You need to search for OWNER_NAME.

cat -v dumpfile.dmp | grep -o '.*' | uniq -u

cat -v turn the dumpfile into visible text.

grep -o shows only the match so we don't see really long lines

uniq -u removes duplicate lines so you see less output.

This works pretty well, even on large dump files, and could be tweaked for usage in a script.
