TABLE56 Environment- HL7 Outbound Adapter - Connection Pool Settings
Name Description
SteadyPool Size Aninteger indicating the minimum number of resource adapter connections to
bemaintained. When the value is set to a number greater than 0 (zero), the
containerpre-populates the RA connection pool with the specied number and
triesto ensure that there are always this many connections in the free pool. This
ensuresthat there are enough connections in the ready-to-serve state to process
userrequests.
Thisproperty does not necessarily guarantee that no more than steady-pool-size
instancesexist at a given time. It only governs the number of instances that are
pooledover a long period of time. For example, if an idle stateless session
containerhas a fully-populated pool with a steady-pool-size of 10 and 20
concurrentrequests arrive for the resource adapter connection component, the
containercreates 10 additional instances to satisfy the burst of requests. The
advantageof this is that it prevents the container from blocking any of the
incomingrequests. However, if the activity is reduced to 10 or fewer concurrent
requests,the additional 10 instances are discarded.
MaxPool Size Aninteger indicating the maximum number of resource adapter connections in
thepool. A value of 0(zero) indicates that the pool is unbounded.
PoolIdleTimeout in
Seconds
Themaximum amount of time (in seconds) that a resource adapter connection
instancecan remain idle in the pool. When a connection has exceeded the
conguredtimeout, a timer thread removes the unused connection. This
propertydenes the interval at which this thread runs.
Avalue greater than 0 (zero) indicates that the container removes or destroys any
resourceadapter connection instance that is idle at this specied duration. A
valueof 0 (zero) species that idle connections can remain in the pool
indenitely.
