Problem IC85740
|
Status: Closed |
LOAD INSERT INTO MDC TABLE WITH COMPRESS ENABLED BUT NO DICTIONARY EXISTS YET, AND IS INTERRUPTED, MIGHT TRAP/SEG-FAULT. |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
If a table is enabled for Compression, but no dictionary exists
yet, and the table contains existing data, and a Load INSERT is
invoked, then Load's Automatic-Dictionary-Creation logic may
attempt to sample existing data in the table. If the table is an
MDC table and this Load is interrupted, in some timing
situations this could cause a trap or seg-fault.
Symptoms include a trap file with the following stack:
<StackTrace>
...
sqloEDUCodeTrapHandler
sqlbfix
sqlbFixPage
sqluFixPage
sqluMDCFixBMP
sqlulAdcTableScanner
sqluCTableScanner
sqluLoadEDUDriver
OR similar stack but with sqlbufix instead of sqlbfix, for
example:
...
sqlbufix
sqluMDCUnfixBMP
sqlulAdcTableScanner
sqluCTableScanner
sqluLoadEDUDriver |
