For advanced hub configuration, the only parameters that you might want to modify are related to the change log. As a supplier, a hub server requires a change log.
You can use DSCC to perform this task. For information, see Directory Service Control Center Interface and the DSCC online help.
To modify a change log setting on a hub, use one of the following commands:
$ dsconf set-server-prop -h host -p port suffix-DN repl-cl-max-age:value |
$ dsconf set-server-prop -h host -p port suffix-DN repl-cl-max-entry-count:value |
