Auto-Generated Parameter Files

The basic external adapter framework, when started, writes its set of parameters (system and user-defined) to a parameter file.

This file is written in either:

Java properties
Shell assignments
Simple XML format

Commands then have full access to the parameter file.

There is an example of parameters in the simplified_xml_input_plugin.cnxml file.

             <Internal id="x_paramFile"
               label="Parameter File"
               type="string"
               default="/tmp/PARAMETER_FILE.txt"
             />
          <Internal id="x_paramFormat"
            label="Parameter Format"
            type="string"
            default="prop"
        />
     <Internal id="x_addParamFile"
       label="Add Parameter File"
       type="boolean"
       default="false"
/>

The parameter file is written to /tmp/PARAMETER_FILE.txt.

			directory=/home/sjk/work/aleri/cimarron
			/branches/3.1/examples/input/xml_tables
			filename=trades.xml
			platformAuth=none
			platformCommandPort=31415
			platformConnection=Connection1
			platformHost=sjk-laptop
			platformSqlPort=22200
			platformSsl=0
			platformStream=Trades

or a full list of parameters, in the Java properties format. Note the format can be specified as shell for shell assignments, or as xml for a simple XML format.

When x_addParamFile is specified as true,

			<Internal id="x_addParamFile"
				  label="Add Parameter File"
			   type="boolean"
				  default="true"
				/>

the argument /tmp/PARAMETER_FILE.txt is added to all commands prior to being executed.
