• Pay in the future should make you think in the present

  - by BuckWoody

  Distributed Computing - and more importantly “-as-a-Service” models of computing have a different cost model. This is something that sounds obvious on the surface but it’s often forgotten during the design and coding phase of a project. In on-premises computing, we’re used to purchasing a server and all of the hardware infrastructure and software licenses needed not only for one project, but several. This is an up-front or “sunk” cost that we consume by running code the organization needs to perform its function. Using a direct connection over wires you’ve already paid for, we don’t often have to think about bandwidth, hits on the data store or the amount of compute we use - we just know more is better. In a pay-as-you-go model, however, each of these architecture decisions has a potential cost impact. The amount of data you store, the number of times you access it, and the amount you send back all come with a charge. The offset is that you don’t buy anything at all up-front, so that sunk cost is freed up. And financial professionals know that money now is worth more than money later. Saving that up-front cost allows you to invest it in other things. It’s not just that you’re using things that now cost money - it’s that the design itself in distributed computing has a cost impact. That can be a really good thing, such as when you dynamically add capacity for paying customers. If you can tie back the cost of a series of clicks to what a user will pay to do so, you can set a profit margin that is easy to track. Here’s a case in point: Assume you are using a large instance in Windows Azure to compute some data that you retrieve from a SQL Azure database. If you don’t monitor the path of the application, you may not know what you are really using. Since you’re paying by the size of the instance, it’s best to maximize it all the time. Recently I evaluated just this situation, and found that downsizing the instance and adding another one where needed, adding a caching function to the application, moving part of the data into Windows Azure tables not only increased the speed of the application, but reduced the cost and more closely tied the cost to the profit. The key is this: from the very outset - the design - make sure you include metrics to measure for the cost/performance (sometimes these are the same) for your application. Windows Azure opens up awesome new ways of doing things, so make sure you study distributed systems architecture before you try and force in the application design you have on premises into your new application structure.

• Reusing Web Forms across BPM Roles

  - by Mona Rakibe

  Recently Varsha(another BPM Product Manager) approached me with a requirement where she wanted to reuse same Web Form for different task activity.We both knew this is easily achievable.The human task outcomes can differ to distinguish the submission based on roles.Her requirement was slightly more than this, she wanted to hide some data based on the logged in user. If you have worked on Web Form rules, dynamically showing and hiding data is common requirement and easily achievable using Form Rules. In this case the challenge was accessing BPM role inside the Web Form. Although, will be addressing this requirement in future release she wanted a immediate solution(Aha, after all customers are not the only one's who can not wait). Thankfully we managed to come-up with a solution and I hope this will be helpful to larger audience. Solution has 3 steps : Step 1: We added a hidden attribute in our form (Role). The purpose of this attribute is just to store the current logged in user's role and we pass the value during data association. Step 2 : In your data association step, pass the role value based on the Swimlane Step 3 : Now use this hidden attribute value in your Web Form rule for dynamic behavior Detailed steps and sample can be downloaded from Java.net.

• Using the @ in SQL Azure Connections

  - by BuckWoody

  The other day I was working with a client on an application they were changing to a hybrid architecture – some data on-premise and other data in SQL Azure and Windows Azure Blob storage. I had them make a couple of corrections - the first was that all communications to SQL Azure need to be encrypted. It’s a simple addition to the connection string, depending on the library you use. Which brought up another interesting point. They had been using something that looked like this, using the .NET provider: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=LoginName;Password=myPassword; Trusted_Connection=False;Encrypt=True; This includes most of the formatting needed for SQL Azure. It specifies TCP as the transport mechanism, the database name is included, Trusted_Connection is off, and encryption is on. But it needed one more change: Server=tcp:[serverName].database.windows.net;Database=myDataBase; User ID=[LoginName]@[serverName];Password=myPassword; Trusted_Connection=False;Encrypt=True; Notice the difference? It’s the User ID parameter. It includes the @ symbol and the name of the server – not the whole DNS name, just the server name itself. The developers were a bit surprised, since it had been working with the first format that just used the user name. Why did both work, and why is one better than the other? It has to do with the connection library you use. For most libraries, the user name is enough. But for some libraries (subject to change so I don’t list them here) the server name parameter isn’t sent in the way the load balancer understands, so you need to include the server name right in the login, so the system can parse it correctly. Keep in mind, the string limit for that is 128 characters – so take the @ symbol and the server name into consideration for user names. The user connection info is detailed here: http://msdn.microsoft.com/en-us/library/ee336268.aspx Upshot? Include the @servername on your connection string just to be safe. And plan for that extra space…

