南报业传媒物流集团RAC调整

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.

要求进入到机房之前以上全部弄好

标签出厂时贴好(电源、网线等线缆、机器、端口)

线缆布线符合要求, 线缆规划为同一个机柜为3M, 跨机柜为6M+

每台机器出厂前都需要由VIVO对系统进行远程验证，通过之后方能出厂

设备不经过机房仓库，直接搬入机房立即拆箱上架

理线架由我们提供并安装

每三个机柜一个交换机

线缆和服务器可以先上架

设备不能直接存入机房

纸箱由我们自行回收

标签需要提前确认好,包括规格、大小、字体（由VIVO提供）

2U机器每个机柜12台, 4个机柜一组

1U机器每个机柜18台, 4个机柜一组
