Oracle 23ai: How to create DB in silent mode

On this activity we are going to create a DB in silent mode.
We don’t have GI on this environment and since software has been only released for Engineered Systems, we need to create with “_exadata_feature_on=true”

[oracle@ol8_23ai ~]$ cd /u01/app/oracle/product/23ai/db_home1/bin	 
[oracle@ol8_23ai bin]$ ./dbca \
     -ignorePreReqs \
     -ignorePrereqFailure \
     -silent \
     -createDatabase \
     -templateName General_Purpose.dbc \
     -sid dbtest23 \
     -gdbName dbtest23 \
     -SysPassword syspassword \
     -SystemPassword systempassword \
     -storageType FS \
     -datafileDestination /u02/database \
	 -archiveLogDest /u02/database/DBTEST23/archivelog \
	 -enableArchive true  \
	 -numberOfPDBs 1 \
	 -pdbAdminPassword pdbadmin \
     -pdbName dbtest23pdb1 \
     -initParams db_unique_name=dbtest23,sga_max_size=1500M,sga_target=1500M,pga_aggregate_target=200M,_exadata_feature_on=true

DB created:

Note that on 23ai, you are forced to have PDB’s. There might be some trick to be a non-cdb, but did not find it yet. Will provide how to do it if I find it.