• Capgemini Global Business Process Management Report

  - by JuergenKress

  Welcome to the Capgemini Global Business Process Management (BPM) Report. This report is an exploration of key trends in BPM as seen by CXOs across a broad selection of sectors and geographies. BPM is perhaps at a tipping point - it’s certainly at an exciting stage in its evolution. As both an engineer and an Operational Research practitioner in my early career, and subsequently as a consultant, I have seen BPM through its development over the last 26 years. BPM has its roots in management practices such as Total Quality Management, Business Process Reengineering & Model Based Development; but the advent of the new generation of sophisticated modelling and process execution technologies has greatly enhanced BPM’s power to truly transform businesses. This has created one of the most rapidly growing and attractive market sectors for both services and technology. We see BPM as a critical management discipline that when executed against clear, cross organizational business objectives, can deliver exceptional value to that organization. However, we also see that the potential for BPM is not well understood. Our decision to conduct this global survey stemmed from discussions with our clients. We sought to gain a better impression of their understanding of BPM, how they measure its value, and how far it is prioritized within their Business and Technology Transformation efforts. This research confirms our belief that BPM needs to be a jointly owned Business and IT discipline. It also demonstrates that it is starting to gain significant traction in the market and investments are starting to pay dividends to the early adopters. At Capgemini we are being asked by our clients to help them simplify and improve their business models and the technology that supports them and we are already seeing BPM become an integral and key part of this proposition. Business Process Management is becoming ever more relevant to both large and small organizations in the current economic climate. At a time when many different market sectors are facing slow revenue growth, customer churn and increased pressures on costs, BPM becomes a critical weapon in the battle for efficiency and effectiveness in processes. Furthermore, in a challenging and changing business environment that is characterized by uncertainty, it allows organizations to adapt, be more agile and fleet of foot. Capgemini is seeing strong demand for BPM services in markets such as the USA, the UK, the Netherlands and France; and there are clear signs of increased interest in other geographies such as, Germany, Sweden, Spain, Italy and Australia. In sector terms, the financial services industry has led the way in BPM adoption over the recent past, driven by increased focus on customer- centricity and regulatory compliance. Other sectors, public sector, utilities, telco, retail and manufacturing are now not only catching up, but are starting o use BPM in new ways to create new business models to serve customers and outsmart the competition. The research findings also show however that this is a complex landscape, and we are not seeing adoption of BPM in a clear and consistent way. This report also looks at some of the barriers to adoption, with organizational silos being a major obstacle. Waters are further muddied by fragmented budgets, lack of clear governance and ownership and internal politics. The objective of our investment in this research project was to shed some light on these elements with a view to assisting organizations to create strategies that avoid or at least mitigate some of these barriers to success. Management of change in such endea vours is a key part in enabling the appropriate alignment of business and technology to support their transformation efforts. I hope that you find this report of benefit in the further adoption of Business Process Management. Get the full report here.

