Getting Configuration Parameters

The JavaScript interface enables you to get two different sets of configuration properties, the filter specific properties, and the general replicator properties. The filter specific properties should be used to configure and specify configuration information unique to that instance of the filter configuration. Since multiple filter configurations using the same filter definition can be created, using the filter-specific content is the simplest method for obtaining this information.

  • Getting Filter Properties

    To obtain the properties configured for the filter within the static configuration file according to the context of the filter configuration, use the filterProperties class with the getString() method. For example, the dbrename filter uses two properties, dbsource and dbtarget to identify the database to be renamed and the new name. The definition for the filter within the configuration file might be:

    replicator.filter.jsdbrename=com.continuent.tungsten.replicator.filter.JavaScriptFilter
    replicator.filter.jsdbrename.script=${replicator.home.dir}/support/filters-javascript/dbrename.js
    replicator.filter.jsdbrename.dbsource=contacts
    replicator.filter.jsdbrename.dbtarget=nyc_contacts

    Within the JavaScript filter, they are retrieved using:

    sourceName = filterProperties.getString("dbsource");
    targetName = filterProperties.getString("dbtarget");

  • Generic Replicator Properties

    General properties can be retrieved using the properties class and the getString() method:

    master = properties.getString("replicator.thl.remote_uri");
