During DBCA create database received errors.
DBT-08001 Unable to check available memory
DBT-08002 Unable to get kernel parameter {0}
I'm installing on ORACLE 12.2 and Centos 7.1
Checked Doc ID 2261731.1 which refers to unset of ORA_CRS_HOME.
I did do an unset on this , but it does not exist in the "env" output.
Im not installing RAC, this is a stand alone database.
The machine name does not contain any underscores. utl-db-01.xxx.xxx
Received same error using the DBCA GUI which pointed to Oracle Out of the box templates as well as command line in silent mode.
