Update to Session Integrator adds flexibility in locating resources

This update adds flexibility to how Session Integrator locates resources. This functionality is implemented by using the following registry subkey:

Registry location: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\siserver\Parameters\ResLocFlags
Key type: DWORD
Value name: DMODReslocate
Value data: N

If the Value data field is set to 1 = RLOC_RANDOM_ORDER.
If the value is not set, a default value of 4 = RLOC_LOCAL_SERVICE is used.

Important The registry is read one time when the SI Server (siserver.exe) is started.

This update is included in the following cumulative updates for Host Integration Server:

Cumulative Update 2 for Host Integration Server 2016

Cumulative Update 4 for Host Integration Server 2013

SI Server is hard-coded to use RLOC_LOCAL_SERVICE for the ResLocFlags.

If the service uses RLOC_RANDOM_ORDER, it will then check the ST for each new connection.

SI Server is updated to enable configuration of ResLocFlags through a registry subkey.

With the default setting DMODReslocate=4, the behavior is as follows:

• Normal operation: SI application uses local SI Server and Node.

• Local Node Paused: SI application uses Local SI Server and Local Node.

• Local Node Inactive: SI application uses Remote SI Server and Remote Node.

• Local SI Server Disabled: SI application uses Remote SI Server and Remote Node.

With DMODReslocate=1, the behavior is as follows:

• Normal operation: SI application uses local SI Server and Node.

• Local Node Paused: SI application uses Local SI Server and Remote Node.

• Local Node Inactive: SI application uses Local SI Server and Remote Node.

• Local SI Server Disabled: SI application uses Remote SI Server and Remote Node.
