IBM Tivoli Storage manager (IBM TSM) is an enterprise classification backup and archiving software. IBM TSM, like every commercial enterprise backup utility items, is designed to make copies of a firm's data to give protection to against facts loss. akin to other business backup utility platforms, it permits policy-primarily based, automated records backup.
IBM Tivoli Storage manager can manage backup and archive statistics throughout disk arrays, tape libraries or optical storage and can automatically move facts because it a while to decrease performance storage. This method is occasionally referred to as tiered storage or hierarchical storage administration. policies can specify retention time, classification of storage media, frequency of backup, information classification and hardware to be backed up.
IBM TSM uses a modern incremental, or "incremental perpetually" backup scheme to compile backup records. The application takes an preliminary full backup and all subsequent backups are incremental -- this is, handiest adjustments to statistics are backed up. This conception at one time became pleasing to IBM TSM, however has develop into extra usual over time, specially amongst cloud backup providers.
Tivoli Storage supervisor is a real enterprise product, and as such, can be configured a variety of easy methods to meet a company's wants. it's most generally deployed at corporations with big amounts of backup facts and a workforce to manage it. IBM TSM is supported on quite a lot of hardware, including AIX, HP-UX, Linux, Solaris, and home windows Server. TSM's backup customer is purchasable for many supported types of essential working systems.

IBM will also offer its FastBack enterprise-classification backup service no longer for simply windows but for different working environments over time, based on a company product manager in an interview with BetaNews.
John Conner, an IBM product supervisor for both TSM and TSM FastBack, wasn't capable of specify which systems yet when speaking with us. "but we're taking a look at Linux, Solaris, and AIX, for example," noted Conner, who's product supervisor for each TSM and TSM FastBack.
IBM's TSM (Tivoli Storage supervisor) FastBack is its new storage back-up product based on technology obtained through its FilesX acquisition. The company launched FastBack simplest 90 days after its acquisition of FilesX in April all through a fresh storage business purchasing spree. Enabled with continuous records coverage (CDP) and file-level blocking, FastBack is designed to deliver managed again-up among both SMBs (small to medium-sized business) and disbursed businesses, Conner referred to.
He envisioned that in commercial enterprise settings, the product may be used right now largely for remotely administered implementations at branch places of work.
at the moment, TSM FastBack helps disk-enabled backup and "close-instant" recovery of home windows-primarily based file servers and purposes that encompass Microsoft alternate, Microsoft SQL Server, Oracle, and IBM's DB2 database, for instance.
FastBack replaces an earlier product from Tivoli, called TSM express, accompanied Lauren Whitehouse, a senior analyst on the business method neighborhood, in an extra interview.
"[But] TSM specific was a file-based mostly, batch-style backup greater reliant on tape media," the analyst informed BetaNews. "there's nothing definitely exciting about FastBack. There are other options love it available in the market. [Yet] IBM has a strong manufacturer, worldwide channel, and massive client base that it might leverage with FastBack."
Conner instructed BetaNews that IBM Tivoli views EMC and Symantec as among its desirable competitors in the storage market. He added that IBM plans deeper integration for FastBack -- in addition to for technology garnered through contemporary acquisitions of Diligent, Softek, and Arsenal Digital -- into IBM's TSM line-up.
"There may be other purposes of FastBack -- similar to in IBM BCRS's on-line backup solution, [based on the] acquisition of Arsenal Digital. Deduplication from Digilent can be utilized," Whitehouse cautioned, relating to a process by which multiple logical copies of information are represented via single actual copies. "Replication capabilities from Softek can be exciting," she brought.
TSM FastBack can be bought either on my own or as part of the TSM FastBack core, which also comprises two connected application products: Fastback for Microsoft change, and FastBack for bare computer healing.
IBM is increasing its footprint in the cloud these days with the debut of latest capabilities in virtualization, photograph administration and cloud computing, together with application that can virtualize a knowledge core within minutes.
