Following:
1) a crash on 4th of April and a violent reboot of the ELLiOOs embeded machine
2) the need to recover the whole database files in the ELLiOOs embeded machine
the ElliOOs sofware was running back quickly. Though recently (in terms of working and available days) was reported that the tango DS was not communicating.
The reason why stayed misterious.
Following calls to Amplitude Laser (Vianney) last week and, today, a callabck from SCARELL (Romain and Jean-François), it is now understood that :
- the content of the data repository corresponding to the Tango gateway was not dynamically created (~/bin/ElliOOs/User/Data/28*/*). The specific file that was missing since the 5th of arpil reeboot was Plugin.sml.
Recovering this file and properly rebooting the embedded machine (from the ElliOOs programme running on the HOST, in the System Info --> reboot embedded), allowed to revoer the com.
Indeed it was checked by looking at jive by Falcoz.
An archive of the Code repository was done in case it is required to recover these files again. Archive sent to SCARELL.
Please remember to reboot the embeded in case there is a reoboot of TANGO machine in the main control room or if the database is reset.
Please also note that trying to look at the content of the TANGO_HOST variable in superuser or default user will not help in understanding if tango is running locally.
