NetBase Shadowing
5-5
Configuration Parameters
The operation of NetBase, including its various features, is defined by NetBase's configuration
parameters. Configuration maintenance is a subsystem of the NetBase control program, NBCTRL.
The configuration parameters can be displayed and modified using the configuration subsystem.
The systems manager should become familiar with the control program, the configuration
parameters, and the configuration maintenance commands in order to set up the shadowing facility.
Effective with version 9.6, shadow records are automatically added to the directory if the following
conditions are met:
• The directory is large enough to hold all the records
• A shadow record with wildcards exists for the shadowed file
Note. Although shadow records for IMAGE databases may be auto-added, they will not
work. This is because the password must be included in the shadow records for the
database to be opened without password violations.
The parameters used in shadowing can be listed in the configuration maintenance program by
entering the following commands. Normally, the default for these parameters is sufficient. If you
suspect a problem with shadowing or want to change these parameters, please contact the Technical
Support group before making any changes.
