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
