Problem IC79597
|
Status: Closed |
DATABASE ACTIVATION IS SLOW WHEN THERE ARE MANY DMS CONTAINERS DEFINED ON LARGE DPF SYSTEMS. |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
During the database activation there is an unnecessary call to
open/lock/close DBM CFG cfg file for every DMS container, so
systems having high number of tablespace/containers are
impacted.
The time required to access DBM CFG directly from the file can
be significant, especially on MPP systems where the DBM CFG is
NFS mounted. This problem results in longer time necessary to
complete database activation process. |
