Loading Intelligent Cubes when Intelligence Server Starts

When Intelligence Server is started there are various tasks that are processed to prepare a reporting environment. You can include loading all published Intelligent Cubes as one of the tasks completed when Intelligence Server is started. This affects when the load time required for Intelligent Cubes occurs.

Below are the steps to enable or disable loading Intelligent Cubes when Intelligence Server starts

In Developer, log in to a project with a user account with administrative privileges.
Right-click the project and select Project Configuration.
Expand Intelligent Cubes, and then select General.
Select or clear the Load Intelligent cubes on startup check box to enable or disable loading Intelligent Cubes when Intelligence Server starts.
Click OK.

It is always useful to consider whether to load Intelligent Cubes at Intelligence Server startup or when a report is executed that accesses a published Intelligent Cube are described in the table below:

Method	Pros	Cons
Loading Intelligent Cubes when Intelligence Server starts	Report runtime performance for reports accessing Intelligent Cubes is optimized since the Intelligent Cube for the report has already been loaded. This practice is a good option if Intelligent Cubes are commonly used in a project.	The overhead experienced during Intelligence Server startup is increased due to the processing of loading Intelligent Cubes. All Intelligent Cubes for a project are loaded into Intelligence Server memory, regardless of whether they are used by reports or not.
Loading Intelligent Cubes when a report is executed that accesses a published Intelligent Cube	The overhead experienced during Intelligence Server startup is decreased as compared to including loading Intelligent Cubes as part of the startup tasks. If Intelligent Cubes are not required by any reports, then they do not need to be loaded into Intelligence Server and no overhead is experienced. This practice is a good option if Intelligent Cubes are supported for a project, but some of the Intelligent Cubes are rarely used in the project.	Report runtime performance for reports accessing Intelligent Cubes can be negatively affected as the Intelligent Cube must first be loaded into Intelligence Server. You can also load Intelligent Cubes manually or with subscriptions after Intelligence Server is started.

The procedure below describes how to enable or disable loading Intelligent Cubes when Intelligence Server starts.

The act of loading an Intelligent Cube can require memory resources in the area of two times greater than the size of an Intelligent Cube. This can affect performance of your Intelligence Server as well as the ability to load the Intelligent Cube.

OLAP features in Microstrategy

OLAP features in Microstrategy MSTR OLAP Services uses Intelligent Cube Technology—an in-memory version of report data that can 1 About MicroStrategy OLAP Services can be manipulated by the MicroStrategy Analytical Engine. MicroStrategy Desktop, Web, and Office users can slice and dice data in reports within Intelligent Cubes without having to re-execute SQL against the data warehouse. Many of the standard OLAP features that MicroStrategy provides out of the box, such as: Page-by Pivoting Sorting Subtotals Banding Aliasing Outline mode Thresholds etc.. With an OLAP Services license, user can perform additional OLAP analysis, using the following features: Displaying data on the fly: dynamic aggregation, page Creating metrics on-the-fly: derived metrics, Defining attribute elements on-the-fly: derived elements, Filtering data on the fly: view filters and metric filters, Importing data as an Intelligent Cube

To resolve this: Admin should delete the database connection caches and create a new DSNs in case they are sharing DSNs to connect to different databases. In addition, change the settings for the ‘Connection lifetime’ and the ‘Connection idle time out’.

Logical Views to specify an outer join between two attribute lookup tables when only attributes are on a report

Logical Views to specify an outer join between two attribute lookup tables when only attributes are on a report Apart from using the VLDB properties to create the left outer join, article describes how to use the Logical View to specify an outer join between two attribute lookup tables when only attributes are on a report. This method exists as attribute only outer joins will not be generated on their own by the MicroStrategy SQL engine. This is because they are only necessary with r agged/unbalanced hierarchies which are not supported as null attribute IDs are not supported (parent elements with no child elements or child elements with no parents). Brief instructions are provided using the example below. Consider, two attributes: Parent01 and Child01 have a parent-child relationship. Their Lookup tables are defined, as follows Parent01 Child01 Note that although there are 4 ID values for the attribute Parent01, there is no defined relationship ...

Fiscal Week, Fiscal Month, Fiscal Quarter and Fiscal Year calculations in Microstrategy

Fiscal Week, Fiscal Month, Fiscal Quarter and Fiscal Year calculations in Microstrategy FiscalWeek Returns the numeric position of a week within a fiscal year, for a given input date. This function is useful in financial reporting when the start of the fiscal year is different than the start of the calendar year. Syntax FiscalWeek< firstWeekDay , firstMonth >( Date / Time ) Where: • Date / Time is the input date or timestamp. • firstWeekDay (default value is 1) is a parameter that determines which day of the week is considered as the first day of the week. You can type an integer value from 1 to 7, with 1 representing Sunday, 2 representing Monday, and so on until 7 representing Saturday. • firstMonth (default value is 1) is a parameter that determines which month is considered as the start of the fiscal year. You can type an integer value from 1 to 12, with 1 representing January, 2 representing February, and so on until ...

Settings for Outer Join between metrics in MicroStrategy

Settings for Outer Join between metrics in MicroStrategy MicroStrategy adopts multi-pass logic to determine the execution plan for a report. This means that every metric is evaluated in separate SQL passes. Outer Joins come into play when MicroStrategy Engine merges the results from all SQL passes into one report. For a multi-pass report, different Outer Join behaviors can give the user completely different results. In addition, report metrics can be of different types which can, in some cases, influence the result of the outer join. In MicroStrategy, there are two settings that users can access to control Outer Join behavior : Formula Join Type and Metric Join Type . Metric Join Type: VLDB Setting at Database Instance Level Report and Template Levels Report Editor > Data > Report Data Options Metric Level Metric editor > Tools > Metric Join Type Control Join between Metrics Formula Join Type: Only at Compound/Split...

Predictive modelling in Data Science using Microstrategy

Creating a predictive modelling in MicroStrategy MicroStrategy Data Mining Services has been evolving to include more data mining algorithms and functionality. One key feature is MicroStrategy Developer’s Training Metric Wizard. The Training Metric Wizard can be used to create several different types of predictive models including linear and exponential regression, logistic regression, decision tree, cluster, time series, and association rules. Linear and exponential regression The linear regression data mining technique should be familiar to you if you have ever tried to extrapolate or interpolate data, tried to find the line that best fits a series of data points, or used Microsoft Excel’s LINEST or LOGEST functions. Regression analyzes the relationship between several predictive inputs, or independent variables, and a dependent variable that is to be predicted. Regression finds the line that best fits the data, with a minimum of error. For example, you have a dataset ...
