Re: Graceful Restart of IWS Apache instance

If you do not want downtime, then multiple servers is the way to go with
a load balancer that can detect when a server is down and not direct
requests to it.

I do not think there is something like is described for Apache for an
application server. Also, I am not sure if the restart functionality of
the HTTP server is similar to what is described.

Thanks for the response. The problem with doing an end and start means
there
will be down time. The purpose of a graceful restart is to prevent any
downtime.

On IBM's website for HTTP Server (non IBM i) the command to use is
apachectl -k graceful [1]. This is usable in regular Apache as well.

The only other alternative I can find is having multiple instances and
load
balancing between them so I can take one down while the other stays up.

Just to add. Not all of my HTTP Servers are using IWS some are just
regular
HTTP servers. I would like to find a solution for both though.

Quite frankly, I am not sure if RESTART option is good if HTTP server

is

associated with IWS server.

If you simply do an endtcpsvr *http httpsvr(myserer) and strtcpsvr

*http

httpsvr(myserver) I think that would be best.

I would like to perform a graceful restart of an IWS Apache instance.

I see the restart command STRTCPSVR SERVER(*HTTP) RESTART(*HTTP)
HTTPSVR(MYINSTANCE). As far as I can tell it is not actually a

graceful

restart but nothing in the documentation actually indicates one way or

the

other.

Can anybody confirm if this is how to do a graceful restart?

Thanks,
