You can use the administrative console to control the maximum amount of heap memory that is available for the underlying core group transport to allocate.
You should understand the following information:
The high availability manager consumes its allocated heap memory when it sends interprocess messages on behalf of other services that use the high availability manager functionality. For example, the heap memory might be consumed while sending memory-to-memory replication data, or highly available routing data from one core group member to another core group member.
The value that you specify for the Transport memory size property acts as a flow control mechanism that might affect the speed at which data is replicated or the speed at which routing data is made available to other core group members.
DCSV1051W, a high severity congestion event for outgoing messages DCSV1052W, a medium severity congestion event for outgoing messages DCSV1054W, a medium severity congestion event for incoming messages
Under extreme workloads, these messages might still occur on a properly tuned system.
To specify a value for this property, in the administrative console, navigate one of the following paths:
To change the amount of memory that is available for in-flight messages and network communication buffers, complete the following steps:
