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.

VIVO会议

以下工作分工确定?

1. RAID prepared
2. Disk Partition by UUID, Filesystem type
3. 服务器标签出厂时贴好
4. 要求进入到机房之前以上全部弄好

安装规划和要求

1. 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+
2. 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
3. 设备不经过机房仓库，直接搬入机房即拆箱上架
4. 理线架由我们提供并安装
5. 每三--四个机柜一个交换机
6. 线缆和服务器可以先上架
7. 设备不能直接存入机房
8. 纸箱由我们自行回收
9. 2U机器每个机柜12台, 4个机柜一组
10. 1U机器每个机柜16台, 4个机柜一组
11. 服务器是直接放入机柜托盘
12. 服务器标签拉条定制（增加IP地址和序列号）
13. 确认服务器中千兆和万兆卡的位置
14. 标签需要提前确认好,包括规格、大小、字体（由VIVO提供:电源、网线等线缆、机器、端口规划表)

人员需求

1. 要求7x24服务。机房提供7x24x365服务。
2. 需要多少人员，分工问题(标签打印、线缆贴标签、服务器拆箱、上架、布线)
