Re: Onbar backup problems

Hi, it occured to me also, that this could be a problem. So actually the error then has the meaning that you are somehow running out of some resource. I don't know about Windows, so I've no idea what this resource would be or why this then gets mapped to 154. With BAR_MAX_BACKUP set to 0 onbar will (try to) start as many processes as there are dbspaces to backup (after rootdbs has been backed up). Depending on your instance, this can be a lot of backup processes getting started. And apparently on your Windows machine "a lot" is a number around 8 ... There is no universal recommendation for the setting of BAR_MAX_BACKUP. The recommendation is to find out, how many parallel backup processes the system as a whole and the storage manager in particular can handle. (Seems to be around 8 on your system.) From this number you subtract 1 for logical log backup, because it can be triggered any time even during parallel dbspace backup. The resulting number is your recommended BAR_MAX_BACKUP setting.Now this is true for the IDS instance that utilizes the storage manager exclusively. If you utilize your storage manager for still other things (other IDS instance, possibly on a different machine, or some system backup tasks), then you may have to take these things into account as well.
