product: | |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 | |
Problem description: | |
The customer has a busy system where all users are running with a shared memory connection. There is a need to run update statistics medium / high on some columns which are not part of any associated indexes. Reviewing procstack for the running thread shows we are constantly within usbldist->uscoldist during the delay / hang. The hung sessions are able to run again after the update statistics completes. | |
