The Data Dictionary supports updating (set/reset) defaults area for table/index/lob. from DB properties dialog box (only in GUI). For more information, see Show default areas for creating database objects in Manage the OpenEdge Database.

You can load objects into default areas using a data definition file (.df). For example, this sample file loads tables, lobs, and indexes into default areas.

ADD TABLE "tab1"
  AREA "Table Area"
  DUMP-NAME "tab1"

ADD FIELD "id" OF "tab1" AS integer 
  FORMAT "->,>>>,>>9"
  INITIAL "0"
  POSITION 2
  MAX-WIDTH 4
  ORDER 10
  MANDATORY

ADD FIELD "name" OF "tab1" AS character 
  FORMAT "x(8)"
  INITIAL ""
  POSITION 3
  MAX-WIDTH 16
  ORDER 20

ADD FIELD "clob1" OF "tab1" AS clob 
  FORMAT "x(8)"
  INITIAL ?
  POSITION 4
  LOB-AREA "Lob Area"
  LOB-BYTES 104857600
  LOB-SIZE 100M
  CLOB-CODEPAGE "iso8859-1"
  CLOB-COLLATION "basic"
  CLOB-TYPE 1
  ORDER 30

ADD FIELD "blob1" OF "tab1" AS blob 
  FORMAT "x(8)"
  INITIAL ?
  POSITION 5
  LOB-AREA "Lob Area"
  LOB-BYTES 104857600
  LOB-SIZE 100M
  ORDER 40

ADD INDEX "idx1" ON "tab1" 
  AREA "Index Area"
  PRIMARY
  INDEX-FIELD "id" ASCENDING

Note: If .df is generated with previous OpenEdge version that did not support default areas, but loaded with a version that supports them, database objects will load into default areas. When the default area is not set and area is not mentioned in .df file, then tables and indexes are assigned to schema area and LOB field assigned to the table’s area.
