Parameters

attract strength: Specifies a positive affinity in the range of 1 to 100000. The higher the value, the stronger the preference for all the instances of the current process to run on the same location.

default: Sets the affinity to the default, a positive affinity of 200.

none: Sets the affinity to 0, which means the instances of the process have no preference to run on the same location and the system determines their locations.

repulse strength: Sets a negative affinity in the range of 1 to 100000. The higher the value, the weaker the preference for all the instances of the current process to run on the same location.

Usage guidelines

This command sets the preference for a process to run all its instances on the same location or different locations. If the process has only one instance, the command does not take effect.

The self affinity in the placement process view of a process and any of its instances overwrite each other, and whichever is configured the last takes effect on all the instances of the process.

To view the instances of a process, use the display placement program all command.

Examples

# Configure a negative self affinity of 200 for BGP.

<Sysname> system-view
[Sysname] placement program bgp
[Sysname-program-bgp] affinity self repulse 200
