Oracle Cloud Infrastructure – A short Blog Post about a secure and small Development Setup

Author: Martin Berger 14. January 2021

For an internal project I had the pleasure to setup a new Oracle Cloud Infrastructure environment for an APEX development team. Here is a short overview about the setup.

Requirements

VPN Access from everywhere – 2 people are working maximal at same time on the environment
Oracle Standard Edition 2 – no license available in project
Small monitoring to verify server stats
Instances can be started and stopped from the developers to save costs for example over night, weekend, holiday etc.

Architecture Diagram

Resource	Network	Usage	Remarks
Open VPN Access Server	Public Subnet	VPN client access and traffic routing	OCI Cloud Marketplace Image – OpenVPN Access Server (2 FREE VPN Connections) – OpenVPN Inc. – Oracle Cloud Marketplace
Management Server	Private Subnet	OCI-CLI, Monitoring	Application server and database node start/stop with OCI-CLI, Grafana and Prometheus for monitoring
Application Server	Private Subnet	Tomcat ORDS, APEX	–
Database System	Private Subnet	–	OCI Database Standard Edition 2, Backup to Object Store enabled

Network Components

Regional private and public subnet
Security lists and network security groups
Private and public routing table
NAT gateway for regional private subnet

Monitoring

Grafana and Prometheus, running on the management server. The free shape VM.Standard.E2.1.Micro fits perfect for this small setup! The Prometheus node exporter runs on the database and the application server. I used this Grafana dashboard here: Prometheus Node Exporter Full dashboard for Grafana | Grafana Labs

Next Steps

Adding Influx DB for persistence
Adding the Oracle database to Grafana monitoring
Optimizing shape size for the database server according usage

Other Ideas

Create a blueprint for internal developer environments
Automate the setup with Terraform and Ansible

Summary

Setting up this infrastructure in Oracle Cloud Infrastructure was fun. All developer requirements are fulfilled. Started with the Network and OpenVPN configuration – I really like their Marketplace instance – and the moved on to application and database server, step-by-step. There are many other ideas what we can do more based on this setup, the work will not run out. #ilike

Oracle Cloud Infrastructure Data Safe – How to burn down 201.44 Swiss Francs in 30 Seconds…

Author: Martin Berger 11. January 2021

Is Data Safe really for free?

In the last autumn, the new Oracle Cloud Infrastructure feature called Data Safe was released. For sure, new features has to be tested. I have tested the Data Safe feature too and added a cloud database to Data Safe. But in my enthusiasm about this cool feature – or maybe it was just too late in the evening – I did a mistake by adding the database target. Four days later, I recognized that Data Safe is charged in my account. Mmm, but should it not be for free? First reaction: I raised an SR and described the case. The nice guy from My Oracle Support realized the situation quickly:

Dear Mister Berger, you have used the wrong target type when adding the Oracle Cloud Infrastructure database as a new Data Safe target.

From the Service Request:

B91632 – Oracle Cloud Infrastructure – Data Safe for Database Cloud Service – Each (Includes 1 million audit records per target per month) – Free
B91631 – Oracle Cloud Infrastructure – Data Safe for Database Cloud Service – Audit Record Collection Over 1 Million Records (over 1 million audit records per target per month) – 0.0800 / 10,000 Audit Records Per Target Per Month
B92733 – Oracle Cloud Infrastructure – Data Safe for On-Premises Databases – Target Database Per Month – 200.00 Target Database Per Month + Includes 1 million audit records per target per month (pre-requisite under B91632)

Indeed, indeed. According My Oracle Support I have used the wrong target type. Instead Oracle Cloud Database, I used Oracle Database on Compute. And did not realized, the mistake and ignored the text below to the dropdown box. Shame on me 😉 – here is the small, but important difference:

So far so good, the mistake was recognized. I deleted the target and added it from scratch with the correct target type. But this didn’t help, the charging went on.

