Problem IC73419
|
Status: Geschlossen |
SLIGHT OVERLAP DURING DATABASE DEACTIVATION/REACTIVATION THAT MAY LEAD TO OLD/NEW DATABASE MEMORY ALLOCATED AT THE SAME TIME. |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problembeschreibung: |
The current design of deactivation/activation of a database
partition allows there to be a slight overlap where, at the
point where shared memory is allocated for the "new" activation,
shared memory from the previous activation has not yet been
freed. Note that all activity is completed for the old
activation, it is just the shared memory itself that may not yet
be freed.
This may lead to diag.log messages such as the following which
indicate that we are exhausting shared memory resources:
