I have two different host name for same database sid. I used both host name in db details. But when I tried to select the entry from dash drop down, 2nd option blocked.
Could you please help me to resolve it.
dsn_tns = cx_Oracle.makedsn(db.host, db.port, sid=db.sid) conn = cx_Oracle.connect(user=db.user, password=db.password, dsn=dsn_tns)
