(1) In ArcGIS Server 10, there used to be utility (EXE) to add server instance, but I do not see the this in 10.1 . How to add another ArcGIS server instance ?
(2) How to decide Minimum number of instances per machine and Maximum number instances per machine to configure a service in ArcGIS server 10.1 ?
(3) With Isolation setting LOW, How to decide Instance per processes from 8 (default) to maximum of 256 in ArcGIS server 10.1 ?
Please help me on above issues.
