我在许多 OpenSUSE 论坛上搜索了这个问题的答案，但到目前为止我还没有找到。长话短说，当从 Oracle 安装 JDK 的 RPM 时，我收到以下信息：
> sudo zypper install jdk-8u111-linux-x64.rpm

请原谅我的冗长，我只是想让你看到的和我看到的一样。这是全新安装的 OpenSUSE Tumbleweed。
我还尝试在 OpenSUSE Leap 42.2 上全新安装它。在我第一次尝试之后，我在没有任何 Java 支持（没有 OpenJDK）的情况下重新加载，从头开始，就像我完成此安装一样。我专门按照在 OpenSUSE 上安装 Java 的指南进行操作。没有安装 Java 的、之前安装了 java OpenJDK 的、同时安装 JDK 和 JRE 的，无论出于何种原因，等等。
根据记录，Java 本身可以正常工作，但显然控制面板却不能正常工作。我尝试手动使用更新替代方案，我尝试从头开始编译，我已经重新加载，我已经从 Leap 切换到 Tumbleweed。以下是一些可能有用的其他信息：
> sudo update-alternatives --list java
/usr/java/jdk1.8.0_111/jre/bin/java
> sudo update-alternatives --config java
There is only one alternative in link group java (providing /usr/bin/java): /usr/java/jdk1.8.0_111/jre/bin/java
Nothing to configure.
> java -version
java version "1.8.0_111"
Java(TM) SE Runtime Environment (build 1.8.0_111-b14)
Java HotSpot(TM) 64-Bit Server VM (build 25.111-b14, mixed mode)
> javac -version
javac 1.8.0_111
我再次看到 Java 正在运行。但我仍然想了解为什么这个问题如此容易重现以及如何解决它。
答案1
执行此安装的过程比大多数人想象的要容易，令人惊讶的是，没有太多关于如何执行此操作的好的或直接的信息。上面的答案是正确的，但有些内容有点过时了。
下载Oracle JDK 1.8.0_151
#// rpm Installation Oracle JDK 1.8.0_151 wget --no-check-certificate --no-cookies --header "Cookie: oraclelicense=accept-securebackup-cookie" http://download.oracle.com/otn-pub/java/jdk/8u151-b12/e758a0de34e24606bca991d704f6dcbf/jdk-8u151-linux-x64.rpm运行安装命令
#// installation command rpm -ivh jdk-8u151-linux-x64.rp验证版本是否已根据您的偏好进行配置/安装

答案2
经过几个小时的努力，我终于解决了这个恼人的问题。
看来我们不能rpm -ivh jdk-8u121-linux-x64.rpm直接安装jdk，而是jdk-8u121-linux-x64.tar.gz手动下载并解压。
(JW 1/8/2017 修订) - 你实际上可以直接通过 rpm 安装，通过以下函数
#//rpm install
rpm -ivh jdk-8u151-linux-x64.rpm
大部分程序可以在这个网页，并且要小心你要安装的jdk版本。
以jdk-8u121 x64为例，我建议切换到根本原因，否则会有很多sudo：
1.下载jdk，选择jdk-8u121-linux-x64.tar.gz
http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
2.cd /path/to/downloaded/java
3.tar -xzf ./jdk-7uX-linux-XX.tar.gz
4.Open JDK 默认安装在 中/usr/lib64，因此我们/usr/lib64也将 Oracle Java 移至：
mv ./jdk1.8.0_121/ /usr/lib64/
5.创建一个符号链接/usr/lib64/jdk1.X.X_XX/（这对于稍后的更新很重要）：
ln -s -T /usr/lib64/jdk1.X.X_XX/ /usr/lib64/jdk_Oracle
6.压缩安装中涉及的 man 文件：
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/java.1)
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/keytool.1)
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/orbd.1)
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/policytool.1)
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/rmid.1)
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/rmiregistry.1)
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/servertool.1)
gzip $(readlink -f /usr/lib64/jdk_Oracle/man/man1/tnameserv.1)
7.准备jvm-exports目录，注意版本！
