          Release News:
          1. gLite 3.0.2 PPS Update45 was released to pre-production last Tuesday.
            It is currently in phase of pre-deployment testing.
            The update contains:
            • YAIM module for 3.0 WMS to fix the bug of limit on uid for gridftp server
            All details in:
          2. gLite 3.1.0 PPS Update17 was released to pre-production last Thursday.
            It is currently being istalled at PPS sites after pre-deployment testing.
            The update contains:
            • glite-MPI_utils metapackage for gLite 3.1
            • Improved globus-gridftp startup script
            • various improvements for glite-info-provider-ldap
            • lcg_util v1.6.8 (SLC4)
            All details in:
        • <big> EGEE issues coming from ROC reports </big>
          1. (ROC France): This site had to change in emergency its domain name from "mrs.grid.cnrs.fr" to "in2p3.fr". A scheduled downtime is ongoing, but all old node names (and IPs) has already been replaced by the new ones into the GOC DB. During those operations, this site wondered whether this is possible or not to set an alias on a CE node. Is it possible ? Did any other site try this ?
          2. (ROC Russia): I would like to pay your attention at long and unsuccessful history of updates of lcg_util. The new one was issued for PPS. However, the update did not include the patch of lcg-rep and Classic SE (see bug #32999 in Savannah). However, this bug was fixed two week ago. Maarten Litmaath said that "release to production would be 1 or 2 weeks later" (see "Re: [LCG-ROLLOUT] RM SAM test on CE and Classic SE" in Fri, 8 Feb 2008). So, the sites which applied "update" as recommended operation procedure and still use Classic SE can not work properly during month or so. Is it really so complicated problem to rollback to situation before "updates"? Who can send a recommendation for site administrators to rollback manually at least? Btw, I think that the story like this may occur in future. I propose to think about rollback procedure on emergency. Manually or automatic.
          3. (ROC SWE): In the last days several sites in the SWE federations are experiencing problems with the Information System. Not clear wether this can be correlated with upgrading to the last version of the m/w or its yaim configuration. Want to raise this in the GridOps meeting to see if sites in other federations are seeing something similar.
