HANA multi-tenancy feature

1. May i know if HANA supports multi-tenancy on production system now?
2. Also, we found that 'HANA supports the multi-tenancy that built in the application (e.g. CRM) itself'.
Is it about the SAP HANA cloud applications but not for on premises applications?
Is this statement valid and what are the differences between the 1. and 2.?

Hi Joey
Wikipedia meaning:
Multitenancy refers to a principle in software architecture where a single instance of the software runs on a server, serving multiple client-organizations (tenants). Multitenancy contrasts with multi-instance architectures where separate software instances (or hardware systems) operate on behalf of different client organizations. With a multitenant architecture, a software application is designed to virtually partition its data and configuration, and each client organization works with a customized virtual application.
reference: Multitenancy - Wikipedia, the free encyclopedia
1. May i know if HANA supports multi-tenancy on production system now?
There is a pilot program ongoing for VMWare.
So far, such scenario's are not yet officially supported to my knowledge for productive use.
What I understand under multi-tenancy here is that I could for example serve two customers with one HANA appliance, by running both customers ERP on the same HANA appliance (each with their own DB so two HANA database installations on one HANA appliance) and be supported doing that.
So, the word "multi-tenancy" is often misused in my opinion and it depends what the source understands under multi-tenancy, on which level that would be (VM wise or SAP software wise or ...).
If you see multi-tenancy as running both ERP and CRM on a single HANA database then I cannot answer the question as I don't know how much progress was made to make this happen. This is still the vision where things need to move towards, running a single HANA database with all your SAP applications plugged into it.
2. Also, we found that 'HANA supports the multi-tenancy that built in the application (e.g. CRM) itself'.
I don't have the context here and the sentence sounds "strange" but if I had to guess, I would guess they mean that some products can run together. For example ERP sidecar scenario + BW can run on a single HANA database (thus instance).
These combinations are described in SAP notes.

SharePoint 2013 Multi-tenant Feature Packs

I have not seen any information in regards to multi-tenancy feature packs for SharePoint 2013. Currently it seems, with the new end user licencing, when you install the Enterprise bits you can license a user for either Standard or Enterprise but not
Foundation. In SharePoint 2010 you could use the Enterprise bits then create defined feature packs to give a site collection Foundation, Standard or Enterprise features. Do updated defined feature packs exist for 2013?
There is mention of them here http://www.harbar.net/articles/sp2013mt.aspx
"Feature Packs provide the ability to constrain the Features available for a given tenant. The fundamental capability
isn’t changed in any way here, but of course the Features in the product have. Thus the old Feature Pack definitions for SKUs are no longer valid. A new set of feature pack definitions are required encompassing all of the new Features in SharePoint 2013."
But nothing else anywhere on the net, anyone have any ideas?

Hi all,
I thought I'd give an update. I too have worked through official channels and I believe I'm making progress but not a solution unfortunately. When you run Get-SPFeature, you get 409 different features. One thing I noticed, was the features
ending with Stapler that Spence didn't add to his foundation features suggests that adding these could be erroneous. This led me to believe that my ignorance in the above message was bliss and that my idea was not going to fly. Take for example
this:
AutohostedAppLicensing
AutohostedAppLicensingStapling
So is AutohostedAppLicensingStapling a Standard or Enterprise Feature, or something internal that should not be added as it gives bad results? What about the others I don't find?
Then I posed the question - what do the ID's with EDU* in them mean? They don't exist in product info - perhaps it's education specific SKU's? Does that expose customers to use SharePoint for Internet Sites without the SKU as we assume Enterprise
would be the baseline for all 409 features and we work our way back?
Or even this - MS Access Services is a feature, yet there are 10 Feature ID's associated with it. With Exchange, there are PS commands that refer to MS Internal only and for O365 use only. What
if the 209 features Microsoft sent me as a descriptor for onprem cannot correlate to the 409 Get-SPFeature ID's I have in my bag that render my farm useless?
I've also done research around the net and it looks like everyone went the inefficient, non-multitenant way - that is, either do foundation and try to compete with O365, or offer dedicated VM farms for clients with Standard or Enterprise installs and centralise
the SQL back-end.
Surely noone has done true multitenant... Have they?
Question. If i provision a client with no -Featurepack ID, do they get nothing or the default which is Enterprise Edition? I'd presume I will get nothing or an error for not specifying a switch but I would have to build another environment to
test.... which brings me to my last point. Based on the way Std and Ent can be enabled for on-prem customers on an individual basis and I installed Standard edition on its own VM then enumerated the Get-SPFeature cmdlet, surely I'd see all the features,
not just the standard edition install features. right? If not then I'll build it, enumerate the list and my 2013 Feature pack is sorted.
The biggest fear I have on this is going it alone and if I stuff up, having a non-compliant licensing solution for every user on the system and MS banging down my door for noncompliance on something they didn't provide guidance on in the first place.

