To view the docs you indeed need the client support identifier,
but for your quick reference...
The DB Support for last version of ATG 9.4
Oracle 9i, 10g, 10g RAC, 11g, 11g RAC, Exadata (Oracle Exadata hardware versions X2-2 and X2-8 and above)
MSSQL Server 2005 SP3
MySQL 5.5.11 (dev only, JBoss only)
The DB Support for ATG 10.0.3.2.
Oracle Exadata, 10gR2 (10.2.0.3), 10gR2 RAC (10.2.0.3), 11gR2 (220.127.116.11.0), 11gR2 RAC (18.104.22.168.0)
IBM DB2 9.7.2
MSSQL 2008 SP1
MySQL(Dev Only) 5.5.11
If I get it right and informing what is explicitly described in docs
so you need to have at least the ATG 10.0.x for Oracle 11G R2
and 10.0.3.2 for Exadata (X2-2 and X2-8 and above) with 11G R2.
