Basics
A Proxy object is the representant of an Ubik object (instance) for one Interface.
One Proxy object can handle both import and export of the same Ubik instance via one interface.
The Proxy object has a "normal" Property for every MetaProperty defined on its MetaProxy.
The Proxy object has a Proxy Property for every ProxyMetaProperty defined on its MetaProxy (via the Relation "SYSREL_METAPROXY_PROPERTY").
Value Tracking
Every Proxy properties supports access to multiple data of the same data field:
- Current value in Ubik
- Timestamp of the current value
- Exported value
- Timestamp of the export
- Import value
- Timestamp of the import
Current Value
- Current value stored on the object in the system
- Timestamp the value was set. If it is the initial value, the timestamp is equal to the CTS of the object
The current value is stored on the original UBIK object.
Exported Value
- Value that was exported (and commited) via an export interface run
- Timestamp the value was exported. This is the timestamp when the export of the object was triggered
The exported value is stored on the proxy object.
Imported Value
- Value that was imported via an import interface run
- Timestamp the value was imported. This is the timestamp when the import of the object was triggered
The imported value is stored on the proxy object.
Interface States
Every proxy objects supports two interface states:
- Export state
- Import state
Export states
| Property | Description |
|---|---|
| Completed | The object is exported, the external system has confirmed |
| Queued for export | The object is marked for an data update from the ubik instance to the proxy , but the export was not executed yet |
| Queued for external processing | The proxy was updated recently (by exporting ubik data to the proxy) but was not processed via an data export to the external system |
| Handshaking | The object was exported, but the confirmation was not received yet |
| Conflict | There is an export conflict |
| Error | An error occured during the last export |
| Undefined | Status of proxy is undefined |
Import states
| Property | Description |
|---|---|
| Proxy updated | The object was successfully updated from the external system |
| Queued for import | The object is marked for an import, but the import was not executed yet |
| Handshaking | The object was imported, but the handshake answer was not sent yet |
| Conflict | There is an importconflict |
| Error | Error occurred during the last import |
| Undefined | Status of proxy is undefined |
Timestamp information
CTS
Point of time when the Proxy instance was initially created.
UTS
Last point of time when the Proxy instance was updated.
Export TS
Last point of time when the Proxy instance was updated with export data (updated with data from the linked UBIK instance)
External Export TS
Last point of time when the data from the proxy was exported to a 3rd party system.
Import TS
Last point of time when the data of the Proxy instance was imported (forwarded the data to the linked UBIK instance)
External Import TS
Last point of time when the data from the proxy was imported from a 3rd party system.
