infinispan cluster of a predefined set of IP Addresses

问题 I am using infinispan to distribute the cache over multiple nodes using multicast which is working fine. Unfortunately, according to the System Admin requirements they don't want to allow multicast and they gave me a set of the possible node IP addresses. Is there a way programatically or via infinispan.xml or jgroups.xml to define the set of IP Addresses of the nodes instead of auto discovery? If not is there an alternative cache that fit the same requirement? 回答1: You need to adjust JGroups

JGROUPS Transport remoting start error using Infinispan

问题 In my use case I developed N webapplications, each of which uses Infinispan shared cache and JGroups as transport layer. When a webapplication starts up, it creates a cachemanager object and registers it into the JNDI of the application server. The next started webcapplication check the JNDI and if it finds a cachemanager already binded by another webapplication it uses it with a simple lookup calls. This way the first webapplication instantiating the distributed cache manager should be the

问题 So We have a problem where a penetration checker being run for something like 12 hours is causing Jgroups to disconnect, the slave doesn't rejoin the cluster, split brain, some other issues that represent the lack of replication, and it doesn't recover. <config xmlns="urn:org:jgroups" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:org:jgroups http://www.jgroups.org/schema/JGroups-3.6.xsd"> <TCP bind_addr="NON_LOOPBACK" bind_port="${infinispan.jgroups.bindPort}"

问题 So, I just setup two jboss nodes behind apache, enabled clustering and setup ehcache synchronization. Now with both nodes running, I get the following exception on the node that did not receive the request: ...

Custom hashing function in infinispan

蓝咒 提交于 2019-12-11 05:25:49
问题 I am using Infinispan version 8.2 .I already knew when an Node puts an entry to an Cache.It uses its internal hashing on the key and chooses a primary node in an cluster. I know that we can override this hashing with our custom hash function.But I don't know where to start and how to start.I have searched through a lot of documents and websites.But,none of them had a proper description in it. I want someone to help me in this. Thanks in advance. 回答1: If you speak about determining the

JGroups Instances communication

前提是你 提交于 2019-12-10 16:49:54
问题 I have two machines in which the JGroups is running. The Problem I am facing is, once a Instances is created in one of the machines, few seconds later I start the other Instances. Both of them initiate separatly(Same Cluster) i.e they don not join the cluster together. After 10 to 15 seconds they both communicate and join together. This delay is causing problem with my Business in the code... There is also a Warning thrown while startin the Program WARNING: send buffer of socket java.net

“experimental” status of JGroups Master/Slave backend for hibernate search and infinispan

对着背影说爱祢 提交于 2019-12-09 23:16:06
问题 We use hibernate-search for fulltext indexing of our entities in wildfly 8.2 (using the hibernate/hibernate-search and infinspan libraries inlcuded with wildfly 8.2). Running as standalone node or in a domain with a dedicated hibernate search master and the org.hibernate.search.store.impl.FSDirectoryProvider this has been working fine for several years (and jboss versions). We would now like to deploy this system to a HA clustered environment with wildfly 8.2 running behind a load balancing

JBoss 4.2.2 nodes start to cluster then suspect each other

问题 I have a website running with JBoss 4.2.2 on an existing Red Hat server. I'm setting up a second server so as to have a clustered pair (which will then be load-balanced). However, I can't get them to cluster successfully. The existing server starts up JBoss with: run.sh -c default -b 0.0.0.0 (I know the 'default' configuration doesn't support clustering out of the box - I'm using a modified version of it which includes clustering support.) When I start the second JBoss instance with the same
