                            Release Notes for
                 SDP - Helix Server Deployment Package
                        Helix Server Components

Introduction

   This document notes changes to the SDP.  There are two flavors of the
   SDP, Unix and Windows.

   At a high level, the core function of the SDP is similar on
   Unix and Windows:  To maintain an offline copy of the Helix
   databases, and perform routine offline checkpoints in preparation
   for backups.  At a detailed level, there are differences in both
   implementation and behavior on the various platforms.

   Enhancements are needs-driven, and not necessarily applied across
   Unix and Windows platforms.

--------------------------------------------------------------------------
Upgrading the SDP on Unix

   To incorporate a new version of the SDP into an existing
   SDP installation, first stage the deployment as in this
   example, assuming you have put the SDP distribution tar file
   in /depotdata.  Working as user root on a Perforce server:

   cd /depotdata

   # If an sdp folder exists here, move it aside, e.g. to
   # sdp.MOVED_2014-09-11

   tar -xzpf sdp.Unix.2014.2.10649.tgz
   chown -R perforce:perforce sdp.Unix.2014.2.10649.tgz /depotdata/sdp

   cd /depotdata/sdp/Server/Unix/p4/common/bin

   # Copy 'p4', 'p4d', 'p4broker', 'p4web', 'p4p', etc. (only
   # those currently used) into this 'bin' folder.

   cd /depotdata/sdp/Server/Unix/setup
   vi mkdirs.sh
   # Review and adjustments to mkdirs.sh suit your environment.

   ./mkdirs.sh 1 -test

   Using 'mkdirs.sh' script with the '-test' flag as illustrated
   above will deploy to the SDP to /tmp/p4 rather than /p4 area.

   If working on the Production server directly, DO NOT forget
   to use the '-test' flag.

--------------------------------------------------------------------------
Upgrading the SDP on Windows:

   Install the SDP onto a different machine
    - configure sdp_master_config.ini 
    - run create_env.py

   Manually copy resulting files to the appropriate places in your existing
   installation.

--------------------------------------------------------------------------
Versioning the SDP:

   We strongly recommend that files in the following locations are 
   versioned in your local Helix server:

   On Unix:
      /p4/1/bin
      /p4/common

   On Windows:
      C:\p4\1\bin
      C:\p4\common
      C:\p4\config

   NEW: Helix DVCS and Streams features enable a new method for updating
   the SDP long-term, greatly simplifying the process of bringing in updates
   from The Workshop into your environment, and then merging into your local
   as-deployed SDP (locally configured and possibly customized).  It entails
   a straightforward 'p4 fetch' and 'p4 merge' process.

   For more information, see the hms_ts_setup.sh ship documentation.  This
   documentation is not complete as of this release, and is targeted for
   new deployments.  While the concepts can be retrofitted into any existing
   SDP installation, some custom procedures are required, as the scripts
   do not account for evolution of the SDP structure.  Contact
   consulting@perforce.com for more information.
