Tomcat 上使用 JNDI 的 IBM IMS 连接 - JAVA

【问题标题】：IBM IMS connection on Tomcat using JNDI - JAVATomcat 上使用 JNDI 的 IBM IMS 连接 - JAVA
【发布时间】：2017-12-07 07:29:39
【问题描述】：

我们正在从 WAS8 迁移到 Tomcat8。在Tomcat中，我们需要在Java中使用JNDI for IMS建立连接..

我在为 IBM IMS 的 JNDI 连接创建“URL”时遇到问题，下面是 IBM IMS JDBC jar 给出的 url 结构

对于 driverType 4 "jdbc:ims://datastoreServer[:port]/databaseName[:property=value;]";

对于 driverType 2 "jdbc:ims:databaseName[:property=value;]";

这是我创建的

jdbc:ims://xx.xx.xxx.com:4034;datastoreName=XXX34;dpsbOnCommit=true;

但在连接过程中出现错误

上面的问题看起来可以通过正确的 url 参数解决，但现在我遇到了错误

【问题讨论】：

  • 如果有人知道，请提供我的确切网址....
  • 错误消息很清楚：您使用类型 4 语法，该语法期望端口后面的数据库名称用斜杠 / 分隔 - 但您的文件中既没有斜杠也没有数据库名称网址。
  • 是的，我已经更新它 jdbc:ims://xxx.xx.com:4034/class://com.xx.xx.xx.application.S2U1LPSJDatabaseView:datastoreName=xx34;dpsbOnCommit=true ;完成此连接后，我认为没有给出任何错误，但由于 / 在 URL 之间，tomcat 没有启动并挂起……这是在我的 context.xml 中，并且由于 / tomcat 卡住了……知道如何克服

【解决方案1】：

对于 Type-4 连接 url：

jdbc:ims://datastoreServer[:port]/databaseName[:property=value;]

如果您使用的是 IMS 目录，则应将 databaseName 占位符替换为您的 PSB 名称

或与

class://your.fully.qualified.PSBNameDatabaseView

如果您使用的是本地元数据文件
