- Options for these daemons are documented in their man pages, which you can
- read online or in Managing NCS Software (Order Number D-11895-E).
-
- You'll probably never need to use any options for llbd or rpcd.
-
- For glbd, you might sometimes need
-
- -create -first
- when you create your very first glbd
-
- -family
- to override the default protocol family for replication when you
- create your very first glbd
-
- -create -from
- when you create replicas of the glbd
-
- -change_family
- when you want to change the protocol family used by your glbds for
- replication
-
- but you'll probably never need
-
- -listen
- which restricts the families on which a glbd listens for lookup or
- registration requests (and has nothing to do with the family used
- for replication)

- I'm not sure what you mean by this question, but maybe the following
- will help.
-
- If you have old glbds running now and replicating via DDS, then there
- are two ways to make new glbds interoperate with the old ones:
-
- [A] To make all glbds replicate via IP, first use "-change_family"
- to change the replication family for all of your old glbds, then
- specify an IP hostname when you create a new glbd (e.g., start
- the new glbd with "-create -from ip:foo"). See Section 5.1.7
- of Managing NCS Software.
-
- [B] To make all glbds replicate via DDS, specify a DDS hostname
- when you create a new glbd (e.g., start the new glbd with
- "-create -from dds://foo").
-
- For most configurations, I'd recommend [A], which might make future
- additions of glbd replicas easier.
-
- After you've done either A or B, you won't need to use any options
- when you restart glbds, because they'll know what family to use.
-
- See Managing NCS Software for details.
