Chapter 5 HPSS Infrastructure Configuration236 September 2002 HPSS Installation GuideRelease 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 serverconnections* 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****************************************************************************/{ “HPSS_SM_SRV_CONNECT_FAIL_COUNT”,“3”},{ “HPSS_SM_SRV_CONNECT_INTERVAL_MIN”,“20”},{ “HPSS_SM_SRV_CONNECT_INTERVAL_MAX”,“60”},{ “HPSS_SM_SRV_LIST_UPDATE_INTERVAL”,“5”},{ “HPSS_SM_SRV_MONITOR_THREADS”,“10”},{ “ENCINA_TPOOL_SIZE”, “100” },/***************************************************************************** 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