Oracle Cloud Infrastructure Price List

Adding an other target type than Oracle Cloud Database is charged on monthly fee base as described here: Cloud Price List | Oracle

Cost and Usage Report

In the detailed cost and usage report, the target is marked as deleted (suffix DELETED + deletion date), and charged.

All you can do is getting angry about that mistake and wait. After a month, the money was burned down, and there were no more Oracle Cloud Infrastructure Data Safe costs charged. As you can see, there are 201.44 CHF charged for a month.

I don’t know what Oracle has for a currency converter, but actual 200 USD are less that 180 CHF 😉

Lessons learned

Pity about the beautiful money – and for my next test run: RTFM.

Red Hat Ansible Tower Upgrade from 3.5 to 3.8 – when running setup.sh is not enough – or: I have made fire!

Author: Martin Berger 22. December 2020

I a customer project I had to update an existing Red Hat Ansible Tower setup from version 3.5.1 to the newest available version 3.8. The upgrade scenario as described in 8. Upgrading an Existing Tower Installation — Ansible Tower Installation and Reference Guide v3.8.0 does not work here. For example: the delivered setup.sh is not able to restore data exported from Postgres 9.6 into a new Postgres 10 database. This upgrade scenario as described is a result of a long discussion with Red Hat support (Thanks to Swati – he did a great job!) and an intensive test period on local virtual machines until the live system was in the row.

Remark: The servers in this blog post are listed without domain names to make it easier readable.

The running Ansible Tower Setup

It contains three Red Hat Ansible Tower servers and the repository. All servers can connect among each other. Firewall ports are opened.

Server	Tower Version	Operating System	PostgreSQL Version	Remarks
ansible-tower-01	3.5.1	RHEL 7.8		no Internet access
ansible-tower-02	3.5.1	RHEL 7.8		no Internet access
ansible-tower-03	3.5.1	RHEL 7.8		no Internet access
ansible-db03		RHEL 7.8	9.6	no Internet access, runs on port 5432

Upgrade Path

This documents describes the upgrade path, a release cannot be more than two release numbers behind to upgrade it. In our case, Tower 3.5.1 needs to be updated to 3.7.1 first before 3.8 can be applied. Ansible Tower 3.8 requires Postgres 10.

What are the Recommended Upgrade Paths for Ansible Tower? – Red Hat Customer Portal

Bundles: We use bundles (aka offline installers) for version 3.7.4 and 3.8 – the Ansible Tower servers don’t require internet access to upgrade and install relevant packages. They are included in the bundle. The bundles are accessible by the Ansible Tower server where the setup processes are executed.

Bundle	URL	Note
3.7.4.1	https://releases.ansible.com/ansible-tower/setup-bundle/ansible-tower-setup-bundle-3.7.4-1.tar.gz	free download
3.8	https://access.redhat.com/downloads/content/480/ver=1.2/rhel—7/1.2/x86_64/product-software	requires a Red Hat subscription to download

Prerequisites

The software and the inventory file of the current Ansible Tower installation
Bundle of the future releases are downloaded
Postgres 10 installed on database server
A Red Hat Subscription Manifest File which contains the license information for Tower 3.8 – the Manifest file can only be created in the Red Hat account when a valid subscription is available

Upgrade Overview

Shutdown all involved virtual machines properly, create a snapshot for fallback, restart all involved servers properly
Install Postgres 10 on database server and create a new Postgres 10 database
Manual export/import tower data into the new database with pg_dump/pg_restore
Re-run Ansible Tower 3.5.1 setup against new database
Upgrade to Ansible Tower 3.7.1
Upgrade to Ansible Tower 3.8
Add Red Hat Subscription Manifest
I have made fire!

1. Shutdown Machines and create Snapshot of the Hosts

It is highly recommended to create a backup/snapshot of the existing environment in case of upgrade troubles. In my case, we did VMWare vRealize Automation snaphots first after shutting down tower and database properly.

