Microstrategy Caches explained

Microstrategy Caches

Improving Response Time: Caching

cache is a result set that is stored on a system to improve response time in future requests. With caching, users can retrieve results from Intelligence Server rather than re-executing queries against a database.


To delete all object caches for a project
1In Developer, log into a project. You must log in with a user account that has administrative privileges.
2From the Administration menu, point to Projects, and then select Project Configuration. The Project Configuration Editor opens.
3Expand Caching, expand Auxiliary Caches, then select Objects.

To delete all configuration object caches for a server

1Log in to the project source.
2From the Administration menu in Developer, point to Server, and then select Purge Server Object Caches.
4Click Purge Now.


To purge web cache follow the steps in the link below:

To purge various other caches go the MSTR link below: 

Improving Response Time: Caching

A cache is a result set that is stored on a system to improve response time in future requests. With caching, users can retrieve results from Intelligence Server rather than re-executing queries against a database.

Intelligence Server supports the following types of caches:
  • Page caches: When a user views a published dossier the Intelligence Server generates one cache per page, so that the cache can be hit when the user switches between pages.

  • Result caches: Report and document results that have already been calculated and processed, that are stored on the Intelligence Server machine so they can be retrieved more quickly than re-executing the request against the data warehouse. Intelligent Cubes can function in a similar fashion to result caches: they allow you to store data from the data warehouse in Intelligence Server memory, rather than in the database. Intelligent Cubes are part of the OLAP Services add-on to Intelligence Server. For detailed information about Intelligent Cubes.

  • The History List is a way of saving report results on a per-user basis. 

  • Element caches: Most-recently used lookup table elements that are stored in memory on the Intelligence Server or Developer machines so they can be retrieved more quickly. 

  • Object caches: Most-recently used metadata objects that are stored in memory on the Intelligence Server and Developer machines so they can be retrieved more quickly. 

You specify settings for all cache types except Page caches and History List under Caching in the Project Configuration Editor. Page cache settings are configured via Application Properties > Dossier Cache Management in MicroStrategy Workstation. History List settings are specified in the Intelligence Server Configuration Editor.
Result, element, and object caches are created and stored for individual projects; they are not shared across projects. History Lists are created and stored for individual users.
To make changes to cache settings, you must have the Administer Caches privilege. In addition, changes to cache settings do not take effect until you stop and restart Intelligence Server.

Customers Who Live in the Same City as Call Centers

Customers Who Live in the Same City as Call Centers Your new utility company has call centers located throughout the country, and your recent surveys indicate that customers who live in the same city as a call center are particularly satisfied with service due to extremely rapid repairs during power outages. To begin your new advertising campaign, you want to generate a list of Call Centers that coincide with Customer Cities. The following steps create an attribute-to-attribute qualification filter that generates the list of desired cities. To Create an Attribute-To-Attribute Qualification that Compares the Call Center and Customer City Attributes In MicroStrategy Web, log in to a project. Open any folder page (for example, click Shared Folders on the home page). Click the  Create Filter  icon  . From the Object browser on the left, select the  Customer City  attribute from the Customers hierarchy and drag it to the filter pane on the right. Change  Qualify...

Administration standards to optimize network data transfer speeds

Optimization standards to help developers work with the System Administrator to optimize network data transfer speeds: Place all server components in the same segment to minimize latency between the Intelligence Server, Web server, data warehouse server, and metadata server Expand bandwidth and minimize latency between servers and clients to ensure that bottlenecks do not occur when data is requested over your network Use HTTP compression between the Web servers and Web clients to achieve maximum throughput between these components Configure a Web proxy server to handle caching and reduce the load on the Web server

Create an alert-based subscription in MicroStrategy Distribution Services

Create an alert-based subscription in MicroStrategy Distribution Services on Web Subscription to a report or Report Services document which will be executed when a certain conditional threshold is met based on another executing report. For example, a scheduled report executes which shows the Revenue by day for the past week. If the Revenue on any one day falls below a certain value, a subscription to another report or Report Services document can be triggered and delivered to a recipient. An alert based subscription can only be created directly on a report; however, another report or Report Services document can be delivered when the alert based subscription is triggered. Note: you need a grid report to create an alert and you cannot create if you want to create on a document with text boxes. The following example will walk through the basic steps on how to setup a subscription based on an alert like this: Follow the brief  steps bel...

Relationship with Report Filter options for Levels metrics

Relationship with Report Filter options for Levels metrics You can define how the report filter affects the metric calculation. From the  Relationship with Report Filter  drop-down list, select one of the following: • To include only data that meets the conditions in the report filter in the metric calculation, select  Standard filtering . • To raise the level of the report filter to the level of the target, if possible, then apply the report filter to the metric calculation, select  Absolute filtering . For example, the report filter contains the Washington, DC, Boston, and New York call centers, but the Revenue metric is calculated at the Region level. Because Call Center is a child attribute of Region, the report filter's level is raised to the Region level, and the report filter is treated as if it includes the regions that contain Washington, DC, Boston, and New York (in this case, Mid-Atlantic and Northeast). Data from all call centers in the Mid-At...

Bursting file subscriptions Microstartegy

Bursting file subscriptions: Delivering  parts of reports across multiple files: Large MicroStrategy reports and documents are often broken up into separate pages by attributes. In a similar way, with Distribution Services, you can split up, or burst, a report or document into multiple files. When the subscription is executed, a separate file is created for each element of each attribute selected for bursting. Each file has a portion of data according to the attributes used to group data in the report (page-by axis) or document (group-by axis). Ex:, you may have a report with information for all regions. You could place Region in the page-by axis and burst the file subscription into the separate regions. This creates one report file for each region. As a second ex:, if you choose to burst your report using the Region and Category attributes, a separate file is created for each combination of Region and Category, such as Central and Books as a report, Central and Ele...
