What other server products can iPS 3.0 SP4 work with? See additional text for more description.

In iPS 3.0 SP4 installation notes, it is mentioned that Portal Server should not be installed on a system with other server products or other CPU/momory intensive applications. Can you pls let me know what server products are they refering to? I planned to install iPS on a machine which has iPlanet Calender Server, an Apache web server and an Oracle 8 database. Thanks.

It is not recommended to run portal or ldap in the same box as oracle because generally the OS tuning parameters for the two are different. The rest of the applications should be okay.
