RPC program registering

[Helena Stritch]

Hi,
I have installed the TIBCO staffware application. When it starts up it needs to register a port with rpc, but it fails with the following errors:

T004: RESTART: WQS RPC number = 1073741824
T004: RESTART: LI RPC number = 1073741824
T004: Using RPC version 11
R004: rpcport_alloc (mode= 0, ptype = 2, pid = 119)
T004: sw_register_rpcport_server non-TI_RPC (rpc=391875, port=0, tcp, ver=11)
T001: check_rpc_prog (tcp) : Failed to register program 391875 version 11
T001: check_rpc_prog (tcp) : clnt_create() failed for program 391875 version 11
T001: check_rpc_prog (tcp) : 'sw_register_rpcpport_server: RPC: Program not registered
T004: check_rpc_prog () : pmap_unset () for program 391875 version 11 failed
T001: register_rpcport (pid=119, prog=391875) - unable to register tcp
T001: Registering RPC Listener Server Failed (RPCnum/port= 391875/0)


How could I test that RPC is running OK on the server (without restarting it! - It's a shared production server)

rpcbind daemon is running.

Thanks in advance,
Helena

There are several kinds of RPC in existence. Furthermore, RPC is not a process but a way for the processes to "talk" to each other, so it's a bit of a misnomer to say that "RPC is running". You can certainly check that the central component of the RPC server is running, but that doesn't tell you everything you need.

There is "Sun RPC" which is used in NFS, NIS and some other services. A key part of it is the rpcbind process (also known as "portmapper" on some unix flavours). To test this one, you could run "rpcinfo -p" - it should list all the active SunRPC services on the current host.

Then there is "DCE RPC" which is entirely different thing. On HP-UX, there is a process called "rpcd" (/opt/dce/sbin/rpcd) to handle this one. One way to test this one is to run this command:
rpccp show mapping ncacn_ip_tcp:127.0.0.1
If all's well, it should display several groups of four lines (object, interface id, string binding and annotation).

To start the rpcd component of DCE RPC on HP-UX, the command is (note the capital R):
sh /sbin/init.d/Rpcd start

The messages from your application look like it's probably trying to use SunRPC, but I'm not completely certain.
Check /var/adm/inetd.sec to see if there are any access restrictions defined: they apply to (some) SunRPC services too.
