In Python you can use arcpy.ListUsers() or use the GDB Administration window by right-clicking on the database connection in ArcCatalog and choosing Administration > Geodatabase Administration
Thanks, I tried:
users = arcpy.ListUsers(ClientName)
and I got the error message:
Connection information provided was for a non-administrative user
With the command sdemon I was able to check the users connected using a schema owner account, it looks like with arcpy.ListUsers the account has to be SDE.
Thanks Jose, this tool only does work for the administrative user but this sounds like a good enhancement request to me.
However, it is it still possible to see users connected a few other ways. The simplest method is to do a selection from the Geodatabase process_information table. This should have the same information you were seeing from sdemon -o info -I users. This table by default is accessible through the public role, so any user will be able to select from it.
I know this goes without saying, but only selections should be run against this table, no edits.
Do I need to run any update to get the non-admin user ability: NIM096849?
Is there any sample using the Geodatabase process_information table to get the list of users.
NIM096849 isn't implemented in the software, it's just a request to include in a future release. If you contact support, we can add you to the enhancement, which adds more weight behind adding the functionality.
If you want to query the process_information table, you can follow my steps here. This table is owned by the GDB administrative user, so you may need fully qualify the table name. Keep in mind, I am showing Oracle for this one, but it will appear slightly different for SQL Server or PostgreSQL.
