MV2OCI – One-Click Move of your Data into Oracle Cloud Infrastructure Database

mv2oci is a tool which helps to migrate on-premise data to the Oracle Cloud Infrastructure based on Oracle Data Pump and works as a data load tool. The local Data Pump export is transferred and imported to/on the target cloud server automatically. There is no use of Oracle Cloud Object Storage, the dump files are transferred with rsync or scp to the target database node. This is the different behavior to mv2adb – see my blogpost here – which uses the Object Storage. As an option, the data can be transferred via Database Link (mv2oci Parameter –netlink).

All you need to know about mv2oci is written in the My Oracle Support Note (OCI) MV2OCI: move data to Oracle Cloud Database in “one-click” (Doc ID 2514026.1).  The newest version of the rpm package can be downloaded there. The package has to be installed on the source server.


  • SQL*Net connection between the two databases
  • A Java executable – in my case I have installed jre (yum install jre)
  • Verify if the firewall to the VCN Subnet is open for Port 1521 – Port 22 is open as per default
  • Password of database user SYSTEM

The Use Case

Let’s move the database schema SOE from my on-premise Oracle Linux Server into the cloud step-by-step. An Oracle Cloud Infrastructure database instance is already up and running, the target tablespace is created. The data centers are connect by VPN.


Database Information

Source Target
CDB Name CDB118 CDB118
PDB Name pdb11801 pdboci
Hostname heckenweg srv-cdb118
IP Address
PDB Service Name

1. Package Installation

Download and transfer the package to the on-premise server, for example in directory /tmp. As user root, install the package.

Verify that the SSH private key which is used for the connection to the Oracle Cloud Infrastructure server is available and the connection is working. Here is the OCI SSH key available in the $HOME/.ssh.

2. Encrypt the SYSTEM passwords for both databases – mv2oci encpass

3. Configuration File

A template of the configuration file is located in /opt/mv2oci/oci. I used the following parameters – other parameters like ICHOME for Instance Client configuration are well described.

Source DB Parameters

Parameter Value
DB_CONSTRING //heckenweg/
DUMP_FILES /tmp/exp_soe_18102020_01.dmp, /tmp/exp_soe_18102020_02.dmp
OHOME /u01/app/oracle/product/19.0.0/dbhome_1

Expdp/Impdp Parameters

Parameter Value
Dump Name exp_soe_18102020.dmp
PARALLEL 2 – creates two Dumpfiles called exp_soe_18102020_01.dmp and exp_soe_18102020_02.dmp

OCI Parameters

Parameter Value
OC_SSHKEY /home/oracle/.ssh/id_rsa_oci_29012020
OC_DB_PASSWORD Encrypted SYSTEM password


4. Export Data – mv2oci expdp

Dump files created in /tmp.

5. Transfer Data – mv2oci putdump

Files are available now on target server.

6. Import Data

Tablespace SOEDATA exists on target server, otherwise you can use to the EXTRA_IMPDP parameters in the mv2oci configuration file to do a remapping etc.

Analysis of the error in the SQL*Developer – there is a missing execution permission on package DBMS_LOCK.

This is an easy thing:

7. Reporting – mv2oci report

The report compares the objects on source and target database.

8.  All in One – mvoci auto

We did the steps one-by-one, by using the parameter auto, the steps above are done automatically (except reporting).

9. Logfiles

Logfiles tom the mv2oci actions are located in:

mv2oci /opt/mv2oci/out/log
Data Pump Directory in parameter DUMP_PATH


mv2oci is another great tool to support the movement to Oracle Cloud Infrastructure. Easy to configure, easy to use. #ilike
