Reaching State Zero Without Losing Your Versions

STATE 0

Reaching State 0 without losing your Versions

Agenda

• Introduction

• Business Drivers

• Technology

• Questions?

SSP Innovations

Nine year old GIS and WMS consulting company based in Denver, CO

area

• Work exclusively in the United States utility industry

• Includes Electric, Gas, Water, Wastewater/Sewer, Fiber

Strong partnerships with Esri and Schneider Electric

• Certified to implement/integrate/customize entire Esri & SE GIS suite

• Also do GDB consulting & WMS consulting/implementations

Began working with IREA 2/12: implementation of SSP-All Edits Report

• Have since partnered on several projects (upgrades, custom reporting in Designer,

custom support, education services)

The Problem

NAD27 to NAD83

Costs for new data

Base Map data in ArcMap

GPS Transformations

ArcGIS Online

Needed State 0 to transform the projection

300+ design versions

Rebuilding the network

Production down time

“Hatching the Plan”

ESRI UC 2012

ArcGIS Online – the future of IREA’s GIS system

Constant communication between IREA, Schneider Electric (formerly known as Telvent), and SSP Innovations

“Why can’t we export the designs to XML and just replay the versions back in place?”

“This might work…”

Engine Viewer with Redliner

Save Redline sessions to XML

Replays the session edits to the Enterprise GIS

Telvent Design XML Tools

Export/import capabilities for designs using XML

Works on both WFM and GIS side

SSP All Edits

Stores all edit actions in database

Has graphic display of edit locations

Decision Point

SSP added feature classes to All Edits

Not just graphic representation of edits

Replay old versions

Key to IREA State 0 Project

SSP Nightly Batch Suite

Provided the processing engine for the project

Implementation Environments

Technology

How did we came up with the solution?

• Utilizing two of our tools:

• Night Batch Suite

• All Edits Tool

• The majority of the work was already done by our All Edits Tool

• Reconciles a version and gets differences

• Writes those differences to the database

• Read those differences back from the database.

• The remainder of the work was taken care of by the Night Batch

Suite.

• Write version to the database

• Recreate version from the database

• Update designs’ xml

State 0 Plan

• Reproject Data over a weekend time frame.

• Freeze production by COB on Thursday

• Start preparation on Thursday.

• Run processes over the weekend

• Get users back in the system first thing Monday morning

Preparation

Preparation

• Deployed tools

• Backed up production database

• Copied production to a temp database (IGISTEMP)

• Configured tables and feature classes to host data

• Started processes

State 0 Surgery

Write Versions to Database (242 versions)

• Started process around 5:00pm on Thursday

• Total processing time: 8 hours and 15 minutes

• Checked log file first thing Friday morning.

• Reprocessed any versions with errors (4)

• Reran Write Versions to DB

Get to State 0

• Somewhat a manual process

State 0 Surgery

• Exported ArcFM Configuration (XML)

• Used python script to delete all relationships

• At this point we were at State 0 and ready to reproject the data

• Created IGISNEW database for reprojection

• Re-projected data from NAD27 to NAD83

Put it back together

Rebuilt the Database

• Recreated relationships using python script

• Rebuilt geometry network

• Set privileges and re-versioned database

• Converted objects to ArcFM and Designer

• Swizzled Store Display to point to the new database

• Imported ArcFM Configuration

• Kicked off CreateVersionsFromDB batch application

Put it back together

If Schneider Electric Designer shop

• Update the design graphics

• Manually rebuilt Composite Favorites

State 0 Workflow

State 0 Statistics

IREA’s Versions tree

NAD83 Coordinate System

IREA & SSP Innovations

The users never knew anything had changed

Challenges – Composite Favorites

Composite Favorites:

Store relative feature placement

Store the projection in the record

Stored as HUGEBLOB data type

Solution:

Create session in old database

Place all Composite Favorites

Process the State 0 and Re-Projection

Recreate composite favorites from session

Challenges – Index Rebuild

Two methods for Object Classes in new database:

Create brand new w/ ArcCatalog

Copy from old DB to new DB

If copied from old DB,

Rebuild indexes after relationships are created.

Challenges – User Stored MXD

Two Check Items Here:

Correct database source on any stored layers

Change Data Frame coordinate system

Challenges – Double Check Logs

Overnight CreateVersionFromDB

Process bumped off NW

Proceeded with rebuilding

Processed missing versions

Did not notice error in log

Did not verify version count

Discovered missing versions

Rebuilt the lost versions

Processed bad version later

Moral of the story: Check your logs or ….

The project goes from heart surgery to brain surgery
