[Server-devel] Possible Jabber Problem on Server

[Berkowitz Andrew (Project Connect)]

I'll try nodeps. Usually, with LINUX servers, I avoid usually specifying
nodeps because it is easy to break dependant packages. I've gone through
pain fixing them  afterwards. It is good to know that in this case, I
can.

I've never had any problems wiping out the database, uninstalling,  and
reinstalling.

Without nodeps, my process was:
	/etc/init.d/ejabberd stop
	killall epmd (in case of hostname or ip address change)
	rm -rf /var/lib/ejabberd
	rpm -e xs-config
	rpm -e xs-pkgs
	rpm -e ejabberd
	yum install ejabberd
	yum install xs-pkgs
	yum install xs-config
	Run the domain_config script
	Fix a few config files
	Start ejabberd

with nodeps, my process will be
	/etc/init.d/ejabberd stop
	killall epmd
	rm -rf /var/lib/ejabberd
	rpm -e --nodeps ejabberd
	yum install ejabberd
	Fix config files
	Start ejabberd

I just burned the 1.63 ISO onto a CD. I'll load it onto a server today.

Nothing but ejabberd needs to be uninstalled.   Use the --nodeps
to force this.

Just reinstalling the package doesn't rebuild the database.
You will have to manually clean out the database before reinstalling...

I have no experience with uninstalling xs-pkgs and xs-config.
I doubt it would reinstall cleanly...

We certainly expect to have a lot of server, and remote management
is one of the tasks that has to be handled.    This wasn't remote
management so much as a bug fix.   We have several issues with
ejabberd, and in the long term are seeking a replacement instead of
finding work-arounds.
