SUBJECT: 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.
