SQLException with native SQL and regular DB user

Jun 03, 2004 at 08:44 AM | 5 Views

Hello *,

I've set up a datasource in the visual administrator to an external Oracle database, which works fine for vendor SQL. Native SQL works only if I use the DB system admin account. If I take a user with access rights only for the application's DB schema, I get an SQLException when I try to execute "dataSource.getConnection()" with the message

... ORA-00942: Tabelle oder View nicht vorhanden

(table or view not available)

It seems as if WAS tries to access tables outside the applications's schema on opening the connection.

What do I need to do to avoid this exception with native SQL and a restricted DB user?

Regards

Martin

      Hey Martin.

      If you haven't figured it out yet, here is the excerpt from an Oracle docs:

      "Connecting with Administrative Privileges: Example

      This example illustrates that a user is assigned another schema (SYS) when connecting with the SYSDBA system privilege.

      Assume that user scott has issued the following statements:

      CONNECT scott/password

      CREATE TABLE admin_test(name VARCHAR2(20));

      Later, scott issues these statements:

      CONNECT scott/password AS SYSDBA

      SELECT * FROM admin_test;

      User scott now receives the following error:

      ORA-00942: table or view does not exist

      This is because scott now references the SYS schema by default. The table was created in the scott schema.

      "

      So, I think, if you create a global synonym for your table you should be able to see it.

      create public synonym yourtable for yourtable;

      Let me know if it doesn't work.

      -Yuri

    Yuri,

    thanks for your reply.

    I don't think it's the problem that's covered in the excerpt from the Oracle doc. The connection can be established for both users with <i>Vendor SQL</i>. For <i>Native SQL</i> it works only with SYSDBA access rights. Moreover, the exception is thrown on the Java statement:

    conn = ((DataSource)ctx.lookup("jdbc/SIS_DS")).getConnection();

    That is, <i>before</i> I use any of my tables.

    That's why I assume WAS tries to access tables outside the applications's schema on opening the connection through the Native SQL layer.

    Regards

    Martin
