Agent start script executes a shell script to kill running tasks in case of a JobScheduler Agent crash

Feature

• In case of a JobScheduler Agent crash, the Agent start script kills any running tasks.
• The start script starts the Agent with a watchdog process. The watchdog process waits for termination of the Agent. Once the Agent terminated abnormal then the script ./bin/jobscheduler_agent_kill_task.(sh|cmd) is executed by the watchdog process for each running task.

Implementation

• Kill Running Tasks
  • The Agent provides the command to execute the kill script for each running task with the file kill_tasks_after_crash_<port>.(sh|cmd) in the logs folder, see JS-1551.
  • Before start of an Agent the Agent start script removes an existing file with this name.
  • The Agent start script starts the Agent with a watchdog process which waits for termination of the Agent.
  • After an abnormal termination of an Agent the watchdog process executes this file should the file be available and should any lines with commands be contained in this file.
• Agent Kill Script
  • The script is parameterized as explained with JS-1551
  • The Agent kill script will log the information from its parameters to the log file agent_kill_task_<port>.log in the logs directory.
