TPCS Construction Impact on ACT Computer Center

The ACT Computer Center is located in TPCS (Torrey Pines Center - South)
where long awaited building repairs are underway. The repair work at TPCS
requires the contractor to remove all exterior floor tiles. These tiles
are cemented in place and a jackhammer must be used to remove them. The
vibrations throughout the building caused by the jackhammer create enough
movement on the heads of disk equipment in the ACT Data Computer Center so
as to make them unreliable. In one incident the head actually came in
contact with the disk surface requiring the replacement of the entire
assembly. The only way to prevent this from reoccurring is to power down
the disk equipment while the jackhammer is in use.

Therefore, during the next four to eight week period, it will be necessary
to shut down the computer system each weekday evening. IFIS will be
shutdown from 4:00 p.m. until midnight. ISIS, PPS and DSE will be
shutdown from 5:00 p.m. until midnight. This shutdown will have
significant impact on the ability of ACT to complete the nightly batch
production and DSE extract activity. In order to complete the biweekly
and monthly payroll processing, the production Payroll Personnel System
may be required to be off-line the following day. Details have been
worked out so that Priority Student Registration will be able to proceed
as scheduled. The new online weekday hours will be from midnight until
4:00 p.m. for IFIS and from midnight until 5:00 p.m. for ISIS, PPS and
DSE.

ACT will attempt to keep our customers advised as to the impact of this
construction on operations. If you have any questions or problems, please
do not hesitate to contact the HELP DESK at extension 41853. ACT asks for
your cooperation and assistance during this period in curtailing scheduled
activities as much as possible. ACT will do everything possible to
minimize the disruption to the operations of the center. ACT thanks you
for your understanding and patience during this period.
