When installing the db2 probe, even though the software and hardware requirements are met, the probe fails with the following message in the controller.log:
Controller: Max. restarts reached for probe 'db2' (command = db2_monitor)
The output of the commands './db2_monitor' and 'ldd db2_monitor' ran in the db2 probe directory points towards a missing library:
'./db2_monitor: error while loading shared libraries: libdb2.so.1: cannot open shared object file: No such file or directory'
This library libdb2.so.1 is located separately from the other libraries.
Therefore, the environmental variable within the Robot controller needs to point to this location for the probe to be able to activate.
