Create a geodatabase in Db2

Available with Standard or Advanced license.

Install and configure IBM Db2 and an ArcGIS client and use the Enable Enterprise Geodatabase geoprocessing tool or a Python script to create a geodatabase in a Db2 database.

This topic covers creating a geodatabase in Db2 on Linux, UNIX, or Windows servers. For instructions on creating a geodatabase in Db2 on the z operating system (z/OS), see Create a geodatabase in Db2 z/OS.

Prerequisites

Before you create a geodatabase in Db2 on Linux, UNIX, or Windows, you need to do the following:

• Confirm the ArcGIS, Db2, and operating system versions you want to use are compatible.
• Obtain the Db2 client required to connect to the version of Db2 you'll use to store your geodatabase.
• Obtain an ArcGIS Server keycodes file and place it in a location you can access from the ArcGIS client you'll use to create the geodatabase.
• Install and configure Db2.

Install and configure Db2

Before you can run the Enable Enterprise Geodatabase tool or script to create a geodatabase in Db2, you (or your IT department or database administrator) must install and configure the Db2 database management system.

You should follow the instructions provided by IBM to install and configure your Db2 instance. Then follow these steps to configure a database and login to use for your geodatabase.

1. Create an operating system login named sde on the Db2 server.

   You will connect to the database with the sde login to create a geodatabase.

2. Create a Db2 database and register it with the Spatial Extender module.
3. Grant the sde user DBADM authority in the database.

Next, set up an ArcGIS client from which you will connect and create a geodatabase in the Db2 database.

Configure clients

You can run a Python script from ArcGIS Desktop (Desktop Standard or Desktop Advanced), ArcGIS Engine Geodatabase Update, or ArcGIS Server (enterprise edition) to create a geodatabase. If you want to run the Enable Enterprise Geodatabase geoprocessing tool instead of a script, use ArcGIS Desktop.

Note:

You need an ArcGIS Server (enterprise) keycodes file to authorize your geodatabase in the next section. Even if you do not run a Python script from an ArcGIS Server machine to create the geodatabase, you must install and authorize ArcGIS Server to get the keycodes file. You may need to copy the file from the ArcGIS Server machine to a location the geoprocessing tool or Python script can access.

1. Install the ArcGIS client you want to use for geodatabase creation.

   Follow the instructions provided in the software installation guides.

2. In most cases, your ArcGIS client will be installed on a different computer than the Db2 server; therefore, install and configure a Db2 client on the ArcGIS client computer.

   You can download the IBM Data Server Runtime Client for Db2 from My Esri, or you can use your own installation of the Db2 client. See the Db2 documentation for instructions to install. If you are installing the Db2 client on a 64-bit operating system, run the 64-bit executable; it installs both 32- and 64-bit files, allowing you to connect from both 32- and 64-bit ArcGIS clients.

3. You can connect from ArcGIS to a Db2 database using a DSNless connection string. However, if you want to use a data source name to connect instead, you must catalog the database, thereby configuring the data source name. See the IBM Db2 documentation for instructions on creating a data source name.

Now you can create a geodatabase.

Create a geodatabase

Use one of the following methods to create a geodatabase in your Db2 database:

Use the Enable Enterprise Geodatabase tool

If you installed and configured ArcGIS Desktop to connect to your Db2 database, you can run the Enable Enterprise Geodatabase tool.

Follow these steps to create a geodatabase from ArcMap:

1. Start ArcMap or ArcCatalog.
2. Connect to the Db2 database. Connect with the sde login.

   Be sure to save the sde user's password on the Database Connection dialog box.

3. Right-click the database connection and click Enable Geodatabase.

   The Enable Enterprise Geodatabase tool opens.

4. Add the database connection file for your Db2 database to the Input Database text box.
5. Browse to the ArcGIS Server keycodes file that was created when you authorized ArcGIS Server and add it to the Authorization File text box.

   When you use the wizard to authorize ArcGIS Server, a keycodes file is written to the machine where the software is installed. If you authorized ArcGIS Server on a Linux box, the file was created in /arcgis/server/framework/runtime/.wine/drive_c/Program Files/ESRI/License<release>/sysgen. If you authorized on a Windows server, the file was created in Program Files\ESRI\License<release>\sysgen. Copy this file to a location you can access from the Enable Enterprise Geodatabase tool. If you have not already done so, authorize ArcGIS Server to create this file.

6. Click OK to run the tool.

   You can find messages related to geodatabase creation in the sde_setup.log file, which is created in the directory specified for your %TEMP% variable on the computer where the tool is run. If you have problems creating a geodatabase, check this file to troubleshoot the problem.

A geodatabase is created in your Db2 database.

Next, create users to load data into the geodatabase. See the IBM Db2 Information Center for instructions on creating users.

Use a Python script

You can run a Python script from an ArcGIS Desktop (Desktop Standard or Desktop Advanced), ArcGIS Server (enterprise edition), or ArcGIS Engine Geodatabase Update client machine to create a geodatabase in a Db2 database.

Follow these steps to run a Python script for geodatabase creation in a Db2 database:

1. Create a text file on the ArcGIS client machine and copy the following script into the file.

   """
   Name: enable_enterprise_gdb.py
   Description: Provide connection information to an enterprise database
   and enable enterprise geodatabase.
   Type enable_enterprise_gdb.py -h or enable_enterprise_gdb.py --help for usage

2. Save the file with a .py extension.
3. Run the script, providing options and information specific to your site.

   In the following example run from a Windows machine, the file enable_gdb.py is run for database spdata on instance db2prod. The connection is made as the sde login with password Tgdbst@rtsh3r3. A keycodes file in the default ArcGIS Server location is specified to authorize the geodatabase.

   enable_gdb.py --DBMS DB2 -i db2prod --auth DATABASE_AUTH 
   -u sde -p Tgdbst@rtsh3r3 -D spdata -l '\\Program Files\ESRI\License\sysgen\keycodes'
   

   This is an example of running the script on a Linux machine:

   /enable_gdb.py --DBMS DB2 -i db2prod --auth DATABASE_AUTH 
   -u sde -p Tgdbst@rtsh3r3 -D spdata -l '/usr/arcgis/server/framework/runtime/.wine/drive_c/Program Files/ESRI/License/sysgen/keycodes'
   

   Tip:

   Type -h or --help at the command prompt to get syntax help.

   You can find messages related to geodatabase creation in the sde_setup.log file, which is created in the directory specified for your TEMP or TMP variable on the computer where the Python script is run. If you have any problems creating a geodatabase, check this file to troubleshoot the problem.

A geodatabase is created in your Db2 database.

Next, create users to load data into the geodatabase. See the IBM Db2 Information Center for instructions on creating users and granting privileges to load data.
