Connections Manipulator Manager
This manager is responsible for managing client connections to the cluster. It provides a set of properties for managing the pools where the TCP connection objects are stored.
The Connections Manipulator Manager runs on dispatchers only.
The Connections Manipulator Manager provides several more properties. We recommend that you do not edit any of its properties unless explicitly advised by SAP support.
Dispatcher
Property |
Description |
Default Value |
MaxParallelUsers |
Defines the maximum number of connections that can be processed in parallel. When this number is exceeded, new connections are rejected. These are all connections, not only the ones for a specific application or protocol, so when the limit is reached nothing else will be available as well. The value of this property is automatically calculated on the basis of the MaxHeapSize. However, if you want to define a particular number of users to work on the dispatcher, you can set your own values. If your desired value is bigger than the maximum value the dispatcher can handle, the system sets its maximum value instead of yours. If your value is less than the maximum value the dispatcher can handle, the system accepts your value. If the value is 0, the system sets its maximum value. |
0 |
GetStreamsSoTimeout |
A socket timeout for the I/O stream of a client socket. |
10000 |
CloseWaitCheckPeriod |
The number of availability checks for a connection after which the system performs a check whether the connection is in close-wait status, that is, if the connection is closed on the client side but is still open on the server side. If the result of this check is positive, the system closes that connection on the server side, too. |
