ArcGIS Server Memory Calculator - Script

Get-ArcSOCMemory.ps1

Run this script on your ArcGIS Server machine to measure the actual memory usage of running ArcSOC.exe processes. The output includes working set and peak working set statistics, and suggests a value to use in the Advanced calculator.

Usage

.\Get-ArcSOCMemory.ps1

If execution policy blocks the script, run:

powershell -ExecutionPolicy Bypass -File .\Get-ArcSOCMemory.ps1

Script

Copy# Get-ArcSOCMemory.ps1
# Scans ArcSOC.exe, ArcGIS Server, and Java processes to report memory usage
# and suggest values for the Advanced calculator.
