Portal Server on the Linux Platform

Sun Java™ System Portal Server supports RedHat 3.0 Linux platform, however, please note the differences between the Solaris and Linux platforms.

Limitations Using Linux

Please note the following:

•Portal Server and Access Manager must reside on the same server.

•The sample Portal does not support the Linux platform.

•IBM and BEA web containers are not supported.

Configuration files, deployment, and Application Programming Interfaces are the same for Solaris and Linux.

Comparison of Solaris and Linux Path Names
