100 TOP OBIEE scenario based interviewQuestions and Answers iqapdf OBIEE Interview Questions September 12, 2016 1 Comment OBIEE Interview Questions and Answers :- 1. What is OBIEE? Obiee is a ‘Oracle Business Intelligence Enterprise Edition’ and it is a tool which is used to develop enterprise wide reports. So, in simple words it is a report generation tool such as crystal reports. OBIEE is previous called as Seibel Analytic tool before it is acquired by Oracle that now it is called OBIEE tool. 2. What is the meaning behind OBIEE? The initials come from Oracle Business intelligence Enterprise Edition which is a package of BI products. 3. What Business Intelligence (BI) means by definition? It is a protocol and a technique to analyze and report about the state of the business data at a particular time. OBIEE Interview Questions and Answers 4. What types of variable we find in OBIIE? Two types exist and these are the repository variables and session variables. The first kind remains the same anytime and gives birth to other two types: static and dynamic. The static variable changes only when the Siebel Analytics Server administrator wants to make a change. The dynamic variable updates every time a query is executed by a schedule from the Siebel Analytics Server. The second type (session variables) received a new value every time a user is logging on and this second type also splits into other two subtypes: system and non system. Can we tell the difference between a system and a non system variable? Yes. How can the management of the cache made? It could split in three distinct ways: in the first case we can disable the cache of the server by setting a parameter to NO from the NQConfig. The Ragged hierarchy comes into place when we have two different . Is it possible to make new logical columns for BMM layer? Yes it is possible and we can see this example: we can right dick on fact table and we will find here the command to make new logical column and we can name it. 11. It is used as a transition layer to the final result. columns of the original tables. 6. What is the difference between ITS (Logical Table Source) and multiple LTS? In the majority of our time we will deal with multiple LTS which means that multiple physical layer tables are using data instead of a single layer table that is the conditions for single LTS. How can we describe the implicit fact column? We can define it as a joining or combination of data or columns from various tables. 9. pages reports and dashboards that exist in the Siebel Analytics Web Catalog. In this way the queries will be able to use the cache and update it. Provinces/States/ and Cities all defined as levels. 12. On the other hand non system variables or non system session variables can be used as a filter for users. What is Object Level Security? The Object Level Security is to protect the things like folder. In the second case we can adjust the cache at every physical table from the general settings where we will find the “Make cacheable” option. 13. What is the meaning of LBM? LBM is Level Based Metrics meaning how measure is classified in terms of dimension. 8.INI file and then a restart of the server. 15. This method will stop the queries from updating or using the cache. 7. countries. Each user may see a different report according to the access that they have in the company. How can we use the Query Repository tool? With this tool we can search and analyze the name and type or other descriptions from a database. 10. How to handle ragged hierarchy? It is similar to a geographic hierarchy with Continents. dynamic repository or non system session variables. for example system variables are those session variables used by Siebel Analytics Web and Sever and they we can’t use them for static variables. What does Data Level Security in OBIEE? Its role is the control of data type and amount seen in a report. In the third case event polling data table is used to keep an eye of the updates made on each table.5. What is the definition and use of Alias tables? The duplicated made for the tables of a database are called Alias tables and they are links to the properties like rows. 14. What are different types of joins that are possible in OBIEE RPD? 1. pager. The second model is a ragged hierarchy. 2) Table. we must arrive in the Administration tab and click Manage Sessions. 24.B_WID 2. How can we log on as administrators in Siebel? A dialog box from the Manage area of the admin tool can allow us to setup different user ID’s.we can fetch many metrics across various facts. 16. 3) Database. Complex Join –it uses multiple conditions. Prompts b.models. 19. 4) Flexibility and good integration with every data. How one can know what report corresponds to a given table? In order to discover this. Natural Join 23.It have two folders a.every physical table can be restricted. Reports . because in that case the chosen Country does not support Provinces or States. but the join should be of same level of data detail.or Lightweight Directory Access Protocol it provides access limits for various folders or directories.ROW_WID AND / OR A. How we can have two different columns from two different tables or subject areas? Using confirmed dimensions. How can we use saved filters and where we will save the filters? Shared Folders-XYZ Folder. 