12. Build High-availability Ovirt (hosted engine)
I wrote this article when Ovirt has been updated to 3.4.
In this case, we will use the previously created distributed-replicate storage, so that the high availability of the system services can be guaranteed to be increased.
Here are a few things to note:

database resourcesIn addition, in some multi-process, single-threaded environment (such as PHP), the use of connection pooling technology is basically impossible.The introduction of DRCP can solve these problems effectively, DRCP bind the session and server process together for caching (pool server), when the user requests to connect to the database, the first connection to the connection broker process, The broker process selects pool server from the connection pool based on connection informa
OVirt v3.4 began to support hosted Engine. What is hosted engine? Very simply, the previous management node was deployed on a physical machine, and now we deploy the management node to a virtual machine, and the virtual machine runs on the compute nodes in the Ovirt virtualized environment. Previously, the management node was deployed, the compute nodes were deployed, and the compute nodes were registered t

The previous article describes how to make an engine Appliance. How do you use it when appliance is made? The following is a detailed introduction to the use of engine appliance.First, we need a physical server on which to install the CentOS7.0 operating system first.

Starting today, the ASP. NET Web API (hereafter, sometimes referred to as the Web API) is studied. I will write a practical series of topics, not necessarily into a theoretical system, just encounter problems or experience, write down. Gain a deeper understanding of the ASP. NET Web API for a longer period of time. Here I use the VS2013 integrated development environment, if the version is not enough, you can use NuGet to download the Web API-related DLL.Discuss the self-
The TCP-bound WCF Service is hosted in IIS.

After receiving the previous blog post, we continue to parse network data packets and parse the three protocols that are hosted on the Ethernet. This mainly involves first parsing the header data according to the RFC-defined standards and then obtaining the payload, that is, the entity data contained in the Protocol is further processed by the upper layer.I.

In Springboot, it is sometimes necessary to call your own function, but you cannot use a DAO or service that is hosted on spring.Most of the information on the Internet is said to add some comments or something, try to not succeed.Finally, a possible solution was found in a blog post:Original address: http://blog.csdn.net/xiaoyu411502/article/details/51392281First create the tool class as follows:Importorg.springframework.beans.BeansException;ImportOr
And then
Resource resource=new Classpathresource ("/web-inf/applicationcontext.xml");
Beanfactory factory=new xmlbeanfactory (Resource);
Sessionfactory sessionfactory = (sessionfactory) factory.getbean ("Sessionfactory");
You can get it.
The rest will not be melted down, my practice is to modify the Hibernateutil file to get the Sessionfactory method to solve everything