• Creating a Corporate Data Hub

  - by BuckWoody

  The Windows Azure Marketplace has a rich assortment of data and software offerings for you to use – a type of Software as a Service (SaaS) for IT workers, not necessarily for end-users. Among those offerings is the “Data Hub” – a  codename for a project that ironically actually does what the codename says. In many of our organizations, we have multiple data quality issues. Finding data is one problem, but finding it just once is often a bigger problem. Lots of departments and even individuals have stored the same data more than once, and in some cases, made changes to one of the copies. It’s difficult to know which location or version of the data is authoritative. Then there’s the problem of accessing the data. It’s fairly straightforward to publish a database, share or other location internally to store the data. But then you have to figure out who owns it, how it is controlled, and pass out the various connection strings to those who want to use it. And then you need to figure out how to let folks access the internal data externally – bringing up all kinds of security issues. Finally, in many cases our user community wants us to combine data from the internally sources with external data, bringing up the security, strings, and exploration features up all over again. Enter the Data Hub. This is an online offering, where you assign an administrator and data stewards. You import the data into the service, and it’s available to you - and only you and your organization if you wish. The basic steps for this service are to set up the portal for your company, assign administrators and permissions, and then you assign data areas and import data into them. From there you make them discoverable, and then you have multiple options that you or your users can access that data. You’re then able, if you wish, to combine that data with other data in one location. So how does all that work? What about security? Is it really that easy? And can you really move the data definition off to the Subject Matter Experts (SME’s) that know the particular data stack better than the IT team does? Well, nothing good is easy – but using the Data Hub is actually pretty simple. I’ll give you a link in a moment where you can sign up and try this yourself. Once you sign up, you assign an administrator. From there you’ll create data areas, and then use a simple interface to bring the data in. All of this is done in a portal interface – nothing to install, configure, update or manage. After the data is entered in, and you’ve assigned meta-data to describe it, your users have multiple options to access it. They can simply use the portal – which actually has powerful visualizations you can use on any platform, even mobile phones or tablets.     Your users can also hit the data with Excel – which gives them ultimate flexibility for display, all while using an authoritative, single reference for the data. Since the service is online, they can do this wherever they are – given the proper authentication and permissions. You can also hit the service with simple API calls, like this one from C#: http://msdn.microsoft.com/en-us/library/hh921924  You can make HTTP calls instead of code, and the data can even be exposed as an OData Feed. As you can see, there are a lot of options. You can check out the offering here: http://www.microsoft.com/en-us/sqlazurelabs/labs/data-hub.aspx and you can read the documentation here: http://msdn.microsoft.com/en-us/library/hh921938

• Convert C# Silverlight App To AZURE CLOUD Platform?!?!

  - by Goober

  The Scenario I've been following Brad Abrams Silverlight tutorial on his blog.... I have tried following Brads "How to deploy your app to the Cloud" tutorial however i'm struggling with it, even though it is in the same context as the first tutorial.... The Question Is the application structure essentially the same as the original "non-cloud based version"!? If not, which parts are different? (I get that there is a Cloud Service project added to the solution) - but what else?! Connection String Issue In my "Non-Cloud based application", I make use of the ADO.Net Entity Framework to communicate with my database. The connection string in my web.config file looks like: <add name="InmZenEntities" connectionString="metadata=res://*/InmZenModel.csdl|res://*/InmZenModel.ssdl|res://*/InmZenModel.msl;provider=System.Data.SqlClient;provider connection string=&quot;Data Source=CHASEDIGITALWS3;Initial Catalog=InmarsatZenith;Integrated Security=True;MultipleActiveResultSets=True&quot;" providerName="System.Data.EntityClient" /></connectionStrings> However However the connection string that I get from SQL AZURE looks like: Server=tcp:k12ioy1rsi.ctp.database.windows.net;Database=master;User ID=simongilbert;Password=myPassword;Trusted_Connection=False; So how do I go about merging the two when I move the "non-cloud based application" to THE CLOUD?! Any help regarding converting a silverlight application to a cloud service and deploying it would be greatly appreciated

• Some free cloud solution to enhance your business

  - by Saif Bechan

  I am co-owner of a small internet business. I am in charge of IT, and I try to get things done as low cost as possible. When investing in servers, resources and overall business costs your project can soon turn into a financial disaster. Cloud solutions can help you in solving some financial problems, they can help you in scalability problems, and overall performance problems of your server or web application. Recently I moved the whole internal/external communication(email,calendar,documents) of my business to the cloud. I did this by using the free version of Google Apps. This works great and is a big advantage on multiple levels. I do not have to fight spam anymore on my system, and there are less resources used on my system. Also switching servers will go a lot easier. Questions Can you name some cloud solution that you have used, or some you just recommend. They can fairy form financial benefits, organizational benefits, performance benefits. It doesn't matter as soon as it helps you spread the load of your business.