Need help with the new Multi-cam feature in CC

Hi,
I'm trying to use the Multi-cam feature in CC and have a few questions, so would be happy with help/advice for any of the issues below. The platform is Windows 7 Pro 64bit.
The first question is what am I doing wrong? This question relates to the fact I'm trying to use Multi-cam and encountering a lot of frustrating glitches, as sometimes it seems to work and at others it doesn't.
The video I'm trying to edit comes from a dance show so I created a sequence called Act 1. I then highlighted the six clips of Act 1 with Cam 01 at the top, as I wanted the audio from this clip and made a Multi-cam feature using the audio synch. I dragged it to the sequence, set the prog window to Multi-cam and was amazed at how well it had synchronised all clips, as I could see all six clips with great audio synch from Cam 01. So far so good and after thinking how brilliant it was, things went downhill from there
I started by using ripple delete to drag to the start of Act one and then tried editing with Multi-cam. That's where I encountered the first problem, as sometimes it seemed to toggle between cams but didn't put edit points in and the selected cam had a yellow border and not a red one. At other times it inserted edit points when I changed cams and the selected cam has a red border. I can't work out what I'm doing, or not doing for this to happen. Can anyone help please?
The second question is how do I cut audio and video at exactly the same point, as I want to edit out pauses in between the different elements of the actual dance show. When I use the razor tool in Multi-cam it only cuts the video. I tried highliting audio and video using shift, but to no effect. If it matters audio and video are shown as linked when I right click. I thought I might get it to work if I revealed all original clips within the MC nest using the technique shown in "Adobe Learn." This was Ctrl double click, but it resulted in the third problem.
When I tried Ctrl double click I ended up with only Cam 02 showing in the V2 track and after some frustrating attempts at resolving this issue I decided to start all over again. I deleted the PP project and created a new one, importing everything again. I followed exactly the same procedure as I originally did to create a Multi-cam nest, but when I dragged it to the new sequence I saw Cam 02 in V2 of the sequence, which is the same as it was before I deleted the original project. Premiere Pro seems to have annoyingly remembered the actions that went wrong, so please can anyone tell me how to tell Premiere Pro not to do this?
Thanks if anyone can help me on any of the issues.

In Premiere Pro, multi-camera is accomplished by nesting a sequence. There's a new, more automated way of doing this in CC. View the steps here: http://blogs.adobe.com/premierepro/2013/04/a-quick-walkthrough-of-editing-a-multi-camera-s equence-with-clips-synchronized-by-audio.html
HOWEVER, you must be warned that multi-cam in CC is currently broken. A patch is in the works, but until it is released you should not use multi-cam in CC.

Multi-tenancy for a seperate business unit

Apparently, we can't do multi-tenancy with SCSM 2012 R2 (see link below). We'd like setup SCSM for one of our business units, but we don't want any of their stuff mingling with our IT stuff. It looks like we'll have to create a
new Management Group. Is it possible to create a new Management Group on the same server as our current IT Management Group, or do we need a new server ?
https://social.technet.microsoft.com/Forums/systemcenter/en-US/0891a803-c5f6-4e21-9958-ea4adc2381c6/scsm-2012-multitenant-architecture
Also, to save some work, is there a way to export settings (eg. for the connectors) from our current IT Management Group to the new Management Group ?
Thanks

Hi,
as per Microsoft Definition "The Service Manager management server and its associated Service Manager database make up a Service Manager management group." This means, that if you need additional Service Manager Management Groups, you have to install
additional servers.
I find it very handy, that you can leverage a single data warehouse Management Group and centralize your reporting if you register your many Service Manager management groups with a single data warehouse management group:
"In your enterprise, you might create multiple Service Manager management groups. You can centralize reporting for multiple Service Manager management groups by registering multiple Service Manager management groups with a single data warehouse management
group."
Source:
Planning for System Center 2012 - Service Manager Deployment
https://technet.microsoft.com/en-us/library/hh519640.aspx
About exporting your settings...They should be stored in management packs, which you can import in the new management group. About the connectors - you have to recreate them in the new environment and this shouldn't be a big administrative effort. It will
take probably not more than 30 Minutes to recreate all possible connectors.
I hope I could help you further.

