Informix - Problem description

Problem IT31725 Status: Closed

"CANNOT UPDATE PAGEZERO" ERRORS WHILE UPGRADING FROM PRE-12.10.XC8 TO
14.10 LEAVING PAGEZERO IN A DUBIOUS STATE

product:
INFORMIX SERVER / 5725A3900 / E10 - 
Problem description:
Upgrading an instance from a version before 12.10.xC8 to 14.10
will modify pagezero's initial slot (#1) to its new, larger
shape, but store it on the page still with old slot length (252
rather than 276).

One consequence might be a corrupted second slot (#3) and, as a
consequence, "Cannot update pagezero" errors, typically seen on
secondary servers.

To see the problem run the following in version 14.10:

oncheck -pP 1 0 | head -5

addr             stamp    chksum nslots flag type         frptr
frcnt next     prev
