To restore the SystemFE database from an earlier release, you must first clean up macros that are no longer meaningful to the current system. After cleaning up the obsolete macros, you need to recreate the SystemFE.diskevents macro.
DIP must have already been run once to ensure that the supporting infrastructure is updated (for example, empty macros or views should already have been created). If DIP has been run at least once previously, run the appropriate DIP again to recreate the macro.
- DIPSYSFE - creates the macro if it is NOT already present
- DIPPOST - creates Teradata session mode CDS macros if they are NOT already present
- DIPANSI - creates ANSI session mode CDS macros if they are NOT already present
- DIPPATCH - fills in for any release-dependent changes
For more information on these DIP files, see Teradata Vantage™ - Database Utilities, B035-1102.
