How to troubleshoot debug VIP problems:
-----View statistics for node application resources:
/u01/crs/bin/srvctl config nodeapps-n dbtest2-a-g-s-L
VIP exists.:/dbtest2-vip/10.11.11.198/255.255.255.0/eri0
GSD exists.
ONS Daemon exists.
Listener does not exist.
------Debug VIP
Further debug it by uncommenting the environment variable _usr_ora_debug=1 in the script $ORA _CRS_HOME/BIN/RACGVIP
OR simply as root user, issue the command:
Crsctl Debug Log res "Ora.dbtest2.vip:5"
Turn off debu
Shared guard version 2.0 has added many features. The most important one is that it can provide automatic host switch. In order to ensure the implementation of the host switching function, the configuration is much more complicated than Version 1.0, especially when users use the fixed IP Mode of a single Nic, the concept of the virtual network card and the virtual gateway is not very clear, resulting in configuration errors and cannot access the Inter
Recently, some friends have reported that they are not familiar with the configuration of wireless gateways, so I will explain in detail some questions about wireless gateways, including the selection of wireless gateways, wireless gateway settings and explanations of some related terms.
In a broad sense, a "Gateway" refers to the "interface" connecting a network to another network. For example, if an enter
Gateways (Gateway) are also known as inter-network connectors, protocol converters. The gateway realizes network interconnection above the network layer, is the most complex network interconnection device, only for two high-level protocol different network interconnection. Gateways can be used for both WAN interconnection and LAN interconnection. A gateway is a c

The Gateway technology in the network is also called the inter-network connector and Protocol converter. The gateway implements network interconnection on the transport layer. It is the most complex network interconnection device and is only used for different network interconnection between two high-level protocols. Gateways can be used for both wide-area Internet and Local Internet. A
Router and three-layer switch experiment Demo--a gateway that acts as a two VLAN--Hundred dishes background : We know that routers have routing capabilities, so you know how to configure two gateways on a router interface (such as a two VLAN gateway)? Note that it is on one interface instead of two, and we sometimes use the three-layer switch as a router, so how do we configure the three-tier switch at this
External Gateway Protocol: BGP (Border Gateway Protocol)
BGP: the protocol for exchanging route information between as routers of different self-made systems.
The Internal Gateway Protocol rip or OSPF is used to send a datagram to the target site from the source site as much as possible in an. However, the external gateway
The contact with the vswitch has been around for a while, and you may find that some content is getting confused. For example, if the vswitch configures the default gateway, the specific configuration commands are quite familiar, but now I don't quite understand why I want to complete the switch gateway settings. I also found some information on the Internet, some for remote access to the switch, and some f

Background
As we all know, Docker has made a profound change in the IT world these years,From development to testing to operations, there is a shadow of it everywhere.It also facilitates the micro-service architecture and moves forward.
In the latest version of Docker (CE 17.03), with swarm mode the maturity,In a simpler scenario, you can no longer need a special 基础设施管理服务编排, 服务发现 , 健康检查 , and 负载均衡 so on.
But API
Through the previous sharing, we learned about several core facilities of the microservices architecture, through which we can build a simple microservices architecture system. For example, through spring Cloud Eureka to build a highly available service registry and realize the registration and discovery of services;Load balance through the Spring cloud ribbon or feign, and fault-tolerant protection with spring cloud Hystrix to avoid a failure spread. After the microservices are set up, we will
Spring Cloud (11): Service Gateway Zuul (filter) "Version Finchley" Posted in 2018-04-23 | updated on 2018-05-07 | In the previous article we learned about the basic functionality of Spring Cloud Zuul as a gateway: Routing (Router). In this article, we will focus on another core feature of Spring Cloud Zuul: Filter.The role of FilterWe have been able to implement the routing capabilities of the request
I. Preface:
To build the strongswan environment and configure the net-net mode, two gateways are required.
In addition, the gateway has many functions. For example, you do not need a router to share the internet. The most classic is that if a computer has Bluetooth, it can connect to the Internet and share it via Bluetooth, so that other people can access the Internet wirelessly (I have heard of it and have no practice ).

page is usually more detailed than the mobile version.
Different types of clients have different network performance. For example, mobile networks are generally slower and higher latency than non-mobile networks. Of course, a wide area network (WAN) is much slower than a local area network (LAN). This means that the network used by the mobile local client differs greatly from the performance characteristics of the server-side Web application's LAN. A server-side web app can send a large num
As we all know, walking from one room to another must pass through a door. Similarly, sending information from one network to another must pass through a "gateway", which is the gateways. As the name implies, the gateway is the "gate" of a network connected to another network.According to different classification standards, there are many kinds of gateways. The gateway
