[GIS] Appending from file geodatabase to ArcSDE fails using ArcPy

arcgis-10.1arcpyenterprise-geodatabasefile-geodatabase

I'm trying to append a feature class from a file geodatabase to an Arcsde featureclass using this line of code:

arcpy.Append_management("parcel_copy", sde_path+"parcel" ,"NO_TEST")

This line works under Python console in ArcMap , but when I execute it under Pyscripter IDE, all the code works fine except the append statement, and it does not return an error.

I have tried to isolate the append statements in a little script, and it worked, but i still don't understand why it has not worked.

i wonder if i have not deleted a featurelayer refering to a featureclass in SDE, that locks this featureclass, so i cannot append to it.

any explanation?

"parcel_copy" appears to be a layer in the Table of Contents of your map, so will be found when you run the script from ArcMap.

However, in order to let the script (when run outside of ArcMap) know where the data that layer is based on can be found, you will need to either issue MakeFeatureLayer before the Append, or more simply reference the path to the dataset in place of the layer name of the Append.

[GIS] How to transfer data and replica information from a file geodatabase to ArcSDE

I understand replicas a little better now and it turns out that I needed to replicate to an XML document when using the Create Replica Wizard in ArcMAP. I then send the XML Document to the person at the other end and they can use the Import -> XML Workspace Document within ArcCatalog to import both the data and replica information into their ArcSDE geodatabase. The geodatabase is published as a geodata service on the Internet and I can then synchronise the replicas.

This document on ESRI's arcgis.com site describes the process in more detail.

ArcPy – Copying ArcSDE Geodatabase to File Geodatabase Using ArcPy

I know this post is a little old but I though I would share my answer since I was faced with the same issue. The following script SHOULD copy all tables, feature classes and relationships not in a dataset and also will copy over all datasets including the feature classes, topology, etc within the dataset. It will skip over any errors durring the copy adn keep going. It will produce a log file that contains data such as the source DB item count and the destination item count so you can compare the copy and it will log errors it encounters as well.

def formatTime(x):
    minutes, seconds_rem = divmod(x, 60)
    if minutes >= 60:
        hours, minutes_rem = divmod(minutes, 60)
        return "%02d:%02d:%02d" % (hours, minutes_rem, seconds_rem)
    else:
        minutes, seconds_rem = divmod(x, 60)

    targetGDB = "DESTINATION_PATH\\SDE_Replicated.gdb"
    replicateDatabase(databaseConnection, targetGDB)

I had really good luck with this. I was replicating an SDE database to a file geodatabase. I haven't done too extensive of testing on this script though since it fulfilled all my needs. I tested it using ArcGIS 10.3. Also, one thing to note, I was in talks with someone that has used this script and they ran into an issue with an error copying certain datasets due to improper permissions and empty tables.

Lemur - why not create your relationships based to a global id instead of the object id? That you your relationships would be preserved. If you haven't created global id's I would highly recommend it.

-update

I added a little more logic into the code to handle bad database connection paths and better logging and error handling:
