Lazy IDS Onbar Backup

Hi All! I'm trying to make a 23Gb Level 0 Backup of a IDS 9.20UC2 instance, testing the new Tivoli Backup System, but I'm facing this issue: The dbspaces backup starts fine, but then comes the logical log backups ( one per minute ) that are fullfilled so fast, and the Tivoli stops the dbspace backup in order to backup the logs. With it, I'm not able to make a backup of the dbspaces. Here's my configs: Informix Dynamic Server 2000 Version 9.20.UC2 BUFFERED LOG TAPEBLK 16 # Tape block size (Kbytes) TAPESIZE 24000000 # Maximum amount of data to put on tape (Kbytes) LTAPEBLK 512 # Log tape block size (Kbytes) LTAPESIZE 2000000 #Max amount of data to put on log tape (Kbytes) LOGFILES 160 # Number of logical log files LOGSIZE 3000 # Logical log size (Kbytes)CCFLAGS 0x400000 #ARCHIVE PARAMETER BAR_ACT_LOG /var/tmp/informix_backup_logs/bar_act.log BAR_DEBUG_LOG /var/tmp/informix_backup_logs/bar_dbug.log BAR_BSALIB_PATH /opt/tivoli/tsm/client/informix/bin/libTDPinf.so TAPEDEV /usr/informix/rawmsg/backup_devices/tapedev LTAPEDEV /usr/informix/rawmsg/backup_devices/ltapedev BAR_DEBUG 6 #( setted to 6 just to debug the problem ) BAR_MAX_BACKUP 10 BAR_RETRY 5 BAR_NB_XPORT_COUNT 1 BAR_XFER_BUF_SIZE 31 RESTARTABLE_RESTORE on BAR_PROGRESS_FREQ 0 Any suggestions are welcome! Thanks! Guto.- Brasil

Hi, make sure that you have setup Tivoli to use separate (different) volumes and pools for dbspaces and logs. This is the equivalent to the ISM_DATA_POOL and ISM_LOG_POOL onconfig parameters for ISM. Then make sure that Tivoli can access (i.e. write to) these volumes concurrently. I see that you have BAR_MAX_BACKUP set to 10. That means onbar will start 10 processes to backup 10 dbspaces in parallel. If this is too much for your Tivoli setup, then decrease this number to leave Tivoli some resources to also handle the log backup in parallel with the backup of dbspaces.
