Q

2PC

A

Two-phase commit - Commit and roll back - first check goes to all Resource Managers and checks whether everything is ok to commit, then decides whether to commit or not (2 phases) (if even one Resource Manager cannot go ahead, then the whole thing does not go ahead)- the idea that a transaction can be of multiple parts and that the system needs to either commit everything or roll back on everything if there is a failure

Q

ACID

A

Requirements of a transaction system: Atomicity, Consistency, Isolation, Durability Atomic: Meaning either all changes are made at once or not at all Consistency: Database remains consistent according to the rules defines such as referential integrity both before and after the transaction is executed Isolation: Requires that transactions are executed as if not other transactions are executed (e.g. hidden) Durability: When a transaction is stated as complete, the updates to the database are preserved irrespective of any system failures

A

Key Sequence Data Set: This is the most common use for VSAM. Each record has one or more key fields and a record can be retrieved (or inserted) by key value. This provides random access to data. Records are of variable length. So that the system can retrieve an item without searching all preceding items in the data set. Ideal for data items that are used frequently and in an unpredictable order.

170
