I am in the process of upgrading TOMCAT on our z/OS systems.

I haven't gotten too far..... setup all parms and am trying to bring up manager.....

One of of my z/OS systems, it starts fine, although I do get the following warning:

WARNING: ÝSetPropertiesRule¨{Server/Service/Engine/Realm} Setting property 'resourceName' to 'UserDatabase' did not find a matching
property.

But.... when I use the exact same startup parms (and everything else) on a different system, I get the following error and it shuts down:

Nov 16, 2009 1:52:49 PM org.apache.catalina.startup.Bootstrap initClassLoaders
SEVERE: Class loader creation threw exception
Throwable occurred: java.lang.NoSuchFieldError: org/apache/catalina/startup/ClassLoaderFactory.IS_DIR


Any ideas ?

Terry

When I compare, line by line, the STDOUT from the successul start (versus the bad one), I see the following lines when the output stops matching.....

class load: org.apache.catalina.startup.CatalinaProperties from: file:/opt/fitb/jakarta-tomcat-6.0.18/bin/bootstrap.jar
class load: org.apache.catalina.startup.ClassLoaderFactory from: file:/opt/fitb/jakarta-tomcat-6.0.18/bin/bootstrap.jar
class load: org.apache.catalina.loader.StandardClassLoaderMBean from: file:/opt/fitb/jakarta-tomcat-6.0.18/bin/bootstrap
.jar class load: org.apache.catalina.loader.StandardClassLoader from: file:/opt/fitb/jakarta-tomcat-6.0.18/bin/bootstrap.jar

Only the 1st two are present in the unsucessful run....... not the last 2.

Definitely weird....

Terry

Are you somehow mixing in multiple versions of Tomcat in your classpaths? Are you using the T:Z Tomcat distribution?

No... I shouldn't be...... The HFS files, where the older version resides, is not even mounted...

If it works on one system (LPAR), it should work on another.

i am using the same parameters, HFS file, start command, etc...

Definitely weird, but so far I can only run on one system.

Terry

Are you using our t:Z Tomcat distribution? Same SDK version on both LPARS?

If you would like, run with LOGLVL='+D' and email the complete job output to info@dovetail.com and we'll try to take a look.

Yes... using t:z .... and both LPARs should be the same.

Where do I put the LOGLVL='+D' ?

Terry

LOGLVL is a parameter in the sample TCPROC jcl that we ship with t:Z. It turns on the logging level for the JZOS batch launcher.

Just to followup - this problem turned out to be an issue the the SDK 6 shared class cache. Clearing the cache and restarting solved the problem.

Yes..... thanks for the assist !
