ArcGIS for Server 10.1 (including ArcSDE) and SQL Server 2012 problem with Create Enterprise-Geodatabase

Question

i have the following server system:

-Windows Server 2008R2 -SQL Server 2008 (SDE10 Enterprise Geodatabaees) and SQL Server 2012 on the the same machine -ArcSDE Application Server 10

First - Is that right, that i do not need to install the ArcSDE 10.1 for Microsoft SQL Server because we use direct connect on the client ?

Now i want to create with ArcGIS 10.1 a new ArcSDE 10.1 Enterprise Geodatabase on SQL Server 2012 with the "create enterprise geodatabase" tool. But i get an error messagge: Unknown errorNo extended error. I look at the sdedc_SQL Server.log:

DB_instance_open() db_connect error: -1 CAN'T OPEN INSTANCE: sde:sqlserver. Spatial Engine Connection Failed (-51). Cannot Get Access to Instance sde:sqlserver

Answer 1

SQL-Server 2012 support was introduced at ArcGIS 10.1 SP1. You must also have the required SQL-Server 2012 client library install (and its dependent .Net Framework 4.x components) on the ArcGIS 10.1 SP1 client.

Discussion on the "need to install ArcSDE" is more of a philosophical issue (vice technical), but you can read more about it in the Esri Forums.
