perfSONAR User Q&A and Other Discussion

[Paul Gray <>]

Issues with incorrect file permissions on the distribution image seem to 
be resolved, but there are additional impediments to getting the SQL MA 
infrastructure plumbed up from the latest perfSONAR 3.3. MDM (Debian).

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:

  Aug 15 22:55:03 perfsonar jsvc.exec[3067]: e.#012

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?
