Using AWS Schema Conversion Tool in an offline mode | Amazon Web Services
This video shows how to use AWS Schema Conversion Tool (AWS SCT) in an offline mode. AWS SCT converts your on-premises database schema and code objects to a format compatible with a target cloud database. When disconnected from your source database, AWS SCT performs such operations as migration assessment and database schema conversion.

5.76 -> - [Narrator] Our customers
use AWS Schema Conversion Tool
8.71 -> to migrate their on-premises
databases to the AWS cloud.
12.9 -> AWS SCT automatically converts
the source database schema
16.98 -> and code objects to a format compatible
19.3 -> with the target database.
21.35 -> After you connect to your source database
23.33 -> and load the source
metadata into your project,
25.84 -> you can use AWS SCT in an offline mode.
29.54 -> When disconnected from
your source database,
31.84 -> you can use AWS SCT to perform
the following operations:
36.6 -> add mapping rules,
37.89 -> create database migration
assessment reports,
40.64 -> convert database schemas and code,
43.16 -> edit your source and converted code,
45.14 -> save your source and converted code
46.94 -> as SQL scripts in a text file.
49.32 -> This video shows how to work with AWS SCT
52.55 -> in an offline mode.
57.89 -> We create a new a AWS SCT project,
62.39 -> add a source Oracle database,
and connect to this database.
73.7 -> In the main view, we
choose two database schemas
75.943 -> that we want to migrate to the AWS cloud.
81.5 -> In the source metadata tree,
83.12 -> we choose the Schemas
node and load metadata
85.43 -> for the selected schemas.
87.66 -> Make sure that you select only the schemas
89.61 -> you need to migrate
because loading metadata
91.99 -> for all database schemes may take hours.
95.35 -> Now, we save the AWS SCT project
98.7 -> and disconnect from the source database.
104.572 -> AWS SCT now works in an offline mode.
111.1 -> We add mapping rules,
112.57 -> which define a target database platform
114.81 -> for every source database schema.
117.13 -> For the Chinook schema,
118.43 -> we choose Amazon Aurora
PostgreSQL-Compatible Edition
121.65 -> as a migration target.
123.25 -> For the LargeDB schema,
125.06 -> we choose Amazon Redshift
as a migration target.
133.13 -> We switch to the main view to create
134.86 -> a database migration assessment report.
137.63 -> This assessment report provides a summary
139.72 -> of your schema conversion
tasks and the details
142.08 -> for items that AWS SCT
can't automatically convert.
146.632 -> AWS SCT uses the loaded metadata
149.24 -> of Chinook and LargeDB schemas,
151.38 -> which is stored in the
project to create this report.
155.39 -> You can see that AWS SCT generated
158.09 -> the database migration assessment report
160.21 -> for Chinook and LargeDB schemas.
166.41 -> Now, we convert these two database schemas
169.07 -> to their respective
target database platforms.
173.65 -> The target metadata tree
now includes schemas
176.03 -> with converted code.
184.84 -> We can edit the database code,
186.7 -> which is stored in the project.
188.52 -> For example, you can see an action item
190.96 -> because AWS SCT can't convert
the selected procedure.
195.32 -> It uses the SYSDATE function,
197.21 -> which returns the date
from the database time zone
199.66 -> instead of your time zone.
201.53 -> We change the SYSDATE
function to CURRENT_DATE
203.88 -> and convert this procedure again.
205.97 -> These changes apply to the code,
207.9 -> which is stored in the AWS SCT project.
211.46 -> Your source database
code remains unchanged.
214.56 -> Now AWS SCT converts the procedure
217.34 -> and doesn't show an action item.
223.167 -> AWS SCT converted the
Chinook database schema
226.27 -> to a format compatible with
Amazon Aurora PostgreSQL.
230.09 -> We save the converted code to a text file.
235.05 -> We can review, edit,
and then apply this code
237.78 -> to the Amazon Aurora PostgreSQL database.
241.76 -> This completes the overview
of the AWS SCT offline mode.
246.3 -> Thanks for watching this video.
