Oracle DB2
Instance Instance
Redo logs Logs files
Statement cache Package cache
Datafiles DMS containers
Data cache Buffer pools
Data dictionary System catalog
Datafiles Containers
Segments Objects
Data blocks Pages
Database Link Federated System

And also, some useful mapping between Oracle and DB2 products:

Oracle DB2
Oracle EE DB2 Entreprise
Oracle Gateway DB2 Connect
SQL *PLUS DB2 CLP / DB2 CLP PLUS
PL/SQL SQL Procedural Language

You should also take care of the “package” term. For Oracle it’s a logical grouping of PL/SQL blocks that can be invoked by other PL/SQL applications, and for DB2 it’s a precompiled access plan for an embedded static SQL application stored in the server.
