ld: fatal: file /dev/zero: mmap anon failed

If you get the following error while installing Oracle database server software on SUN
Solaris, chances are you're out of swap space or there is not enough RAM:

ld: fatal: file /dev/zero: mmap anon failed

Use these utilities to check the swap space:

swap -s
df -k /tmp

Either get your Unix administrator to add more swap or do something like reducing the SGA for
other databases running on the server.
