26 ZSCP-EVT-BKP-NEWPROCESS-ERR
created, and the backup process is not created. The procedure can fail due to a shortage
of time-list elements (TLEs). TLEs are system resources configured during system
generation. The system allocates one TLE for each call to a timeout procedure. If all
configured TLEs are allocated, a procedure call requiring a TLE fails.
Effect. There is no 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 gives up attempting to create a backup process. If
there is no backup process, the SCP process is not executing in fault-tolerant mode.
Recovery. Do not let the SCP process try indefinitely to create a backup process, but it
should have a backup. 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.
26 ZSCP-EVT-BKP-NEWPROCESS-ERR
An SCP process call to the Guardian NEWPROCESS or PROCESS_CREATE_
procedure failed.
ZSCP-TKN-ERRCODE
contains the error code returned by NEWPROCESS.
ZSCP-TKN-ACTION
indicates SCP’s response to the error:
Cause. An SCP process call to the NEWPROCESS procedure failed when trying to
start a backup process.
Effect. The SCP process issues this event and, depending on the error, either continues
to try creating a backup or gives up, as indicated by ZSCP-TKN-ACTION.
If the error is caused by 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 gives up trying to create a backup process. If there is no
backup process, the SCP process is not executing in fault-tolerant mode.
