How to communicate with JobScheduler from PHP scripts - e.g. to add jobs

Introduction - PHP XML Interface

How it works

JobScheduler – Program Interface

This document describes how applications can communicate with the JobScheduler. Possible tasks could be as follows:

Temporary creation of jobs
Starting jobs
Adding jobs
Changing runtime
Etc.

The communication is explained by the means of PHP examples. However you can use any other programming language of your choice.

Communication

The communication with JobScheduler takes place via TCP, where XML commands are transmitted. You can check the documentation for the possible XML commands: http://www.sos-berlin.com/doc/en/scheduler.doc/index.xml

Note: All changes, which are made using the xml-commands vie TCP-communication are not persistent. E.g. added jobs are no longer available after restarting the JobScheduler

Example

Adding of a job with the name myJob. The Job runs once a day at 6pm and lists the table c:\temp.

            <add_jobs>
              <job name="myJob"
                   title = "my first job">
                <script language="shell">
                <![CDATA[
                    dir c:\temp
                ]]>
                </script>
                <run_time>
                   <period single_start="18:00"/>
                </run_time>
              </job>
           </add_jobs>

Example with Telnet

telnet localhost 4454

The following XML string can be send e.g. via Telnet

(The JobScheduler receives commands)

        <add_jobs>
          <job name="myJob" title = "my first job">
            <script language="shell">
            <![CDATA[dir c:\temp  ]]>
            </script>  <run_time>
            <period single_start="18:00"/>
            </run_time>
          </job>
        </add_jobs>

(The JobScheduler answers)

         <?xml version="1.0" encoding="ISO-8859-1"?>
        <spooler>
          <answer time="2008-04-08 15:50:33.536">
            <ok/>
         </answer>
        </spooler>

Example with PHP Socket Communication (@fsockopen)

       //open Socket
      $socket = fsockopen("localhost", "4454", $errno,$errstr, 60);

      //build command

      $cmd = '<add_jobs><job name="myJob" title = "my first job"> <script';
      $cmd += 'language="shell">  <![CDATA[dir c:\temp  ]]>  </script> ';     
      $cmd += '<run_time> <period ';     
      $cdm += 'single_start="18:00"/></run_time></job></add_jobs>';

       //send command
      fputs( $socket, $cmd );

      //Close Socket
      fclose( $socket);

After the JobScheduler has answered, you can view the Job in the JobScheduler's web interface, JOC.

Evaluate Answer

The following function delivers the JobScheduler's answers in a single string. The JobScheduler delivers the answer via the same socket as was previously used during fputs, e.g. the answer can also be delivered directly after fputs.

       function get_answer($socket) {
       $answer = ''; $s = '';
       while ( !ereg("</spooler>", $s) && !ereg("<ok[/]?>", $s) ) {
         $s = fgets($socket, 1000);

         if (strlen($s) == 0) { break; }
         $answer .= $s;
         $s = substr($answer, strlen($answer)-20);


         // chr(0) am Ende entfernen.
         if (substr($answer, -1) == chr(0)) {
           $answer = substr($answer, 0, -1);
           break;
         }
       }
       $answer = trim($answer);

       return $answer;
     }

Communication with PHP Classes

For an application that sends commands to the JobScheduler it is very usefull to have a proper error handling. Apart from that, a higher level of abstraction is useful for understanding the source code. For this reason SOS GmbH offers a class for processing the communication. The class encapsulates the socket calls and provides a method for reading XML answers of the JobScheduler.

Installation

In your web directory set up a file called: packages.Into the folder scheduler put the file sos_scheduler_command_inc.php and into the folder class put the file sos_class.inc.php.
You can find these files unter scheduler/php_xml_interface/packages.zip
In your application program include the class with:require_once( 'scheduler/sos_scheduler_command.inc.php');

Example

The example can be realized with these classes as follows:

//open socket
$command = new SOS_Scheduler_Command(‘localhost’,4454, 60);
//build command
$cmd = '<add_jobs><job name="myJob" title = "my first job"> <script';
$cmd += 'language="shell">  <![CDATA[dir c:\temp  ]]>  </script> ';
$cmd += '<run_time> <period ';
$cdm += 'single_start="18:00"/></run_time></job></add_jobs>';
if (!$command->connect()) {
echo$get_error(). __FILE__ . __LINE__ ;
return 0;
}
//send command
$this->command->command($cmd);
if ($command->get_answer_error()) {
echo$command->get_error() . ‘ ‘ . __FILE__ . ‘ ‘ . __LINE__ ;
}
//close socket
$command->disconnect();

Commands with xml-php Interface

One of the key tasks for the communication with JobScheduler is the creation of XML commands. To this end, you could use string functions or DOM classes.
Another possibility is to use the xml-php-interface. The interface encapsulates the construction of XML commands and the communication with the JobScheduler. In this case the classes described in Communication with PHP Classes are used.

The advantage of using these classes is the easy handling when assembling the XML data stream.

Within your application you have to setup the Include directory.

`ini_set( 'include_path', 'packages' );`

Example

The example with these classes is realized as follows:

if(!defined('APP_SCHEDULER_HOST')) { define ( 'APP_SCHEDULER_HOST', 'localhost' ); }
if(!defined('APP_SCHEDULER_PORT')) {define( 'APP_SCHEDULER_PORT', '4454' ); }

//load missing classes and returns an object of the class
function &get_instance($class, $include_path='scheduler/', $extension='.inc.php') {
	if ( !class_exists($class) ) {
		include( $include_path . strtolower($class) . $extension );
	}
	$object = new $class;
	$object->host=APP_SCHEDULER_HOST;
	$object->port=APP_SCHEDULER_PORT;
	return $object;   
}
$job = &get_instance('SOS_Scheduler_Job','scheduler/');

//Setting some properties
$job->name           = "myJob";
$job->title          = "my first job ";

//Set the implentation
$job->script('shell')->script_source='dir c:\temp';

//The job has a runtime 
$job->run_time()->period()->single_start = "18:00";
$job_command = &get_instance('SOS_Scheduler_JobCommand_Launcher','scheduler/');

if (! $job_command->add_jobs($job))  {
	echo'error occurred adding job: ' . $job_command->get_error(); 
	exit; 
}

Example of Use

For the following examples it is assumed that this code is preceeding.

if(!defined('APP_SCHEDULER_HOST')) { define ( 'APP_SCHEDULER_HOST', 'localhost' ); }
if(!defined('APP_SCHEDULER_PORT')) { define ( 'APP_SCHEDULER_PORT', '4454' ); }
//load missing classes and returns an object of the class
function &get_instance($class, $include_path='scheduler/', $extension='.inc.php') {
if ( !class_exists($class) ) {
include( $include_path . strtolower($class) . $extension );
}
$object = new $class;
$object->host=APP_SCHEDULER_HOST;
$object->port=APP_SCHEDULER_PORT;
return $object;
}

The use of the php-xml interface is explained. You can find a detailed documentation of the classes in the formats PHP and DOC under: http://www….

At the end of each example you can see the XML code that will be send to JobScheduler.
