2. Changes in this release

2.1. Changes in functionality

The DGAS Client has been added to interact with a DGAS Server
The information provider for the Condor batch system has been added
A new array parameter (voms.cert.url) has been added to specify the URLs of the certificates of VOMS Servers hosting the VOs supported by the CE node
A new array parameter (custom.runtime.environment) has been added to allow setting custom GlueHostApplicationSoftwareRunTimeEnvironment entries in the CE info provider file
Version 6.7.10 of Condor is required by this release of the CE service

2.2. Changes in Configuration

The following new parameters have been added to the glite-ce.cfg.xml file:

Parameter name	Default value	Description
voms.cert.url	<changeme>	URL from where the VOMS server certificate public key can be downloaded for each VO listed in the voms.voname parameter. If no URL is available for one or more VOs, set the corresponding value to empty string [Example: http://www.nikhef.nl/VOMS/kuiken.nikhef.nl.pem] [Type: 'string']
custom.runtime.environment	<empty>	The entries specified in this array parameter are added to the CE info provider file as additional GlueHostApplicationSoftwareRunTimeEnvironment entries. [Example: MY_APP_1_0_0] [Type: 'string']

The following parameters have been changed in the glite-ce.cfg.xml file:

Parameter name	Old value	New value	Description
condor.version	6.7.9	6.7.10	The version of the installed Condor-C libraries
condor.releasedir	/opt/condor-6.7.9	/opt/condor-6.7.10	The location of the Condor package. This path is internally simlinked to /opt/condor-c. This is currently needed by the Condor-C software

5. Known bugs and issues

This release has the following bugs and issues. Bug numbers refer to the gLite Bug Tracking system database hosted on the CERN Savannah system at https://savannah.cern.ch/bugs/?group=jra1mdw .

Currently jobs get a full proxy rather than a restricted one as done in LCG. This is needed for multi-hop submission (as e.g. to condor pools but also eventually for CE – CE submission) and apparently GT4 abandoned support for restricted proxies. Security implications need to be better understood. Currently being discussed in the MWSCG (Bug 7425)
During the execution of the CE configuration script, a number of Globus configuration scripts are executed. One of these scripts outputs the following error (BUG #5992):

[…]

running /opt/globus/setup/globus/setup-globus-gram-reporter-fork..[ Changing to /opt/globus/setup/globus ]
Setting up fork gram reporter in MDS
-----------------------------------------
Error fork GRAM reporter entry jobmanager-fork. Aborting!
ERROR: Command failed

[…]

This error doesn’t affect the correct functionality of the CE and can be ignored.
This release include a tech preview of the GT4 Workspace Service that can be used as an alternative to the pool accounts method for creating and configuring the user execution space. This preview can be activated by using the alternative configuration script glite-ce-wss-config-py. This script requires Apache Ant v. 1.6.1 or greater to be installed and properly configured on the server. Please refer to the Apache Ant user manual for the details
No removal procedure is provided with this release apart from the removal of the RPMS. Any account, group or other resource created during the module configuration must be manually cleaned up.
