Parallel Backups using onbar

I have some questions concerning parallel backups using onbar. We are running a large OLTP application on a SUN 10000 platform usint Informix 7.23. We are using onbar with Veritas Netbackup as the storage manager: When backing up logical logs, does onbar take advantage of parallel processing? It appears that logical logs are backed serially no matter what the setting of BAR_MAX_BACKUP. Also I find setting BAR_MAX_BACKUP to require a huge increase in shared memory. During my initial testing, I had the following setup: SHMTOTAL 1040000 # Total shared memory (Kbytes). 0=>unlimited # Backup/Restore variables BAR_ACT_LOG /tmp/bar_act.log BAR_MAX_BACKUP 5 BAR_DEBUG 7 BAR_DEBUG_LOG /tmp/bar_dbg.log BAR_RETRY 1 BAR_NB_XPORT_COUNT 10 BAR_XFER_BUF_SIZE 31 Page size is 2K When I increase BAR_MAX_BACKUP to 5, I got the following warning in bar_act.log: 1998-11-19 11:32:09 5448 5446 BAR_MAX_BACKUP has been reduced to 1 to avoid allocating more than SHMTOTAL KB I then increased shared memory: SHMTOTAL 2040000 # Total shared memory (Kbytes). 0=>unlimited I then saw the warning: 1998-11-19 15:14:07 29262 29259 BAR_MAX_BACKUP has been reduced to 3 to avoid allocating more than SHMTOTAL KB. It seems to me this is using a lot more memory then what the calculations call for. Any ideas? Thanks for your help. Its OK to respond via email.
