ixbar file: ON-Bar emergency boot fileThe emergency boot file is automatically updated after every backup. It contains the information that ON-Bar needs to perform a cold restore.

ixbar file: ON-Bar emergency boot file

The emergency boot file is automatically updated after every backup. It contains the information that ON-Bar needs to perform a cold restore.

Important: Do not modify the emergency boot file. Doing so might cause ON-Bar to select the wrong backup as part of a restore, possibly leading to data corruption or system failure.

The file name for the boot file is ixbar.servernum, where servernum is the value of the SERVERNUM configuration parameter.

The ON-Bar emergency boot file is in the $INFORMIXDIR/etc directory on UNIX™ and in the %INFORMIXDIR%\etc directory on Windows™. You can override the default path and name of the boot file by changing the information specified in the BAR_IXBAR_PATH configuration parameter.
