Problem IC76773
|
Status: Closed |
THE INSPECT TOOL CAN LEAK MEMORY WHEN INCORRECTLY INSERTING A COMPRESSION DICTIONARY |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
The DB2 INSPECT ROWCOMPESTIMATE option estimates the
effectiveness of row compression for a table. It can leak memory
when the compression dictionary was built successfully but
attempting to insert it into table didn't succeed or complete.
For such case, the dictionary should be free'ed from the memory.
The most common situation for this is when INSPECT
ROWCOMPESTIMATE runs against a table that does not support data
row compression. |
