PERFORMANCE ISSUE OF CLOSE FOR UR/CS CURSORS WHEN 'WITH RELEASE' IS SPECIFIED |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
If "WITH RELEASE" is specified on a CLOSE of a cursor opened
with isolation UR or CS (or equivalently if
SQL_ATTR_CLOSE_BEHAVIOR is set to SQL_CC_RELEASE for a UR or CS
isolation cursor), the close cursor processing may be delayed if
the transaction holds many locks.
With the change introduced in this APAR, the performance of such
a close (with RELEASE) will improve and will not be sensitive to
the number of locks held by the transaction. |
