Embodiments of the present invention provide a method, system and computer program product for automated cluster member management based on node capabilities. In one embodiment of the invention, a method for automated cluster member management based on node capabilities can be provided. The method can include defining a membership policy for a cluster, the membership policy specifying a nodal configuration required for a node in a cluster. The method further can include evaluating different nodes in a computing environment against the membership policy for the cluster. Finally, the method can include associating cluster members in the cluster to only those of the nodes having respective configurations meeting the nodal configuration of the membership policy. Likewise, the method can include evaluating nodes already in the cluster, and disassociating cluster members in the cluster from those of the nodes having respective configurations failing to meet the nodal configuration of the membership policy.

Automated cluster member management based on node capabilities

Techniques for improving application server performance and availability are provided. In one aspect, a method of monitoring the health of one or more application servers comprises the following steps. One or more health classes are specified, each of the one or more health classes defining one or more health policies for the one or more application servers. At least one of the one or more health policies is monitored. Violations, if any, of the one or more health policies are detected.

Techniques for health monitoring and control of application servers

An implementation is described for navigating media. The implementation includes displaying a portion of the media. The implementation also includes displaying a navigation interface corresponding to the media. The navigation interface includes an active region, a current view region, and a ghost region. The active region corresponds to at least a portion of the media. The current view region corresponds to a portion of the media to be displayed. The current view is at least partially defined by a selector handle. The ghost region is coupled to the active region. The ghost region represents a range of remaining media other than the portion of the media in the active region. The ghost area provides a context for the remaining media relative to the portion of the media corresponding to the active region. The implementation also includes receiving user input to navigate the media according to a visual interaction between the sector handle and the ghost region.

Navigation interface with ghost region

A computer automated method for bubbling-up condition severity indicators in a hierarchical tree control can include identifying a node in the hierarchical tree control that has been obscured in a collapsed branch of the hierarchical tree control, bubbling-up a status for the identified node to a visible parent node, rendering a status icon for the status adjacent to the visible parent node, and, responsive to an expansion of the collapsed branch rendering the identified node visible, relocating the status icon adjacent to the identified node. Optionally, a depth can be determined for the identified node, a visual characteristic for the status icon can be selected based upon the depth, and the status icon can be rendered using the selected visual characteristic.

Bubbling up task severity indicators within a hierarchical tree control

The Rule Editing Program (REP) displays a rule in a hierarchical tree topology, wherein individual rule portions can be reordered by moving them to different locations within the rule using drag and drop interaction. Dragging and dropping rule portions results in the rule itself being changed accordingly. Additionally, new rule portions can be added to any part of the rule, including the beginning, middle and end. Finally, the entire rule, and individual rule portions, can be expanded all the way out, and collapsed all the way in.

Drag and drop rule topology

A method, system and apparatus for on-demand application resource allocation. In accordance with the method of the invention, an anticipated workload can be compared to a measured capacity for an application cluster in one or more server computing nodes in a server farm. If the measured capacity warrants a re-configuration of the application clusters, a new placement can be computed for application server instances in individual ones of the server computing nodes. Subsequently, the new placement can be applied to the server computing nodes in the server farm. In this regard, the applying step can include starting and stopping selected ones of the application server instances in different ones of the server computing nodes to effectuate the new placement.

Methods, systems, and media to test a code segment of a source file are disclosed. Various embodiments machine-render a source code skeleton in response to a selection of the code segment, incorporate the code segment into the source code skeleton to generate a temporary source file, insert a monitoring statement into the temporary source file, and compile the temporary source file into a compiled program to output a result. Embodiments may further include executing the compiled program and outputting the result. In addition, some embodiments also initiate compilation of the temporary source file, attempt to resolve a compilation error, and output the compilation error. Some embodiments terminate execution in response to selection of a cancel button. Further, some embodiments delete the temporary source file. Several embodiments also include a file creator, a code gatherer, a code generator, an adaptive compiler, a processor, and an output device.

Evaluation of a code segment

An infrastructure for handling the administration of possible and mandatory input arguments at runtime for software program code. A user alterable argument descriptor file (ADF) stores all information related to input and output arguments for a software program and its constituent subpieces. During invocation of a software program, all command line flags and values are validated against the ADF, and valid pairs are stored in a key/value dictionary which is passed to the software program. Each subpiece of the software program may then access its needed arguments from the dictionary independently of other subpieces, thereby allowing modifications to subpieces which require new or changed arguments without the need to recompile the entire software program.
