I have an issue when trying to change the character set on an Oracle 11.2 database.

Here are the particulars:

  • Oracle 11.2 64 bit, running under Oracle Linux 7
  • This is a new installation (i.e. the only users are those that were created during the Oracle install), using the defaults given during the Oracle installation
  • The current NLS_CHARACTERSET is AL32UTF8, and I need to convert it to either WE8MSWIN1252 or WE8DEC

Most of my experience with Oracle has been with Windows, and I've never had to change the character sets before.

Now I can't just change the character set from AL32UTF8 to WE8DEC or WE8MSWIN1252 because those aren't supersets. So, I ran CSINST.SQL, and ran the CSSCAN command. Most of the scan was successful, but I ended up receiving the following errors:

. processs 1 scanning XDB.PRIN_PT[AAAN9DAACAAAEGoAAA]
ORA-30967: operation directly on the Path Table is disallowed
CSS-00144: failed to scan table XDB.PRIN_PT

Does anyone have any idea what the problem can be and/or how to fix it?

I've done some searching.I did find someone who has mentioned deleting and recreating XML indexes, but I've never done that.

    If this is a new installation, is there a reason that you don't just re-install with the character set that you want? That's generally going to be easier than trying to do a conversion. Functionally, I'm not sure why you'd want to convert away from a Unicode character set but I assume you have your reasons. Commented Oct 25, 2016 at 22:20

This is known issue for Oracle Database version 11.2 or higher where XDB is installed. My Oracle Support says this can be ignored and has been fixed in

Installing and configuring Csscan in 10g and 11g (Database Character Set Scanner) (Doc ID 745809.1)
