JOC Cockpit, the JS7 JobScheduler Operations Center GUI for browsers brings a completely new user experience - it features highlights such as security, responsive design and near real-time information. Find a full list of Features.

The following programming interfaces are available:

• JS7 JobScheduler REST Web Service (JSON)
• JS7 PowerShell Module

The JS7 JobScheduler JOC Cockpit user interface and JS7 JobScheduler Controller run on Windows and Linux operating systems. The JS7 JobScheduler Universal Agent can be operated on any platform. Agentless Scheduling using SSH is available for the execution of jobs on any server.

The JS7 JobScheduler uses a database to store the status of jobs, job chains and orders as well as job protocols and the job history. The database allows such information to be persistent, allowing, for example a job or order to be restored to its previous state after a JS7 JobScheduler restart or in the event of a failover.

More information: Which Database Management Systems are supported by JS7 JobScheduler?

The JS7 JobScheduler uses two methods for remote execution: JS7 JobScheduler Universal Agents and Agentless Scheduling per SSH.

• Agents are used in a Controller / Agent Cluster and are controlled by a Controller JS7 JobScheduler. They allow a simplified roll-out and do not require individual configuration or a database connection.
• Remote execution by SSH does not require a JS7 JobScheduler component on the remote server: instead an existing SSH server is used to create a secure shell and execute commands and programs.

Central configuration allows the efficient distribution of configuration files from a central source to JS7 JobScheduler Agent instances managed by a JS7 JobScheduler Controller. The single point of configuration ensures accurate and punctual delivery of the configuration data to all instances.

Connection Management

• The connection of the user's browser to the JOC Cockpit can be secured by HTTPS.
• The connection of the JOC Cockpit - REST Web Service to the JS7 JobScheduler Controller can be authenticated and secured by HTTPS.
• The connection by a JS7 JobScheduler Controller to its Agents can be authenticated and secured with HTTPS.

Access Management

• Enforce Authentication and Authorization for users.
• Enable secure integration with LDAP directory services such as Microsoft Active Directory
• Strengthen certificate authentication mechanisms (single / two factor authentication)
• Integrate HashiCorp® Vault Authentication Server with JS7 - Identity Services

Credentials Management

• Store sensitive information such as passwords for jobs in a Credential Store.
• Use of the Windows Credential Manager for secure user switching of jobs with JS7 JobScheduler Agents.

The JS7 JobScheduler can be implemented to provide high availability and fault tolerance. A number of options are available:

• Passive Cluster includes the set-up of a Primary JS7 JobScheduler Controller and redundant Backup JS7 JobScheduler Controller.
• JOC COCKPIT/Controller/Agent Resilience includes measures for reconciliation and recovery. 
• JOC COCKPIT/Controller/Agent Redundancy includes the use of clustered JS7 JobScheduler JOC COCKPIT, Controller instances and Agent bundles.

The JS7 JobScheduler's unique concept includes the use of jobs within workflows and dependencies:

• Jobs are the basic unit for the processing of executable files (programs, scripts, commands etc.).
• Workflows can be seen as an assembly line on which a number of job nodes are passed sequentially & parallel
• Orders represent triggers that will cause a job to be started based on calendar events.

Time events are one way of starting jobs, workflows and orders, with Start Times being set for predefined points in time such as a time of day, weekday, day of month etc. Job activities can also be limited to time-slots, i.e. jobs have to wait for a time-slot to be reached, e.g. between 8am and 11am.

Authentication and Authorization

The JOC Cockpit brings user authentication and authorization to the JS7 JobScheduler.

Authentication can either take place against an JS7 Identity Services compliant configuration, an LDAP compliant directory service, e.g. Microsoft Active Directory, or Certificate Based Authentication. Authentication against multiple realms is possible.

Authorization is configured by roles and permissions and an example set of roles and permissions is provided with the JOC Cockpit installation.

The JOC Cockpit is able to handle authentication of multiple users and their authorization for multiple JS7 JobSchedulers simultaneously. It also includes an editor in the Manage Accounts view for the configuration of authentication and authorization.

The Audit Log allows compliance and operations reporting requirements for job scheduling activities to be met by providing an automatic and secure record of all actions that users of the JS7 JobScheduler Web Service - including JOC Cockpit users and external applications - perform on job-related objects. The Audit Log lists the relevant JS7 JobScheduler objects - Jobs, Workflows, Orders, etc. - and any actions that modify their status.

The JS7 JobScheduler comes with its own mail client, which it can use to send notifying e-mails in the event of, for example, jobs ending in error.

Notification Features:

• JOC Cockpit Notifications: Visualizes notifications in the JOC Cockpit user interface
• Notification of Scheduling Events in Near Real-Time to System Monitor
• Notification by Mail

The JOC Cockpit notifies the user about scheduling events from all the JS7 JobScheduler Controller and Controllers Clusters being operated from the JOC Cockpit in near real-time.This is in addition to the near real-time updating of state-related information such as the number of jobs running, order progress or the orders currently in error throughout the JOC Cockpit.

The JOC Cockpit is a modern and responsive user interface. The JOC Cockpit can be accessed from any modern web browser – including those on tablets – and will adjust to the end user device.

The JOC Cockpit's web interface is automatically updated in near real-time. This includes information about running jobs, orders and job failures.

The JS7 JobScheduler comes with a number of powerful interfaces that are targeted at the following scenarios:

• Implementing jobs and monitors that can, for example, check execution results and decide on specific actions. Such implementations often make use of the REST API Interface to check and manipulate JS7 JobScheduler Objects.
• Developing individual programs and complex workflows, for example, using the Rest Web Service API. These jobs can be used to manipulate JS7 JobScheduler objects - for example, to create and submit orders from an individual application.

The JS7 JobScheduler comes with a powerful REST Web Service interface for access by external applications.

This interface is used for :

• Any operations can be effected by use of the REST API
• Operations include inventory management, monitoring and control of workflows and jobs, for example to start workflows, to cancel jobs etc.

The JS7 JobScheduler PowerShell Module offers command line operation for inventory management, monitoring and control from a single point of operation, regardless of the operating system the instance is running on. It simplifies automatic testing and monitoring procedures and the integration with other applications and allows, for example, orders or events to be automatically generated.

The JS7 JobScheduler comes with a number of instructions for use with complex workflows.

Theses instructions allow to process parameters, to handle errors in job execution (retry, try/catch), to wait for other workflows or start other workflows based on conditions.

The JS7 JobScheduler comes with a number of methods for error handling, these include:

• Suspended order: the order waits to be resumed later on the job in error. 
• Retry instruction: make an order repeatedly try to continue processing after a predefined time interval
• Try/Catch instruction adds error handling if the Try block tasks fail, the Catch block tasks are executed, otherwise they are ignored.
•  Use individual return codes to manage the success or failure

Locks can be used to manage the use of resources such as databases or printers:

• Locks
  • Limit the number of jobs that access the same resources, e.g. databases, in parallel.
  • Allow mutual exclusive access, i.e. jobs wait without any consumption of CPU for a lock to be released.
