A guaranteed UUID contains a reference to the network address of the host that generated the UUID, a timestamp (a record of the precise time of a transaction), and a randomly generated component. The UUID relies upon a combination of components to ensure uniqueness. Depending on the specific mechanisms used, a UUID is either guaranteed to be different or is, at least, extremely likely to be different from any other UUID generated until 3400 A.D. In addition, the UUID can be generated within the application server layer rather than the database, negating the need for extra round-trips to query the value of sequences or automatically assigned primary key values.Ī UUID is a 128-bit number used to uniquely identify an object or entity on the Internet. The use of a Universal Unique Identifier (UUID) solves this problem as each number is unique, rather than the next value in a sequential list of numbers. The use of sequences can cause a problem during data migrations and replication processes where duplication of the sequences occur. Oracle sequences are frequently used to provide unique numbers for primary keys where an appropriate unique key is not available. Universal Unique Identifier (UUID) - In Oracle We are looking for this function in DB2 Zos and LUW. Oracle (sorry to compare!) has ability to generate a UID.
