The tables in recycle bin can be viewed by 'show recyclebin';

SQL> DROP TABLE RECYCLE;
Table dropped.
SQL> show recyclebin;

Correcting it to have the setting enables would solve the above reported issue.

ORA-01119: error in creating database file

After dropping tablespace with including contents, may end up with "ORA-01119: error in creating database file".

Reasons could be
1. Not deleting the datafile with "INCLUDING CONTENTS AND DATAFILES"
2. Provided directory path does not exist
3. Error accessing the directory (read/write permission or misspelling of directory names)
4. Datafile already existing in the current directory

Here is the case with not deleting datafile with drop tablespace,

SQL> DROP TABLESPACE DATATS INCLUDING CONTENTS;
Tablespace dropped.

SQL> CREATE TABLESPACE DATATS LOGGING DATAFILE '/home/database/DATATS1.dbf' SIZE 1G AUTOEXTEND ON NEXT 50M MAXSIZE UNLIMITED EXTENT MANAGEMENT LOCAL SEGMENT SPACE MANAGEMENT AUTO

Exception in thread "main" java.lang.IllegalStateException

When executing a selenium script written in java to use IE/Chrome driver, an exception would have been thrown to check System.setProperty. The code below seems to be exactly right but 'webdriver' is coded as 'Webdriver' in the first argument, and there stands the exception.

File file = new File("G:\\Data\\git\\Test\\lib\\IEDriverServer.exe");
System.setProperty("Webdriver.ie.driver", file.getAbsolutePath());
WebDriver driver = new InternetExplorerDriver();


Exception in thread "main" java.lang.IllegalStateException: The path to the driver executable must be set by the webdriver.ie.driver system property; for more information, see http://code.google.com/p/selenium/wiki/InternetExplorerDriver.
