3 ZSCP-EVT-USESEGMENT-ERR
overloaded. For ALLOCATESEGMENT and SEGMENT_ALLOCATE_ error codes,
see Guardian Procedure Errors and Messages Manual.
3 ZSCP-EVT-USESEGMENT-ERR
An SCP call to the Guardian USESEGMENT procedure failed.
Cause. The SCP process called the USESEGMENT procedure to access a segment, but
the USESEGMENT procedure failed because the specified segment has not been
allocated.
Effect. The SCP process issues this message, stops the backup process if there is one,
and calls the ABEND or PROCESS_STOP_ procedure. 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.
4 ZSCP-EVT-BAD-CHKPT
An SCP call to the Guardian CHECKPOINT procedure failed.
Cause. An SCP call to the CHECKPOINT procedure failed. The CHECKPOINT
procedure checkpoints data into the CHECKMONITOR data area of the backup process.
Effect. The backup process does not have the information it needs to take over if the
primary process stops. The SCP process stops the backup process if there is one and
calls the ABEND or PROCESS_STOP_ procedure. 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.
