(1) The component of a Content Manager system that manages objects. These objects are referred to by items stored on the library server.<br />(2) An application, program, or transaction that manages and controls access to shared resources such as memory buffers and data sets. WebSphere MQ, CICS, and IMS are resource managers.<br />(3) See managed resource.<br />(4) A subsystem or component that manages resources that can be involved in transactions. Resource managers can be categorised as work managers, data resource managers, and communication resource managers.<br />(5) The participant in a transaction responsible for controlling access to recoverable resources. In terms of the CICS resource adapters this is presented by an instance of a ConnectionFactory.<br />(6) In the Tivoli common agent services , the server of a management application that directly interacts with a managed resource. For example, a resource manager instals bundles on the agent and starts and stops a subagent. See also management application.<br />(7) In an XA-enabled environment, software that manages and provides access to shared resources, such as databases. The DB2 database system is an example of a resource manager.<br />(8) A function that is responsible for managing a particular resource and that guarantees the consistency of all updates made to recoverable resources within a logical unit of work. The resource that is being managed can be physical (for example, disc or main storage) or logical (for example, a particular type of system service).<br />(9) A participant, in the execution of a two-phase commit, that has recoverable resources that could have been modified. The resource manager has access to a recovery log so that it can commit or roll back the effects of the logical unit of work to the recoverable resources.

(1) The concept of separating the definitions of logical and physical data such that application programmes do not depend on where or how physical units of data are stored; the reduction of application programme modification in data storage structure and access strategy.<br />(2) In CICS, the ability to request data by a high-level data-management method without concern as to how the data is stored or retrieved.
Industry:Software
(1) The condition allowing users to access and use their applications and data.<br />(2) The time periods during which a resource is accessible. For example, a contractor might have an availability of 9 AM to 5 PM every weekday, and 9 AM to 3 PM on Saturdays.<br />(3) The delivery of reliable service during scheduled periods<br />(4) The total amount of time that a resource can devote to new assignments.
