Run Configuration-By-Forms (CBF) and initially configure the Ingres installation. Use the rundbms.opt and showrcp information from Ingres 6.4 as a guideline. For information about CBF and the various tuning parameters, see the System Administrator Guide.

Information on the correlation between 6.4 and Ingres parameter names, is described in Corresponding Parameter Names (see page Corresponding Parameter Names).

Derived parameters are recalculated when values they depend on are changed. If derived parameters are set, they can be “protected” against change.

Ingres versions from 2.0 through 2.6 may calculate very large default lock and resource limits parameters. Check the lock_limit and resource_limit settings, and consider reducing these limits to the Ingres 6.4 settings.

On OS-thread platforms, do not turn on async_io; and do not declare the II_NUM_SLAVES Ingres variable.

Ingres supports larger qef_sort_mem values than Ingres 6.4. Ingres may not need as much qsf_memory as did Ingres 6.4. OS-thread platforms should not reduce quantum_size, as it does not improve performance on those platforms.
