mq series and service guard problem

[Juergen Feldmann]

Hello,
we have running a mc serviceguard package with mq. During package shutdown /var/mqm could not be unmountet and fuser -ku also doesn't
helps. All processes are killed an no shared memory segments and semaphores are available, but /var/mqm is allways busy.
What's wrong here? Are there any open files that we could not see?
MQ is running on hpux 11.11.

Thanks
Wolfgang

Hi,

mabe you have mq listener in /etc/inetd.conf file ?

I meen:

QM_1 stream tcp nowait mqm /opt/mqm/bin/amqcrsta amqcrsta -m QM_1

if yes this is couse of busy /var/mqm.

Hi,

Ensure that all the application processes are *completely* down before bringing down MQ. When it fails again, find out the processes that are accessing the /var/mqm filesystem by running "lsof". Then you can be able to adjust your scripts to clean those processes before serviceguard attempts to bring MQ down. ALso ensure to take out cronjobs for MQ if any otherwise they can make /var/mqm busy even after the application shutdown.