IBM’s new advanced digital deployment application, which is now in open beta, enables IT establishments to create a cloud atmosphere with and deploy a single virtual computing device in seconds, dozens in a couple of minutes and tons of or hundreds. companies can install, configure and automate the advent of latest digital machines, making it simple to deploy machines on the fly.
IBM is additionally announcing new version of its Tivoli Provisioning manager, which automates data middle provisioning. the brand new utility permits users to right away installation pictures and optimize substances. And the Tivoli Storage supervisor for virtual Environments improves the frequency of backups to reduce the volume of information in danger, and permits quicker recuperation of information to cut back downtime following a failure.
IBM just posted robust revenue for q4 2010, with application revenues up 7 p.c from the identical quarter in 2009. most likely these new cloud applied sciences will help IBM continue to develop during this segment.

Using the Model-View-Controller (MVC) pattern, originally from Smalltalk, the majority of the Swing classes are implemented by using a variation of the MVC that collapses the view and controller into a single class called the delegate. (For more details on this topic, you can visit an online Swing tutorial, "What is Swing? - 2"). A working understanding of the model/delegate relationship will help you understand the classes and interfaces that accompany each of the Swing components.
As stated by Sun, "With the JTree class, you can display hierarchical data. JTree doesn't actually contain your data; it's simply a view of the data." The challenge comes from associating business objects with a corresponding Swing object. So how do you represent your current business objects in a JTree without altering your class definition of the business objects?
This article covers two alternatives. In both examples the objectives are to minimize (1) the coupling between the business objects and the JTree, and (2) the amount of effort and code to accomplish the tasks. In both examples I use a class called Vehicle that represents any business object and that can be displayed in hierarchical fashion.
Since the JTree is designed for displaying data with hierarchical properties, the only requirement is that there be methods within the business object's class definition to implement navigation within a hierarchical structure. In the examples, the Vehicle class has subtypes that provide a hierarchical structure. For example, one instance of the Vehicle class might be called "Motor Vehicle." The class could contain subtypes of Car, Truck and Van. These vehicles, while separate, share the commonality of being a motor vehicle.
Throughout this article I use terminology common to the JTree API and its associated classes and interfaces. The terminology is defined for you in the JTree Terminology table.
One aspect of the JTree that makes it more complex than other Swing classes is that the associated model in the model-delegate pattern for the JTree isn't where data is maintained. Take the JTextField class, for example. In JTextFields, the view (JTextArea) offers a setText(String) method, and its associated model (called a document) offers an insertString(int, String, AttributeSet). Both methods allow manipulation of the underlying data. In the case of the JTree, neither the JTree class nor its associated model interface - the javax.swing.tree.TreeModel - offers a means of manipulating the underlying data.
Another aspect of the JTree is the add(Component) method, which comes from being a subclass of the Container class. This method, however, is used for performing additions in the sense of containment (i.e., JPanels are commonly used to contain several other components by adding them to the JPanel), not for adding data to the JTree.
In the first example - AddData_ExampleA.java (see Listing 1) - associating a business object's data to the JTree is done using the default helper classes: javax.swing.tree.DefaultTreeModel and javax.swing.tree.DefaultMutableTreeNode. The default model class consists of the methods insertNodeInto(MutableTree-Node, MutableTreeNode, int) and removeNodeFromParent(MutableTree-Node).
These methods allow the addition and removal of nodes from the JTree. Since my business object, the Vehicle class, doesn't implement the MutableTreeNode interface, it can't be directly added to the JTree. Therefore, to make it a valid MutableTreeNode without altering the class definition, I "wrap" the Vehicle class using the DefaultMutableTreeNode.
