Name:

• tunable

Description:

• This action program is run whenever a tunable operating system parameter is in danger of being exhausted. To ensure that the system does not completely run out of resources, it reconfigures the operating system kernel to increase resource allocation.
  • For SCO Release 3 systems, the increased resource allocation will not take effect until the operating system is rebooted.

  • For SCO OpenServer Release 5, some tunable parameters can be adjusted without the need for a system reboot. The alert notice will indicate if a reboot is necessary.

• The relevant tunable parameter will be increased by the proportion specified by the increase keyword. To prevent continual re-configuration of the operating system that may occur if resource depletion is being caused by a poorly designed application, the times keyword specifies a maximum number of times that the system will be reconfigured. The sofar keyword stores the number of reconfigures thus far. If the times value is reached, it may be reset.

• If the approval keyword is set to true, the required reconfiguration command will be sent to the administrator for approval.
