Concurrent Managers on Multiple nodes

Question

Hi,
We have this setup
2 DB server - RAC & ASM
2 APPS server - which has loand balancing through IP configuration.
Now we have requirement of having concurrent managers in the DB server. I am bit confused here
1) suppose if i install cm tier on both DB servers and ask them to communicate to RAC DB server, IF any request comes , how this will distribute the work between two servers.
2) do we have to configure anything ?
3) Is there any entry is available in config files with respect to CONCURRENT HOST NAME. How the values are populating in FND_NODES table.
4) am i thinking two complex, is there any other solution to achiev this - Basically i have to have concurrent manager in both DB server and work needs to be shared automatically.
Waiting for your valuable inputs.
Cheers!
Venki.

Answer 1

Forgive my brief answers; I'm headed to bed and don't have time to dig up full references. :-)
As a side note, in the future, please start a separate thread. Your environment and requirements are different from the original poster, and replies may be confusing, both to future readers, and to those trying to help.
1) Is it possible to configure PCP keeping both the CM on appsTier in non-RAC env. ?Yes.
2) If yes, will both the CM work at the same time or one at a time? In other words, it can distribute the CM load among the CM tiers?All the CMs will run at the same time, managed by ICM and GSM.
3) If yes, please provide me a guideline or any special instruction.You note below that you won't be using a shared application tier filesystem. You might want to reconsider this architecture. At the very least, you will want to share the log and output directories for the concurrent managers. Life will be much easier if all nodes can see the same log and output files. :)
Take a look at section 3.12 of
Note 388577.1: Using Oracle 10g Release 2 Real Application Clusters and Automatic Storage Management with Oracle E-Business Suite Release 12. Although you're not running RAC, this section of the document explains the various parameters needed to configure PCP.
Also, if you haven't already, review the sections on PCP in the Oracle E-Business Suite System Administrator's Guide - Configuration
Since, I'm planning to go with 2 appsTier nodes (non-shared, local filesystem), I would like to go for LoadBalancing configuration as well.
Refered Note: 380489.1 - Using Load-Balancers with Oracle E-Business Suite Release 12
Section 2.4 Using Domain Name Server (DNS) Load Balancing with Single Web Entry Point
Is the above DNS Load Balancing is only for web services? what about other services (forms,CM)? Should work for Forms as well. CMs mostly care about where the database is, not the web/forms entry point, so the Load Balancer doesn't come into play for the CMs ...at least, I'm pretty sure that's true. It's late. :)
Once LoadBalancing is done, then is it possible to go for E-Biz integration with OID/SSO?Yes. See Integrating Oracle E-Business Suite Release 12 with 10g AS Oracle Internet Directory and Oracle Single Sign-On
