perfSONAR User Q&A and Other Discussion

[Fausto Vetter <>]

Hi Andy,

The error means you are not able to access the Exist Database. It seems
that during the configuration phase something went wrong. Did you follow
the procedure in the manual? You can check few things to ensure that the
database is working fine:

- Go to http://hostname/exist and go to the admin area (Administration
menu -> Admin)
- Login using the username and password that you created during the
perfSONAR RRD-MA configuration phase
- Go to browse collection
- choose rrdmaconfig
- see that the xml file you created is there and with the right
permissions (owner: rrdmaservice and group: dba)
- click on the xml file to see the file
- Finally logout the web-admin

If the configuration and stitching phases went fine, you should be able
to do these steps.

Also, go to the webadmin of the service
(http://hostname:port/geant2-java-rrd-ma/), go to advanced configuration
and check the following:
- component.ma.xmldb.db_uri
- component.ma.xmldb.db_username
- component.ma.xmldb.db_adminpassword
- component.ma.xmldb.db_password

These information should be correct.

The best way to get it running is to use the basic configuration steps.
Fill in everything properly and it should create everything. On the
worst case, uninstall and install it from scratch.

Any doubt, get in touch.

Cheers,
