Hyperion Essbase Interview Questions and Answers Can we create more than 2 dimensions using only one build rule file. Ans: Yes, we can do that but it is recommended to use seperate rule file for each dimension. What is UDA( user defined attributes). How are they different than Aliases. Ans: UDA represents the class of the members. Aliases are just another names of the members. both are different and has different usage. What is the Extension of Cal Scripts, Batch files, outline, and Rule File? Ans: Rule file is .rul Calc Script is - .csc Batch files - .bat outline - .otl Why are Filters used? Ans: If you want to grant access to all dimensions then you wouldn't use a filter. Just grant read access for the database to the user and/or group. The only reason you would use a filter is if you wanted to restrict access. What are Dense and Sparse Dimensions? Ans: Dense: A dimension which has the high probability that data exists for every combination of dimension members Sparse: A dimension which has low probability that data exists for every combination of dimension members Can we query a member for its UDA in a calculation script. Ans: Yes. You can query a member for its UDA in a calculation script. How does UDA's impact database size? Ans: Absolutely no impact as UDA's do not require additional storage space. How does Essbase recover from a database crash? Ans: After a database crash or server interruption, Essbase automatically recovers a database after rolling back the transactions that were active at that time. Can we build dimensions directly from data sources without using rule files. Ans: No. When do we generally use build rules files? Ans: To automate the process of creating dimensions with thousands of members.

What are the three primary build methods for building dimensions? Ans: 1. Generation references 2. level references 3. Parent-Child references. What is the difference between ASO & BSO? Ans: i. We cannot create more than 1 database in ASO, but we can create more than 1 db per application. If we have more dimensions (generally more than 10) then we will go for ASO ii. we cannot write back in ASO, but we can write back in BSO. iii. Most of the dimensions are sparse in ASO whereas in BSO most of them are dense. How can we backup an aggregate storage database? Ans: To back up an aggregate storage database, copy the application directory ARBORPATH/app/appname. How can you make a Max L script run at a specified time? Ans: MaxL scripts can be called from a BAT file which is used for scheduling. I have created an application with one database in Essbase at test environment and now needs to copy the entire application with all security permissions to the production server which is not connected to the test server. How can I do that? Ans: You can acheive this using migration wizard to migrate an application to a text file which you can take physically to the production server. To know how you can do that, take a look at this post Essbase Application Migration. In what case we can define generation 1 to a feild in generation build method. Ans: We cannot define that as Generation 1 is not valid. What is Incremental Dimensional Built and one time Dimension Built? Ans: Incremental Dimensional Build: Builds and reads from different data sources for dimension builds and delay restructuring until all data sources have been processed.

Hyperion Planning Interview Questions Answers What are the different types of LOG Files? Ans: So many log files are there in essbase, but the important log files are

1. 2. 3. 4. 5.

Application log Essbase.log Configtool.log eas_install.log essbaseserver-install.log

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. Ans: No. If gen 2 and gen 4 exists, we must assign gen 3. What are attributes? 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. We can add these attributes to the dimensions where we can retrieve the data like for example to retrieve “coke with 8 Oz with bottles”, this is useful for generating reports. Why do objects gets locked and when does this happens? Ans: Objects gets locked to prevent users to make simultaneous and conflicting changes to Essbase database objects. By default whenever an object is accessed through Aministrative services console or Excel spreadsheet add-in, it gets locked. What is the difference between UDA's and Attribute dimensions? Ans : Attribute dimensions provides more flexibility than UDA's. Attribute calculations dimensions which include five members with the default names sum, count, min, max and avg are automatically created for the attribute dimensions and are calculate dynamically. How does Attribute dimensions and UDA's impact batch calculation performance? Ans: UDA's- No Impact as they do not perform any inherent calculations. Attribute dim- No Impact as they perform only dynamic calculations. What are different types of attributes? Ans: Essbase supports two different types of attributes. 1. 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. What are filters? 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. What is TB First and TB Last?

Ans: TB First: in the Sample.Basic database, the accounts member Opening Inventory is tagged as TB First. Opening Inventory consolidates the value of the first month in each quarter and uses that value for that month’s parent. For example, the value for Qtr1 is the same as the value for Jan. TB Last: in the Sample.Basic database, the accounts member Ending Inventory is tagged as TB Last. Ending Inventory consolidates the value for the last month in each quarter and uses that value for that month’s parent. For example, the value for Qtr1 is the same as the value for Mar. How can we display UDA's in reports? How do they impact report report performance. Ans: UDA's values are never displayed in the reports and hence do not impact report performance. How does Attribute dim impact report performance? Ans: They 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. While loading the data, you have applied both the selection criteria as well as rejection criteria to a same record. What will be the outcome. Ans: The record will be rejected. How is data stored in the Essbase database? Ans: Essbase is an file based database where the data is stored in PAG files of 2 GB each and grows sequentially.
