• The JS7 offers to perform operations on Controllers and Agents by the JS7 - REST Web Service API.
  
  • For detailed information see the Technical Documentation of the REST Web Service API.
  • For available CLI operations see JS7 - Unix Shell Command Line Interface.
• The REST Web Service API can be accessed from Shell utilities such as curl.
• In addition, a PowerShell module is available for simplified access to the REST Web Service API. This is described in the JS7 - PowerShell Module article.

commands commands

Commands

• terminate
  • Allows to terminate a Controller instance. If a Controller Cluster is used then no fail-over will occur as normal termination is not considered a failure situation.
  • When used with the active Controller instance in a Controller Cluster, users can apply the --switch-over switch to shift the active role on termination of the active cluster member. After restart the Controller instance will take the standby role in a Controller Cluster.
  • In a Controller Cluster the command will terminate the Controller instance identified by its URL using the --controller-url option.
• restart
  • Allows to restart a Controller instance. If a Controller Cluster is used then no fail-over will occur as normal termination is not considered a failure situation. The --switch-over switch can be used similarly to the terminate command.
  • In a Controller Cluster the command will restart the Controller instance identified by its URL using the --controller-url option.
• cancel
  
  • Allows to cancel a Controller instance. The Controller will immediately disconnect from Agents, will not create a journal snapshot and will terminate.
  • The command will cause fail-over in a Controller Cluster if used with the active Controller instance. After restart the Controller instance will take the standby role in a Controller Cluster.
  • In a Controller Cluster the command will cancel the Controller instance identified by its URL using the --controller-url option.
• cancel-restart
  • The command combines the operations to cancel and to restart a Controller instance.
• switch-over
  • The command allows to shift the active role in a Controller Cluster. For switch-over the Primary and Secondary Controller instance must be coupled.
• appoint-nodes

  • The command can be used in case that a Controller Cluster will not be coupled on initial operation.

  • The command is automatically sent by JOC Cockpit to Controller instances after restart.
• confirm-loss
  • The command can be used in a situation when the active JOC Cockpit Cluster Watch was not witness to failure of the active Controller Cluster member.
  • Users can confirm that the failed Controller Cluster member effectively is not running which allows the remaining Controller Cluster member to take the active role.
• check
  • Tests the connection between JOC Cockpit and a Controller instance.
  • The --controller-url option must be specified that will be used from JOC Cockpit to connect to the Controller. 
• enable-agent

  • Agents can be enabled after having been disabled. Enabled Agents are considered for job execution.

• disable-agent
  • When Agents are disabled, they are not considered for job execution. Running jobs can continue until completion.
• reset-agent

  • When an Agent is reset then the Agent will terminate and will restart. Job processes running in the Agent will be forcibly terminated and orders will be set to the failed state. When a forced reset is performed, then the operation forces an Agent to be reinitialized, to drop its journal and to be dedicated to the current Controller. Users are recommended to double-check if an Agent is not dedicated to a different Controller before using the --force switch.

• switch-over-agent

  • Allows to switch-over the active role between Director Agents in an Agent Cluster. For switch-over the Primary and Secondary Director instance must be coupled.

• confirm-loss-agent

  • The command can be used in a situation when the active Controller Cluster Watch was not witness to failure of the active Director Agent in an Agent Cluster. Users can confirm that the failed Director Agent effectively is not running which allows the remaining Director Agent member to take the active role.

• enable-subagent
  • Subagents can be enabled after having been disabled. Enabled Subgents are considered for job execution.
• disable-subagent
  • When Subgents are disabled, they are not considered for job execution. Running jobs can continue until completion. 
• reset-subagent
  • When a Subagent is reset then the Subagent will terminate and will restart. Job processes running in the Subagent will be forcibly terminated and orders will be set to the failed state. When a forced reset is performed, then the operation forces a Subagent to be reinitialized and to be dedicated to the current Agent Cluster. Users are recommended to double-check if a Subagent is not dedicated to a different Agent Cluster before using the --force switch.
• encrypt
  • Allows to encrypt a value using the --in option. If used to encrypt a file then --infile and --outfile options must be specified.
  • The --cert option specifies the path to a file holding the Certificate used for encryption.
  • Encryption is performed by Java libraries that are looked up in the ./lib sub-directory of the JS7 Unix Shell CLI. For details see JS7 - Encryption and Decryption.
• decrypt
  • Allows to decrypt a value using the --in option. If used to decrypt a file then --infile and --outfile options must be specified.
  • The --key option specifies the path to the Private Key used for decryption. If the Private Key is protected by a password, then the --key-password option or switch must be specified.
  • Decryption is performed by Java libraries that are looked up in the ./lib sub-directory of the JS7 Unix Shell CLI.

