onbar -r -w -p erroring out

Hi, I'm executing onbar -r -w -p, I recieve the following messages in my bar_activity log. ERROR: Unable to write restore data to the database server: could not fork server connection. and also, ERROR: Unable to write restore data to the database server: not enough memory. Please if anyone has seen this type of error or has some knowledge on this, do help. Thanks, Kiran.

Hi, I assume you are doing a cold restore, i.e. the server is not running at the time ... (Otherwise I guess that this is your problem: you can't do a cold restore while the server is up.) While the error messages may not be very descriptive of the problem cause, it means that there is a shortage of resources. In this case it points quite clearly to a memory shortage. On-Bar requires the creation of certain SHM segments that are used to communicate with the IDS server that will be started during the restore process. Additional SHM segments are created and used to transport the archive data from the Storage Manager to the IDS server (which then writes the data to disks). The error message suggests that there is not enough memory available to processes for these operations. Reasons for this shortage can be various, like not enough physical memory, not enough swap space, kernel parameters not big enough to let processes create/attach to SHM segments of the size or in the number required. To find out more, check the online message log file (e.g. if the IDS server is started at all or the failure occurs before the IDS server is started). If nothing else helps, you can try to trace system calls of "onbar_d" (started via "onbar") and the children it forks off during the process. Use a system utility like "truss" or "strace" (name and availability depends on your platform). Though I don't think you'll have to go that far.
