Hmmm,
     No relies at all.

I checked sunsolve again, and finally found patch 105401-25
we had 105401-20 installed.

Problem Description:

4165775 Replica servers may attempt to allocate huge amounts of memory

4216240 nisd patch 105401-20 generates irrelevant messages "isn't a directory"

(from 105401-23)

4186012 NIS+ replicas may loose synchronization with the NIS+ master

4162879 After the TTL value of directory cache expires the subdomain client. root object

(from 105401-19) --

Installing the uprev fixed the memory problem, and reduced our error logs considerably.

Still no suggestions about the NIS reorg'. We will have to set up a test domain and test a few ideas.

Hello Sun Managers we wish to reorganise our NIS+ structure. At present we have a top domain and and two subdomains, eg

top / \ / \ sub1 sub2

we are considering changing the name of the masters of the two sub domains. At present the masters are both home directory file servers AND NIS+ masters. This makes replicas useless, since if the master fails there are no home dirs anyway.

I'm aware that it is quite involved to change the name of the root master, but what about the domain masters?

We are running 2.6(Generic_105181-15)

In addition we are finding that one of our replicas is grinding to a halt. rpc.nisd grows to > than 1000MB in a top listing and keyserv appears to die;

we get a lot of

nisd[613]: check_updaters: Unable to fork readonly process.

in the logs

a "showrev -p | cut -d" " -f1,2 | sort"

says that we have the following patches( I have deleted uprevs)

<snip>

Your opinions or help would be appreciated. -------------------------------------------------------------------------
