As it is mentioned in ArcGIS Resources "PostgreSQL client libraries are required on the ArcGIS client application from which you will connect to the database".

My questions are:

  1. by ArcGIS client applications, they mean e.g. ArcGIS for Desktop version 10.1?
  2. Can ArcGIS for server 10.1 have a direct connection to e.g. Postgresql? and if NO why there is pg_client_linux64?

Are we supposed to put the client libraries in both bin directories of ArcGIS for Desktop and ArcGIS for server (on Centos)?

  1. Yes.
  2. Yes.
    a. See ESRI help configuring one machine arcgis for server (Linux).
    b. See also database connections in arcgis desktop for specific Postgres instructions
  3. Yes see ESRI help setting up a connection in PostgreSQL.
    You would need to connect from desktop and copy the connection file to the server.
    a. You also need to register the database with arcgis for server.
    See ESRI help registering the database with th server

Thank you Brad. by Registering the database with arcgis for server, they meant basically ArcGIS for server and ArcGIS for Desktop have access to e.g. postgresql database? I thought only ArcGIS for Dsktop has access to database and we need to add another database on the server so that we can lets say make interactive maps – KDot1254 Aug 26 '13 at 14:46