3) Good infrastructure and Unified Business model. What benefits brings OBIEE usage? 1) It brings an excellent interactive. From there if we select a user we can see that we can modify the level and save it. used to arrange reports to be sent across many devices such as email. Is it possible that for a single dimension logical table to have multiple dimensional hierarchy? Once we right click a logical table and make a new dimensional hierarchy it’s not possible to make another one from the same table so for every dimension logical table we will have only one hierarchy. other devices etc 22. What is ibot? Ibot is an arrangement agent. after we run the report.This can give total or partial access to the database by a user and a password to the user or can restrict all the access. 20. 17. 21. one with a Provence and one without. 4) LDAP. 2) Increases in the insight of each individual by the role in the company. 5) High performance.ROW_WID = B. How different levels of access authentication are classified? The levels are in number of four and their role is to block access to various databases or tables: 1) Operating level. mobile. complex SI functionality and environment.A_WID = B.without this authentication no one can get access in the application as this is the highest level of restriction. such as A. 18. simplifies this join and removes unnecessary columns from the fact table. Siebel repository is a file system . 31. Testing and QA. Siebel analytics server o Metadata represents the analytical Model which is created using the siebel Analytics Administration tool. resulting in a smaller-sized fact table. all the rules needed for security. Clients 2. 6. 27. 4. Explain the end to end life cycle of Siebel Analytics? Siebel Analytics life cycle 1. Build a repository 5. 8. and connectivity is stored in metadata repositories. If we have 3 facts and 4 dimension and we need to join would you recommend joining fact with fact? If no than what is the option? In the BMM layer. What is connection pool and how many connection pools did we have in our last project? . Siebel Analytics Server can access many repositories. 30. usually a number. 28. Siebel analytics scheduler 5. rpd. There are five parts of Siebel Architecture. in the level aggregate table. Repository stores the Meta data information. META DATA REPOSITORY 2. Define surrogate key. rendered in Siebel answer. Define repository in terms of Siebel Analytics. Define security 7.Every metadata repository can store many business models. A surrogate key is an artificially generated key. we can stop a exact report placed on the dashboard. aggregate navigation. Collect Business Requirements 2.extension of the repository file. data modeling.With Siebel Analytics Server. Siebel analytics Web Server data sorces 4. Based on performance. Plan ETL to load to a DW if source data doesn’t exist. A surrogate key. Have you worked in dashboard? when we run a dashboard? how will we stop the dashboard report run automatically? By clicking on the cancel button. caching. Recognize source systems 3. decide an aggregations and/or caching mechanism. Business – copies the Data sources into Facts And Dimension 3. 1. 3.we can create one logical table (fact) and add the 3 fact table as logical table source. data sorces 3. o Repository divided into three layer 1. Physical – Signifies the data Sources 2. How does Siebel Architecture works? Explain the three layers. 29.25. Presentation – Specifies the users view of the model . 1. 26. Build dashboard or use answers for reporting. How we can split a table in the rpd given the condition. We have to make a dubbed table in the physical layer. we can have multiple data sources in Siebel Analytics. No we cant migrate the presentation layer to a different server rather we have to migrate the whole web & rpd files 35. and run Java applets. How we can identify the dimension tables and how we can decide them during the Business/Data modeling? Dimension tables contain descriptions about data analysts which is used as query in the database. Can we have multiple data sources in Siebel Analytics? Yes. it is just a repository file which is known as Rapidfile Database. 33.. How we can disable cache for only 2 particular tables? We can disable cache in the physical layer. not the database itself. ( the condition given was Broker and customer in the same table) Split Broker and customer. What type of protocol did we use in SAS? TCP/IP type protocol. Can we migrate the presentation layer to a different server. 38. Oracle doesn’t recommend Opaque Views because of performance considerations. end . 37. An opaque view should be used only if there is no other option. Define JDK and why do we need it? Java Development Kit (JDK). 41.: connection pool is needed for each and every physical database. so why/when do we use them? An opaque view is a physical layer table that contain select statement. compile. debug. . 