VIOC (VCC) Cache Limits?

» close window

The Question is:

 
Setting VCC_MAXSIZE Parameter to Maximum value..
 
Hi,
 We have AlphaOpenVMS system. We  tried to set VCC_MAXSIZE
parameter to Max value given. Wa have 4GB RAM and VCC_FLAGS is set
to 1.
 
 When we reboot it says system pagetable full and does not set this
parameter.  How to increase this size ?Can anybody help us to set this
parameter to max value for better performance?
 
Thx in advance

The Answer is :

 
  Do NOT use SYSGEN for this or other direct parameter manipulations,
  use MODPARAMS.DAT and AUTOGEN.  Direct manipulation of system parameters
  can be risky practice at best, and particularly given that AUTOGEN knows
  and manages the various parameter inter-relationships.
 
  That said, the VIOC (VCC) is currently limited to the capacity of the
  32-bit system space -- the replacement caching support planned for an
  upcoming OpenVMS release removes caching limits -- including this one.
