1. Action Updates

- Action(94) - SystemLoggingDB example
Ongoing, will be discussed during the DIRAC week in June.

- Action(111) - File merging productions
Alexei should make use of the production API to generate productions from requests. 

- Action(116) - CPU studies
Roberto circulated a proposal from Steve Traylen, a summary of the LHCb requirements will be prepared by Ricardo 
and Roberto. ( ACTION: Ricardo,Roberto ) Ricardo has updated the new specint database with the results from his 
tests, ongoing. 

- Action(122) -  Develop specialized SAM Agent to track and report errors with regard to pilots
Ongoing.

- Action(132) - Update LFN construction utility to store prod output directories as a parameter
This is now possible after the recent production API developments, will be done this week. 

- Action(133) - RequestDB monitoring
Not yet ready after comments from Andrew. 

- Action(134) - Provide RunDB monitoring page
Ongoing. 

- Action(139) - gLexec testing after deployment at new sites
Stuart will begin testing at IN2P3 after discussions with Roberto.  

- Action(140) - Banning faulty storage elements
Ongoing.

- Action(144) - BK input data queries 
The BK updates are available, Andrew and Andrei must update the agents where this is used. ( ACTION: Andrew, Andrei )

- Action(145) - SAM production vs. sgm
Action reformulated, new test required. 

- Action(147) - New machine available
Ricardo circulated a proposal for partitioning the disks on the machine.  Joel confirmed that this was possible with IT 
but will take a long time to arrange so it was agreed to continue with what is available, action closed. 

- Action(148) - Setup DIRAC SVN/Trac project portal and configure access to the DIRAC developer team
Ongoing. 

- Action(149) - Test the --use-grid SetupProject option to set the LFC_HOST to be used by CORAL with Merging jobs
Closed last week.
