            • yaim-core update
            • support for SGE CEs
            As there is an update of YAIM core *all* metapackages are reported as affected by this update

        • <big> EGEE issues coming from ROC reports </big>
          1. (ROC CE): There is a GGUS ticket from Central European site related to inconsistencies in DPM assigned to ROC CE. Some files are in DPM DB but not on the disk. We would suggest to remove files manually from the DPM DB to clear inconsistencies, but we are not sure if we should inform VO(s) about such changes and what is the procedure in case files are lost? For reference, the ticket link: https://gus.fzk.de/ws/ticket_info.php?ticket=33012
          2. (ROC CE): WARSAW-EGEE site experiences problems similar to those of FNAL which resulted in action 101. WARSAW-EGEE is interested if there is any progress on the issue. They have in place standing reservation for OPS VO jobs which however did not help to avoid problems with RM test timeouts.
          3. (ROC SEE): While working on registration of new Serbian EGEE site (AEGIS07-PHY-ATLAS), we encountered the following problem in GOCDB, which does not recognize existing country reps for newly created sites: https://gus.fzk.de/pages/ticket_details.php?ticket=32910
        • <big> gLite Release News</big>
          1. release of gLite 3.1 Update14 to production in preparation. The update, to be released very soon (within Wednesday), will contain:
            • YAIM module to configure LCG CE and gLite WN for MPI support according to the guidelines from the EGEE TCG working group on MPI
            • Additional MAUI package (better support for the split of CE from Torque server)
            • Improved globus-gridftp startup script
            • lcg_util v1.6.8
            • Improvements to glite-info-provider-ldap
            • glite-yaim-core 4.0.3-13 for gLite 3.1
            As there is an update of YAIM core *all* metapackages are reported as affected by this update. Actually the yaim-core was changed sue to an incompatibility found in PPS with the released version of the glite-info-provider-ldap, so the list of impacted services can be restricted to those concerned by the new version of glite-info-provider
          2. Release of gLite 3.0 Update40 to production in preparation. The update, to be released very soon, will contain:
            • YAIM module for 3.0 WMS to fix the bug of limit on uid for gridftp server
        • <big>64 bit update </big>

        • <big>YAIM exit codes</big> 5m
          We r about to implement YAIM exit codes, error codes, and associated error messages, in order to help a bit the interaction between YAIM and fabric management systems. In principle it will conform with /usr/include/sysexits.h and some additional own exit code all below 126. If you are using some tool (ex. quattor) which could make use of this feature, and/or you have advice/opinion how you would like to see this to be implemented, please shout now ! And instead of flooding Rollout please send it to yaim-contact@cern.ch thx, Gergo
