General Tips

Where can I find the logs?

There are 2 different set of logs for GUMS: the client logs and the server logs. To solve some problems, you may also look in the apache logs (VDT installation only). The client logs are located in $VDT_LOCATION/gums/var/log for a VDT installation or /var/log for a manual installation. These logs cover the activities associated with the gums and gums-host commands:

• gums-developer.[USER].log
• gums-edg-security.[USER.log
• gums-privilege.[USER].log

Their location and information levels are controlled by the log4j.properties located in $VDT_LOCATION/gums for a VDT installation or /var/log for a manual installation. The server logs are located in $VDT_LOCATION/tomcat/v5/logs for a VDT installation or /var/logs/tomcat5 for a manual installation. These logs cover those activities using web services/ui:

• gums-service-admin.log
• gums-service-cybersecurity.log
• gums-service-edg-security.log
• gums-service-privilege.log

Their location and information levels are controlled by the log4j.properties located in $VDT_LOCATION/gums for a VDT installation or /var/log for a manual installation. The Apache logs are located in $VDT_LOCATION/apache/logs.

Access Problems

I keep getting AuthorizationDenied...

This occurs if you have not added your DN to the 'admins' user group using the 'addAdmin' tool or if the 'admins' user group is not added to the configuration with "write" access. This can also happen you if you use gums-host to retrieve maps that do not match the certificate host. A couple of other things to watch for are:

• If you encounter this in your browser, verify you are using the correct certificate.
• From the command line, verfiy you have a valid proxy (grid or voms) and it is for for the DN that is part of the admins user group.
• If you have access to the GUMS database in MySql, execute the following query: select userDN from User where userGroup = 'admins'.

I keep getting "An error accoured when connecting to GUMS: (0)null"

This is probably a problem related to apache in VDT: it doesn't accept GT3 style proxy. Check your apache log, you might find "Certificate Verification: Error (20): unable to get local issuer certificate". Try using "grid-proxy-init -old" when generating your proxy certificate.
