The following requirements must be met before the JOC Cockpit can be installed and run:

• The JOC Cockpit can only be installed alongside a JobScheduler Master version 1.11 and newer.
  

  Display feature availability
  StartingFromRelease 1.11

   
• JOC Cockpit requires access to the DBMS that operates the JobScheduler database.
• An JVM 1.8 has to be installed. 
  The JAVA_HOME variable should point to the location of the JDK or JRE.
• If a MySQL DBMS is being used by the JobScheduler, the MySQL timeout should be checked and if necessary modified. 
  • The default timeout for MySQL is relatively short and the JOC Cockpit does not have a mechanism for keeping the connection open over longer periods of time such as overnight. 
  • See the following article for instructions about how to change the MySQL DBMS timeout variable:
    • Database Connections to MySQL get lost
  • If the DBMS timeout is too short users will get an "Unauthorized to access JOC Cockpit" message together with a JOC 407 error message after submitting their credentials. However, restarting JOC Cockpit web service / demon will create a new database connection and allow authorized users to log in again. 

Operating Systems

The JOC Cockpit is available for Linux and Windows operating systems and the same archive can be used for installation on 64-bit and on 32-bit systems. See the Which platforms is JobScheduler available for and what platform support is provided? article for more information.