Tower and Database Shutdown

ansible-tower-01 / ansible-tower-02 / ansible-tower-03: stop the tower service:

# ansible-tower-service stop

1	# ansible-tower-service stop

db03: Stop the database service:

# systemctl stop postgresql-9.6.service

1	# systemctl stop postgresql-9.6.service

Create a backup or snapshot

In my case, we did VMWare vRealize Automation snaphots first after shutting down tower and database properly.

Restart machines

Restart all involved servers and verify in the Tower UI that everything works properly. Tower and database are configured as OS service, they are started automatically after server power on.

2. Install Postgres 10 on database server and create a new Postgres 10 database

Install Postgres 10

Connection details of the new repository database:

Host: ansible-db03
Port: 5433 (old Tower repository was 5432)

There is no internet access to the official PostgreSQL yum repository. Therefore, download the following files from https://download.postgresql.org/pub/repos/yum/10/redhat/rhel-7.8-x86_64/ and copy them to /tmp to the databse server. Ansible Tower 3.7.x requires PostgreSQL 10. It does not work with a newer version! See here: https://docs.ansible.com/ansible-tower/latest/html/installandreference/requirements_refguide.html.

$ sudo su -
# yum localinstall ./postgresql10-server-10.14-1PGDG.rhel7.x86_64.rpm \
postgresql10-libs-10.14-1PGDG.rhel7.x86_64.rpm \

$ sudo su -

# yum localinstall ./postgresql10-server-10.14-1PGDG.rhel7.x86_64.rpm \

Create a new PostgreSQL Cluster with Trivadis pgOperate

On the database server ansible-db03, a new cluster database is required with PostgreSQL version 10. Therefore I used pgOperate. pgOperate is part of the Open Source tool pgBasEnv. My Trivadis colleagues have developed a really cool framework to manage PostgreSQL clusters. Both tools with the manuals and examples are available on GitHub:

GitHub – Trivadis/pgbasenv: pgBasEnv – PostgreSQL Base Environment Tool

GitHub – Trivadis/pgoperate: pgOperate – PostgreSQL Operation Tool

Example to create a new cluster when the tools are installed in base directory /var/lib/pgsql/tvdtoolbox. You will find more information how to configure and how to use the tool on the GitHub pages.

$ cd /var/lib/pgsql/tvdtoolbox/pgoperate/etc
$ cp parameters_mycls.conf.tpl parameters_tower01.conf
$ vi parameters_tower01.conf

$ cd /var/lib/pgsql/tvdtoolbox/pgoperate/etc

$ cp parameters_mycls.conf.tpl parameters_tower01.conf

$ vi parameters_tower01.conf

Set the cluster parameters to create a new cluster which is running on port 5433:

TVD_PGHOME_ALIAS=pgh1014
PGSQL_BASE=/u01/app/postgres/tower01
PG_PORT=5433
PG_SUPERUSER_PWD=<see keepass>

TVD_PGHOME_ALIAS=pgh1014

PGSQL_BASE=/u01/app/postgres/tower01

PG_PORT=5433

PG_SUPERUSER_PWD=<see keepass>

Set the alias and execute cluster creation script.

$ pgh1014
$ pgoperate --create-cluster -a tower01

1 2	$ pgh1014 $ pgoperate --create-cluster -a tower01

Run root.sh to enable automated startup and allow user postgres to start/stop the service.

$ sudo su -
# /u01/app/postgres/tower01/scripts/root.sh

1 2	$ sudo su - # /u01/app/postgres/tower01/scripts/root.sh

Login as user postgres and verify the new created cluster which is started automatically. Here you can see the old PostgreSQL database version 9.6 running together with version 10 as output from the status screen after login.

