Course Guide Week 1 – Basics

Hi everyone,

the first week of the openSAP course Introduction to SAP HANA Cloud Platform (repeat) will provide you with some basics around the platform.

We’ll look into cloud services in general and into SAP HANA Cloud Platform specifically including the development environment and its’ setup.

At the end of this week you’ll have your first application deployed in the cloud and on your local environment.

This document is a detailed blog post around all the units of week 1. The parent document of this blog post provides you with an overview about all blog posts I’ll write throughout the weeks of the course.

Unit 1 – Basics

Definition of Cloud Services

You can find more detailed explanations around the definition of Cloud Services on various places.

The one I really like is on Wikipedia, that you can find under http://en.wikipedia.org/wiki/Cloud_services#Services

The SAP Data Center

You can get detailed information about the SAP Data Center on the SAP Data Center home page.

Integration With Other Systems

SuccessFactors Integration

Be informed that we are planning to hold a complete new course around extensions on the SAP HANA Cloud Platform.

Stay tuned for more information, we’ll share it soon.

Unit 2 – Your Account

The Most Important Links

Getting An Account

Find a more detailed explanation on the official documentation.

Pricing For Various Packages

Get a detailed drill-down of the prices and the various resources you can purchase for the SAP HANA Cloud Platform here.

Different Design on Account Cockpit

You’ll find a difference in the look-and-feel of your account cockpit compared to the one you see in the videos.

This is due to a change in the colors of the user interface. There are also additional tabs due to an update of the platform with additional functionality.

In the new design the “Applications” have been renamed to “Java Applications“.

You also have a new tab called “HANA Packages” for the HANA XS applications that you can also deploy on SAP HANA Cloud Platform.

For the oAuth support there is also an additional tab called “oAuth“.

Former design:

New design:

Unit 3 – Setting Up The IDE

System Requirements

Read the list of product restrictions to get to know how you can use the SAP HANA Cloud Platform.

Setting up JAVA

You need Java 6 or Java 7 installed on your machine. You need also to make sure that the java path is set in the “PATH” environment variable and also as “JAVA_HOME” – Get more details.

Open a command window in the <HCP_SDK_PATH>\tools folder. Execute “java -version” to check what is the version of your java and verify that it is the one you expect. <HCP_SDK_PATH> is the path in the file system where you unzipped the HANA Cloud Platform SDK.

You can check if the JAVA_HOME is correctly set by executing the “set” or “env” command – both commands are listing all the environment variables you have.

Java 1.8 is not supported.

SAP HANA Tools: For Eclipse Kepler only

In case you are running Eclipse Juno you are not able to select the SAP HANA Tools. The SAP HANA Tools are available only for Eclipse Kepler.

So in case you want to install them you need to use Eclipse Kepler.

Issues with installing Eclipse

In case you have issues with installing Eclipse, please check-out this thread first to find out if you can fix it with the hints provided there.

Port Number Of Local SAP HANA Cloud Platform Server

When adding a server of type “SAP HANA Cloud local runtime” it can happen that you’ll be assigned another port than 8080 to that server. This is the case whenever that port is already used by an application running on your machine.

For the course this is no issue at all. Simply use that port instead of the standard port 8080. If you forgot the port number of your local SAP HANA Cloud Platform runtime just double-click on the server entry in Eclipse and you’ll see the port inside the newly opened window in Eclipse (see screenshot below):

On Windows you can find out which applications are running on which ports with the following commands in your command line:

netstat -a -b -p TCP

There should be a line like

TCP 0.0.0.0:8080

TCP 127.0.0.1:8080

In the next line the file name of the program is given.

Using other JRE than JRE 6

Nearly all of the sample projects use JRE 6. In case you have another JRE installed on your machine you can either install JRE 6 on your machine and point Eclipse to that installation (Eclipse Preferences>Java>JRE).

