Question

ADDI identifies that a VSAM KSDS is accessed by 12 COBOL programs. What modernization implication does this raise?

Accepted Answer

The VSAM file should be converted to a sequential flat file to reduce the number of dependent programs — Think of it like working hands-on with IBM mainframe systems — the answer here is 'The VSAM file should be converted to a sequential flat file to reduce the number of dependent programs'. A VSAM file accessed by 12 programs is a shared data store that needs holistic treatment: it may become a relational table or a data service so all migrated modules access data consistently. On real mainframe exams, this concept comes up repeatedly so make sure you have it locked in.

Answer

The shared VSAM dataset may need to become a shared database table or encapsulated data service accessible to all 12 migrated modules

Answer

All 12 programs must be transformed into Java simultaneously to preserve data consistency

Answer

ADDI will automatically generate a DB2 CREATE TABLE statement equivalent to the VSAM record layout
