Data model

Table message

Table for storing asynchronous messages:

Attribute	Type	NULL	Description	Value description
msg_id	number	No	Unique identifier, primary key.	Automatically generated.
msg_timestamp	datetime	No	Message timestamp, generated by source system. This timestamp determines processing order of messages.	Source system, part of TraceHeader TraceHeaderProcessor.TRACE_HEADER
receive_timestamp	datetime	No	Timestamp when message arrives to integration platform, generated by OpenHub.	Automatically generated when input request arrives.
service_name	string	No	Service name, e.g. customer Implements org.openhubframework.openhub.core.entity.ServiceExtEnum interface	Source system AsynchConstants.SERVICE_HEADER
operation_name	string	No	Operation name, e.g. createCustomer	Source system AsynchConstants.OPERATION_HEADER
object_id	string	Yes	Object ID that is impacted by processing of this message. For example when this message updates customer object then it can be customer ID. This values serves for searching messages which impact identical object. When there are two messages in processing queue, both want to change identical object, then first message will be skipped and second one will be processed.	AsynchConstants.OBJECT_ID_HEADER
entity_type	string (enum)	Yes	Entity type (implements org.openhubframework.openhub.api.entity.EntityTypeExtEnum interface). In general it's enough to detect identical changed data by objectId and operation name but there are few different operations which can change the same data (e.g. setCustomer, setCustomerExt). If defined then it will be used for "obsolete operation call" detection instead of operation name.	AsynchConstants.ENTITY_TYPE_HEADER
correlation_id	string	No	ID generated by source system that is important for pairing request and asynchronous response in source system. Combination correlation_id and source_system is unique.	Source system, part of TraceHeader TraceHeaderProcessor.TRACE_HEADER
process_id	string	Yes	Process identifier serves for pairing messages of same process.	Source system, part of TraceHeader TraceHeaderProcessor.TRACE_HEADER
payload	string (XML)	No	Message payload
envelope	string (XML)	No	The whole input request, e.g. SOAP envelope including headers and body
source_system	string (enum)	No	Source system (implements org.openhubframework.openhub.core.entity.ExternalSystemExtEnum interface)	Source system, part of TraceHeader (applicationID) TraceHeaderProcessor.TRACE_HEADER
state	string (enum)	No	Message state (enum value: NEW: new saved message IN_QUEUE: message is in SEDA queue and waiting for free thread for processing PROCESSING: message is being processed OK: successfully processed message PARTLY_FAILED: last processing ended with error, there will be next try FAILED: finally failed message, no next processing WAITING: parent message that waits for child messages WAITING_FOR_RES: message that waits for confirmation/response from external system CANCEL: message was canceled by external system or by administrator. This state isn't set by this application. POSTPONED: message is postponed because there was another message that was processed at the same time with same funnel values.
failed_count	number	No	Count of unsuccessful tries. Default value is 0.
failed_error_code	string	Yes	Error code when message processing failed (implements org.openhubframework.openhub.core.common.exceptions.ErrorExtEnum interface)
failed_desc	string	Yes	Error description when message processing failed.
last_process_timestamp	datetime	Yes	Timestamp when this message was lasttime updated.
start_in_queue_timestamp	datetime	Yes	Timestamp when this message was lasttime changed to state IN_QUEUE.
custom_data	string	Yes	Field for saving custom data, suitable for sharing information between more tries of processing.
parent_msg_id	number	Yes	Reference to parent message (parent-child binding).	Useful for parent-child binding, ChildMessage#createMessage
parent_binding_type	string (SOFT)	Yes	Binding type defines how tightly child message does influence parent message: HARD: result of child message influences result of parent message (for example when child message ends in FAILED state then parent message will in FAILED state too) SOFT: result of child message has no effect to parent message Useful for parent-child binding only, see asynch-child component.	Useful for parent-child binding, ChildMessage#createMessage
funnel_value	string	Yes	Funnel value is for finding out if two or more concurrent messages impact identical target object. Funnel value can be anything, e.g. customer ID, subscriber mobile number, custom string etc. This value is for msg-funnel component use.	AsynchConstants.FUNNEL_VALUE_HEADER
funnel_component_id	string	Yes	Funnel identifier that specifies unique point during message processing. Messages are checked and filtered out to this point. This value is for msg-funnel component use.	Useful for msg-funnel component.
guaranteed_order	boolean (false)	No	When this flag is true then mesage is processed in guaranteed order.	AsynchConstants.GUARANTEED_ORDER_HEADER
exclude_failed_state	boolean (false)	No	Messages in FAILED state are taking into consideration for guaranteed order by default. If FAILED state should be excluded then this flag will be true. Value of this attribute has sense only when guaranteed_order is true.	AsynchConstants.EXCLUDE_FAILED_HEADER
node_id	number	No	Reference to cluster node, see Node table below

