What is a heap related to database ?

Answer Posted / dhaval kodrani

There is one database heap per database, and the database
manager uses it on behalf of all applications connected to
the database. It contains control block information for
tables, indexes, table spaces, and buffer pools. It also
contains space for the log buffer (logbufsz) and temporary
memory used by utilities. Therefore, the size of the heap
will be dependent on a large number of variables. The
control block information is kept in the heap until all
applications disconnect from the database
