Activity Stream in the Webcenter

Hi All,
I am working on web center portlet JHeadstart application there is a requirement like when i add any entry in that table the same time Activity stream should get updated how to achieve this task.
Can you please help me.
Thanks.

Hi.
Update: Sorry I probably mistake saying Materialized View for your requirement.
You have to do some PL/SQL, triggers and update your Activity Stream table.
Regards.

Hi,
Creating package doesn't mean it will install the product,
You will need to install the package now. Please follow the instructions mentioned in the below articles

Activity stream in CC desktop manager is not updated

Hello, the activity stream on the Home panel of the Adobe CC desktop manager is not updated. I'm logged, I sync, I reinstalled the Adobe CC manager. I use the same Adobe CC account on another MacBookPro OS X 10.10 and the activity stream in the Home panel is fine.
MacBookAir OSX 10.10.1, Adobe CC (2014), no firewall

I'm having the opposite problem. All those listed in the screen shot as "Install" have been installed.
Deleting OPM.db and downloading and installing CreativeCloudInstaller.dmg did not fix the issue.
Do I really need to delete all of my installed apps and starting from scratch?

Apps are listed as "Install" when they've already been installed

Setting advanced query on Activity Stream

Hi
I'm using Publisher and Activity Stream taskflows together in a page and I need to differenciate when an uploaded document comes from publisher or not.
By setting an advanced query at Activity Stream Content Presenter, for example: AE.ACTIVITY_TYPE NOT IN (\'create-document\') hide all the new documents uploaded by users on Content Server regardless of the location. That expression doesn't differentiate between documents uploaded to a personal folder or a public one.
I need to hide on the activity stream all the new documents uploaded under /PersonalSpaces folder and subfolders in Content Server. So, documents uploaded using Publisher would appear because are stored under /WebCenterSpaces/my_folder_space/
Documentation is quite poor.
Please help.
Regards

So,
For Case 1 : When Process B is getting executed in a separate Thread and Transaction , then when process A is getting rolled back why B is also getting rolled back as it's in different thread althgether.
3) For Case2 : Please clear my following understanding :
When we set the value to 'sync' for process B, then B will act like a synchronous process(ideally it Async), and will get committed after the it's execution. Because of this, even if A is getting rolled back, B will not get rolledback because it is already committed. For case 1:
By calling process B, an invocation message is being insert into the dehydration store. That causes process B to be created as a new thread/transaction.
When you perform rollback->the new transaction that was made following the new thread, is being rollback among the rest of your process transaction(the rollback causes the message not to be save and for that you can't see new instance).
For case 2:
By calling process B, only a new transaction is being creating, and invocation message is not being insert into the dehydration store.
So actualy, you have 1 thread and 2 transactions, and you are telling your process(thread) to rollback only the current transaction and not the new one (process A not owns the new transaction).
2) You mentioned if we are calling Process B with No Rollback. How to call B with No Rollback? Is there any property like that? It was just an example. Forget about it.
I hope it answered you questions...

Unable to publish in the Activity Stream of my portal

Recently I've been working on a Portal Site and in the page of Activity Stream, I couldn't publish anything after I clicked on "publish" button. This problem only happened on that specific space, not other spaces.
Another thing I noticed is: under the "Share Something" box, there were only "Attach: Link". It were missing "File". It should be "Attach: Link | File".
Could someone who knows this issue give me some suggestions? Thank you!!

I figured out a way to fix this with my new Apple TV!
After trying EVERYTHING!...(Trust me, I had tried EVERYTHING!) including restoring Apple TV to the original factory settings....reconiguring in every-which possible way.....
Here's what I did to make it work.
I happened to be in the "Settings" app of my iPhone, where I did something with the calendar settings for iCloud.
There, it prompted me to read the new "Terms & Conditions". I agreed to them and then went directly to my Apple TV and it immediately worked.
This was after WEEKS of trying EVERYTHING!
So the key is to get an Apple device to prompt you with the new "Terms & Conditions". Once you've agreed to it, you should find that Apple TV will let your PhotoStream work again!
Hope that helps!

Input WCM content to Activity Stream Taskflow

Hi I am trying to input the data coming from WCM to Activity Stream task flow. Plan is read the data from WCM using java API and input it to the activity stream task flow. Can some one tell me how can we access this taskflow using Java API. I went through the API ref but couldn't fig out how to use it.
Thank in advance

Hi.
You can use WebCenter API. In case of version 11.1.1.8:http://docs.oracle.com/cd/E29542_01/apirefs.1111/e15995/oracle/webcenter/activitystreaming/package-summary.html
Take a look in the classes ActivityStreamingService and ActivityStreamingServiceFactory
Basically you have to use ActivityStreamingService for posting new updates. How?.
To get the ActivityStreamService:
ActivityStreamingService service = ActivityStreamingServiceFactory.getInstance().getActivityStreamingService();
Fill all parameters requited for method createActivityElement
applicationID - application ID of the activity:
WCApplicationFactory fact = FactoryFinder.getFactory(WCApplicationFactory.class.getCanonicalName());
WCApplication application = fact.getWCApplication();
String applicationID = application.getApplicationName();
scope - the Scope of the activity
ServiceContext.getContext().getScope()
serviceID - the service ID of the activity Depending of the content there are different serviceId:
wiki = oracle.webcenter.wiki
blog = oracle.webcenter.blog
document = oracle.webcenter.doclib
webContent = oracle.webcenter.content
You can use UCMHelper.getServiceID passing the resourceType as argument to calculate it or when retrieving the node with Content Presenter, using #{node.propertyMap['webcenter:serviceid'].value.stringValue} will retrieve corresponding serviceID directly.
activityType - type of the activity Take a look into the API to fill it
actors - list of actors involved in the activity (there must be at least one actor in the activity) Take a look into the API to fill it
objects - list of objects involved in the activity (optional) Take a look into the API to fill it
permission - the permission of the activity Take a look into the API to fill it
activityTime - time when the activity happens Take a look into the API to fill it
Sample taken from activity libraries. Remember replace all the sample variables with how to get ApplicationID, Current Scope, etc... that I share to you
ActivityStreamingService service = ActivityStreamingServiceFactory.getInstance().getActivityStreamingService();
      ActivityActor actor0 = service.createActor(this.actor0DisplayName.toLowerCase());
      ActivityActor actor1 = service.createActor(this.actor1DisplayName.toLowerCase());
      List actors = new ArrayList();
      if ((!this.actor0DisplayName.equals("")) || (!this.actor0DetailURL.equals("")))
        actors.add(actor0);
      if ((!this.actor1DisplayName.equals("")) || (!this.actor1DetailURL.equals("")))
        actors.add(actor1);
      ActivityObjectType objectType = ((JpaActivityStreamingService)service).createObjectType("message");
      ActivityObject object0 = service.createObject("object0", objectType, this.object0DisplayName);
      ActivityObject object1 = service.createObject("object1", objectType, this.object1DisplayName);
      List objects = new ArrayList();
      if ((!this.object0DisplayName.equals("")) || (!this.object0DetailURL.equals("")))
        objects.add(object0);
      if ((!this.object1DisplayName.equals("")) || (!this.object1DetailURL.equals("")))
        objects.add(object1);
      ActivityType activityType = ((JpaActivityStreamingService)service).createActivityType("test");
      activityType.setMessage(this.message);
      ActivityElement activity = service.createActivityElement("customapp", new Scope("test"), "oracle.webcenter.activitystreaming.test", activityType, actors, objects, ActivityPermission.SHARED, new Date());
      service.publish(activity);
    catch (ActivityException e)
      WCServiceViewUtils.getInstance().logAndDisplayError(e);
I hope it helps

Can we bind twitter streaming with web center activity stream.

Our PM suggests us to use Web center activity stream to store the twitter status based on our twitter search filter . To achieve that, it seems that we need to include the activity taskflow ( or data control) in our application and binding the taskflow with our twitter streaming. Is there any approach to achieve that? where can I find more details about using/extending activity stream.

Activity Stream Will Not Load

Hi Guys
I'm having more problems with Adobe's *&¥±∑βΩ%^ing cloud!
Now that's off my chest, I'm using a Dell Precision6700 with a Win7 64bit OS. I've been trying to update AECS6 since last week but it crashes at 50%, with a corrupted file message (I've raised this on the AE forum).
I've tried closing my firewall but no dice, so I thought I'd logout and back into the application manager. First I couldn't logout; "quit" was greyed out but I didn't exit the programme and everytime I reopned the AM I was still in it, even after rebooting. Next I "quit" again but closed down for the evening. This time I did exit the manager. Now when I enter my details I get back into the manager but the activity stream will not load (I just get the little wheel going around) until the screen just closes by itself.
For someone unimpressed by the Cloud in the first place these types of glitches are not winning my heart and mind. Can anyone tell me how I might fix this simply, without having to buy a new laptop?
Regards,
Graham

Photo stream only maintains photos for 30 days. After that they are deleted from photo stream but not from any devices than have already downloaded the photo stream photos. When you enabled photo stream on your new phone you were only able to download photos that fall within this 30 day period as the others are no longer in your photo stream (even though they remain on your other devices).

Activity stream not up to date ?

