General

  • Data Migrator is now compatible with docker.
  • Data Migrator allows to use AWS Secrets Manager to retrieve connection details (see database identification).

Improvements

We introduced new properties:

  • sqlmodel.path to specify a custom location for SQLMODEL.json file.
  • ignoreDeletedRecords: in mainframe data files, deleted records are filled with blank characters, leading to an exception when Data Migrator reads a blank numeric field. It is now possible to configure Data Migrator, with this new property set to true, to ignore record starting with blanks.
  • dataBaseDriverPath to provide the location of the database drivers’s folder anywhere in the system/computer.
  • dataBaseServiceName to add the possibility of a connection to an Oracle database using a service name. This property is not compatible with dataBaseName property.
  • convertGraphicDataToFullWidth: By default, SQL graphic data is coded on two bytes. When it is not the case, this property needs to be set to true.
  • dataBaseCustomConnectionUrl allows the customer to provide a full custom connection URL to the database.


See Mirations Steps for more details.
