1.  VOMS related

1.1  VERR_DIR & VERR_SIGN

When you have the following errors: 

 Warning - Unable to submit the job to the service: https://wms.research-infrastructures.eu:7443/glite_wms_wmproxy_server
 Unable to retrive VOMS Proxy information: VERR_DIR

 Method: jobSubmit

 Switching to next WMProxy Server...

 Error - Operation failed Unable to find any endpoint where to perform service request

or 

Connecting to the service https://wms.grid.sissa.it:7443/glite_wms_wmproxy_server


Warning - Unable to submit the job to the service: https://wms.grid.sissa.it:7443/glite_wms_wmproxy_server
Unable to retrive VOMS Proxy information: VERR_SIGN

Method: jobSubmit

...

This happens becouse the glite-voms-server-config.py generates a "bad" file (/opt/glite/etc/voms/<VO>/voms.conf). To fix this "bug" edit the previous file, find the row with: 

...
--uri=<hostname>
...

and add to this line the voms service port (usually 8443). 

...
--uri=<hostname>:<port>
...

Finelly restart the service with: 

service gLite restart

And remember to re-generate the proxy certificate on the UI

1.2  Voms-admin

When ran as root, voms-admin uses the host credentials fount in /etc/grid-security. So you have to add this certificate as VO-admin:

/opt/glite/sbin/voms-db-deploy.py add-admin --vo <VO> --cert /etc/grid-security/hostcert.pem

2.  Cream CE

2.1  Integration between cream CE and pbs/torque

When you are installing a pbs/torque server in a location different that /usr/bin (the default installation path in glite torque rpms) you have to reconfigure the blah server to the new location.

Edit the file /opt/glite/etc/blah.config and change the values: 

# Path where pbs executables are located
pbs_binpath=PBS_BIN_LOCATION

[cut]

# Path where the pbs logs are located (for pbs $pbs_spoolpath/server_logs)
pbs_spoolpath=PBS_LOGS_LOCATION

Now, you have to restart tomcat 

service tomcat5 restart

2.2  Integration between cream CE and pbs/torque (using yaim)

Edit the file /opt/glite/yaim/defaults/ig-site-info.pre and change: 

#########################################
# Batch system configuration variables  #
#########################################

# The path of the lrms commands 
BATCH_BIN_DIR=<PBS_BIN_LOCATION>
