pageview.datfiles to a Database Store
As of Release 8, DLXS Text Class middleware employs standard database mechanisms for
storing page-level metadata (an improvement for scalability and
management from the legacy
pageview.dat file mechanism). DLXS encourages
participants to move away from this legacy mechanism, and is currently working toward
release of a utility that can be used during digitization to populate the database
store directly as metadata is generated.
In the meantime, to help
transition materials that are using the legacy mechanism, we've
supplied a utility to copy metadata from
pageview.dat files into the
database store (the Pageview table in the DLXS database) used by Text Class.
bin/t/text/importpageviewdata.pl can be run once
(for a one-time cutover) or on a regular basis via
cron or your preferred
scheduling utility (for situations where
pageview.dat files are still being maintained and updated).
The syntax is
importpageviewdata.pl -d [directory] [-f]
[directory] argument specifies the directory to crawl for
If there is more than one, use
"directory1 directory2 directory3 ...",
with the quotes.
Directories may be excluded from crawling (for performance or other reasons) by creating files named
.importpageviewdata.skip directly inside them. There is no limit on the number of directories that may be skipped using mechanism.
[-f] argument specifies a "full" run. If used,
the recorded time of the previous run is
ignored, and all
pageview.dat files are processed regardless of their
age. Without this argument, the utility runs in a "maintenance" mode,
copying only metadata changed since the last run to the database store
to increase performance and reduce database fragmentation and load.
importpageviewdata.pl will automatically use the database, user, and
password that you entered when installing Text Class. If you manually
change these configurations in Text Class,
honor the changes and connect using the new parameters.
