Your assistance is greatly appreciated.

I can't help you with your z17, but that tomcat version you are using
was released over two years ago ([0] 2023-08-25), you should not run
this anymore imho.

Hello,

There is no processor specific code that needs changing for the IBM z17,
thus ensuring the existence of a Java 11+ runtime, Tomcat 10.1.13 will run
as is.
The only risk is running an old Tomcat version that is missing recent
security patches. Latest released version is 10.1.44.

Kind regards,
Dimitris

  for
any configuration needed.

Kind regards,