• What considerations should be made for a web app to be released on a cloud hosted system?

  - by Rhubarb

  I have a web app that is primarily a WordPress app, but it pulls content from a Django app, simply by calling a service that uses Django models. My understanding of cloud computing is a bit vague. If the site needs to scale up with short notice, does the cloud provider (Amazon, Rackspace, whomever) simply spin up new instances (copies) of my initially configured server? How is state managed between all of them? Are there any good primers on this subject? It's hard to find much out there without getting caught up in the marketing.

• How to use LVM on Rackspace Cloud

  - by batrick

  Dear all, I am trying to set up a simple but effective solution to make a backup of my rackspace cloud servers. These servers each run subversion, trac, and some database-backed custom php applications. My idea is to set up a LVM and mount a volume under, say, /srv. In this volume, I keep the data from all applications. Instead of caring about how to back-up each app in a different way (svn hotcopy, trac-admin hotcopy, huge mess for mysql), I simply take an LVM snapshot and back this one up cloud files using the excellent cloudcity script (http://github.com/jspringman/cloudcity/blob/master/cloudcity). The advantage of this solution is that it is quick and easy, and LVM allows to make decent backups. As more apps are added, it should not be required to change the backup script much. The downside, and main point of my question here, is that I am not sure how to get LVM working on Rackspace cloud, because there is only one root volume and no service like Amazon's EBS. I was thinking it may be possible to create a large empty file and use this as a "physical volume". Has anybody done anything like this before? Or do you know why it can never work? It would be great to hear from you. Thanks, batrick

• SharePoint 2010, Cloud, and the Constitution

  - by Michael Van Cleave

  The other evening an article on the Red Tap Chronicles caught my eye. The article written by Bob Sullivan titled "The Constitutional Issues of Cloud Computing" was very interesting in regards to the direction most of the technical world is going. We all have been inundated about utilizing cloud computing for reasons of price, availability, or even scalability; but what Bob brings up is a whole separate view of why a business might not want to move toward the cloud for services or applications. The overall point to the article was pretty simple. It all boiled down to the summation that hosting "Things" in the cloud (Email, Documents, etc…) are interpreted differently under the law regarding constitutional search and seizure than say a document or item that is kept in physical form at a business or home. Where if you physically have it stored someone would have to get a warrant to search for it or seize it, but if it is stored off in the cloud and the ISV or provider is subpoenaed for the item then they will usually give access to the information. Obviously this is a big difference in interpretation of the law and the constitution due to technology. So you might ask "Where does this fit in with SharePoint? Well the overall push for this next version of SharePoint is one that gives a business ultimate flexibility to utilize the Cloud. In one example this upcoming version gracefully lends itself to Multi Tenancy so that online or "Cloud" hosting would be possible by Service Providers. Another aspect to the upcoming version is that it has updated its ability to store content outside of the database and in a cheaper commoditized storage facility. This is called Remote Blob Storage (or RBS) which is the next evolution of External Blob Storage (or EBS). With this new functionality that business might look forward to it is extremely important for them to understand that they might be opening themselves up to laws that do not need a warrant to search or seize their information that is stored in the cloud. It will be interesting to see how this all plays out in the next few months. Usually the laws change slowly in comparison to technology so it might be a while until we see if it is actually constitutional to treat someone's content on the cloud differently as it would be in their possession, however until there is some type of parity that happens or more concrete laws regarding the differences be very careful about what you put in the cloud.

