A method, system and apparatus for dynamically reconfiguring partitions of a partitioned computer system are provided. Here, dynamically reconfiguring a partition is defined as being able to reconfigure the partition while the partition is operational. Using a graphical user interface (GUI), a user may indicate a plurality of resources that are to be involved in a partition reconfiguration. However, the partition is actually reconfigured one resource at a time. If one of the resources is memory, then memory is allocated to the partition or de-allocated from the partition one logical memory block (LMB) at a time. In reconfiguring partitions, resources may be removed, added or moved from one partition to another. Moving resources from one partition to another entails removing the resources from one partition and adding it to the other partition. After a partition re-configuration, a resource allocation table is updated. All this is done transparently to the user.

Procedure for dynamic reconfiguration of resources of logical partitions

The present invention provides a method, apparatus, and computer implemented instructions for managing a set of objects for a plurality of terminals. The set of objects are stored in a memory, such as a nonvolatile random access memory in a data processing system. The set of objects are used to configure logical partitions within the data processing system. Access to the set of objects is provided to the plurality of terminals through a service processor.

Method and apparatus for maintaining profiles for terminals in a configurable data processing system

A method and system for providing a computer system having a plurality of logical partitions with a virtual terminal is disclosed. The computer system is coupled to an external display device through a single communications interface. The method and system include allowing the logical partitions to share the communications interface by multiplexing communications to the display device for each of the logical partitions over the communication interface. Windows are displayed on the display device for each of the logical partitions, and the communications from each of the logical partitions is then routed to the corresponding window for display on the display device.

New adapter functions for a computer system are moved from existing TTY configuration code to load modules dynamically linked to the TTY configuration code at run time. A load module attribute stored in a vendor-supplied component of a database provides the load module path and name. Third party vendors may then add TTY configuration support by supplying the load module and adding the appropriate attribute(s) to the database, obviating system vendor assistance or source code access. Ease of configuration is enhanced by avoiding displays of TTY device characteristics not supported by currently installed system hardware. An additional type attribute for predefined attributes in the database permits TTY attributes specific to a particular adapter type to be stored under a unique identifier. The additional type attribute and query of a parent device of a TTY for extended attributes for other device types permit third party vendors to add new adapters by generating a load module linked at run time. Attributes specific to a given adapter are thereby easily added to the existing set of default attributes normally associated with a TTY.
