Data type String
- Allow activation
Select if high availability group members can be activated on this appserver.
- Is alive timer
Timeime interval, in seconds, at which the high availability manager will check the health of all of the active high availability group members running in this application server process. An active group member is a member that is able to accept work. If a group member fails, the appserver on which the group member resides is restarted. If -1 is specified, the timer is disabled. If 0 (zero) is specified, the default value of 120 seconds is used.
The value specified for this property can be overridden for the high availability groups using a particular policy if the Is alive timer property for that policy specifies a different time interval. If the Is alive timer setting specified for a policy is greater than 0 (zero), the high availability manager uses that time interval, instead of the one specified at this level, when determining how frequently it should check the health of a high availability group member using that particular policy.
Data type Any integer between -1 and 600, inclusive Default 120 seconds
- Transport buffer size
- Buffer size, in megabytes, of the underlying group communication transport. The minimum buffer size is 10 megabytes.
Data type String Default 10 megabytes
