Status: Closed |
SLOW DB2START IN MICROSOFT CLUSTER (MSCS) ENVIRONMENT |
| product: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problem description: |
A db2start on Windows Cluster environment may be slow due to
issue in DB2 licensing module.
The delay can be seen between the following two messages in the
db2diag.log file:
