DD_HASHMAX configuration parameter

Use the DD_HASHMAX configuration parameter to specify the maximum number of tables in each hash bucket in the data-dictionary cache.

A hash bucket is the unit of storage (typically a page) whose address is computed by the hash function. A hash bucket contains several records.

For example, if the DD_HASHMAX configuration parameter is set to 10 and the DD_HASHSIZE configuration parameter is set to 59, you can store information about 590 tables in the data-dictionary cache, and each hash bucket can have a maximum of 10 tables.

Use a text editor to modify the configuration file.
