 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. STS capture support is provided for reporting workloads that are running on standby or an active Oracle Data Guard database. With the addition of XA support, WebLogic Server and others can more easily provide replay with idempotence enforced using Transaction Guard. Third party applications and Oracle Fusion Middleware are an example of target consumers of this library. Security in a database environment is very important. This feature reduces contention on the $R table when many processes are updating rows at the same time. The TFA web-based visualization feature is installed as part of Oracle Grid Infrastructure. Oracle Database Vault simulation mode protection allows customers to test their Oracle Database Vault realms and command rules protections using soft enforcement. 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. In both cases, the data files for the PDB being moved must reside on storage that is visible to the current container database and the target container database. In addition, other coverages published on the Web using this WCS standard can be easily discovered and incorporated into Oracle Spatial and Graph applications. Lower management overhead is now possible because a database administrator (DBA) can upgrade a CDB with multiple PDBs in a single operation. The conversion has no impact on the ongoing DML operations. When failures do occur, they are generally masked from the user. Obtain the Web Services Description Language (WSDL) of a published Web service server furnished as a parameter.
