Hi,
You shouls post this in Automic Workload Automation forum instead.
Just a few comment :
1 - Do you have any restrictions in the queue used to run the Call-API commands ? See UC_CLIENT_SETTINGS parameter.
2 - Do you have any restriction in the parallel run of the object you want to activate ? See object definition "Task running in parallel" parameter.
3 - Do you have any restriction in the number of connection allowed simulteanously in the Client ? See UC_CLIENT_SETTINGS parameter. Each use of the Call-A
PI is using one connection to the Client. So if you have allowed 5 connection to the client and you have 3 GUI active, you cannot run more than 2 Call-API at the same time.
This may impact the possibility to activate multiple times the same object at the same time.
Regards.
Alain
