FACT(s) (Environment):

SCO OpenServer 5.0.5

FACT(s) (Environment):

Progress 9.0B

SYMPTOM(s):

Database appears to hang.

promon shows millions of records being accessed and millions of record locks.

CAUSE:

The database only seemed to be hanging. A "find last .. exclusive" statement without an index was being used, so the records were being read sequentially (and slowly). Users were misinterpreting this behaviour as a hang.

FIX:

Ensure that an appropriate index is used.
