[Koha] how to use OAI-PMH

[vijay kumar]

Dear all,
I want to use OAI-PMH for metadata harvesting.
I checked manual for OAI-PMH but didn't get more idea regarding the
use and configuration of OAI-PMH

I am using koha-3 and my  z3950 searching is not working....
And I donot have idea regarding how to configure OAI-PMH and Z3950

Anyone please suggest me regarding this.
Thank you in advance,

with regards,
vijay kumar
