Re: Oracle JDBC, SQLException, COMMIT is not allowed in a subordinate session

[Anonymous]

I resolved this issue.

If you are using an Oracle XA DataSource, Oracle's JDBC driver
will automatically issue a COMMIT when it sees a "DROP TABLE foobar"
statement.

Oracle's JDBC driver cannot properly execute a
DROP TABLE statement unless you are using a non-XA DataSource.

With the non-XA Oracle JDBC DataSource, I can happily execute
"DROP TABLE foobar"

My configuration:

1) IBM Websphere 5.0.2
2) database: Oracle9i release 2
3) Oracle JDBC DataSource, with XA enabled
4) driver class: oracle.jdbc.xa.client.OracleXADataSource
5) a servlet that uses JTA UserTransaction's

When I execute "DROP TABLE movies", the Oracle JDBC
driver throws a SQLException.

The exception message is

ORA-02089: COMMIT is not allowed in a subordinate session

Oracle's documentation says:

{{

ORA-02089: COMMIT is not allowed in a subordinate session

Cause: COMMIT was issued in a session that is not the two-phase commit
global coordinator.

}}

The strange thing is that I my code does not issue a COMMIT

Also, I disabled autocommit by calling

conn.setAutoCommit(false)

Here is the stack trace:

[7/19/03 12:10:02:936 PDT] 587e316 SystemErr R strMsg =
java.sql.SQLException: ORA-02089: COMMIT is not allowed in a
subordinate session
[...]

The commit is NOT issued by the driver; it is issued by the database. Log
in to sqlplus and prove it to yourself.
eg
update something
drop a table
rollback
and the update will not be rolled back.

Gentlemen,

To add a more general level to this thread: in Oracle *all* ddl statements have
an implied commit associated to them. That is: any creation, removal or change
of a database object forces a commit on the current transaction.

Ruud de Koter.