After upgrading to Lightroom CC on my iMac 27" late 2013 the activity stream in Creative Cloud displays old activity 400 days ago.
I have logged out and in again and still no change.
It is not a problem and everything is working perfect - but if anyone knows why, I´d like to fix it.

Hi Peter,
Thanks for you answer.
In ST22 I can see the error Uncaught_exception, CX_BBP_PD_ABORT. It looks like it terminated in the program SAPLBBP_PDH with main program SAPLBBP_PO_UI_ITS.
If I look at Internal errors in RZ20 I can see the following:
ABORT: FORM CHECK_PARTNER_EXISTENCE SAPLBBP_PDBUP/ FORM
PDBUP_MAINTAIN_ALL SAPLBBP_PDBUP
Sincerely

Activity Streams Issue

The documentation shows a “File” link next to the “Attach” content that no longer shows up on our Space. What could be the reason for this?
Additionally, there seems to be a bug where there is no publishing of anything to the activity stream if that space was configured for “Advanced” role permissions, as is the case with our particular space. Is our only option re-creating it from scratch since once “Advanced” permissions is set you can’t turn them back off?
One idea I had for that was to close the space, export it and then see if we can edit the exported data to remove/change the permissions. Another Demo Space we have space does not have this issue because the permissions were never set to advanced. I was thinking if we export this space we may be able to see the difference and adjust the broken space's export accordingly and re-import it without having to recreate the entire space. Does this sound like a valid solution or is there an easier cleaner approach?

The documentation shows a “File” link next to the “Attach”....Can you perhaps put a link to the documentation because i don't have a clue what you are talking about.
there seems to be a bug where there is no publishing I tried it on my installation and it works probably.
Can you try to create a new group space and set the advanced security and see if its work. Also make sure you do something before you change the settings to see if the AS works in normal conditions.
Also check your user his profile to see if the notifications are on for the different resoruces.

