glassfish 4.1 和 JMS 集群

Question

我已经创建了集群“mycluster”、两个本地实例以及资源 jms/Queue1、jms/Queue2 和 jms/Topic 以及目标服务器和集群。

所以我就这样创建了集群：

- create-cluster mycluster

- create-instance --node localhost-domain1 --cluster mycluster instance01

- create-instance --node localhost-domain1 --cluster mycluster instance02

[...]

- start-cluster mycluster

- deploy --target mycluster Coo.ear

Application deployed with name Coo.

Warning: Command _deploy did not complete successfully on server instance instance01: remote failure: Failed to load the application on instance instance01. The application will not run properly. Please fix your application and redeploy.

Exception while loading the app : EJB Container initialization error. Please see server.log for more details.

Warning: Command _deploy did not complete successfully on server instance instance02: remote failure: Failed to load the application on instance instance02. The application will not run properly. Please fix your application and redeploy.

On [server]: hostname:8080/FE-war/ all right.

On [instance01 the cluster] hostname:28080/FE-war

and

Answer 1

您的数据库/数据源配置不正确。它当前想要连接到

localhost:1527

上的数据库，但这意味着每个实例将尝试连接到其本地的数据库。显然这不是您想要的 - 您希望您的应用程序始终连接到同一个数据库，无论使用什么实例。

您需要编辑集群配置中的数据源以使用正确的主机名，以便每个实例连接到，例如，

dbserver:1527

，如果这是生产部署，请将数据库从 Derby 更改为其他数据库（例如 MySQL、 MariaDB、PostgreSQL 等）。 Apache Derby 不适合生产使用。

Answer 2

要在集群主机之一或运行的 DAS 主机上启动 derby 数据库服务器。

asadmin start-database

您还需要在管理控制台中重新配置 jdbc/__default 数据源的 URL。选择 DerbyPool 连接池的“附加属性”选项卡，并将 serverName 从 localhost 更改为启动数据库的服务器的主机名。