34. Why do we have multiple LTS in BMM layer?What is the purpose? To improve the performance and query response time we have multiple LTS in BMM. 42. –> It contains material about the connection to the database. How we can deal with case statement and expressions in siebel analytics? By using expression builder we can create case statement when…then. 40. each row in a table is uniquely identified by its primary-key value or values 36. –> We can use either shared user accounts or pass-through accounts -Use: USER and PASSWORD for pass through We can have many connection pools for each group to avoid waiting 32. Every table contains a primary key that contains one or more columns. is a software package that contains the minimal set of tools needed to write. by right clicking on the table there we can have the option which define cacheable 39. What is the full form of rpd? There is no full form for rpd as such. A combination of business logic security. Users can add sub-folders to their personal folders to organize their content in the way that is the most logical to them.43. The objects in a personal folder can be accessed only by the user who created and saved the content into that folder. Users have their own personal folder (My Folders). instanceconfig.catalog object security.ini.ini are the 2 places 46.ini. Give a brief introduction of OBIEE? Oracle BI Enterprise Edition (sometimes simply referred to as Oracle Business Intelligence) provides a full range of business intelligence capabilities that allow you to: • Collect up-to-date data from your organization • Present the data in easy-to-understand formats (such as tables and graphs) • Deliver data in a timely fashion to the employees in your organization 52. Explain query repository tool? –> It is utility of OBIEE /Seibel Admin tool –> allows us to examine the repository metadata tool –> It Examine relationship between metadata objects like which column in the presentation layer maps to which table in physical layer –> for example: search for objects based on name.xml and nqsconfig.Define pipeline. What are the Key Configuration Files in OBIEE? The key configuration files in OBIEE 11g are NQSConfig. and data level security determines who has the ability to view data and objects. comlex join. and KPIs. dashboards. 45. 48. economics etc. Pipelines are the stages in a particular contract. 44.type.level base matrics. Where we can add new groups and set permissions? Explain what is R? We can add groups by going to manage>security>add new groups> We can give permissions to a group for query limitation and filter conditions.xml 51. time series wizard. where they can store the objects that they create. that you and other users create using Oracle BI EE. such as analyses. What do you know about Initialization Blocks? –> Init blocks are used for instantiating a session when a user logs in. edit objects. 47.ini. valuation. What are the things we can do in the BMM layer? We can do Aggrigation navigation . Where are passwords for userid? Passwords for userid are in siebel analytics server repository . 50. How can you bypass siebel analytics server security ? It can by-passed by setting authententication type in NQSCONFIG file in the security section as:authentication_type=bypass_nqs.instanceconfig. What Is the Oracle BI Presentation Catalog? The Oracle BI Presentation Catalog stores the objects. and delete . NQSCluster. 49. odbc. –> To make dynamic variable we have to create IB to write sql statement. create new logical column. You can also store objects in shared folders where other users or groups can access the objects. rather than to the Oracle BI Server 55. Oracle WebLogic Server replaces Oracle Application Server and Oracle Containers for Java (OC4J). 54.With OBIEE Server. Each metadata repository can store multiple business models. you can drill down to the city level within a sales report. It can perform software installation and configuration steps in the same process or separately in their own processes This release add the following administration command-line utilities: Oracle WebLogic Server scripting tool (WLST) for managing the Oracle WebLogic Server domain. you can then drill down on the pending sale and go directly to that opportunity in the Oracle BI application. the default ODBC DSN for the Oracle BI Server points to the Cluster Controller by default. OPMN and the opmnctl commands for the Oracle Process Manager and Notification Server. aggregate navigation. What is OBIEE 11G? Oracle Business Intelligence Enterprise Edition (OBIEE) 11g is the most significant release of OBIEE since 2006. if you work in sales.rpd”. and connectivity is stored in metadata repositories. Because of this. • Security in Oracle BI: OBIEE allows a high degree of control over access to elements in Oracle BI applications. 56. caching. Oracle Business Intelligence is now deployed in a clustered configuration by default. 