Limiting vxdbd resource usage
Although the vxdbd daemon is light-weight in terms of resource usage, system administrators might want to additionally restrict its resource usage. This can be controlled by using two configuration parameters in /etc/vx/vxdbed/admin.properties:
MAX_CONNECTIONS: This parameter controls the maximum number of simultaneous requests that vxdbd should allow.
MAX_REQUEST_SIZE: This parameter controls the maximum size of a single request (in bytes).
Setting these parameters too low may cause SFDB commands to fail. The following are the suggested minimum values for these parameters:
MAX_CONNECTIONS: 5
MAX_REQUEST_SIZE: 1048576 (1 MB)
Note:
Restart vxdbd after making any changes to these parameters for the changes to take effect.
