Catalog Store Cache Size

Use the -c switch to set the amount of memory in the cache for the catalog store.

The start_iq command, and the iqdemo.cfg and default.cfg configuration files set the -c parameter to 48MB on 64-bit systems and 32MB on 32-bit systems.

Any cache size smaller than 10000 is assumed to be in KB (1K =1024 bytes); any cache size 10000 or greater is assumed to be in bytes. You can also specify the cache size as nK or nM.

If you start the server without using start_iq, iqdemo.cfg, or default.cfg, the default initial cache size is computed based on the amount of physical memory, the operating system, and the size of the database files. The database server takes additional cache for the catalog when the available cache is exhausted.

Warning! To control catalog store cache size, you must do either of the following, but not both, in your configuration file (.cfg) or on the UNIX command line for server startup:

Set the -c parameter, or,
Set specific upper and lower limits for the catalog store cache size using the -cl and -ch parameters

Do not specify other combinations of these parameters.

The cache size for the IQ store does not rely on the catalog cache size.
