红帽全球峰会第 4 章 配置 Narayana 事务管理器
在 Fuse 中，全球交易经理是 JBoss Narayana 事务管理器，它是企业应用平台(EAP)7 使用的事务管理器。
在 OSGi 运行时，与用于 Karaf 的 Fuse 中一样，额外的集成层由 PAX TRANSX 项目提供。
以下主题讨论 Narayana 配置：
4.1. 关于 Narayana 安装
复制链接链接已复制到粘贴板!
Narayana 事务管理器在以下接口以及一些额外的支持接口中使用：
-
javax.transaction.TransactionManager -
javax.transaction.UserTransaction -
org.springframework.transaction.PlatformTransactionManager -
org.ops4j.pax.transx.tm.TransactionManager
7.11.1.fuse-7_11_1-00013-redhat-00003 分发使这些接口在启动时可用。
pax-transx-tm-narayana 功能包含一个嵌入 Narayana 的覆盖捆绑包：
karaf@root()> feature:info pax-transx-tm-narayana
Feature pax-transx-tm-narayana 0.3.0
Feature has no configuration
Feature has no configuration files
Feature depends on:
pax-transx-tm-api 0.0.0
Feature contains followed bundles:
mvn:org.jboss.fuse.modules/fuse-pax-transx-tm-narayana/7.0.0.fuse-000191-redhat-1 (overriden from mvn:org.ops4j.pax.transx/pax-transx-tm-narayana/0.3.0)
Feature has no conditionals.
fuse-pax-transx-tm-narayana 捆绑包提供的服务有：
karaf@root()> bundle:services fuse-pax-transx-tm-narayana
Red Hat Fuse :: Fuse Modules :: Transaction (21) provides:
----------------------------------------------------------
[org.osgi.service.cm.ManagedService]
[javax.transaction.TransactionManager]
[javax.transaction.TransactionSynchronizationRegistry]
[javax.transaction.UserTransaction]
[org.jboss.narayana.osgi.jta.ObjStoreBrowserService]
[org.ops4j.pax.transx.tm.TransactionManager]
[org.springframework.transaction.PlatformTransactionManager]
由于此捆绑包注册了 org.osgi.service.ManagedService，所以它会跟踪并对 CM 配置中的更改做出反应：
karaf@root()> bundle:services -p fuse-pax-transx-tm-narayana
Red Hat Fuse :: Fuse Modules :: Transaction (21) provides:
----------------------------------------------------------
objectClass = [org.osgi.service.cm.ManagedService]
service.bundleid = 21
service.id = 232
service.pid = org.ops4j.pax.transx.tm.narayana
service.scope = singleton
...
默认的 org.ops4j.pax.transx.tm.narayana PID 为：
karaf@root()> config:list '(service.pid=org.ops4j.pax.transx.tm.narayana)'
----------------------------------------------------------------
Pid: org.ops4j.pax.transx.tm.narayana
