(Doc ID 2003316.1)
Last updated on JUNE 18, 2024
Applies to:
Oracle Database Appliance Software - Version 2.1.0.1 to 12.1.2.12 [Release 2.1 to 12.1]Information in this document applies to any platform.
Symptoms
This note describes various situations when ODA users might encounter SSH problems. Usually seen during maintenance, patching, upgrades or other administrative tasks using oakcli.
Often the problem is associated with root executing oakcli commands which in can trigger several scripts in the background which require SSH for root, grid and Oracle users.
The actual source can be misleading, however, as discussed in the following note:
from ODA: Oakcli Create Database Fails with Error in authorized_keys (Doc ID 1674279.1)
"...The following error encountered while creating database using oakcli..."
