backup. For more information, go to this location:

If you are using the Oracle database, you need to install the Oracle JDBC (Java Database Connectivity)
component for Fabric Manager to connect to the database. For more information refer to the
Database Connectivity" section on page

Increasing UDP Buffer Size

If the Fabric Manager SNMP packet log shows an SNMP VarBind decode error, the UDP buffer size is
low and the buffer size needs to be increased.
To increase the UDP buffer size, do the following:
For Solaris 8, ensure that the UDP buffer size is at least 64 K.
Step 1
ndd -set /dev/udp udp_recv_hiwat 65535
ndd -set /dev/udp udp_xmit_hiwat 65535
Step 2 Add the following setting in /etc/system, so that the buffer size will be in effect even after a reboot.
set ndd:udp_recv_hiwat=65535
set ndd:udp_xmit_hiwat=65535
Before starting the installation, make sure that you have logged in as a Superuser.
Note

Database Backup and Restore-PostgresSQL

The Fabric Manager uses PostgresSQL Database as the default database. The Fabric Manager backup
utility uses PostgresSQL pg_dump utility to dump all of the database content to an ASCII dump file.
Restore utility uses PostgresSQL to recreate data using the dump file.
The dump file represents a snapshot of the database at the time of backup.

Backup

To perform a backup of the Fabric Manager database, enter these commands on Linux/Solaris. Assume
INSTALLDIR is the top directory of Fabric Manager installation.
cd $INSTALLDIR/bin
/pgbackup.sh 02252008.data
The backup file 02252008.data will be created in $INSTALLDIR/bin directory. If you want to create it
in a standard backup director provide the full path name of the dump file
