Subject: Test Fix for LE/370 Programs running with IBM apar PK28112







Hi,



=20



I see that there is a test fix for LE/370 programs when IBM apar PK28112

has been applied. Did someone on the list get this raised or is this

part of running IDMS under z/OS 1.9 pre-release testing by CA? We are

about to go z/OS 1.8 and I like to be prepared for problems. It raises a

T03C abend.

Thanks

Unsorted indexes
"Can someone please tell me- How do you define a system-owned index that
is unsorted? And also, why would you want to? Is there some advantage
in an unsorted index as compared to a sorted one? Thanks in advance.

Re: Unsorted indexes
"One ""why"" would be to ""area sweep"" an area for a record that sparsely
populates the area. By using an index you only hit pages that contain the
record.

Consider a database of 5,000 pages that contains a ""STATE"" record stored
calc. (e.g., California, Nevada). If you didn't hang it off an OOAK or a
system index, it would take you 5000 I/Os to see all of them, instead of 50
(plus a few for SR7/SR8s).