Stoyan

Sharepoint 2013 setup with multi tenancy

Hi,
Anybody have a proper guidance on how to setup SP 2013 with multi tenancy ? And aslo it should be with hosting mode, because we are the big hoster.
We need hosting SP 2013 with multi tenancy.
Thanks in advance.

Hi,
I have made setup a SharePoint 2013 multi-tenancy.
I have some issues regarding SharePoint 2013. I have created one SharePoint site collection. I've designated myself as a site administrator. I'm able to login to the new site collection, however when I try to add people from my created SharePoint
site collection. It shows me "No results found".
But In central administration, I can add people as well as can give the permissions.
Any suggestions, How can I troubleshoot ?
Thanks in Advance.

Is the multi shoots feature for the new iso 7 camera supports iphone 5 or just the 5S

Is the multi shoots feature for the new iso 7 camera supports iphone 5 or just the 5S

The 10 fps burst mode will only be available on the iPhone 5s. I believe all of the other features for sharpening photos from multiple shots are iPhone 5s only as well.

What happened to the multi-vlan feature?

I've read cisco documentation that discusses the multi-vlan feature on the 2900 XL series, but not for the 2950s. Is this functionality provided in a different way on the 2950s?

The short answer is yes, via trunking.
The multi-vlan feature was originally supported on the early 2900XL hardware since the asics used at the time did not support ISL or dot1q encapsulation. When the updated 2900XL and the 3500XL were released they had asics that did support ISL and dot1q encapsulation and so multi-vlan support was no longer required. A decision was made to keep the multi-vlan feature available for these platforms... I assume... so that customers with a mix of 'old' and 'new' hardware could configure them the same.
When the 2950 and 3550 were released a decision was made to no longer support the multi-vlan feature since the hardware of both already supported either ISL and dot1q (3550) or dot1q (2950).
HTH,
Bobby

VPD - suitable for multi-tenancy?

Would it be a bastardization of the intended capabilities of Oracle virtual private DB to try to use them to convert a single tenacy application into multi-tenancy? The idea would be that there not a 1:1 mapping of schemas to customer, but rather a single schema where all customers' data is retained. Bad idea?

That would be perfectly in keeping with the intended use of VPD. That's one of the primary reasons for that functionality to exist.

Multi tenancy ACS

Hello,
Is it possible for Cisco ACS 5.4 (or any other version) to work in a multi-tenancy environment?
I would like to have two ACS servers, one primary, one secondary, with completely different routing (but obviously keep access to each other for replication).
This would allow me to have centralised management of ACS, but I need ACS to accept client devices request coming from potentially overlapping IP addresses.
When I try on ACS5.4, it simply complains the second client device's IP clashes with the first.
Is it possible?
Steve.

One definition of Multi-tenancy is an application and database that is built to hold multiple customer data in 1 database. Some apps are written such that only 1 client can use that database, going to a multi-tenancy model requires a complete database redesign and application redesign. How to build? Thats a huge question. My consulting rate is...... Thats a question that is almost impossible to answer without knowing the specifics of what you are trying to do, even then trying to answer it in a forum is almost impossible also.

Multi tenancy with schema per tenant

Hello,
I am tryign to run multi tenancy with schema per tenant. It seems to work good when tenant ID is set in XML as a property for persistance unit.
But I need to set tenant in code. Is that possible? How?
I found this article:
codecrafters.blogspot.it/2013/03/multi-tenant-cloud-applications-with.html
So I tried to set it in doBegin method in custom transaction manager. But that doesn't work. I guess relation descriptors aren't updated right.
I could provide more info with exception stack also but first... have I pick the right approach?
Thanks!

