This document describes the new and enhanced features introduced with Oracle Data Integrator 12c (12.1.2).
Oracle Data Integrator 12c (12.1.2) introduces the following enhancements:
The new declarative flow-based user interface combines the simplicity and ease-of-use of the declarative approach with the flexibility and extensibility of configurable flows. Mappings (the successor of the Interface concept in Oracle Data Integrator 11g) connect sources to targets through a flow of components such as Join, Filter, Aggregate, Set, Split, and so on.
Reusable Mappings can be used to encapsulate flow sections that can then be reused in multiple mappings. A reusable mapping can have input and output signatures to connect to an enclosing flow; it can also contain sources and targets that are encapsulated inside the reusable mapping.
A mapping can now load multiple targets as part of a single flow. The order of target loading can be specified, and the Split component can be optionally used to route rows into different targets, based on one or several conditions.
Mappings, Packages, Procedures, and Scenarios can now be debugged in a step-by-step debugger. Users can manually traverse task execution within these objects and set breakpoints to interrupt execution at pre-defined locations. Values of variables can be introspected and changed during a debugging session, and data of underlying sources and targets can be queried, including the content of uncommitted transactions.
The runtime execution has been improved to enhance performance. Various changes have been made to reduce overhead of session execution, including the introduction of blueprints, which are cached execution plans for sessions. Performance is improved by loading sources in parallel into the staging area. Parallelism of loads can be customized in the physical view of a map. Users also have the option to use unique names for temporary database objects, allowing parallel execution of the same mapping.
The integration of Oracle GoldenGate as a source for the Change Data Capture (CDC) framework has been improved in the following areas:
Oracle GoldenGate source and target systems are now configured as data servers in Topology. Extract and replicate processes are represented by physical and logical schemas. This representation in Topology allows separate configuration of multiple contexts, following the general context philosophy.
Most Oracle GoldenGate parameters can now be added to extract and replicate processes in the physical schema configuration. The UI provides support for selecting parameters from lists. This minimizes the need for the modification of Oracle GoldenGate parameter files after generation.
A single mapping can now be used for journalized CDC load and bulk load of a target. This is enabled by the Oracle GoldenGate JKM using the source model as opposed to the Oracle GoldenGate replication target, as well as configuration of journalizing in mapping as part of a deployment specification. Multiple deployment specifications can be used in a single mapping for journalized load and bulk load.
Oracle GoldenGate parameter files can now be automatically deployed and started to source and target Oracle GoldenGate instances through the JAgent technology.
Oracle Data Integrator standalone agents are now managed through the WebLogic Management Framework. This has the following advantages:
UI-driven configuration through Configuration Wizard
Multiple configurations can be maintained in separate domains
Node Manager can be used to control and automatically restart agents
Oracle Data Integrator can now use the authorization model in Oracle Platform Security Services (OPSS) to control access to resources. Enterprise roles can be mapped into Oracle Data Integrator roles to authorize enterprise users across different tools.
The following XML Schema constructs are now supported:
list and union - List or union-based elements are mapped into VARCHAR columns.
substitutionGroup - Elements based on substitution groups create a table each for all types of the substitution group.
Mixed content - Elements with mixed content map into a VARCHAR column that contains text and markup content of the element.
Annotation - Content of XML schema annotations are stored in the table metadata.
Oracle Warehouse Builder (OWB) jobs can now be executed in Oracle Data Integrator through the
OdiStartOwbJob tool. The OWB repository is configured as a data server in Topology. All the details of the OWB job execution are displayed as a session in the Operator tree. For more information about this feature, see "OdiStartOwbJob".
Master and Work Repositories now use unique IDs following the GUID convention. This avoids collisions during import of artifacts and allows for easier management and consolidation of multiple repositories in an organization.
ODI 12c supports an easier mapping between Oracle Warehouse Builder 11gR2 (18.104.22.168) concepts and objects and their ODI 12c (12.1.2) counterparts. A migration utility is provided that automatically translates many OWB objects and mappings into their ODI equivalents.
The migration utility requires ODI patch 17053768 and the ODI 22.214.171.124.1 bundle patch (patch number 17836908), and OWB patch 17830453. For more information about the migration utility, see Migrating from Oracle Warehouse Builder to Oracle Data Integrator.
