If you do not provide a value for the start_iq server
option -c switch (either on the command line
or using the start_iq default), the
database server computes the initial catalog store cache allocation
as follows:
The database server uses 32MB as the
minimum default cache size.
The database server computes a runtime-specific
minimum default cache size, which is the lesser of the following
items:
25% of the physical memory
of the machine.
The sum of the sizes of the main database files
specified on the command line. Additional dbspaces apart from the
main database files are not included in the calculation. If no files
are specified, this value is zero.
The database server allocates the greater of the
two values computed.
