Upgrade a geodatabase in Informix

Available with Standard or Advanced license.

The goal of upgrading an enterprise geodatabase is to update the geodatabase system tables, stored procedures, types, and functions to take advantage of new functionality and bug fixes.

Install a new version of the ArcGIS client or apply a service pack, patch, or hot fix to an existing installation and upgrade the geodatabase.

Before you upgrade

When you upgrade any enterprise system, including a geodatabase, plan ahead. Test the new version on a development or test server to ensure that it works with all your client applications.

When you have determined that the new system works the way you expected, schedule the upgrade; be sure the necessary staff are available to perform the upgrade and that they have the permissions necessary to complete their assigned tasks.

Be aware of the following:

• If you are upgrading from 10.2.x, be sure to migrate all ArcSDE application server connections used in maps or services to connect directly to the geodatabase before you upgrade your geodatabase.
• Upgrades from beta versions of the software are not supported.
• You can upgrade directly from a 10.2.x, 10.3.x, 10.4.x, 10.5.x, or 10.6.x geodatabase if your database is at a supported release.
• If your geodatabase is at release 10 or earlier, you must first upgrade to a supported geodatabase release before you can upgrade to the current ArcGIS release.
• Once a geodatabase has been upgraded to the current release, ArcGIS 10 and older clients cannot connect to it.
• There is no formal mechanism to downgrade a geodatabase to a previous version. If after upgrading to a newer version you want to downgrade the geodatabase, you must restore the old database from a backup file.

The following is a checklist of steps to complete before you upgrade your geodatabase:

1. Read IBM Informix database requirements for ArcGIS 10.6.1 to confirm that Esri supports the Informix and ArcGIS version combination you want to use.
2. Check to see if your geodatabase can be upgraded. To do this, install the ArcGIS client version you want to move to onto a machine. If you install ArcMap, you can connect to the geodatabase and open the Database Properties dialog box to see if a geodatabase upgrade is possible. If you install ArcGIS Server (enterprise edition) or the ArcGIS Engine Geodatabase Update extension, you can use the ArcPy Describe function to determine if the geodatabase can be upgraded.

   # Open Python.
   cd /arcgis/server/tools
   ./python
   
   # Create a connection to the geodatabase.
   arcpy.CreateDatabaseConnection_management("/tmp/",
                                             "egdb_connection.sde",
                                             "INFORMIX",
                                             "myidsgdb",
                                             "DATABASE_AUTH",
                                             "sde",
                                             "mysdepassword",
                                             "SAVE_USERNAME")
   
   # Import ArcPy and check the geodatabase release.
   import arcpy
   
   isCurrent = arcpy.Describe('/tmp/egdb_connection.sde').currentRelease
   
   print isCurrent
   

   If false is returned, you can upgrade your geodatabase. If true is returned, you do not need to upgrade your geodatabase. Do not proceed with the subsequent steps.

3. Convert any application server connections used in existing maps or services to direct connections.
4. Create a backup of the database.
5. Remove any custom functionality you may have added to the geodatabase system tables outside ArcGIS, such as triggers or additional indexes.

   The upgrade procedure cannot accommodate customizations you make to the system tables. If such customizations prevent the alteration of a system table's schema, the upgrade will fail.

6. The informix user must grant dba privileges to the sde user account for the database through dbaccess.

   If you do not grant the required privileges, there will be problems with the upgrade procedure as well as overall product performance.

   The informix user issues the following command to grant dba privileges to the sde user:

   dbaccess <Database Name>
   Query-language-->New-->
   grant dba to sde
   Run
   

7. Make sure there are no connections to the geodatabase you are upgrading.

   To see a list of who is currently connected to your geodatabase, go to the Geodatabase Administration dialog box in an ArcGIS Desktop client.

You can now upgrade your geodatabase.

Upgrade the geodatabase

You can use the Upgrade Geodatabase tool in ArcMap or a Python script run on the ArcGIS client computer to upgrade your geodatabase.

Use the Upgrade Geodatabase tool

You can open the Upgrade Geodatabase tool from the Database Properties dialog box by clicking the Upgrade Geodatabase button on the General tab, or open the tool directly. If you open the tool from Database Properties, the Input geodatabase text box is prepopulated with the geodatabase connection information.

Esri recommends that you leave both the Pre-requisites check and Upgrade geodatabase options checked. That way, the tool checks to see if the prerequisites to upgrade have been met before continuing with the geodatabase upgrade.

The prerequisite check detects other active connections to the geodatabase, determines whether the connecting user has sufficient privileges to upgrade the geodatabase, ensures that the database can support XML columns, makes sure all datasets can be opened, and ascertains that the database and libraries are at the same release. If any prerequisites are not met, the tool terminates. You must correct any problems before you run the upgrade procedure again.

The results of this check are reported on the geoprocessing tool dialog box. If the check (or upgrade) fails, results are also written to the GDBUpgrade.log, which can be found in c:\Users\<user name>\AppData\Local\ESRI\<ArcGIS product>.

If all checks are passed, the tool proceeds with the upgrade. The status for the prerequisites check and the upgrade are shown on the geoprocessing tool progress dialog box. If the upgrade fails, information is written to the GDBUpgrade.log. Additional information is written to the sde_setup.log, which can be found in the system TEMP directory.

Run a script

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 sde user, copy the script that applies to your operating system, paste it into a text editor, alter it to use information specific to your site, save and close the file, then run it:

  # Name: upgradesdegdb_example.py
  # Description: Connect from a Windows computer 
  # with an existing database connection file 
  # and upgrade an enterprise geodatabase
  
  # 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
  
  # 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 the following script and provide your site-specific information at the command line:

  """
