Subject RE: [EXTERNAL] Re: Problem starting Tomcat 7.0.59 as a Windows Service
Date Tue, 12 Jan 2016 16:04:31 GMT
I used the Java options provided by IBM.  Since Tomcat will successfully start using the startup
batch files, I assume that these settings are fine.  I've tried playing with the settings
and cannot get it to work either.  I seems like it's some sort of weird Windows thing.

I have successfully configured these services before with prior version of IBM's CLM.  The
difference in those previous versions was that Tomcat came bundled with t heir product.  For
this latest IBM version, Tomcat was not bundled and they provided instructions for downloading
it from Apache and instructions for where to install it.

I have escalated the issue with IBM's support and since they are providing the JVM, it is
probably their issue but wanted to put it out to the larger community to see if anyone has
ever had this issue before.  A user on the user forums said that the memory error in the Tomcat
log file is a red herring and that it is giving that memory allocation error because the JVM
didn't actually start.  So, the issue seems more connected to the error in the Windows Event
viewer ("cannot open file").

 Tomcat starts as well as all of the IBM CLM applications.

 I have followed the instructions provided by IBM:

Note that, depending upon how you set the CATALINA_HOME environment variable, rebooting will
lose this value. I'm not sure the reboot was necessary.

That's a BIG buffer. Do you need 1G NIO buffers? A web-based video-editing application?

What is -Xmn? It's probably not a problem, but I thought I'd point-out something that looks

 I thought I would submit here to see if it could be a Tomcat service issue specific to Windows.
 Here is my host information:

to "PROGRA~1".  When I installed the service, I ran the install from a Windows Command Prompt
that I opened using "Run as Administrator".

Has anyone ever run into this?

Is it possible that you have the 32-bit service runner? That would cause the JVM to run in
32-bit mode when you launch as a service. Selecting the JVM DLL directly should definitely
select the right JVM (and
architecture!) but I'm not an expert on Windows and Windows Services.
