ixbar file layout. IDS 7.31.FC6x2 on Solaris 2.7

Hi,
Anybody intimately familiar with the ixbar (onbar emergency boot file)
file layout?
I am IDS 7.31.FC6x2 on Solaris 2.7 using Veritas Netbackup as my onbar
partner.
There was a problem with the netbackup server last night.
When the problem was fixed (server reboot), the handshake from my
database to the netbackup server started working again. My onbar
logical log backup was aborting during the netbackup server problem.
Once the handshake was restored, onbar started backing up the logical
logs again.
the first log (940776) that failed to back up when the problem hit, did
back up this morning as noted in the online.log. However in ixbar, the
log backup for this log did not show up in numerical/time sequence order
which is the norm in the ixbar file.
Also the ixbar file fields for this log are not the 'norm', plus this
log backup does not appear in the sysutils bar_* tables.
I may or may not have an opportunity to test what would happen if I
tried to restore this logical log.
Below are sample ixbar records from my system. the first and last
records indicate successful backups (properly recorded in systutils and
ixbar), the second entry is the 940776 goofy log. Notice the difference
in records is that log 940776 has a "0" in the last field, whereas the
others do not.
Anyone have a clue what that last field is for and if it is important to
any restore?
(yes, my example does not show 940776 out of order, but it's just my
example)...

Hi,
The last field is "required action id" (column 13).
For logical log backups "required action id" is same
as "action id" field (column 5).
The "required action id" is associated with incremental backups.
Since, there are no incremental logical log backups, this field is
not used for logical log backup objects.
So, restore should be fine.
Thanks,
Paresh.
