Very strange situation here. We upgraded from 11.2.0.4 to 12.2.0.1, everything seemed to work fine. Then one of our developers installed the new 12 client, and they cannot connect to the 12 database. They can still connect with the 11 client, though. We've watched the listener log and it appears that the connection is coming thru the listener with no problem, but gets lost somehow before it shows up in the database. Looking in the audit trail, the session never seems to show up. The error code is ora-12637.
No user running the 12 client can connect.
Not sure what all is needed, but here's our information
HP-UX
Current July patchset installed.
Our sqlnet settings are:
NAMES.DEFAULT_DOMAIN = ****.****.****
SQLNET.EXPIRE_TIME = 10
SQLNET.INBOUND_CONNECT_TIMEOUT = 45
automatic_ipc = on
SQLNET.ALLOWED_LOGON_VERSION_CLIENT=11
SQLNET.ALLOWED_LOGON_VERSION_SERVER=11
SQLNET.SSLFIPS_140 = TRUE
Processes in the database are set to 300.
Not sure what else is needed.
Thanks
