Storage Configuration for Oracle Data Miner

The storage format used by Oracle Data Miner depends on the version of the database:

The Oracle Database versions and the corresponding storage format used by Oracle Data Miner are:

  • With Oracle Database 11.2.0.1 - 11.2.0.3, Oracle Data Miner uses object-relational storage.

    Approximately 200MB - 700MB XML DB object-relational storage is required.

  • With Oracle Database 11.2.0.4 and later, Oracle Data Miner uses binary XML storage.

    With binary storage, a tablespace allocation of 200MB can store approximately 1000 moderately complex workflows (about 35 nodes).

    To use binary storage, ODMRSYS must be created in a tablespace managed with Automatic Segment Space Management (ASSM).

    The following statement shows how to create an Oracle ASSM tablespace:

    CREATE TABLESPACE DMUSER_AUTO DATAFILE 'DMUSER_AUTO.dat' size 20m 
         autoextend on next 32m maxsize UNLIMITED extent management local
         AUTOALLOCATE SEGMENT SPACE MANAGEMENT AUTO;
