A realtime administrator can change the behavior of the realtime portion of the scheduler by reconfiguring the config_rt_dptbl at any time. One method is described in rt_dptbl(4) in the section titled "REPLACING THE RT_DPTBL LOADABLE MODULE".
A second method for examining or modifying the realtime parameter table on a running system is through using the dispadmin(1M) command. Invoking dispadmin(1M) for the realtime class allows retrieval of the current rt_quantum values in the current config_rt_dptbl configuration from the kernel's in-core table. When overwriting the current in-core table, the configuration file used for input to dispadmin(1M)dispadmin must conform to the specific format described in rt_dptbl(4).
Following is an example of prioritized processes rtdpent_t with their associated time quantum config_rt_dptbl[] value as they might appear in config_rt_dptbl[].
