User Guide
You can select and define job options for backup, restore, and analyze jobs by specifying the values for the options in the XML file containing the job definition.
The XML files in the sample library and the files produced by the BAR Operations portlet have the XML in a specific order. For the jobs to run correctly, do not change the order of the XML within the files.
The following options are for Teradata only.
Job Options Description Job Type
online Determines the type of backup to perform.
Default. Backs up everything associated with each specified object while the database is offline. No updates can be made to the objects during the backup job run.
Backs up everything associated with each specified object and initiates an online archive for all objects being archived. The online archive creates a log that contains all changes to the objects while the archive is prepared.
  • Backup
dataphase Determines the type of backup to perform.
Default. Performs a full backup.
Performs a dictionary-only backup.
  • Backup
enable_temperature_override Optional setting that pertains to restore jobs only.
The temperature_override value is applied when restoring the data.
The temperature from the backup is applied.
  • Restore
nosync Determines where synchronization is done for the job. Only available for online backup jobs.
  • Default value is false. If false, synchronization occurs across all tables simultaneously. If you try to run a job that includes objects that are already being logged, the job aborts.
  • True allows different synchronization points. If you try to run a job that includes objects that are already being logged, the job runs to completion and a warning is returned.
  • Backup
Determines the types of messages that the database job logs.
Default. Enables minimal logging. Provides only error messages.
Adds warning messages to error message logging.
Provides informational messages with warning and error messages to the job log.
Enables full logging. All messages, including Debug, are sent to the job log.
  • Backup
  • Restore
nowait Generates warning messages to the job status log for objects that the Teradata Database fails to get locks on immediately.
In either case, the job waits until the lock is released.
  • Default is true. If true, a warning message is generated when a job is stopped because of a lock.
  • If false, no warning message is generated when a job is stopped because of a lock.
  • Backup
  • Restore
reblock Determines level of inserts, either row or block level. This option is valid only for the same configuration restore. Different configuration restore always use row level inserts.
  • Default is false. The restore uses block level inserts.
  • If true, the restore uses row level inserts, forcing reblocking when tables must be restored matching the target system's default block size. Required when the backup is restored to a different AMP configuration, hash function, hash bucket, row format or block alignment. Optional when the backup is restored from a system with different block size than the target system and the block size of the restored data objects must match the target system's block size.
  • Restore
Allows tagging of sessions or transactions with a set of user-defined name-value pairs to identify where a query originated. These identifiers are in addition to the current set of session identification fields, such as user ID, account string, client ID, and application name.
Valid query band values are defined on the database.
  • Backup
  • Restore
Determines the temperature at which data is restored.
Default. This data is restored at the default temperature setting for the system.
This data is accessed frequently.
This data is accessed less frequently.
This data is accessed least frequently.
  • Restore
Defines data compression used.
Default. Applies same data compression as the backup job if allowed on the target system.
Compress data at the block level if allowed on the target system.
Restore the data blocks uncompressed.
  • Restore
disable_fallback Fallback protection means that a copy of every table row is maintained on a different AMP in the configuration. Fallback-protected tables are always fully accessible and are automatically recovered by the system.
Default is false. Must be entered in lowercase letters.
The disable_fallback option only takes effect when the run_as_copy value is true.
  • Restore
run_as_copy Allows restore to run as a copy.
  • Default value is false.
  • If true, the restore runs as a copy.
