Learn ODA on Oracle Cloud

You want to learn and practice your ODA command line and GUI without having an ODA at home? It should be possible to run the ODA image on VirtualBox but that’s probably a hard work as it is tied to the hardware. About the configuration, you can run the Oracle Appliance Manager Configurator on your laptop but I think it is not compatible with the latest odacli. However, for a long time Oracle provides an ODA simulator and it is now available in the Oracle Cloud Marketplace for free.

Here is it page:

You can get there by: Oracle Cloud Console > Create Compute Instance > Edit > Change Image > Oracle Images > Oracle Database Appliance (ODA) Simulator

I mentioned that this is for free. The marketplace does not allow me to run on an Always Free Eligible shape. But you may take the software and run it elsewhere (you will see the .tar.gz in the opc user home directory)

Cleanup and pull images

From the marketplace, the container is already running but I clean it and re-install. This does everything: it installs docker if not already there (you run all this as root).

# cleanup (incl. portainer)
sudo docker rm -f portainer ; sudo docker rmi -f portainer/portainer
yes | sudo ~/simulator*/
# setup (get images and start portainer)
sudo ~/simulator*/

With this you can connect by http on port 9000 to the Portainer. Of course, you need to open this in the Network Security Groups (I opened the range 9000-9100 as I’ll use those ports later). You can connect with user admin password welcome1… yes, that’s the CHANGE_ON_INSTALL password for ODA 😉

Choose Local repository and connect and you will se the users and containers created.

Create ODA simulators

sudo ~/simulator*/ -d class01 -t ha -n 2 -p 9004 \
 -i $(oci-public-ip | awk '/Primary public IP:/{print $NF}')

the -d option is a “department name”. You can put whatever you like and you can use it to create multiple classes.
-n is the number of simulators (one per participant in your class for example).
-t is ‘ha’ to create two docker containers to simulate a 2 nodes ODA HA or ‘single’ to simulate a one node ODA-lite.
The default starting port is 7094 but I start at 9004 as I opened the 9000-9100 range.

This has created the containers, storage and starts the ODA software: Zookeeper, DCS agent, DCS controller. You can see them from the Portainer console. It also creates users (the username is displayed, the password is welcome1) in portainer in the “odasimusers” team.

From the container list you have an icon ( >_ ) to go to a command line console (which is also displayed in the output (“ODA cli access”) so that you can give it to your students. One for each node when you chose HA of course. It also displays the url to the ODA Console (“Browser User Interface”) at https://<public ip>:<displayed port>/mgmt/index.html for witch the user is “oda-admin” and the password must be changed at first connect.

Here is an example with mine:

ODA Simulator system info:
Executed on: 2021_02_03_09_39_AM
Executed by:

ODA Simulator management GUI:
Username: admin Password: welcome1
num=          5
dept=       class01

Username: class01-1-node0  Password:welcome1
Container : class01-1-node0
ODA Console:
ODA cli access:

Those are my real IP addresses and those ports are opened so you can play with it if it is still up when you read it… it’s a lab.

The Portainer web shell is a possibility but you can go to the Portainer console from the machine where you have created all that you can:

[[email protected] simulator_19.]$ ./ -n class01-1-node0
[[email protected] /]#

Of course you can also simply `sudo docker exec -i -t class01-1-node0 /bin/bash` – there’s nothing magic here. And then you can play with odacli:

[[email protected] /]# odacli configure-firstnet

bonding interface is:

Select the Interface to configure the network on () [btbond1]:

INFO: Restarting the DCS agent
initdcsagent stop/waiting
initdcsagent start/running, process 20423

This is just a simulator, not a virtualized ODA, you need to use this address on node0 and on node 1

Some fake versions of the ODA software is there:

[[email protected] /]# ls opt/oracle/dcs/patchfiles/

On real ODA you download it from My Oracle Support but here the simulator will accept those to update the ODA repository:

odacli update-repository -f /opt/oracle/dcs/patchfiles/
odacli update-repository -f /opt/oracle/dcs/patchfiles/

You can also go to the web console where, at the first connection, you change the password to connect as oda-admin.

