6.2

Depending on the resources and circumstances at your site, however, it may be possible to raise the
configured limit while maintaining fast enough performance to take advantage of concurrency in proxy
data collection. Although raising the limit can increase the time required for a single data collection, this
might be outweighed by the ability to collect more information from more compute resources and
machines at one time.
If you do increase the configured per-agent limit, you might have to adjust the default execution timeout
intervals for the different types of data collection that use a proxy agent—inventory, performance, state,
and WMI. If the time required to execute one of these activities exceeds the configured timeout intervals,
the activity is canceled and restarted. To prevent cancellation of the activity, increase one or more of
these execution timeout intervals.
Adjust Concurrency Limits and Timeout Intervals
You can change the per-agent limits on concurrent provisioning, data collection activities, and the default
timeout intervals.
When typing a time value for these variables, use the format hh:mm:ss (hh=hours, mm=minutes, and
ss=seconds).
Prerequisites
Log in as an administrator to the server hosting the IaaS Manager Service. For distributed installations,
this is the server on which the Manager Service was installed.
Procedure
1 Open the ManagerService.exe.config file in an editor. The file is located in the
vRealize Automation server install directory, typically %SystemDrive%\Program Files
x86\VMware\vCAC\Server.
2 Locate the section called workflowTimeoutConfigurationSection.
3 Update the following variables, as required.
