SECTION 7. DATA COLLECTION (DBSELECT)
7-6
FIGURE 7-4. Hole Collection View
hole of the specified range will be inserted into
the queue for each station in the network with
that table. Selecting one or more entries in the
hole queue and selecting the DELETE button
will remove the holes from the queue. This will
result in missing data if DBSelect added the
holes to the queue.
DBSelect will periodically check for a file named
AUTOHOLE.DAT. If this file exists, DBSelect
will add the holes contained in the file to its
queue of holes to collect. DBSelect will delete
the hole file after it adds the holes to the queue.
Section 8.3 describes the format for this file.
DBSelect Status
Selecting STATUS on the DBSelect main menu
displays information on disk space, rate of disk
usage, ASCII file baling, etc.
Multiple copies of DBSelect and command
line parameters
Under some conditions it may be desirable to
run two independent copies of DBSelect. When
two copies are run, the second copy MUST be
run in a separate directory and MUST use the
following command line parameters:
DBSelect name directory
where name is used to create the names for the
named pipes (acknowledged and unacknowledged)
associated with second DBSelect. Since named
pipes are global throughout OS/2 the second copy
must have different names even if the named pipes
are not being used. The acknowledged named pipe
"\PIPE\SECOND" uses the name as specified on
the command line. The unacknowledged named
pipe will use name with an 'a' appended to it. If
name were "SECOND" then the acknowledged
name pipe would be "SECOND" and the
unacknowledged would be "SECONDA".'
The directory specifies the directory where
DLSMGR can find its initialization files. This is
necessary when starting the second copy of
DBSelect that is not located in the main RTMS
directory. Each copy of DBSelect keeps its own
initialization files in their respective directories
but DLSMGR keeps its initialization files in the
directory of the program that started it. If the
second copy is started first at a later date,
DLSMGR will look in the second's DBSelect
directory for its files and not find them.
