EF Core 3.1 - Exception when trying to use TnsAdmin

TridusAug 26 2020 — edited Sep 18 2020

I'm getting the following error when trying to set a TnsAdmin path: OracleConfiguration.TnsAdmin = @"c:\oracle\client\19c\network\admin";

System.IO.FileNotFoundException

This is a brand new ASP.net Core 3.1 project that isn't really doing much of anything yet. Scaffolding the dbcontext from the database works fine, however trying to run the project results in this error.

I've got the same thing in an ASP.net Core 2 project and that works without issue pointing to the same path, so I'm not sure what changed. I don't have an ldap.ora defined at all, and sqlnet.ora is as follows:

SQLNET.AUTHENTICATION_SERVICES= (NTS)

NAMES.DIRECTORY_PATH= (TNSNAMES)

SQLNET.CRYPTO_SEED = "X"

NAMES.DEFAULT_DOMAIN = X

NAME.DEFAULT_ZONE = X

Thanks

either there is Synchronization issue or
element which was there at time of recording is not there while playback ..could be defect

You should create a better custom dynamic variable to identify this element. Referencing a element by Index is not recommended or reliable. A recorded Index of 41 for the element inside form QUERYTEXTCOMPONENTS indicates that there are a lot of elements inside that recorded form, and that there is probably some dynamic nature to the page.

You should change the match to be i.e. formelement[INPUT](name="something" | id = "something")
