Thank you.

Answer 1

When looking at the strace file the Driver Manager tries to load the odbc.ini you specified in your gateway init file: set ODBCINI=/etc/odbc.ini
but that fails as the oracle user can not access it - instead it tries to load a different file:
17811 open("/etc/odbc.ini", O_WRONLY|O_CREAT|O_APPEND, 0666) = -1 EACCES (Permission denied)
17811 open("/usr/local/unixodbc/etc/odbc.ini", O_RDONLY) = 8
Could you please make sure that the oracle user can access that file?
You also mentioned at the beginning that you could connect to the Postgres database using isql - did you do the test as "oracle" user and what ENV parameters have you set before opening isql?
Just a minor issue which has no impact as your LD_LIBRARY_PATH in the environment is set correctly - the listener.ora file contains the line
(EVNS=LD_LIBRARY_PATH=/usr/local/unixodbc/lib:/usr/local/pgsqlodbc/lib:/u01/app/oracle/product/11.2.0/dbhome_1/bin)
but EVNS should be ENVS or even better ENV. So please correct:
(EVNS=LD_LIBRARY_PATH=/usr/local/unixodbc/lib:/usr/local/pgsqlodbc/lib:/u01/app/oracle/product/11.2.0/dbhome_1/bin)
to
(ENV="LD_LIBRARY_PATH=/usr/local/unixodbc/lib:/usr/local/pgsqlodbc/lib:/u01/app/oracle/product/11.2.0/dbhome_1/bin")
Then stop and start the listener.
