Offline data capture

Question

HI..
I have created the .dat files, using the offline capture scripts.
From the capture wizard, I clieck offline capture, provide it the files.. window appears which says it is loading the source model.
After everything is done, I cannot see anything in the souce model on the main pane of the workbench. It says no objects captured. There were no errors in the log file. I am using the default repository..
any clue, on how to fix this.

HI Manoj,
I think your problem may be delimiters.
The column and row delimiter used to seperate out the columns and rows of data in the dat file, the same characte ris also present in the data itself.
Sybase 12 by default uses
OFFLINE_CAPTURE_COLUMN_DELIMITER=§
OFFLINE_CAPTURE_ROW_DELIMITER=¥
I think your data may contain one of those characters somewhere. So when the OMWB comes to read the dat files it mistakenly thinks there is an extra column or row.
To solve this problem you can change the column and row delimiters used.
1) Change the delimiter in the offline capture scripts and then rerun them to generate data files with the new delimiteres
- omwb\offline_capture\Sybase12\OMWB_OFFLINE_CAPTURE.BAT
I would change this
rem ** SET THE VALUE FOR THE OFFLINE_CAPTURE_COLUMN_DELIMITER
rem ** THIS VALUE SHOULD MATCH THE VALUE SET FOR THE SAME VARIABLE IN OMWB_INSTALL_DIR\bin\omwb.properties
set OFFLINE_CAPTURE_COLUMN_DELIMITER=§
rem ** SET THE VALUE FOR THE OFFLINE_CAPTURE_ROW_DELIMITER
rem ** THIS VALUE SHOULD MATCH THE VALUE SET FOR THE SAME VARIABLE IN OMWB_INSTALL_DIR\bin\omwb.properties
set OFFLINE_CAPTURE_ROW_DELIMITER=¥
to this
rem ** SET THE VALUE FOR THE OFFLINE_CAPTURE_COLUMN_DELIMITER
rem ** THIS VALUE SHOULD MATCH THE VALUE SET FOR THE SAME VARIABLE IN OMWB_INSTALL_DIR\bin\omwb.properties
set OFFLINE_CAPTURE_COLUMN_DELIMITER=º
rem ** SET THE VALUE FOR THE OFFLINE_CAPTURE_ROW_DELIMITER
rem ** THIS VALUE SHOULD MATCH THE VALUE SET FOR THE SAME VARIABLE IN OMWB_INSTALL_DIR\bin\omwb.properties
set OFFLINE_CAPTURE_ROW_DELIMITER=Ñ
These 2 characters occur very little in real data, so they are the next best choice of character for delimiters. But you can use any one you want. (has to be a single character though)
2) Next you have to tell the OMWB what delimiter characters to expect
a.
Using a text editor, open the omwb.properties file located in the OMWB_install_dir/Omwb/bin directory. If it doesnt exits, create a new file called omwb.properties
b.
Edit or add the following fields:
OFFLINE_CAPTURE_COLUMN_DELIMITER="º"
OFFLINE_CAPTURE_ROW_DELIMITER="Ñ"
In the previous lines, delimiter_column is your choice of column delimiter and delimiter_row is your choice of row delimiter.
c.
Save the file, then exit.
Migration Workbench is now enabled to handle the new character encoding.
You can try and load up your captured database now.
I hope this works,
Dermot.