53. OBIEE Server can access multiple repositories . all the rules needed for security. Explain the main features of OBIEE 11G? Oracle Business Intelligence is now more integrate with the Oracle Fusion Middleware software family. Oracle BI applications are integrated with operational applications to provide business metrics in reports. Presentation Catalog object security and Data level security. A database repository must be created before installation of the components with the Repository Creation Utility (RCU) tool Log centralization via the web log viewer In addition. and load data into the Oracle Business Analytics Warehouse. The security mechanism comprises Business logic object security. Define repository in terms of OBIEE? Repository stores the Meta data information. in context with an organization’s business function and industry. If you are using an Oracle Siebel operational application. • Drilling Down in Oracle BI: In OBIEE.objects from the catalog. industry-specific Oracl e BI interactive dashboards and Oracle BI reports that are built using industry best practices and address key functional areas within an organization. and observe that there is a large sale pending in Paris.The extension of the repository file is “. Oracle BI applications include Extract Transform Load (ETL) routines to extract. transform. Your administrator creates and maintains the catalog’s shared folder structure. Oracle Business Intelligence 11g Installer replaces the installer that was used in previous versions of Oracle Business Intelligence. For example.data modeling. Explain Oracle Business Intelligence Applications? An Oracle BI application consists of pre-built. you can drill down from a dashboard or report to an actual item in the database. A logical table source shows how the logical objects are mapped to the physical layer and can be mapped to physical tables. What is Authentication? How many types of authentication do we have in OBIEE? Authentication is the process by which a system verifies a user with the help of a user ID and password. • Testing and QA. Ex: If you observe that most of the queries are fired on aggregated values like yearly or monthly data rather that day level data then to speed up the report we can create an aggregate table containing month level and year level data and map it to the respective logical table and set the aggregation levels in the content tab of LTS.Repository is divided into three layer. Using aggregate tables is a very popular technique for speeding up query response times in decision support systems. names. Alias Tables can be an important part of designing a physical layer. 58. What is aggregate navigation? How do you configure the Aggregate tables in OBIEE? Aggregate tables store pre-computed results. 59. . which are measures that have been aggregated (typically summed) over a set of dimensional attributes. or joins • To help you design sophisticated star or snowflake structures in the business model layer. decide on aggregations and/or caching mechanism. stored procedures and select statements. • Physical – Represents the data Sources • Business – model the Data sources into Facts and Dimension and apply business logic • Presentation – Specifies the user’s view of the data rendered in OBIEE answers client 57. What is the purpose of Alias Tables? An Alias table is a physical table with the type of Alias. There are 4 main types of Authentication in OBIEE: • Operating system authentication • External table authentication • Database authentication • LDAP authentication 60. It is a reference to a physical table. each with different keys. It checks if user has the necessary permissions and authorizations to log in and access data. The following is a list of the main reasons to create an alias table: • To reuse an existing table more than once in your physical layer (without having to import it several times) • To set up multiple alias tables. What is the end to end life cycle of OBIEE? OBIEE life cycle: • Gather Business Requirements • Identify source systems • Design ETL to load data to the Data Warehouse • Build a repository • Build dashboards and reports • Define security (LDAP or External table) • Based on performance. Alias tables are critical in the process of converting ER Schems to Dimensional Sachems. An alias table can be a reference to any of these logical table source types. and inherits all its column definitions and some properties from the physical table. What kind of sources can be connected to OBIee? OBIee can be plugged on Relational Databases.Oracle BI Server: The user constructs sql and passes it to the Analytic Engine and then the Oracle BI (Analytic Engine) describes the physical sql to the Datasources and recover the data back to the Engine and presents to the presentation Services . the initialization of session variables is not scheduled. d. Cubes or Flat files. How we can extract sql from OBIEE for reports? There are many ways to extract the sql: a. c. 66. The Oracle BI Server substitutes the value of the repository variable for the variable itself in the metadata. Unlike dynamic repository variables. Difference between a session and repo variable? Session variables are similar to dynamic repository variables in that they obtain their values from initialization blocks. 