TABLE 52 Environment - HL7 Inbound Adapter - TCPIP Inbound Settings
Name Description
Steady Pool Size An integer indicating the minimum number of message–driven beans to
maintain. When the value is set to a number greater than 0 (zero), the container
pre-populates the MDB pool with the specified number and tries to ensure that
there are always this number of beans in the free pool. This ensures that there are
enough MDB beans in the ready-to-serve state to process user requests.
This property does not necessarily guarantee that no more than steady-pool-size
instances exist at a given time. It only governs the number of instances that are
pooled over a long period of time. For example, if an idle stateless session
container has a fully-populated pool with a steady-pool-size of 10 and 20
concurrent requests arrive for the MDB component, the container creates 10
additional instances to satisfy the burst of requests. The advantage of this is that it
prevents the container from blocking any of the incoming requests. However, if
the activity is reduced to 10 or fewer concurrent requests, the additional 10
instances are discarded.
Max Pool Size An integer indicating the maximum number of message–driven beans in the
pool. A value of 0 (zero) indicates that the pool is unbounded.
Pool Idle Timeout in
Seconds The maximum amount of time (in seconds) that an MDB instance can remain
idle in the pool. When an MDB has exceeded the configured timeout, a timer
thread removes the unused MDB. This property defines the interval at which this
thread runs.
A value greater than 0 indicates that the container removes or destroys any MDB
instance that is idle at this specified duration. A value of 0 (zero) specifies that idle
MDB instances can remain in the pool indefinitely.
HL7 Inbound Adapter - Sequence Number Protocol
The following table lists and describes the property that appears on the Sequence Number
Protocol page of the Properties Editor accessed from the Environment. Sequence numbering
helps prevent duplication of data.