$ sudo su - postgres

Verify that the file pg_hba.conf allows traffic to the database, for example allow database connects from each server:

$ vi /u01/app/postgres/tower01/etc/pg_hba.conf

# Database administrative login by UNIX sockets
# note: you may wish to restrict this further later
local all postgres peer

# TYPE DATABASE USER CIDR-ADDRESS METHOD
local replication all trust
local all all md5
host all all 0.0.0.0/0 md5
host all all ::/0 md5

$ vi /u01/app/postgres/tower01/etc/pg_hba.conf

# Database administrative login by UNIX sockets

# note: you may wish to restrict this further later

local all postgres peer

# TYPE DATABASE USER CIDR-ADDRESS METHOD

local replication all trust

local all all md5

host all all 0.0.0.0/0 md5

host all all ::/0 md5

0.0.0.0/0 ensures, that all Ansible Tower servers can connect to the new database. This does not implicit allow everybody to connect. For example you can control the access on OS firewall level.

Create a new Database for Tower Repository

Login as user postgres and start psql against the new cluster. In this case, we create a new database called tower10 with same username and password as the existing database.

$ psql -p 5433
postgres=# CREATE USER tower WITH ENCRYPTED PASSWORD 'thisismypassword';
postgres=# CREATE DATABASE tower10 OWNER tower;

$ psql -p 5433

postgres=# CREATE USER tower WITH ENCRYPTED PASSWORD 'thisismypassword';

postgres=# CREATE DATABASE tower10 OWNER tower;

Verification

Test the database connection from all Tower servers to avoid firewall or configuration issues and verify if the new created database tower10 is listed.

$ psql -U tower -p 5433 -h ansible-db03 -d tower10

psql (10.14)
Type "help" for help.

3. Manual Export / Import of Ansible Tower Repository Data

In this step we migrate the tower database to the new PostgreSQL 10 database. It’s recommended to stop the Ansible Tower before starting the export.

ansible-tower-01 / ansible-tower-02 / ansible-tower-03: stop the tower service:

# ansible-tower-service stop

1	# ansible-tower-service stop

Export Data

# Backup
pg_dump -h ansible-db03 -p 5432 -U tower -F c -b -v -f "/var/lib/pgsql/dbexport_tower_3.5.1.backup" tower

1 2	# Backup pg_dump -h ansible-db03 -p 5432 -U tower -F c -b -v -f "/var/lib/pgsql/dbexport_tower_3.5.1.backup" tower

Import Data

# Restore
pg_restore -h ansible-db03 -p 5433 -U tower -d tower10 -v "/var/lib/pgsql/dbexport_tower_3.5.1.backup"

1 2	# Restore pg_restore -h ansible-db03 -p 5433 -U tower -d tower10 -v "/var/lib/pgsql/dbexport_tower_3.5.1.backup"

Stop and disable existing Postgres 9.6 Database

# systemctl stop postgresql-9.6.service

1	# systemctl stop postgresql-9.6.service

4. Re-run Ansible Tower 3.5.1 setup against new database

Adapt Inventory

In this step, the existing Tower setup is registered again against the new database. We have to change the inventory file of the existing 3.5.1 installation.

# vi /root/install/ansible-tower-setup-3.5.3-1/inventory

-- old:
pg_port='5432'
pg_database='tower'

-- new: 
pg_port='5433'
pg_database='tower10'

# vi /root/install/ansible-tower-setup-3.5.3-1/inventory

-- old:

pg_port='5432'

pg_database='tower'

-- new:

pg_port='5433'

pg_database='tower10'

Example inventory file of the existing 3.5.1 installation with three Ansible Tower servers. Note: the [database] section is empty, so the setup procedure will not try to install a new database and uses the new one what we have created above.