Table external_call

Table stores calls to external systems when extcall component is used.

Attribute	Type	NULL	Description
call_id	number	No	Unique identifier, primary key.
msg_id	number	No	Reference to asynchronous message.
operation_name	string	No	Operation name.
state	string (enum)	No	External call state: PROCESSING: external call is just processing OK: external call is successfully done FAILED: external call failed, try it next time FAILED_END: all confirmation tries failed, no further processing
entity_id	string	No	Entity identifier
msg_timestamp	datetime	No	Message timestamp (from source system).
creation_timestamp	datetime	No	Timestamp when this record was created.
last_update_timestamp	datetime	No	Timestamp when this record was lasttime updated.
failed_count	number	No	Count of unsuccessful external calls.

Tables request and response

These tables stores requests/responses in communication with external systems.

Attribute	Type	NULL	Description
req_id	number	No	Unique request identifier, primary key.
msg_id	number	Yes	Binding to asynchronous message (NULL for synchronous messages).
res_join_id	string	Yes	Identifier for pairing/joining request and response together. It can be Message or correlation ID or exchange ID or some ID that is unique with uri. This attribute helps to associate response to the right request.
uri	string	No	Endpoint/target URI
req_envelope	text	No	The request content
req_timestamp	datetime	No	Timestamp when request was send to target URI.

Unique key: uri and res_join_id

Attribute	Type	NULL	Default	Description
res_id	number	No		Unique response identifier, primary key.
req_id	number	Yes		Binding to corresponding request to this response.
res_envelope	text	Yes		The response itself. If not specified then failed reason must be filled.
failed_reason	string	Yes		Reason (SOAP fault, exception, stackTrace, ...) why communication failed.
res_timestamp	datetime	No		Timestamp when response/failed reason was received back.
failed	boolean	No	false	Has been communication failed? If yes then failed reason must be filled.
msg_id	number	Yes		Binding to asynchronous message (NULL for synchronous messages).

Table configuration

Table stores default configuration parameters. See External configuration model for more details.

Attribute	Type	NULL	Default	Description
code	number	No		unique code of one configuration item, e.g. ohf.asyncThread.processing.count.name
category_code	string	No		unique code for specific configuration scope, e.g. "dataSource" for data source settings
current_value	string	Yes		current (valid) value
default_value	string	Yes		default value if there is no current_value defined
data_type	string	No		data type of current and default value
mandatory	boolean	No	true	is this configuration item mandatory? In other worlds must be at least one current or default value defined?

Table node

Table stores evidence of cluster nodes. See Nodes evidence for more details.

Attribute	Type	NULL	Default	Description
node_id	number	No		primary key, technical identifier
code	string	No	value ohf.cluster.actualNodeInstance.code property	unique node code

description	string	Yes		Node description
state	string	No		Node's state: RUN: Node handles new and existing (saved messages in ESB) messages HANDLES_EXISTING_MESSAGES: Node handles only existing messages. New messages/requests are rejected. Used is Stopping mode. STOPPED: Node not handles existing messages and new messages.
