Purpose
The config_systems command configures the DSC settings for the Teradata system used for backup and restore jobs. It also sets the selector in the targeted system for ActiveMQ and establishes a JDBC connection to the target system. Nodes are configured automatically after restarting DSMain on the system.
Syntax
config_systems -f|-file File -s|skip_system_config SkipSystemConfiguration
Example
dsc config_systems -f configSystem.xml -s system
Parameters
- f|file filename
- The full path and name of the file containing the necessary configuration parameters.
- s|skip_system_config SkipSystemConfiguration
- [Optional] Flag indicating whether the systems and node configuration or selector setting is skipped when you run the command. If this option is not specified, then both parts of the configuration (system and selector) are run. Enter one of the following:
- system: Avoid configuring Teradata systems and nodes
- selector: Avoid setting the selector in the targeted system for ActiveMQIf you choose the selector option, restart the DSMAIN on the database.
- u|user_authentication User
- Required when security management is enabled. Supplies the command with the Viewpoint user, and triggers a password prompt for authentication.
Permissions required: Administrator role
Usage Notes
System nodes are configured by auto discovery.

Component names | The component name can only use the following characters: 'A-Z', 'a-z', '0-9' and '_'. |
The first character of the component name cannot be '_'. | |
Allowing Backing Jobs Based on Full or Cumulative Backup Jobs Completed with Errors | By setting the skip_force_full option in the XML file, you can run a CBB backup job that is based on a prior full or cumulative backup job that completed with errors.
|
The skip_force_full option is set system-wide. You cannot use this option on a single-job basis. | |
System Configuration Attributes | The following XML file example shows system configuration attributes. System configuration is subject to the following restrictions and requirements. |
Setting reset_node_limit to true overwrites node limits with the system's hard and soft limits. | |
Soft and hard limits for insertion of new nodes:
|
|
Soft and hard limits when updating existing nodes:
