perfSONAR User Q&A and Other Discussion

[Lukasz Lopatowski <>]

Hi Paul,

Sorry for the late response.

As far as I know, the deployment test run from the Web Admin page may not work correctly in case of SQL MA service.

You can verify the installation by sending the EchoRequest from the perfsonarUI tool as described in [1] under Testing your deployment section.

I will also forward your concerns to SQL MA service developer.

Greetings --- I apologize for the repeat inquiry, but was wondering if anyone had an update.

Specifically, by any chance has someone verified that the SQL MA can successfully be deployed with the perfSONAR 3.3 MDM image?  I've heard of several people reporting failures off-list and was wondering if anyone has been able to finish the plumbing of the the SQL MA configuration with the latest Debian-based DVD iso.

Issues with incorrect file permissions on the distribution image seem to

This problem is persisting, and so am I, I guess...apologies for being
the squeaky wheel.

Can anyone verify that the SQL MA (tested from the web interface sanity
check) is ever able to return a successful check on the latest perfSONAR
3.3 MDM Debian install image?

I'm not doing anything out of the norm in the installation. I'm just at
a loss to see where, if it can be installed from the latest image, I
might have deviated from the instructions in the Administration Guide.

My configuration is that of a combined LS, RRD MA, and SQL MA options,
chosen from the MDM installer's options.

I can ping the SQL MA service using the perfSonarUI. However the
deployment test provided on the web frontend for the SQL MA fails.

Looking at the logs, it appears that the cause is missing xml files...
The ping request and response files aren't where the web frontend
scripts are expecting them to be:

Aug 15 22:51:51 perfsonar jsvc.exec[3067]:
java.io.FileNotFoundException:
/var/lib/tomcat5.5/webapps/geant2-java-sql-ma/WEB-INF/samples/requests/EchoRequest.xml

(No such file or directory)

I copied over the EchoRequest.xml from the rrd area:

mkdir -p
/var/lib/tomcat5.5/webapps/geant2-java-sql-ma/WEB-INF/samples/requests #
The directory didn't even exist
cp
/usr/lib/perfsonar/services/perfsonar-java-rrd-ma/WEB-INF/samples/EchoRequest.xml

/var/lib/tomcat5.5/webapps/geant2-java-sql-ma/WEB-INF/samples/requests/

But then, the EchoResponse suffers from the same missing components:
Aug 15 22:53:55 perfsonar jsvc.exec[3067]:
java.io.FileNotFoundException:
/var/lib/tomcat5.5/webapps/geant2-java-sql-ma/WEB-INF/samples/responses/EchoResponse.xml

(No such file or directory)

I again copied over the files from the rrd area:
mkdir -p
/var/lib/tomcat5.5/webapps/geant2-java-sql-ma/WEB-INF/samples/responses
cp
/usr/lib/perfsonar/services/perfsonar-java-rrd-ma/WEB-INF/samples/responses/EchoResponse.xml

/var/lib/tomcat5.5/webapps/geant2-java-sql-ma/WEB-INF/samples/responses/

Now I'm at the point where the *web frontend* test fails, even though
the logs show the test being successful:

Notice the "This is the success echo response..." in the logs above.

So the logs are showing that the EchoRequest/EchoResponse succeeds, but
the web administration frontend test still fails, and to reinstall
tomcat and the web service.

Where might I look further to find the culprit causing the web
frontend's SQL MA test to fail?