JTree TerminologyNode: Any position within the JTree where data associated with the business object is being represented.Path: A collection of a contiguous set of nodes. A path can contain one or many nodes. A null path indicates a zero node path or an empty path. The collection of nodes will consist of a strict ancestry line. (If you think of a traditional organizational chart as a tree, then an example of a path would be the line drawn from you to the president or CEO.)Leaf: A special kind of node. As its name implies, this is the node at the end of a path. There are no more nodes connected to the leaf node. (Using the organizational chart example again, the leaf is the person that has no personnel reporting to him or her.)Root: A special kind of node. In comparison to a leaf, a root's parent information is never examined. It's the highest point within the hierarchy. A root's parent relationship either does not exist or doesn't need to be displayed.Parent: Represents a node's relationship with another node. In a parent/child relationship, the parent is analogous to a super class within the realms of object-oriented concepts.Child: Represents a node's relationship with another node. In a parent/child relationship, the child is analogous to a subclass of its parent. It inherits all the properties associated with its parent. (Note: As of JDK 1.2/Swing 1.1, a node can have only one parent.)
User Object: Refers to the business object associated with a node. While not required, all user objects will usually be of the same class type. (In the examples provided, the Vehicle class is used to represent the business object.)Editor: This is a component (usually an extension of a JComponent) that has the unique role of allowing the user to change the data of a specific node.Renderer: This is a component (usually an extension of a JComponent) that has the unique role of deciding how a node's data is to be displayed within the context of the JTree when a user isn't editing the data. (Note: Using an AWT component as an editor or renderer may generate unwanted results.)See http://java.sun.com/products/jfc/tsc/index.htmlTreeModelEvents: Swing provides the following three types of tree events:1. Expansion event - an event generated when a node is collapsed or expanded.2. Model events - there are four types of model events:a. node changed - generated after a node is changed. This is the only event the TreeModel interface supports with the method valueForPathChanged(TreePath path, Object newValue). While this method could be implemented to represent any of the four types of model events, typically this represents the node changed event, and the DefaultTreeModel class implements it as such.b. node inserted - generated when a node is inserted into the JTree.c. node removed - generated when a node is removed from the JTree.d. structure changed - a "catchall" event used when something drastic has happened to the structure of the JTree. It's the most expensive event as it may result in a repaint of the entire JTree.3. Selection event - an event generated when the selection of a node takes place.
Here are the steps performed within the code in AddData_ExampleA.java:1. Obtain a reference to a user object. An instance of the user object is created. In this example, the Vehicle class is the user object:Vehicle vObj = new Vehicle("Transportation Vehicles");
2. Create an instance of TreeNode. An instance of the DefaultMutableTreeNode class that implements the MutableTree-Node interface (a subinterface of Tree-Node) is created using the instance of the user object created in step 1. (The second argument indicates whether the node will allow children to be added to it. In this example, I want to allow children so I pass in the value true.)DefaultMutableTreeNode tRoot = new DefaultMutableTreeNode(vObj, true);
3. Create an instance of TreeModel. The DefaultTreeModel class implements the TreeModel interface and can be created using the TreeNode object that was created in step 2 as its constructor's argument:i_model = new DefaultTreeModel( tRoot );
4. Create an instance of the JTree. The JTree is created using the TreeModel object that was created in step 3:i_tree = new JTree( i_model );
5. Create a child TreeNode. When the user clicks the add button, another instance of the DefaultMutableTreeNode is created using another instance of the Vehicle class with the name of "Car":i_car = new Vehicle( "Car" ); i_carNode = new DefaultMutableTreeNode( i_car );
6. Add child node to the JTree. The method insertNodeInto(MutableTreeNode, MutableTreeNode, int) from the DefaultTreeModel class is invoked on the TreeModel that was created in step 3. There are three arguments. The first argument consists of using the instance of the DefaultMutableTreeNode that was created in step 5. The second argument calls for the parent of the object being inserted, which in this case is the root.
To obtain the root, the TreeModel interface provides a getRoot() method. (Note: the return type of getRoot() is Object, which requires casting the returned object to the MutableTreeNode class.) The third argument requires an int to indicate where within the children (assuming more than one child) the new node should be graphically positioned. Since there are no other children, the value used is 0:
i_model.insertNodeInto( i_carNode, (MutableTreeNode)i_model.getRoot(), 0 );
To see this example run, compile and execute the AddData_ExampleA.java (see Listing 1) source file. Upon executing the application, the JTree is displayed showing a single node - the root (see Figure 1).
