Oracle 7 support in KCML 5
KCML5 had experimental support for the Oracle version 7 Call Interface. Though Oracle deprecated support for this OCI with Oracle 8, it continued to ship unsupported with later versions of Oracle.
KCML 6 now supports the current Oracle OCI with Oracle 10g and later in an improved implementation that supports the full KDB functionality. Like the KDB implementation, this Oracle implementation uses a catalog.
KCML can still use the old OCI by connecting to a database type of "ORACLE7" in KI_CONNECT.
To transition to the new Oracle support you will need to build a new style catalog by adding the tables to the catalog with ALTER CATALOG ADD TABLE statements.
