When using Load utility to add data into a range partitioned
table, a BAD PAGE error can be reported by one of the db2lbm
processes.
db2diag.log will include an entry similar to this::

MESSAGE : ZRC=0x86020001=-2046689279=SQLB_BADP "page is bad"
DIA8400C A bad page was encountered.
Stack trace generated by error may contain entries like this:
sqlb_verify_page
[...]
sqluDirectRead
sqluTransformSendToCopyRequest
sqluSetCBitsAndWriteBuf
sqlulBMCont
sqlulbuf
sqloEDUEntry
The problem may be more suseptible when the COPY YES option is
used.
Per usual Load recovery usage, execute a Load Terminate to bring
the table back to consistent state, then you can try the Load
again. | |
