  • ID: Task ID
  • UKT: Number of the user kernel thread
  • Unix tid/Win tid: Unix/Windows thread ID of the user kernel thread
  • Type: Type of the task. (Timer, Log Writer, Trace Writer, Utility, Pager (Data Writer), Server Task, User Task, Garbage Collector).
  • APPL pid: Process ID of the application program linked to the task. An asterisk (*) after the pid indicates that the process ID is on a separate computer and is being accessed remotely. The number, 0, in pid field indicates a java process.
  • Current state: Current state of the task. An ampersand (&) after the state means that the task is in a COM routine which is called from liveCache kernel. An asterisk (*) in the current state means that the task is in the run queue meaning it is ready to run but it is waiting for other tasks to yield the CPU. An exclaimation mark (!) after the state means that the issued command is already cancelled. The user might have killed the process. The numbers after the state indicates the name of the item it is waiting for.
  • Timeout priority: If the task is in a state pending a timeout, for example, vwait, the seconds until the end of the timeout are shown in this column.
  • Region cnt: Count that a critical region has been accessed since the task has been running.
  • Region try: Number of the queried or held critical region that the task is waiting for because that specific region is locked by another task.
  • Wait item: The item the task is waiting for. It depends on the wait situation. If a task is waiting for an exclusive lock on a critical section (region or reader-writer lock), the "wait item" displays the region number the task would like to lock. If a task is waiting for an B*Root lock ( InvRootExcl, TabRootExcl, InvRootShare, TabRootShare), the "wait item" displays the root page number of the tree it is waiting for. If a task is waiting for a page lock (InvNodeExcl, TabNodeExcl, InvNodeShare, TabNodeShare), the "wait item" displays the page number it is waiting for.
