[TRAFODION-3003]Trafodion keepalive support
Keepalive could be configured by modifying file
src/main/java/org/trafodion/dcs/Constants.java or
src/main/resources/dcs-default.xml
Modify variable DCS_SERVER_PROGRAM_KEEPALIVE_OPT;
It's a string with parameter ENABLE IDLETIME INTERTIME RETRYCNT (Seconds)
ENABLE=enable/unenable/default ,IDLETIME= number
,INTERTIME=number,RETRYCNT=number
e.g:
ENABLE=enable,IDLETIME=300,INTERTIME=5,RETRYCNT=3
Default value is 1,3600,3,20(Only effective when value configured is set
incorrectly)
The value will be read in when mxosrvr start. Mxosrvr will set the socket
after getting a connection.
