The Sentinel 6.1 Rapid Deployment installation allocates 70% of the free disk space available at the time of installation for database, and the value is specified in the diskSpaceAllocated property of the das_core.xml. If the database consumes more than what is allocated, the Sentinel services might halt. To monitor such incidents, a scheduler job has been created in the Sentinel services. The scheduler job monitors the disk space for threshold. There are two thresholds for the disk space. The value for the lower threshold is 85% and for the upper threshold it is 95% of the disk space allocated.
The scheduler job runs based on the value specified in the dbStatsInterval property of the das_core.xml. When the database/tablespace size reaches the threshold limits, Sentinel 6.1 Rapid Deployment system warns you of the disk space limit and behaves as follows:
Lower Threshold: When database/tablespace size reaches 85% of the disk space allocated, the Sentinel 6.1 Rapid Deployment system warns you with an internal audit event indicating the limit. These are logged as internal audit events with severity 4.
Upper Threshold: When the database/tablespace size reaches 95% of the disk space allocated, Sentinel 6.1 Rapid Deployment system removes the oldest partitions for each partition group until database/tablespace size falls below the threshold level (85%), and also sends an internal audit event for each partition dropped.
NOTE:Sentinel 6.1 Rapid Deployment does not attempt to remove the online current partition.