• Cloud security and privacy

  - by Rakesh K

  Hi, I have a very basic doubt regarding cloud computing that is catching up pretty fast these days. To my understanding, cloud computing is a paradigm in which companies put up their data and applications on somebody else's machines aka 'The Cloud'. I want to know just how secure is it to put up my data on some third party machines, especially if my data contains private details. In particular, how can an enterprise trust the cloud computing service providers in this data privacy aspect? Thanks, rakesh.

• New cloud development workflow using Github, Cloud9ide and CloudFoundry.

  - by weng

  So time is changing towards cloud development/computing. I'm trying to get the new "cloud" workflow based on the services I'm going to use: Github, Cloud9ide and CloudFoundry. Here is what is on my mind: Github acts like a central (main repo) just like yesterday's local filesystem. Every service will base it service upon this main repo. Workflow: Github: I create a new Github repo served as main repo for the project. Cloud9ide. I open my Github repo and write my tests and implementation (BDD/TDD). When I'm ready I save (commit) it to main repo on Github. X: A running instance of Jenkins detects someone has committed and fetches the latest commit, builds, deploys, tests (yeti and/or selenium) and reports if the tests were passed or not. If not, I make another commit til all tests are passing. X: I run the CloudFoundry commands to push the main Github repo to CloudFoundry's server and it will deploy my app automatically. What I'm still confused about is where this X environment will be. On a local server where I have to install Jenkins? Or could I install it on Cloud9ide (when java is supported) or will it be on another cloud service? Also, that X environment has to be able to fetch (clone) the Github repo and run the build scripts. And since the concept of Cloud9ide is very new and there haven't been any other predecessors I really wonder how the workflow will look like. We all know Github's workflow. We now know CloudFoundry's workflow (deploy/scale with a restful API/command line tool). But how Cloud9Ide will operate is still somewhat unclear to me. Someone on Cloud9ide mentioned that there will be buttons like deploy so I can deploy with one click. But that I guess will depend on what services that deploy process will hook up into etc. Could someone enlighten this cloud workflow topic and fill in the gaps. Thanks.

