Problem IC63765
|
Status: Geschlossen |
DUPLICATE CLOSING SOCKET DURING TERMINATING TCPIP CONNECTION MANAGER(DB2TCPCM). |
| Produkt: |
DB2 FOR LUW / DB2FORLUW / 950 - DB2 |
| Problembeschreibung: |
If db2 instance has more than one db2tcpcm processes, when they
are requested to be terminated while instance stopping, they
will close same socket simultaneously. As a result, only one
db2tcpcm can close socket without error, while other db2tcpcm
processes will received an error from system call. Then, those
failed db2tcpcm processes will report a DIA3208E error in
db2diag.log as follow.

| Local-Fix: |
set db2 register variable DB2TCPCONNMGRS to 1, then recycle the
instance. But, please note that DB2TCPCONNMGRS=1 will degrade
connecting performance. Please refer to corresponding topics
about "DB2TCPCONNMGRS" in db2 information center. |
