To resolve this error, edit the `toolkit.properties` file, specifying valid connection information for the target database in the `TARGET_DB_URL` property.

### Error with time zone region or unsupported character set

*When I try to perform a migration from an Oracle database with Migration Toolkit, I get one or both of the following errors:*

```text
MTK-11009: Error Connecting Database "Oracle"
DB-604: java.sql.SQLException: ORA-00604: error occurred at recursive SQL level 1
ORA-01882: timezone region not found
```

```text
MTK-11009: Error Connecting Database "Oracle"
DB-17056: java.sql.SQLException: Non supported character set (add orai18n.jar in your classpath): ZHS16GBK
```

To resolve this issue you must align the time zone Migration Toolkit is using for the migration with the time zone of the Oracle database. You can do this by specifying the time zone of the Oracle database in the `runMTK.sh` file.

Since MTK is also supported on Windows, we need to provide similar guidelines for runMTK.bat script.


1. Find out which time zone your Oracle database is using.

For example, you can run `SELECT sessiontimezone FROM dual;` to get the time zone value (for example +08:00), or run `SELECT * FROM v$timezone_file;` to understand which time zone file is being used by your Oracle instance.

1. Update the `runMTK.sh` file adding the option `-Duser.timezone=GMT`.

For example, if this was the original line in `runMTK.sh`:

```
runJREApplication $JAVA_HEAP_SIZE -Dprop=$base/etc/toolkit.properties -cp $base/bin/edb-migrationtoolkit.jar:$base/lib/* com.edb.MigrationToolkit "$@"
```

Add the `-Duser.timezone=GMT+08:00` option while ensuring it is placed before the `-Dprop` option.

```
runJREApplication $JAVA_HEAP_SIZE -Duser.timezone=GMT+08:00 -Dprop=$base/etc/toolkit.properties -cp $base/bin/edb-migrationtoolkit.jar:$base/lib/* com.edb.MigrationToolkit "$@"
```

1. Set the classpath environment variable to the JAR internationalization file to ensure Migration Toolkit has access to it:

```
export CLASSPATH=$CLASSPATH:$ORACLE_HOME/jlib/orai18n.jar
```

1. Copy `orai18n.jar` and `ojdbc14.jar` from `/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/jlib/` and `/usr/lib/oracle/xe/app/oracle/product/10.2.0/server/jdbc/lib/` to `/usr/edb/migrationtoolkit/lib` respectively to enable the updated libraries to be recognized by Migration Toolkit.
