# ============================================================================ # Copyright and license info is available in the LICENSE file included with # the Server Deployment Package (SDP), and also available online: # https://swarm.workshop.perforce.com/projects/perforce-software-sdp/view/main/LICENSE # ---------------------------------------------------------------------------- <# .Synopsis Recovers an edge server from specified Master checkpoint (which may be filtered) Particularly intended for use with filtered edge servers, but handles an unfiltered edge server too. .Description Recover the edge server from the latest commit server checkpoint, while keeping any local edge server specific state such as db.have/db.working etc. The normal expectation is that you will use a checkpoint created by the script create-filtered-edge-checkpoint.ps1 If you want the edge server to be filtered, then you MUST use that script. 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."))
