Internal state reporting custom properties

You can use internal state reporting custom properties to control the timing of when dumps of internal state occur, if dumps are enabled, if compression is applied to the messages from the internal state, and so on.

When you change internal state reporting custom properties, you must restart your processes to use the most recently defined values.

bbson.DUMP_TIMEOUT custom property

Specifies the time, in minutes, between dumps of bulletin board over structured overlay network (BBSON) internal state. The default is to never perform a BBSON internal state dump. These state dumps go into the ProfileRoot/bbdumps/ directory. This property is only valid if you are using the WebSphere® Virtual Enterprise implementation of the bulletin board.

Table 1. bbson.DUMP_TIMEOUT custom property default, units, and scope
Scope Cell
Default 0 (never dump)
Units minutes

overlayNetStatsDumpPeriod custom property

Specifies the time, in seconds, between dumps of structured overlay network (SON) statistics. Set the value to 0 (the default) to disable dumps of SON statistics.

Table 2. overlayNetStatsDumpPeriod custom property default, units, and scope
Scope Cell
Default 0 (do not perform dumps)
Units seconds

son.compress custom property

Specifies if the compression of messages and network traffic from the SON is enabled.

Compression is enabled by default. To disable compression, set this custom property on the cell with a value of false.

Table 3. son.compress custom property default, valid values, and scope
Scope Set this custom property at the cell-wide level.
Default true (enabled)
Valid values true or false

son.FailNeighborAfterLostkHeartbeats custom property

Defines the number of missed heartbeats after which a neighbor process is considered to be in a failed or missing state.

Table 4. son.FailNeighborAfterLostkHeartbeats custom property default, valid values, and scope
Scope Set this custom property at the cell-wide level.
Default 6
Valid values Integer value greater than 0

son.NeighborHeartbeatPeriod custom property

Defines the time interval, in milliseconds, between heartbeat packets that are sent to neighbor processes.

Table 5. son.NeighborHeartbeatPeriod custom property default, valid values, and scope
Scope Set this custom property at the cell-wide level.
Default 20000 ms
Valid values milliseconds (ms)
