Tuning the RAC for Satellite Connectivity
The RACADM.EXE utility may be used to modify the network tuning properties of the RAC. It is also
possible to use the racadm.cfg file to modify these properties (similar to the manner in which .ini files
are used).
racadm config -g cfgNetTuning -o cfgNetTuningNicMtu <
value >
racadm config -g cfgNetTuning -o cfgNetTuningIpTtl <
value >
racadm config -g cfgNetTuning -o cfgNetTuningIpReassTtl <

racadm config -g cfgNetTuning -o cfgNetTuningTcpReXmtMin <
value >
racadm config -g cfgNetTuning -o cfgNetTuningTcpReXmtMax <
value >
racadm config -g cfgNetTuning -o cfgNetTuningTcpMsl <

where <
value > is obtained from Table A-1.
