Enable Private Network Jumb frame support

step 1

• on H3C S5XXX

system-view
interface range Gigabitethernet1/0/5 to Gigabitethernet1/0/6
jumboframe enable
interface range Gigabitethernet2/0/5 to Gigabitethernet2/0/6
jumboframe enable

display interface GigabitEthernet1/0/5

step 2

• on RAC nodes, edit ifcfg-bond1

cat >> ifcfg-bond1 <<"EOF"
MTU = 9000
EOF

• then restart bond1

ifdown bond1 && ifup bond1

disable NTP

Stop NTP and CRS

• on RAC nodes Linux (root)

# chkconfig ntpd off
service ntpd stop
mv /etc/ntp.conf /etc/ntp.conf.original

• optional

crsctl stop crs
crsctl start crs

verify clock is in sync on one of the node (grid)

# crsctl check ctss
CRS-4701: The Cluster Time Synchronization Service is in Active mode.
CRS-4702: Offset (in msec): 0

# cluvfy comp clocksync

Verifying Clock Synchronization across the cluster nodes

Checking if Clusterware is installed on all nodes...
Check of Clusterware install passed

Checking if CTSS Resource is running on all nodes...
CTSS resource check passed


Querying CTSS for time offset on all nodes...
Query of CTSS for time offset passed

Check CTSS state started...
CTSS is in Active state. Proceeding with check of clock time offsets on all nodes...
Check of clock time offsets passed


Oracle Cluster Time Synchronization Services check passed

sqlnet.ora

sqlnet.expire_time

sqlnet.expire_time = 10

So do you need to restart anything to start using the sqnlet.expire_time parameter? No you do not for new sessions! If you want to use the new value for existing sessions you have to make these sessions reconnect.
