3.3.3 Notes

  1. A comment specified in a control statement must be enclosed between /* and */.
  2. When specifying the define system and the create rdarea statements at the same time, specify the define system statement first.
  3. The following table shows the specification order and the permitted numbers of create rdarea statements:
    Specification order RDAREA type Number of statements
    1 Statement for master directory RDAREA 1
    2 Statement for data directory RDAREA 1
    3 Statements for data dictionary RDAREAs 1 to number of data dictionary tables*
    4 Statements for data dictionary LOB RDAREAs 0 or 2
    5 Statements for user RDAREAs, user LOB RDAREAs, and list RDAREAs Any number

Note 1
Check that the number of RDAREAs does not exceed the maximum permissible number of RDAREAs, as specified in the system common definition (value of pd_max_rdarea_no). Also check that the number of HiRDB files that constitute the RDAREAs do not exceeds the maximum permissible number of HiRDB files that can constitute RDAREAs (value of pd_max_file_no).

Note 2
A created shared RDAREA is counted as if it has been created at every back-end server. Therefore, if the number of RDAREAs or the number of HiRDB files constituting the RDAREAs exceeds the permitted maximum value at any back-end server, the shared RDAREA cannot be created.

* When there are data dictionary RDAREAs for which of routines is specified, the maximum number of data dictionary RDAREAs that can be specified is (number of data dictionary tables - 2).
