If you omit 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
The server computes the 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:
-
25% of the physical memory of
the machine, or,
-
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.
