c# - asp.net application not connecting to oracle 11g even after installing oracle instant client for 11g -


i have asp.net mvc application using oracle 11g database. in development machine every thing worked fine, while deploying in production server asp.net application not able connect database server. throwing empty exception.

i wrote simple console application test db connectivity. not working. realized because machine doesn't have oracle client installed. installed oracle instant client 11g database 32 bit version. after console application started working web application still not connect.

i google lot , decided analyse using process monitor. in process monitor found web application (iis) looking oraclient12.dll.

this oraclient12.dll part of oracle client 12c database. can't understand why looking dll.

enter image description here

after installing oracle database client 12g, above issue oraclient12.dll got fixed. iis not able locate oraclsce12.dll. searched whole file-system file not find.

does know should install oraclsce12.dll.

thanks, sujith

i facing similar issue, came know dll installed should install option «oracle advanced security»,, choosing custom installation when installing oracle 12 client. did same , issue got resolved. can try , see if issue gets resolved.

thanks sudharsan
