Is there a application program coding difference between local and central version mode in IDMS?

Correct Answer: An OOK-Rec is a one of a kind record set, used to get to another record set

Correct Answer: They communicate via service MVS request calls

Correct Answer: Autostatus is a protocol mode which causes the expansion of each DML statement to include a 'perform IDMS-Status' statement

Correct Answer: Following guidelines to be following while writing Cobol program: - Use ? EVALUATE ? statement for constructing cases - Use scope terminators for nesting - Use in-line Perform statement for writing ?do? constructions - Use Test Before and Test After in the Perform statement while writing Do-While statements

Correct Answer: There are some differences: COBOL II supports structured programming by using in line Performs and explicit scope terminators It introduces new features (EVALUATE, SET TO TRUE, CALL BY CONTEXT, etc) It permits programs to be loaded and addressed above the 16-megabyte line It does not support many old features (READY TRACE, REPORT-WRITER, ISAM, etc) It offers enhanced CICS support

Correct Answer: It generates a bind run-unit and binds all the records for the sub-schema the program is referencing

Correct Answer: No difference There is a difference between obtain first and obtain next for an area sweep, but not when current on the owner in a set

Correct Answer: IDMS uses record locks to prevent another run-unit from updating the same record

Correct Answer: A junction record is a member record type that allows for many-to-many relationship between its two owner records

Correct Answer: Currency is the location within the database during run-unit execution There are four levels of currency: - Current of run-unit is the record occurrence of the last successful find or obtain; - Current of record type is for the most recent of each record type; - Current of record set is the most recent within each set - Current of area is within each area
