GRACEFUL TAKEOVER COULD HANG FOR DB2 HADR DATABASE |
| product: |
DB2 FOR LUW / DB2FORLUW / 970 - DB2 |
| Problem description: |
Takeover command on DB2 HADR standby could hang because HADR
fails to force off all applications on primary.
When this happens, from db2pd -db <dbname> -hadr, you can see
value of ClientsRemainingOnP is not 0. And from db2pd -edus, you
can see some "db2agent" EDUs remaining. |
| Problem Summary: |

* PROBLEM DESCRIPTION: *

| Local Fix: |
The workaround to prevent this issue is to stop all applications
on the primary before issuing a takeover.
If the issue has been encountered, then you need to restart the
primary HDAR server. |