64. Change the request and click Advanced in that you get xml code and also the actual sql. then go to the NQQuery. Explain the Architecture of OBIEE 11g and function of each components? OBIEE Comprises Presentation Services. Repository variables can be used instead of literals or constants in Expression Builder in the Administration Tool. • In case of multiple sources directly in OBIee used together. the Oracle BI Server creates new instances of session variables and initializes them. Each instance of a session variable could be initialized to a different value. and OBIee is not a database. however. When a user begins a session. 63. Enable Loglevel to 2 in the OBIEE 11g Administration Tool from Manage-> Security and enable the log level to 2 by clicking properties for the user. In the Create Report Window –> Click Request SQL and save the sql to the physical path in your PC. 62. In the catalog Manager click Tools-Create Report .You will find the SQL for that User. 67. 65. How we can do different types of narrative Reports in OBIEE? By clicking modify request and Narrative View and by giving @1 for the first column result and @2 for the 2nd column and so on and we can also give a heading for No Results by clicking the Narrative view. By clcking Administration->Manage sessions-> view sql. Unlike a repository variable.log in BI_HOME/OracleBI/Server/Logs. with the following constraints : • The sources must be modeled as star schemas or snowflakes schemas in order to have an efficient and safe behavior. How will you create Interactive Dashboards ? By clicking on Administration and Manage dashboards and by adding column selector we can create interactive Dashboard. b. . there are as many instances of a session variable as there are active sessions on the Oracle BI Server. A repository variable has a single value at any point in time. be aware that OBIee will conduct the needed joins itself.61. How can you sort in Reports in OBIEE 11g? Click on modify and then click on sort (order by icon) on the relevant column in the criteria pane. By this we can create report from two subject areas. Have you created Hierarchy in OBIEE 11g. we can create hierarchy in BMM Layer of OBIEE in dimensions for the dimension tables. .then it will be visible to all users. Repository variable: This variable is used for the whole repository. How will you go about adding additional column to the repository in the presentation layer? Check if the table is already existing if so add in physical layer . 69. Table alias can be created by right clicking the table in the physical layer then click alias. System variable uses NQ_SESSION. reports. How will you execute Direct SQL in OBIEE? By clicking Direct Database Request below the subject area in we can execute Direct SQL in OBIEE. 71.then click on BMM and then Presentation layer. What are the different types of variables in OBIEE 11g? explain There are two types of variables in OBIEE 11g. open the repository in offline mode This should be different from the current repository and click enable or disable the cache . This can be done by right clicking the dimension table and click create dimension and then we can manually define the hierarchy and its levels. if we want to enable the cache at table level . 75. 77. b.ini file use ENABLE under CACHE Section for System Level For tables. if for certain users only the column heading in the report should be changed? Using session variables for that user. if so where and how? Yes. What is a table alias in OBIEE 11g? Where and how will you create it? Table alias is used for creating self joins. rpd from development to production? For the RPD we can use the Merge option in Admin Tool and for dashboards and reports we can use Content Accelerator Framework. How will effect the changes for a report .68. What is write-back in obiee ? We can give a column as updatable and then view the reports. 73. How will you enable or disable caching in the system level and table level? In the NQSConfig. Examples of non system variables are user defined filters. 72. How OBIEE Developer can create report from two subject areas? From the Criteria Pane of the Report Created from First Subject Area come to the bottom of the page and click combine request. Session variable: session variable are of two types: system variable and non system variable.this option is called write back option. 74. How we can Port changes for dashboards. a. 70. then reload server metadata . 76. having a measure held at a certain level of the dimension. LDAP authentication 81. • Business Model • Mapping Layer • Presentation Layer. Examples Monthly Total Sales or Quarterly Sales To create a level based measure. Database authentication d. 82. Authentication is the procedure by which a system confirms. 80. What are the different layers of OBIEE 11g Repository? • Physical Layer. 79. Operaing system authentication b.com . What is Level Based Metrics? How we can create it? Level-base metrics means. What is Authentication? How many types of authentication.78. How Time based triggered report can be generated? Using Scheduler – ibots we can generate time based triggered report.
