zUID is a cloud enabled service in the z/OS environment that generates a unique identifier using a specialized patent-pending algorithm. It is guaranteed to generate 100% unique identifiers until the year 34,000 without requiring a database system to manage.
Service returns the UID in 3 different hex formats, plain, guid and ess in plain text format. They are not wrapped in XML or JSON structures.
- plain: 32 bytes, 1234567890abcdef1234567890abcdef
- ess: 34 bytes, 12345678-90abcdef12345678-90abcdef
- guid: 36 bytes, 12345678-90ab-cdef-1234-567890abcdef
No authorization is needed for this service.
In addition to being web enabled you can call this routine directly using a CICS LINK command in your COBOL programs. The HTTP interface was designed to make it available for more consumers outside the z/OS environment.