[[email protected] opt]# odacli-adm set-credential -u oda-admin
User password: #HappyNewYear#2021
Confirm user password: #HappyNewYear#2021
[[email protected] opt]#

Voila I shared my password for 😉
You can also try the next even ports (9007, 9009…9021) and change the password yourself – I’ll leave this machine for a few days after publishing.

And then deploy the database. Here is my oda.json configuration that you can put in a file and load if you want a quick creation without typing:

{ "instance": { "instanceBaseName": "oda-c", "dbEdition": "EE", "objectStoreCredentials": null, "name": "oda", "systemPassword": null, "timeZone": "Europe/Zurich", "domainName": "", "dnsServers": [ "" ], "ntpServers": [], "isRoleSeparated": true, "osUserGroup": { "users": [ { "userName": "oracle", "userRole": "oracleUser", "userId": 1001 }, { "userName": "grid", "userRole": "gridUser", "userId": 1000 } ], "groups": [ { "groupName": "oinstall", "groupRole": "oinstall", "groupId": 1001 }, { "groupName": "dbaoper", "groupRole": "dbaoper", "groupId": 1002 }, { "groupName": "dba", "groupRole": "dba", "groupId": 1003 }, { "groupName": "asmadmin", "groupRole": "asmadmin", "groupId": 1004 }, { "groupName": "asmoper", "groupRole": "asmoper", "groupId": 1005 }, { "groupName": "asmdba", "groupRole": "asmdba", "groupId": 1006 } ] } }, "nodes": [ { "nodeNumber": "0", "nodeName": "GENEVA0", "network": [ { "ipAddress": "", "subNetMask": "", "gateway": "", "nicName": "btbond1", "networkType": [ "Public" ], "isDefaultNetwork": true } ] }, { "nodeNumber": "1", "nodeName": "GENEVA1", "network": [ { "ipAddress": "", "subNetMask": "", "gateway": "", "nicName": "btbond1", "networkType": [ "Public" ], "isDefaultNetwork": true } ] } ], "grid": { "vip": [ { "nodeNumber": "0", "vipName": "GENEVA0-vip", "ipAddress": "" }, { "nodeNumber": "1", "vipName": "GENEVA1-vip", "ipAddress": "" } ], "diskGroup": [ { "diskGroupName": "DATA", "diskPercentage": 80, "redundancy": "FLEX" }, { "diskGroupName": "RECO", "diskPercentage": 20, "redundancy": "FLEX" }, { "diskGroupName": "FLASH", "diskPercentage": 100, "redundancy": "FLEX" } ], "language": "en", "enableAFD": "TRUE", "scan": { "scanName": "oda-scan", "ipAddresses": [ "", "" ] } }, "database": { "dbName": "DB1", "dbCharacterSet": { "characterSet": "AL32UTF8", "nlsCharacterset": "AL16UTF16", "dbTerritory": "SWITZERLAND", "dbLanguage": "FRENCH" }, "dbRedundancy": "MIRROR", "adminPassword": null, "dbEdition": "EE", "databaseUniqueName": "DB1_GENEVA", "dbClass": "OLTP", "dbVersion": "", "dbHomeId": null, "instanceOnly": false, "isCdb": true, "pdBName": "PDB1", "dbShape": "odb1", "pdbAdminuserName": "pdbadmin", "enableTDE": false, "dbType": "RAC", "dbTargetNodeNumber": null, "dbStorage": "ASM", "dbConsoleEnable": false, "dbOnFlashStorage": false, "backupConfigId": null, "rmanBkupPassword": null } }

Of course the same can be done from command line. Here are my database created in this simulation:

[[email protected] /]# odacli list-databases

ID                                       DB Name    DB Type  DB Version           CDB        Class    Shape    Storage    Status        DbHomeID
---------------------------------------- ---------- -------- -------------------- ---------- -------- -------- ---------- ------------ ----------------------------------------
cc08cd94-0e95-4521-97c8-025dd03a5554     DB1        Rac      true       Oltp     Odb1     Asm        Configured   782c749c-ff0e-4665-bb2a-d75e2caa5568

This is the database created by this simulated deployment.

This is really nice to learn or check something without accessing a real ODA. There’s more in a video from Sam K Tan, Business Development Director at Oracle: and the hands-on-lab handbook to know more. And about real-live ODA problems and solutions, I have awesome colleagues sharing on our blog: and they give the following trining: in French, German, English, in site or remote.
