Status: Geschlossen |
DATABASE CONNECT AND SNAPSHOT TIMES DEGRADE DUE TO TIMESTAMP GENERATION WHEN DATABASE IS SERIALIZED |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
On some platforms, the generation of a timestamp can be a
relatively expensive operation to perform. Some timestamps are
generated while the database is serialized when new connections
are arriving or when a database snapshot is being performed. The
timestamp generation can cause these serialization periods to
last longer and lead to contention that can cause database
applications to be delayed. |
