The timeflowPointParameters property supports of variety of types, each representing a specific use case:
TimeflowPointSemantic: Specific semantic point (lastest point or latest snapshot)
TimeflowPointSnapshot: Specific snapshot (identified by its reference)
TimeflowPointLocation: Specific "location" (scn, lsn, transaction id, ...)
TimeflowPointTimestamp: Specific point in time
....
Here is an example of an API call payload rolling back to a snapshot:
{
"type": "OracleRollbackParameters",
"timeflowPointParameters": {
"type": "TimeflowPointSnapshot",
"snapshot": "ORACLE_SNAPSHOT-144"
}
}
In general, using the Delphix CLI (accessible over SSH) makes it easy to discover new capabilities thanks to the integrated help and autocompletion of types.
