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
