Troubleshooting: Specific Problems
Description B ITO connects to Oracle as user opc_op using OS authentication. Oracle
allows you to define a prefix for OS authentication users. ITO adds the
user opc_op with the assumption that no prefix is used. If you have
defined a prefix, ITO will be unable to connect.
Solution A Check that the file
/etc/oratab
exists. Check that
/etc/oratab
is
readable by user opc_op. Check that
/etc/oratab
contains a line with
your ORACLE_SID. Check that user opc_op is properly setup.
Solution B If no other users of the database use OS authentication, you can change
the prefix:
• Add or change the line defining the prefix in the file:
${ORACLE_HOME}/dbs/init${ORACLE_SID}.ora
os_authent_prefix = ““
• Stop all processes accessing the database
• Restart the Oracle database. The new prefix is now active. If other
users also use OS authentication, you can change the prefix used by
ITO as follows:
• Destroy the ITO specific parts in the database using:
opcdbsetup -r
• Change the following line in the ITO database setup script
/opt/OV/bin/OpC/opcdbsetup
to contain the actual value:
OS_AUTHENT_PREFIX=””
• Setup the ITO database again using
opcdbsetup