[tower]
ansible-towert01
ansible-towert02
ansible-towert03

[database]

[all:vars]
admin_password='thisismypassword'

pg_host='ansible-db03'
pg_port='5433'
pg_database='tower10'
pg_username='tower'
pg_password='thisismypassword'

rabbitmq_username=tower
rabbitmq_port=5672
rabbitmq_vhost=tower
rabbitmq_use_long_name=true
rabbitmq_password='thisismypassword'
rabbitmq_cookie=cookiemonster

[tower]

ansible-towert01

ansible-towert02

ansible-towert03

[database]

[all:vars]

admin_password='thisismypassword'

pg_host='ansible-db03'

pg_port='5433'

pg_password='thisismypassword'

rabbitmq_username=tower

rabbitmq_port=5672

rabbitmq_vhost=tower

rabbitmq_use_long_name=true

rabbitmq_password='thisismypassword'

rabbitmq_cookie=cookiemonster

Re-run setup.sh

As user root, execute the setup.sh script on ansible-towert01.

# /root/install/ansible-tower-setup-3.5.3-1/setup.sh

1	# /root/install/ansible-tower-setup-3.5.3-1/setup.sh

Verify the setup playbook result – no failed tasks should occur. The Ansible Tower 3.5.1 runs now with the PostgreSQL database version 10 and is ready to upgrade. Verify if all Tower are running properly and log in in the user interface.

5. Upgrade to Ansible Tower 3.7.1

The software bundle is transferred to the target server. As I don’t have much free space, I moved the bundle on a NFS which is attached on all Ansible Tower servers. It’s recommended to stop the Ansible Tower before starting the upgrade process.

ansible-tower-01 / ansible-tower-02 / ansible-tower-03: stop the tower service:

# ansible-tower-service stop

1	# ansible-tower-service stop

As user root, go to the install directory and extract the bundle.

# cd /nfs/ansible/tower/install
# tar xvfz ansible-tower-setup-bundle-3.7.4-1.tar.gz

1 2	# cd /nfs/ansible/tower/install # tar xvfz ansible-tower-setup-bundle-3.7.4-1.tar.gz

For the inventory file, the same settings as used in 3.5.1 can be used. The RabbitMQ settings are not required anymore and can be removed. This component is removed from Ansible Tower during the upgrade process. Example inventory file:

# vi /nfs/ansible/tower/install/ansible-tower-setup-bundle-3.7.4-1/inventory

Note: Ansible verifies if the ansible RPM version is 2.4 or higher. Only on the node where the installer runs, the ansible package is updated. If you want to upadte the package on the oder Tower servers too, you can force the update of the package to 2.9.15 with the parameter upgrade_ansible_with_tower=1. A manual upgrade on by rpm -Uhv is possible too, the ansible package is available in the bundle.

# /nfs/ansible/tower/install/ansible-automation-platform-setup-bundle-1.2.0-1/setup.sh -e upgrade_ansible_with_tower=1

7. Add Red Hat Subscription Manifest

In former versions, a license file was required. Now it has changed to a subscription manifest. This file was generated in the Red Hat customer portal. After the first login into the 3.8 servers, you have to add the manifest. That’s all folks.

8. I have made fire!

After spending a lot of time to figure out the correct way how to upgrade, doing a lot of tests and finally the implementation on the live system, I did it. After version 3.8 was showing up, I felt like Tom Hanks in the movie Cast Away – I have made fire!

Summary

Upgrading the Ansible Tower with the existing online documentation? No chance! I have opened a support case at Red Had to clarify a lot of this like changing the repository database, updating the ansible packages etc. The procedure with setup.sh -b / setup.sh -r as described in the upgrade documentation did not work. It needs a manual data transfer. I really like the method to install the new Ansible Tower versions with a bundle, so no internet connection is required to keep the environment up to date. Hopefully Red Hat will update the documentation in the near future, for example with an upgrade cookbook section or however they want to call it.

Oracle OCI Data Transfer Service – A journey from Kestenholz/Jurasüdfuss/Switzerland to Frankfurt and back

Author: Martin Berger 24. November 2020

The Oracle Data Transfer service is a offline data transfer method to migrate data to the Oracle Cloud Infrastructure. A transfer service is useful, when your network bandwidth and connection is not sufficient to upload your migration data in a meaningful time. Oracle offers two methods: The disk-based data transfer and the appliance-based data transfer. The service is no only one-way, data can also be exported in an Oracle Cloud Infrastructure data center and shipped to your data center.