To see this happen, click on the button labeled Remove Node: 'Car' button in the AddData_ExampleA.java program. By repeating steps 5 and 6, the program will construct the entire contents of a JTree.
While this add process is simple and easy to program, there are some shortcomings with this approach. First, it demands that the application constructing the JTree take full responsibility for constructing and maintaining all the hierarchical relationships between each node. The code to handle this can easily become too large and difficult to debug or maintain.
A second shortcoming is that the responsibility of keeping concurrent data accurate falls back on the application containing the JTree. Running the AddData_ExampleA class explains this. After you create and add the child node "Car," if the button labeled "Change Name to 'Van'" is clicked, the node that previously displayed "Car" will now display "Van." However, for the refresh to occur immediately, the following code is required:
i_model.valueForPathChanged( pathToRoot, i_car );
Another method, called valueForPathChanged(TreePath, Object), is provided as part of the TreeModel interface (see Figure 3). However, it again requires knowing which node has changed and the path in which it resides. The reason the update isn't "free" is because Swing is still not aware of attribute changes made to the node's user object.
A third shortcoming is with the use of the default classes that are provided by Swing. While convenient to use, it should be noted that certain limitations and costs exist. In my example, the DefaultMutableTreeNode is not a thread-safe class. Other issues relating to performance may need to be addressed when using the "default" classes in Swing.
It should also be noted that since the methods insertNodeInto() and removeNode() aren't part of the TreeModel interface, calls made to the getModel() method will require casting prior to invoking these methods. This defeats the advantage of using interfaces because if these methods were part of the TreeModel interface, then the cast to DefaultTreeModel after getModel() wouldn't be necessary.
The second example, displaying a business object's data in a JTree, is done by creating a tailored MutableTreeNode class. Writing my own MutableTreeNode class gives me a "bridge" between the user object class being displayed and the Swing MutableTreeNode interface. I use the term bridge to imply that there will be a translation between API calls invoked by one class and the appropriate methods invoked in a corresponding target class (see Figure 4).
This allows the target class (the user object class) to be free from knowing the functionality of the calling class, and vice versa. Therefore, the Vehicle class definition (see Listing 2) isn't influenced by how Swing is implemented.
Note: It's good practice to implement the toString() method in your objects to provide a meaningful String representation of the class. The JTree uses the toString() method to determine what text to display in the TreeNodes.
Accomplishing this requires completion of the two steps listed below:1. Create a MutableTreeNode (VehicleTreeNode) class (see Listing 3) for the Vehicle class. This class will implement the MutableTreeNode interface by invoking methods defined in the Vehicle class.2. Update the JTree to reflect changes made to the user object.
When changes are made to the underlying object the JTree won't update its view to reflect the new value until it's prompted to do so. As discussed earlier, the method valueForPathChanged(TreePath, Object) on the TreeModel will update the JTree view. However, to invoke the method requires a reference to the TreeModel that can't be obtained from a TreeNode. Therefore, I chose to implement an event mechanism as a logical means of communicating updates made by the MutableTree-Nodes to their associated user objects. This required creating two interfaces (UpdateEventSource, UpdateEventListener) (see Listings 4 and 5) and one class (UpdateEvent) (see Listing 6) for the event.
Now to bring it all together! Following is the sequence of steps that occurs when executing the AddData_ExampleB (see Listing 7) application class:1. Create an instance of the root Vehicle class:Vehicle wrkVehicle = new Vehicle( "Vehicle" );wrkVehicle.setType( "Motor" );wrkVehicle.setDescription( "Classification for motor vehicles" );
2. Create an instance of the VehicleTree-Node class. The argument used in its constructor is the Vehicle class that was created in step 1. The second argument is a Boolean that indicates if the node being created will allow children. In this example, the nodes will have children so the value of true is used:i_root = new VehicleTreeNode( wrkVehicle, true );
3. Create an instance of a TreeModel class. By using the DefaultTreeModel class, the constructor is passed in the root node created in step 1 and true is passed in to indicate that children are allowed:i_model = new DefaultTreeModel(i_root, true);
4. Create an instance of the JTree. The JTree is constructed using an instance of the DefaultTreeModel class, which is constructed using the VehicleTreeNode object that was created in step 3:i_tree = new JTree( i_model );
At this point the work is finished and the magic of the JTree begins (see Figure 5).
