TDI V 7.1.1: how to update local jvm
问题
我负责在客户现场维护一个 TDI V 7.1.1 安装。TDI 本身是由他人在4年前安装的，因此我不知道当时的安装方式，只能看到结果。
我需要在不久的将来安装最新的修补程序包 9；为此，我在一份IBM 支持页面上找到建议同时更新 TDI 使用的 JVM。
在客户的服务器上，我发现 TDI 正在使用本地安装在以下位置的 jvm
> \TDI\V7.1.1\jvm\jre
该机器上没有独立的 JVM / JRE 安装。运行以下命令
.\java -version
我发现这个 JVM 的版本是 1.6.0。现在，上面提到的 IBM 支持页面告诉我不再支持 Java 6。在该页面底部还有另一个链接，介绍了 Java 7 或 Java 8，但那只会把我带回另一个通用的 FixCentral 搜索页面。
问题是：
我如何将本地的 JRE 从 Java 6 升级到适当的版本（最好是 Java 8）？

I'm responsible for maintaining a TDI V 7.1.1 installation at a customer's site. TDI itself was installed over 4 years ago by someone else, so I don't know exactly how the installation was done back then; I just see the results.
I need to install the latest fixpack 9 in the near future; in preparation of this I found an IBM support page recommending to also update the JVM used by TDI.
On the customer's server I find that TDI is using the jvm installed locally below
> \TDI\V7.1.1\jvm\jre
There's no independant JVM / JRE installed on that machine. Calling
.\java -version
I found that this JVM is V 1.6.0. Now, the above mentioned IBM support page is telling me that Java 6 is no longer supported. Near the bottom of that page is another link talking about Java 7 or Java 8, but that only leads me back to another generic FixCentral search page.
Question is:
how can I upgrade just that local JRE from Java 6 to whatever is suitable (preferably Java 8)?

自己找到了答案；经过10多次尝试在IBM的“FixCentral”网站上提交下载请求，我终于成功访问到了适当的IBM页面，链接到了来自FixCentral的下载包（7.2.0-ISS-SDI-LA0019）；哎呀，这真是一团糟……
该包含有一个README文件，详细说明了如何进行更新。
所以，对于所有感兴趣的人，我问题的答案是：
-
是的，如果我们有IBM修改过的JRE包，我们可以进行更新
-
一定要仔细阅读README，特别是涉及java.policy修改的部分
英文:
Found the answer myself; after 10+ attempts to place a download request at IBM's "FixCentral" site I finally managed to get to the suitable IBM page linking to the download package (7.2.0-ISS-SDI-LA0019) from FixCentral; oh dear, this is really a mess...
The package contains a README giving exact instructions on how to update.
So, for everyone interested the answer to my question is:
-
yes, we can update if we have IBM's modified JRE package
-
be sure to study the README esp. the part dealing with java.policy modifications
