Legato Single Server Version (LSSV) 7.1 and RMAN on Tru64 5.1bLegato Single Server Version (LSSV) 7.1 is shipped on the Oracle Database 10g Companion CD, allowing RMAN to write to tape as well as disk.

OUI InstallAs the Oracle software owner move to the "Oracle Database 10g Companion CD" staging area, export the DISPLAY variable if necessary and start the installer.

cd /ccd/Disk1
export DISPLAY=clientpc:0.0
./runInstaller

Install the companion products into an existing database ORACLE_HOME. When prompted run the $ORACLE_HOME/root.sh script as root which installs the LSSV software.Add "/usr/opt/networker/bin" to the PATH variable in the root .profile file.
Manual InstallAs the root user move to the "Oracle Database 10g Companion CD" staging area, find the appropriate lsminst script and run it as follows.

su - root
cd /ccd
find . -name lsminst
-print
./Disk1/lgto/lsminst
./Disk1/stage/Components/oracle.rdbms.lsm/6.1.0.0.0/1/DataFiles/Expanded/lsm/lsminst
./Disk1/stage/Components/oracle.rdbms.lsm/6.1.0.0.0/1/DataFiles/Expanded/lsminst
./Disk1/stage/Components/oracle.rdbms.lsm/6.1.0.0.0/1/DataFiles/Expanded/lsminst/rdbms/install/lgto/lsminst
cd
./Disk1/stage/Components/oracle.rdbms.lsm/6.1.0.0.0/1/DataFiles/Expanded/lsm/
./lsminst ./stage_tmp/lsm

During the installation you will be asked several questions, most of which can be answered with the defaults with the exception of the following:

Select option 2 (Install LSSV Software)
Select option 5 (Install all
subsets)
Enter the server name to backup.

Only move on to the next stage if the installation was completed successfully.As the Oracle software owner find the liblsm.so library in the staging area, copy it to the appropriate location and create a symbolic link to it.

su - oracle
cd /ora/install/db/10.1.0/ccd
find . -name liblsm.so
-print
./Disk1/stage/Components/oracle.rdbms.lsm/6.1.0.0.0/1/DataFiles/Expanded/lsminst/lib/liblsm.so
cd
./Disk1/stage/Components/oracle.rdbms.lsm/6.1.0.0.0/1/DataFiles/Expanded/lsminst/lib/
cp
liblsm.so $ORACLE_HOME/lib/liblsm.so
ln -s $ORACLE_HOME/lib/liblsm.so
$ORACLE_HOME/lib/libobk.so

Add "/usr/opt/networker/bin" to the PATH variable in the root .profile file.
Manual Uninstall

To manually uninstall the Legato software do the following.

su - oracle
cd $ORACLE_HOME/lib
rm liblsm.so
rm libobk.so
su -
root
nsr_shutdown
# Select the appropriate line depending on the
version.
#setld -d ORCLSERV610 ORCLNODE610 ORCLCLNT610 ORCLMAN610
#setld
-d LGTOCLNT611 LGTOMAN611 LGTONODE611 LGTOSERV611
setld -d LGTOSERV710
LGTONODE710 LGTOCLNT710 LGTOMAN710

Networker

The Networker software can be accessed by issuing the following command as the root user.

export DISPLAY=clientpc:0.0
networker

Once the GUI has run you can use it to define devices, label and mount tapes etc. The scripts used later assume that the necessary tape devices have been defined and the tape being mounted is already labelled.
RMAN Tape Backups

Once the LSSV software is installed RMAN backups to tape can be done by defining the default device type as follows.

su - oracle
rman target=/
Recovery Manager: Release 10.1.0.2.0 -
Production
Copyright (c) 1995, 2004, Oracle. All rights
reserved.
connected to target database: DEV (DBID=3608529853)
RMAN>
CONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE';
old RMAN configuration
parameters:
CONFIGURE DEFAULT DEVICE TYPE TO DISK;
new RMAN configuration
parameters:
CONFIGURE DEFAULT DEVICE TYPE TO 'SBT_TAPE';
new RMAN
configuration parameters are successfully stored

Once this parameter is defined RMAN uses the libobk.so library as the media manager by default. In this way RMAN is able to work with any supported third party media manager by simply creating a symbolic link called libobk.so which points to the vendors media management library, in this case liblsm.so.A tape backup can be done using a script like the following which is run from root.

#!/bin/ksh
PATH=$PATH:/usr/bin:/usr/sbin/:/sbin:/bin:/usr/opt/networker/bin;
export PATH
ORACLE_BASE=/u01/app/oracle; export
ORACLE_BASE
LOGPATH=$ORACLE_BASE/dba/logs; export
LOGPATH
LOGFILE=$LOGPATH/daily_backup.0.log; export LOGFILE
# Rotate
logs.
rm $LOGPATH/daily_backup.9.log
mv $LOGPATH/daily_backup.8.log
$LOGPATH/daily_backup.9.log
mv $LOGPATH/daily_backup.7.log
$LOGPATH/daily_backup.8.log
mv $LOGPATH/daily_backup.6.log
$LOGPATH/daily_backup.7.log
mv $LOGPATH/daily_backup.5.log
$LOGPATH/daily_backup.6.log
mv $LOGPATH/daily_backup.4.log
$LOGPATH/daily_backup.5.log
mv $LOGPATH/daily_backup.3.log
$LOGPATH/daily_backup.4.log
mv $LOGPATH/daily_backup.2.log
$LOGPATH/daily_backup.3.log
mv $LOGPATH/daily_backup.1.log
$LOGPATH/daily_backup.2.log
mv $LOGPATH/daily_backup.0.log
$LOGPATH/daily_backup.1.log
echo "Log rotate complete" >> $LOGFILE
2>&1
echo Start: `date +"%d/%m/%y %H:%M"` >> $LOGFILE
2>&1
chmod 777 $LOGFILE
# Mount the tape
nsrmm -m -f
/dev/ntape/tape0_d1 >> $LOGFILE 2>&1
sleep 240
su - oracle
<ORACLE_SID=DEV1; export ORACLE_SID
rman target=/
cmdfile='$ORACLE_BASE/dba/cmdfile' log='$LOGFILE' append
EOF
# Unmount the
tape
nsrmm -u >> $LOGFILE 2>&1
echo End: `date +"%d/%m/%y
%H:%M"` >> $LOGFILE 2>&1

The "cmdfile" referenced by this script constains the following RMAN script.

run {
backup database plus archivelog;
delete force noprompt
obsolete;
}
exit;

Obviosuly you will need to adjust any path and device names appropriately.For further information see:
