tomcat - 安装具有评估拓扑的 IBM Rational CLM 解决方案后服务器不会启动

Question

我一直在尝试使用评估拓扑安装和运行 IBM Rational Solution for CLM，以执行软件演示。

我能够继续完成所有安装步骤，但是一旦我到达启动服务器的步骤，它就不会启动。

当我尝试启动服务器时，一个新的命令提示符窗口打开，但立即关闭。/server/tomcat/logs 下的日志文件没有更新。

我最初是在 Windows 7 VMware 虚拟机中设置服务器。从那以后，我尝试在运行 CentOS 的新虚拟机中设置它，但我得到了相同的结果。

Answer 1

如 this thread 所示, 调试它的唯一方法是在起始脚本中放置大量的“echo”:

What really helped me when I had this problem was to add echo statements to the .bat files to see how far it's getting.
In my situation, it got all the way to the end of the catalina.bat file, and I printed out the final run commands on the screen.
When I called that same command manually in a dos window, I was able to see what error was being returned since it didn't close after a split second. Perhaps that approach would help you as well.

一般是内存问题。

如果不是 - 还有一些事情要检查:

1. Disk space - do you have much disk space available - esp. the location of your TEMP environment variable.
2. When Ralph talked about starting as Administrator - he meant starting your DOS shell using the right-button "Run as administrator" option on the shell.
3. Do you have any firewall settings preventing access to ports like 9443, 9080 and more obscure ones like 9003?
4. Does the user who installed RTC have read/write access to those c:\ibm directories and sub-dirs. I have seen Tomcat not start if it could not write to the log files (bit of a meaningless question as you have catalina logs).

That thread确认内存问题:

Please check https://jazz.net/library/article/811 for your patch level of the server OS. The document also points out 8GB RAM as a minimum.

If nothing appears in the logs it is a severe Tomcat or JVM issue. You may be facing RAM issues. i would suggest to look into the core dumps for indicators what happens.

Some other hints:

• Don't install in Program Files use /IBM/ or something
• If this is not a test system use DB2 instead of derby. Derby is only for demonstration purposes.
