Hello Vinay,
what are you wondering about?
That the database uses 82.3% of the memory?
In MAXDB there exists a parameter called:
CACHE_SIZE (MaxDB < 7.7.03) respectively CacheMemorySize (MaxDB >= 7.7.03)
"The value specifies the i/o capable memory used by different
MaxDB components in particular the data cache, converter and
the shared catalog cache."
When the database starts it allocates the memory given by the parameter. This memory is reserved for the db. It will not become free if there is no activity on the db.