According one of my Company Trivadis’ cultural value called curiosity, I was wondering how this service works. This is the story of a tiny USB Hard Disk Drive full of data, which was going on a long journey from Kestenholz / Jurasüdfuss / Solothurn / Switzerland to the Oracle Infrastructure data center in Frankfurt and back.

Setup

The OCI Data Transfer utility is Linux based, the USB 3.0 HDD is attached to a VMware Virtual machine where Oracle Linux is running
The virtual machine has access to the Internet
Data is available – for this example I used some open data from Swiss government (opendata.swiss)

Data Transfer Service Regions

Actually data transfer is available in Frankfurt, Ashburn, Phoenix, London and Osaka. From Switzerland, Frankfurt is the nearest location.

How is your data coming into the Oracle Cloud

Enable Data Transfer Service – Data Transfer
Prepare an Object Storage bucket
Create a Transfer Job
Attach a HDD to a Linux based host, use the Data Transfer Utility to create and encrypt the device
Copy data to the HDD
Create and upload the disk manifest
Lock the disk
Attach the Disk to the transfer label and create the package
Create a transfer package
Shipping and update shipping information
Tracking
Data Verification
Object Storage Replication Policy (optional)
Finally…

Note: Most of the jobs above can be done by the OCI CLI on command line and are very well described in the Oracle doumentation.

1. Enable Data Transfer Service – Entitlement

Before you can use this service, the Data Transfer service has to be enabled in general. Therefore you have to request it. The OCI tenant administrator gets a document, what he has to sign in a digital way. It contains for example a description how to bring data to OCI, and if you order an appliance that there will be a 45day maximum limit where the appliance has to be returned to Oracle. And a few days later, the service is ready to use. Basically now you have the permissions, to order a Data Transfer Appliance, but in this test I used the Disk Service.

2. Prepare an Object Storage Bucket

In the Frankfurt region, I created a new Object Storage bucket called data_transfer_usb. This is the bucket where the shipped data will be transferred in.

3. Create a Transfer Job

In Object Storage – Data Transfer Import, we create a new transfer job. It contains the upload bucket from above and as method the transfer device type is disk. For furtehr processing, we need the OCID of the job. As you can see, actually there is no transfer disk attached.

4. Attach a HDD to a Linux based host, use the Data Transfer Utility to create and encrypt the Device

Prerequisites for the Data Transfer Utility according the documentation:

An OCI Account which have the IAM permissions for Data Transfer
A Linux machine with Oracle Linux 6 or greater, Ubuntu 14.04 or greater, SUSE 11 or greater
Java 1.8 or 1.11
hdparm 9.0 or later
Cryptsetup 1.2.0 or later

Package Installation for my Oracle Linux 7 Machine

# yum install java-1.8.0-openjdk-devel
# yum install hdparm
# yum install cryptsetup

# yum install java-1.8.0-openjdk-devel

# yum install hdparm

# yum install cryptsetup

Download and Installation of the Data Transfer Utility

The actual link to the file is in the online documentation.

# wget https://docs.cloud.oracle.com/tools/dts-rpm/3.0.2461/dts-3.0.2461.x86_64.rpm
# yum localinstall /tmp/dts-3.0.2461.x86_64.rpm

1 2	# wget https://docs.cloud.oracle.com/tools/dts-rpm/3.0.2461/dts-3.0.2461.x86_64.rpm # yum localinstall /tmp/dts-3.0.2461.x86_64.rpm

Test

# dts --version
3.0.2461 ( DEV_NO_HASH )

1 2	# dts --version 3.0.2461 ( DEV_NO_HASH )

Configure IAM Credentials for Data Transfer Actions

The configuration is according configuring the Oracle Cloud Infrastructure CLI with user, fingerprint, key_file, tenancy and region. Example configuration file:

6. Generate Manifest File

It generates a local file which contains a list of the files and her MD5 checksums like an inventory file. Here the disk label is required.

