What method are you using. I am looking at using the single schema with the TenantGUID column.

Can you give me the URL to access that document?

Anyone using Multi plexing to solve RMI firewall problem?

Hello,
I read in the RMI protocol spec about Rmi's multiplexing protocol (http://java.sun.com/j2se/1.3/docs/guide/rmi/spec/rmi-protocol7.html)
which states:
The purpose of multiplexing is to provide a model where two endpoints can each open multiple full duplex connections to the other endpoint in an environment where only one of the endpoints is able to open such a bidirectional connection using some other facility.
However i still have not found how to do this using the RMI api provided within Java. I have read numerous posts saying that you CANNOT using the multiplexing protocol, I have read posts which say that you should not allow the client to create a server socket which will force the client to use the multiplexing protocol over an existing socket.
My main concern is the product i am developing will be used across firewalls, where we are able to create connections from our server to our client, but the firewall disallows the opposite, and our IT department WILL NOT open access on known ports. Thusly our only option is to use the multiplexing protocol if it does in fact exist/work.
If anyone has any experience using the multiplexing protocol in a firewall environment please post your experience here.
Thanks,
Dan

Hi Dan,
I have had a lot of success using proxies to work around firewalled clients. I host a free software project at java.net dedicated to spontaneously linking Virtual Machines using RMI.
https://cajo.dev.java.net
It uses two classes, ClientProxy & ItemProxy, to implement the protocol.
More detailed information about this can be found here.
Best wishes,
John

Has anyone used the Black-Magic Design Multi Bridge?

Currently I have a Black Magic Multi Bridge Extreme. It works, but there seems to be an issue with a very (hot) running unit. The fan is running (very loud I might add), and does seem to cool down the unit, just a bit. If there is anyone using this or simular unit, could you provide some feed back. Thanks

I've got a new Mac Mini running HDMI to a 40" Sony Bravia Flat Panel... works fine.
I do have an issue when I turn on the TV and wake the Mini from sleep... the screen stays really dim. Not sure if it's the Mini or the TV that's the issue. After the Mini is fully on... a power cycle of the TV seems to bring everything back to normal.
Brett, I have the same problem when I bring the mac out of sleep mode. Have you managed to find out why we have to switch the TV Off then On again to get the picture? Or another solution? Very annoying when you have 1000's $ worth of equipment but the solution is still "Have you tried switching it Off and On again" (All due respects to the "IT CROWD").

Has anyone used Audacity to create a Podcast on a PC and then make it available on itunes?

Has anyone used Audacity to create a Podcast on a PC and then make it available on itunes? If you have used Audacity is it a good program to use? Any tips or suggestions?

Almost certainly. You can use any program which does what you want: the end product has to be an .mp3 or .m4a file. After that it's a question of making the feed, either writing it yourself or more likely using a program or online service.
Audacity is a useful program, and free, and you can certainly do the sort of things you need to make a podcast. I prefer Amadeus Pro, which costs $59.99 and has recently been updated with better multi-track facilities: I always fled that Audacity was awkward to use by comparison and occasionally flaky, but we're probably splitting hairs here: it would certainly be a good place to start.

Can you use Multi Factor Authentication server with Central NPS and RD Gateway?

Hi,
Does anyone have any experience getting the Azure Multi-Factor Authentication (MFA) on-premise server, working with a Remote Desktop Gateway server, and a centralised NPS server? I can get a solution whereby a user can get the second token (phone call/sms
etc.) but the connection never gets established. It looks like its looping as it repeats the phone call/text for a second time but again no connection. I can’t figure out why.
All the blogs are very vague as to whether you can combine a new MFA NPS connection policy with an existing username/group membership NPS policy on a centralised NPS server (with RAP/CAP policies).
I need to understand whether we can combine both an MFA Radius policy with a Username/Password plus group membership NPS policy together to achieve two factor authentication.
Do you have the Remote Desktop Gateway Server connect to the Central NPS server and then the NPS server use the MFA server as its proxy server? In effect turning the NPS server into a proxy Radius server?
Or do you configure the Remote Desktop Gateway server to use the MFA server as the proxy Radius server, and configure the MFA server to send on Radius requests to the central NPS server?
Or either of these scenarios not supported and you can only use the MFA server as the only Radius server in the auth. process? (bypassing NPS policies?)
Thanks if someone can assist,
I’ve been using these blogs but to no successful effect:

Hi Michael,
Thank you for posting in Windows Server Forum.
After going through your description, I can say that we can use MFA server with central NPS and RD Gateway. Also the link which you have provided points the step to apply. In addition you can refer below article.

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!
Martin

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 {

Can't use multi-touch in macbook air on windows 7

i just install windows 7 via bootcamp and install the bootcamp windows support.
everythng seems fine, but the trackpad....
I can use scroll up and down, but i can't tap to click..
and i can't find the bootcamp in windows 7 start manual.
anyone can help me?

A Chrome extension is out which enable Bootcampers to swipe back/forth with two fingers for pages. You can get it here:
https://chrome.google.com/webstore/detail/mgegfjnccpnkdppohmfgnjalkediapkc
Or search for it yourself:
Swipe Gesture
In google addon store.
All credits goes to antimatter15.com for creating this. It's still at an early stage, but very useful indeed. And as seeing that swiping back/forth is one of the most used multi touch features (at least to my experience) this addon is a godsend. Also has no problem with people running virtual machines, as the addon can simply be turned off.

