Replication Server 15.2 with non-blocking commit enabled supports replication into Oracle 10g v2 and later because Oracle 10g v2 supports functionality similar to delayed commit.
Replication Server 15.2 heterogeneous datatype support (HDS) scripts have new function strings that support the non-blocking commit feature. Sybase Enterprise Connect Data Access for Oracle supports these function strings. See the Replication Server Heterogeneous Replication Guide.
