IBM HPSS manual Key SM Environment Variables

values may need to be overridden in env.conf.

Key SM Environment Variables

Variable	Default	Functionality
	Value
HPSS_SM_SRV_CONNECT_FAIL_COUNT		Connection Fail Count: number of
		connection failures to a server before the
	3	Max Connection Interval takes affect (*)
HPSS_SM_SRV_CONNECT_INTERVAL_MI		Interval between attempting server
N		connections when Connection Fail
		Count has not yet been reached
	20	(seconds) (*)
HPSS_SM_SRV_CONNECT_INTERVAL_MA		Max Connection Interval: interval
X		between server connections when
		Connection Fail Count has been reached
		without a successful connection
	60	(seconds) (*)
HPSS_SM_SRV_MONITOR_THREADS		Number of threads created to monitor
	5	server connections
HPSS_SM_SRV_QUEUE_SIZE		Request Queue Size used by the System
		Manager server interface - default of 5
		slots in the server interface request
		queue to be used when the server
		interface thread pool is completely full.
		The queue is used to hold RPC requests
		from servers until a thread is available to
		process the request.
		Note that if the request queue has any
		entries in it, it means that all the threads
		in the server thread pool are busy and
		the SM response will be degraded. If
		this happens then it would be good to
		increase the number of threads available
		to the server interface using the
		HPSS_SM_SRV_TPOOL_SIZE
		variable. Increasing the size of the
	5	queue will not help with performance.
HPSS_SM_SRV_TPOOL_SIZE		Thread Pool Size used by the System
		Manager server interface. If the Thread
		Pool is exhausted then server RPC
		requests will be queued in the server
		RPC Request Queue to wait for a thread
		to become available. When the thread
		pool is exhausted SM performance may
		be degraded. Increase this value if that is
		the case. Typically 1 thread per HPSS
		server should be adequate. But a few
	100	extra wouldn't hurt.
