1 – Make sure that the TNS_ADMIN and
ORATAB environment variables have correct entries.
2 – Make sure that the
AUTOMATIC_IPC=OFF
parameter is in the SQLNET.ora.
3 – Make sure that the account
DBSNMP/DBSNMP
was created.
4 - Run root.sh. This will cause the
dbsnmp executable to be own by root and to set the setuid bit.
5 – Make sure that all the keywords in your LISTENER.ORA and TNSNAMES.ORA files are all in
UPPERCASE.
6 – Make sure that the value returned when issuing the UNIX command "hostname" matches
the TNSNAMES.ORA
reference to host.
7 - Ensure that the /etc/hosts file contains the hostname.
8 - Relink the agent executable:
% cd $ORACLE_HOME/network/lib
% make -f ins_agent.mk install
9 - Delete the $ORACLE_HOME/network/admin/SNMP_*.ORA files. Delete all the files in the
$ORACLE_HOME/network/agent
directory, leaving only the subdirectories.
10 - Set the environment variable: ORATAB & TNS_ADMIN
setenv ORATAB /etc/oratab or /var/opt/oracle/oratab <--use the exact oratab location
setenv TNS_ADMIN /u04/oracle/network/admin <--use the exact location of sqlnet config files.
11 - Verify that the ORATAB file contains only valid SIDs and ORACLE_HOMEs. Invalid entries in the
ORATAB file causes the Oracle Intelligent Agent not to start.
12 - Remove/rename all files in your $ORACLE_HOME/network/log directory. Files owned by root may
cause problems.
Good Luck!
