Warm Starting a Scheduler
•
To specify another log file instead of accepting the default, add map DEFINE
=_ZBAT_LOG_FILE to the TACL environment before running NETBATCH. For
example:
> ADD DEFINE =_ZBAT_LOG_FILE, CLASS MAP, FILE $ZTN0.#PTY6
> INFO DEFINE =_ZBAT_LOG_FILE
Define Name =_ZBAT_LOG_FILE
CLASS MAP
FILE \MELBDEV.$ZTN0.#PTY6
> NETBATCH /NAME $ZBAT, NOWAIT/ $NB.ZBAT
> BATCHCOM $ZBAT; STATUS SCHEDULER
SCHEDULER STATUS
Process : \MELBDEV.$ZBAT Primary : 0,60
Database: \MELBDEV.$NB.ZBAT
Logfile : \MELBDEV.$ZTN0.#PTY6 .
.
•
A scheduler-created disk log file adopts these attributes of the previous log if that
log was a disk file: primary and secondary extent sizes, maximum extents, buffer
size, expiration time, RWEP security, owner, and volume and subvolume.
•
If the scheduler’s log file prior to shutdown was not a disk file, the scheduler
automatically reopens that file when warm started. For example, a scheduler that
logs to $0 before being shut down continues logging to $0 when restarted.
Step 3: Start the Scheduler
To start the scheduler, use the START SCHEDULER command. The ALTER
SCHEDULER command in this example specifies the CPUs for the scheduler’s backup
process.
> BATCHCOM $ZBAT; ALTER SCHEDULER, BACKUPCPU 1,0
Scheduler altered
> BATCHCOM $ZBAT; START SCHEDULER
Scheduler started
> PPD $ZBAT
Name Primary Backup Ancestor
$ZBAT 1,52 0,50 $Z161
> FILEINFO $DATA7.ZBAT.*
