Date differences between .db and .bi
** The database was last used <date/time>. (886)
** The before-image file expected <date/time>. (887)
** Those dates don't match, so you have the wrong copy of one
of them (888)
This KB explains how Progress uses dates on startup.
"There are two kinds of dates, the operating system maintained
dates on the files, and internal dates that are stored in the
headers of each file.
The operating system maintains its dates and we do not care what they
are.
The database manager maintains internal "last opened" dates for
extents and writes the same value to each of them when the
database is opened (except when opened for read-only). These dates
must all match when the database is first opened.
There is additional checking to compare the bi file's last opened
date with the master block's copy of the same date value."
