Hi identicle.
HURBA is an acronym for:
High
Use
Relative
Byte
Address
You'll see it used to denote the relative position of the last record in an ESDS or RRDS Vsam file. There may be other non-VSAM files that use the teqnuque, but I haven't seen much of them in recent years.
P.S. It's bad form to pose a new unrelated ques in the same thread as the original. Just ckick the "NEW TOPIC" button near the top of the page to start a new thread. |

Hi,
If you analyze the output of the LISTCAT command there is ALLOCATION information which shows two fields HURBA and HARBA.
HIGH-USED-RBA indicates the Relative Byte Address(plus 1) of the last used data control area. This value reflects the portion of the space allocation that is actually filled with data records.
There are actually two HURBAs one in the VSAM control block of the cluster and one in the catalog entry for the cluster.
Hope this helps, |
