Sometimes it’s time to upgrade. So the I decided to add the oracle 12c thin client to my mac a couple of weeks ago. Yes I know, I was very happy with the oldy-but-goodie 10g version, but ok.
The 12c instant client is very easy to install. I remember it took quite some time to install the 10g version, so happy about that. Unzipping the zipfiles, 2 symlinks and then a bit personal config in my .profile. So far so good.
But as soon as I started to use it, I was unable to connect to databases which had the SEC_CASE_SENSITIVE_LOGON parameter on true (the default) and I recommend keeping it that way. 2 weeks ago Oracle released a new version of their instant client and this problem is fixed!
The error which was thrown to you was:
ORA-01017: invalid username/password; logon denied
So if you encounter the same, check if your client was released before 14th of june 2016.
Only thing which still bothers me is that the thin client is missing a tnsping utility.
It works if you copy it over from the 10g version, but it’s not that nice.
