Configuring Informix Log Backups

You must configure both TAPEDEV and LTAPEDEV to a value other than the default value of /dev/null for Informix backups and restores to work.

Procedure

1. Edit the following file :

   #vi $INFORMIXDIR/etc/$ONCONFIG

2. Change the location in TAPEDEV and LTAPEDEV parameters from /dev/null on Unix computers and NUL on Windows computers to any non-existing directory to which you as an Informix user have full access rights to perform log backups.

   Example:

   UNIX

   TAPEDEV /dev/null
    LTAPEDEV /dev/null
   

   Change to:

   TAPEDEV /dev/tmp0
    LTAPEDEV /dev/tmp1
   

   Windows

   LTAPEDEV NUL
   Change to:

   LTAPEDEV C:\Program Files\IBM\Informix\tape1
   

3. Start a full backup.