• HDFC Bank's Journey to Oracle Private Database Cloud

  - by Nilesh Agrawal

  One of the key takeaways from a recent post by Sushil Kumar is the importance of business initiative that drives the transformational journey from legacy IT to enterprise private cloud. The journey that leads to a agile, self-service and efficient infrastructure with reduced complexity and enables IT to deliver services more closely aligned with business requirements. Nilanjay Bhattacharjee, AVP, IT of HDFC Bank presented a real-world case study based on one such initiative in his Oracle OpenWorld session titled "HDFC BANK Journey into Oracle Database Cloud with EM 12c DBaaS". The case study highlighted in this session is from HDFC Bank’s Lending Business Segment, which comprises roughly 50% of Bank’s top line. Bank’s Lending Business is always under pressure to launch “New Schemes” to compete and stay ahead in this segment and IT has to keep up with this challenging business requirement. Lending related applications are highly dynamic and go through constant changes and every single and minor change in each related application is required to be thoroughly UAT tested certified before they are certified for production rollout. This leads to a constant pressure in IT for rapid provisioning of UAT databases on an ongoing basis to enable faster time to market. Nilanjay joined Sushil Kumar, VP, Product Strategy, Oracle, during the Enterprise Manager general session at Oracle OpenWorld 2012. Let's watch what Nilanjay had to say about their recent Database cloud deployment. “Agility” in launching new business schemes became the key business driver for private database cloud adoption in the Bank. Nilanjay spent an hour discussing it during his session. Let's look at why Database-as-a-Service(DBaaS) model was need of the hour in this case  - Average 3 days to provision UAT Database for Loan Management Application Silo’ed UAT environment with Average 30% utilization Compliance requirement consume UAT testing resources DBA activities leads to $$ paid to SI for provisioning databases manually Overhead in managing configuration drift between production and test environments Rollout impact/delay on new business initiatives The private database cloud implementation progressed through 4 fundamental phases - Standardization, Consolidation, Automation, Optimization of UAT infrastructure. Project scoping was carried out and end users and stakeholders were engaged early on right from planning phase and including all phases of implementation. Standardization and Consolidation phase involved multiple iterations of planning to first standardize on infrastructure, db versions, patch levels, configuration, IT processes etc and with database level consolidation project onto Exadata platform. It was also decided to have existing AIX UAT DB landscape covered and EM 12c DBaaS solution being platform agnostic supported this model well. Automation and Optimization phase provided the necessary Agility, Self-Service and efficiency and this was made possible via EM 12c DBaaS. EM 12c DBaaS Self-Service/SSA Portal was setup with required zones, quotas, service templates, charge plan defined. There were 2 zones implemented - Exadata zone  primarily for UAT and benchmark testing for databases running on Exadata platform and second zone was for AIX setup to cover other databases those running on AIX. Metering and Chargeback/Showback capabilities provided business and IT the framework for cloud optimization and also visibility into cloud usage. More details on UAT cloud implementation, related building blocks and EM 12c DBaaS solution are covered in Nilanjay's OpenWorld session here. Some of the key Benefits achieved from UAT cloud initiative are - New business initiatives can be easily launched due to rapid provisioning of UAT Databases [ ~3 hours ] Drastically cut down $$ on SI for DBA Activities due to Self-Service Effective usage of infrastructure leading to  better ROI Empowering  consumers to provision database using Self-Service Control on project schedule with DB end date aligned to project plan submitted during provisioning Databases provisioned through Self-Service are monitored in EM and auto configured for Alerts and KPI Regulatory requirement of database does not impact existing project in queue This table below shows typical list of activities and tasks involved when a end user requests for a UAT database. EM 12c DBaaS solution helped reduce UAT database provisioning time from roughly 3 days down to 3 hours and this timing also includes provisioning time for database with production scale data (ranging from 250 G to 2 TB of data) - And it's not just about time to provision,  this initiative has enabled an agile, efficient and transparent UAT environment where end users are empowered with real control of cloud resources and IT's role is shifted as enabler of strategic services instead of being administrator of all user requests. The strong collaboration between IT and business community right from planning to implementation to go-live has played the key role in achieving this common goal of enterprise private cloud. Finally, real cloud is here and this cloud is accompanied with rain (business benefits) as well !

error state. ubuntu@node7:~$ nova --debug boot --flavor 1 --image 28bed1bc-bc1c-4533-beee-8e0428ad40dd --key_name key2 --security_group default cirros REQ: curl -i http://keyStone.IP:5000/v2.0/tokens

• Handling HumanTask attachments in Oracle BPM 11g PS4FP+ (I)

