Hello, and welcome to the ESRI Instructional Series Podcasts. My name is Olena Smith. I work in

Educational Services at the ESRI Washington D.C. office. I specialize in ArcSDE technology and geodata

management.

This is the first podcast in a series of podcasts on implementing and managing desktop and workgroup

geodatabases. I am going to talk about the desktop geodatabase, also known as a personal ArcSDE

geodatabase. In addition, I am going to talk about the workgroup geodatabase, also known as workgroup

ArcSDE geodatabase. Both are ArcSDE geodatabases implemented on SQL Server Express. A

prerequisite for this podcast is that you should already know what the geodatabase is. The intent of this

series of podcasts is to help you set up and administer desktop and workgroup geodatabases. This series is

tailored for ArcGIS users that are responsible for desktop or workgroup geodatabase installation,

administration, and maintenance. This podcast will concentrate on the installation process of ArcSDE

technology for Microsoft SQL Server Express licensed for ArcGIS Desktop or ArcGIS Server

Workgroup.

Desktop and workgroup geodatabases are very similar, except for the total number of supported

concurrent users. Desktop geodatabases support three concurrent connections, while workgroup

geodatabases support 10 concurrent connections. Both were designed to enable users to easily set up and

maintain an ArcSDE geodatabase without having to perform administration tasks using database

management tools.

The installation and management of ArcSDE geodatabases on SQL Server Express is a simple procedure.

First, you need to install the ArcSDE technology software supplied by ESRI, then use ArcCatalog to

create, administer, and maintain the geodatabases.

Let’s talk about installation.

The SQL Server 2005 Express Database Management System (DBMS) is installed first. It is a free

DBMS platform made by Microsoft and included with both ArcEditor and ArcInfo levels of ArcGIS

Desktop and ArcGIS Server Workgroup. The installation of SQL Server 2005 Express is part of the

ArcSDE technology installation.

There are a few things you need to keep in mind about SQL Server 2005 Express.

It supports 1 GB maximum of RAM, and utilizes one CPU. Even if the machine has more than one CPU,

SQL Server Express will utilize only one CPU of those that are available.

A full list of the prerequisites, software and hardware requirements for SQL server 2005 Express

can be found on the Microsoft support site, http://support.microsoft.com, KB article 910229,

titled SQL Server 2005 Express Edition Readme.

During the installation of SQL Server 2005 Express, the wizard will take you through a set of panels to

configure the DBMS instance. We recommend that you to accept all the defaults. However, I think it is

important to understand what you are installing. Therefore, the following discussion is on a few panels

you’ll encounter during SQL Server 2005 setup.

Configuration system check . Is your machine ready to host SQL Server 2005 Express? If yes,

you’ll see all the green checks; if not, you will see some red Xs, which means you have to take

care of those other components before proceeding with SQL Server 2005 Express installation.

Feature selection. If you’re familiar with SQL Server, you might choose to install the

Management Studio Express feature (a graphical user interface with interactive management tools

for SQL Server Express). Nevertheless, please note that it’s NOT supported by ESRI to alter

ANY table, stored procedure, or setting via Management Studio. Seasoned SQL Server

users\DBAs may utilize Management Studio Express to automate backups, for instance; but a

backup tool, as well as all other database maintenance tools, also exist in ArcCatalog.

One of the further panels is called Instance Name. SQL Server instance name, often referred to

as SQL Server name, must be unique on the entire network. It’s composed of the machine name

and a user-defined name. Multiple instances of SQL Server may exist on one machine. The first

instance of SQL Server Express by default, is machine name\SQL Express. If you desire, you

may change SQL Express to something more meaningful for you, like a name of your

department, for example. All consecutive instance names must be unique. If you’re installing

multiple instances on one machine and do not recall all the previous instance names used, you

may click the Installed Instances button on the Instance Name panel to see the full list of SQL

Server instances on the machine.

Authentication Mode panel. Authentication is what the DBMS uses to check your credentials

(that you are who you are). SQL Server Express supports two types of authentication: Windows

and Mixed Mode. Windows authentication uses the same login as you provided when you logged

into your workstation: domain name\user name. Windows authentication is generally more

secure, as it passes an access token rather than user name and password. Mixed-mode

authentication allows for both types of users: Windows-authenticated and database-authenticated

users to connect to the database. Desktop and workgroup geodatabases do not support database

authentication, as it would require the use of database management tools to create logins and

users. Therefore, accept the default on the Authentication panel, which is Windows

Authentication.

Once SQL Server Express is installed, the wizard will prompt you to go through the ArcSDE post

installation. If you already had an instance of SQL Server Express installed, then you would have

immediately started with the post installation when you ran the ArcSDE technology software installation.

The ArcSDE Post Installation wizard is composed of one panel for desktop installations and two panels

for workgroup installations.

On the first panel, which is common to both installations, you need to choose an instance of SQL

Server Express; typically it’s the one you just created. Click the pull-down list next to the SQL

Server instance name and select an appropriate instance. You may also add another administrative

account to the instance. It is an optional step in case you want another user to have admin

permissions to the same instance of SQL Server Express. You can always add additional admin

users via ArcCatalog later on.

The part that is only applicable for workgroup installations is the authorization of SQL Server

Express instance with an ESRI Copy Protected License Information File (ECP) file.

You have to obtain the file from ESRI. If you don’t have an ECP file and don’t know

how to get one, refer to ESRI support site http://support.esri.com, KB article 32222,

titled “HowTo: Get an authorization file for ArcSDE 9.2 to register it for use.” It is

also applicable for ArcSDE 9.3.

Once applied, the content of the file is stored at the SQL Server Express instance

level, later in the geodatabase and all connections will check for valid authorization.

This file contains a license expiration date, which means no one will be able to

connect to the geodatabases on that instance of SQL Server Express past the date.

You can open the file with any text editor to take a note of the date. I’d recommend

you to create a reminder, perhaps a Microsoft Outlook calendar reminder, to update

the license with a new ECP file prior to expiration.

Desktop installation will not ask you for an ECP file because it is licensed with ArcEditor or

ArcInfo level of ArcGIS Desktop license.

Now all the software is installed. You’re ready to create and manage your ArcSDE geodatabases on SQL

Server Express instance, which is the topic of the next podcast in the series.

In conclusion, the installation of desktop and workgroup geodatabases on SQL Server Express is

relatively easy. First you install the DBMS, which is SQL Server 2005 Express, typically accepting all the

defaults parameters. Then you step through the ArcSDE technology post installation. If you are installing

workgroup software, you will also need to reference an ECP file from ESRI.

For more information, you may consult with the ArcGIS Desktop Help, main ESRI Web site, and other

instructional podcasts on geodatabases. Additional information is available at the ESRI support site

http://support.esri.com, at the Geodatabase blog http://blogs.esri.com/, and at the ESRI Resource Center

http://resources.esri.com. When at blogs.esri.com, you will need to click Inside the Geodatabase to get to

the Geodatabase blog. On an ending note, the Resource Center is new with the release of ArcGIS 9.3, and

it is a centralized portal to all support resources.

Thank you for listening and stay tuned for future podcasts.
