Chapter 5 HPSS Infrastructure Configuration
236 September 2002 HPSS Installation Guide
Release 4.5, Revision 2
***************************************************************************
* System Manager Specific
*
* The SM attempts to throttle the connection attempts to other servers. It
* will attempt to reconnect to each server every
* HPSS_SM_SRV_CONNECT_INTERVAL_MIN seconds until the number of failures for
* that server has reached HPSS_SM_SRV_CONNECT_FAIL_COUNT. After the failure
* count has been reached the SM will only try to reconnect to the server
* every HPSS_SM_SRV_CONNECT_INTERVAL_MAX seconds until a successful i
* connection is made at which time the connection interval for the server
* will be set back to HPSS_SM_SRV_CONNECT_INTERVAL_MIN.
*
* HPSS_SM_SRV_CONNECT_FAIL_COUNT- Number of connection failures to a
* server before the
* HPSS_SM_SRV_CONNECT_INTERVAL_MAX
* interval takes affect
* HPSS_SM_SRV_CONNECT_INTERVAL_MIN - Interval between attempting server
* connections when
* HPSS_SM_SERVER_CONNECT_FAIL_COUNT
* has not yet been reached (seconds)
* HPSS_SM_SRV_CONNECT_INTERVAL_MAX - Interval between server
connections
* when HPSS_SM_SERVER_CONNECT_FAIL_COUNT
* has been reached without a successful
* connection (seconds)
*
* HPSS_SM_SRV_LIST_UPDATE_INTERVAL - Frequency at which the SM sends
* updated server lists to the Data
* Server so that we don’t flood the
* Data Server with updates (seconds)
* HPSS_SM_SRV_MONITOR_THREADS- Number of threads created to monitor
* server connections
* ENCINA_TPOOL_SIZE - Thread Pool Size used by the System
* Manager

***************************************************************************
* The HPSS_NOTIFY_Q_*_THREADS variables define how many threads the SSM
* System Manager will create per client to process that queue. Each thread
* will take notifications one at a time from the queue and forward them to
* its client. The recommended number of threads per client per queue is 1.
* Too many threads per client per queue will cause unnecessary memory growth
* in the SSM System Manager.
*
* HPSS_NOTIFY_Q_DATA_THREADS - Number of threads to create per client
* to process the queue of notifications of
* managed object attribute changes
* HPSS_NOTIFY_Q_LIST_THREADS - Number of threads to create per client
* to process the queue of notifications of
* changes to the server list, drive list,
* class of service list, storage class
* list, hierarchy list, migration policy
* list, or purge policy list
