Backward compatibility

For the 6.0.2 version of the WebSphere® Adapter for Flat Files, significant changes have been made to the business object structure in order to add greater functionality to the adapter. Backward compatibility is supported in the 6.0.2 version of the Adapter for Flat Files. The older business object structures and service descriptions supported in the previous version of the adapter are backward compatible with the 6.0.2 version of the Adapter for Flat Files.

In order to provide backward compatibility, the Adapter for Flat Files supports two activation specifications. The FlatFileActivationSpec supports the 6.0.0 version of the adapter while the FlatFileActivationSpecWithXid supports the 6.0.2 version of the adapter.

Some of the properties that are exclusive to the 6.0.0 version of the adapter are not applicable to the 6.0.2 version of the adapter. There is no scenario to run the enterprise service discovery wizard for the older 6.0.0 properties and whenever the enterprise service discovery wizard is run for the inbound application, it is with respect to only 6.0.2 attributes. 6.0.2 features are not available unless the user decides to run the enterprise service discovery wizard to generate new activation specifications, managed connection factories, and interaction specifications.
Note: To upgrade from a version 6.0.0 RAR to a 6.0.2 RAR adapter file, you must use WebSphere Integration Developer, Version 6.0.1.2. Otherwise you may be unable to view the Binding properties in the Properties Tab of WebSphere Integration Developer in the Business Integration perspective.
The inbound properties that are exclusive to 6.0.0 version of the adapter are the following:
  • FFEventTableName
  • FFDatabaseName
  • FileSplitThreshold
  • FileChunkSize
  • AutocreateEDT
  • EDTDatabaseName
  • EDTDriverName
  • EDTTableName
  • EDTUserName
  • EDTUserPassword

For outbound processing, the OutputFileName property has been introduced in the 6.0.2 version of the adapter in order to provide backward compatibility for the 6.0.0 version of the adapter. This property will be available when you use the enterprise service discovery wizard for outbound processing.

Note: All pending inbound and outbound operations should be completed by the 6.0.0 version of the Adapter for Flat Files before performing the upgrade procedure. In addition, all event producing applications must be stopped before performing the upgrade procedure.