App-V 5 Full Infrastructure Apps take long time to stream to the client

Hi was wondering if anyone has the same issue as i am or knows a fix for this, below is my problem and the troubleshooting i have done.
Overview of problem
App-V 5 apps delivered via App-V 5 full infrastructure take a long time to stream to the client and this means the user has to wait if they try and run an application before it has streamed to the client. Users sometimes have to
wait 2 or 3 minutes for an application to stream and this is about 40 times slower than basic SMB and HTTP transfer tests show the system is capable of (see performance results below).
App-V 4.6 apps delivered via App-V 4.6 full infrastructure and HTTP streaming are fine.
Overview of environment
App-V 5.0 SP1 Full Infrastructure.
App-V servers are running Server 2012 on Hyper-V 3 or ESX 5.1 with 2 x vCPU and 4GB RAM.
SQL servers are a SQL 2012 cluster.
Separate servers for SQL, management, publishing, content and reporting.
Management, Publishing and Content servers have two servers per role and NLB to provide load balancing. So 7 servers (2 x Man, 2 x Pub, 2 x Content, 1 x Reporting)
Two further sites with 2 x Pub and 2 x Content each. All publishing servers pointed at the load balance address for management.
Content delivered via HTTP
Clients are physical desktops and laptops running Windows 7 SP1 x86 and Windows 8 x86
App-V client is 5.0SP1
Clients are pointed at their nearest publishing server NLB via a script which looks up the client IP address and uses PowerShell to configure the publishing server
Content is streamed from the nearest content server NLB by setting the PackageSourceRoot to the nearest content NLB (via the same PowerShell script above).
App-V apps delivered per-user via AD group. One AD group per application. Approximately 200 App-V apps published so far - will eventually reach 400 as we sequence more. About 9000 users.
Analysis performed so far
Servers not heavily loaded. CPU averages 5%. Lots of RAM free. Very low disk IO. Problem also occurs out-of-hours so we are 99.9% certain that server resources are not a cause.
Streaming performance is the same from all 6 content servers and all 3 NLB addresses (tested by changing the value of PackageSourceRoot). Wireshark used to confirm packages are really streaming from the correct location, enforcing
our belief that the problem isn't at the server end (unless all 6 servers are affected).
Streaming via both HTTP and SMB2.1 is approximately the same (tested by changing the value of PackageSourceRoot between http://xxxx and \\server\AppVContent).
Wireshark used to confirm we really are using the protocol we think we are using.
All clients exhibit the same behaviour. Issue reported by many users. 5 test PCs chosen at random at all 3 sites confirmed to have the slow streaming problem.
Slow streaming from both Hyper-V and VMware ESX servers.
Client not heavily loaded.
Affects all App-V apps although it obviously affects the larger ones more.
All App-V apps have a Feature Block 1 setup.
If we copy the ".appv" file from the server to the client via either HTTP or SMB then it's reasonably quick (up to 480Mb/s). So we don't believe the network or servers are at fault. For example:
We can copy a 149MB .appv file via SMB from the content server to the client in 5 seconds.
We copy HTTP download the .appv file from the content server using IE on the client in 5 seconds.
But if you ask the App-V 5 client to fully download the sequence then it takes 2 - 3 minutes.
The App-V 4.6 client takes about 8 - 10 seconds to fully download a similar sized application.
App-V 5 publishing works fine - when a new user logs on they get their list of application straight away, it's just the streaming which is slow.
Once the App-V app has streamed locally it runs fine and with a decent performance.
Looking at a Wireshark trace of the streaming you can see that the slow performance is due to the transfer stopping and starting a lot. You only notice this when you zoom into the performance graph a fair bit.
Each time the HTTP server stops sending traffic, it doesn't start again until the client sends a "TCP Window update". Each "stop" is of a different length, but just taking a few from the middle I get 0.06s, 0.11s,
0.13s wasted etc.
I can see that it's the client stopping the transfer by reducing its advertised TCP Window Size. I'll provide an example:
Server sends 9 x 1514 bytes. Client responds with an ACK and a Window size of 54016 bytes (256x211)
Server sends 11 x 1514 bytes. Client responds with an ACK and a Window size of 37888 bytes (256x148)
Server sends 10 x 1514 bytes. Client responds with an ACK and a Window size of 23296 bytes (256x91)
Server sends 15 x 1514 bytes. Client responds with an ACK and a Window size of 1280 bytes (5 x 256)
Server stops sending (I'm guessing because the client advertised Window size was less than a single packet's worth of bytes)
<0.1 seconds passes>
Client sends a "TCP Window Update" re-advertising a TCP window size of 65536 (256x256).
Server starts transmitting again
So the way I see this is that the App-V 5 client is controlling the transfer speed by utilising TCP Window flow control. The trace was taken at the client end so there's no room for anything on the network to be fiddling with flow
control (and we've confirmed there are no traffic shapers in the loop).
We've also tried streaming directly from the local client by copying some App-V 5 apps down to the client, creating a SMB share on the client and changing PackageSourceRoot to \\localhost\AppVContent (i.e. so we are streaming directly
from the client to the client - to remove the network from the equation) and there is only an improvement of 5 to 10 seconds. So we know it's nothing to do with the network or the servers.
We've tried turning off TCP auto-tuning on the client with:
netsh interface tcp set global autotuninglevel=disabled
and turning off TCP chimney offloading (which is off anyway because the NIC doesn't support it and Netstat -t output shows "InHost" for offload state for all connections) with:
netsh int tcp set global chimney=disabled
and nothing has improved.
So we've now focussed on the extraction of the .appv (ZIP) file on the client.
Using Windows Explorer it takes 75 seconds to extract the ZIP file
Using 7ZIP it takes 9 seconds to extract the ZIP file
Yeah we've always known that the Explorer ZIP engine is terrible. That's why we use 7ZIP or WinRAR on our clients.
So we've started to wonder if the problem with the slow App-V 5 streaming is because the client is downloading the .appv file and extracting it as it goes along in a single thread. If the App-V 5 client is using the same terrible
ZIP engine that Explorer does then that would explain the slow performance. The "download" appears to take a long time because the client is using TCP flow control to slow the transfer since it's extracting the .appv file using a very slow ZIP engine
and it's all in a single thread.

Guys,
Just wanted to give you a brief update basically close this thread as Answered.
We had submitted 4 App-V 5 Bugs to Microsoft and these were reproducible and an explanation was given on work around to them. Microsoft
sent down a App-v developer to have a look at our problems. They said they will try and include the Bug fixes in SP2 which should be out in a few weeks or they will definitely be included in SP3.
In regards to the slow streaming it all came down to the Disk IO.
We found that you could simply enable "Turn off
Windows write-cache buffer flushing on the device", then start streaming the app and then disable "Turn
off Windows write-cache buffer flushing on the device" immediately after
(we don't want to leave it on) and that basically fixed the issue.
But a normal user would not have permissions to do
this, so a code was written to enable and disable this option.
Apology for not going in detail, like my opening thread, its very late.
but if you would like a detailed analysis please message me.
I would like to Thank the Talented Consultant who designed and implemented are App-V infrastructure who found the bugs and created all
the work around and who also emailed the detailed analysis of the problems to Microsoft that got them interested.
Simon Bond from Ultima Business Solutions.
Thank you

My storage is mostly full of a category labeled "other." I'm out of memory to the extent that it won't even allow me to update apps. I have moved all photos over to my computer and my music streams through the cloud. Any advice on how to fix this problem?
