Distributed Installation
A distributed installation describes an environment where more than one instance of the K2 connect Server Service or more than one Developer machine is required that may be clustered and share the same database. Each time a K2 Five and K2 connect Server is added, this requires an individual K2 connect Server license. The available options for distributed installations are listed below and are divided into two categories:
- Multitiered: Multitiered environments may contain more than one K2 connect Server but the work load is not load balanced. The developer machines reference the same SQL Server Instance, databases and Service Object Repository. In a Development / Production environment, if you want to publish service objects from one server to the other you have to use the same K2 connect 5.0 User Guide database. Open the Connect Admin tool and look at the SQL connectionstring to see that they are the same.
- Clustered Environments: A clustered environment requires at least two K2 Five Servers to be already configured in a clustered configuration. Each of the K2 Five Servers will require K2 connect Servers and licenses per service instance.
For option 2, all K2 Five Servers require a K2 connect Server license to ensure that the cluster configuration is able to service calls regardless of which machine handles the task. The absence of the K2 connect license on all machines will result in exceptions preventing the cluster from handling the service call.
How to configure the above environments
The tables below describe how to configure Multitiered and Clustered environments and lists the primary components of a distributed K2 connect installation.
Installed on the K2 Server:
| Server Orientated | |
|---|---|
|
K2 connect Server Service |
The K2 connect Server Service is installed on the same machine as the K2 Five Server and is licensed for use per machine. |
Installed on a K2 Client Machine:
| Tools - Client Orientated | |
|---|---|
| K2 connect Administration | Tools installed to administer K2 connect destinations. |
| K2 connect Client Tools | Installed for Client Administration. |
| Service Object Designer | Development tools required to develop and publish Service Objects. |
Installed on the SQL Server Machine:
| Data Storage | |
|---|---|
| K2 connect database | Installed on the SQL Server. The K2 connect database is installed once, any additional client machines would point to the same K2 connect database. |
Installation Steps
Before installing K2 connect for SAP, ensure the Installation Prerequisites have been met and the manual configurations are done. Use these step by step instructions as the base for a distributed installation:

Component Options
Select the component to be installed. This type of installation installs only one of the K2 connect components and is used when installing a distributed environment. When more than one K2 connect Server is being installed, only one instance of the K2 connect database is required which will be created by enabling the Create new SQL Database option when installing the first K2 connect Server. If this is not the first K2 connect Server, then disable the Create new SQL Database option. The Custom Installation option is only used with Standalone Installations.

| Where to Install | ||
| Where to install | K2 connect Server | On the same physical machine as the K2 Five server. Each K2 connect Server installed will require an individual license |
| K2 connect ServiceObject Designer | On a development machine. The development machine is dependent on the server components, so a local copy of the K2 connect Server will be installed. It does not however need to be started if a K2 connect Server service instance is up and running. If the local instance is required, then an additional license would be required. |
|
| K2 connect Client Console | On a development machine or client machine. | |
| Custom Installation | This option enables a custom configuration. It is recommended that this option only be used to install a standalone scenario. All distributed requirements are catered for in the above options. | |

Database Connections
The database connection screen requires the SQL Server and K2 connect database names, including the accounts that will be used to access the SQL Server and create the required database. The account used at this point is the logged on user. If this account does not have the appropriate permissions, this portion of the installation will fail. This screen will not be available if the K2 connect Client Console option was selected on the previous screen of the installation manager.
