Trick to execute OS command on SAP PI

Dear Friends,

Usually a PI developer will not get an OS level access to the system and he has to be heavily reliant on a SAP technical consultant (My basis friend hates me when I call him a basis guy ) to get any OS level job done. In dual stack systems, one could execute external OS commands on SM49 t-code.

So, a simple alternative is to use the below code snippet on either a UDF or java-mapping.

try
{
   java.lang.Runtime rt = java.lang.Runtime.getRuntime();
        // Start a new process: UNIX command ls
        java.lang.Process p = rt.exec("ls");
        // You can or maybe should wait for the process to complete
        p.waitFor();
      
container.getTrace().addWarning("Process exited with code = " + p.exitValue());
// System.out.println("Process exited with code = " + rt.exitValue());
        // Get process' output: its InputStream
        java.io.InputStream is = p.getInputStream();
        java.io.BufferedReader reader = new java.io.BufferedReader(new InputStreamReader(is));
        // And print each line
        String s = null;
        while ((s = reader.readLine()) != null) {
container.getTrace().addWarning("Process exited with code = " + s);
            //System.out.println(s);
        }
        is.close();
}catch(Exception e)    
{
e.printStackTrace();
}
 
 
 
 
return input;

Hope this is useful!!
