These columns represent the amount of memory resident specific to virtual processor activities, subdivided into memory types. The columns do not include any memory allocations specific to the node the vproc is running under.

Disk memory segments can be in one of four states:

  • Clean (unmodified) and Unaccessed by any process (CU)
  • Dirty (modified) and Unaccessed (DU)
  • Clean and Accessed (CA)
  • Dirty and Accessed (DA)

Permanent segments for an entire table can be user-locked-in to memory. These are called frozen segments (Frz), and no state subdivision is necessary because they cannot be aged or forced out of memory.
