Error The requested operation is unsupported by instance db FDO error: -2147155618 - Enable Network Topology

[RafaelFernandes_de_Souza]

Hello,

I am trying to configure a utility Network on a Oracle 19c db. 

After I create and configure a Utility Network and go to "Enable Topology" the error "The requested operation is unsupported by instance db" occurs, with FDO error: -2147155618.

I do not receive this error on SQL Server db.

Can anyone help me with this?

Paul,

We have contacted the support of Oracle. It seems to be some error on the sde tables.
I've asked them to create a new database to teste creating a new enterprise geodatabase and load the data from the old database of all other schemas, except sde.

I'll post here the results.

Thank you for the help.

Hi @RafaelFernandes_de_Souza - I have seen this error at a customer site.  Are you using custom CONFIG_KEYWORDS?  The issue for us appeared when we exported subnetwork, I believe the UNICODE_STRING field in one of the SDE tables should have been NVARCHAR instead of VARCHAR.  I can confirm the table later.  This was also Oracle 19C.

Hi @GeoffreyWest4 - I am using default config_keywords.

When I created a new instance in Oracle for test and created a new Enterprise Geodatabase, it works without any error.

I think that the problem can be what you said. the UNICODE_STRING field. 

Can you please tell me what table is?

Thank you for your help.
