Documentation for configuring multiple object servers with single library server

[sandeepveldi]

Hi,
Can anyone please point me to any documentation corresponding to configuring CMOD with multiple object servers & single library server?

Thanks & Regards,
Sandeep Veldi

Hello Sandeep,

Well normally when you do that, you need to use to configure the ars.cfg in each node according to its role.

The library server will have the parameter ARS_SRVR set to nothing
and each object server will have this parameter set to the library server
http://publib.boulder.ibm.com/infocenter/cmod/v8r4m1/topic/com.ibm.ondemand.installingmp.doc/ars1i071109.htm#wq132

Then each object server needs to have the following daemon running arsobjd instead of arssockd. http://publib.boulder.ibm.com/infocenter/cmod/v8r4m1/topic/com.ibm.ondemand.installingmp.doc/ars1i071563.htm#startobjdlin
And of course you can create on each object server the corresponding ars.cache for the cache.
the ars.ini will be the same on each server http://publib.boulder.ibm.com/infocenter/cmod/v8r4m1/topic/com.ibm.ondemand.installingmp.doc/ars1i07176.htm#wq101, only the ars.cache and ars.cfg will differ. ars.dbfs will be used only in the library server.

The problem the info on how to do it in every chapter and sub-chapter of the CMOD manual... so I could send you at least 10 or 20 links there and there... I have no single point of reference!

I hope this is a good enough starting point.

Cheers,
Alessandro

Alessandro,
Thanks for your response
So, can we configure multiple object servers on the same work station? Are there any special installation instructions that have to be followed for object servers?

Just in case someone steps here. This is the link to a tech note on this topic.

Can I have multiple OnDemand object servers on the same physical workstation?
Technote (FAQ)


Question
I have a single IBM? Content Manager OnDemand library and object server running on the same physical workstation. I would like to set up another object server on the same workstation for testing purposes.

When configuring a new object server, I can specify the IP address and port, but when adding storage nodes to my storage set using the OnDemand administrator client, I cannot set the port.

Is it possible to setup another object server for the same OnDemand Instance on the same physical workstation?

Cause
There are no options to specify the port of the object server when adding a storage node in your storage set because of security reasons. The object server is expected to run on the same port as the library server. This restriction is why you are not given the option to specify the port.

Answer
You can have multiple object servers on the same physical workstation, but they must be associated to different OnDemand library server instances that are running on different ports. However, this setup defeats the purpose of creating a dedicated object server because it increases the workload for that workstation.
