DIA3208E Error encountered in TCP/IP protocol support

30 March,2013 by Jack Vamvas

Question : I recently received a query from an application owner, who reported application outage issue.

 An inspection of the db2diag.log file found this message. How can I solve this problem?

DIA3208E  Error encountered in TCP/IP protocol support. TCP/IP function "close". Socket was "3". Errno was "9".
 Errno was "9".

 

Answer: The DIA3208E  Error encountered in TCP/IP protocol support  message indicates multiple db2tcpcm processes. If the instance is stopping and there is an attempt to terminate the sockets simultaneously , only one can close without an error

Option 1 -   db2set DB2TCPCONNMGRS=1

Option 2 – Install DB2 version 9.5 FixPack 6