Alternatively you change the project properties of each sample project by right-clicking the project and clicking on Properties > Java Build Path > Libraries. After that double click the JRE System Library entry and select the other (Alternate) JRE you are using:

Using the SAP JVM

For those of you installing the sap jvm don’t forget to add this setting to the eclipse.ini after the -vmargs option:

-XX:MaxPermSize=256m

Without this you will experience weird things with eclipse hanging all the time.

Introduction to Eclipse (and Java)

In case you have no experience at all with Eclipse I can recommend the free video course Eclipse and Java for Total Beginners. The course assumes you have no experience with Eclipse or Java and brings you up-to-speed in 16 lessons.

Unit 5 – Deploying The First Application

Common Issues

When deploying your first application to the cloud you might run into some issues listed below with some measures to fix the issues.

Using Wrong Connection Details / Authentication Issues

The most prominent one is the usage of wrong connection details.

Ensure you are using the correct host for your trial account. This is hanatrial.ondemand.com and NOT hana.ondemand.com

Also be sure to use the correct account name and user.

The account name is something like Pxxxxxxxxxxtrial and the user name is Pxxxxxxxxxx.

You can get your account name at your account cockpit. It’s at the top left corner under the text “Account”.

In such cases you should follow the following steps:

connect to your HANA Cloud account cockpit (https://account.hanatrial.ondemand.com/cockpit) with your credentials
Can you connect to that? If yes, move on with step 3. If no, please check your credentials again and go to step 1
Check the account name that is displayed on the top left under “Focus Object”, “Account”. This should be something like xxxxxxxtrial where xxxxxxx is your username
Now switch to Eclipse and follow the instructions from 05:42min to 07:04min. Check your proxy settings in case you are working behind a proxy! Ensure you are using the account name and the user you saw on your cockpit. Don’t forget that the host is hanatrial.ondemand.com and NOT hana.ondemand.com
Add the application to your server as shown from 08:18min to 08:37min.

If you follow those steps you should be able to deploy the app.

Forgotten Password /Authentication Issues

Sometimes users forget their password for their account or don’t know it (e.g. if they are SAP employees that get to the account cockpit with SSO).

In such cases you can follow these steps:

Go to https://account.hanatrial.ondemand.com/
If you don’t see the Register button please log off by clicking on the corresponding icon on the top right
Click on the Register button (yes, please click on Register although you are already registered 🙂
Now don’t fill out any fields besides the field for your email address
Once you’ve typed-in your email-address switch to another field in the form
You’ll get a little pop-up window next to your email-address where you need to click on the link “Forgot Password”
Once you’ve clicked on “Forgot Password” you’ll receive an email with an activation link
Copy-and-paste that link (and don’t click on it) into your browser
You’ll now be able to provide a new password. That’s the password you’ll need to deploy applications to your SAP HANA Cloud Platform account

Please be aware that you can change your password only once within every 24 hours.

Could not reserve enough space for object heap

If you get this message in the Console view of your Eclipse when deploying an application to your local machine you can try the following possibilities:

Possibility 1: You’ve installed a 32bit Eclipse on a 64bit computer. Try using the 64bit Eclipse on your 64bit computer and check if that helps.
Possibility 2: You might be able to fix it by increasing the Timeout setting of the local server runtime. This issue can happen if you have a very slow computer.
To do that you double-click on the local server in the Servers view in Eclipse. A new window for the server’s properties opens up and you select “Timeouts” and set “Start” to 120 seconds.
Thanks to Stuart Pratt for this hint that he added as a comment to this blog post.
Possibility 3: Following the same steps as above until you see the window in your Eclipse for the “SAP HANA Cloud local runtime”. Click on “Open launch configuration”, switch to the tab “Arguments” and under “VM Arguments” search for the text -Xmx1024m and substitute it with -Xmx512m. Save your changes (click on Apply and OK) and try again.

Less Common Issues

Error message: ‘Server SAP HANA Cloud local runtime failed to start”

‘findstr” is not recognized as an internal or external command

When switching to the Console view you see an error message telling you that ‘findstr” is not recognized.

