Scripting an enterprise geodatabase upgrade in DB2

You can modify and use one of the Python scripts provided in this topic to connect to and upgrade an enterprise geodatabase.

The first scripts use an existing database connection file to connect to and upgrade a geodatabase.

The second script shows how you can provide connection information in the same script used to upgrade the geodatabase. This is especially useful if you do not have access to ArcGIS for Desktop; you can run the Python script from a computer where ArcGIS Engine with the Geodatabase Update extension or ArcGIS for Server (Standard or Advanced) is installed, provide connection information, and upgrade the geodatabase.

The connection you make to the geodatabase, whether as an existing database connection file or through parameters in the script, is a direct connection. You must have the following on the machine from which you will run the script:

Be sure you have read and performed the steps in Preparing to upgrade a geodatabase in DB2 before you upgrade.

Steps:
  1. Copy one of these example scripts to the Python window in ArcGIS for Desktop, or any Python IDE such as PythonWin or WING. Alter any variable values to match the information at your site.
    • If you have an existing database connection file that uses a direct connection and connects as the geodatabase administrator, copy and modify one of the following scripts, depending on your operating system:

      Default_gdb = "C:\\ArcGIS\connection_files\<Connection file>"
      
      # Process: Upgrade Geodatabase
