10 ZSCP-EVT-BAD-BKP
Cause. An SCP call to the CHECKPOINT procedure failed. The SCP process tried to
checkpoint too much data (the stack size, the counts for all of the buffers, and the total
size of all of the file sync blocks).
Effect. The backup process does not receive the most recent checkpoint information.
The SCP process issues this message and calls the ABEND or PROCESS_STOP_
procedure. The backup SCP process receives system message –101, indicating process
abnormal deletion, and resumes processing from a previous checkpoint.
If there is no backup process, the file system returns error 201 (nonexistent process) to
every application that is awaiting a response from the SCP process. The process that
created the SCP process receives system message –101, indicating process abnormal
deletion.
Recovery. If there is no backup process, direct command messages to another SCP
process or hold them until another SCP process is started. If the problem recurs, obtain
this information (if available) before calling a Compaq representative: the
SAVEABEND file, the SCF log, the SCP trace file, and the CPU dump.
10 ZSCP-EVT-BAD-BKP
The backup SCP process has encountered an error.
Cause. The SCP backup process encountered an internal error.
Effect. The backup process stops immediately. The primary process is notified with
system message –101, indicating process abnormal deletion, and starts another backup
process.
If there is a process control block (PCB) problem, a memory allocation problem, a swap
file problem, or a communication problem with a CPU-monitor process, the SCP
process keeps trying to create a backup process. If there is any other problem, the SCP
process abandons its attempt to create a backup process.
Recovery. Obtain this information (if available) before calling a Compaq
representative: the SAVEABEND file, the SCF log, the SCP trace file, and the CPU
dump.
