Command syntax and parameters

Value | Description |
|---|---|
DB2ssid | Db2 subsystem ID or the name of the Db2 data sharing group to which the command applies. |
opertuneID | OPERTUNE system profile name (if OPERTUNE is running as a started task) or the batch job name (if OPERTUNE is running as a batch job). |
DISABLE | Keep Alive probing for this subsystem is disabled. |
ENABLE | TCP/IP Keep Alive configuration value is not overridden. |
value | The TCP/IP Keep Alive configuration value is overridden with the specified value. Specify a value in seconds of 1 to 65534. Avoid using very small values. KeepAlive detection is accomplished by probing the network based on the time that is entered in the KeepAlive parameter. A small KeepAlive value can cause excessive network traffic and system resource consumption. |
NORESET | The changes you request remain in effect until the Db2 subsystem is cycled. |
