I seem to have got onbar working despite the shmdt:errno 22 messages. But when I looked in bar_act.log I discovered that I was getting a message telling me that the logical logs were full and I might have problems with updating sysutils. But when I checked my logs were nowhere near full. In fact the application isn't running, and the database is created with no logging. The process continued to backup just one logical log. I suspect the checks on full logs might not be working.
I then turned on BAR_DBUG at level 9 and obtained a complete log of the whole backup. To my amazement there seems to be no correlation between the times of the shmdt errors and the events in bar_dbug.log. The first shmdt error occurred at 12:46:05 but the first lline in bar_dbug.log is time 12:46:06 and is the onbar -b -L 0 line. It certainly seems to be the case that the shmdt errors precede begin and complete backp messages for the dbspaces by about 1 second.
I continue to investigate.
Any help, as always, is much appreciated.
Malcolm
