You can change the transaction log file of a database with toolkit as follows:
Start toolkit on your database:
c:\> toolkit dbname
Select 6 - Database Menu from the Toolkit Development Menu.
Select D4 - Define/Change Database Logfile from the Database Menu.
Enter the new log file name and press STORE <F5>, or press CANCEL <F1>-X to leave the old log file name unchanged. The file name you enter must be either an absolute pathname, or a pathname relative to the home directory of the database.
After you press STORE <F5>, toolkit creates a new, empty log file and updates the database catalog.
You can change the log file name of a database with the following commands:
c:\> makelog logpath
c:\> dbadmin -vu -L logpath dbname
The log file name, logpath, must be either an absolute pathname, or a pathname relative to the database home directory. The makelog command insures that logpath names a new, empty transaction log file.
