The following procedure outlines the main steps of upgrading a SLES 10 TASM-licensed system to a SLES 11 system licensed for TASM or IWM. Before performing this task, be sure to review General Upgrade Considerations and License- and Platform-Dependent Upgrade Considerations.
- Ensure that the Teradata Database version on the system is supported on SLES 11 and meets the requirements for workload migration based on whether you plan to use the Pre-Migration Tool.
- If your system includes rule sets that you have not used and do not intend to use in the future, delete them to speed the process of workload migration.
-
[Optional] To refine the otherwise automatic results of converting workloads for use in SLES 11, use the Pre-Migration Tool well in advance of the operating system upgrade.
If you do not use the tool, or if you accept all default settings when using the tool, workloads as automatically migrated may not meet your priority-scheduling goals in SLES 11.
- Back up the TDWM database. This database encompasses the tdwm.premigrate table, which contains any adjustments to workloads that resulted from use of the Pre-Migration Tool.
- Upgrade from SLES 10 to SLES 11.
- Run the TDWMDIP program. The TDWMDIP program converts SLES 10 workloads or performance groups to SLES 11-compatible workloads based on a default processing scheme or the directives in the tdwm.premigrate table within the TDWM database, if such directives exist.
- Bring the system to the Logons Enabled state.
- Use the Workload Designer portlet in Teradata Viewpoint to refine workload settings as necessary.
