New Features in Plug-in for Teradata v13.0
The following is a list of issues addressed and enhancements implemented in this release of Plug-in for Teradata.
When a specific BAR Server is selected while restoring Data Dictionary or copying Full Clustered Backups to an alternate Teradata DBS, the job status will change to “Waiting for Media” if the requested media is in use or the media request times out.
|Under certain circumstances, the Multi-stream and Clustered (Full Multi-stream, Full Multi-stream Online, Full Clustered and Full Clustered Online Backups) would remain in waiting for media state for 5 minutes before writing the on-tape indices. This issue has been resolved in this release.||TRG-318|
|The redundant part in an inefficient SQL statement for ARC catalog cleanup has now been removed.||TRG-319|
|Internally the Run Job on Client list is now set to the <AUTO> option when restoring Full Clustered and Full Clustered Online savesets generated with plug-in versions prior to v12.0.||TRG-322|
|The Force Release Lock on Abort option can now also be selected for the Data Dictionary backup jobs.||TRG-323|
|Previously, the plug-in obtained the Teradata Database Version parameter from the local plug-in where job was running. This issue has been resolved in this release. The plug-in now obtains this parameter from the master plug-in, regardless of where backup job is running.||TRG-325|
|The plug-in now allows multiple ARC options in Override ARC Options on the Backup and Restore Options tabs.||TRG-330|
|Users now can select the system tables node in the Backup Selection Tree (<All DBC Objects> in Hierarchical View and DBC in Classical View) for a user script backup.||TRG-331|
The following is a list of issues known to exist at the time of the Plug-in for Teradata v13.0 release.
A clustered backup job using the Ensure This Backup Is The First On Media and Media Availability Check Timeout options will hang if the job does not have sufficient media.
|When the Media Availability Check Timeout option is not selected, media requests for all streams are done in parallel. If this option is selected, the media checks are done serially, presenting a window of time for media to be assigned to another stream. This results in media being moved from one drive to another. For multi-stream backups, the reassignment or movement of media may cause ARC Server timeout to expire resulting in a failed job. For cluster backups, this may cause a significant delay in the start of the job.||TRG-301
|While performing backups, ARC does
not allow you to exclude the following objects that do not contain any
The Plug-in for Teradata does not perform this check. A backup job with such exclusions will still backup the excluded objects and complete with warnings. These objects will appear on the Selections tab of the NVBU Restore window as excluded objects, which means that they cannot be restored individually.
|If two or more tables in a database use different journal tables, a database-level restore cannot be performed. Instead, you must restore the individual tables. This is an ARC limitation, and applies to Full On-line, Full Clustered On-line and Incremental backup savesets which contain journal backups.|
|If a journal table does not reside in the same target database as the data tables, do not select the journal database during restore. Instead, select the target database or the individual data tables. This applies to Full On-line and Full Clustered On-line backup savesets.|
|The PPI expressions for database tables in a selection set are not displayed when the selection set is modified and you use the Right-click+Open method. Double-click the database node instead.|
|If the PPI expression is modified during restore, then you cannot undo the edits and reverse the changes. However, you can copy the original expression or refresh the NVBU Restore window to retrieve the original expression used to backup the partition.|
|If a cluster job fails and the Teradata Master Plug-in process stops immediately (either because Retry Failed Clusters on Another Remaining Client option is not selected for the job, or no more clients are available) before the monitor process could poll the latest job status, then status of the last job under Performance Data will continue displaying InProgress while the correct status will be displayed under Job Information.|
