Model States

Models can have one of the following states or specific combinations of those:

• ACTIVE
• ALIVE
• DISABLED
• INACTIVE
• VALID

The following combinations are possible:

• active and alive
• disabled and active
• disabled and inactive

Active

Models that the engine will use for starting new processes are in ACTIVE state. This state is determined by checking the validity (valid from / valid to), the disabled flag and/or priority setting.

Alive

All models that are in ACTIVE state and which have running processes, have the state ALIVE.

Disabled

If model processes are marked as disabled (suspended), the model has the state DISABLED. Note that a model marked as disabled might still be alive.

Inactive

Models that are not in ALIVE state, which means they are not active and have no running processes, are in INACTIVE state.

Valid

The VALID state is determined by checking the validity (valid from / valid to), the disabled flag and/or priority setting.
