Strings does not work for big file

I was trying to calculate DBID of oracle database according to the topic Oracle in World: How to Discover find DBID and following number 2) mechanism specified there that is using of strings keyword.

My unfortunately my oracle database datafile is so big that I could not use strings keyword for searching.

I used,
strings datafilename_loc.

It failed with big file size. What I will do now?
How I can open file with strings?

A few options come to mind. First, split the file up in to smaller pieces
with ‘split’.

Another option, read in a small amount of the file and pipe it through
strings. For one megabyte, for example:

dd if=/path/to/your/file.ext bs=1024 count=1024 | strings | less

Good luck.
