Configuring data logging

7–25
In all other cases, RSView32 checks whether the primary path has
become available after the specified time has elapsed.
Minimum free disk space required for auto switchback (MB)
For data log models that use dBASE IV storage format, specify an
amount that is high enough to prevent RSView32 from frequently
switching between paths due to low disk space on the primary
path. The needs of your project may vary considerably from the
default value of 10 MB, depending on the frequency and amount
of data you expect to log. This option is not available if you use the
ODBC storage format.
Note that RSView32 does not use this amount to trigger a switch
to the secondary path. The amount is used only to determine
whether to switch back automatically to the primary path after the
time to retry has elapsed.
Using the DataLogSwitchBack command to switch
logging paths
You can switch back to the primary path manually by using the
DataLogSwitchBack <file> command or DataLogSwitchBack *
command.
The DataLogSwitchBack <file> command switches logging for the
specified data log model. The DataLogSwitchBack * command
switches logging for all data log models that are currently running. Use
these commands anywhere an RSView32 command or macro can be
entered. For example, type the command as the action for an event.
These commands perform a switchback only if the model is running,
RSView32 is logging data to the secondary or backup path, and the
primary path or ODBC database is available. For .dbf files, RSView32
creates a new set of files when it switches back to the primary path.
In order to prevent an impact on performance, data is not moved
from the secondary or backup path when you switch back to the
