6 10g Release 3 (10.1.3) Version Compatibility

Oracle Application Server 10g Release 3 (10.1.3) is designed to be installed in parallel to your existing Oracle Application Server installations. For example, you can install a new 10g Release 3 (10.1.3) Oracle home on a host where you have already installed Oracle Application Server 10g (9.0.4) or Oracle Application Server 10g Release 2 (10.1.2).

Oracle Application Server 10g Release 3 (10.1.3) does not require an OracleAS Metadata Repository, but you can configure your 10g Release 3 (10.1.3) installations to take advantage of an existing 10g Release 2 (10.1.2) OracleAS Identity Management installation.

Table 6-1 provides an overview of Oracle Application Server 10g Release 3 (10.1.3) compatibility with previous Oracle Application Server releases.
