本文介绍了757机内存出错后的处理。对于瞬态性一位错,纠错后继续执行,瞬态性多位错或地址错,转道工作。永久性一位错,纠错后继续执行,或倒换内存体后继续执行,并进行故障定位供检修用。永久性多位错或地址错,进行故障定位,并如为读错则侧换体后转道工作,否则不倒换体即转道工作。若备份体已用完,读错也不倒换体。当所有用户程序都有永久性多位读错时,则进行系统初启,根据可用体的情况进行切体及重组合,然后启动机器工作。
This article describes the 757 machine memory error handling. For the transient one bit error, continue to perform after error correction, transient multi-bit error or address wrong, go to work. A permanent one error, error correction continue to implement, or switch the memory body to continue the implementation, and troubleshooting for maintenance purposes. Permanent multi-bit wrong or wrong address, fault location, and if the wrong side of the body after the swap for the work, or do not switch the body that is, work. If the backup body has run out, read the wrong nor change body. When all user programs have a permanent multi-bit read error, then the system Kai, according to the availability of the body cut and reassemble, and then start the machine work.
