Onbar Backup?

Hi, I am running Level-1 backup on IDS 9.4.UC1 ,SunOS 8. My question is even though multiplexing is on and set to 8 in the onconfig as well as on the Netbackup side. (Veritas Storage Manager ), the Level-0 backups take about 12 Hours to complete for backing up 90 dbspaces. Each dbspace is about 2 GB in size. Secondly, when I want to look at stack output for the threads running the backups, in "onstat -g ath" output, I donot see arcbackup thread but instead 9 ontape backup threads. Hence, not able to determine if we are hitting the old arc_very_old_pages bug. Moreover, in the infx_db_comm directory under /usr/openv/netbackup... directory, the output for the storage Manager ID for e.g :does show that may be even multiplexing is not working: fsaatdw1 $more infxbsa.1057670308.27198.1 08:18:31 Initiating backup 08:19:27 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:20:12 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:21:01 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:21:53 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:22:37 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:23:22 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:24:06 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:24:50 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:25:35 INF - Waiting in NetBackup scheduler work queue on server kcax09 08:26:18 INF - Starting bpbrm 08:26:21 INF - Data socket = kcax09.IPC:/tmp/vnetCDVx7a 08:26:21 INF - Name socket = kcax09.IPC:/tmp/vnetCDVx7b 08:26:21 INF - Frozen image = 0 08:26:21 INF - Backup copy = 0 08:26:22 INF - Master server = kcax09 08:26:22 INF - New data socket = kcax09.IPC:/tmp/vnetCr.YEa 08:26:22 INF - Backup id = eclipse_1057670970 08:26:22 INF - Compression = 0 08:26:22 INF - Backup time = 1057670970 08:26:23 INF - Encrypt = 0 08:26:23 INF - Multiplexing = 8 08:26:23 INF - Client read timeout = 900 08:26:23 INF - Media mount timeout = 0 08:26:37 INF - Beginning backup on server kcax09 of client eclipse. 08:27:21 INF - Server status = 0 08:27:24 INF - Server status = 0 08:27:28 INF - Backup by informix on client eclipse: the requested operation was successfully completed. Does anybody know to overcome this issue ? Thanks in advance. Venaktesh Konnur