The problem is most probably related to your system PATH variable. This means that C:\Windows\System32 is not inside you PATH. Just add it and restart Eclipse and this should work. Find some detailed descriptions how to add something to your PATH in these instructions:

Hey Rui,

The issue with Windows 8 has been fixed in the beginning of the year – you can safely remove the reference to the workaround.

Cheers,

Hello Rui,

i’m watching your Course today and i’m at Unit 5 deploying the first application. But the trying to deploying the application to the cloud constantly my SAP HANA cloud platform local runtime does not start. It keeps telling me the same error as you mentioned in the Comon Issues on this page

Error message: ‘Server SAP HANA Cloud local runtime failed to start”

i have checked my server settings and account settings.

However in my loacl workspace under //Users/d002688/SAP HANA Cloud Platform local runtime-config the file “sap hana cloud platform local runtime-config_daemon.log” contains an error saying that my local host name is unknown.

“

Fehler: Ausnahme von Agent ausgel?st : java.net.MalformedURLException: Local host name unknown: java.net.UnknownHostException: WDFM00356478A: WDFM00356478A: nodename nor servname provided, or not known”

Im working over VPN. But i got lost and i dont know what to do.

Best Regards

Juergen

  Hi Juergen, thanks for the note.
  
  I see you’re an SAP colleague. Ideally just send me an email with some screenshots of the popup window where you select the server, and you provide your credentials.
  
  Once I identified the issue I’ll post the solution into my blog post above.
  
  Best,
  
  Rui
  
  PS: It’s better if you post your questions into the forum of the course. Many of my colleagues are watching those forums and can help much faster than I can do.

  Hi Rahman, seems like there is a problem with your secure storage. Simply try to provide your credentials without putting the tick on the “Save password (could trigger secure storage login)”.
  
  If that doesn’t work you might have to delete the secure store. To do that go to the Eclipse preferences and do “Preferences”, “General”, “Security”, “Secure Storage”, “Contents” and after that click on “Delete” and restart Eclipse. Should work.
  
  Best,

Hi Rui,

I have followed all the steps as in the first 4 units, I am trying to start the SAP HANA Cloud Platform local runtime server and I am getting “Server SAP HANA Cloud Platform local runtime failed to start.” . The port I am using is 8080 and it is not used by any program in my laptop. My laptop is a Linux Open Client for Linux RHEL 6.5 Editio.

Java 1.7 and Eclipse Java EE IDE for Web Developers. Version: Kepler Service Release 2 Build id: 20140224-0627.

I can’t see that I have generated any loggs to check the errors. At this point I am not sure what to look into to resolve my problem.

Any idea what should I be looking for?

Thanks,

Raji

  Hi,
  
  Can you try to do the same by installing Java 1.6 and removing Java 1.7.
  
  I am facing a different error, NullpointerException while importing hello-world project. Also I find no ‘src’ folder in eclipse –> project explorer. since I have both Java 1.6 and Java 1.8 installed, I am uninstalling 1.8, to check if it works. Will keep posted.
  
  Thanks.

    a) changing the workspace
    
    b) update to eclipse tools
    
    c) clean start of eclipse IDE.

However after adding SAP Server, I see a message in Error Log tab as follows. I am not sure if I added SAP Server successfully.

  Hi Anup, in the error message I see that you defined your landscape host as hanatrail.ondemand.com. But it should be hanatrial.ondemand.com.
  
  Try that out and it should work, if your proxy settings are correct it should work.

    Haven’t pasted complete error trace.
    
    Any suggestion on fixing this error?
    
    Also, when I try giving ‘localhost:8080/hello-world/’ in the IE browser, it doesn’t recognise.
    
    Cheers,

    Hi Rui,
    
    I am unable to proceed due to this error. I tried deleting the local runtime server and created it again but error persist.
    
    Am I missing any settings? Any suggestion?

      Hi Anup,
      
      you can proceed with the excercises and ignore this message, since we will not use JCo scenarios in this course. The error stack trace states this explicitly:
      
      …
      
      If you don’t develop a JCo scenario for HANA Cloud, you can ignore this issue.
      
