Table
Description
DLV_SUBSCRIPTION This table stores delivery subscriptions for an in-
stance. Whenever an instance expects a message
from a partner (for example, the receive or
onMessage activity) a subscription is written out for
that specific receive activity.
DOCUMENT_CI_REF
This table stores cube instance references to data
stored in the XML_DOCUMENT table.
INSTANCE_PAYLOAD All asynchronous invocation messages are stored in
this table before being dispatched to the engine. It
stores incoming invocation messages (messages that
result in the creation of an instance). This table only
stores the metadata for a message that invokes a
composite instance.
WORK_ITEM
This table stores information related to activities cre-
ated by an instance. All process activities in a flow will
have a column in the WORK_ITEM table created for it.
This WORK_ITEM column contains metadata for the
activity such as current state, label, expiration date
(used by wait activities), etc. When the engine needs
to be restarted and instances recovered, pending
flows are resumed by inspecting their unfinished work
items.
