ISTC's main purpose is to provide information services through computer facilities and library services. Besides providing regular services, IPC staff provided the following supports during FY 2001.
- Replacement of workstations in Computer Exercise Room 1 through 2, CAI Room1 through 2, faculty's offices, replacement of workstations for graduate students use, and replacement of related servers such as faculty file servers (procsvXX), printer servers(proxsvXX), etc.
- Replacement of MUSE system with a new library system and a new administration system.
- Starting Web server registration system in order to increase the degree of security.
- Discussion on how to reconstruct AINS network systems in order to provide more stable communication services.
Concerning Library services, 246 volumes Japanese Books, 529 volumes Foreign Books, 128 Japanese Magazines, and 465 foreign Magazines were purchased with
2001 regular budget.

To provide rich IT learning opportunity, about 500 workstations distributed in classrooms are operated 24 hours a day, and uniform environment for file and network is provided in our university. Each host is running continuously, sometimes unnecessary processes are remain and would cause troubles. Logging for all processes is done periodically, for sustaining good situation, it is hard to extract problematic processes from such huge logs. In this paper, on managing distributed hosts, a tool which support administrator by automating such information extraction steps is described. From the information of processes on each host, using simple descriptions of troubles obtained from a profiling method, trouble signs expected from experiences can be extracted. Search expressions in external modules are dynamically linked into the tool. By this structure, we could develop a good tool with expandabilityand easiness for system administrators. |

The required performance for WWW servers is growing day by day. Many high performance WWW server techniques including the distributed Web Servers are investigated. For good solution, portability, robustness against request bursts, and ease in implementation are needed. We propose aWWW Request Distribution method based on the URL rewriting feature, which is provided by a built-in module of the Apache Server { without modification of source files { with full portability. Combined with DNS based request distribution, it can also overcome the load imbalance cases on simple DNS based distribution. In this research, a combination method is proposed. Evaluations show that this method can provide more flexible load distribution with low implementation overhead. |
