There is a new Oracle Cloud Infrastructure tool available called MV2ADB – (ADB) MV2ADB: move data to Autonomous Database in “one-click” (Doc ID 2463574.1). All steps which have to be executed manually to transfer data into an Autonomous Database are now automated:
- Advisor for local schemas
- Oracle Data Pump local export
- Transfer into Oracle Cloud Infrastructure Object Store
- Create Autonomous Database Credentials to get access on the Object Store
- Oracle Data Pump local import
- Verify Oracle Data Pump import logfile
The data transfer job can be done fully automated or step by step (autonomus schema advisor, export data, create bucket, upload dump files etc.). In this blog post I describe the manual steps.
How it works
Image from My Oracle Support Note 2463574.1:
Prerequisites
- mv2adb rpm package installed, always download the newest version from My Oracle Support (Doc ID 2463574.1)
- HTTP/SQL*Net Connectivity from the on premises server to the Autonomous Database
- Autonomous Database Wallet (can be downloaded from the ATP main page)
- Instant Client with Basic Package, SQL*Plus Package and Data Pump, SQL*Loader and Workload Replay Client – if there is an existing RDBMS installation 18.3 or higher, you can use it
- Java executable – same like above, you can use the RDBMS installation too
- Perl Release 5.10 or above
- Optional: Oracle OCI Command Line Interface – https://docs.cloud.oracle.com/iaas/Content/API/Concepts/cliconcepts.htm installed and configured

Configuration File
The mv2adb install process provides an example of a configuration file – here is my version with OCI CLI enabled. Take care and read the example and the comments. At this point, thanks to Ruggero Citton from Oracle’s Cloud Innovation and Solution Engineering Team for his great support to find my configuration mistake. If you dont’ want to use the configuration file, all parameters can be attached to the mv2db command.
All passwords have to be encrypted with the mv2adb encpass command ind advance.
|
|
# ./mv2adb encpass Please enter the password : Please re-enter the password : |
For the parameter OCI_PASSWORD, you have to create an OCI Authentification Token first in the console or by CLI and encrypt the provided password.
In this configuration file, I use the OCI CLI. In this example we transfer the Oracle demo schema HR. Take care about the Expdp/Impdp Parameters, if you want to encrypt the Data Pump export files, you need an additional Advanced Security Option ASO. No license? Just comment it out or let the parameters blank.

Let’s go – we transfer the local HR Schema to ADB
18/12/2019: At the moment I have some trouble with the automated function which is doing all steps at one (option auto) – this is under investigation.
0. Advisor
It executes the ADB Schema Advisor. This advisor provides information if your data can be transferred into the cloud and which database objects are problematic. If you want to know more, take a look at this My Oracle Support Note: Oracle Autonomous Database Schema Advisor (Doc ID 2462677.1). Excerpt from the output with the hint that user defined tablespaces are not allowed in an ADB environment (If you want to verify it: The manually executed CREATE TABLESPACE command results into ORA-01031: insufficient privileges).
In the background, a temporary user called ADB_ADVISOR is created to analyse the data (Script @/opt/mv2adb/utils/install_adb_advisor.sql). The user will be dropped automatically after the run.

X. Troubleshooting
Logs for all steps are available in the installation sub folder. There you can find all excuted commands, detailed error messages.

My ToDo List for next MV2ADB Blog Post
- Clarification of the license situation, if the export to the cloud has to be encrypted, Advanced Security Option is required, maybe a special license solution like compression for the OCI backup service is planned.
- Execution of steps without a parameter file.
- Transfer data without OCI CLI pre-installed.
Summary
The Oracle Cloud Infrastructure MV2ADB is a great tool to make data moves into the OCI Autonomous Database much easier. I like the concept, a small configuration file, passwords are all encrypted and the logs are very detailed. The advisor is helpful to identify conflict in advance.
