Stopping a proxy server ends a server
process based on the process
definition settings in the current application server configuration.
Before you begin
Ensure that you understand how stopping
a particular server affects
your ability to handle work requests, especially if you need to maintain
a
highly available environment.
About this task
There are times you
need to stop a proxy server. For example, you
might want to upgrade the operating system, or you might want to change
a
configuration setting for the proxy server. You can use one of the
following
options to stop a proxy server.
Avoid trouble: The quiesce function
for the SIP proxy server
is not supported on the z/OS platform. To use a similar function on
z/OS,
see the information center article,
Pausing an application server
listener
to manually update a high availability application.

Procedure
- You can issue the stopServer command
from the command line to stop a single proxy server.
Do not use the CANCEL proxyserver_proc_name command
to stop a server. Every time you start a server, a new temp directory
is created from the servant process token, such as profile_root/default/temp/node_name/server_name.
When you perform
a graceful shutdown, which happens if you cancel rather than stop
the server,
these temp directories are typically removed.
However,
if you infrequently perform graceful shutdowns, then these temp directories
are not removed and the hierarchical file system (HFS) used for these temp directories
becomes full.
- You can use the administrative
console to stop a proxy server.
- From
the administrative console, click .
- Select the proxy server, and click Stop.
- Confirm that you want to stop the selected
proxy server.
- View the Status value
and any messages
or logs to see whether the proxy server stops.
Results
The specified proxy server stops
as soon as requests assigned to that
server finish processing. To verify that the proxy server is in the
stop state,
in the administrative console, click .
Note: If
the stopServer command is issued from the command line, then the server
delays
shutdown for a period of time until new inbound messages to route
are not
no longer being received. The quiesce feature notifies the load balancer
to
discontinue routing inbound messages by sending error responses to
the advisor
messages.
