No new features in that field. Maybe what you see is mod_mam, which supports rooms now.

mod_muc can be configured to use mnesia or odbc. But the participant list is short-lived data, which is kept only in RAM, not in a persistent database. So no, not possible.

Maybe it helps the ejabberd command get_room_occupants, that you can call using shell, XMLRPC or REST queries.

Thank you for all of that.

Here is what I just found in my debugging, so this seems to be related to mySQL.

I am going to turn-off "_odbc" and retest & then re-enable "odbc" again shortly.

Thanks, Jason

One thing we lost was that users could come back online & their 8 messages would just pop in for them & they'd be right back on track with their coworkers.

I was under impression that you are talking about the history of conversation, not about unreceived messages.

Note that you haven't described your config options, the steps you performed, nor the expected results and what you see instead.

Well, there is (almost) no configuration for mod_offline. I thought I recalled that it depends on mod_private, but it is false memory, it does not, I even have checked the source to be sure. So, you enable it in ejabberd.cfg, and it should "just work".

E.g., my config here uses it, and is working.
While it is not _odbc, the _odbc version should work just the same way. The only trouble I can think of is there could be the required table missing...

This is not a good way to identify the versions. You imply that the answerer should go to CentOS and MySQL homes to find out their current state. Also, it doesn't help to others later when someone having a similar problem would like to know what versions are discussed here. Will it be easy to say which versions are referred here, in a year or two?

So, by the way, I am referring to mod_offline.

I appreciate the important clarification. And, yes, I do want to enable mod_archive next, but for today, I need to enable mod_offline.

I have searched but not found a step by step for mod_offline. I tried enabling it on my own & am not doing it right. I have run the daemon in debug mode to watch its output there but haven't stumbled on the correct debug output to know what is wrong. I would be most appreciative of any one who can send me a snippet of working configuration for mod_offline. Thank you so much.

Hi, you seem to misunderstand

mikekaganski — Thu, 10 May 2012 21:42:36 +0000

Hi,

you seem to misunderstand the mod_offline purpose. It is used only for storing those messages that arrive while a user is offline, for delayed delivery.

I beleive that it is XEP-0136 that you seek to setup; the mod_archive is used for this in ejabberd.
