How does Efficy application choose what Oracle client should be used? (10.2 , 11.2 ?)

Hello,

In the scope of migration from Efficy 10.2 to 11.2 I am facing some challanges with the Oracle client upgrade 32bit -> 64bit

Problem : At the client we have 20+ production servers and they have to be updated in rather short time. In case of unforeseen issues with the upgrade the impact on downtime of Efficy PRD is big.

To diminish this impact we thought about the following solution :
- Install 64 bit version server by server before the migration day
- inside the PATH variable specify 32 bit version and not 64
- during the migration day switch PATH from 32 to 64

Questions :
Do you see any flows in the foreseen solution ?
How does exactly Efficy choose what oracle client should be used ?
Is it possible to specify explicitly to Efficy application, what version should be used ?

Thank you in advance,
Best regards,
Vladimir
