HP-UX Workload Manager Toolkits A.01.08 Release Notes for HP-UX 11i V1 and HP-UX 11i V2

Workaround If the ERROR message and the DEBUG message disagree, ignore the DEBUG message.
ApacheTK: Elapsed time reported may not be for a successful page fetch
Issue If you use the ApacheTK tool time_url_fetch with a URL that Apache cannot
serve (such as http://mytestmachine/misspelllllled_url.htm) the ab tool and
time_url_fetch report the elapsed time for Apache to serve up a “Not found”
msg. Neither tool considers this an error, although an individual trying to access
this URL might.
Workaround Always check your target URL by hand with your browser, the ab tool, and/or
the time_url_fetch tool to ensure you are really getting a page fetch.
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)
nl
http://mymachine:8090/cgi-bin/pig.pl
while watching the output of
nl
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
nl
comma allowed
after filehandle at /opt/hpws/apache/cgi-bin/pig.pl
nl
line 26.
or possibly:
[Sun Dec 14 18:02:40 2003]
[error] 14688: ModPerl::Registry: Cant
nl
locate
Apache.pm in @INC
nl
<reminder 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:
