Create a geodatabase in Oracle—ArcMap

Available with Standard or Advanced license.

Prerequisites
You are the database and geodatabase administrator
The Oracle administrator configures the database; the geodatabase administrator creates the geodatabase

To create a geodatabase in an Oracle database, you run a geoprocessing tool or Python script from an ArcGIS client. Start by reading the prerequisites, then follow the instructions that apply to your situation.

Prerequisites

To create a geodatabase in Oracle, you need to do the following:

Confirm the ArcGIS, Oracle, and operating system combinations you want to use are compatible.
Obtain the Oracle client required to connect to the version of Oracle 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.
Determine who will create the geodatabase, as that affects who creates the database, and which tool you run to create the geodatabase. Follow the instructions that apply to your situation:
- You are the database and geodatabase administrator.
- The Oracle administrator configures the database; the geodatabase administrator creates the geodatabase.

You are the database and geodatabase administrator

If you perform the role of both the database administrator and geodatabase administrator and, therefore, know the password for both logins, you can use the Create Enterprise Geodatabase geoprocessing tool or Python script to create a geodatabase in Oracle.

The Create Enterprise Geodatabase tool makes it easy to set up a geodatabase because it creates the sde user, schema, and tablespace, and grants required privileges to the sde user for you. To achieve this, the tool uses the following default settings:

Creates a database user named sde
Creates a 400 MB tablespace in the Oracle default location and sets it as the sde user's tablespace
Grants the sde user privileges to create and upgrade a geodatabase, remove database connections, and import data using Oracle Data Pump (Not applicable to Oracle 11g)
Grants package privileges required to create a geodatabase
Creates a geodatabase

For more information on required privileges, see Privileges for geodatabases in Oracle.

Before you run the tool or script to create a geodatabase, you must set up Oracle.

Install and configure Oracle

Before you create a geodatabase, Oracle must be installed and configured. How you configure the Oracle instance depends on the specific needs of your organization. Consult the Oracle documentation for installation and configuration information.

Check the ArcGIS system requirements for Oracle before you set up a geodatabase to be sure the Oracle, ArcGIS, and hardware combinations you want to use are supported.

If you require the ability to do any of the following, you also need to configure the Oracle extproc to access the Esri ST libraries:

Execute ST_Geometry SQL functions from SQL clients.
Query the XML columns in the GDB_ITEMS_VW and GDB_ITEMRELATIONSHIPS_VW geodatabase system views.
Define a query layer in ArcMap or ArcGIS Pro that executes SQL functions on ST_Geometry columns.
Publish a web service that references data in the Oracle database.

After Oracle is installed and configured, install ArcGIS and Oracle clients.

Install and configure clients

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

In most cases, your ArcGIS client will be installed on a different computer than Oracle. Therefore, you must have a supported Oracle client on the ArcGIS client computer to connect to the Oracle instance. See the Oracle documentation to determine which version of the Oracle client you should install to connect to the version of Oracle you are using and for instructions on installing and configuring the client.

Install the ArcGIS client you want to use for geodatabase creation.
Follow the instructions provided in the software installation guides.
Install and configure an Oracle client on the ArcGIS client computer.
If you are connecting from a 32-bit ArcGIS client (such as ArcMap), you must install a 32-bit Oracle client. This is true even if you install the ArcGIS client application on a computer with a 64-bit operating system and the database and server operating system are 64 bit. If you are connecting from a 64-bit ArcGIS client (such as ArcGIS Server or ArcGIS Pro), you must install a 64-bit Oracle client.
You can obtain the Oracle Instant, Runtime, or Administrator Client from Oracle. See the Oracle documentation for instructions to install.
Set the environment variable of your operating system or user profile to include the path to and name of the directory where the Oracle client is installed.
- On Linux, set the LD_LIBRARY_PATH environment variable.
  You can obtain the Oracle Instant, Runtime, or Administrator Client from Oracle. See the Oracle documentation for instructions to install.
- On Microsoft Windows, set the PATH environment variable. If ArcMap is installed on the same Windows computer as ArcGIS Pro or ArcGIS Server, set the PATH variable to read the 64-bit client before the 32-bit client. For example, if your 32-bit Oracle client is installed to c:\Program Files (x86)\Oracle and your 64-bit Oracle Instant Client is installed to c:\Program Files\Oracle, add the following to the beginning of your PATH variable value: C:\Program Files\Oracle;C:\Program Files (x86)\Oracle;.
If your ArcGIS client was already running, restart it to recognize the Oracle client and new environment variables.
You can connect from ArcGIS to Oracle using an Easy Connect string. However, you must configure your Oracle database to allow Easy Connect strings. If you have the full Oracle client installed but want to use Easy Connect syntax to connect, be sure the sqlnet.ora file on the client is configured to allow the use of Easy Connect and the Oracle server is configured to allow Easy Connect syntax. See the Oracle documentation for further instructions.

Now you can create a geodatabase.

Create a geodatabase

You can run the Create Enterprise Geodatabase tool from ArcGIS Desktop (Desktop Standard or Desktop Advanced), or run a Python script from an ArcGIS Desktop, ArcGIS Server, or ArcGIS Engine client to create an sde user, schema, tablespace, and geodatabase.

Run the Create Enterprise Geodatabase tool

If you have access to ArcGIS Desktop, you can run a geoprocessing tool to create the geodatabase.

Follow these steps to create a geodatabase using the Create Enterprise Geodatabase tool in ArcMap:

Start an ArcGIS Desktop client.
Open the Create Enterprise Geodatabase tool.
You can search for or browse to this tool, which is located in the Geodatabase Administration toolset of the Data Management toolbox.
Choose Oracle from the Database Platform drop-down list.
Provide the information required to connect to the Oracle instance.
- If you have already configured the Oracle client to use a TNS network alias, type the Net service alias in the Instance text box.
- If you have not configured the Oracle client's network alias and your Oracle database and client are configured to use Easy Connect strings, provide the Oracle Easy Connect string in the Instance text box.
See Connect to Oracle from ArcGIS for a list of possible Easy Connect strings.

You must connect to the database as a database administrator to create the geodatabase administrator and tablespace. Therefore, the Database Administrator text box is populated with the sys user name.

Type the sys user's password in the Database Administrator Password text box.
Type sde in the Geodatabase Administrator text box.
If the sde user does not already exist in the database, the tool creates it and grants it the privileges necessary to create a geodatabase. If the user already exists, the required privileges are granted to it.
Type a password for the sde user in the Geodatabase Administrator Password text box.
If the sde user already exists in the database, be sure to type the correct password for the existing user; this tool will not change the password. If you are creating an sde user, the password you type is used when creating the sde user.
Specify a tablespace for the sde user.
- If you have a preconfigured tablespace to be used for the geodatabase repository, type its name in the Tablespace Name text box.
- If you want the tool to create a tablespace for you, type a valid name in the Tablespace Name text box and the tool creates a 400 MB tablespace in the Oracle default location. If you do not type a tablespace name, SDE_TBS tablespace is created and set as the default tablespace for the sde user.
To specify an Authorization File, browse to and choose the keycodes file that was created when you authorized ArcGIS Server Enterprise.
This file is written to the \\Program Files\ESRI\License<release#>\sysgen folder on Windows servers and /arcgis/server/framework/runtime/.wine/drive_c/Program Files/ESRI/License<release#>/sysgen on Linux servers. Copy the keycodes file to a location the tool can access. If you have not already done so, authorize ArcGIS Server now to create this file.
Click OK (ArcMap or ArcCatalog) or Run (ArcGIS Pro).

A geodatabase is created in your Oracle database.

Messages about geodatabase creation are written to 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 any problems creating a geodatabase, check this log file to troubleshoot the problem.

Next, if the Oracle database open_cursors parameter is set to anything other than 300, run the sde.gdb_util.update_open_cursors stored procedure to synchronize your Oracle database parameter with the geodatabase's setting.

Run a Python script

You can copy, save, and run the script provided here to create a geodatabase from ArcGIS Desktop (Desktop Standard or Desktop Advanced), ArcGIS Server, or ArcGIS Runtime (with the Geodatabase Update extension).

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

Save the file with a .py extension.
Run the script, providing options and information specific to your site.
In the following example run from a Linux machine, the file create_gdb.py is run for an Oracle instance with an SID of orcl. The instance is running on server gisprod. An sde user with password Tgdbst@rtsh3r3 is created, along with a tablespace named sde. A keycodes file in the default ArcGIS Server location is specified to authorize the geodatabase.
```
./create_gdb.py --DBMS ORACLE -i gisprod/orcl --auth DATABASE_AUTH -U sys
 -P N0pe3king! -u sde -p Tgdbst@rtsh3r3 -t sde -l '/usr/arcgis/server/framework/runtime/.wine/drive_c/Program Files/ESRI/License/sysgen/keycodes'
```
In this example, the same script is run from a Windows machine:
```
create_gdb.py --DBMS ORACLE -i gisprod/orcl --auth DATABASE_AUTH -U sys
 -P N0pe3king! -u sde -p Tgdbst@rtsh3r3 -t sde -l '\\Program Files\ESRI\License\sysgen\keycodes'
```
Tip:
Type -h or --help at the command prompt to get syntax help.

You now have a geodatabase in Oracle.

Messages about geodatabase creation are written to the sde_setup.log file, which is created in the directory specified for your TEMP or TMP variable on the computer where the tool is run. If you have any problems creating a geodatabase, check this log file to troubleshoot the problem.

The Oracle administrator configures the database; the geodatabase administrator creates the geodatabase

If the person creating the geodatabase does not have access to the database administrator's password, the database administrator can set up the database and sde user, and then the geodatabase administrator can connect to it using the sde login and create a geodatabase in the database using the Enable Enterprise Geodatabase geoprocessing tool or Python script.

The Enable Enterprise Geodatabase tool takes a database connection file as input and creates the geodatabase system tables, views, functions, and procedures in the sde user's schema.

Install and configure Oracle

Before the geodatabase administrator can create a geodatabase, the database administrator must do the following:

Install and configure an Oracle instance. How you configure the Oracle instance depends on the specific needs of your organization. Consult Oracle documentation for installation and configuration information.
Check the ArcGIS system requirements before you set up a geodatabase to be sure the database management system, ArcGIS, and hardware combinations you want to use are supported. See Privileges for geodatabases in Oracle for a list of required privileges.
Create an sde user and schema.
Grant the sde user the privileges necessary to create a geodatabase.
Create a tablespace for the sde user and set the tablespace as the sde user's default tablespace.
Grant execute privileges on packages needed for geodatabase creation. See Privileges for geodatabases in Oracle for a list of the packages.

If you require the ability to do any of the following, you also need to configure the Oracle extproc to access the Esri ST libraries:

Execute ST_Geometry SQL functions from SQL clients.
Query the XML columns in the GDB_ITEMS_VW and GDB_ITEMRELATIONSHIPS_VW geodatabase system views.
Define a query layer in ArcMap or ArcGIS Pro that executes SQL functions on ST_Geometry columns.
Publish a web service that references data in the Oracle database.

After Oracle is installed and configured, the geodatabase administrator can install ArcGIS and Oracle clients.

Install and configure clients

You can install ArcGIS Desktop (Desktop Standard or Desktop Advanced), ArcGIS Engine Geodatabase Update or ArcGIS Server to run a Python script and create a geodatabase. If you want to run the Create Enterprise Geodatabase geoprocessing tool instead of a script, install ArcGIS Desktop.

In most cases, your ArcGIS client will be installed on a different computer than Oracle. Therefore, you must have a supported Oracle client on the ArcGIS client computer to connect to the Oracle instance. See Oracle documentation to determine which version of the Oracle client you should install to connect to the version of Oracle you are using and for instructions on installing and configuring the client.

Install the ArcGIS client you want to use for geodatabase creation.
Follow the instructions provided in the software installation guides.
Install and configure an Oracle client on the ArcGIS client computer.
If you are connecting from a 32-bit ArcGIS client (such as ArcMap), you must install a 32-bit Oracle client. This is true even if you install the ArcGIS client application on a computer with a 64-bit operating system and the database and server operating system are 64 bit. If you are connecting from a 64-bit ArcGIS client (such as ArcGIS Server or ArcGIS Pro), you must install a 64-bit Oracle client.
You can obtain the Oracle Instant, Runtime, or Administrator Client from Oracle. See the Oracle documentation for instructions to install.
Set the environment variable of your operating system or user profile to include the path to and name of the directory where the Oracle client is installed.
- On Linux, set the LD_LIBRARY_PATH environment variable.
- On Windows, set the PATH environment variable. If ArcMap is installed on the same Windows computer as ArcGIS Pro or ArcGIS Server, set the PATH variable to read the 64-bit client before the 32-bit client. For example, if your 32-bit Oracle client is installed to c:\Program Files (x86)\Oracle and your 64-bit Oracle Instant Client is installed to c:\Program Files\Oracle, add the following to the beginning of your PATH variable value: C:\Program Files\Oracle;C:\Program Files (x86)\Oracle;.
If your ArcGIS client was already running, restart it to recognize the Oracle client and new environment variables.
You can connect from ArcGIS to Oracle using an Easy Connect string. However, the database administrator must configure the Oracle database to allow Easy Connect strings. If you have the full Oracle client installed but want to use Easy Connect syntax to connect, be sure the sqlnet.ora file on the client is configured to allow the use of Easy Connect and that the database administrator has configured the Oracle server to allow Easy Connect syntax. See the Oracle documentation for further instructions.

Now you can create a geodatabase.

Create a geodatabase

The geodatabase administrator can run the Enable Enterprise Geodatabase tool from ArcGIS Desktop (Desktop Standard or Desktop Advanced), or run a Python script from an ArcGIS Desktop, ArcGIS Server, or ArcGIS Engine client to create a geodatabase in the existing database.

Run the Enable Enterprise Geodatabase ArcGIS Desktop tool

If you have access to , you can run the Enable Enterprise Geodatabase tool to create a geodatabase.

Follow these steps to create a geodatabase using the Enable Enterprise Geodatabase tool in ArcGIS Desktop:

Start an ArcGIS Desktop client.
Connect to the Oracle database as the sde user.
Be sure to save the user's password on the Database Connection dialog box.
Open the Enable Enterprise Geodatabase geoprocessing tool.
Use the database connection you created in step 2 as the Input Database Connection.
Browse to the authorization 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 server where the software is installed. If you authorized ArcGIS Server on a Linux machine, the keycodes 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. If you have not already done so, authorize ArcGIS Server to create this file. Copy the keycodes file to a location the tool can access.
Click OK (ArcMap or ArcCatalog) or Run (ArcGIS Pro).

A geodatabase is created in the database.

If clients will access the geodatabase using SQL, configure the Oracle extproc to allow access.

Next, the database administrator can synchronize open_cursors settings between Oracle and the geodatabase using the sde.gdb_util.update_open_cursors stored procedure.

Run a Python script

If you want to create the geodatabase by running a script from an ArcGIS Server, ArcGIS Desktop, or ArcGIS Engine installation, you can use the script provided here.

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

Save the file with a .py extension.
Run the script, providing options and information specific to your site.
In the following example run from a Linux machine, the file enable_gdb.py is run for an Oracle instance with an SID of orcl. The instance is running on server gisprod. A keycodes file in the default ArcGIS Server location is specified to authorize the geodatabase.
```
enable_gdb.py --DBMS ORACLE -i gisprod/orcl --auth DATABASE_AUTH 
-u sde -p Tgdbst@rtsh3r3 -l '/usr/arcgis/server/framework/runtime/.wine/drive_c/Program Files/ESRI/License/sysgen/keycodes'
```
In this example, the same script is run from a Windows machine:
```
create_gdb.py --DBMS ORACLE -i gisprod/orcl --auth DATABASE_AUTH -U sys
 -P N0pe3king! -u sde -p Tgdbst@rtsh3r3 -t sde -l '\\Program Files\ESRI\License\sysgen\keycodes'
```
Tip:
Type -h or --help at the command prompt to get syntax help.

You now have a geodatabase in the Oracle database.

Messages about geodatabase creation are written to the sde_setup.log file, which is created in the directory specified for your TEMP or TMP variable on the computer where the script is run. If you have any problems creating a geodatabase, check this log file to troubleshoot the problem.

Next, the database administrator can synchronize open_cursors settings between Oracle and the geodatabase using the sde.gdb_util.update_open_cursors stored procedure.