Here's how this works: subsequent calls are made by the JTree to the TreeNode (in my example, it's the VehicleTreeNode), asking if it allows children (allowsChildren). If so, it obtains a child count (getChildCount), iterates through the list of children and sets the current node as the parent (setParent) on the child node. This will repeat for each node until the leaf node is reached (getChildCount returns 0). Actually, the default behavior is to perform these steps in a lazy fashion. Rather than take a performance hit by obtaining the entire structure of the JTree right away, nodes are displayed in a collapsed state and wait until they're expanded before completing construction of the JTree.
Adding nodes to the JTree is accomplished by invoking methods similar to those in the first example. By invoking the DefaultTreeModel's method, insertNodeInto(MutableTreeNode, MutableTreeNode, int) with a VehicleTreeNode as the required MutableTreeNode, any subtypes associated with the Vehicle will also immediately appear on the JTree. This differs from the first example in that subsequent calls to the insertNodeInto() method would be required to add the subtypes of the Vehicle to the JTree. This can be seen by running the AddData_ExampleB.java application. The Truck/Vehicle is added to the root Vehicle prior to being added to the JTree. So when the root Vehicle is added to the JTree, the child node Truck is also added to the JTree without requiring the additional call to insertNodeInto().
It's worth noting that while the MutableTreeNode interface offers methods like insert(), remove() and removeFromParent(), invoking these methods directly to alter the parent /child relationships circumvents the TreeModel. Since the TreeModel maintains the view, changes made directly to the MutableTreeNodes won't be reflected until a forced repaint occurs (resizing the window, etc.).
SummaryThe first example demonstrated how data could be added to a JTree simply and easily. In the example, the handling of the details of the JTree was delegated to the Swing default classes. It's a good solution if the JTree is going to be used to display predominantly static or read-only data. However, if the JTree is to be used heavily, such as in an administration application, then the second alternative - creating a specific MutableTreeNode class to handle the translation between the graphical and data classes - may be more appropriate. It minimizes the resources necessary to perform the construction of the tree, as well as the code that needs to be written.
I hope this article assists developers who are new to Java, or to the JFC and Swing, to quickly become acclimated to the power of using a JTree to graphically represent and administer their data objects.
Anthony Franco's BlogOn March 20 at AJAXWorld 2008 East, Anthony Franco, UX & UI Expert, President of Effective User Interface will be keynoting on RIA Adoption in 2008 – Risks, Rewards, Challenges and Opportunities.
Last year, the overall demand for RIAs outpaced the qualified supply chain. This trend will continue in 2008. While last year brought unprecedented growth in RIA adoption— especially by Fortune 500 companies—RIA adoption in 2008 brings a new onslaught of risks, rewards, challenges, and opportunities for companies of all sizes.
This year, companies facing both job growth and decline will need to continue to leverage innovative, usable RIAs to hone their competitive edge to outpace their competition and improve core business practices with fast, reliable, productivity-enhancing internal and external tools. However, building and deploying effective RIAs is not something companies can jump into with blind assumptions.
Without the right leadership at the helm and the right team in the trenches, the world of RIAs is fraught with risk that can cost dearly. The flip side of the coin is that good RIAs can provide your customers with user experiences that leave your competition in the dust. If you keep the following risks and rewards front of mind, you can turn the 2008 RIA challenge into successful opportunities.
Risk #1: Developer inexperienceReward: RIAs that work result in user adoptionSince many underlying RIA technologies are still emerging, finding developers with the appropriate level of experience can be tough. Thinking that you can find good Java or .Net developers immediately turn them into expert Flex or Silverlight developers is not good thinking. Inherent to these powerful new frameworks are challenges that require mastery of the technologies. Rich client applications differ greatly from server, HTML, or desktop applications and require very certain development expertise. Beware the typical developer optimistic mindset that believes problem-solving skills are platform independent.
