StorageTek Proprietary
WRITETIMEOUT parameters. The command may be abbreviated to the
single character 'S'.
The values of MAXTRDR, MAXDRDR, MAXSCHED, MAXQLEN,
RETAINTAPE, TAPEWAIT, OBJSIZE, READTIMEOUT and
WRITETIMEOUT are initially set during DB2 Manager control region
initialization from the corresponding parameters in the TAPECNTL and
ENVCNTL members of the DB2 Manager parameter library.
Valid parameters for the SET command are:
MAXTRDR - DB2 Manager will alter the current setting of the
MAXTRDR parameter to the value specified in the SET
command. The value ‘nnn’ must be a 1-3 digit numeric
value in the range 0-255.
If the value of MAXTRDR is to be increased, DB2 Manager
will increase the number of initialized tape reader tasks, by
restarting terminated tasks, and/or adding new tasks.
If the value of MAXTRDR is to be decreased, DB2
Manager will terminate a number of existing tasks equal to
the decrease in the value of MAXTRDR. These tasks will
appear with the status TERM in any subsequent status
display, and will not be available for object recall
processing.
Note that processing of this command may take a little
time for significant changes in the value of MAXTRDR.
MAXDRDR - DB2 Manager will alter the current setting of the
MAXDRDR parameter to the value specified in the SET
command. The value ‘nnn’ must be a 1-3 digit numeric
value in the range 0-255.
If the value of MAXDRDR is to be increased, DB2 Manager
will increase the number of initialized disk reader tasks, by
restarting terminated tasks, and/or adding new tasks.
If the value of MAXDRDR is to be decreased, DB2
Manager will terminate a number of existing disk reader
tasks equal to the decrease in the value of MAXDRDR.
These tasks will appear with the status TERM in any
subsequent status display, and will not be available for
object recall processing.
Note that processing of this command may take a little
time for significant changes in the value of MAXDRDR.
MAXTWTR - DB2 Manager will alter the current setting of the
MAXTRDR parameter to the value specified in the SET
command. The value ‘nnn’ must be a 1-3 digit numeric
value in the range 1-255.
