Problem IC71037
|
Status: Closed |
SYSPROC.DB2LOAD MAY TRAP WHEN INVOKED SIMULTANEOUSLY BY TWO OR MORE APPLICATIONS. |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
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. |
