Although primary system users receive a space default allocation during initial system setup, you must manually adjust the space for the Crashdumps and DBC users.

System-generated User and Function Perm Space Required
Crashdumps

Temporarily stores PDE memory dumps.

Approximately 1 GB default

For information on allocating crashdumps space, see Assigning Perm Space to the Crashdumps Database.

DBC

Initially owns all usable disk space.

Contains:
  • Data Dictionary tables
  • Views and macros
  • System tables
  • Logs and transient journals
After allocation of space to administrative users, DBC should retain approximately 10% of the total available space to contain system tables.
The space retained by user DBC space is not usable for any other functions.
SysAdmin

Contains tables, views and macros for network-based load jobs.

Do not reuse the name SysAdmin.
Approximately 40 MB default
Sys_Calendar

Contains tables and views for date-related functions.

Approximately 15 MB default