9. Shipping and Shipping Information Update

As shipping company I used DHL Switzerland. They have a pick point near by in Langenthal. At this point, it’s important to organize the return shipping too and put the return shipping label in the box. I didn’t realize it and have forgotten to organize the return shipping. So the disk was stranded in the Frankfurt data center. And then the story began. As a private person, the delivery companies DHL and UPS doesn’t allow private persons to re-import packages from outside Switzerland without a customer number. But, private persons don’t get such a number. Finally with FedEx I was able to organize the return shipping. Thanks to Andrew and Christos from Oracle’s OCI Data Transfer team for their patience!

Note: Companies like DHL have templates to create pro-forma commercial invoices – https://www.dhl.ch/exp-de/express/zollabwicklung/zollpapiere/proforma_rechnung.html#invoice

This disk was sent to the Oracle Cloud Infrastructure data center Frankfurt.

Now the shipping information has to be updated with vendor and the tracking numbers.

# dts package ship --job-id ocid1.datatransferjob.oc1.eu-frankfurt-1.antheljszffzlryauwznondp2zp6rztpbvzyekv12345671234567 --package-label PDQ0QMLNT --package-vendor DHL --tracking-number 5542918614 --return-tracking-number 12345678
Update package: PDQ0QMLNT

10. Tracking

DHL required two days until delivery in Frankfurt. Oracle started one day later with the data import.

11. Data Processing

Then Oracle is uploading the data and the disk is attached, the job transfer status changes to PROCESSING.

# dts package show --job-id ocid1.datatransferjob.oc1.eu-frankfurt-1.antheljszffzlryauwznondp2zp6rztpbvzyekv12345671234567 --package-label PDQ0QMLNT

13. Object Storage Replication Policy (optional)

The files are now in the data center Frankfurt, but I want to have them in the Swiss data center region Zurich. Therefore I set a replication policy on level Object Storage. In Zurich, a new bucket called data_transfer_usb_from_FRA is created. And a few minutes later, the files were available in the Object Storage Zurich. Sure, it depends on the file size 😉

Finally…

Detach the transfer disk so the data center guys can send it back to you.

And after a few days…welcome FedEx in Kestenholz / Jurasüdfuss / Solothurn / Switzerland!

Some words about Shipping and Costs

Shipping costs from DHL and Fedex:

Vendor	From	To	Costs
DHL	Langenthal / Switzerland	Frankfurt	79.50 CHF
FedEx	Frankfurt	Kestenholz	130.45 CHF

Summary

To watch nice marketing slides and documents about cool features is not enough. To find out how it works in the real word, a real is test is required. How to migrate data into a data center of any cloud provider should be basic know-how of each consultant which is working with and on cloud themes. Moving data by a disk ro an appliance opens a lot of possibilities for data migrations into the cloud. For example a huge DWH: Transfer the RMAN backup into the cloud, restore it, close the GAP by an incremental backup and synchronize it with Oracle Golden Gate. #ilike

Oracle Cloud Infrastructure Classic Object Storage – Cleanup Day with FTM CLI

Author: Martin Berger 19. November 2020

Yesterday I decided to cleanup old Oracle Cloud Infrastructure Classic objects. There were a lot of files lying around in the Object Storage of a project from 2018. Cleaning up these files in the OCI console was no option, they can only be deleted one by one. And with over 1500 files, a bad idea. During the search for an option for Object Storage mass deletion, I found this tool: ftmcli – Object Storage Classic File Transfer Manager. The MOS note contains the script and a short manual how to use. It’s a Java based script, a perfect match for my Windows Subsytem for Linux (Ubuntu), which I often use for OCI actions.

