TABLE 52 Environment- HL7 Inbound Adapter -TCPIP Inbound Settings
Name Description
Steady PoolSize An integer indicating the minimum numberof message–driven beans to
maintain. When thevalue is set to a numbergreater than 0 (zero), the container
pre-populates the MDB pool with thespecied number and tries toensure that
there are alwaysthis number of beans in thefree pool. This ensures that thereare
enough MDB beansin the ready-to-serve state toprocess user requests.
This property doesnot necessarily guarantee that no morethan steady-pool-size
instances exist ata given time. It onlygoverns the number of instances thatare
pooled over along period of time. For example, ifan idle stateless session
container has afully-populated pool with a steady-pool-size of10 and 20
concurrent requests arrivefor the MDB component, thecontainer creates 10
additional instances tosatisfy the burst of requests. Theadvantage of this is that it
prevents the containerfrom blocking any of the incomingrequests. However, if
the activity isreduced to 10 or fewer concurrentrequests, the additional 10
instances are discarded.
Max PoolSize An integer indicatingthe maximum number of message–driven beansin the
pool. A valueof 0 (zero) indicates that thepool is unbounded.
Pool IdleTimeout in
Seconds
The maximum amountof time (in seconds) that anMDB instance can remain
idle in thepool. When an MDB hasexceeded the congured timeout, a timer
thread removes theunused MDB. This propertydenes the interval at whichthis
thread runs.
A value greaterthan 0 indicates that the containerremoves or destroys any MDB
instance that isidle at this specied duration. Avalue of 0 (zero) species thatidle
MDB instances canremain in the pool indenitely.
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.
