getXMLACatalogs(proxyURL: String, dataSourceInfo: String, callbackHandler: Function, username: String, password: String)

[starting from version: 1.5]

One of four API calls of OLAP/XMLA connectivity diagnostics.

Obtains a list of all available catalogs on a given data source by proxyURL and dataSourceInfo. Returns an Array of catalog names.

Parameters

• proxyUrl – String. The path to proxy URL to the OLAP data source, such as Microsoft Analysis Services and Mondrian.
• dataSourceInfo – String. The service info of the OLAP data source.
• callbackHandler – Function. A JS function which will be called when the component obtains a list of all available catalogs.
• username (optional) – String. The name of the user account at the server. This parameter is necessary to complete the authentication process.
• password (optional) – String. The password to the user account at the server. This parameter is necessary to complete the authentication process.

Example

OLAP/XMLA connectivity step by step. First, getXMLADataSources() obtains a list of all data sources by given URL (for example: 'http://olap.flexmonster.com/olap/msmdpump.dll') and getXMLAProviderName() returns type. Second, getXMLACatalogs() gets all available catalogs for the first data source from the list of available data sources. Then getXMLACubes() obtains a list of all cubes for the first catalog of the list of available catalogs. Finally, connectTo()uses all the information about data source to connect to it:

var proxyUrl = 'http://olap.flexmonster.com/olap/msmdpump.dll'; 
var dataSourceInfo = ''; 
var type = ''; 
var catalog = ''; 
var cube = ''; 

function diagnostic() {
  getDataSources(); 
} 

function getDataSources() { 
  flexmonster.getXMLADataSources(proxyUrl, onDataSourceLoaded); 
} 

function onDataSourceLoaded(result) { 
  dataSourceInfo = result[0]; 
  type = flexmonster.getXMLAProviderName(proxyUrl); 
  flexmonster.getXMLACatalogs(proxyUrl, dataSourceInfo, onCatalogsLoaded); 
} 

function onCatalogsLoaded(result) { 
  catalog = result[0]; 
  flexmonster.getXMLACubes(proxyUrl, dataSourceInfo, catalog, onCubesLoaded); 
} 

function onCubesLoaded(result) { 
  cube = result[0]; 
  flexmonster.connectTo({ 
    type: type,
    proxyUrl: proxyUrl, 
    dataSourceInfo: dataSourceInfo, 
    catalog: catalog, 
    cube: cube 
  }); 
} 

diagnostic();
