Why do they want independent servers sharing the same database? I don't think the system is designed to work that way. I'm thinking that they don't really understand what a server group is. What's the rationale behind the approach they're asking for?

In ITSM 7.0.03, which is all I've read up on recently, you'd install all the CMDB/ITSM components on server A, and then copy the newly added files/folders from server A's filesystem to the same places on server B's filesystem. Then you manually update server B's ar.conf (or ar.cfg) adding the references to the copied files (usually plugins) to match server A's config file. At least this is what I've gathered from the ITSM installation docs - anyone please correct me if I'm wrong. As for patches, I've frequently seen sections in patch docs that talk about installing in a server group, so I'd suggest just handling patches per the readme files. BTW, it turns out this was a moot point for me, as the customer wants not a server group, but two independent servers with a shared database. That build goes something like this: 1. Install ARS, ARS add-ons, CMDB, & ITSM on server A against the production database 2. Install ARS, ARS add-ons, CMDB, & ITSM on server B against a scratch database 3. Edit server B's ar.conf to point to the production database, and optionally delete the scratch database 4. Manually make sure that admin functions, escalations, reconciliation engine, etc only execute on one server (and hope that no one messes up in the future) Fun, eh? --Phil From: Action Request System discussion list(ARSList) [mailto:arsl...@arslist.org] On Behalf Of Jason Miller Sent: Friday, August 20, 2010 16:06 To: arslist@ARSLIST.ORG Subject: Re: ARS 7.1 and ITSM 7.0.03 Server Group Build ** Not to steal your thread Phil... You tapped into something I have also been wondering about regarding setting up server groups with ITSM 7.6. Our new 7.6 environment will be our first time using server groups too. Lyle described ARS components. Beyond the base ARS, does this work the same to lay down the Atrium, SLM, ITSM binaries/services? Install on A, start the server group on A then install everything on B as a member of the server group? It is my understanding that it works this way, I want to do a reality check. <background> We will have one app server for automation (AIE, reconciliation, normalization, Escalations, Email, etc) and admin tasks and one for user traffic. I originally tried building both servers at the same time as a group. This was the same time I was having an issue installing fresh with ARS 7.5 patch 3&4 (thread "ARS 7.5 Patches for a new install" from March). In the interest of time I restarted fresh and only built one server. We are now in production but the user traffic is very light so I haven't worried about it yet. I am hoping to hold out for the Server Group session @ WWRUG10 that Phil Bautista teased us with. </background> All we need to do is configure server A for a server group and install everything on server B as server group member? Can somebody validate that this is the correct approach for the full suite? What about patches? We are on patch 5 ARS, patch 1 for ITSM and patch 2 for Atrium Core. Obviously we don't need the db definition updates but we do need the binaries on server B. The patches are inclusive but there has been discussions regarding starting from the base install and patching up. Does anybody know if the you can really bring a server into a server group by just using the patch installers? Thanks for any input.

That is, tell server A it is a member of a server group, and then install B, telling it to share the database. You can install everything on A whenever you want. I would probably install everything on B once B knows that it's a member of the server group. My preference is to install EE, FB, etc on each of the server group hosts (or on some other host, but I have a dedicated instance of EE, FB, etc. for each member of the server group) and point each to the local host (or to its dedicated server) rather than to the server group (an alias, etc.). That way, you're more guaranteed to get proper failover if there is a problem with one of the hosts or something.
