Use PyCoral for python menu access
Use PyCoral instead of direct oracle/frontier access for Menu-related queries in
The logic was also changed: now, during
load the code iterate through all available connection strings instead of retrieving the first correct one. This way the recovery is possible when the query fails during execution (for example Oracle grid error:
CORAL/RelationalPlugins/oracle Error ORA-12154: TNS:could not resolve the connect identifier specified (attaching a server 'ATLAS_COOLPROD')), not only during initialization.
TrigConfigAccessBase doesn't use
TrigConfFrontier class, but the Frontier access is managed by Coral.
New code was tested on lxplus, both for oracle and frontier credentials and on the grid https://bigpanda.cern.ch/task/?jeditaskid=28301388
Now a draft - was there a reason PyCoral wasn't used before?
