What causes an OCIW32.dll error?
Submitted by: AdministratorYou may receive the following error message when using your JDBC driver for Oracle: "The ordinal 40 could not be loaded in the dynamic link library OCIW32.dll." This problem is caused by an out-of-date version of OCIW32.DLL in your system directory. Some programs install this file in the system directory in order to run. If you remove this file from the system directory you should no longer receive this error.
What transaction isolation levels does the WebLogic jDriver for Oracle support?
Your servlet application may use Oracle Thin Drivers to access a database that includes BLOB fields. If you install and try to use WebLogic jDriver for Oracle and the same code fails and produces an exception similar to the following:
com.roguewave.jdbtools.v2_0.LoginFailureException:
TRANSACTION_READ_UNCOMMITTED isolation level not allowed
The Stack Trace:
com.roguewave.jdbtools.v2_0.LoginFailureException:
TRANSACTION_READ_UNCOMMITTED isolation level not allowed
at
com.roguewave.jdbtools.v2_0.jdbc.JDBCServer.createConnection
(JDBCServer.java :46)
at com.roguewave.jdbtools.v2_0.ConnectionPool.getConnection_
(ConnectionPool.jav a:412)
at com.roguewave.jdbtools.v2_0.ConnectionPool.getConnection
(ConnectionPool.java :109)
Setting the Isolation_level to 1 in the code that calls the RogueWave JDBCServer class works with the Oracle thin driver but fails with WebLogic jDriver for Oracle.
WebLogic jDriver for Oracle supports the following transaction isolation levels:
SET TRANSACTION ISOLATION LEVEL READ COMMITTED
SET TRANSACTION ISOLATION LEVEL SERIALIZABLE
According to the Oracle documentation, the Oracle DBMS only supports these two isolation levels. Unlike other JDBC drivers, WebLogic's drivers throw an exception if you try to use an isolation level that is unsupported. Some drivers silently ignore attempts to set an unsupported isolation level. WebLogic suggests testing whether the Oracle thin driver is not just ignoring settings for unsupported isolation events.