UPDATE 26.6.2015: This isn't completelly right solution. Read also comments below or go to my article at http://www.mafospace.com/articles/multi-tenancy-with-eclipselink-and-inherited-entities
I've solved it finally. Maybe it will be helpful for someone. I've done that in similar way as described in article I linked in first post. Through custom transaction manager.
import org.eclipse.persistence.config.PersistenceUnitProperties;
import org.eclipse.persistence.internal.jpa.EntityManagerImpl;
import org.eclipse.persistence.sessions.coordination.MetadataRefreshListener;
import org.eclipse.persistence.sessions.server.ServerSession;
import org.springframework.orm.jpa.JpaTransactionManager;
import sk.bantip.hotel.server.security.SecurityHelper;
import javax.persistence.EntityManager;
import java.util.HashMap;
import java.util.Map;
public class MultiTenantJpaTransactionManager extends JpaTransactionManager {
* NOTE:
* Maybe it would be also possible to replace existing entityManager in transaction with new but it
* isn't a good idea because of rollback and other problems.
* So when new tenant is required always start new transaction for it.
@Override
protected javax.persistence.EntityManager createEntityManagerForTransaction() {
EntityManager em = super.createEntityManagerForTransaction();
boolean refreshed = false;
String actualTenant = null;
ServerSession ss = ((EntityManagerImpl) em.getDelegate()).getServerSession();
Map sessionProp = ss.getProperties();
actualTenant = (String) sessionProp.get(PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT);
// don't run it if tenant didn't change
// it should be quite faster then
if ((actualTenant == null && SecurityHelper.getActiveTenantSchema() != null) ||
(actualTenant != null && !actualTenant.equals(SecurityHelper.getActiveTenantSchema()))) {
// set new tenant as property for actual session
// while refreshing metadata it will be used from actual session for new session
sessionProp.put(PersistenceUnitProperties.MULTITENANT_PROPERTY_DEFAULT, SecurityHelper.getActiveTenantSchema());
MetadataRefreshListener mrl = ((EntityManagerImpl) em.getDelegate()).getServerSession().getRefreshMetadataListener();
// metadata refresh listener is empty if it was already run for actual transaction (same entity manager)
// because it is placed in createEntityManagerForTransaction now this shouldn't happen but to be sure...
if (mrl != null) {
Map<String, Object> prop = new HashMap<String, Object>();
// metadata will be refreshed for next created entity manager
mrl.triggerMetadataRefresh(prop);
refreshed = true;
// if metadata for "old" entity manager wasn't refreshed we don't need to create a new one
return refreshed ? super.createEntityManagerForTransaction() : em;
Everything seems to work except inheritance with strategy type JOINED now. To fix that use customizer.
import org.eclipse.persistence.annotations.TenantTableDiscriminatorType;
import org.eclipse.persistence.config.DescriptorCustomizer;
import org.eclipse.persistence.descriptors.ClassDescriptor;
import org.eclipse.persistence.descriptors.TablePerMultitenantPolicy;
* For some reason when using table per tenant with schema discriminator isn't set good for child
* entities with inheritance JOINED strategy. It stay as SUFFIX and therefore it doesn't work.
public class InheritanceJoinedMTFixCustomizer implements DescriptorCustomizer {
@Override
public void customize(ClassDescriptor descriptor) throws Exception {
// set discriminator to SCHEMA
((TablePerMultitenantPolicy) descriptor.getMultitenantPolicy())
.setTenantTableDiscriminatorType(TenantTableDiscriminatorType.SCHEMA);
And in child entities use it like this:
@Customizer(InheritanceJoinedMTFixCustomizer.class)
public class Person extends Contact {

How does the servlet implement the multi-thread feature?

There is only one instance of every servlet in one wep application.
When several clients invoke the doPost() method of the same servlet,the servlet can process their request respectively.
So there much multi threads of one servelt.
But the Servlet doesn't implement the Runnable interface of extends the Thread class.
I wan't to know,how does the servlet/servlet container implement the multi-thread feature?

Hi johnnylzb
There is only one servlet instance existing.
(assuming u have <load-on-startup>1</load-on-startup>)
The server creates a thread for every request ..
and all the threads access the same servlet instance.
For this its not necessary for the Servlet to extend Thread or Runnable.
hope this helps

Multi window feature has gone

I updated the firefox mobile for Android and as a consequence firefox icon was removed from my galaxy note 2 multi window tray. Is there any method to get this feature back? If not can I reinstall a firefox version that supports this feature?
Note: I've already tried Firefox 21.0 BETA version. There is no change.

I've just found out that the developers have removed this because an user reported some icons that appear on screen can block some pixels if application. However, that is ridiculous to remove it. If so , the user must turn multi window feature off. There was no need to remove it.

Learning Solution and Multi-tenancy

Hello All,
Does SAP Learning Solution support multi-tenancy/SaaS models?

Hi,
I would describe Learning Solution to be built upon the TEM.
Learning solution provides a web interface where an employee can prebook/book/cancel for the courses available. Also the approvals if required can take place.
Learning Solution offers E-learning facility that is, web based training courses through its interface.
The concept of prebook/book/cancel and followup activities is same as TEM but the transactions in ECC are different PSV1 is LSO_PSV1 similarly PSV2 is LSO_PSV2 and so on.
So if you are going for ESS and Portal and want your employee book courses from web interface then go for learning solution as learning solution also gives e-learning as well.
Incase of TEM if you want the administrator is only responsible for the training activities then go for TEM,
But learning solution offers both administrative tasks through LSO* transactions as well as online booking.
So i suggest you go for Learning solution which by default is present in the new versions of SAP ECC.
Regards,
Divya
