If you're looking for Hyperion Interview Questions for Experienced or Freshers, you are at the right place. There are a lot of opportunities from many reputed companies in the world. According to research, Hyperion has a market share of about 8. So, You still have the opportunity to move ahead in your career in Hyperion Development.
This course will help you to achieve excellence in this domain. Financial applications are generally dense structures and normal analytical cubes are sparse. Here we also need to understand what these dense and sparse members are. When the intersections or cells of two dimensions mostly contain a value it is dense. Say for example we have two dimensions period Month or quarter and region and we are calculation the sales amount.
Generally, maximum regions countries, cities will have some sales value for a particular month or quarter. Hence we can say that our period dimensions would be dense.
But now instead of a period, consider another dimension product. Now there are some products which are sold in only some particular regions hence for them there will be no values in other regions or will have a very low percentage of data values hence the structure will become sparse. Ans: To automate the process of creating dimensions with thousands of members.
Ans: 1. Parent-Child references. Ans: We cannot define that as Generation 1 is not valid. Attribute calculation dimensions which include five members with the default names sum, count, min, max and avg are automatically created for the attribute dimensions and are calculated dynamically.
Ans: Yes, we can do that but it is recommended to use a separate rule file for each dimension. Ans: UDA represents the class of the members. Aliases are just other names of the members. Ans: Yes. You can query a member for its UDA in a calculation script. If gen 2 and gen 4 exists, we must assign gen 3. Attribute dim- No Impact as they perform only dynamic calculations.
Ans: The highly impact the report performance as the attributes are calculated dynamically when referenced in the report. For very large number of att dim displayed in the report, the performance could drastically reduce. But only one database per application is recommended.
Ans: No. Hence if the application is ASO, the databases it contains will be that type only. Ans: To communicate between Essbase and Microsoft office tools. Ans: Integration services and in version 11, we have Essbase studio.
We can manage our server resources by starting only the applications which receive heavy user traffic. When an application is started, all associated databases are brought to memory.
We can have multiple instances of an Essbase server on a single machine and there will be different sets of windows services for all these instances. Ans: It prevents members from being consolidated across any dimension.
Ans: Lower-level members and associated data remain in the relational database whereas upper-level members and associated data reside in the Essbase database. Ans: In the process, it calculates more blocks than is necessary. Sometimes it is necessary to perform a top-down calculation to get the correct calculation results. Ans: If we have a single processor, we will use serial calculation but if we have multiple processors we can break the task into threads and make them run on different processors.
Ans: Analytic services or Essbase Services locks the block and all other blocks which contain the Childs of that block while calculating this block is block locking system. Ans: The statement should be just the opposite. As dynamic calc members are calculated when requested, the retrieval time should increase.
You can link multiple objects to a single data cell. These linked objects are stored in the server. Ans: Three types of partitions are there. Transparent partition: A form of shared partition that provides the ability to access and manipulate remote data transparently as though it is part of your local database.
The remote data is retrieved from the data source each time you request it. Any updates made to the data are written back to the data source and become immediately accessible to both local data-target users and transparent data source users 2.
Replicated Partition 3. Linked Partition. Check Out Hyperion Tutorials. Ans: You should have the role of Application manager for the specified application. Login attempts allowed before username is disabled. Number of inactive days before username is disabled. Number of days before the user must change the password. Depend on which database you are going to create. If you are creating BSO then you can create more than 1 db per application.
Sometimes it is necessary to perform the top-down calculation to get the correct calculation results. Ans: OTL,. RUL and. Ans: A buffer in memory that holds compressed data. PAG files. Ans: Essbase calculation functions that you develop in the Java programming language and then add to the standard Essbase calculation scripting language by means of MaxL. Ans: Hyperion Administrative services console provides a migration utility to do this but only the application, database objects are migrated and no data is transferred.
Related blog : Hyperion Online Certification Training. Ans: Essbase macros that we write with Essbase calculator functions and special macro functions.
Custom-defined macros use an internal essbase macro language that enables you to combine calculation function and operate on multiple input parameters. Ans: A data block containing cells that have been changed since the last calculation. Upper-level blocks are marked as dirty if their child blocks are dirty that is, have been updated.
Ans: To automate the process of creating dimensions with more members, where it will take a lot of time in creating manually. Ans: It prevents members from being consolidate across any dimension. Ans: So many log files are there in essbase, but the important log files are 1. Application log 2. Ans: A classification of a member in a dimension.
You can select and group members based on their associated attributes. You can also specify an attribute when you perform calculations and use calculation functions. Eg: The database in Sample Basic which has product dimension has some attributes like size, package type, and flavor.
Ans: Objects get locked to prevent users to make simultaneous and conflicting changes to Essbase database objects. By default whenever an object is accessed through the Administrative services console or Excel spreadsheet add-in, it gets locked.
Ans: Essbase supports two different types of attributes. User-Defined attributes 2. Simple attributes User-Defined attributes: The attributes that are defined by the user. Simple attributes: Essbase supports some attributes, they are: Boolean, date, number, and string. Ans: A method of controlling access to database cells in essbase. A filter is the most detailed level of security, allowing you to define varying access levels different users can have to individual database values.
For example, the value for Qtr1 is the same as the value for Jan. For example, the value for Qtr1 is the same as the value for Mar. Ans: They highly impact the report performance as the attributes are calculated dynamically when referenced in the report.
Ans: Usually the outline is optimized using the hourglass design for dimension ordering i. Dimension with Accounts tag 2. Dimension with Time tag 3. Largest Dense dimension 4. Smallest dense dimension 5.
Smallest Sparse dimension 6. Largest Sparse dimension. Ans: There are several ways to optimize load 1. Grouping of Sparse member combinations 2. Making the data source as small as possible 3.
Hyperion EssBase Interview Questions & Answers
What are the two storage options available in Essbase and what are the differences? Can we build dimensions directly from data sources without using rule files. When do we generally use build rules files? What are the three primary build methods for building dimensions? In what case we can define generation 1 to a field in generation build method. Suppose we have assigned Generation 2 and Generation 4 as of now and think of adding generation 3 later some time. Can we build the dimension.

Can we build the dimension. Yes, we can do that but it is recommended to use separate rule file for each dimension. Answer Yes. Answer No. Answer The data block is the structure that is comprised of the dimensions tagged as dense in the Essbase outline. The block is defined by the intersections of all dense dimension member intersections. When data blocks and index entries are persisted to disk, the data blocks are compressed and stored within ESS.