Risk #2 : Designer inexperienceReward: Well-designed RIAs make people want to use themThe gap between sexy and usable is huge and dangerous. A great print or web designer is not necessarily a great application designer, especially not right out of the gate. It takes a considerable shift of discipline and time on the front for designers to transition from page based metaphors to RIA necessities such as features, tasks, hierarchical navigation schemes, and transitional animations. Oddly, understanding how to leverage new technologies like AIR and Silverlight means that designers may have to unlearn some of what they have relied on in the past as successful solutions.
Forrester Research stat: 70 to 80 percent of all IT projects fail. The number one reason why they fail is a lack of user acceptance, not technical issues (caveat: user acceptance may be poor simply because an application just doesn’t work). An effective RIA designer who respects user input and usability measurement studies will dramatically mitigate the failure rate of an IT project. Look for RIA designers with experience and/or education in human factors.
Risk #3: Poor hiresReward: Powerful designer/developer collaborationManagers may see the words "Flex experience" on a resume and assume that, in-and-of-itself, Flex experience makes the candidate qualified. Differentiating between experience and quality is very hard for an IT manager to assess since they may have not yet seen what a good RIA developer really looks like. The same premise holds true for design talent. Hiring the wrong developer or designer obviously will likely point to costly disaster on any project.
Consider outsourcing to proven experts. Or build teams consisting of blended internal and external talent and give them prudent product management guidance.
Risk #4: Lack of process and cultureReward: Integrated workflow and new behaviorsLet’s say that you lucked out and put together a great team. Now you have to get them to collaborate. Establishing the right culture to enable the team to work together is critical to the success of creating engaging applications. It takes a delicate combination of humility, passion, confidence, knowledge, process, and realism to execute against business and user requirements.
Also, carefully consider reporting structures. Should the designer sit in Marketing? IT? Companies trying to build effective teams may be challenged by traditional organizational and hierarchical silos and boundaries to get the right people in the right room with the right priorities and agendas.
Risk #5: Messaging from platform providersReward: Great news across the boardBoth Adobe and Microsoft have emerging RIA platforms (AIR/Flex/Flash and Silverlight respectively). While the hype for Silverlight is hitting stride, currently the Adobe Flash/Flex/AIR platform is the way to go for most robust online applications. Microsoft’s roadmap is very exciting, and I believe that they will see some great moves forward on their platform in the next 12 months. However, the Silverlight runtime just does not offer enough functionality or the ubiquitous reach that the Flash Player does.
The opportunity, no matter the platform, is abundant. Microsoft entering the RIA game is great news for everyone, even Adobe. They have helped to validate that RIAs are the future of how companies will engage, inform, retain, and entertain, their customers.
Risk #6: RIA providers on overloadReward: Consistent home runsMany providers in the RIA space are growing more rapidly than they can realistically support— flirting with implosion and growth rates of 1,000 percent and higher. Without dedicated, qualified team members in place, RIA providers have no business taking on work just to take on work. If you come across an RIA provider who has people available immediately, beware. At EffectiveUI, they would rather turn away work than fatigue or dilute their human resources.
Risk #7: Inadequate budgetsReward: Proving the value of an RIAThe return on investing into a great RIA—even a simple one— can be astounding. Applying the same budget approach as you would, for example, a micro site or an HTML calculator is not the model to follow. Find guidance and build your case. Deploying an application that is truly going to engage users and deliver a measurable ROI requires appropriate budgeting of dollars and time.
Risk #8: Inappropriate intentionReward: Focused discipline for the jobHiring your advertising agency to build a critical business application is like asking your interior designer to engineer a new building. While both disciplines are important and somewhat related, they absolutely require pinpointed expertise and focus. Make sure that the person or company you engage to build your RIA understands and respects the difference.
