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

The definition for state ACTIVE is the following:

• For each model ID, there are either zero or one active model version
• The model with the most recent deployment date that has validTo and validFrom dates compatible with the current date is the active model for any given model ID

New processes instances can be started only for active models.

Alive

Any deployed model that either has running instances or is in ACTIVE state is called Alive

For a given model ID, there can be an arbitrary number [0,...N] of alive model versions.

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.