  - by ccasares

  Adding attachments to a HumanTask is a feature that exists in Oracle HWF (Human Workflow) since 10g. However, in 11g there have been many improvements on this feature and this entry will try to summarize them. Oracle BPM 11g 11.1.1.5.1 (aka PS4 Feature Pack or PS4FP) introduced two great features: Ability to link attachments at a Task scope or at a Process scope: "Task" attachments are only visible within the scope (lifetime) of a task. This means that, initially, any member of the assignment pattern of the Human Task will be able to handle (add, review or remove) attachments. However, once the task is completed, subsequent human tasks will not have access to them. This does not mean those attachments got lost. Once the human task is completed, attachments can be retrieved in order to, i.e., check them in to a Content Server or to inject them to a new and different human task. Aside note: a "re-initiated" human task will inherit comments and attachments, along with history and -optionally- payload. See here for more info. "Process" attachments are visible within the scope of the process. This means that subsequent human tasks in the same process instance will have access to them. Ability to use Oracle WebCenter Content (previously known as "Oracle UCM") as the backend for the attachments instead of using HWF database backend. This feature adds all content server document lifecycle capabilities to HWF attachments (versioning, RBAC, metadata management, etc). As of today, only Oracle WCC is supported. However, Oracle BPM Suite does include a license of Oracle WCC for the solely usage of document management within BPM scope. Here are some code samples that leverage the above features. Retrieving uploaded attachments -Non UCM- Non UCM attachments (default ones or those that have existed from 10g, and are stored "as-is" in HWK database backend) can be retrieved after the completion of the Human Task. Firstly, we need to know whether any attachment has been effectively uploaded to the human task. There are two ways to find it out: Through an XPath function: Checking the execData/attachment[] structure. For example: Once we are sure one ore more attachments were uploaded to the Human Task, we want to get them. In this example, by "get" I mean to get the attachment name and the payload of the file. Aside note: Oracle HWF lets you to upload two kind of [non-UCM] attachments: a desktop document and a Web URL. This example focuses just on the desktop document one. In order to "retrieve" an uploaded Web URL, you can get it directly from the execData/attachment[] structure. Attachment content (payload) is retrieved through the getTaskAttachmentContents() XPath function: This example shows how to retrieve as many attachments as those had been uploaded to the Human Task and write them to the server using the File Adapter service. The sample process excerpt is as follows:  A dummy UserTask using "HumanTask1" Human Task followed by a Embedded Subprocess that will retrieve the attachments (we're assuming at least one attachment is uploaded): and once retrieved, we will write each of them back to a file in the server using a File Adapter service: In detail: We've defined an XSD structure that will hold the attachments (both name and payload): Then, we can create a BusinessObject based on such element (attachmentCollection) and create a variable (named attachmentBPM) of such BusinessObject type. We will also need to keep a copy of the HumanTask output's execData structure. Therefore we need to create a variable of type TaskExecutionData... ...and copy the HumanTask output execData to it: Now we get into the embedded subprocess that will retrieve the attachments' payload. First, and using an XSLT transformation, we feed the attachmentBPM variable with the name of each attachment and setting an empty value to the payload: Please note that we're using the XSLT for-each node to create as many target structures as necessary. Also note that we're setting an Empty text to the payload variable. The reason for this is to make sure the <payload></payload> tag gets created. This is needed when we map the payload to the XML variable later. Aside note: We are assuming that we're retrieving non-UCM attachments. However in real life you might want to check the type of attachment you're handling. The execData/attachment[]/storageType contains the values "UCM" for UCM type attachments, "TASK" for non-UCM ones or "URL" for Web URL ones. Those values are part of the "Ext.Com.Oracle.Xmlns.Bpel.Workflow.Task.StorageTypeEnum" enumeration. Once we have fed the attachmentsBPM structure and so it now contains the name of each of the attachments, it is time to iterate through it and get the payload. Therefore we will use a new embedded subprocess of type MultiInstance, that will iterate over the attachmentsBPM/attachment[] element: In every iteration we will use a Script activity to map the corresponding payload element with the result of the XPath function getTaskAttachmentContents(). Please, note how the target array element is indexed with the loopCounter predefined variable, so that we make sure we're feeding the right element during the array iteration:  The XPath function used looks as follows: hwf:getTaskAttachmentContents(bpmn:getDataObject('UserTask1LocalExecData')/ns1:systemAttributes/ns1:taskId, bpmn:getDataObject('attachmentsBPM')/ns:attachment[bpmn:getActivityInstanceAttribute('SUBPROCESS3067107484296', 'loopCounter')]/ns:fileName)  where the input parameters are: taskId of the just completed Human Task attachment name we're retrieving the payload from array index (loopCounter predefined variable)  Aside note: The reason whereby we're iterating the execData/attachment[] structure through embedded subprocess and not, i.e., using XSLT and for-each nodes, is mostly because the getTaskAttachmentContents() XPath function is currently not available in XSLT mappings. So all this example might be considered as a workaround until this gets fixed/enhanced in future releases. Once this embedded subprocess ends, we will have all attachments (name + payload) in the attachmentsBPM variable, which is the main goal of this sample. But in order to test everything runs fine, we finish the sample writing each attachment to a file. To that end we include a final embedded subprocess to concurrently iterate through each attachmentsBPM/attachment[] element: On each iteration we will use a Service activity that invokes a File Adapter write service. In here we have two important parameters to set. First, the payload itself. The file adapter awaits binary data in base64 format (string). We have to map it using XPath (Simple mapping doesn't recognize a String as a base64-binary valid target):  Second, we must set the target filename using the Service Properties dialog box:  Again, note how we're making use of the loopCounter index variable to get the right element within the embedded subprocess iteration. Handling UCM attachments will be part of a different and upcoming blog entry. Once I finish will all posts on this matter, I will upload the whole sample project to java.net.

