that's correct. use "named-journalprint /path/to/zone/journal/file.jnl" to see it in human readable form.

Why it transform to binary form instead of human readble form? Install centos 6.5 with build in bind 9.8.4 doesn't encounter binary form in secondary server. Is it security feature for Bind 9.9.5. Can it preset when zone transfer to secondary, it become human readable form instead of binary form. Kindly advise.

Why does it matter?? it's more efficient for the server to maintain data it can understand, and you have a simple way to read it.
