Hi,

I ran cainfo for a PV but did not get a result for host:

[schumann@smartcon1 ~]$ caget PD_MOD1:tstable
PD_MOD1:tstable                /tmp/table_data.15901.dat
[schumann@smartcon1 ~]$ cainfo PD_MOD1:tstable
PD_MOD1:tstable
    State:         connected
    Host:              Access:        read, write
    Data type:     DBR_STRING (native: DBF_STRING)
    Element count: 1
[schumann@smartcon1 ~]$

Since the caget is working there would it appears have to be a host of

some sort. Is there an explanation for the blank host field?

Attempts to find an explanation at the ANL web site were unsuccessful.

When this happened to us on our linux hosts, I found that I needed the

Name Service Cache Daemon (ncsd).

So, I have this daemon running on linux and all is well now.

This is normally needed if you have a slow naming service.

I can't remember when this problem started; I wish we did not depend on

this ncsd.

Thanks,
Ernest
