The ROLL FORWARD statistic is the number of roll forward processes that are executing. A roll
forward process is started by the ROLL FORWARD command. It is used to roll transactions forward
from a post queue into the actual file for which that post had been queuing.
SHOW POST <import node> Command
The SHOW POST <import-node> command displays a list of all shadow files that the posting process
has open, including the status of the posting to each file. The following information is displayed:
Information Description
File
The name of the shadow file that is being updated by the posting process.
Type
The type of the shadow file. This field can have one of six values indicating
which type of file the posting process has opened. The value may be IMAGE,
MPE, KSAM, MSG or LOG indicating the type of file. If RIO is displayed in this
field, the file is a relative COBOL file. If the value of this field is ???, the
posting process was not able to open the file and consequently does not know
what the file type is.
Updates
The number of updates applied to this file since POST was last started.
Time
Stamp...
The time and date stamp of the record that was last processed. This time and
date reflects the time the transaction was created on the master system, not
the time that it was posted to the shadow copy of the file. If this time is
significantly in the past, it indicates one of two conditions. Either there is
currently a backlog of transactions, in which case the difference between this
time stamp and the clock of the master system will indicate a rough measure
of the shadowing time lag, or (more likely) there have been no transactions
made to this file since the time displayed.
SYN
This flag indicates that the shadow file is out of synchronization.
QUE
This flag indicates that updates to this file are being queued. If this field
displays Q, it indicates that a post queue has been created for this file. If this
field displays P, it indicates that the posting for this file has been deferred
with the DEFER command.
DIS
This flag indicates that updates are being discarded due to a serious error on
the file or a synchronization problem.
