| Produkt: |
DB2 FOR LUW / DB2FORLUW / A10 - DB2 |
| Problembeschreibung: |
In Version 9.7 Fix Pack 5, chances of having a memory leak have
been introduced. To check if a memory leak has happened, issue
the db2pd -memb command and check if the output of the command
looks similar to the following output:
Memory blocks sorted by size for private pool:
PoolID PoolName TotalSize(Bytes) TotalCount LOC File
88 private 264376936 164622
1541 2904145706

The private memory usage in file 2904145706 at line 1541 keeps
leaking and consumes physical memory.
This memory leak can happen if a query uses a LOB locator for
the output column.
Example:
ODBC application does:
select substr( clob_column, 1, 30 ) from t1
SQLBindCol is done with with SQL_C_CLOB_LOCATOR
The query is returning a LOB column, but the client wants a LOB
locator. |
