Migration of the Oracle Data Miner repository arises in the following cases:
A version of SQL Developer before 4.0 is installed on Oracle Database 11g Release 2 (11.2.0.4) or later, and you want to connect using a SQL Developer 4.0 or later client, that is, you upgrade the client.
SQL Developer 4.0 installed on a version of Oracle Database 11g Release 2 (11.2.0.3) or earlier, and the database is upgraded to Oracle Database 11g Release 2 (11.2.0.4) or later.
Either of these conditions is detected when you open the connection in the Data Miner Navigator. If the ODMRSYS default permanent tablespace is not an ASM tablespace, then a dialog is displayed requesting an ASM tablespace. The ASM tablespace does not replace the existing default permanent tablespace already specified for ODMRSYS, but instead, it converts the workflow_data column that stores the workflow XML data in the ODMR$_WORKFLOWS table. The workflow_data is usually the largest data component stored in ODMRSYS. This approach reduces the amount of time required to perform the migration.
The Repository Migration does not request temporary tablespace.
