Problem IC62752 | Status: Geschlossen |
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. | |
