DB2 - Problembeschreibung

Problem IC71037 Status: Geschlossen

SYSPROC.DB2LOAD MAY TRAP WHEN INVOKED SIMULTANEOUSLY BY TWO OR MORE
APPLICATIONS.

Produkt:
DB2 FOR LUW / DB2FORLUW / 970 - DB2
Problembeschreibung:
The SYSPROC.DB2LOAD stored procedure may trap if it is invoked 
simultaneously by two or more applications. The procedure was 
not thread-safe in the new v95 threaded engine architecture. 
The stack of the trap files would usually show a clp routine at 
the top of the stack, like so: 
 
<StackTrace> 
sqloCrashOnCriticalMemoryValidationFailure 
sqlofmblkEx 
clpprs 
clp_parse 
clpParseLoad 
sqluParseAndExecuteLoad 
db2load 
sqloInvokeFnArgs 
 
or 
 
<Stack Trace> 
sqloCrashOnCriticalMemoryValidationFailure 
sqlofmblkEx 
clpPostLoadFreeDynMem 
sqluParseAndExecuteLoad 
db2load 
sqloInvokeFnArgs 
 
This APAR fixes the this thread-safety issue.
