Oracle iPlanet Web Server 7.0.9 Installation and Migration Guide

64-bit Support

Web Server 7.0 provides the option of installing a 64-bit version of the Web Server on Solaris SPARC and Solaris AMD64. If the installer detects a 64-bit system, you have the option to install the 64-bit binaries. This option is available only for the following platforms:

Oracle Enterprise Linux 4 U8+
Oracle Enterprise Linux 5 U4+
Oracle Solaris 8, 9, and 10 on SPARC v9
Oracle Solaris 10 on AMD64
Red Hat Enterprise Linux 4 64–bit
Red Hat Enterprise Linux 5 64–bit
SuSE Enterprise Linux 10.2 64–bit
SuSE Enterprise Linux 11 64–bit

Also note the following considerations:

The 64-bit binaries are bundled with the 32-bit binaries, and both are installed if the 64-bit option is selected during installation. You cannot install just the 64-bit binaries.
If you choose to install the 64-bit binaries during installation, all internal binaries are placed in the install-dir/lib/architecture directory, for example, /opt/oracle/webserver7/lib/sparcv9.
To determine if your Solaris operating system is 32- or 64-bit, use the isainfo -v command.
Following installation, the Web Server runs in 32-bit mode by default. For information about actions that must be taken to run the Web Server in 64-bit mode, see Enabling 64–bit Support.
When the server is configured to run in 32-bit mode (the default), 32-bit NSAPI plug-ins will continue to work even if 64-bit runtime is installed. Existing 32-bit plug-ins, however, will need to be recompiled as 64-bit plug-ins to work with a 64-bit server. In some cases, code changes will also be necessary. For more information, see the Oracle iPlanet Web Server 7.0.9 NSAPI Developer’s Guide.
Pure Java code does not need to be recompiled for the 64-bit architecture. If the Java code uses native Java Native Interface (JNI) user code, only the JNI code needs to be compiled. No changes are required for any JAR files. For more information about migrating Java Web applications to the 64-bit architecture, see the Oracle iPlanet Web Server 7.0.9 Developer’s Guide to Java Web Applications.
The Administration Server is a 32-bit application, but manages both the 32- and 64-bit Web Server instances.

Note –
ASP 4.0.3 is supported in Web Server 7.0.
Web Server 64-bit Linux is a separate stand alone distribution and cannot exist with Web Server 7.0 32-bit Linux. Web Server 7.0 64-bit Linux requires 64-bit JDK 5.0 Update 12 or above. Both Administration Server and server instance only are in 64-bit server
