Introd u ction
§ TSAMP can be used to monitor an application’s resources, and automate the
starting, stopping, and failover of resources – it will attempt to maintain a desired
operational state.
§DB2 provides a utility called ‘db2haicu’ that is used to define the domain and
automation policy within TSAMP:
4The automation policy is the set of definitions of all resources, resource groups, and the relationships between them.
4The resource definitions contain attributes that define which start, stop and monitor script (the automation scripts) to
use for a particular resource.
§ The db2haicu utility offers the ability to configure DB2 to failover to a secondary
redundant system in the event of a planned/unplanned outage. Referred to as an
active-passive configuration.
§ DB2 provides a set of scripts which allow TSAMP to control the DB2 resources.
4Scripts that are used by TSAMP to start, stop and monitor DB2 resources – this is the primary link between the two
products
4The mountV105_monitor.ksh, mountV105_stop.ksh and mountV105_start.ksh scripts are used to control the
IBM.Application mount resources.
