POTENTIAL PAGE ZERO CORRUPTION BY ONMODE -C BLOCK | |
Produkt: | |
INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 | |
Problembeschreibung: | |
It has been observed that after an 'onmode -c block' the free counter of root chunk's page zero is zero. So the page header no longer is intact and any future flushing of this page to disk, e.g. for an increased "Maximum server connections" value, would cause the root chunk and the server to go down. You can determine this corruption in an 'oncheck -pP 1 0' output whose 'frcnt' value is zero. This can go unnoticed for a long while on a primary or standard server, but a level 0 restore or a backup of such corrupted system, e.g. for setting up a secondary server, would cause assertions soon after it finished. | |
