Discharged - see software below. ACTION: RGM to try to identify an ADASS attendee to present a WFAU/WSA poster by the middle of next week. Discharged - MAR has agreed to go and fly the flag. ACTION: NCH to review the source/detection schemas one more time and make any necessary changes, and to read "SQL for dummies" (again) Discharged - small tweaks to SQL scripts have been made and checked in to the CVS. Actions partly discharged but continuing: ----------------------------------------- ACTION: PMW to apply a little presure to the premises team to solve the continuing problem of heat overload in C1. Some discussions with the IT Support team; temperature monitoring equipment has been installed in C1 to provide ammo for engaging with the premises people; action continues ACTION: ALL to review risk register and think of any new internal or external risks that should be documented in the risk register. Defered until top level plan is explicitly defined. PMW tabled the VISTA risk register as an example. ACTION: JPE to design and set up centralised VDFS web pages. Progressing. (there is now a link to it from our WSA Twiki). - continuing; thanks for progressing these. Actions carried forward from 06/08/04 meeting: ----------------------------------------------- None this week. Specific points and new actions: -------------------------------- Project management: NCH noted that longlisting for the astronomer/developer has now happened; thanks to AL & MJI for input (note after the meeting: PMW, NCH & RGM have assembled a shortlist of 5 candidates and one reserve; invitations for interview and reference take-up will start this afternoon). The longlist for the programmer/developer is currently being reviewed before shortlisting. NCH & PMW reported back from the VDMT meeting last week that WSA progress had been deemed OK. Comments and issues arising from CASU fortnightly minutes: No new minutes as of this week. Networking: ETWS reported that he will be attending the UKLight meeting at NeSC on Sep 9th to find out all about 10 Gbps end-to-end optical fibre networking. Hardware: NCH reported that the 4 channel RAID card seems to have settled down nicely; more than a terabyte of data shuffling has been done with no problems. The 8-disk backplane JBOD is in the process of being reintegrated in the rack mount cabinet of amenhotep and the full 32-disk U320 system will then be tested for stability. Software: MAR reported: "Wrote Java versions on the SLALIB functions I'm likely to need. Started writing WSA web pages, going with same/similar design as SSA unless objections. Re-factoring SQL servlets and asscoiated SQL retriever thread adding improvements and gettinng it to work with WSA. Look further into session tracking as could be used to track running queries and/or stop/warn users from having more than n queries running." Some discussions ensued concerning how much protection we should incorporate at this stage; there was general agreement that this should be included at this stage with some flexibility as to the value of "n" above. NCH & ETWS have been finalising CU1-4 with emphasis on clean exception trapping & logging and data integrity checks. Comprehensive database table constraint checking before committing ingest transactions is now implemented; any exceptions result in rollback of the ingest job to preserve the integrity of the data already in the archive. RGM suggested that some range checking should be done prior to ingest; NCH noted that this should be easy to do during the construction of the ingest files from the CASU FITS files. ACTION: NCH to remember to action a team programmer to implement range checking in the low-level ingest codes. SSA: No news (is still good news) this week; at some point soon the web access logs will be checked to compile usage stats. NCH noted that there has been no feedback from UKIDSS recently... Astrogrid deployment: No news this week. Miscellaneous: MAR reported submitting an ADASS abstract this week; currently no news as to whether this has been accepted but MAR has agreed to attend the meeting anyway.
