Restarting TCPIP in OpenVMS without reboot

Jasper_15 — Wed, 09 Nov 2005 19:27:40 GMT

Greetings,
Is there a way to restart TCP/IP in OpenVMS 7.3-2 without rebooting the server? I expect something wrong with my export share-point and it refused connection from my Linux server.

Please help!

Thank you in advance.

Jasper

Hi Jasper,

$ @sys$startup:TCPIP$SHUTDOWN.COM

$ @sys$startup:TCPIP$STARTUP.COM

If some of the clients are still holding on to the BG devices, you may not have a clean shutdown.

Thanks and regards.

For NFS you can use

(server)
$ @SYS$STARTUP:TCPIP$NFS_SHUTDOWN.COM
$ @SYS$STARTUP:TCPIP$NFS_STARTUP.COM

(or client)
$ @SYS$STARTUP:TCPIP$NFS_CLIENT_SHUTDOWN.COM
$ @SYS$STARTUP:TCPIP$NFS_CLIENT_STARTUP.COM

without impacting other connections.

Jasper,

Menu based
$ @sys$manager:tcpip$config.com

--> choose option 6 to start TCPIP
--> choose option 5 to stop TCPIP

Manual
$ @SYS$STARTUP:TCPIP$STARTUP
$ @SYS$STARTUP:TCPIP$SHUTDOWN

Hi,

don't forget to log to SYSTEM account for @SYS$STARTUP:TCPIP$STARTUP or submit it with /USER=SYSTEM. And of course, you'll need enough process privileges for shutdown from different account then SYSTEM.

A few things to remember if you should restart TCPIP as a whole:
1. DON'T DO THIS IN A TELNET SESSION. Shutdown would not be a problem but it will drop your connection - and you will not be able to restart it unless you have another way of connecting (DECNet, or console).
Of course you can prevent this when running the stop/start sequence in batch. But if startup fails, you still need that other (non-TCPIP) access method to find out why it didn't.
2. Be sure that other TCPIP-based programs such as webservers are stopped BEFORE you restart TCPIP. TCPIP$SHUTDOWN will warn you if this is the case. These programs may continue to run but will need a restart as well after you restarted TCPIP.

If you just have to start and stop NFS services, beware of open sessions. All connections may need to be restarted.

enable network opcom messages and try the connection and you may see a message from the NFS server about why it refused connection from your linix server.

Have a look in OPERATOR.LOG for older messages.

If you are trying to reboot your system, it works fine (even SET HOST xxx will work). It doesn't mather or you are logged in over TCPIP or DECnet ! This was an issue in the (very) early days.

If you only stop TCPIP and want to start it up, yes, this can not be done when you are logged in using a IP connection.
The easy way to do this is make a com-procedure including
$ @sys$startup:tcpip$shutdown
$ @sys$startup:tcpip$startup
and submit this as system. This works fine, I'm doing this sometimes when a particular part of IP restarting wont work.

@Anton: Of course: Reboot can be initiated from a telnet session, as well as TCPIP$SHUTDOWN. But if, for some reason, TCPIP is not started during reboot, you're done. You need another route into your system te start TCPIP. Console (obviously) or, indeed, DECnet (unless you do DECNet over Ip, since that requires TCPIP - which has not started)

But reboot wasn't the point here. Jasper wanted to restart TCPIP without reboot. And than the warning holds :D

@jasper: First you should determine the cause of trouble, if you think the problem is within the system. After reboot NFS might work again - but your running environment will be lost - finding clues on what went wrong will be somewhat troublesome :D

If you have Telnet-symbiont printqueue's, check them after full TCPIP stop/start; sometimes the queue's can go into 'stopped' state.

Hello - I did what Andy had suggested and now my NFS mount-point is once again working.

(server)
$ @SYS$STARTUP:TCPIP$NFS_SHUTDOWN.COM
$ @SYS$STARTUP:TCPIP$NFS_STARTUP.COM

Thanks everyone!!
