On 64-bit HP-UX systems, if you expect to have data stores that are
larger than 2GB, you must enable large files. By default, HP-UX

To enable large files, create the filesystems using
option. Use the command:
% /usr/sbin/fsadm -F hfs -o largefiles device_name
% /usr/sbin/fsadm -F hfs -o largefiles \
For replication, TCP send and receive buffers should be increased to a
minimum of 512KB. You may need to embed the following commands
into a script that can be run at system boot time:
