Oracle and SQLServer on the same box?

Develop on both Oracle 9i and SQLServer 2000 back ends and would like to set up a new test/development server. Are there any issues with running both systems on one box?I install Oracle 8i personal edition and SQL server 2000 on the same machine without any problem|||... and I installed
1) Sybase ASE
2) Sybase ASIQ
3) MS-SQL 2000
4) Oracle 9.02
5) IBM/UDB 7.2

2. Oracle 9i
3. MySQL
