Info

To determine whether storage reclamation will be beneficial after one of these operations, it is important to consider the effect of the reserve maintained by ASRU when the utility reduces the size of the disk group during the compaction phase. The temporarily reduced size is equal to the allocated space plus a reserve which allows active databases to grow during the reclamation process; the default reserve is 25% of the allocated storage. Storage reclamation is likely to be beneficial if the amount of allocated physical storage significantly exceeds the amount of storage allocated within ASM plus the reserve. cli% showvv - showcols \ © Copyright 2011 Hewlett-Packard Development Company, L.P.
