4 32 and 64 bit here refers to the supported OS. Sun Java System Application Server is a 32 bit application.
On UNIX, you can check your operating system version using the uname command. Disk space can be checked using the df command.
On Solaris, ensure that the system-wide instance of perl under /usr/bin/perl is in the path. Application Server installation will fail if the default perl installation is not found.
HADB is not supported on Microsoft Windows or Red Hat Enterprise Linux operating system versions in 64 bit mode. On Solaris (x86), HADB has been tested only in 32 bit mode of the operating system.
HADB uses Intimate Shared Memory (SHM_SHARE_MMU flag) when it creates and attaches to its shared memory segments. The use of this flag essentially locks the shared memory segments into physical memory and prevents them from being paged out. Therefore, HADB database’s shared memory is locked into physical memory, which can easily impact installations on low end machines. Ensure you have the recommended amount of memory when co-locating Application Server and HADB.
