Arcpy - Create an Historical Marker on an archiving enabled dataset in Oracle SDE

[MaximeDemers]

Hi,

I am looking for a way to create an Historical Marker programmatically with arcpy v.10.3. The archiving is enabled on a dataset in Oracle SDE.

I think, it's related with arcpy Version Toolset, but I can't find the documentation about this.

First is it possible to create Historical Markers with arcpy? If yea, any tip about this would be appreciated.

Thank you,

Maxime

Hi Maxime

To create a Historical Marker from Python, an option is using comTypes. Following  the next steps, you can create Historical Markers in a Enterprise Geodatabase from Python:

Environment: ArcGIS for Desktop 10.4.1 + Python 2.7

1. Install comtypes-0.6.2.win32.exe (attached)
2. Go to comtypes folder in "C:\Python27\ArcGIS10.4\Lib\site-packages\comtypes", and delete the automation.pyc, automation.pyo, safearray.pyc, safearray.pyo files.  Edit the file automation.py and insert POINTER(BSTR): VT_BYREF|VT_BSTR, in the _ctype_to _vartype dictionary.  

•                          

   3.  Delete all files in C:\Python27\ArcGIS10.4\Lib\site-packages\comtypes\gen

   4. Copy the file Snippets.py (attached), into C:\Python27\ArcGIS10.4\Lib

   5. From Python Script you must to implement a function to create the Historical Marker.  (the example in the test.py file) 

   

   Hope this helps,
