Various embodiments are provided for saving a log data in a hierarchical storage management system using a disk system as a primary cache with a tape library as a secondary cache. The user data is stored in the primary cache and written into the secondary cache at a subsequent period of time. Blank tapes in the secondary cache are prepared for storing the user data and the log data, based on priorities. At least one of the blank tapes is selected for copying the log data and the user data from the primary cache to the secondary cache based on priorities.

The selection of at least one of the blank tapes completely filled with the log data is delayed for writing additional amounts of the user data.

Various embodiments are provided for saving a plurality of log data in a hierarchical storage management system using a disk system as a primary cache with a tape library as a secondary cache. The user data is stored in the primary cache and written into the secondary cache at a subsequent period of time. The plurality of blank tapes in the secondary cache is prepared for storing the user data and the plurality of log data based on priorities. At least one of the plurality of blank tapes is selected for copying the plurality of log data and the user data from the primary cache to the secondary cache based on priorities. The plurality of log data is stored in the primary cache. The selection of at least one of the plurality of blank tapes completely filled with the plurality of log data is delayed for writing additional amounts of the user data.

A window display enables a user to easily identify a window to which a selected object belongs. A computer system displays a plurality of windows, each of which includes one or a plurality of objects, and which displays a window to which a selected object belongs. The window field to which a selected object belongs is, in response to the selection of the object, displayed with an attribute, e.g., with a domain (background) color, that differs from that of other window fields. In this manner, it is possible for a user to easily identify the window of the selected object.

Method for displaying a window

The present invention provides a scheduler that is able to display two weeks of a last or a next month with the current month with legible fonts. When a zoom key is input by an operator, a monthly calendar is displayed with another week. If a particular date of the month is an early date of the month, one week of the last month is additionally displayed. If a particular date of the month is a late date of the month, one week of the next month is additionally displayed. When a centering key is input by an operator, five weeks are displayed so that a week with a particular date is displayed in the middle of the five weeks.
