Are you using Instant Client? What happens if you try the regular client? I hate Instanct Client...I seem to always run into issues like this with it.
Otherwise, verify your PATH environment variable points to the correct home.
I suggest removing the previous 12.1 client from the machine, with only one version of OCI.dll available there should be no confusion about which is loaded.
You did check that the 12.2 client has been installed correctly?
im not sure if its the instant, i dont get to pick what big work picks but it shows Administrator Client so i dont think its instant. I could be wrong. All the paths look correct, you know what im not sure if i rebooted since the push.
Not an option right now to remove 12.1 we are testing pki settings and if 12.2 hoses I cant be left without a connection to the DB's. I was advised by oracle we would be able to add ssl_version 1.2 or 1.1 with the 12.2 client. Not only did it not work now when i run scripts from the 12.2 client home i get prompted for a cert everytime the script hits a new db. Not cool when i have 36 the script runs through
Not an option right now to remove 12.1
Then at least remove it from the PATH, make sure only the 12.2 client tools are called and Toad sees only the 12.2 client home.
if reboot doesnt solve anything Ill try that because i do see it in there
