- Changing IP addresses & DNS (DNS updates)
- ATLAS are considering increasing the limit of their ESD file size from the current 10GB to 15GB (or 12GB at least). Would this create any problem at sites?
- ATLAS job recovery now appears to be working well - allowing jobs to finish even if the SE is not up/unstable when the job finishes (see ATLAS subsection).
- A recent SL5 update (to python and its libraries), now in fnal and cern repositories, broke running ATLAS jobs last week.

Wednesday, 6th June
Released a document, hep.ph.liv.ac.uk/~sjones/VomsSnooper.odt, that describes how to
- Maintain site VOMS info document for the approved VOs
- Check a site's VOMS records correspond exactly with CIC portal
- Create new site VOMS records direct from CIC portal, without manual transcription
Note: I'm accepting tips from GridPP core task members etc. about other use cases for these processes. This will be converted to wiki formatted and made available in the normal way.
Next jobs:
- review logical/sequence of VOMS admin process, document it if it works, fix it if it doesn't.
- create standard baseline for proxy renewal process, and write it up in wiki.
Note: I'm accepting tips from other Gridpp core team members etc. for document priorities. Please think
about where the problems lie (i.e. what costs us yet is easy to fix) and get back to me.
Tuesday, 29th May
- VOMS Records in GridPP Approved VO list now up to date with CICs Portal XML. This can be used by Site Admins to ensure their site-info.def/vo.d directories are up to date. A tool, SidFormatter, will be released this week to facilitate comparison with the benchmark. A process has been devised to ensure that GridPP Approved VO is kept up to date to within a week of CIC Portal changes. Consultation to be made about further fields that we may wish to advertise in this manner.
Friday 27th April
- Appeal for a volunteer to enhance "Grid User Crash Course" (https://www.gridpp.ac.uk/wiki/Grid_user_crash_course) with simple use case for dependable proxy renewal for long jobs, as this is a recurrent requirement that has caused multiple queries on TB_SUPPORT.

Monday 18th June
The EMI 1 updates are just minor revisions: Top BDII, BLAH and Storm. A repackage for GFAL/lcg-utils to handle the globus lib dependancy problems. Further EMI-2 updates, probably of interest only for those doing EA of them.
- Staged rollout: Lot's of EMI-2 packages, working their way through the verification/SR process. The software that is just a repackage from EMI-1 to EMI-2 are skipping SR on SL5 - the SL6 versions will be tested. Most of the products in SL5, support upgrade and reconfiguration from the EMI1 versions.
- Note that CREAM is one of the products that can't to an inplace update - new DB schema, so needs a drain/wipe/re-install.
- Question from Tiziana - anyone using CREAM in Cluster Mode? Any feedback on that?

Monday 25th June - JW
- Only one issue of note this week, namely I could not close the Cambridge ticket despite it being solved in GGUS. After filling in all the form data correctly, adding in the solution, setting the ticket to "solved" in the dashboard, the dashboard still complained that I had not filled in "something" with correct data. I extended the ticket by 1 day, and was able to close it the following day by (having entered in the same data). Anyhow, it is an unrepeatable bizarre and annoying problem.
