Status: Closed |
INSTANCE TRAP AFTER LOAD OPERATION FAILS AT VERY EARLY STAGE (USUALLY DUE TO OUT OF SYSTEM RESOURCES) |
| product: |
DB2 FOR LUW / DB2FORLUW / 910 - DB2 |
| Problem description: |
You may encounter an instance trap after a LOAD operation fails
(usually due to out of system resources) at a specific place
very early on (at LOAD startup stage).
The db2diag.log may show the following message indicating out of
memory condition, or other message indicating out of system
resources:

"No memory available in 'Database Heap'"
DIA8302C No memory available in the database heap.
The stack of failing LOAD buffer manipulator (db2lbm) looks
like:
ossDumpStackTrace
OSSTrapFile::dump
sqlo_trce
sqloEDUCodeTrapHandler
__invoke_dynamic_linker__
sqluTermLoadEDU
sqluInitLoadEDU
sqlulbuf
sqloCreateEDU
sqloSpawnEDU
sqlulInitOneEDU
sqlulInitNBM
sqlulCreateQAndEDU
sqluvload
call_sqluvload
It may be another LOAD process than db2lbm that fails; the
common signature is sqluInitLoadEDU() calls sqluTermLoadEDU()
and we trap inside sqluTermLoadEDU().
DB2 fails (due to out of system resource) early in LOAD
initialization code before setting up some internal pointers.
During LOAD termination DB2 frees resources and dereferences the
not initialzed pointer and traps. |
