It can take too long for TPFDF to respond to the CDC clients query request of such a large database. SOLUTION: B+Tree indexing has been added to the CDC TPFDF detail file. This allows for improved response time when querying data. COREQS: None. MIGRATION CONSIDERATIONS: Existing CDC TPFDF databases cannot be migrated to using the updated DBDEF. It will require the initialization (ZUDFM INIT FCA0) of the FCA0 file. This affects all TPF LPAR's within a loosely coupled complex.
