Re: [Networker] critical problem .. help me

Hi, 

please, verify your setting of tape device configure

However, I am not sure where True64 has stored this information.  This 
information is from Legato Error Messages.  What the important. 
Default, networker uses 64kB block size, the tape drive hasn´t strict set 
of block size /the block size is managed by OS or software/. 
Therefore, check this setting on your system....


DLT8k -data = 1, 0x36, 0, 0x8219, 4, 0x82, 0x83, 0x84,
0x85, 3;
By changing the block size, this entry becomes:
DLT8k-data - 1, 0x36, 64, 0x8219, 4, 0x82, 0x83, 0x84,
0x85, 3;

Messages: V
• If the volume was created using an existing configuration, set the block
size in the st.conf file equal to the SCSI controller’s block size limit. 
To
determine the block size limit, use the mt command. For example, if the
SCSI block size limit is 64k, change the block size entry in the st.conf 
file to
64.

        Předmět:        critical problem .. help me


Server : compaq5.1 (tru64 cluster Oracle Server)
Networker 6.1 (build 186) network/10
Tape Library : compaq (DLT8000) 2drives
device name : /dev/ntape/tape6_d1
/dev/ntpae/tape7_d1

I back up Oracle Cluster datafile. Datafile size is 300Gbytes
Oracle script is used for oracle backup in savepnpc.
the script is easy coding by ksh shell

ora-begin.sh
------------

#!/usr/bin/ksh
svrmgrl << EOF
connect internal
alter database system begin backup ;
alter database user1  begin bakcup;
...
...
...
<< EOF

ora-end.sh
-----------

#!/usr/bin/ksh
svrmgrl << EOF
connect internal
alter database system end backup ;
alter database user1  end bakcup;
...
...
...
<< EOF


Oracle backup group is Oracle
this group's savepnpc is in /nsr/res/Oracle.res
this file consist next syntax
precmd: "/nsr/script/ora-begin.sh"
pstcmd: "/nsr/script/ora-end.sh"
timeout "12:00:00"

Oracle backup started from auto schedule.
Oracle Backup progressed normally.
But before backup is end pstcmd is running and ora-begin shell is started
this happen in 06:00, backup'end time is 08:00
Why pstcmd is running before backup is end ?
backup result in sucess but this data can't recover . because
ora-end.sh is runned before backup is end.
help me ...

and i show messages in /nsr/logs/daemons.log, messages

Block size is 32768 bytes not 98304bytes, verify the device configuration
tape positioning by record is disabled

what's mean ?
