Trying to understand multiple instances of base server

There are server instances. Can each of these server instances have more than one "deploymentConfiguration" files ?

At the time of deployment, I can select any server instance and then select any deploymentConfiguration file to run that deployment ?

Does each server instance have only one odbase.xml or odbase.rcvr ?If yes, then if deploymentConfiguration files have to have same receivers ? So only thing we can change is the source right ?

I mean, say there are three receivers specified in odbase.xml and odnodes.xml. So in deploymentConfiguration file, only these three receivers can be used. Nothing less , nothing more. Correct ? But I can change the number of directories. So if abc_deploymentConfiguration.xml
has got 5 directories being deployed to 3 receivers. Then xyz_deploymentConfiguration.xml for the same server instance will be deploying to the same receivers only. But it can have different directories, right ? So in this case, there can be only one odbase.xml and odnodes.xml for each server instance. Right ?

Pls correct, if my understanding is wrong

Thanks

First of, are you sure you need named OD Instances? Why? Do you have licenses for them? Although by no mean rocket science
it's an advanced configuration that requires additional resources to maintain and administer. Single anonymous Instance
(default Install) is perfectly adequate in perhaps 99% of OD Use Cases. That said...

Please note that named OD Server Instance *owns* certain instance-related od-home subfolders. Naming convention is
od-home/(od instance name)/(folder name). For example, if you install an Instance "khyati" you will have (among other)
Folders "od-home/khyati/etc" and "od-home/khyati/conf". Default anonymous Instance has it like "od-home/etc" and
"od-home/conf".

Q. Can each [...] server instances have more than one "deploymentConfiguration" files?
A. Yes. You can create arbitrary Folder Structure under "od-home/khyati/conf" with any number of Deployment Configuraion Files within.
OD CLT Configuration reference is relative to the corresponding conf, like this:

iwodcmd -odinst khyati start intranet/intranet_conf0 -inst 31415

It implies that there is a Deployment Configuration File "od-home/khyati/conf/intranet/intranet_conf0.xml".
Note that XML Extension is dropped and that you can not shuffle around -odinst Flag. If present it must immediately follow 'iwodcmd' literal.

Q. At the time of deployment, I can select any server instance and then select any deploymentConfiguration file to run that deployment?
A. See above. You can select any Instance and any Configuration *owned* by this Instance.

Q. Does each server instance have only one odbase.xml or odrcvr.xml?
A. Yes, each Instance has only one. Note though that etc subdirectory is instance - specific. Although it's only one
base/rcvr per Instance, it IS NOT THE SAME FILE for all instances. It is up to you of course to populate these Files
identically - or not.

I hope that's enough to answer the rest of your questions yourself.

Thanks Boris.

I am beginnier with OpenDeploy and thats why I have these basic questions.

Most of the times, we are using just default instance. Then if we need to deploy to different server sets using different deploymentconfiguration files, how can we do that ? As there is only one odbase.xml and odnodes.xml for one server, only one set of receiver servers can be configured. This is one point confusing me.

Does it cost to create new server instances ? Does it require separate licencing ?

Thanks

Read OpenDeploy® Administration Guide. Take some training.

Basically, you deploy to the so called "replicationFarm"(s). Those are named entities that reference Nodes. You can declare them
in odnodes and/or in Deployment Configuration itself. Different Deployment Configurations may therefore deploy to totally different
"Farms". There are explanations and samples in OD Manuals and DevNet.

You would have to talk to your IWOV TAM regarding cost and licensing

I did go through deploymentConfiguration files and I know about replicationFarm field. I know, I can specify different server sets in replicationFarm field. As we can have more than one deploymentConfiguration files, I dont have problem with that.

My confusion is about odnodes.xml and odbase.xml. I can have only one of these files on a server. Now, if I have specified 3 receiver servers in odnodes.xma and odbase.xml, I can deploy to these three servers only, right ? So the deploymentConfiguration file with these three servers is not a problem. But what about the deploymentConfiguration file in whose replicationFarm field, there are 4 receiver servers and one of which is not specified in odbase.xml and odnodes.xml , how will the deployment work in this case ?

Or is it like that we specify all the receiver servers in odnodes.xml and odbase.xml. Then out of these servers, I can choose to specify the servers in deploymentConfiguration file. Which means that odbase.xml and odnodes.xml has the list of all the possible receiver servers, while deploymentConfiguration file can have all or some of these servers in its configuration. In this case whatever deployment servers are specified, since all of them are in odbase.xml and odnodes.xml, there wont be a conflict. But if a specific server is not there in replicationFarm field, then eventhough its in odbase.xml and odnodes.xml, still deployment to this specific server will not take place because of not being mentioned in deploymentConfiguration file.

Is my understanding correct ?

It won't. It is that simple. As stated by IWOV, "A deployment configuration has dependencies on a set of machines (nodes) defined in IWODHOME/etc/odnodes.xml".

In general - the odbase.xml does not list all the receivers - that is the job of the odnodes.xml.

The odrcvr.xml (on the receiver) lists all of the senders that it is willing to accept deployments from, and the root directories under which it will allow those senders to deploy content.

The odnodes.xml file must define all possible target servers (receivers and/or other base servers) to which the current base server may deploy.

The replicationFarmSets can be defined directly within the deployment configuration file - or within the odnodes.xml file (my preference) - and each replicationFarmSet contains references to a subset of the nodes defined in the odnodes.xml file (the subset can be anywhere from one node to all the defined nodes)

As has been stated - if you haven't read the manuals - do so. If you have read the manuals and don't understand these concepts - take training. You can ask these questions here - but if you need that level of help the training is generally worth it.

I think the confusing thing here is how instances actually work. When you "declare" an instance it will setup all of it's own configuration files (odnodes, odbase, etc) and you would configure it just like you installed a separate instance. There are of course some shared files between instances, but I think in terms of this discussion, this should clear up the concerns.
