Embodiments include methods, systems and computer program products for operating an electronic device having a touch screen display for displaying information. Embodiments include generating a designated location on the touch screen display for receiving a continuous touch contact. Based on detecting a continuous touch contact at the designated location, information is displayed on the touch screen. Based on detecting an absence of a continuous touch contact at the designated location on the touch screen display, the display of information is disabled.

Operating a device having a touch-screen display

A solution for performance optimization of a publish operation, for use with a system comprising a publisher to publish a message and to match a subscriber with the published message, embodiments of the solution comprising: in response to the publisher publishing a message, determining whether the matching subscriber is actively waiting for the published message; and in response to determining that the subscriber is not actively waiting, deferring delivery of the published message.

Performance optimization of a publish operation

A system and method for messaging in which, when a connection to a queue manager () is established, the queue manager allocates a Connection Identifier from the same name space () as Message Identifiers and returns this information () to the user. The user can then use this Connection Identifier as a Correlation Identifier, safe in the knowledge that it will not clash with any system generated Message Identifier or Correlation Identifier. A secondary benefit to this allocation scheme is that if a shared reply queue suffers from a build-up of messages then the Correlation Identifier in those messages can be used to identify the application expected to receive those messages.

System and method for messaging

Messages in a publish/subscribe system can be processed after they leave the original publisher and before they are delivered to an ultimate subscriber. Each published message has an associated topic string and a PubLevel value initially assigned by the original publisher. Subscribers are assigned different SubLevel values. These subscribers register their subscriptions with a broker. When a published message having the appropriate topic string is received, the broker performs a subscriber selection process using the message topic string, the current message PubLevel value and the assigned SubLevel values of subscribers registered for the topic string. When a subscriber is selected, the broker changes the message PubLevel value and transmits the message only to the selected subscriber. The subscriber may be an intercepting subscriber that processes the published message and then re-publishes it back to the broker. The broker may repeat the subscriber selection process multiple times with the published message being sent to multiple intercepting systems, each of which processes and republishes the message before the processed message is finally sent by the broker to an ultimate subscriber.
