    Recently, I did character set alter in my database to AL32UTF32. Now, I cannot run any command on my database. When I am trying to run an alter database command, it shows up ORA 00911: Invalid Character message. When I run startup mount command, it shows a series of inverted 'L'. I am a beginner with oracle. Kindly help me...

    How did you alter the character set in your database? What commands/tools did you use? There is a proper way to change the character set; it appears at first glance that you didn't follow proper procedures. The instructions to do this are here:


    Please report which release of Oracle you're using (and don't say '11g', or '10g' or some such as that helps no one, use the full four to five digit version number) and what steps you performed to change the character set.

    We can't help you until we have this information.