OAC-Classic : How To Delete A Storage Container That has Multiple Objects. (Doc ID 2634021.1)

Link to the User Guide: https://docs.oracle.com/en/cloud/iaas-classic/storage-cloud/csclr/preparing-use-ftm-cli.html#GUID-5BB8647F-DDAD-4371-A519-1116402245FB

The Container List

Here is the content of my Object Storage Classic what I have to clean up – it contains five containers.

ftmcli – Installation

Over the WSL mountpoint in /mnt where you have access to your local Windows disk drives, transfer the package to the home directory and extract it.

mbg@DESKTOP-ID2UR6L:~$ unzip ftmcli-v2.4.3.zip
Archive:  ftmcli-v2.4.3.zip
   creating: ftmcli-v2.4.3/
  inflating: ftmcli-v2.4.3/README.txt
  inflating: ftmcli-v2.4.3/ftmcli.properties
  inflating: ftmcli-v2.4.3/ftmcli.jar

mbg@DESKTOP-ID2UR6L:~$ unzip ftmcli-v2.4.3.zip

Archive: ftmcli-v2.4.3.zip

creating: ftmcli-v2.4.3/

inflating: ftmcli-v2.4.3/README.txt

inflating: ftmcli-v2.4.3/ftmcli.properties

inflating: ftmcli-v2.4.3/ftmcli.jar

In the extracted subdirectory is a file called ftmcli.properties – there you have to set your OCI Object Storage information. Two parameters are used:

user=<OCI login>
rest-endpoint=<your Storage Classic Endpoint>

The Storage Classic Endpoint is visible in the Storage Classic Account tab. There is no need to set the password in the properties file. You are prompted for it when ftmcli is executed.

ftmcli – Commands

Available commands – output from ftmcli:

upload	Upload a file or a directory to a container.
download	Download an object or a virtual directory from a container.
create-container	Create a container.
restore	Restore an object from an Archive container.
list	List containers in the account or objects in a container.
delete	Delete a container in the account or an object in a container.
describe	Describes the attributes of a container in the account or an object in a container.
set	Set the metadata attribute(s) of a container in the account or an object in a container.
set-crp	Set a replication policy for a container.
copy	Copy an object to a destination container.

ftmcli – List Object Storage Containers

Here you will be prompted for your OCI password. Curious thing: My existing OCI password what I have used for months contained a lot of special characters( ,LCaOQ3|~[PT”+x), and there were not accepted.

mbg@DESKTOP-ID2UR6L:~/ftmcli-v2.4.3$ java -jar ftmcli.jar list
Enter your password:
ERROR:Authentication failed. Authentication failure

mbg@DESKTOP-ID2UR6L:~/ftmcli-v2.4.3$ java -jar ftmcli.jar list

Enter your password:

ERROR:Authentication failed. Authentication failure

I had to set a new OCI account password with less complexity and special characters and then it worked.

mbg@DESKTOP-ID2UR6L:~/ftmcli-v2.4.3$ java -jar ftmcli.jar list
Enter your password:
_apaas
bdcvision
dbcs-vision
oac-vision
oracle-data-storagec-1

mbg@DESKTOP-ID2UR6L:~/ftmcli-v2.4.3$ java -jar ftmcli.jar list

Enter your password:

_apaas

bdcvision

dbcs-vision

oac-vision

oracle-data-storagec-1

ftmcli – Delete Object Storage Containers

With the -f flag, the deletion of a container which contains objects can be forced. I did it for all my containers.

mbg@DESKTOP-ID2UR6L:~/ftmcli-v2.4.3$ java -jar ftmcli.jar delete -f oracle-data-storagec-1
Enter your password:
Container successfully deleted: oracle-data-storagec-1

mbg@DESKTOP-ID2UR6L:~/ftmcli-v2.4.3$ java -jar ftmcli.jar delete -f oracle-data-storagec-1

Enter your password:

Container successfully deleted: oracle-data-storagec-1

And finally all containers are removed. Job successfully done!

Summary

This is what I like in Oracle Cloud Infrastructure, for a lot of problems and technical questions are a lot of scripts and tools available like this one: ftmcli. But sometimes it’s not so easy to find them.
