Oracle Cloud

Created Oracle.com account, Oracle account requires work/ .edu email address only during registration

Used [email protected], account name usscu. Total time spent to configure and host this HelloWorld

Java App is ~5 hours. Details listed below.

I have an option to request multiple free trial accounts using my scu email id, request submitted on 10/7

got provisioned instantly

Recent changes: Front page UI change, i.e how SaaS, PaaS and IaaS services are grouped and displayed

I requested free trial PaaS service this time, last month when I requested I could specify JCS and

Developer cloud service from PaaS portfolio.

Believe this is recent change and a good one; this makes it easy as they combined all the PaaS services

(Oracle Database, Java, Compute, Developer, Database Backup, Storage, Application Container,

SOA Cloud Services) during Free trial. They provision all.

I am yet to see $200 free credit option that is expected to be available. Trial instances are expected to

be kept when transitioned to paid account.





PaaS registration confirmation

Approval/provisioned email rcvd under 10 minutes.



https://www.youtube.com/watch?v=T_DnKeGdXhA Deploying Java Application to JCS

From the JCS and DBaaS Cloud pages, these How to videos are taken.

https://www.youtube.com/embed/J2GNjALHaT4?rel=0&autoplay=1 DBaaS new used it

https://www.youtube.com/embed/b3T_MuB-7WY?rel=0&autoplay=1 from JCS latest

https://www.youtube.com/embed/T_DnKeGdXhA?rel=0&autoplay=1 from JCS latest

Lots of configuration needed: For Java we need, Public Private key pair using Putty, DBaaS, Storage

Container configs(backup), weblogic id and password, assuming we have .WAR file ready to upload

from eclipse.

Multiple passwords I had to create in the process, each password has different rules on what characters

it can contain!, length of 8 worked always

Whats positive in this process is Howto-videos are clear with one exception, where not just me others

also seem to be stuck.

Issue occurs while configuring JCS to talk to DBaaS: https://community.oracle.com/thread/3808527

Too many passwords:

1.Oracle account password

2.Oracle cloud account password during setup.

3.Java Cloud Service requires DBaaS configuration first. Weblogic id and password config

4.DBaaS requires SSH(public private keygen thru Putty) , DB admin password.

I used these videos listed on Free Trial JCS and DBaaS to configure

1. https://www.youtube.com/embed/J2GNjALHaT4?rel=0&autoplay=1 db new used 2. https://www.youtube.com/embed/b3T_MuB-7WY?rel=0&autoplay=1 from JCS latest used 3. https://www.youtube.com/embed/T_DnKeGdXhA?rel=0&autoplay=1 from JCS latest used

You fallow step by step of whats listed in these videos, you can not connect Java to DBaaS, needed

Internet help to figure I needed to use ‘sys’ Vs SYSTEM

After that is resolved, I successfully created DBaaS, JCS and hosted java.war created from eclipse using

weblogic hosting JavaApp using weblogic. That app is running. I was so excited to view result on

browser. My DBaaS and JCS services are stoped since I rantout of allotted quota!

I had to think logically and remove load balancing/clustering options to save OCPU. I did not find easy

option to do this ( explored Scale down of DB option, I could not find way to undo compute space, so

only option I had was to re-install Java Service)

recommended using Load Balancing

I found below note after couple of failed attempts to download toolkit and searching web for answers:

https://azure.microsoft.com/en-us/documentation/articles/azure-toolkit-for-eclipse-installation/

Important:

If you are using the Azure Toolkit for Eclipse on Windows, the toolkit requires installing

the Azure SDK 2.9.1 or later. You have two options for installing the Azure SDK:

You can download and install the Azure SDK by using the Web Platform Installer (WebPI).

If you do not have the Azure SDK installed when you create your first Azure deployment project,

you will be prompted to automatically download install the requisite version of the Azure SDK.

Note that the Azure SDK is only required on Windows.

Above link is not accessible, has been de-activated by Digital Ocean in an hour time , please find above

Note from EMGT SCU team2 answer on why hosted link is not working?

The site http://192.241.228.133:8080/ was working properly earlier.Kindly check the screenshot attached in

the document.

I wonder what had happened and DO people blocked my droplet IP and that's the reason why now we

are not able to connect the site.They have mentioned some outgoing Denial of Service attack issue.

I have no clue,what are these attacks and why they blocked my IP and separated it from the Internet.I am

not able to login into my droplet using root password now and Tomcat service is also stopped which is

the reason of inaccessibility of the site.

I have mailed DO team to check the issue.Hoping to get their reply soon.

Kindly let me know what can we do now.

--

Mail from DO for your reference:

Hi there,

We've detected an outgoing Denial of Service attack (http://do.co/21Y1Gc1) originating from your Droplet. Due

to the traffic’s harmful nature, your Droplet was taken offline; this means it is not connected to the internet and

all hosted sites and services are unreachable. We know that this action is disruptive, but it’s necessary to protect

you, our network, and the target of your Droplet’s attack.

You can access your droplet using this console link: https://cloud.digitalocean. com/droplets/28113740/console

http://192.241.228.133:8080/

http://do.co/21Y1Gc1

https://cloud.digitalocean.com/droplets/28113740/console



Because this means your Droplet has been compromised, you’ll need to back up your data and transfer it to a

new Droplet. We have a recovery tool to assist you, but any databases on your Droplet will need to be backed

up before we boot your Droplet into the recovery tool because you won’t be able to make the backups

afterwards.

Specific backup steps vary depending on the database software in use, which is most commonly MySQL. If

you’re not sure how, http://do.co/1h0uWgm will show you how to back up your databases from MySQL.

Once you have finished backing up your data, the next step is downloading and transferring your data to your

new Droplet. Please update this ticket when you’re ready and we’ll configure this Droplet so you can proceed.

If you’ve enabled our backup service or have a snapshot of the Droplet, you can restore directly from that

image instead of going through the recovery process. Be aware that this will destroy any changes or additions

made to the Droplet since the creation date of the image you use to restore from. If you do this, please update

the ticket as we will need to reconfigure networking to get your Droplet back online.

If you don’t need the data from this Droplet, you can destroy this Droplet at your convenience. If you’d like to

keep the current IP address, you will need to use our rebuild function. This acts like a clean install of your OS

and is currently the only way to ensure you retain your IP. As with restoring from an image, please let us know

once you’ve done this.

If you have any further questions, or if we can further assist, please let us know.

Regards,

Trust & Safety