IPad Mini Freezes when close an app using Multi Gesture.

Hello everyone,
I'm not sure if I'm the only one who experience this unusual bug. Since I update my iPad Mini to iOS7 (now it's 7.0.3), whenever I close an app using multi gesture, it freezes. It happens very frequent, in a ratio of 3 out of 5.
Does anyone experience the same issue? If so, is there any way to fix it? Or I will have to wait for Apple to patch up?
Thank you!

Go to settings>icloud>storage and back up>back up
after that preform a restore by going to
general>reset>erase all content and settings
this will delete everything except the enabled stuff on icloud.
You can view whats enabled by going to icloud in settings.

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 On premise Multi-Tenancy vs full SharePoint

Hi,
We have requirements coming in from joint ventures who need their own site collections/sites.
Rather than trying to implement them on our current full Enterprise SharePoint environment we would setup a seperate SharePoint deployment in multi-tenancy mode with partitioned service applications.
Before I offer this up as an option I need to let them know if there are any limitations to a multi-tenant environment over the full versions. I have seen reference to PerformancePoint not being available and it being harder to migrate to O365 in the
future if needed however I have not found a definitive list.
Does anyone know where I can find a list of the limitations (if one exists!)?
Thanks,
Mark

There is no specific list of limitations in one concise spot. But if you read Spence Harbar's articles on Multi-tenancy (for 2010 and 2013) you will find lists of things that don't work in multi-tenancy. For example, there are several services
like the Visio graphics service that don't support partitioning of their databases and are therefore a problem for multi-tenancy. As you mentioned PerformancePoint is another one. Read both articles and you should be able to compile a list of what
you need to know.

Is anyone using testing seeing compiler lock-ups? [SOLVED]

As the title says, is anyone using testing seeing compiler lock-ups? I've been seeing them for about two or three days. Sometimes the system will hang for a few seconds at "Starting make" with 100% CPU usage, then will continue normally. Other times it will stop in the middle of compiling and CPU usage will drop to 0. Also, I've been seeing small hang ups with patches. Maybe four or five seconds when simple patches are being applied. Bringing MAKEFLAGS down to the default 2 from 3 seems to help a tiny bit.

fakeroot would put it in the right time frame. I linked to your bug report Anarconda as it seems like the same problem. As always if anyone has anything to add, please do:

Is anyone using the Calendar Server to send external invites?

Is anyone using the Calendar Server to send external invites?
We have a Mountain Lion server running DNS, Open Directory, File Sharing and VPN. We have recently stood up the Calendar server and it is working very well. Internal invites work fine and are instantaneous to computer, iPhone, iPad. We have the ports working so that calendar items created outside the network work fine as well. Only problem is we cannot invite anyone with an external e-mail address. Each time we do the Calendar Error Log populates with:
2013-04-15 13:11:03-0500 [-] [mailgateway] 2013-04-15 13:11:03-0500 [Uninitialized] SMTP Client retrying server. Retry: 5

We have set up an internal e-mail address. I have confined that it works fine. I have tried more than one internal account. I have also verified the settings through the command line by typing "sudo serveradmin settings calendar" The iMIP sending and receiving information is correct. There is no authentication type setting listed in the command line output even though there's a place to choose it in the Enable invitations by email - Edit button on the third screen. No matter what I choose it goes back to "login" and still doesn't work.
The command line settings mention a port number 62310 as being the MailGatewayPort but opening that port on the network's firewall makes no difference. As I said external set up works fine from Mac/iPhone/iPad and push notification works fine as well.
Is anyone using this functionality?

I'm sorry. I forgot to add Mail to the list of services. I AM using mail on that server. Here's the iMIP portion of my settings output from Terminal.
calendar:Scheduling:iMIP:Sending:Server = "boardwalkserver.kuhnwitt.com"
calendar:Scheduling:iMIP:Sending:UseSSL = yes
calendar:Scheduling:iMIP:Sending:Username = "calendarserver"
calendar:Scheduling:iMIP:Sending:Address = "[email protected]"
calendar:Scheduling:iMIP:Sending:Password = "password"
calendar:Scheduling:iMIP:Sending:Port = 465
calendar:Scheduling:iMIP:Enabled = yes
calendar:Scheduling:iMIP:MailGatewayPort = 62310
calendar:Scheduling:iMIP:Receiving:Server = "boardwalkserver.kuhnwitt.com"
calendar:Scheduling:iMIP:Receiving:UseSSL = yes
calendar:Scheduling:iMIP:Receiving:Username = "calendarserver"
calendar:Scheduling:iMIP:Receiving:PollingSeconds = 30
calendar:Scheduling:iMIP:Receiving:Type = "imap"
calendar:Scheduling:iMIP:Receiving:Password = "password"
calendar:Scheduling:iMIP:Receiving:Port = 993
calendar:Scheduling:iMIP:AddressPatterns:_array_index:0 = "mailto:.*"
calendar:Scheduling:iMIP:MailGatewayServer = "localhost"
So Add mail to the services being used. Since Calendar is running on the mail server one would assume that it could communicate with it fairly easily.
