ArcGIS Help 10.2 - Scripting a geodatabase upgrade in PostgreSQL

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

The first set of 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 using 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:

An ArcGIS client, either ArcGIS for Desktop (Standard or Advanced), ArcGIS Engine Runtime with the Geodatabase Update extension, or ArcGIS for Server Enterprise (Standard or Advanced)
Be sure to authorize the ArcGIS client before you run the script.
The PostgreSQL client libraries must be placed in the bin directory of your ArcGIS client.

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

Steps:

First, check if the geodatabase can be upgraded.
1. Open Python.
  cd /arcgis/server/tools ./python
2. Use the Describe function to find if your geodatabase release matches your ArcGIS client release.
  import arcpy isCurrent = arcpy.Describe('/tmp/egdb_connection.sde').currentRelease print isCurrent
If false is returned, you can upgrade your geodatabase. Proceed to the next step. If true is returned, you do not need to upgrade your geodatabase.

To upgrade the geodatabase, copy one of these example scripts into a text editor. 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:

# Name: upgradesdegdb_example.py
# Description: Connect from a Windows computer 
# with an existing database connection file 
# and upgrade an enterprise geodatabase in PostgreSQL
# Author: Esri

# Import arcpy module
import arcpy
 
# Local variables:
Output_Workspace = "C:\\ArcGIS\connection_files\<Connection file>"
Default_gdb = "C:\\ArcGIS\connection_files\<Connection file>"

# Process: Upgrade Geodatabase
arcpy.UpgradeGDB_management(Default_gdb, "PREREQUISITE_CHECK", "UPGRADE")

# Name: upgradesdegdb_example.py
# Description: Connect from a Linux or UNIX computer 
# with an existing database connection file 
# and upgrade an enterprise geodatabase in PostgreSQL
# Author: Esri

# Import arcpy module
import arcpy
 
# Local variables:
Output_Workspace = "<user>/connections/<Connection_file>"
Default_gdb = "<user>/connections/<Connection_file>"

# Process: Upgrade Geodatabase
arcpy.UpgradeGDB_management(Default_gdb, "PREREQUISITE_CHECK", "UPGRADE")

If you do not have a database connection file on the computer from which you are scripting the upgrade, you can copy and modify the following script:

"""
Name: upgrade_gdb.py
Description: Provide connection information to an Enterprise geodatabase 
and upgrade the geodatabase
Type upgrade_gdb.py -h or upgrade_gdb.py --help for usage
Author: Esri
