Opcom message "%NTP-E-INVRPCTYP, Invalid RPC type" every second.

Hello.

I just set NTP service on my cluster. It's running well. Time is synchronizing. But on the console i start receiving this messages.

HPA1:SYSTEM>

I'm not able to find any information about this message. Thanks for help.

I have not seen that message before, but my first action would be to check my setup

$ diff sys$sysroot:[tcpip$ntp]tcpip$ntp.conf SYS$SYSROOT:[TCPIP$NTP]TCPIP$NTP.TEMPLATE

You may still have an "example" server ip address left in there, when they should have been replaced by your own server list.

Are you also using DTSS?

# The following commands allow interoperation of NTP with another time service
# such as DTSS. If enabled (by removing #), NTP will not set the system clock.

# server 127.127.1.0 prefer
# fudge 127.127.1.0 stratum 0

# The following commands allow this node to act as a backup NTP server (or as
# the sole NTP server on an isolated network), using its own system clock as
# the reference source. If enabled (by removing #), this NTP server will
# become active only when all other normal synchronization sources are
# unavailable.

# server 127.127.1.0
# fudge 127.127.1.0 stratum 8

Hello,

DTSS is not running and in TCPIP$NTP.CONF is only this:

# please do not make any changes to this file

Any idea?

Have no idea and did a search on my whole system disk 7.3 for "rcp type" and found nothing.

Which version of tcp ?

Try following some of the procedures in the manuals

http://h71000.www7.hp.com/doc/732final/6526/6526pro_contents_003.html#toc_chapter_13

for setting debug levels for NTP. You can then look in SYS$SPECIFIC:[TCPIP$NTP]TCPIP$NTP_RUN.LOG for the output.

Try using ntpq to check your setting and connections with the time servers.

If all else fails, you will probably want to trace the incoming UDP packets on port 123. Maybe you have some other application trying to use the same port?
