Abstract: A new file system is mounted to a mount point of an existing file system implemented in a computational system. A sentinel indicator is stored in the mount point. Prior to initiating an input/output (I/O) operation by a program, a determination is made by the program as to whether the sentinel indicator exists. In response to determining by the program that the sentinel indicator exists, the I/O operation is performed by the program. In certain alternative embodiments, in response to determining by the program that the sentinel indicator exists, the I/O operation is not performed by the program.

Abstract: Provided is a method, system, and program for handling errors in a service program including service functions capable of being called from application programs. A call is received for one service function from a service function call within one application program. A series of test operations are performed when executing the service function call. Each test operation returns an identifier if the test operation failed where each identifier is associated with one error state. If one test operation failed, then the identifier for the failed test operation is transferred to an error handling agent, wherein the error handling agent accesses error information associated with the identifier and generates error information describing a specific cause of the error that caused the test operation to fail and then returns to the application program with a generic return code.

Abstract: Disclosed is a system for notifying a user of account activity, such as a withdrawal from a savings or checking account. A computer system maintains information on financial accounts and electronic user contact information for at least one of the financial accounts, such as a telephone number, e-mail address or pager number. Information on a transaction with respect to one of the financial accounts is received and processed. The computer system then processes the information on the transaction and generates an electronic message providing information on the transaction. The user contact information for the financial account involved in the transaction is processed. The message is then electronically transmitted to the location identified by the user contact information for the financial account.

Abstract: A system and method are provided for dispersing storage of a plurality of related and unrelated data items on a plurality of removable recordable media instances (RMIs). A first storage device is provided for storing a data item on a qualifying related RMI, the qualifying related RMI having one or more related data items stored on it and having sufficient actual storage space remaining for storing the data. A multiplier device is connected to the first storage device for multiplying the actual size of a data item, which is not stored by the first storage device because there is no qualifying related RMI, by a factor greater than one, to produce reserved storage space data which characterizes any other RMI that actually stores the data item.
