Configuring the execution period for agent functions
An agent function is allocated an execution period using the respective time-out attributes: OnlineTimeout, OfflineTimeout, MonitorTimeout, and CleanTimeout. By default these values are set to 300, 300, 60 and 60 respectively.
If an agent function executes a program, for example sapcontrol.exe, the program must execute within the allocated execution period. If the program is unable to execute within the allocated period, the agent function cancels and terminates the execution of the program. You must set these timeout attributes to appropriate values depending on the time required for SAP applications. You can modify these values with the following command.
hatype -modify TypeName attribute_name attribute_value
Example: C:\> hatype -modify SAPWebAS OnlineTimeout 600
