MODIFY JOURNAL

MODIFY JOURNAL
Specifies the desired and maximum allowed sizes of RTR's recovery journal.
Format
MODIFY JOURNAL [disk-1] ... [,disk-n]
Command Qualifiers
/CLUSTER
/BLOCKS=nr-blocks
/MAXIMUM_BLOCKS=nr-blocks
/NODE=node-list
/OUTPUT[=file-spec]
Description
The MODIFY JOURNAL command specifies how the size of RTR recovery
journal files on the specified disks can be modified. The
is specified using the /BLOCKS qualifier. The
using the /MAXIMUM_BLOCKS qualifier. /BLOCKS and /MAXIMUM_BLOCKS
are a positional qualifiers, so journal files need not be the same size on each disk.
RTR only uses journal files on nodes that are configured to run servers, that is,
on backends and on routers with call-out servers.
Note that the MODIFY JOURNAL command does not cause immediate journal
file extension. Actual file size modifications take place on demand (by the
RTRACP) within the limits defined by the MODIFY JOURNAL command.
The MODIFY JOURNAL command assumes that a journal already exists for the
node. If a journal does not exist, an error message is output.
In contrast to the CREATE JOURNAL command, the MODIFY JOURNAL
command is normally entered interactively, not automatically from a startup
command procedure.
Parameters
disk-1 ... disk-n
Specifies a list of disk names where journal files are modified.
Refer to the CREATE JOURNAL command for information about disks used for
journal files.
