rpc errors

Francois Bariselle_3 — Tue, 11 Dec 2001 16:43:29 GMT

I have a general utility program for manipulation of TRIBON objects located on
data banks (Informix data banks). The program performs activities like listing, copying etc. of objects in and between data banks.
The program return this error:

Could Not connect to TRIBON DB SuperServer on Host
Host unknown
xd210_rpc : could not create client handle
: RPC_UNKNOWNHOST
Could Not connect to TRIBON DB SuperServer on Host
Host unknown
xd213_rpc : could not create client handle
: RPC_UNKNOWNHOST

My Database Server run on my node equipped with physical disk devices where the database files are stored. I say that is not possible for the Database Server to access database files located at other nodes through NFS.

Help me please !!!

hey,

Check whether the rpc daemon is running or not?

Check the output of 'rpcinfo -p' and see whether the application is assigned with any port ?

HTH,

hi,

try this:
ps -ef | grep rpc
and you must obtain:

hi,

Perhaps this help you:
man rpcd
man rpc.statd
man rpc.lockd

hey,

does your application assigned with a port number?like 'ypbind' is running on the port no-100007.

If not, then you can restart the rpc services of your application.

hey,

In the output of 'rpcinfo -p' you have to look for your application's daemon. For eg: from the output, I can understand that the NIS daemon 'ypbind' is working in your system and looking rpc requests.

Try this: if your application daemon name is "appld" then,
rpcinfo -p | grep appld

If it not find running, try restarting the service/application.

My database server is on port 4663, program 300315 and version 16.
Look the result of :

rpcinfo: RPC_TIMED_OUT
program 300315 version 16 is not available

Sirius is my node name

Re: rpc errors

Helen French — Tue, 11 Dec 2001 19:27:54 GMT

hey,

did you tried restarting the application?

Shiju

Re: rpc errors

Francois Bariselle_3 — Tue, 11 Dec 2001 19:38:26 GMT

yes I tried restarting my application.

All the time, when I use rpc info -n -u with a program that use tcp protocol i have this message:

rpcinfo: RPC_TIMED_OUT

Is it normal ?

Re: rpc errors

Helen French — Tue, 11 Dec 2001 19:46:05 GMT

No. It is not normal. Look this and see whether it helps u:

Re: rpc errors

Francois Bariselle_3 — Tue, 11 Dec 2001 20:25:36 GMT

The portmap program is already running on my HP system before running my application!
It's not the good solution...

I tryed and it's good.
-t for tcp protocol and -u for udp protocol.

So, the result of on my server seems correct!

The process rpcbind do not work on my server. Is it normal ?
