Hi Clay,
Yes, I had the same problem:
https://twitter.com/xtner/status/1235918336241868802
Oracle windows clients 19.3 and 19.5 fail to connect to Oracle 19.3 with"ORA-12637: Packet receive failed". Oracle clients <19 work fine... and i
We have a 19c (19.1) database in “bare metal Azure” that I’m trying to
access with TOAD or SQL*PLUS and the Oracle 19c (19.3.0.0) client. I keep
seeing an ORA-12367 (Packet receive failed) error. SQLDeveloper can
access (using TNS) just fine.
If I try with the Oracle 12 client, everything works perfectly.
I just did a quick search of MOS and couldn’t find anything; so I’ve got
an SR open; but also wanted to see if anyone here has seen the same thing.
