B IMS/DB Back-end Adapter Data Type Support

OracleAS Adapter for IMS/DB supports a number of data types that are used when defining metadata in Oracle Studio. The data types are mapped from the COBOL data types during the import procedure.


Note:

The mapping of data types between Oracle Application Server Adapter for IMS/DB and Oracle Application Server is performed internally by Oracle Connect.

This appendix contains the following section:

Data Type Mapping

The COBOL data type COMP, in the table is an abbreviation for, and synonymous with, COMPUTATIONAL. Square brackets ([ ]) denote optional qualifiers for some COBOL compilers, which may not be allowed for other COBOL compilers.
