XBaya load problem

XBaya doesn't seem to launch properly coming straight out of the box (as part of OGCE).

PROBLEM:
I keep getting the following:
An error occurred while launching/running the application.
Category: Launch File Error
The field codebase has an invalid value: @HOST_BASE_URL@/xbaya/

I tried changing the value of "@HOST_BASE_URL@" to "${host.base.url}" in xbaya.jsp and xbaya.jnlp (in portlets/xbaya/src/main/webapp), but this yields pretty much the same problem.

SOLUTION:
In tomcat/webapps/xbaya/ open up xbaya-final.jsp and xbaya.jnlp, change "@HOST_BASE_URL@" to "http://localhost:8080".

Proxymanager GFAC credential problem

To try and resolve the proxy credential mismatch between proxy-manager portlet and gfac, I tried just manually deleting the following two jars from gfac deployment directory:
  • cog-jglobus, version: 1.2-050621
  • proxymanager-api, version: 4.3
No longer am I getting the old error (from GFAC Portlet) that I use to be getting - related to the portlet not being able to get a proxy credential, now I have a new problem when I first obtain a credential from proxy-manager and then try to open up gfac:

xsul.XsulException: The credential is not a Globus credential. at xsul.invoker.gsi.GsiInvoker.createPuretlsContext(GsiInvoker.java:51) at xsul.invoker.gsi.GsiInvoker.(GsiInvoker.java:43) at

MySQL won't start problem

Was trying to run MySQL, but came across a really annoying problem - it kept saying it couldn't find a "socket" file and thus wouldn't start.

eg.
> mysql
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2)

Here's how to fix it, just start the MySQL daemon again and all will work:

Grid FTP / MDSS testing

Time has come to test the file-manager portlet once again. I'm using the same "MDSSLoadTesting.jmx" file as before, just with slightly bigger files this time.

I have downloaded the files, and just need to run the test within JMeter. I need to add three accounts however to the OGCE portal: ogceUSER1, ogceUSER2, ogceUSER3.

Find out if something is running on port 8080

For my remote NMI builds, there is a problem I am facing that the portal I am building won't start on port 8080 because it is "being used by" something else.

Here's a test you can perform automatically to verify if the port is indeed being blocked, and by what (use the "lsof" command). By the way this doesn't actually help me any for my NMI builds since the NMI machines don't have the "lsof" command.

echo -------- IS THE TOMCAT PORTAL ALREADY RUNNING, OR IS PORT 8080 BEING USED? ---------
# COMMAND TO FIND OUT WHAT IS RUNNING ON PORT 8080
lsof -i :8080


if test $? -ne 0; then
echo " => PORT 8080 IS FREE, NO PROBLEMO"
else
echo " => PORT 8080 IS BLOCKED, TRY SHUTTING DOWN TOMCAT SERVER"
portal_deploy/apache-tomcat-5.5.12/bin/shutdown.sh
fi

OGCE Local build/run tests almost done

The build and JMeter run tests for the OGCE portal are almost done. I've got a script finished that builds the portal from scratch, runs the JMeter tests, and sends all the result files to SVN.

Things to do:
  1. Try somehow to show the HTTP response errors for the JMeter modules that failed
    1. Maybe give a URL link to the errors within the XML document?
  2. Highlight the tests that failed within the XML document (via XSL stylesheets!)

Adding XSL stylesheet info line on second line of XML document

Solution for #1:
Clip the ?xml...? first line from the XML document, and copy the rest of the XML file into a temporary file. Then insert XSL tag-sheet info as well as the XML document header (which you clipped) into the original file (overwrite the file). Finally, append the temp file's contents to the original file and voila! You've inserted the XML stylesheet info on the 2nd line of your file!

num_of_lines=`cat OGCEJMeterResults.xml | wc -l`

tail -n $[$num_of_lines - 1] OGCEJMeterResults.xml > OGCEJMeterResults-temp.xml

echo (THE XML AND XSL HEAD TAGS HERE) > OGCEJMeterResults.xml

cat OGCEJMeterResults-temp.xml >> OGCEJMeterResults.xml

rm OGCEJMeterResults-temp.xml
