ApacheTK: Errors with the pig.pl workload in the white paper
Issue In the “Using HP-UX Workload Manager with Apache” white paper, in
section 13.4.0.7, the step using pig.pl to generate load, namely:
Then visit (several times, if necessary)
http://mymachine:8090/cgi-bin/pig.pl while watching the output of
wlminfo group.
may produce error messages and not generate the desired load. The errors
in /opt/hpws/apache/logs/error_log or /opt/hpws/apache/logs/error_log2 are of
the form:
[Sun Dec 14 16:03:08 2003] [error] 13441: ModPerl::Registry: No
comma allowed after filehandle at /opt/hpws/apache/cgi-bin/pig.pl
line 26.
or possibly:
[Sun Dec 14 18:02:40 2003] [error] 14688: ModPerl::Registry: Can’t
locate Apache.pm in @INC
<remainder of message removed>
These errors indicate that the Apache environment has issues with the
example mod_perl workload pig.pl.
Workaround Use a different mod_perl workload that you know works with your Apache
environment. Alternatively, focus on the .cgi and .php example workloads
used in the same section of the white paper.
WebLogicTK: javax/security/auth/callback/CallbackHandler error
Issue Monitoring a WebLogic instance with wlmwlsdc can produce a
javax/security/auth/callback/CallbackHandler error.
In particular, running the wlmwlsdc data collector with a single argument:
% /opt/wlm/toolkits/weblogic/bin/wlmwlsdc \
/home/wladmin/wlm/myinstA.props
on a version of WebLogic other than 7.0 can produce the following error:
Exception in thread "main" java.lang.NoClassDefFoundError:
