Operating OnLine 3-57
Create an Archive, Any Type
From the Command Line
1. To change the value of TAPESIZE from the command line, use an
editor to edit the file specified by $INFORMIXDIR/etc/$TBCONFIG.
2. Change the value of TAPESIZE to the new tape size, expressed in
kilobytes.
Create an Archive, Any Type
An archive can require multiple tapes. After a tape fills, OnLine rewinds the
tape, prompts the operator with the tape number for labelling, and prompts
the operator again to mount the next tape, if one is needed.
Preliminary Considerations
You can create an archive while OnLine is in online or quiescent mode.
Each time you create a level-0 archive, also create a copy of the OnLine
configuration file as it exists at the time that the archive begins. You will need
this information if you must restore OnLine from the archive tape.
If the total available space in the logical log files is less than half of a single
log file, OnLine does not create an archive. Back up the logical log files and
then request the archive again.
You cannot add a logical log file or mirroring during an archive.
If only one tape device is available on your system, refer to page 3-49 for
more information about the steps you can take to reduce the likelihood of
filling the logical log during the archive.
The terminal from which you initiate the archive command is dedicated to
the archive (displaying messages) until the archive is complete.
If you are logged in as user informix, you can create any type of archive from
within DB-Monitor or from the command line. If you are logged in as root,
you must use the command-line option.
