Configuration Parameters
Vector configuration parameters are stored in these files:
vectorwise.conf
Stores X100 Engine parameters. These parameters must be set by manually editing the file. For more information, see
X100 Engine Configuration.
config.dat
Stores parameters for the other components of the installation.
Note: Do not edit the config.dat file directly. Use Configuration-By-Forms (or its visual equivalent Configuration Manager, if available) to set parameter values.
Some parameters are dependent on, or derived from other parameters.
For instructions on configuring specific parameters, see the online help for Configuration-By-Forms or Configuration Manager.
Setting Parameter and Derived Parameter Values
For most component configurations in config.dat, you can edit the value of a parameter, restore the parameter to a value that has been saved in a configuration "snapshot" file, or restore the parameter to its original installation value.
For instructions on editing and restoring parameter values, see online help.
Using VCDA to Restore Configuration Parameter
Visual Configuration Differences Analyzer (VCDA) can be used to restore configuration parameter values saved in a snapshot file. For detailed steps, see the VCDA online help.
Protecting or Recalculating Derived Parameters
The settings of some configuration parameters are derived from those of other parameters. When a parameter is changed, any parameters derived from that parameter are automatically updated.
Any derived parameter can be set in "protected" mode, which means that the Configuration-By-Forms utility or Configuration Manager cannot recalculate the derived value. Protected mode allows you to set a desired value for the parameter, even though the value is normally derived by the system from other parameters.
If protected mode is disabled, the value of the parameter is adjusted whenever new values are set for other parameters on which the derived value is based. The new and old values are shown in the change log.
For detailed steps on performing these procedures, see the online help.
Components That Use Derived Parameters
The following components contain parameters that are derived from other parameters:
• DBMS Server
• Security
• Locking System
• Logging System
• Recovery Server
