Problem IT37863
|
Status: Closed |
HADR GRACEFUL TAKEOVER CAN TIMEOUT DUE TO SUSPENDED DB2AGENT PROCESSES
|
| product: |
DB2 FOR LUW / DB2FORLUW / B50 - DB2 |
| Problem description: |
When agents were trapped, they may be suspended. These suspended
agents would prevent the completion of graceful takeover. User
applications are not forced off during graceful takeover.
One way to identify the suspended agents is checking the stack
files during takeover.
$ grep db2agent *stack.txt | grep HADRDB | uniq
26217.2371.000.stack.txt:EDU name : db2agent (HADRDB) 0 [-]
...
26217.7975.000.stack.txt:EDU name : db2agent (HADRDB) 0
(suspended) 0 [-]
26217.7991.000.stack.txt:EDU name : db2agent (HADRDB) 0
(suspended) 0 [-]
We can also identify the suspended agents from the output of
"db2pd -edus" |
