Prerequisite for deploying ARCSDE Service.
We haven't promoted using the "ArcSDE service model" in several releases. Instead, we promote the "direct connect model" when working with enterprise geodatabases. For a more detailed discussion, please see this thread,
Why would I install ArcSDE with 10.1?
Hope this helps,
Thanks for your reply. I understood your point but in case i wants to
proceed with deploying arcsde service (10.2.1) in arcgis server 10.4
machine, is there any hurdle????
As a general rule, we don't support installing different releases of the ArcGIS software on the same machine. In your case, the ArcSDE service 10.2.1 on a machine that already has ArcGIS Server 10.4 installed. This is NOT recommended.
Thank you Derek .I will not install arcsde in arcgis server machine.
As even though it is not required just for the sake of installing it i
will proceed with installation of Arcsde 10.2.1 on arcgis desktop 10.2.1
machine. I have arcsde 10.2.1 11g set up and underlying database is oracle
12 c. Is this a problem???
Oracle 12c was released later than ArcSDE 10.2.1, so I'm not sure if it will be fully compatible.
As I mentioned earlier, we haven't promoted using the "ArcSDE service model" in several releases so you don't need to install the ArcSDE software. To understand the difference between the "ArcSDE service model" and the "direct connect model", please see this older technical article,
1-Enterprise Geodatabase 101
(see the section titled Type of Client Connections)
This should help clarify the 2 connection models.
