Hi Eygene,
Thank you for your reply.
As I know, there is a rgma-gin daemon in ce/se as a rgma client. Which
is the relationship between rgma and apel?
In siteinfo.def file, I also find a line about apel password, should I
define the password of mysql server in rgma server?
I am still not clear though I have looked into the material in rgma website.
Best Regards,
