1929.0. "ni_status_awk is not running when disconnecting standby network cable" by NETRIX::"[email protected]" (Ravid Shimon) Sun Mar 09 1997 01:44

Shalom

Running ASE version 1.4 on dec 3000 with 4.0B unix OS.

when i disconnect the network cable from the standby machine,
the script ni_status_awk on the master machine is not running.

Note that there is just one network between the systems, and 
the interfaces defined as monitored.

Any idea will be appreciated.

Regards,

Ravid Shimon

1929.1are you sure ?BRSDVP::DEVOSManu Devos DEC/SI Brussels 856-7539Sun Mar 09 1997 13:0213
    Hi Ravid,
    
    Did you wait enough time before concluding it is not working?
    
    The ASE Admin guide is explaining there is various delays and retries
    between successfull and unsuccessfull queries on the monitored
    interfaces (as well as on pings and scsi pings).I think that the delay
    between the queries on the Monitored interfaces is 30 seconds. This can
    be changed by creating a file /etc/hsm.conf as described in the Admin
    guide. 
    
    Regards, Manu.

    If you have only 1 net then that net is also the primary ping
    net... It sounds to me like you should be observing a net
    partition - 
1929.3yes, i'm sure ?NETRIX::&quot;[email protected]&quot;Ravid ShimonTue Mar 11 1997 02:1012
Hi,

I have been waiting for more than 6 minutes after disconnecting the cable.

Maybe the second reply is the solution for it.

Thank you both.

    I'm at a site now that also has only a single network. What
    I observed when I pulled the net cable out of the standby system
    was that 'nothing' happened... ASE noted that the standby system
    went away but it took no action... which is appropriate, I
    guess.
    
    WHen I pulled the cable out of the primary system (we're talking
    FDDI) after some delay ASE decided to shutdown the service (I
    assumed in an attempt to failover to the standby box)..
    Unfortunately, for some reason oracle (which we run as part of the
    service) fails to shut down, which leads to our stop script
    getting timed out after a while... which then leads to a failed
    attempt to deport the disk group and offline the disks... which
    leads to a reboot of the primary system... which leads to the
    service coming up on the failover system - eventually.
    
    There's always a lot of details involved in whatever happens
    with these systems... not alway pretty.

    Hi Dave,
    
    Did you modify the dbshut script of oracle to do a "shutdown immediate"
