B Back-end Adapter Data Type Support

OracleAS Adapter for IMS/TM supports several 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 OracleAS Adapter for IMS/TM and Oracle Application Server is performed internally by Oracle Connect.

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.
