1) You can create them all using setup - use the ConfigFile directive:
https://access.redhat.com/knowledge/docs/en-US/Red_Hat_Directory_Server/9.0/html/Installation_Guide/Advanced_Configuration-Silent.html#Using-ConfigFile-for-DS-Config

1.a) copy/paste the contents of 
/usr/share/dirsrv/data/template-suffix-db.ldif and edit it - replace 
%ds_suffix% with your suffix DN, and replace %ds_bename% with the 
database name e.g. ihcComRoot

1.b) setup-ds.pl ..... slapd.ConfigFile=/path/to/file.ldif

you can also feed that file into ldapmodify
