KB45848: How to Dynamically Select Intelligence Servers in a Cluster Using URL API to Connect to the Intelligence Server Cluster When the Node Specified in the URL Is Not Currently Running.

The following example shows the default behavior when running a report using URL API.

• Two Intelligence Servers (NODE1, NODE2) are in a cluster.
• Shutdown Intelligence Server, NODE2
• Run the report using the following URL. Please note NODE2 is specified as the target Intelligence Server. http://WebServerName/Strategy/asp/Main.aspx?Server=NODE2&Project=Strategy+Tutorial&Port=0&evt=4001&src=Main.aspx.4001&reportID=guid&visMode=0&reportViewMode=1&UID=Administrator&PWD=
•  The following error page is displayed since NODE2 is down: "Error in Login. Invalid Login Mode"
  

Setting a system defaults parameter, "automaticallyFindIServer" in sys_defaults.xml to 1, the web server will select a connected Intelligence Server automatically.

1. Create a new plugin using the Web Customization Editor.
2. In the Application Settings tab, navigate through Strategy Web Configuration > Web Configuration Settings > System Defaults.
3. Look for the option named "automaticallyFindIServer", and double-click to open it in the editor.
4. Change the value to "1" and save the changes.
5. Restart the web server.
6. Note that the report runs on NODE1. 

Note:

• Out of the box files should not be modified directly, this change should instead be made within a plugin using the Web Customization Editor.

 
The example provided in this document is provided “as-is” to the user and assumes that the user:

• Can program, compile (e.g. javac, jikes, etc.), and execute Java programs
• Can configure environment variables (e.g. JAR files, property files, etc.)
• Have all the necessary tools to create Java applications (JDK, IDE, etc.)
• Has access to the Strategy SDK documentation.
• Has read the customization warning at the bottom of this document

PREREQUISITES: 
For the sample to work, the Strategy Web JAR files must be accessible by the Java Runtime Environment. The Strategy Web JAR files can be found under:

• Strategy Web Universal (JSP): {web_root}/WEB-INF/lib directory.
• Strategy Web (.NET): Program Files\Common Files\Strategy directory.

Note: More elaborate programs will require additional library files and are out of the scope of this document.
ADDITIONAL INFORMATION:
The Strategy SDK allows you to customize the standard Strategy Web interface, and extend and integrate the Strategy business intelligence functionality into other applications. However, before changing the way Strategy Web products look or behave, it is helpful to understand how the application is built. For more information regarding the Strategy Web architecture or the process of customizing Strategy Web, please refer to Strategy Developer Zone (https://developer.microstrategy.com).
To access the Strategy Developer Zone, you must have access to the Strategy Knowledge Base, you must have purchased the Strategy SDK, and you must be current on your Strategy maintenance agreement. If you are a US-based business and believe that you satisfy all three of these conditions but you do not have access to the Strategy Developer Zone, please contact Strategy Technical Support at support@microstrategy.com or at (703) 848-8700. If you are an international business, please contact Strategy Technical Support at the appropriate email address or phone number found at https://www.microstrategy.com/en/support/contact-support.
