11g XE: could not find the given license file

Question

I'm trying to create a simple full-text index like this:

exec ctx_ddl.create_preference('my_own_lexer', 'AUTO_LEXER');

create index myidx ON tbl(name) 
   INDEXTYPE IS ctxsys.context PARAMETERS ('LEXER my_own_lexer')

Got error:

ORA-29855: error occurred in the execution of ODCIINDEXCREATE routine
ORA-20000: Oracle Text error:
DRG-10502: index IDX does not exist
DRG-00100: internal error, arguments : [50611],[drli.c],[2743],[License Error:
could not find the given license file:
/u01/app/oracle/product/11.2.0/xe/ctx/data/inxight/lang/license.dat],[]
ORA-06512: at "CTXSYS.DRUE", line 160
ORA-06512: at "CTXSYS.TEXTINDEXMETHODS", line 366

Using BASIC_LEXER instead of AUTO_LEXER - works without errors

centOS, Oracle Database 11g Express Edition Release 11.2.0.2.0 - 64bit Beta

thanx!

Answer 1

Oracle XE 11gR2 is a beta product. But Express Edition is a restricted product, lacking some of the functionality included in the bigger product. So this may be a bug or a feature by design. The licensing documentation doesn't explicitly mention AUTO_LEXER, which we might expect if Oracle had deliberately excluded it, so "bug" is quite likely.

The best thing to do is raise this question on the OTN forum for the product. Members of the XE team read and respond to user feedback there.
