When migrating databases from versions below Oracle 10g and especially if the users are recreated in the 10g databases with the privileges from the old version, certain privileges are required to be granted so that the application users can connect to the database with proper privileges. This article discusses this special case on the occurrence of ORA-01031 error in Oracle 10g databases.

The ‘CONNECT’ role in Oracle 10g has only ‘CREATE SESSION’ privilege, whereas the previous version had some additional privileges. If the privileges are missing, the user won’t be able to create objects which will result in ‘ORA-01031 insufficient privileges’ messages to the user.

To fix the issue, grant the 8 privileges listed below to the users.

In Oracle 9i, the CONNECT role had the following privileges:

SQL>  select * from dba_sys_privs  where grantee='CONNECT';

GRANTEE                        PRIVILEGE                                ADM
------------------------------ ---------------------------------------- ---
CONNECT                        CREATE VIEW                              NO
CONNECT                        CREATE TABLE                             NO
CONNECT                        ALTER SESSION                            NO
CONNECT                        CREATE CLUSTER                           NO
CONNECT                        CREATE SESSION                           NO
CONNECT                        CREATE SYNONYM                           NO
CONNECT                        CREATE SEQUENCE                          NO
CONNECT                        CREATE DATABASE LINK                     NO

8 rows selected.

In Oracle 10g, only the ‘CREATE SESSION’ privilege is granted to the CONNECT ROLE.

SQL>  select * from dba_sys_privs  where grantee='CONNECT';

GRANTEE                        PRIVILEGE                                ADM

Even patchset difference between the exp utility and the database can lead to similar issues.

The best bet to deal with the issue is to use the lowest version available at the source/target database.

If you are using Oracle client, opt for the lowest version available for taking the export.

The errors differ based on the version difference between exp utility and the database, the following errors are possible:

9i client against lower versions of 9i database or 10g clients against 9.2.0.4 database can cause the following messages in the export log:

EXP-00056 Oracle error 942 encountered
ORA-00942 table or view does not exist
EXP-00000 Export terminated unsuccessfully

On some 9i R2 versions, the error may be reported as below:

EXP-00008: ORACLE error 942 encountered
ORA-00942: table or view does not exist
EXP-00024: Export views not installed, please notify your DBA
EXP-00000: Export terminated unsuccessfully

9.2.0.6 export client against a 9.2.0.5 can cause the following messages in the export log during the export of partitioned tables.

EXP-00056: ORACLE error 6550 encountered
ORA-06550: line 1, column 48:
PLS-00302: component ‘CHECK_MATCH_TEMPLATE’ must be declared
ORA-06550: line 1, column 14:

10.2.0.4 client against a 10.2.0.3 database can cause the following messages in the export log during the export of operators.
