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