• BPM ADF Task forms. Checking whether the current user is in a BPM Swimlane

  - by Christopher Karl Chan

  So this blog will focus on BPM Swimlane roles and users from a ADF context.So we have an ADF Task Details Form and we are in the process of making it richer and dynamic in functionality. A common requirement could be to dynamically show different areas based on the user logged into the workspace. Perhaps even we want to know even what swim-lane role the user belongs to.It is is a little bit harder to achieve then one thinks unless you know the trick. [Read More]

• In times where there are lot of cloud based hostings what would still make you go for dedicated or vps hosting ?

  - by Samyak Bhuta

  Are dedicated hosting yet cheaper and would remain so ? Do they really going to survive as cloud based offering are also getting cheaper day by day ? I am asking to gain perspective of long term scenario in hosting space as well as to know what is the current situation. Everywhere I go there is this buzzword "cloud" and audience don't even bother to compare it with dedicated hosting options. Is cloud really the way to go ahead ? what are it's cons ?

• Azure cloud app subdomain pointing to actual domain

  - by Amit Aggarwal

  Say we have a domain xyz.com registered with some registrar ... we pointed that domain to the name server of our dedicated server where the DNS will be hosted for that domain. Now, we just want that dedicated server to host the emails coming and the domain will point to abc.cloudapp.net (azure cloud app, they don't provide any static IP ... and only public url is given) Now, someone please helping me in editing/creating the DNS file on our dedicated server to make sure things work properly... if possible past here minimum settings we need in DNS file to make sure mails are on dedicated server and app is on cloud... Thanks, Amit

• Web Site Serving, Cloud-Computing, oh, my

  - by Frank

  I'm planning a software based service. To give it a bit of context (type of traffic), assume it similar to facebook in nature (with a little GitHub thrown in). I've been trying to understand my different hosting options. I've been using a shared host with GoDaddy for years just fine. I currently host a Wordpress web site there and I've not had any problems. Quite frankly, they've taken good care of me. However, the nature of a shared hosting environment is limited in nature. For example, I can't do anything but host a web site there. For example, I can not run a Mercurial server. Last time I attempted to build a web application with the intention of eventually launching it via GoDaddy, I ran in to all sorts of troubles because it was shared-hosted. Assembly issues, etc. At the time, the cost and time sank my project. (The lack of direct access was also frustrating.) (to be fair to godaddy, this was over 3 years ago) I've been looking at Rackspace or Amazon as a possible cloud solution but it seems to be just processing power and bandwidth (and an OS). From what I understand, I'd need to get Apache and MySQL Working on my own. The way cloud hosting is priced, however, seems appealing. I figure my final option might be to use a virtual private host. I think this would be more flexible than a shared-host site but less scalable than a cloud based server. So, I guess my question is what is an appropriate solution for someone who intends to build a web application service? I figure that I need to establish a hosting environment now rather than later so I can plan to effectively use the environment. I'd prefer to be fairly economical to start out with. I really can't afford to pay $999 (or even $99) while I build up the site and get the core functionality online but at the same time, I'd like to have the selected environment grow as needed. Thank you.
