Step
| Description
|
---|---|
New segment internal task
| Required. Internal task that prepares the job to run.
|
Create audit snapshot - before
| Creates a snapshot of the state of the objects, such as indexes and triggers, that belong to the segmentation group before the ILM Engine moves any data.
|
Create optimization indexes
| Creates optimization indexes to improve smart partitioning performance. Indexes are used during the segment data step to generate the selection statements that create segments. This step is applicable only if you have defined optimization indexes in the Enterprise Data Manager.
|
Disable access policy
| Disables the access policy on the default segment.
|
Create new segments
| Required. Creates the table spaces, grants required schema access, and creates the segments.
|
Split single segment to multi segments
| Required. Moves data to the new segment.
|
Drop optimization indexes
| Drops any optimization indexes you created in the Enterprise Data Manager.
|
Create audit snapshot - after
| Creates a snapshot of the state of the objects, such as indexes and triggers, that belong to the segmentation group after the ILM Engine moves the data into the segments.
|
Compare audit snapshots - summary
| Compares and summarizes the before and after audit snapshots.
|
Compile invalid objects
| Compiles any not valid objects, such as stored procedures and views, that remain after the ILM Engine creates segments.
|
Enable access policy
| Enables the access policies you applied to the segmentation group.
|
Collect segmentation group statistics
| Collects database statistics, such as row count and size, for the segmentation group.
|
Clean up after segmentation
| Cleans up temporary objects, such as tables and indexes, that are no longer valid after segment creation.
