The present invention provides a method, system, and computer program product for routing sessions to a specific Uniform Resource Locator (URL) in a multi-site environment. An ordered list of servers is provided in a multi-site environment. Upon receipt of a session request submitted by a user, the ordered list of servers is looped through until a valid URL is found. When a valid URL is found, the session request is redirected to the server in the multi-site environment specified by the valid URL.

System and method for logging significant events occurring at a web site portal includes a base class portlet service including a significant event catcher method having a register method and a record method, a portlet action table, and an action description table. The register method is called during portlet initialization to register one or more significant event descriptions to the action description table. The portlet, upon executing a significant event, calls the record method to record the event to the portlet action table.

An arrangement for incorporating a magnetic bubble memory (MBM) into a system having a system processor and a direct access storage (RAM) utilizes digital command words that represent basic MBM data operations. The processor controls the MBM indirectly by assembling strings of command words in RAM which are transferred to a control interface individually by a direct memory access device. The interface then translates the command words into a set of control signals that are applied to the drive system of the MBM. Each string of command words preferably corresponds to a complete memory read or write operation or a major portion thereof.
