If you just use the latest Master/Commit server checkpoint as input, then the edge will be assumed to be unfiltered - this script will still work. NOTE: This script will stop and restart the edge server while it is running - so it will be unavailable for periods while this script is running. This script also resets the offline_db directory for the edge server. .Parameter SDPInstance The specified instance to process .Parameter CkpFile The specified (master/commit server) checkpoint file to recover from (assumed to be gzipped). .Example recover-edge.ps1 Edge1 p4_1.ckp.filtered-edge.1234.gz Will recover for SDP instance Edge1. #> [CmdletBinding()] param ([string]$SDPInstance = $(throw "SDPInstance parameter is required."), [string]$CkpFile = $(throw "CKPFile parameter is required."))
