Advanced Oracle Data Integrator (ODI) Interview Questions & Answers 2. Q. What is Oracle Data Integrator (ODI)? Oracle acquired Sunopsis in 2. Sunopsis Data Integrator”. Oracle Data Integrator (ODI) is an E- LT (Extract, Load and Transform) tool used for high- speed data movement between disparate systems. The latest version, Oracle Data Integrator Enterprise Edition (ODI- EE) brings together “Oracle Data Integrator” and “Oracle Warehouse Builder” as separate components of a single product with a single licence. Q. What is E- LT? ODI interview questions: 1. What is Oracle Data Integrator? 2. Can we call ODI as a ETL tool. If yes then How? 3. Is it a ELT tool? Explain. 4. What are the new.E- LT is an innovative approach to extracting, loading and Transforming data. Typically ETL application vendors have relied on costly heavyweight , mid- tier server to perform the transformations required when moving large volumes of data around the enterprise. ODI delivers unique next- generation, Extract Load and Transform (E- LT) technology that improves performance and reduces data integration costs, even across heterogeneous systems by pushing the processing required down to the typically large and powerful database servers already in place within the enterprise. Q. What components make up Oracle Data Integrator?“Oracle Data Integrator” comprises of: 1) Oracle Data Integrator + Topology Manager + Designer + Operator + Agent. Oracle Data Quality for Data Integrator. Oracle Data Profiling. Working with Tables in Excel 2013, 20 (VBA) This article has also been published on Microsoft Office Online: Working with Excel tables in Visual Basic for. Q. What is Oracle Data Integration Suite? Oracle data integration suite is a set of data management applications for building, deploying, and managing enterprise data integration solutions: 1. Oracle Data Integrator Enterprise Edition. Oracle Data Relationship Management. Oracle Service Bus (limited use)4. Oracle BPEL (limited use)5. Oracle Web. Logic Server (limited use)Additional product options are: 1. Oracle Goldengate. Oracle Data Quality for Oracle Data Integrator (Trillium- based DQ)3. Oracle Data Profiling (Trillium based Data Profiling)4. ODSI (the former Aqualogic Data Services Platform)Q. What systems can ODI extract and load data into? ODI brings true heterogeneous connectivity out- of- the- box, it can connect natively to Oracle, Sybase, MS SQL Server, My. SQL, LDAP, DB2, Postgre. SQL, Netezza. It can also connect to any data source supporting JDBC, its possible even to use the Oracle BI Server as a data source using the jdbc driver that ships with BI Publisher. Q. What are Knowledge Modules? Knowledge Modules form the basis of ‘plug- ins’ that allow ODI to generate the relevant execution code , across technologies , to perform tasks in one of six areas, the six types of knowledge module consist of: Reverse- engineering knowledge modules are used for reading the table and other object metadata from source databases. Journalizing knowledge modules record the new and changed data within either a single table or view or a consistent set of tables or views. Loading knowledge modules are used for efficient extraction of data from source databases for loading into a staging area (database- specific bulk unload utilities can be used where available)Check knowledge modules are used for detecting errors in source data. Integration knowledge modules are used for efficiently transforming data from staging area to the target tables, generating the optimized native SQL for the given database. Service knowledge modules provide the ability to expose data as Web services. ODI ships with many knowledge modules out of the box, these are also extendable, they can modified within the ODI Designer module. Q. How do ‘Contexts’ work in ODI? ODI offers a unique design approach through use of Contexts and Logical schemas. Imagine a development team, within the ODI Topology manager a senior developer can define the system architecture, connections, databases, data servers (tables etc) and so forth. These objects are linked through contexts to ‘logical’ architecture objects that are then used by other developers to simply create interfaces using these logical objects, at run- time, on specification of a context within which to execute the interfaces, ODI will use the correct physical connections, databases + tables (source + target) linked the logical objects being used in those interfaces as defined within the environment Topology. Q. Does my ODI infrastructure require an Oracle database? No, the ODI modular repositories (Master + and one of multiple Work repositories) can be installed on any database engine that supports ANSI ISO 8. Oracle, Microsoft SQL Server, Sybase AS Enterprise, IBM DB2 UDB, IBM DB2/4. Q. Where can I get more information on ODI? The OTN Data integration home page : http: //bit. Myxa. 4JQ. Does ODI support web services? Yes, ODI is ‘SOA’ enabled and its web services can be used in 3 ways: The Oracle Data Integrator Public Web Service, that lets you execute a scenario (a published package) from a web service call. Data Services, which provide a web service over an ODI data store (i. ODI)The ODIInvoke. Web. Service tool that you can add to a package to request a response from a web service. Q. Where does ODI sit with my existing OWB implementation(s)? As mentioned previously, the ODI- EE licence includes both ODI and OWB as separate products, both tools will converge in time into “Oracle’s Unified Data Integration Product”. Oracle have released a statement of direction for both products, published January 2. Myw. Xi. 4OWB 1. 1G R2 is the first step from Oracle to bring these two applications together, its now possible to use ODI Knowledge modules within your OWB 1. G R2 environment as ‘Code Templates’, an Oracle white paper published February 2. Mn. LYNf. Q. What is the ODI Console? ODI console is a web based navigator to access the Designer, Operator and Topology components through browser. Q. Suppose I having 6 interfaces and running the interface 3 rd one failed how to run remaining interfaces? If you are running Sequential load it will stop the other interfaces. If you are running all the interfaces are parallel only one interface will fail and other interfaces will finish. Q. What is load plans and types of load plans? Load plan is a process to run or execute multiple scenarios as a Sequential or parallel or conditional based execution of your scenarios. And same we can call three types of load plans , Sequential, parallel and Condition based load plans. Q. What is profile in ODI? Users will get the privileges from profile. Q. How to write the sub- queries in ODI? Using Yellow interface and sub queries option we can create sub queries in ODI. Using VIEW we can go for sub queries Or Using ODI Procedure we can call direct database queries in ODI. Q. How to remove the duplicate in ODI? Use DISTINCT in IKM level. Q. Suppose having unique and duplicate but i want to load unique record one table and duplicates one table? Create two interfaces or once procedure and use two queries one for Unique values and one for duplicate values. Q. How to implement data validations? Use Filters & Mapping Area AND Data Quality related to constraints use CKM Flowcontrol. Learn all Oracle data integration Course requirements: from high- volume, high- performance batch loads, to event- driven, trickle- feed integration processes. Q. How to handle exceptions? Exceptions In packages advanced tab and load plan exception tab we can handle exceptions. Q. In the package one interface got failed how to know which interface got failed if we no access to operator? Make it mail alert or check into SNP_SESS_LOg tables for session log details. Q. How to implement the logic in procedures if the source side data deleted that will reflect the target side table? User this query on Command on target Delete from Target_table where not exists (Select ‘X’ From Source_table Where Source_table. ID=Target_table. ID). Q. If the Source have total 1. Use IKM Incremental Update Knowledge Module for Both Insert n Update operations. Q. Can we implement package in package? Yes, we can call one package into other package.

Drag and drop both File and table into source area and join as in Staging area. Q. If the source and target are oracle technology tell me the process to achieve this requirement(interfaces, KMS, Models)Use LKM- SQL to SQL or LKM- SQL to Oracle , IKM Oracle Incremental update or Control append. Q. What we specify the in XML data server and parameters for to connect to xml file? File name with location : F and Schema : S this two parameters.