      …
      
      However, if you really want to avoid this error, you must first download the SAP JCO from
      
      http://service.sap.com/support -> Software Downloads -> Support Packages and Patches -> Browse our Download Catalog -> SAP Connectors -> SAP JCO -> SAP JCO 3
      
      Choose your system and download corresponding ZIP archive. Inside of the archive check the readme file for installation instructions. After installation restart Eclipse and start the local runtime. The error shouldn’t be there anymore
      
      Best regards,
      
      Artem

        Hi Artem
        
        Thanks for your suggestion. I’ll proceed with other exercise ahead.
        
        I’ll install SAP JCO as mentioned in your reply and try it out this as well.
        
        Thanks once again. Appreciate your help.

        Hi Anup,
        
        if you say “with other excercises”, does it mean that you can’t proceed with one of the excercises? If so, then I think there is another problem since the issue with JCo shouldn’t have influence on the work. Until yesterday I had the same log message and could make all of excercises
        
        Best regards,
        
        Artem

        Hi Artem,
        
        Thanks for your reply.
        
        As mentioned earlier, I managed to publish Hello World app successfully in cloud but not able to do it on local-runtime due to this error. I haven’t tried any week 2 exercises yet which I’ll be trying out in next 2 days time. Hopefully I don’t need to worry about this error with any other exercises required further in this course.
        
        I haven’t managed to download JCo as per your suggestion from support site as I am facing some issues with my support id (S*) log-in.
        
        Cheers,

Hi Rui,

Great course!

I have one question. I can’t get rid of one error as per the screenshot.

The local server starts and synchronizes but the error is still there.

I was able to sucessfully run Hello-world application locally and do the same on cloud but for some reason it doesn’t work on local anymore – I tried restarting the server, different browsers but I only get a blank page or webpage not found.

I’m not sure if the Java error is related to the Helo-world not showing up anymore as it worked before but your help on both would be much appreciated.

Thanks in advance,

Maciej

  Hi Maciej, not sure what might have happened. The easiest way is to delete the server again from your servers view and add a new on again.
  
  Best,

    Hi Rui,
    
    Thanks, I deleted the server, added it again and it worked.
    
    I think the problem is in the debug mode. When I start the local server in the debug mode (Debugging) I can’t access the application through browser (blank page or error404). After that when I stop the server and start it again in the normal mode (Started, Synchronized) I still get nothing on the browser. I need to delete the server and add it again as you said.
    
    This is strange as it prevents me from using the debug mode entirely. Unless I’m doing something wrong.
    
    Would you have any advice?
    
    Thanks,
    
    Maciej
    
    ps. I have other question but I will post it on the forum as advised.

      I am also getting same error. Even after deleting the server and adding it again, error still persist. Do you know the solution for this? Due to this I am unable to get Hello World application working in my local runtime.
      
      Any suggestion?

  Hi Joanna, are you sure you’ve provided the right proxy settings as I’ve described in my blog above? This is of course only relevant, IF you are working behind a proxy.

Hi there,

I’m having issues running the Console client. I keep getting an error when trying to open the program then it very quickly shuts the program down. I’ve installed the SDK twice no and it still does this. Any suggestions?

also the Runtime logs are not available.

Thank you for your help

  Hi Sean, to open the console client you need to open a terminal on windows (command + R) and change to the directory where the neo.bat file is.
  
  After that you can call the console client with the corresponding commands.
  
  Best,

  Hi Indre,
  
  please change the default JRE to java 1.6 or java 1.7 (Window -> Preferences -> Java -> Installed JREs). After that remove the server and create a new one. This should work.

Hi everybody, sorry, but I will close this blog post for comments. Please use SAP HANA Cloud Platform Developer Center SAP HANA Cloud Platform Developer Center or the corresponding openSAP forum for week 1 of this course to post your questions regarding the openSAP course.

Otherwise we have to look into too many different places to look for questions.
