Operating OnLine

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 from tbtape ask you to specify the archive level.

Follow the prompts for labelling and mounting new tapes. A
message informs you when the archive is complete. For further infor-
mation about the tbtape utility, refer to

If the logical log files fill during an archive, OnLine displays a message at the
system console and normal processing is suspended.

If you have two tape devices available to OnLine, log in as user informix at
a free terminal.

Verify that

LTAPEDEV

 and

TAPEDEV

 specify different pathnames that corre-

spond to separate tape devices. If they do, back up the logical log files by
executing either tbtape -a or tbtape -c, or by selecting either the Automatic-
Backup or Continuous-Backup option from the Logical-Logs menu.

If

LTAPEDEV

 and

TAPEDEV

 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

earlier logical log file backups. (All tapes must reflect the physical character-
istics specified 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.
