ARB_SUPPORT is a system parameter that controls the Access Rights Block (ARB) compatibility option on Alpha and Integrity servers, is provided specifically to support products that have not yet been updated to use the new per-thread security Persona Security Block (PSB) data structure instead of the ARB. Changing the value of ARB_SUPPORT from 2 or 3 (the default) to any other value can affect the operation of these products.

VSI recommends that all Version 7.3-1 systems have the ARB_SUPPORT parameter set to 3 (the default). Do not change the ARB_SUPPORT parameter to any other value until all products dependent on the ARB and associated structures have been modified for the new environment.
