GOAL:
Word-break Table Problem and Workaround for V9
FACT(s) (Environment):
Progress 8.X
Progress 9.X
SYMPTOM(s):
Word-break Table
CAUSE:
Progress introduced a new format for the word-break table in Version 9, with the intention to support both the old (Version 8) and the new formats of these tables.
A mistake in the detection of the Version 8 word break tables led to a usage problem. That is, the information in the version 8 table is not interpreted correctly. This problem occurs only for those users who:
a) have created their own word break tables in version 8, AND
b) continue to use them with version 9 without converting to the version 9 format.
Two symptoms of the problem are:
1) An error is detected on connection and you cannot connect to the database.
or
2) You can connect, and updating the database can lead to a corrupt word-index.
FIX:
The solution is to convert the Version 8 word break table to a Version 9 word break table.
1)As opposed to simply adopting one of the existing tables provided in dlc/prolang/convmap, the version 8 wordbreak table must be edited to include the following information at the head of the file:
version = 9
codepage = <codepagename>
wordrules-name = basic
type = 2
(substitute your database codepage for "<codepagename>", typically "codepage=iso8859-1").
There are several examples of v9 format wordbreak tables in dlc/prolang/convmap/*.wbt.
2) Next, compile the word break table with "proutil -C wbreak-compiler command and assign it to the database with the "proutil -C word-rules" command.
We recommend running an index build to insure the index is now correct.
