jboss cep

CEP is the complex event processing abbreviation, which translates to complex event processing (composite events may be more accurate).1. Why do we need CEP? CEP is a function of real-time analysis and quick response. Let's consider the significance of CEP in one case. Classic case: Real-time statistics of the past red

2. Drools support two semantic event, point in time and interval (difference is whether the @duration annotation is 0)3. Notes:1. @role default fact, CEP time @role (event) identifies fact as an event2. @timestamp, each event has a related timestamp, which is obtained from the system by default (that is, the time to insert the session), or it can be assigned externally3. @duration, the duration of each event is 0 in Point-in-time event, and the

I. Events (EVENT) is defined by the schema. is the tuple of the event property Flow (stream) event flow Time ordered sequence of event is a chronological sequence of events Append-only cannot remove events, only append unbounded Without Borders. STREAM examples: {1s, event1}, {2s, event2}, {4s, event3}} Valid stream {1s, event1}, {4s, Event2}, {2s, event3}} not a STREAM, this is a EVENT CLOUD. Third, relationship relation Some instantaneous package event Allow inserts, dele

Recent exposure to application server JBoss, in addition to the JBoss Web and Tomcat as a Web server, then consult the data to compare the three, for your reference.First, TomcatThe Tomcat server is a free open source Web application server. Support for the latest servlet and JSP specifications. Because of the advanced Tomcat technology, stable performance, and free, so deeply loved by Java enthusiasts and

What is an enterprise application cluster Cluster refers to the aggregation of different servers together, a collection of servers, which provides the client with a virtual platform, so that clients do not know the structure of the server collection can be deployed to the server collection of applications, access to services and other operations. Clustering is a key feature of enterprise applications, and it can provide: High scalability: You can add as many servers as you want to the cluster

JBoss can start Minimal,default and all in 3 ways by default. The number of modules in the three modes is incremented sequentially For example: 1-Execute Jboss_home/bin/run.bat batch file to start JBoss, start with default of 2-run run-c All in the command, JBoss will start with the all Model 3-You can customize a server to suit your needs, such as building a te

JBoss as JBoss EAP and Wildfly JBoss, an Open-source application server based on Java EE, follows the LGPL license, meaning it can be used free of charge in any business application. 2006, JBoss was acquired by Redhat company.JBoss as the upstream foundation of the Redhat Company's commercial product

Using the Apache httpd (mod_cluster) and JBoss architecture for highly available cluster environments, use Apache httpd (MOD_JK) and JBoss architectures for highly available cluster environments and use Apache httpd (mod_proxy) As described in the highly available cluster environment of the JBoss architecture, we typically build cluster applications by using the

Use JBoss + Oracle to use oracle-xa-ds.xml for Distributed Transaction Processing We will configure two or more databases and report the following when starting JBoss: Org. JBoss. Deployment. deploymentexception: trying to install an already registered mbean: JBoss. JCA: service = oraclexaexceptionformatter

Problems encountered and to be solved in the company project1: In principle, in addition to their own code, the public jar should not be packaged in the ear, so the package is too large, also does not conform to the layered logic, inside the JBoss container, each ear of the packet repeat jar will be transferred to the internal JBoss, resulting in a waste of excessive server resources, An occasional exceptio

Original:[Java] [JBoss] Change JBoss Deployment directory (virtual directory)In the development process, sometimes we want to put the program in our source code directory, such as D:\code, rather than on JBoss deploy, what to do?We know that we have Tomcat integrated in JBoss, so you can configure this directory just l

Because JBoss uses Log4j,jboss, the system log level by default is info. Hibernate or Ibatis to print SQL, level debug, so the program set the log4j level for debug will be installed by the JBoss system info to be overwritten.To resolve this issue, you need to manually configure the log4j logging level for JBoss:1. Ope

Window Most of the cases, we are running JBoss continuously, how to ensure that it is not subject to external interference and continue to run will not be closed? Under the Unix/linux, the shell should be complete then under Windows? In order to achieve this, JBoss must be installed as a system service, and JBoss itself or Windows itself does not provide a way to

. Install jbossExtract jboss to a directory such as/usr/local/jboss, add "/usr/local/jboss" to the path, and set jboss_home = "/usr/local/jboss"Run. sh and open the browser http: // localhost: 8080. If the test page is displayed, the installation is successful! Configure. bash_profile in the/root directory to add Envir

First of all, the topic is a pseudo-proposition, the JBoss container is not supported directly deploy executable jar package, jar will only be loaded as Lib treats. A small workaround is provided here.Today, I have a problem, the monitoring module in our project to separate into a small project deployment, monitoring logic is relatively simple, the implementation of this small project only rely on some common jar and spring JdbcTemplate.So I always do

First, JBoss's JSF implementation differs from the Sun's implementation, which leads to the following error when we use MyEclipse to deploy JSF. Com.sun.faces.config.ConfigurationException:CONFIGURATION failed! The solution is: 1. Overwrite $jboss_home/server/$YOUR _config/deploy/jbossweb.sar/jsf-libs/package with the implementation of the Sun JSF 2. When the project refers to the package, it directly references the $jboss_home/server/$YOUR _config/deploy/jbossweb.sar/jsf-libs/these packets with

Symptom: During JBoss startup and deployment, due to software package problems, the deployment time exceeds the default JBoss time (60 seconds). JBoss redeployment interrupts the previous deployment. This repetition causes the website to fail to start. Code: KB-E1037 Issue: There is an error message in log file while deploying
