Another big problem is the workstation application upgrades. The NDS protocol version has been incremented, which means that all the NDS client applications have to be upgraded. The new dataviewer is working fine (on pianosa), but dtt is not:
controls@pianosa:~ 0$ diaggui
diaggui: symbol lookup error: /ligo/apps/linux-x86_64/gds-2.15.1/lib/libligogui.so.0: undefined symbol: _ZN18TGScrollBarElement11ShowMembersER16TMemberInspector

dtt (diaggui) and dataviewer are now working on pianosa to retrieve realtime data and past data from DQ channels.
Unfortunately it looks like there may be a problem with trend data, though. If I try to retrieve 1 minute of "full data" with dataviewer for channel C1:SUS-ITMX_SUSPOS_IN1_DQ around GPS 1019089138 everything works fine:
Connecting to NDS Server fb (TCP port 8088)
Connecting.... done
T0=12-04-01-00-17-45; Length=60 (s)
60 seconds of data displayed
but if I specify any trend data (second, minute, etc.) I get the following:
Connecting to NDS Server fb (TCP port 8088)
Connecting.... done
Server error 18: trend data is not available
datasrv: DataWriteTrend failed in daq_send().
T0=12-04-01-00-17-45; Length=60 (s)
No data output.
Alex warned me that this might have happened when I was trying to test the new daqd without first turning off frame writing.
I'm not sure how to check the integrity of the frames, though. Hopefully they can help sort this out on Monday. |
