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!

Martin's got the direct answer covered. The indirect answers are:
1- Increase your logical log size so that it's not backing up so
frequently.
2- Do your test during a quieter period for the server.

Thanks Martin and Kagel,
I'm working in increase the size of the logical log files,
creating a separate pool at Tivoli, and reducing the BAR_MAX_BACKUP
parameter
to 5. I also changed the buffer mode to buffered instead of
unbuffered.

The only problem it's that at this server I really don't have a
quieter period,
it receives traps from a telecom network and it don't have a time for
even breath!

Thanks guys, I'll let you know about my progress!
The next step will be restore this backup in a IDS 10, enviroment,
which is already ready for the data.

Regards,
Guto

Thanks again Martin,
I'll do it, or even run a dbexport/dbimport.
Thanks indeed.!
Guto.
