However, after the adjustment, the fault still persists.
04:17:37. 822: [CRSRES] [11025] 32ora. hostname1.vip on hostname1 went OFFLINE unexpectedly
To identify the cause, collect the information of ora. hostname1.vip. log and racgvip again for analysis.
The analysis results are as follows:
The following code is available in the racgvip program:
# Check the status of the interface thro 'pinging gateway
If [-n "$ DEFAULTGW"]
Then

the data to be monitored, use Topbeat as the resource usage measurement standard, use Filebeat as the real-time Log File Analysis, and use Packetbeat to analyze online network data.
There are many optional tools, such as what you know, what you like, or what you want to learn. The most important thing you need to remember is to make sure that you know your benchmark data before you start the modification operation.

binding also runs in this mode, and modifies the MAC address in the driver, changing the MAC address of the two NICs to the same, can receive data frames of a specific Mac. Then, the data frame is sent to the bond driver for processing. Then we check the RC. in the local file, due to the carelessness of the system engineer, the NIC binding configuration is incorrect, so a slight configuration error will cause an IP address to correspond to two different MAC addresses, it will obviously cause ne

SPAN traffic -- span trafficUse a local span to monitor all network traffic, including multicast, Bridge Protocol Data Unit (BPDU), and CDP,VTP, DTP, STP, pagp, lacp packets. rspan cannot monitor layer-2 protocols.

The purpose of configuring a virtual IP address is to achieve high availability. After that, let's take a look at how to set a virtual IP address in ubuntu12.04.
First, let's take a look at my Ubuntu IP:
chenshu@sloop2:~$ ifconfigeth0 Link encap:Ethernet HWaddr d0:67:e5:ef:5a:6e inet addr:10.112.18.158 Bcast:10.112.18.255 Mask:255.255.255.0 inet6 addr: fe80::d267:e5ff:feef:5a6e/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
then traced back. To achieve quick summation, we can create an additional array a [d] [I] when creating a tree, indicates the sum of the I elements and the previous elements on a node at Layer D.

first virtual machine. We will use this machine as the DHCP server.
4.1 modify the network configuration. Because "VirtualBox Host-Only Ethernet Adapter #2" does not enable DHCP, We need to specify a static IP for eth2. Here we use the following configuration
Address: 192.168.145.101Netmask: 255.255.255.0Gateway: 192.168.145.1
...eth1 Link encap:Ethernet HWaddr 08:00:27:1F:20:36 inet addr:10.0.2.15 Bcast:10.0.2.255 Mask:255.255.255.0 inet6 addr: fe80::a00:27ff:fe1

3. Create two VMS for CentOS6 and specify two NICs respectively.The first ENI uses the NAT mode to connect to the Internet.The second Nic uses the Host-Only mode. Remember to select the new "VirtualBox Host-Only Ethernet Adapter #2" in the previous step ″.
4. Start the first virtual machine. We will use this machine as the DHCP server.
