tfactl setresourcelimit

Use the tfactl setresourcelimit command to restrict the CPU and memory usage of Oracle Trace File Analyzer.

Note:

The tfactl setresourcelimit command has been deprecated in 21.1. Oracle recommends using ahfctl setresourcelimit instead.

Syntax

tfactl setresourcelimit
[-tool tool_name]
[-resource resource_type]
[-value value]

Parameters

tfactl setresourcelimit Command Parameters

Parameter	Description
value	Set the limit to a minimum of 50% of a single CPU, and a maximum of 4 or 75% of the available CPUs, whichever is lower. By default, the CPU limit is set to the maximum. To limit TFA to a maximum of 50% of a single CPU: tfactl setresourcelimit -value 0.5 You can limit memory usage either at the system level using tfactl setresourcelimit -resource kmem or combined system and swap memory using tfactl setresourcelimit -resource swmem.
tool	Currently, you can only specify tfa. Default: tfa
resource	You can specify either CPU or memory.

Examples setresourcelimit

On a server with 10 CPUs, the default limit will be 4 CPUs:

# tfactl setresourcelimit
Tool TFA: Resource CPU: Limit value: 4

On a server with 4 CPUs, the default limit will be 3 CPUs (75% of available CPUs):

tfactl setresourcelimit
Tool TFA: Resource CPU: Limit value: 3

# tfactl setresourcelimit -value 2
Tool TFA: Resource CPU: Limit value: 2

To limit the memory usage to only 1 GB of system memory run:

tfactl setresourcelimit -resource kmem -value 1024

To limit the combined total of system memory and the swap memory to 2 GB run:

tfactl setresourcelimit -resource swmem -value 2048
