After generating appropriate diagnostic data, the system error routine examines the error options specified by the program that detected the error. These options indicate which recovery technique is needed. Recovery alternatives are:
When a catastrophic (unrecoverable) system error occurs, the present condition of the system is examined to determine the extent of the recovery procedures. The basic catastrophic recovery options are:
If additional program errors occur during catastrophic processing, the control program may decide that further processing is impossible. In this situation no attempt will be made to re-IPL the system; instead, a disabled wait PSW will be loaded. The 6-digit code in the address field of the PSW provides an indication of the nature of the error. These error codes are documented in TPF Operations.