• terminate
  • Allows to export objects such as workflows to an archive file in .zip or .tar.gz format. The command comes in two flavors:
    • export individual objects specified by the --path and --type options.
      • Should relative paths be used in the archive file then the --start-folder option and --use-short-path switch can be applied.
    • export objects from folders using the --folder option and --recursive switch.
      • Optionally one or more object types can be specified and otherwise all objects will be exported, see --type option.
      • Should relative paths be used in the archive file then the  --use-short-path switch can be applied.
      • Export of objects can further be limited by use of the --no-* switches, see section Switches.
  • The archive file is specified from the --file and --format options.
  • If JOC Cockpit is operated for the High Security Level then the --for-signing switch can be used to export Controller Objects that should be digitally signed. Objects and signatures can be imported using the import-deploy command.
• restart
  • Imports an archive file to the inventory. The operation applies to use of JOC Cockpit with the Low and Medium Security Level.
  • Users can specify if existing objects will be overwritten or if duplicate objects from the import file will be assigned a prefix or suffix or will be ignored.
• cancel
  
  • Imports an archive file to the inventory and deploys the included objects. The operation is applicable if JOC Cockpit is operated for the High Security Level.
    • As a prerequisite the archive file must be exported using the --for-signing switch.
    • Workflows and Job Resources from the archive file are digitally signed by the user. Signature files are added to the archive file.
  • On import the objects in the archive file are deployed to related Controllers as specified during export.
• cancel-restart
  • Allows to deploy Controller Objects such as workflows. The command can be used in two flavors:
    • deploy individual objects specified by the --path and --type options.

Switching-over, Appointing Nodes and Confirming Node Loss for Controller Cluster

Users can switch-over the active role in a Controller Cluster. This is achieved by use of the switch-over command and implicitly by use of the --switch-over option with the terminate and restart commands.

The appoint-nodes command is available in case that a Controller Cluster will not be coupled on initial operation.

# confirm node loss for Controller Cluster
./operate-controller.sh confirm-loss "${request_options[@]}" 

Enabling, Disabling, Resetting Agents

When Agents are disabled, they are not considered for job execution. 

When an Agent is reset then the Agent will terminate and will restart. Users are recommended to double-check if an Agent is not dedicated to a different Controller before using the --force switchThe confirm-loss command can be used in a situation when the active JOC Cockpit Cluster Watch was not available at the point in time of failure of the active Controller Cluster member. Users can confirm that the failed Controller Cluster member effectively is not running which allows the remaining Controller Cluster member to take the active role.

For an Agent Cluster the reset-agent command is available. Enabling/disabling is performed at Subagent level.

When resetting an Agent Cluster then similar behavior applies as for Standalone Agents. Users should be aware that all Subagents in an Agent Cluster will be reset.

Switching-over and Confirming Node Loss for Agent Cluster

Users can switch-over the active role in an Agent Cluster.

The confirm-loss-agent command can be used in a situation when the active Controller Cluster Watch was not witness to failure of the active Director Agent in an Agent ClusterWhen an Agent is reset then the Agent will terminate and will restart. Job processes running in the Agent will be forcibly terminated and orders will be set to the failed state. When a forced reset is performed, then the operation forces an Agent to be reiniitalized, to drop its journal and to be dedicated to the current Controller. Users are recommended to double-check if an Agent is not dedicated to a different Controller before using the --force switch.

# common options for connection to JS7 REST API

For an Agent Cluster the reset-agent command is available. Enabling/disabling is performed at Suagent level.

Encrypting and Decrypting

• Secrets can be encrypted and decrypted as explaind with JS7 - Encryption and Decryption.
• Encryption/decryption require related Java libraries that are available from the ./lib sub-directory.
• For creation of a Private Key and Certificate see JS7 - How to create X.509 Encryption Keys.
