Operating OnLine 3-59
If the Logical Log Files Fill During an Archive
3. Place a write-enabled tape on the tape drive device (defined by
TAPEDEV). Put the device online with the appropriate operating-
system command.
The prompts fromtbtape ask you to specify the archive level.
4. Follow the prompts for labelling and mounting new tapes. A
messageinforms you when the archive is complete. For further infor-
mation about the tbtape utility, refer topage 7-102.
If the Logical Log Files Fill During an ArchiveIfthe logical log files fill during an archive, OnLine displays a message at the
system console and normal processing issuspended.
Two Tape Drives
If you have two tape devices available to OnLine, log in as userinformix at
a free terminal.
Verify thatLTAPEDEV and TAPEDEV specify different pathnames that corre-
spond to separate tape devices. If they do, back up the logical log files by
executing eithertbtape -a or tbtape -c, or by selecting either the Automatic-
Backup or Continuous-Backup option from the Logical-Logs menu.
If LTAPEDEV andTAPEDEV are identical, you might be able to assign a
different value to the logical log tape device (LTAPEDEV) and initiate logical
log file backups. However, this option is only a solution if the new value of
LTAPEDEV is compatible with the block size and tape size used to create
earlierlogical log file backups. (All tapes must reflect the physical character-
isticsspecified at the time of the most recent level-0 archive.) Otherwise, your
options are to either leave normal OnLine processing suspended until the
archive completes or cancel the archive.
