Table 2-1 SIP Stack Parameters (continued)
DescriptionParameter Name
Specifies a boolean value that closes the server
socket after a client transaction enters the
TERMINATED state, if
CACHE_CLIENT_CONNECTIONS is set to false.
This enables a client to release buffer threads
and socket connections that are associated with
a client transaction after the transaction
terminates, at the expense of the performance
of the stack. The default value is true.
com.hp.net.javax.sip.CACHE_CLIENT_CONNECTIONS
Specifies concurrency control from the number
of simultaneous active threads. If
THREAD_POOL_SIZE is not specified and the
listener is re-entrant, each event delivered to
the listener is run in the context of a new
thread. If THREAD_POOL_SIZE is specified
and the listener is re-entrant, the stack runs
the listener using a thread from the thread
pool. This enables you to manage the level of
concurrency to a fixed maximum. Threads are
pre-allocated when the stack is instantiated.
If THREAD_POOL_SIZE is specified and the
listener is not re-entrant, the stack uses the
thread pool thread from this pool, to parse and
manage the state machine but runs the listener
in its own thread. The default value is infinity.
com.hp.net.javax.sip.THREAD_POOL_SIZE
Specifies whether the listener is re-entrant. If
the listener is re-entrant, the stack manages a
thread pool and simultaneously calls the
listener from the same thread that reads the
message. Multiple transactions can
concurrently receive messages. As a result,
multiple threads are active in the listener at
the same time. The default value is false.
com.hp.net.javax.sip.REENTRANT_LISTENER
Specifies the maximum number of
simultaneous TCP connections handled by the
stack.
com.hp.net.javax.sip.MAX_CONNECTIONS
Specifies the maximum size of the server
transaction table. The low water mark is 80%
of the high water mark. Requests are
selectively dropped from the low water mark
to the high water mark range. If the server
transaction table is smaller than the low water
mark, requests are unconditionally accepted
by the stack. The default value for the high
water mark is 5000.
